    The combination of melphalan, prednisone, and thalidomide (MPT) is considered standard therapy for newly diagnosed patients with multiple myeloma who are ineligible for stem cell transplantation. Long-term treatment with thalidomide is hampered by neurotoxicity. Melphalan, prednisone, and lenalidomide, followed by lenalidomide maintenance therapy, showed promising results without severe neuropathy emerging. We randomly assigned 668 patients between nine 4-week cycles of MPT followed by thalidomide maintenance until disease progression or unacceptable toxicity (MPT-T) and the same MP regimen with thalidomide being replaced by lenalidomide (MPR-R). This multicenter, open-label, randomized phase 3 trial was undertaken by Dutch-Belgium Cooperative Trial Group for Hematology Oncology and the Nordic Myeloma Study Group (the HOVON87/NMSG18 trial). The primary end point was progression-free survival (PFS). A total of 318 patients were randomly assigned to receive MPT-T, and 319 received MPR-R. After a median follow-up of 36 months, PFS with MPT-T was 20 months (95% confidence interval [CI], 18-23 months) vs 23 months (95% CI, 19-27 months) with MPR-R (hazard ratio, 0.87; 95% CI, 0.72-1.04; P = .12). Response rates were similar, with at least a very good partial response of 47% and 45%, respectively. Hematologic toxicity was more pronounced with MPR-R, especially grades 3 and 4 neutropenia: 64% vs 27%. Neuropathy of at least grade 3 was significantly higher in the MPT-T arm: 16% vs 2% in MPR-R, resulting in a significant shorter duration of maintenance therapy (5 vs 17 months in MPR-R), irrespective of age. MPR-R has no advantage over MPT-T concerning efficacy. The toxicity profile differed with clinically significant neuropathy during thalidomide maintenance vs myelosuppression with MPR.

    This multicenter phase II trial evaluated the safety and efficacy of lenalidomide-prednisone (RP) induction, followed by lenalidomide-melphalan-prednisone (MPR) consolidation and RP maintenance in elderly unfit newly diagnosed myeloma patients. Patients received four 28-day RP induction courses (lenalidomide 25 mg/day on days 1-21 and prednisone 50 mg three times/week), followed by six 28-day MPR consolidation cycles (melphalan 2 mg, prednisone 50 mg three times/week and lenalidomide 10-15 mg/day on days 1-21), and maintenance with lenalidomide (10 mg/day on days 1-21 every 28 days) plus prednisone (25 mg three times/week). Forty-six patients were enrolled. Median age was 75 years, 59% of patients had at least one comorbidity and 35% at least two. Partial response rate was 80%, including 29% very good partial response. Median time to progression was 19.6 months, median progression-free survival was 18.4 months and 2-year overall survival was 80%. At the tolerated consolidation dose (melphalan 25 mg/month and lenalidomide 10 mg/day), the most frequent grade 3 adverse events were neutropenia (36.4%), anemia (12.1%), cutaneous reactions (18.2%) and infections (12.1%). Grade 4 neutropenia occurred in 12.1% of patients. In conclusion, RP induction followed by MPR consolidation and RP maintenance showed a manageable safety profile, and reduced the risk of severe hematological toxicity in unfit elderly myeloma patients.

    Full Text Available Plasma cell leukemia (PCL is a rare and aggressive plasma cell disorder, characterized by the presence of a peripheral blood absolute plasma cell count of at least 2×109/l and more than 20% circulating plasma cells. The prognosis of PCL patients remains poor. Even by using autologous or allogenic transplant procedures, median survival does not exceed 3 years (Saccaro et al., 2005. Thalidomide, bortezomib and lenalidomide (Revlimid have emerged as high active agents in the treatment of PCL (Johnston and abdalla, 2002; Musto et al., 2007; Finnegan et al., 2006. In particular, Lenalidomide is a structural analogue of thalidomide with similar but more potent biological activity; it is used as first line therapy in MM (Palumbo et al., 2007; Niesvizky et al., 2007, although information regarding its associated use with dexamethasone use as salvage therapy in PCL derives from anecdotal single case reports (Musto et al., 2008. We would like to describe a case of primary PCL with adverse cytogenetic in which excellent response was achieved with the combination of lenalidomide, melphalan, and prednisone as salvage therapy.

    The MM-015 trial assessed the effect of lenalidomide-based therapy on health-related quality of life. Patients (n=459) with newly diagnosed multiple myeloma aged 65 years or over were randomized 1:1:1 to nine 4-week cycles of lenalidomide, melphalan, and prednisone, followed by lenalidomide maintenance; or lenalidomide, melphalan, and prednisone, or melphalan and prednisone, with no maintenance therapy. Patients completed health-related quality of life questionnaires at baseline, after every third treatment cycle, and at treatment end. Health-related quality of life improved in all treatment groups during induction therapy. Patients receiving lenalidomide maintenance had the most pronounced improvements, Global Health Status/Quality of Life (Plife domains.

    To conduct a cost-effectiveness assessment of lenalidomide plus dexamethasone (Rd) vs bortezomib plus melphalan and prednisone (VMP) as initial treatment for transplant-ineligible patients with newly-diagnosed multiple myeloma (MM), from a U.S. payer perspective. A partitioned survival model was developed to estimate expected life-years (LYs), quality-adjusted LYs (QALYs), direct costs and incremental costs per QALY and LY gained associated with use of Rd vs VMP over a patient's lifetime. Information on the efficacy and safety of Rd and VMP was based on data from multinational phase III clinical trials and a network meta-analysis. Pre-progression direct costs included the costs of Rd and VMP, treatment of adverse events (including prophylaxis) and routine care and monitoring associated with MM. Post-progression direct costs included costs of subsequent treatment(s) and routine care and monitoring for progressive disease, all obtained from published literature and estimated from a U.S. payer perspective. Utilities were obtained from the aforementioned trials. Costs and outcomes were discounted at 3% annually. Relative to VMP, use of Rd was expected to result in an additional 2.22 LYs and 1.47 QALYs (discounted). Patients initiated with Rd were expected to incur an additional $78,977 in mean lifetime direct costs (discounted) vs those initiated with VMP. The incremental costs per QALY and per LY gained with Rd vs VMP were $53,826 and $35,552, respectively. In sensitivity analyses, results were found to be most sensitive to differences in survival associated with Rd vs VMP, the cost of lenalidomide and the discount rate applied to effectiveness outcomes. Rd was expected to result in greater LYs and QALYs compared with VMP, with similar overall costs per LY for each regimen. Results of this analysis indicated that Rd may be a cost-effective alternative to VMP as initial treatment for transplant-ineligible patients with MM, with an incremental cost-effectiveness ratio

    In multiple myeloma (MM), the addition of thalidomide or bortezomib to the standard oral melphalan/prednisone combination significantly increased response rate and event-free survival. In this multicenter phase 1/2 trial, dosing, safety, and efficacy of the 4-drug combination, bortezomib, melphalan, prednisone, and thalidomide (VMPT) was determined. Bortezomib was administered at 3 dose levels (1.0 mg/m2, 1.3 mg/m2, or 1.6 mg/m2) on days 1, 4, 15, and 22; melphalan was given at a dose of 6 mg/m2 on days 1 through 5 and prednisone at 60 mg/m2 on days 1 through 5. Thalidomide was delivered at 50 mg on days 1 through 35. Each course was repeated every 35 days. The maximum tolerated dose of bortezomib was 1.3 mg/m2. Thirty patients with relapsed or refractory MM were enrolled; 20 patients (67%) achieved a partial response (PR) including 13 patients (43%) who achieved at least a very good PR. Among 14 patients who received VMPT as second-line treatment, the PR rate was 79% and the immunofixation-negative complete response rate 36%. The 1-year progression-free survival was 61%, and the 1-year survival from study entry was 84%. Grade 3 nonhematologic adverse events included infections (5 patients), fatigue (1), vasculitis (1), and peripheral neuropathy (2); no grade 4 toxicities were recorded. Initial results showed that VMPT is an effective salvage therapy with a very high proportion of responses. The incidence of neurotoxicities was unexpectedly low.

    The authors report the results of a prospective, multi-centre trial involving 87 patients with previously untreated myeloma who were treated by combination chemotherapy consisting of melphalan, cyclophosphamide, CCNU, prednisone and vincristine. 83.1% of patients had a high tumour mass (stage III on Durie and Salmon's classification). The response to treatment could be evaluated in 76 patients and 70% were found to respond. The median actuarial survival of the whole population is 30 months. The survival is significantly longer (p less than 0.001) in responders (median 40 months) than in non-responders (median: 17 months); the survival is significantly shorter (p less than 0.01) in subjects with renal failure (median: 10 months) than in subjects without renal failure (median: 36 months). This treatment is sufficiently well tolerated to be administered on an outpatient basis. One case of acute monoblastic leukaemia was observed. These results are similar to those reported in the literature.

    The prognosis of multiple myeloma (MM) patients who become refractory to lenalidomide and bortezomib is very poor, indicating the need for new therapeutic strategies for these patients. Next to the development of new drugs, the strategy of combining agents with synergistic activity may also result in clinical benefit for patients with advanced myeloma. We have previously shown in a retrospective analysis that lenalidomide combined with continuous low-dose cyclophosphamide and prednisone (REP) had remarkable activity in heavily pretreated, lenalidomide-refractory MM patients. To evaluate this combination prospectively, we initiated a phase 1/2 study to determine the optimal dose and to assess its efficacy and safety in lenalidomide-refractory MM patients. The maximum tolerated dose (MTD) was defined as 25 mg lenalidomide (days 1-21/28 days), combined with continuous cyclophosphamide (50 mg/day) and prednisone (20 mg/day). At the MTD (n=67 patients), the overall response rate was 67%, and at least minimal response was achieved in 83% of the patients. Median PFS and OS were 12.1 and 29.0 months, respectively. Similar results were achieved in the subset of patients with lenalidomide- and bortezomib-refractory disease as well as in patients with high-risk cytogenetic abnormalities, defined as t(4;14), t(14;16), del(17p), and/or ampl(1q) as assessed by FISH. Neutropenia (22%) and thrombocytopenia (22%) were the most common grade 3-4 hematologic adverse events. Infections (21%) were the most common grade 3-5 non-hematologic adverse events. In conclusion, the addition of continuous low-dose oral cyclophosphamide to lenalidomide and prednisone offers a new therapeutic perspective for multidrug refractory MM patients. This trial was registered at www.clinicaltrials.gov as #NCT01352338.

    We report results of a phase II trial of combination of melphalan, lenalidomide, and dexamethasone for the treatment of immunoglobulin light chain (AL) amyloidosis. The primary objectives were tolerability and hematologic response rate; secondary objectives were organ responses and survival. Treatment protocol consisted of melphalan 5 mg/m(2)/day for four days, lenalidomide 10 mg/day for 21 days and dexamethasone 20-40 mg once a week every 28 days for a total of 12 cycles. Sixteen subjects were enrolled of whom 14 completed at least 3 cycles and were evaluable for response. Grade 3/4 toxicities were experienced by 88% (n=14), the most common being myelosuppression (n=7). Dose reductions occurred in 85% (n=12 of 14) of subjects. Hematologic partial and complete responses were achieved by 43% (n=6 of 14) and 7% (n=1 of 14), respectively. The median overall survival has not been reached and median progression-free survival is 24 months. In conclusion, this combination is associated with significant myelosuppression leading to dose modifications and producing minor hematologic responses in AL amyloidosis. http://clinicaltrials.gov/ct2/show/NCT00679367.

    The initial analysis of the oral combination melphalan, prednisone, and thalidomide (MPT) in newly diagnosed patients with myeloma showed significantly higher response rate and longer progression-free survival (PFS) than did the standard melphalan and prednisone (MP) combination and suggested a survival advantage. In this updated analysis, efficacy and safety end points were updated. Patients were randomly assigned to receive oral MPT or MP alone. Updated analysis was by intention to treat and included PFS, overall survival (OS), and survival after progression. After a median follow-up of 38.1 months, the median PFS was 21.8 months for MPT and 14.5 months for MP (P = .004). The median OS was 45.0 months for MPT and 47.6 months for MP (P = .79). In different patient subgroups, MPT improved PFS irrespective of age, serum concentrations of beta(2)-microglobulin, or high International Staging System. Thalidomide or bortezomib administration as salvage regimens significantly improved survival after progression in the MP group (P = .002) but not in the MPT group (P = .34). These data confirm activity of MPT for PFS but failed to show any survival advantage. New agents in the management of relapsed disease could explain this finding. The study is registered at www.clinicaltrials.gov as #NCT00232934.

    We assessed efficacy, safety, and reversal of renal impairment (RI) in untreated patients with multiple myeloma given bortezomib-melphalan-prednisone-thalidomide followed by bortezomib-thalidomide (VMPT-VT) maintenance or bortezomib-melphalan-prednisone (VMP). Exclusion criteria included serum creatinine ≥ 2.5 mg/dL. In the VMPT-VT/VMP arms, severe RI (estimated glomerular filtration rate [eGFR] ≤ 30 mL/min), moderate RI (eGFR 31-50 mL/min), and normal renal function (eGFR > 50 mL/min), were 6%/7.9%, 24.1%/24.9%, and 69.8%/67.2%, respectively. Statistically significant improvements in overall response rates and progression-free survival were observed in VMPT-VT versus VMP arms across renal cohorts, except in severe RI patients. In the VMPT group, severe RI reduced overall survival (OS). RI was reversed in 16/63 (25.4%) patients receiving VMPT-VT versus 31/77 (40.3%) receiving VMP. Multivariate analysis showed male sex (P = .022) and moderate RI (P = .003) significantly predicted RI recovery. VMP patients achieving renal response showed longer OS. In both arms, greater rates of severe hematologic adverse events were associated with RI (eGFR < 50 mL/min), however, therapy discontinuation rates were unaffected. VMPT-VT was superior to VMP for cases with normal renal function and moderate RI, whereas VMPT-VT failed to outperform VMP in patients with severe RI, although the relatively low number of cases analyzed preclude drawing definitive conclusions. VMPT-VT had no advantage in terms of RI reversal over VMP.

    Lenalidomide, with or without prednisone, is an active therapy for patients with myelofibrosis (MF). We provide an update of a phase II study of lenalidomide plus prednisone in patients with MF, after median follow up of 9 years. Forty patients were enrolled in the study and all patients were evaluable for response. Response to the treatment was reevaluated using IWG response criteria published in 2013: quality of response improved over time and overall response rate was 35%. Response in splenomegaly was seen in 39% of patients and anemia response in 32%. The median time to treatment failure (TTF) in all patients was 8.2 months and the median duration of response was 34.6 months. Response was highly durable in some patients: six patients (15%) had TTF for more than 60 months (5 years) and three patients are still on the treatment beyond 109 months (9 years). Complete and partial responses were seen in one and five patients, respectively, but achieving deeper response was not necessary for the response to be durable. New clinical studies are needed to explore safe and well tolerated lenalidomide-based combination strategies for patients with MF.

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone-treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment.

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone–treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment. PMID:26659916

    Lenalidomide (Revlimid(®)) is a second-generation immunomodulatory drug structurally related to thalidomide, with improved efficacy and tolerability, for which the label in the EU was recently expanded to include continuous therapy in patients with previously untreated multiple myeloma not eligible for stem-cell transplantation. In randomized, controlled clinical trials, continuous lenalidomide therapy, either in combination with dexamethasone (FIRST trial) or as maintenance monotherapy following induction with melphalan/prednisone/lenalidomide (MM-015 trial), significantly improved progression-free survival (PFS) compared with induction therapy alone (with non-lenalidomide- or lenalidomide-containing regimens) in patients with newly diagnosed multiple myeloma not eligible for stem-cell transplantation. The improvements in PFS with continuous lenalidomide were reflected in improved health-related quality-of-life measures. An overall survival benefit was observed in the FIRST trial, but not in the MM-015 trial. Continuous lenalidomide and continuous thalidomide regimens displayed similar efficacy, but lenalidomide was associated with significantly less toxicity than thalidomide. Continuous use of lenalidomide did not appear to negatively impact on the drug's tolerability and did not increase the incidence of neutropenia or second primary malignancy compared with shorter-term use. The incidence of most adverse events began to reduce after about 18 months of therapy. In conclusion, continuous lenalidomide regimens provide an effective longer-term treatment option in patients with newly diagnosed multiple myeloma ineligible for stem-cell transplantation.

    This single institution, open label Phase I-II dose escalation trial evaluated the safety and efficacy of the combination of lenalidomide (Revlimid®), cyclophosphamide and prednisone (CPR) in patients with relapsed/refractory multiple myeloma. The maximal administered dose of CPR consisted of cyclophosphamide 300 mg/m(2) on day 1, 8, and 15, lenalidomide 25 mg on d 1-21 and prednisone 100 mg every other day in a 28-d cycle. Between November 2007 and June 2009, 32 patients were entered in cohorts of three at three dose levels. The median age was 64 years, 59% were male, with a median two prior regimens. Responding patients could stay on treatment until progression. The full-dose CPR regimen produced no dose-limiting toxicity and was delivered for a median of 16 months (3·5-65 months) with acceptable safety and tolerance. The overall response rate (≥ partial response) was 94% at a median follow up of 28 months. The median progression-free survival was 16·1 months [95% confidence interval (CI); 10·9-22·5 months], while the median overall survival was 27·6 months (95% CI; 16·8-36·6 months). Only the beta-2 microglobulin level at protocol entry correlated with a better survival (P = 0·047). These observations compare favourably with other 2- and 3- drug combinations for relapsed/refractory myeloma, and suggest that CPR should be evaluated further in the setting of relapsed/refractory disease, or in newly diagnosed patients.

    Lenalidomide (Revlimid®) combined with intermittent dexamethasone (the RD regimen) is one of the current standards for treatment of patients with relapsed/refractory multiple myeloma (MM). However, since the disease in the majority of patients will become resistant to RD, or treatment with RD needs to be discontinued due to side effects, we evaluated the combination lenalidomide, low-dose oral cyclophosphamide, with prednisone (REP) in patients with relapsed/refractory MM previously exposed to RD. For this purpose, we performed a single centre retrospective study of the efficacy of REP in 19 patients with relapsed/refractory MM. Overall response rate (partial response or better) with REP was 68% compared with 83% with RD, but with a shorter time to response with the triplet REP. Time to progression after REP was 6 months. Overall the REP regimen was better tolerated compared to RD. We conclude that the REP regimen is an effective treatment regimen for patients with relapsed/refractory MM with good tolerance, warranting further exploration in prospective randomized trials.

    Lenalidomide-dexamethasone improved outcome in newly diagnosed elderly multiple myeloma patients. We randomly assigned 662 patients who were age ≥65 years or transplantation-ineligible to receive induction with melphalan-prednisone-lenalidomide (MPR) or cyclophosphamide-prednisone-lenalidomide (CPR) or lenalidomide plus low-dose dexamethasone (Rd). The primary end point was progression-free survival (PFS) in triplet (MPR and CPR) vs doublet (Rd) lenalidomide-containing regimens. After a median follow-up of 39 months, the median PFS was 22 months for the triplet combinations and 21 months for the doublet (P = .284). The median overall survival (OS) was not reached in either arms, and the 4-year OS was 67% for the triplet and 58% for the doublet arms (P = .709). By considering the 3 treatment arms separately, no difference in outcome was detected among MPR, CPR, and Rd. The most common grade ≥3 toxicity was neutropenia: 64% in MPR, 29% in CPR, and 25% in Rd patients (P < .0001). Grade ≥3 nonhematologic toxicities were similar among arms and were mainly infections (6.5% to 11%), constitutional (3.5% to 9.5%), and cardiac (4.5% to 6%), with no difference among the arms. In conclusion, in the overall population, the alkylator-containing triplets MPR and CPR were not superior to the alkylator-free doublet Rd, which was associated with lower toxicity. This study was registered at www.clinicaltrials.gov as #NCT01093196.

    In this project, we produced drug-specific recommendations targeting the use of new agents for multiple myeloma (MM). We used the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) system which separates the judgments on quality of evidence from the judgment about strength of recommendations. We recommended thalidomide and bortezomib in MM patients candidates to autologous stem cell transplantation (ASCT) (weak positive). We did not recommend novel agents as maintenance therapy after ASCT (weak negative). In patients not candidate to ASCT, thalidomide or bortezomib (strong positive) associated with melphalan and prednisone were recommended. In these patients, no specific course of action could be recommended as for maintenance therapy. In patients who are refractory or relapsing after first-line therapy, we recommended bortezomib and pegylated liposomal doxorubicin, or lenalidomide and dexamethasone combinations (weak positive).

    Full Text Available Novel agents such as lenalidomide have demonstrated responses similar to high-dose melphalan and autologous stem cell transplant in multiple myeloma. For patients who are started on lenalidomide, it is advisable to collect stem cells early if future transplant is contemplated. We are reporting a patient who underwent successful stem cell mobilization after 68 cycles of lenalidomide. A 60-year old male presented with back pain. He was diagnosed with stage IIA, IgA multiple myeloma. He was enrolled in a clinical trial and was randomized to receive lenalidomide plus dexamethasone. He received a total of 68 cycles of lenalidomide before progressing. He underwent mobilization of stem cells using filgrastim and plerixafor. He underwent successful stem cell transplant. Longer duration of lenalidomide adversely effects stem cell mobilization. To the best of our knowledge, there has been no other case reported in which stem cell mobilization was feasible after such a long (68 months duration of uninterrupted lenalidomide therapy.

    Full Text Available Lenalidomide is a potent immunomodulatory agent being used increasingly for treatment of hematologic malignancies including multiple myeloma and myelodysplasia. The common toxicities of lenalidomide, including dose-limiting myelosuppression, are well described. However, the immunomodulatory properties of lenalidomide may give rise to unexpected autoimmune complications. Herein, we describe a case of immune thrombocytopenic purpura (ITP associated with use of lenalidomide.

    PURPOSE To evaluate the effect of bortezomib as induction therapy before autologous transplantation, followed by lenalidomide as consolidation-maintenance in myeloma patients. PATIENTS AND METHODS Newly diagnosed patients age 65 to 75 years were eligible. Induction (bortezomib, doxorubicin, and dexamethasone [PAD]) included four 21-day cycles of bortezomib (1.3 mg/m(2) on days 1, 4, 8, and 11), pegylated liposomal doxorubicin (30 mg/m(2) on day 4), and dexamethasone (40 mg/d; cycle 1: days 1 to 4, 8 to 11, and 15 to 18; cycles 2 to 4: days 1 to 4). Autologous transplantation was tandem melphalan 100 mg/m(2) (MEL100) and stem-cell support. Consolidation included four 28-day cycles of lenalidomide (25 mg/d on days 1 to 21 every 28 days) plus prednisone (50 mg every other day), followed by maintenance with lenalidomide (LP-L; 10 mg/d on days 1 to 21) until relapse. Primary end points were safety (incidence of grade 3 to 4 adverse events [AEs]) and efficacy (response rate). Results A total of 102 patients were enrolled. In a per-protocol analysis, after PAD, 58% of patients had very good partial response (VGPR) or better, including 13% with complete response (CR); after MEL100, 82% of patients had at least VGPR and 38% had CR; and after LP-L, 86% of patients had at least VGPR and 66% had CR. After median follow-up time of 21 months, the 2-year progression-free survival rate was 69%, and the 2-year overall survival rate was 86%. During induction, treatment-related mortality was 3%; grade 3 to 4 AEs included thrombocytopenia (17%), neutropenia (10%), peripheral neuropathy (16%), and pneumonia (10%). During consolidation-maintenance, grade 3 to 4 AEs were neutropenia (16%), thrombocytopenia (6%), pneumonia (5%), and cutaneous rash (4%). CONCLUSION Bortezomib as induction before autologous transplantation, followed by lenalidomide as consolidation-maintenance, is an effective regimen.

    Objective Cutaneous manifestations of pediatric systemic lupus erythematosus cause significant morbidity. Lenalidomide, a thalidomide analogue, has shown promise treating cutaneous lupus erythematosus in adults. Our objective was to evaluate lenalidomide's efficacy and safety in treating refractory cutaneous manifestations of pediatric systemic lupus erythematosus. Methods We performed a retrospective chart review of 10 adolescents who received lenalidomide for recalcitrant cutaneous lupus erythematosus. Information was gathered at drug initiation and 6-month follow-up. The Wilcoxon matched-pairs signed-rank test was used to assess change in quantitative parameters of disease activity. Results Nine subjects were girls and six were African-American. Indications for lenalidomide treatment included alopecia, nasal and oral ulcers, extensive malar rash, discoid lesions, bullous lesions, panniculitis, cutaneous vasculitis, and Raynaud's phenomenon with digital ulcerations. Within 6 months, all patients demonstrated complete or near resolution based on physician report. Prednisone dose decreased from a mean 23.5 mg (SD± 13.3) to 12.25 mg (SD± 9.2) ( P= 0.008). Sedimentation rate decreased from a mean 29 mm/hour (SD± 31.5) to 17 mm/hour (SD± 18.1) ( P= 0.004). Lenalidomide was well tolerated. Conclusion Lenalidomide is an effective and safe treatment for a spectrum of dermatological conditions in pediatric systemic lupus erythematosus. Its use may allow a reduction in prednisone dose and decreased disfigurement. Prospective study is needed to clarify lenalidomide's role in treating cutaneous manifestations of systemic lupus erythematosus.

    To identify molecular targets that modify sensitivity to lenalidomide, we measured proliferation in multiple myeloma (MM) cells transfected with 27 968 small interfering RNAs in the presence of increasing concentrations of drug and identified 63 genes that enhance activity of lenalidomide upon silencing. Ribosomal protein S6 kinase (RPS6KA3 or RSK2) was the most potent sensitizer. Other notable gene targets included 5 RAB family members, 3 potassium channel proteins, and 2 peroxisome family members. Single genes of interest included I-κ-B kinase-α (CHUK), and a phosphorylation dependent transcription factor (CREB1), which associate with RSK2 to regulate several signaling pathways. RSK2 knockdown induced cytotoxicity across a panel of MM cell lines and consistently increased sensitivity to lenalidomide. Accordingly, 3 small molecular inhibitors of RSK2 demonstrated synergy with lenalidomide cytotoxicity in MM cells even in the presence of stromal contact. Both RSK2 knockdown and small molecule inhibition downregulate interferon regulatory factor 4 and MYC, and provides an explanation for the synergy between lenalidomide and RSK2 inhibition. Interestingly, RSK2 inhibition also sensitized MM cells to bortezomib, melphalan, and dexamethasone, but did not downregulate Ikaros or influence lenalidomide-mediated downregulation of tumor necrosis factor-α or increase lenalidomide-induced IL-2 upregulation. In summary, inhibition of RSK2 may prove a broadly useful adjunct to MM therapy.

    The phase 3 FIRST (Frontline Investigation of REVLIMID + Dexamethasone Versus Standard Thalidomide) trial demonstrated that lenalidomide plus low-dose dexamethasone (Rd) until disease progression (Rd continuous) is an effective treatment option for transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). Given genetic differences between Asian and Western populations, this subanalysis of the FIRST trial examined the safety and efficacy of Rd (given continuously or for 18 cycles [Rd18]) and MPT (melphalan, prednisone, thalidomide) in 114 Asian patients from Mainland China, South Korea and Taiwan. Efficacy and safety with Rd continuous in Asian patients were consistent with those in the overall study population. The overall response rates were 77·8% for Rd continuous, 57·5% for MPT and 65·8% for Rd18. The risk of progression or death was reduced by 39% with Rd continuous versus MPT and by 35% with Rd continuous versus Rd18. Rd continuous improved the 3-year survival rate compared with MPT (70·2% vs. 56·4%) and Rd18 (58·1%). Common grade 3/4 adverse events in the Rd continuous and MPT arms were neutropenia (25·0% vs. 43·6%), infection (19·4% vs. 28·2%) and anaemia (19·4% vs. 15·4%), respectively. Thromboembolic event rates were low, and no second primary malignancies were observed. Rd continuous is safe and effective in transplant-ineligible Asian patients with NDMM.

    2011-11-03

    The precise molecular mechanism of action and targets through which thalidomide and related immunomodulatory drugs (IMiDs) exert their antitumor effects remains unclear. We investigated the role of cereblon (CRBN), a primary teratogenic target of thalidomide, in the antimyeloma activity of IMiDs. CRBN depletion is initially cytotoxic to human myeloma cells, but surviving cells with stable CRBN depletion become highly resistant to both lenalidomide and pomalidomide, but not to the unrelated drugs bortezomib, dexamethasone, and melphalan. Acquired deletion of CRBN was found to be the primary genetic event differentiating isogenic MM1.S cell lines cultured to be sensitive or resistant to lenalidomide and pomalidomide. Gene expression changes induced by lenalidomide were dramatically suppressed in the presence of CRBN depletion, further demonstrating that CRBN is required for lenalidomide activity. Downstream targets of CRBN include interferon regulatory factor 4 (IRF4) previously reported to also be a target of lenalidomide. Patients exposed to, and putatively resistant to, lenalidomide had lower CRBN levels in paired samples before and after therapy. In summary, CRBN is an essential requirement for IMiD activity and a possible biomarker for the clinical assessment of antimyeloma efficacy.

    New drugs for the treatment of multiple myeloma (MM) comprise immunomodulatory substances such as lenalidomide and related compounds. While lenalidomide has found its way into first-line treatment as well as into relapse therapy, little is known about lenalidomide effects on normal hematopoietic stem and progenitor cells (HSPCs). In this study, we investigated whether HSPCs are influenced by lenalidomide on a phenotypic, functional and gene expression level. For that purpose, samples from patients with MM were obtained who underwent equivalent first-line treatment including induction therapy, cytotoxic stem cell mobilization and high-dose melphalan therapy followed by autologous blood stem cell transplantation and a subsequent uniform lenalidomide consolidation treatment within a prospective clinical trial. We found that after six months of lenalidomide therapy, the number of CD34(+) HSPCs decreased. Additionally, lenalidomide affects the numerical composition of hematopoietic cells in the bone marrow while it does not affect long-term HSPC proliferation in vitro. We found a significant amplification of fetal hemoglobin (HbF) expression on a transcriptional level and can confirm a stimulated erythropoiesis on a phenotypic level. These effects were accompanied by silencing of the TGF-β signaling pathway on the gene expression and protein level that is known to be amplified in active MM. However, these pleiotropic effects gave no evidence for mutagenic potential. In conclusion, lenalidomide does not exert long-term effects on proliferation of HSPCs but instead promotes erythropoiesis by shifting hemoglobin expression toward HbF and by silencing the TGF-β signaling pathway.

    Relapsed/refractory diffuse large B-cell lymphoma (DLBCL) is associated with a poor prognosis. Outcomes are particularly poor following immunochemotherapy failure or relapse within 12 months of induction. We conducted a Phase I/II trial of lenalidomide plus RICE (rituximab, ifosfamide, carboplatin, and etoposide) (RICER) as a salvage regimen for first-relapse or primary refractory DLBCL. Dose-escalated lenalidomide was combined with RICE every 14 d. After three cycles of RICER, patients with chemosensitive disease underwent stem cell collection and consolidation with BEAM [BCNU (carmustine), etoposide, cytarabine, melphalan] followed by autologous stem cell transplantation (autoSCT). Patients who recovered from autoSCT toxicities within 90 d initiated maintenance treatment with lenalidomide 25 mg daily for 21 d every 28 d for 12 months. No dose-limiting or unexpected toxicities occurred with lenalidomide 25 mg plus RICE. Grade 3/4 haematological toxicities resolved appropriately, and planned dose density and dose intensity of RICER were preserved. No lenalidomide or RICE dose reductions were required in any of the three cycles. After two cycles of RICER, nine of 15 patients (60%) achieved a complete response, and two achieved a partial response (13%). Combining lenalidomide with RICE is feasible, and results in promising response rates (particularly complete response rates) in high-risk DLBCL patients.

    Full Text Available We report the activity of lenalidomide (revlimide – R, lenalidomide plus dexamethasone (Rd, lenalidomide plus bortezomib plus dexamethasone (RVd in 34 patients with relapsed and refractory myeloma. For patients who received lenalidomide the overall response rate was 70.5 %. 38 % patients achieved very good partial response (VGPR + complete response (CR. Median overall survival (OS was 48 months. Lenalidomide may overcome the poor prognostic impact of various factors, particularly elevated beta (2-microglobulin. Lenalidomide is highly active in elderly patients (> 65 years. Significantly increased OS with a lenalidomide-based induction and lenalidomide maintenance therapy was revealed. The median duration of the overall response without lenalidomide maintenance therapy was 10 months. The median duration of the overall response with lenalidomide maintenance therapy was 20 months (р < 0,05. Median OS with lenalidomide maintenance therapy was not reached. Median OS without lenalidomide maintenance therapy was 36 months (р < 0.05. Side effects were predictable and manageable. The most common adverse events reported were neutropenia (38.3 % and thrombocytopenia (23.7 %. Serious adverse events were rare.

    Lenalidomide is an immunomodulatory agent (IMiD) that has activity in hematologic cancer (e.g., multiple myeloma). The immunomodulatory and apoptotic properties are readily apparent in therapy. However, the exact mechanism of action has been difficult to quantify until recently when it was shown that another IMiD, thalidomide, binds to an E3 ubiquitin ligase complex constituent, CRBN. The article by Kronke et al. demonstrates that, by binding to CRBN and altering its selectivity, lenalidomide potentiates the ubiquitination and proteolysis of 2 specific proteins, IKZF1 and IKZF3. An article in the same issue, by Lu et al., supports these observations. IKZF1 and IKZF3 are transcription factors that are necessary for multiple myeloma, and repression of these transcription factors is a likely mechanism for lenalidomide activity in this disease.

  19. Lenalidomide and Chronic Lymphocytic Leukemia

    Full Text Available Lenalidomide is an oral immunomodulatory drug used in multiple myeloma and myelodysplastic syndrome and most recently it has shown to be effective in the treatment of various lymphoproliferative disorders such as chronic lymphocytic leukemia (CLL and non-Hodgkin lymphoma. The mechanism of action of lenalidomide varies depending on the pathology, and in the case of CLL, it appears to primarily act by restoring the damaged mechanisms of tumour immunosurveillance. This review discusses the potential mechanism of action and efficacy of lenalidomide, alone or in combination, in treatment of CLL and its toxic effects such as tumor lysis syndrome (TLS and tumor flare reaction (TFR, that make its management different from other hematologic malignancies.

    Whether the efficacy of lenalidomide in the treatment of multiple myeloma (MM) is due to direct tumor toxicity only or to additional immunomodulatory effects is unclear. We studied the effect of lenalidomide treatment on T-cell immune reconstitution in patients with MM who had undergone autologous peripheral blood stem cell transplant (ASCT). Twenty-nine newly diagnosed patients with MM received induction therapy followed by high-dose melphalan and ASCT. After ASCT, 11 patients received lenalidomide consolidation therapy for 2 months followed by maintenance therapy until disease progression. The remaining 18 patients received no treatment. Serial analysis of thymic output, as given by numbers of T-cell receptor excision circles (sjTRECs), and T-cell phenotyping was performed until 18 months post-ASCT. Lenalidomide impaired long-term thymic T-cell reconstitution, decreased CD4 + and CD8 + CD45RA + CCR7 - effector-terminal T-cell absolute counts and increased CD4 + CD25 + CD127 - /low regulatory T-cells. Lenalidomide consolidation and long-term maintenance therapy, administered post-ASCT, may have a potentially negative impact on immune surveillance.

  2. Clinical Pharmacokinetics and Pharmacodynamics of Lenalidomide.

    Lenalidomide is a lead therapeutic in multiple myeloma and deletion 5q myelodysplastic syndromes and shows promising activities in other hematologic malignancies. This article presents a comprehensive review of the clinical pharmacokinetics and pharmacodynamics of lenalidomide. Oral lenalidomide is rapidly and highly absorbed (>90 % of dose) under fasting conditions. Food affects oral absorption, reducing area under the concentration-time curve (AUC) by 20 % and maximum concentration (C max) by 50 %. The increase in AUC and C max is dose proportional, and interindividual variability in plasma exposure is low to moderate. Lenalidomide distributes into semen but is undetectable 3 days after stopping treatment. Biotransformation of lenalidomide in humans includes chiral inversion, trivial hydroxylation, and slow non-enzymatic hydrolysis. Approximately 82 % of an oral dose is excreted as lenalidomide in urine within 24 h. Lenalidomide has a short half-life (3-4 h) and does not accumulate in plasma upon repeated dosing. Its pharmacokinetics are consistent across patient populations, regardless of the type of hematologic malignancy. Renal function is the only important factor affecting lenalidomide plasma exposure. Lenalidomide has no QT prolongation risk at approved doses, and higher plasma exposure to lenalidomide is associated with increased risk of neutropenia and thrombocytopenia. Despite being a weak substrate of P-glycoprotein (P-gp) in vitro, lenalidomide does not have clinically significant pharmacokinetic interactions with P-gp substrates/inhibitors in controlled studies. The AUC-matched dose adjustment is recommended for patients with renal impairment at the start of therapy. No dose adjustment for lenalidomide is needed on the basis of age, ethnicity, mild hepatic impairment, or drug-drug interactions.

    Although autologous stem cell transplantation or melphalan-based chemotherapy has significantly improved the prognosis of POEMS syndrome, a few patients will relapse or be refractory to primary therapy, and there is a lack of studies regarding these patients. In this study, we used low-dose lenalidomide (10 mg daily) and dexamethasone (40 mg, once weekly) to treat twelve patients with relapsed (n = 8) or refractory (n = 4) POEMS syndrome. After a median follow-up time of 20 months, the overall hematologic response rate was 77% with 44% having a complete response. Eight (67%) patients had neurological response, and the median overall neuropathy limitation scale score was reduced from 3 (range, 1-9) to 2 (range, 0-6). Serum vascular endothelial growth factor response rate was 91% and 46% of patients had normal serum VEGF levels. One patient had progression of the disease 3 months after the end of treatment and subsequently died from the disease. Therefore, the estimated 2 year overall survival and progression-free survival were 92%. The low-dose lenalidomide and dexamethasone regimen was well tolerated, with no treatment-related death or any grade 3 or 4 toxicity. In conclusion, low-dose lenalidomide plus dexamethasone therapy is an effective and safe regimen for patients with relapsed or refractory POEMS syndrome.

    Nineteen patients obstinate with cluster headaches whose pain was not mitigated by standard treatment (Methysergide, caffeine, ergotamine preparation, phenobarbital and analgesics) underwent a double blind control study with single crossover for the evaluation of prednisone therapy. Compared to placebo, a single oral dose of prednisone in 17 cases produced sustained improvement. Maintenance administration of prednisone was also effective in decreasing the frequency of attacks; however a single dose of the steroid when headaches began was effective.

    Fink, Emma C; Ebert, Benjamin L

    2015-11-19

    Lenalidomide acts by a novel drug mechanism-modulation of the substrate specificity of the CRL4(CRBN) E3 ubiquitin ligase. In multiple myeloma, lenalidomide induces the ubiquitination of IKZF1 and IKZF3 by CRL4(CRBN). Subsequent proteasomal degradation of these transcription factors kills multiple myeloma cells. In del(5q) myelodysplastic syndrome, lenalidomide induces the degradation of CK1α, which preferentially affects del(5q) cells because they express this gene at haploinsufficient levels. In the future, modulation of ubiquitin ligase function may enable us to target previously "undruggable" proteins.

    We conducted a randomized, controlled trial comparing thalidomide-prednisone as maintenance therapy with observation in 332 patients who had undergone autologous stem cell transplantation with melphalan 200 mg/m2. The primary end point was overall survival (OS); secondary end points were myeloma-specific progression-free survival,progression-free survival, incidence of venous thromboembolism, and health-related quality of life (HRQoL). With a median follow-up of 4.1 years, no differences in OS between thalidomide-prednisone and observation were detected (respective 4-year estimates of 68% vs 60%, respectively; hazard ratio = 0.77; P = .18); thalidomide-prednisone was associated with superior myeloma-specific progression-free survival and progression-free survival (for both outcomes, the 4-year estimates were 32% vs 14%; hazard ratio = 0.56; P prednisone and 34.1 months in the observation group. Nine second malignancies were observed with thalidomide-prednisone versus 6 in the observation group. Those allocated to thalidomide-prednisone reported worse HRQoL with respect to cognitive function, dyspnea, constipation, thirst, leg swelling, numbness, dry mouth, and balance problems. We conclude that maintenance therapy with thalidomide-prednisone after autologous stem cell transplantation improves the duration of disease control, but is associated with worsening of patient-reported HRQoL and no detectable OS benefit.

    Diffuse large B-cell lymphoma (DLBCL) patients failing rituximab-containing therapy have a poor outcome with the current salvage regimens. We conducted a phase 1b trial to determine the maximum tolerated dose (MTD) of lenalidomide in combination with R-ESHAP (rituximab, etoposide, cisplatin, cytarabine, methylprednisolone) (LR-ESHAP) in patients with relapsed or refractory DLBCL. Efficacy data were collected as a secondary objective. Subjects received 3 cycles of lenalidomide at escalating doses (5, 10 or 15 mg) given on days 1-14 of every 21-day cycle, in combination with R-ESHAP. Responding patients received BEAM (carmustine, etoposide, cytarabine, melphalan) followed by autologous stem-cell transplantation. Lenalidomide 10 mg/d was identified as the MTD because, in the 15 mg cohort, one patient experienced dose-limiting toxicity (grade 3 angioedema) and two patients had mobilization failure. A total of 19 patients (3, 12 and 4 in the 5, 10 and 15 mg cohorts, respectively) were evaluable. All toxicities occurring during LR-ESHAP cycles resolved appropriately and no grade 4-5 non-haematological toxicities were observed. The complete remission and overall response rates were 47·4% and 78·9%, respectively. With a median follow-up of 24·6 (17·4-38·2) months, the 2-year progression-free survival and overall survival were 44% and 63%, respectively. In conclusion, the LR-ESHAP regimen is feasible and yields encouraging outcomes.

    Melphalan represents the reference drug for locoregional chemotherapy of melanoma; nevertheless, treatment failure may occur because of resistance to chemotherapy. Refractory melanoma cells show either an increased capability of drug inactivation, which is known to be associated with elevated intracellular levels of glutathione (GSH), or a decreased melphalan uptake. The aim of this study was to explore a biochemical and a biophysical strategy, and their combination, to overcome melphalan resistance in melanoma cells. The biochemical strategy was based on the treatment of melanoma cells with DL-buthionine (S,R)-sulfoximine (BSO) to deplete the GSH levels, thus reducing melphalan inactivation. In the biophysical strategy, cell membrane electroporation was used to increase melphalan uptake. The SK-MEL 28-resistant human melanoma cell line was pretreated with 50 μmol/l BSO for 24 h and then treated with increasing melphalan doses, with or without electroporation. Spectrophotometric quantification of cell viability was used to determine melphalan cytotoxicity. Intracellular total GSH was measured using a kinetic enzymatic assay. BSO induced 3.50-fold GSH depletion in untreated cells and a similar reduction was also maintained in melphalan-treated cells. BSO pretreatment produced a 2.46-fold increase in melphalan cytotoxicity. Electroporation increased melphalan cytotoxicity 1.42-fold. The combination of both BSO pretreatment with melphalan plus electroporation led to a 4.40-fold increase in melphalan cytotoxicity compared with melphalan alone. Pretreatment with BSO and cell membrane permeabilization by electroporation enhanced the cytotoxic activity of melphalan in melanoma cells. Their rational combination deserves further investigation and may improve the efficacy of locoregional chemotherapy of melanoma.

    Thalidomide, lenalidomide and pomalidomide have greatly improved the outcome of patients with multiple myeloma. However, their effects on plasma cells, the healthy counterpart of myeloma cells, are unknown. Here, we investigated lenalidomide effects on normal human plasma cell generation using an in vitro model. Lenalidomide inhibited the generation of pre-plasmablasts and early plasma cells, while it moderately affected plasmablast production. It also reduced the expression level of Ikaros, Aiolos, and IRF4 transcription factors, in plasmablasts and early plasma cells. This suggests that their differential sensitivity to lenalidomide is not due to a difference in Ikaros or Aiolos degradation. Lenalidomide also inhibited long-lived plasma cell generation, but did not impair their long-term survival once generated. This last observation is in agreement with the finding that lenalidomide treatment for 3-18 months did not affect the bone marrow healthy plasma cell count in allografted patients with multiple myeloma. Our findings should prompt to investigate whether lenalidomide resistance in patients with multiple myeloma could be associated with the emergence of malignant plasmablasts or long-lived plasma cells that are less sensitive to lenalidomide.

    Melphalan is an important cytotoxic drug. The empirical practice of body surface area-based (BSA) dosing (mg/m2) of melphalan has been critically analyzed in several observations. BSA-based dosing leads to significant variability in doses administered per kilogram of body weight (mg/kg), contributes to increased oral toxicity and probably does not have any significant effect on treatment results within equally BSA (mg/m2) dosed melphalan regimens.

    Lenalidomide treatment in combination with dexamethasone and/or chemotherapy is associated with a significant risk of venous thromboembolism (VTE) in patients with multiple myeloma (MM). However, the incidence of asymptomatic VTE in lenalidomide-treated MM patients remains unclear. A total of 80 relapsed and refractory MM patients treated with lenalidomide-containing regimens in a single institution between July 2010 and July 2014 were retrospectively analyzed. Of these, eight patients had asymptomatic VTE before starting lenalidomide. The remaining 72 patients received thromboprophylaxis with low-dose aspirin (100 mg daily) and monitoring of plasma D-dimer levels on each visit. During the median follow-up time of 7.3 months (range 1.0-43.5 months), 29 patients (40.3 %) showed an elevation of D-dimer (≥2.5 μg/mL), and 13 (18.1 %) showed asymptomatic VTE in a lower extremity. Median time to asymptomatic VTE events from initiation of lenalidomide treatment was 3.0 months (range 1.0-13.1 months). All patients having an asymptomatic VTE continued lenalidomide treatment on warfarinization (target international normalized ratio 1.5-2.5), and none of them developed symptomatic VTE. In conclusion, an asymptomatic VTE event occurred in 18 % of Japanese MM patients receiving lenalidomide-containing therapy despite aspirin prophylaxis. Serial monitoring of plasma D-dimer levels and early intervention may help to prevent symptomatic or lethal VTE events.

    Immunomodulation is an important part of lenalidomide's mode of action. We analyzed the impact of lenalidomide on T cells from patients with multiple myeloma during lenalidomide therapy in vivo and in patients with lenalidomide-refractory disease in vitro Patients enrolled in the German Speaking Myeloma Multicenter Group (GMMG) MM5 trial received a consolidation therapy with two cycles of lenalidomide after autologous stem cell transplantation (ASCT). Half of the study population continued treatment with lenalidomide maintenance therapy for 2 y, while the other patients received lenalidomide maintenance therapy until complete remission. We analyzed 58 patients with (n = 30) or without (n = 28) lenalidomide therapy and 12 patients refractory to lenalidomide with regards to their anti-myeloma-specific T-cell responses displayed by IFNγ, Granzyme B, and Perforin secretion. The immunophenotype of T-cells was investigated by flow cytometry. Significantly, more myeloma-specific T-cell responses were observed in patients during lenalidomide therapy, compared to patients without treatment. Furthermore, we found on T-cells from patients treated with lenalidomide a decreased CD45RA expression, indicating a maturated immunophenotype and a decreased expression of CD57, indicating functional T cells. An improved myeloma-specific T-cell response was observed in 6 out of 12 heavily pretreated patients (refractory to lenalidomide) after in vitro incubation with lenalidomide. Complementary to the results in vivo, lenalidomide decreased CD45RA expression on T cells in vitro.

    Prurigo nodularis is a chronic, relapsing neurodermatitis that is often resistant to standard therapies with topical corticosteroids and oral antihistamines. Thalidomide, while efficacious in treating recalcitrant cases of prurigo nodularis, causes significant toxicity. Thalidomide-induced peripheral neuropathy frequently results in drug discontinuation. Lenalidomide (Revlimid; Celgene Corporation, Summit, NJ) is a derivative of thalidomide with less neurotoxicity approved for the treatment of multiple myeloma and myelodysplastic syndromes that has not been widely studied in dermatologic disorders. Here, we report a case of refractory prurigo nodularis effectively treated with lenalidomide. Given its favorable side-effect profile, lenalidomide may offer a superior alternative to thalidomide in the treatment of this condition.

    Full Text Available Acute panmyelosis with myelofibrosis (APMF is a rare, fatal hematological neoplasm that is characterized by the acute onset of cytopenias and fibrosis in the bone marrow in the absence of splenomegaly or fibrosis-related morphological changes in the RBCs. We present the case of a 59-year-old female who presented with a two-month history of anemia, leucopenia and a normal platelet count. The marrow was heavily fibrotic, and no aspirate material could be obtained; the biopsy showed extensive infiltration with small to medium size megakaryocytes, dysplastic changes in the erythroid compartment, and left shift in the myeloid cells. The patient was treated for four months with anabolic steroids (Danazol, growth factors and received regular blood transfusions. At 4 months after diagnosis, the patient was started on Lenalidomide, 10 mg/day for a 21-d-course along with growth factor support. At 6 months after treatment, the patient was transfusion-independent, had normalized blood counts, and, at 32 months on continuous lenalidomide treatment, her needs for growth factor support have been minimized. Repeat bone marrow biopsies showed a patchy distribution of fibrosis with areas of normal cellularity and morphology. To our knowledge, this is the first case for a medication that could reverse the fatal outcome of APMF.

    Lenalidomide is an immunomodulatory agent that was approved for the treatment of a monoclonal bone marrow disorders, myelodysplastic syndrome del(5q)(MDS del(5q)), in 2005; the drug was subsequently also approved for the treatment of refractory multiple myeloma, a bone marrow malignancy of the B-lymphocyte lineage. The purpose of this study is to report a case of MDS del(5q) in a female patient, which was most likely secondary to the immunosuppressive drugs that the patient was taking for scleritis. After lenalidomide treatment, the patient's haematological symptoms rapidly resolved and she became transfusion independent, with normal haemoglobin levels. This medication also helped control her dependence on high doses of oral prednisolone. The patient continued to receive treatment with low-dose lenalidomide, and her scleritis has been in long-term remission for 3 years. A larger prospective study can further define the role of lenalidomide in the management of scleritis.

    Full Text Available Diffuse Large B-cell Lymphomas (DLBCL are the most frequent Non-Hodgkin Lymphomas (NHL. The addition of Rituximab to the standard chemotherapy CHOP improved the outcome in this patients, but so far 40% of patients experienced relapse or progressive disease. Lenalidomide, an immunomodulatory agent, had direct tumoricidal and antiangiogenetic actions on tumor cells and was able to modulate tumor-cell microenvironment, with the restoration of impaired T-cell activity and the formation of immuno-synapsis. Based on these actions, lenalidomide represented an active drug on aggressive relapsed NHL. In this review, the most relevant clinical trials for the use of lenalidomide in DLBCL were reported. Monotherapy with lenalidomide showed an activity in term of overall response rate, with acceptable hematological and extrahematological toxicities in relapsed/refractory aggressive NHL. The role of lenalidomide as salvage therapy in both cell of origin patterns in DLBCL (germinal center B-cell/activated B-cell was reported in preliminary data. Preliminary data regarding the role of lenalidomide in addition to chemoimmunotherapy (R-CHOP in first line clinical trials were discussed; data of safety, feasibility and efficacy were promising.

    Background Daratumumab showed promising efficacy alone and with lenalidomide and dexamethasone in a phase 1-2 study involving patients with relapsed or refractory multiple myeloma. Methods In this phase 3 trial, we randomly assigned 569 patients with multiple myeloma who had received one or more previous lines of therapy to receive lenalidomide and dexamethasone either alone (control group) or in combination with daratumumab (daratumumab group). The primary end point was progression-free survival. Results At a median follow-up of 13.5 months in a protocol-specified interim analysis, 169 events of disease progression or death were observed (in 53 of 286 patients [18.5%] in the daratumumab group vs. 116 of 283 [41.0%] in the control group; hazard ratio, 0.37; 95% confidence interval [CI], 0.27 to 0.52; P<0.001 by stratified log-rank test). The Kaplan-Meier rate of progression-free survival at 12 months was 83.2% (95% CI, 78.3 to 87.2) in the daratumumab group, as compared with 60.1% (95% CI, 54.0 to 65.7) in the control group. A significantly higher rate of overall response was observed in the daratumumab group than in the control group (92.9% vs. 76.4%, P<0.001), as was a higher rate of complete response or better (43.1% vs. 19.2%, P<0.001). In the daratumumab group, 22.4% of the patients had results below the threshold for minimal residual disease (1 tumor cell per 10(5) white cells), as compared with 4.6% of those in the control group (P<0.001); results below the threshold for minimal residual disease were associated with improved outcomes. The most common adverse events of grade 3 or 4 during treatment were neutropenia (in 51.9% of the patients in the daratumumab group vs. 37.0% of those in the control group), thrombocytopenia (in 12.7% vs. 13.5%), and anemia (in 12.4% vs. 19.6%). Daratumumab-associated infusion-related reactions occurred in 47.7% of the patients and were mostly of grade 1 or 2. Conclusions The addition of daratumumab to lenalidomide and

    Prednisone is a well-established treatment option in rheumatoid arthritis. Low-dose glucocorticoid therapy alleviates disease signs and symptoms, is better tolerated than high-dose therapy, and its addition to disease-modifying anti-rheumatic drugs (DMARDs) inhibits radiographic disease progression. A low-dose, modified-release (MR) formulation of prednisone, administered in the evening, was developed to counter the circadian rise in pro-inflammatory cytokine levels that contributes to disease activity. In a 12-week, randomized trial (CAPRA-2) in adult patients with rheumatoid arthritis who were receiving stable DMARD therapy, the addition of MR prednisone reduced disease signs and symptoms by ≥20 % according to the American College of Rheumatology criteria (in 48 % of patients vs. 29 % with placebo; p prednisone to stable DMARD therapy reduced the mean duration of morning stiffness to a greater extent than addition of morning immediate-release (IR) prednisone (22.7 vs. 0.4 %; p = 0.045 [primary endpoint]). The improvement in morning stiffness with MR prednisone was maintained for 9-12 months during the open-label extension of CAPRA-1. These findings were supported by data from observational studies in various adult populations with rheumatoid arthritis. Treatment with evening MR prednisone for up to 12 months was generally well tolerated, with an overall similar tolerability profile compared with evening placebo or morning IR prednisone, and no new safety concerns. MR prednisone was estimated to be cost effective relative to IR prednisone in patients with rheumatoid arthritis in a UK pharmacoeconomic model.

Risk stratification, using different prognostic scores and markers, is at the core of MDS management. Deletion 5q [del(5q] MDS is a distinct class of MDS characterized by the haploinsufficiency of specific genes, microRNAs, and proteins, which has been linked to increased sensitivity to the drug lenalidomide. Phase II and III clinical trials have demonstrated the efficacy of lenalidomide in improving clinical outcomes of patients with del(5q MDS, including reduction in red blood cell transfusion requirements and improvements in quality of life. Lenalidomide has also demonstrated some activity in non-del(5q lower-risk MDS as well as higher-risk MDS, especially in combination with other agents. In this paper, we review the pathogenesis of del(5q MDS, the proposed mechanisms of action of lenalidomide, the major clinical trials that documented the activity of lenalidomide in different MDS populations, potential predictors of benefit from the drug and suggested mechanisms of resistance, and the use of combination strategies to expand the clinical utility of lenalidomide in MDS.

    Corticosteroids are essential for life and an integral part of the stress response. However, in excess, corticosteroids can be associated with a variety of effects on the brain including hippocampal atrophy and even neuronal death, mood changes, and declarative memory impairment. The magnitude of mood change in patients receiving prednisone is reportedly associated with previous lifetime corticosteroid exposure, consistent with a sensitization or kindling process whereby greater effects are observed with repeated exposure. To our knowledge, the effect of multiple corticosteroid exposures on mood and memory has not been previously examined prospectively in animals or humans. In this study, 30 human volunteers, with no history of systemic prescription corticosteroid therapy, were given (in random order using a crossover design) two 3-day exposures of prednisone (60 mg/day) and one of identical placebo, with 11-day washouts between each medication exposure. Before and after each 3-day prednisone/placebo exposure, declarative memory was assessed using different versions of the Rey Auditory Verbal Learning Test (RAVLT) to minimize practice or learning effects, while mood was assessed with the 21-item Hamilton Rating Scale for Depression, Young Mania Rating Scale and Internal State Scale. No significant mood changes were found. However, a significant decrease in aspects of RAVLT performance was observed after the first prednisone exposure consistent with a decline in declarative memory performance. The decline in RAVLT performance was significantly smaller after the second prednisone exposure as compared to the initial prednisone exposure. Thus, a second prednisone exposure was associated with an attenuated prednisone-effect on declarative memory. These data suggest tolerance or habituation, rather than sensitization, to prednisone effects on declarative memory during a second exposure. Implications and possible explanations for the findings are discussed.

  14. Lenalidomide in the Treatment of Chronic Lymphocytic Leukemia

    2012-01-01

    Full Text Available The application of nucleoside analogue-based chemotherapy and immunotherapy with rituximab or alemtuzumab has increased both response rate and survival in patients with Chronic Lymphocytic Leukemia (CLL. However, because none of these therapies is curative, sequential therapeutic regimens are required. The majority of patients with relapsed or refractory CLL carry poor prognostic factors and show shorter overall survival and resistance to standard treatment. Numerous drugs have recently been approved for CLL therapy and many novel agents are under clinical investigation. The role of the tumor microenvironment and of immune dysfunction in CLL have allowed to enlarge the therapeutic armamentarium for CLL patients. This article will provide a comprehensive summary regarding mechanism of action, efficacy and safety of lenalidomide in CLL patients. Relevant clinical trials using lenalidomide alone or in combinations are discussed. Lenalidomide shows good activity also in relapsed/refractory or treatment-naive CLL patients. Definitive data from ongoing studies are needed to validate overall and progression-free survival. The toxicity profile might limit lenalidomide use because it can result in serious side effects, but largely controlled by gradual dose escalation. Further understanding of the exact mechanism of action in CLL will allow more efficacious use of lenalidomide alone or in combination regimens.

    Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing prednisone are reviewed. Due to insufficient data prednisone cannot be definitively classified according to the current Biopharmaceutics Classification System (BCS) criteria as both the solubility and the permeability of prednisone are on the borderline of the present criteria of BCS Class I. Prednisone's therapeutic indications and therapeutic index, pharmacokinetics and the possibility of excipient interactions were also taken into consideration. Available evidence indicates that a biowaiver for IR solid oral dosage forms formulated with the excipients tabulated in this article would be unlikely to expose patients to undue risks.

    Prednisone is an old and very valuable drug in clinical use for over 60 years by now. It is well known by physicians and widely used for different kinds of inflammatory states including rheumatoid arthritis (RA). Clinical trials during the last 20 years have changed its clinical use, particularly with regards to dosage. Today, rheumatologists are treating their patients much more likely over a long period of time using a low-dose scheme. The effectiveness and safety of this low-dose use is the objective of the current clinical research and shall be enlightened in this drug profile. It is also featuring current knowledge about the value of modified-release prednisone with regards to the just published results of the 2nd Circadian Administration of Prednisone in Rheumatoid Arthritis trial. Moreover, the mechanisms of action of prednisone and its relatives will be summed up.

    Signalling through the interleukin (IL)-6 pathway induces proliferation and drug resistance of multiple myeloma cells. We therefore sought to determine whether the IL-6-neutralizing monoclonal antibody siltuximab, formerly CNTO 328, could enhance the activity of melphalan, and to examine some of the mechanisms underlying this interaction. Siltuximab increased the cytotoxicity of melphalan in KAS-6/1, INA-6, ANBL-6, and RPMI 8226 human myeloma cell lines (HMCLs) in an additive-to-synergistic manner, and sensitized resistant RPMI 8226.LR5 cells to melphalan. These anti-proliferative effects were accompanied by enhanced activation of drug-specific apoptosis in HMCLs grown in suspension, and in HMCLs co-cultured with a human-derived stromal cell line. Siltuximab with melphalan enhanced activation of caspase-8, caspase-9, and the downstream effector caspase-3 compared with either of the single agents. This increased induction of cell death occurred in association with enhanced Bak activation. Neutralization of IL-6 also suppressed signalling through the phosphoinositide 3-kinase/Akt pathway, as evidenced by decreased phosphorylation of Akt, p70 S6 kinase and 4E-BP1. Importantly, the siltuximab/melphalan regimen demonstrated enhanced anti-proliferative effects against primary plasma cells derived from patients with myeloma, monoclonal gammopathy of undetermined significance, and amyloidosis. These studies provide a rationale for translation of siltuximab into the clinic in combination with melphalan-based therapies.

    To assess the effectiveness and safety of a protocol using medium doses of prednisone to treat lupus nephritis. Patients receiving the 'Cruces-protocol cohort' (CPC) were paired 1:2 with patients from the 'historic cohort' (HC). The CPC received medium doses of prednisone combined with methyl-prednisolone pulses, hydroxychloroquine and immunosuppressive drugs, usually cyclophosphamide. The HC received cyclophosphamide and high-dose prednisone. Partial and complete remission rates and glucocorticoid-related toxicity were assessed. 15 CPC and 30 HC patients were analysed. The mean (SD) initial dose of prednisone was 22 (8) mg/d in the CPC vs. 49 (19) mg/d in the HC (p<0.001). The 6-month mean (SD) cumulative dose of prednisone was 1.7 (0.5) g (average daily dose 9mg) vs. 4.5 (2.1) g (average daily dose 25mg), respectively (p<0.001). The median cumulative dose of cyclophosphamide at six months was 3 (0-4.5) g in the CPC vs. 5 (0-16.8) in the HC (p<0.001). 15/15 (100%) vs. 10/30 (33%) patients were treated with hydroxychloroquine (p<0.001). At six months, 12/15 (80%) patients in the CPC achieved partial or complete remission vs. 14/30 (47%) in the HC (p=0.015). At 12months, 13/15 (87%) vs. 19/30 (63%) patients, respectively, were in complete or partial remission (p=0.055). Toxicity attributable to glucocorticoids was observed in 1/15 (7%) vs. 20/30 (67%) patients, respectively (p<0.0001). A combination of medium-dose prednisone, methylprednisolone pulses, cyclophosphamide and hydroxychloroquine is at least as effective in achieving remission of lupus nephritis as regimes containing high-dose prednisone and causes less toxicity. © 2013.

    Lenalidomide and its analogs, thalidomide and pomalidomide, specifically inhibit growth of mature B-cell lymphomas, including multiple myeloma, and induce interleukin-2 (IL-2) release from T cells. We recently found that this results from activation of the CRBN-CRL4 E3 ubiquitin ligase to degrade the lymphoid transcription factors IKZF1 (Ikaros) and IKZF3 (Aiolos).

    Full Text Available The immunomodulatory agent, lenalidomide, is a structural analogue of thalidomide approved by the US Food and Drug Administration for the treatment of myelodysplastic syndrome (MDS and multiple myeloma (MM. This agent is also currently under active investigation for the treatment of chronic lymphocytic leukemia (CLL and non-Hodgkin’s lymphoma (NHL, as well as in drug combinations for some solid tumors and mantle cell lymphoma (MCL. Although treatment with lenalidomide has translated into a significant extension in overall survival in MM and MDS and has superior safety and efficacy relative to thalidomide, the mechanism of action as it relates to immune modulation remains elusive. Based on preclinical models and clinical trials, lenalidomide, as well as other structural thalidomide derivatives, enhances the proliferative and functional capacity of T-lymphocytes and amplifies costimulatory signaling pathways that activate effector responses and suppress inflammation. This paper summarizes our current understanding of T- and natural killer (NK cell pathways that are modified by lenalidomide in hematopoietic neoplasms to inform future decisions about potential combination therapies.

    2015-06-01

    Lenalidomide (LEN) is an immunomodulatory drug with US Food and Drug Administration approval for use in myelodysplastic syndromes (MDS), multiple myeloma (MM), and mantle cell lymphoma (MCL). The toxicity profile for LEN is similar across indications, with the most common adverse events reported in registration trials being hematologic in nature, and Grade ≥ 3 hematologic toxicities the most common reasons for treatment interruption or permanent LEN discontinuation. However, an analysis of the Celgene Global Drug Safety database showed that nonserious rash was the leading cause of permanent early discontinuation of LEN in patients with MDS treated in the postmarketing setting (similar data not available for patients with MM or MCL). In registration trials, rash was reported in up to a third of patients, but Grade ≥ 3 rash was uncommon and rash rarely led to LEN treatment interruption or permanent discontinuation. This suggests differences in management of LEN-related rash in clinical trials versus real-world use. Most LEN-related rash is mild to moderate in severity and might present as patchy, raised, macular skin lesions, sometimes with localized urticaria, which might be associated with pruritus. Mild to moderate rash might be treated with topical corticosteroids and/or oral antihistamines. Any grade LEN-related rash should be appropriately managed through awareness of symptoms, appropriate and prompt intervention, and maximizing patient self-reporting of early signs of rash using upfront educational initiatives. This guide to management of LEN-related rash reviews key clinical data from registration trials, and the incidence and physiology of LEN-related rash, grading of rash, and guidelines for patients and caregivers.

    Clinical trials of vorinostat, a Class I/II histone deacetylase inhibitor, in combination with proteasome inhibitors and immunomodulatory agents have shown activity in relapsed/refractory multiple myeloma. This phase IIb, open-label, single-institution study evaluated the efficacy of vorinostat in combination with lenalidomide and dexamethasone in lenalidomide-refractory patients. Patients were considered lenalidomide-refractory if they had no clinical response (lenalidomide-containing regimen (lenalidomide non-responsive) or if they had progressive disease on or within 60 days of discontinuing a previous lenalidomide-containing regimen (lenalidomide relapsed/refractory). Patients received oral vorinostat 400 mg days 1-7 and 15-21, lenalidomide 25 mg days 1-21, and dexamethasone 40 mg days 1, 8, 15 and 22 in 28-day cycles. Twenty-five patients were enrolled, median age was 65 years and patients had received a median of 5 prior regimens. The overall response rate was 24% (6 partial responses) and clinical benefit rate (≥stable disease) was 80%. Median time to a partial response was 1·9 months and median duration of response was 3·3 months. Median progression-free survival was 5·3 months. Most common grade 3/4 adverse events were neutropenia (48%), thrombocytopenia (32%), anaemia (20%) and gastrointestinal toxicities (16%). In this heavily pre-treated population, vorinostat in combination with lenalidomide and dexamethasone was active in lenalidomide-refractory patients.

    Full Text Available Lenalidomide is a synthetic compound derived by modifying the chemical structure of thalidomide. It belongs to the second generation of immunomodulatory drugs (IMiDs and possesses pleiotropic properties. Even if lenalidomide has been shown to be active in the treatment of several hematologic malignancies, this review article is mostly focalized on its mode of action in multiple myeloma. The present paper is about the direct and indirect antitumor effects of lenalidomide on malignant plasmacells, bone marrow microenvironment, bone resorption and host’s immune response. The molecular mechanisms and targets of lenalidomide remain largely unknown, but recent evidence shows cereblon (CRBN as a possible mediator of its therapeutical effects.

    Lenalidomide is a second-generation immunomodulatory drug that has been approved to treat relapsed or refractory multiple myeloma. Here, we describe a patient who was treated with a low dose of lenalidomide (5 mg/day on days 1-21 of a 28-day cycle) because the standard dose of bortezomib was too toxic and adverse events persisted. However, he developed fever, dyspnea, hypoxia and pulmonary infiltrates. The results of an extensive workup for other causes including infections were negative and the final diagnosis was lenalidomide-induced interstitial pneumonitis. This is the first case report of lenalidomide-induced pneumonitis in a Japanese patient.

    Lenalidomide induces in patients with myelodysplastic syndrome (MDS) and del(5q) erythroid and cytogenetic response rates as high as 75% and 50%, respectively. It is still unclear, however, how long lenalidomide treatment should be continued and whether or not the drug could be interrupted. To assess the feasibility of lenalidomide discontinuation, we revised a cohort of 16 low-risk MDS patients with del(5q) treated at our institute in a phase II multicentric Italian study. Among the 12 responding patients, four discontinued lenalidomide while in complete response. All four patients needed during treatment a permanent lenalidomide reduction from 10 to 5 mg/day because of haematological toxicity (three patients) or grade 3 muscular and bone pain (one patient). At lenalidomide discontinuation after 16, 20, 27 and 20 months from the start, respectively, all four patients were in complete hematologic response and three forth in complete cytogenetic response. Three patients are still in response after 36, 30 and 20 months from lenalidomide discontinuation, respectively: The remaining patient relapsed after 20 months, and she is now receiving a new course of lenalidomide. In conclusion, long-lasting remissions are achievable in MDS patients with del(5q) in complete response after lenalidomide discontinuation.

Lenalidomide is an oral immunomodulatory drug (IMiD) approved in the United States for patients with MM. Although the introduction of lenalidomide combined with dexamethasone (Len/Dex) has improved the outcome of patients with relapsed/refractory multiple myeloma (RRMM), it is a common knowledge that lenalidomide has been linked to the development of secondary primary malignancies in the MM patients, especially in those who use lenalidomide as a maintenance therapy. In the published literature, these are also many cases reported by clinicians in different secondary primary malignancies after the diagnosis of MM treated with lenalidomide. In this present article, we provided our patient who was identified nasopharyngeal carcinoma (NPC) 46 months after the diagnosis of MM and 21 months after lenalidomide treatment. To the best of our knowledge, this is the first case report related to the occurrence of NPC in a patient with MM after treatment by lenalidomide. Although it is not very sure that the incidence of NPC was associated with the use of lenalidomide, we clinicians should pay adequate attention to this phenomenon in the clinical processing. And much more cooperative studies of large numbers of MM patients are needed to evaluate a possible association between lenalidomide and NPC.

    Ninety-four patients were entered in a clinical trial assessing the clinical activity of cyclophosphamide, doxorubicin, and prednisone (CAP) versus a combination of cyclophosphamide. 5-Fluorouracil, and prednisone (CFP) in patients with advanced breast cancer. Objective response rates were comparable, 49% for CFP and 46% for CAP. There was no statistical difference between the duration of response of the two regimens or in time to progression. Most importantly, survival differences were not apparent. Both regimens were clinically tolerable and toxicities, for the most part, were comparable. Thus, no therapeutic advantage existed for either of these polychemotherapy regimens in patients with advanced breast cancer.

    A multicenter comparative study was carried out to investigate the efficacy and safety of hematopoietic stem cell transplantation with conditioning regimens containing melphalan in pediatric patients with acute lymphoblastic leukemia. One hundred twenty three patients at a variety of remission stages were eligible for study participation. Eighty-nine were transplanted with allogeneic grafts and 34 patients with autologous grafts (23 cases with bone marrow and 11 cases with peripheral blood stem cells). Conditioning regimens used were as follows: melphalan and busulfan for 40 patients, melphalan, busulfan and TBI for 44 patients, other regimens for 39 patients. To accelerate engraftment G-CSF (lenograstim) was administered as a 1-hour or 24-hour drip infusion daily at 5 {mu}g/kg from day 5 until hematological recovery. The five year disease free survival (DFS) was 63% for 42 patients at CR1, 41% for 41 patients at CR2 and 33% for 40 patients at other stages. There was no significant difference in the DFS between allogeneic-transplantation and autologous-transplantation in all disease stages. In patients at remission stage for CR1 and CR2, the 5-year DFS by conditioning regimen was 63% for regimen with melphalan and busulfan, 54% for regimen with melphalan, busulfan and TBI and 54% for regimens with melphalan and TBI. There was no significant difference in the DFS between the groups. Serious complications such as renal failure were observed in 11%, veno-occlusive disease in 9%, and interstitial pneumonia in 9%. The most dominating cause of death was relapse in the disease (48% of deaths) which was most commonly observed in autologous transplantation. Contrary to that, treatment related toxic death was the most frequent cause of deaths in allogeneic-transplantation. (author)

    This study combined infusional mitoxantrone with bolus melphalan as a transplant preparative regimen for multiple myeloma. Mitoxantrone was infused over 6 hr on days 6 and 5. Melphalan was given as a 15 min bolus on day 1 followed by autologous transplant on day 0. Thirty-five patients were enrolled; 57% of enrollees had received ≥ 2 prior treatments. The median overall survival was 5 years and 8 months, with 37% of the subjects alive >7 years posttransplantation. Myelosuppression and mucositis were the most frequent adverse events. This regimen is well tolerated and the survival compares well to other transplant trials.

    No survival advantage of autologous stem cell transplantation (ASCT) has been documented for patients older than 65 years, and in the era of thalidomide (Thalomid), bortezomib (Velcade), and lenalidomide (Revlimid), ASCT has a diminished role in the front-line treatment of older patients with myeloma. For these individuals and for those who cannot or choose not to undergo ASCT, the initial treatment regimens now recommended by both the National Comprehensive Cancer Network and the International Myeloma Working Group are melphalan (Alkeran)/prednisone/thalidomide (MPT), bortezomib/melphalan/prednisone (VMP), and lenalidomide/low-dose dexamethasone. Melphalan/prednisone should no longer be considered the reference treatment, although it may be appropriate for a small number of patients with serious comorbidity and/or poor performance status. Advantages of VMP over MPT include rapid response, high rates of complete response, patient compliance, and more extensive evidence of efficacy in patients with certain cytogenetic abnormalities. Lenalidomide/low-dose dexamethasone is particularly appropriate for patients with preexisting neurotoxicity and those who wish to postpone ASCT. Toxicity profiles differ among the newly established and emerging regimens, and oncology teams must take care to apply the appropriate risk management measures, including dose reduction where necessary.

    Thalidomide and the immunomodulatory drug, lenalidomide, are therapeutically active in hematological malignancies. The ubiquitously expressed E3 ligase protein cereblon (CRBN) has been identified as the primary teratogenic target of thalidomide. Our studies demonstrate that thalidomide, lenalidomide and another immunomodulatory drug, pomalidomide, bound endogenous CRBN and recombinant CRBN-DNA damage binding protein-1 (DDB1) complexes. CRBN mediated antiproliferative activities of lenalidomide and pomalidomide in myeloma cells, as well as lenalidomide- and pomalidomide-induced cytokine production in T cells. Lenalidomide and pomalidomide inhibited autoubiquitination of CRBN in HEK293T cells expressing thalidomide-binding competent wild-type CRBN, but not thalidomide-binding defective CRBN(YW/AA). Overexpression of CRBN wild-type protein, but not CRBN(YW/AA) mutant protein, in KMS12 myeloma cells, amplified pomalidomide-mediated reductions in c-myc and IRF4 expression and increases in p21(WAF-1) expression. Long-term selection for lenalidomide resistance in H929 myeloma cell lines was accompanied by a reduction in CRBN, while in DF15R myeloma cells resistant to both pomalidomide and lenalidomide, CRBN protein was undetectable. Our biophysical, biochemical and gene silencing studies show that CRBN is a proximate, therapeutically important molecular target of lenalidomide and pomalidomide.

    Lenalidomide is manageable and effective in multiple myeloma, particularly in elderly patients. Surprisingly, the combination of lenalidomide with rituximab produced clinically significant anemia at 25 mg/day for 21/28 days, the highest possible dose, in Waldenström's Macroglobulinemia (WM). We aimed to determine the maximum tolerated dose (MTD) of single agent lenalidomide and determine its impact on WM. RV-WM-0426 is a multicenter dose escalation open label phase 1/2 study of lenalidomide in relapsed/refractory WM (RRWM). Lenalidomide was given orally 21/28 days per cycle for 1 year, at escalated dose of 15 to 20 mg during phase 1 to determine the MTD; the phase 2 part was conducted at the MTD. Seventeen RRWM patients were included. The MTD was established at 15 mg/day 21/28. By ITT analysis, the overall response rate was 29%. With a median follow-up of 36 months, median TTP was 16 months (95% CI 5.5-26), the 5-year OS was 91%. The most frequent adverse events ≥ grade 3 at 15 mg were 14% anemia and 43% neutropenia. The MTD of lenalidomide is 15 mg/day 21/28 days in RRWM. Lenalidomide is active in the treatment of RRWM and the safety profile appears manageable. Future studies may look into combinations of lenalidomide and continuous dosing.

    Full Text Available Corticosteroids and melphalan were used for decades to treat multiple myeloma. Combination chemotherapy has been extensively studied with similar overall survival rates to melphalan and prednisone. In the last decade, the development of new agents has progressed significantly. Thalidomide and its newer derivatives lenalidomide, bortezomib, and pegylated liposomal doxorubicin have drastically revolutionized treatment approaches. As a result, numerous clinical trials have yielded exciting treatment strategies resulting in therapeutic advances, and improved responses and overall survival of patients. This review summarizes the international uniform response criteria for multiple myeloma and gives a historical perspective on previous therapies with updates on the newest available treatments.

    All immunoregulatory chemotherapeutics are chiefly applied in a systemic setting for anticancer therapy. However, immune responses following loco-regional application of chemotherapy may differ from those after systemic application. We recently found that Melphalan, a prototypical loco-regionally applied chemotherapeutic agent, exhibits the ability to increase the immunogenicity of dying melanoma cells.

    Melphalan is associated with severe side effects such as mucositis, diarrhea, and myelosuppression. We investigated how much the individual severity of these side effects is predicted by pharmacokinetics. In addition, we studied glutathione S-transferase GSTM1, GSTT1, and GSTP1 polymorphisms in relation to adverse events. A high interindividual pharmacokinetic variability was observed in 84 patients. There was a linear correlation between creatinine and melphalan clearance (P=0.0004). Patients treated with a dose > or = 70 mg/m(2) had a 23-fold increased risk to develop mucositis (P<0.001) and a 12-fold increased risk to develop diarrhea (P<0.001) compared with lower doses. The GSTP1 codon 105 polymorphism may be relevant for development of mucositis and the GSTT1 deletion may predict diarrhea, but these findings require confirmation. Melphalan-induced side effects were significantly dependent only on dose. Therapeutic drug monitoring or genotyping for GST does not appear to be very helpful in optimizing therapy with melphalan.

    We investigated the mechanisms of action of immuno-modulatory drug (lenalidomide) on the protein expression of cereblon (CRBN) and their therapeutic targets in the multiple myeloma cell line RPMI8226. The multiple myeloma cell line RPMI8226 was cultured and treated with different concentrations of lenalidomide and bortezomib to determine the proliferation inhibition rate, apoptosis rate, and protein expression of CRBN. The results revealed that both lenalidomide and bortezomib inhibited the proliferation of RPMI8226 and promoted cell apoptosis. However, the protein expression of CRBN decreased signifi-cantly after treatment with lenalidomide, while bortezomib had no effect on the expression of CRBN. We confirmed that CRBN may be a target of lenalidomide.

    Lenalidomide is a drug with clinical efficacy in multiple myeloma and other B cell neoplasms, but its mechanism of action is unknown. Using quantitative proteomics, we found that lenalidomide causes selective ubiquitination and degradation of two lymphoid transcription factors, IKZF1 and IKZF3, by the CRBN-CRL4 ubiquitin ligase. IKZF1 and IKZF3 are essential transcription factors in multiple myeloma. A single amino acid substitution of IKZF3 conferred resistance to lenalidomide-induced degradation and rescued lenalidomide-induced inhibition of cell growth. Similarly, we found that lenalidomide-induced interleukin-2 production in T cells is due to depletion of IKZF1 and IKZF3. These findings reveal a previously unknown mechanism of action for a therapeutic agent: alteration of the activity of an E3 ubiquitin ligase, leading to selective degradation of specific targets.

    Lenalidomide (REVLIMID), an immunomodulatory compound targeting both cancer cells and their microenvironment, has substantial activity in several difficult-to-manage hematological malignancies. In previously treated multiple myeloma, lenalidomide produces high-quality responses combined with sustained disease control. Recently, several randomized studies have demonstrated a clinical benefit of continuous lenalidomide treatment in newly diagnosed multiple myeloma. In many patients with refractory anemia associated with lower risk myelodysplastic syndromes and a 5q chromosome deletion, lenalidomide leads to transfusion independence, considerably improving quality of life. It has a manageable safety profile, and its oral formulation reduces the burden on patients. Several phase III trials are ongoing in other indications currently underserved by conventional therapy, such as chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and prostate cancer. Several early-stage studies are exploring lenalidomide alone and in combination across different hematological malignancies, solid tumors, and immune-related disorders.

Material and methods: Our retrospective epidemiological study was based on claims data of the year 2007 from four statutory health insurances with more than 14 million enrollees. Annual incidence was calculated by dividing the total number of new lenalidomide users by the sum of person-years of the at-risk population. Potential off-label use was identified by an algorithm searching for a diagnosis of multiple myeloma in the quarter of the lenalidomide prescription and the four preceding quarters. Results: In 2007, 235 lenalidomide users were identified. Incidence of lenalidomide use was 4.0 per 100,000 person years (95% CI: 3.5–4.5. In 40 (17.0% users of lenalidomide, no diagnosis of multiple myeloma was found. Of the 40 off-label users, 29 (72.5% had a diagnosis of MDS.

    Lenalidomide in combination with dexamethasone is an effective and well-established treatment of relapsed or refractory multiple myeloma (rrMM) disease. Due to the scarcity of reports assessing benefit and risk of long-term lenalidomide treatment in non-selected rrMM patients, we retrospectively analysed the long-term outcome in patients with rrMM treated with lenalidomide and dexamethasone. Sixty-seven patients (pts) who were treated with lenalidomide/dexamethasone for rrMM in the approved indication from 2007 to 2011 were included in this retrospective, single-centre analysis. Kaplan-Meier survival estimates were compared between total population, patients on lenalidomide for more than 12 months (mo) and patients discontinuing therapy earlier than 12 months. Median overall survival (OS) of the total patient population was 33.2 mo. OS of pts treated beyond 12 mo was 42.9 mo compared to 20.2 mo (p = 0.027) for pts stopping lenalidomide earlier than 12 mo for other reasons than progression disease (PD). OS of pts >12 mo on lenalidomide treatment did not significantly differ between pts who had received previous autologous transplantation, allogeneic transplantation or conventional therapy. Main non-hematologic toxicities were infections of grade 3/4 in 25 % and thrombembolic events of all grades in 18 % of patients. To the best of our knowledge, this is the first report on feasibility and efficacy of long-term lenalidomide treatment in a non-selected patient cohort. OS of pts >12 mo on lenalidomide is superior when compared to pts discontinued earlier for reasons other than PD. Our data confirm the current use of lenalidomide as a continuous long-term treatment strategy.

    In a subset of patients with non-del(5q) myelodysplastic syndrome (MDS), lenalidomide promotes erythroid lineage competence and effective erythropoiesis. To determine the mechanism by which lenalidomide promotes erythropoiesis, we investigated its action on erythropoietin receptor (EpoR) cellular dynamics. Lenalidomide upregulated expression and stability of JAK2-associated EpoR in UT7 erythroid cells and primary CD71+ erythroid progenitors. The effects of lenalidomide on receptor turnover were Type I cytokine receptor specific, as evidenced by coregulation of the IL3-Rα receptor but not c-Kit. To elucidate this mechanism, we investigated the effects of lenalidomide on the E3 ubiquitin ligase RNF41. Lenalidomide promoted EpoR/RNF41 association and inhibited RNF41 auto-ubiquitination, accompanied by a reduction in EpoR ubiquitination. To confirm that RNF41 is the principal target responsible for EpoR stabilization, HEK293T cells were transfected with EpoR and/or RNF41 gene expression vectors. Steady-state EpoR expression was reduced in EpoR/RNF41 cells, whereas EpoR upregulation by lenalidomide was abrogated, indicating that cellular RNF41 is a critical determinant of drug-induced receptor modulation. Notably, shRNA suppression of CRBN gene expression failed to alter EpoR upregulation, indicating that drug-induced receptor modulation is independent of cereblon. Immunohistochemical staining showed that RNF41 expression decreased in primary erythroid cells of lenalidomide-responding patients, suggesting that cellular RNF41 expression merits investigation as a biomarker for lenalidomide response. Our findings indicate that lenalidomide has E3 ubiquitin ligase inhibitory effects that extend to RNF41 and that inhibition of RNF41 auto-ubiquitination promotes membrane accumulation of signaling competent JAK2/EpoR complexes that augment Epo responsiveness.

    We have previously found that ex vivo expanded human CD4(+)CD25(+)Treg cells suppress proliferation of lymphoma B-cell lines. Here we demonstrate that the immunomodulatory drug lenalidomide potentiates suppression of lymphoma B-cell proliferation by freshly isolated CD4(+)CD25(+)Tregs, as well as suppression by Tregs expanded polyclonally in the presence of rapamycin from CD4(+)CD25(+)T cells or CD4(+)CD25(+)CD127(lo)T cells. The regulation of lymphoma cell proliferation by Tregs pre-expanded with "third-party" allogeneic MoDCs in the presence of rapamycin was also potentiated by lenalidomide. Lenalidomide contributed to the suppression exerted by Tregs despite concomitant downregulation of Treg proliferation. Lenalidomide did not reduce the suppression of conventional T cells by expanded Tregs. The exposure of polyclonally expanded Tregs to lenalidomide did not significantly alter their phenotype. There was no uniform pattern of lenalidomide effect on Treg-mediated regulation of lymphoma B cells freshly isolated from patients. Freshly isolated lymphoma cells activated with multimeric CD40L and IL-4 to support their survival in vitro varied in their sensitivity to lenalidomide, and the regulatory effect of Tregs on such lymphoma cells ranged from suppression to help in individual patients. Lenalidomide potentiated or attenuated Treg effects on the survival of freshly isolated lymphoma cells. A combination of lenalidomide treatment with adoptive transfer of CD4(+)CD25(+)Tregs or CD4(+)CD25(+)CD127(lo)Tregs expanded ex vivo could be used to suppress proliferation of residual lymphoma in select patients with lymphoma responsive to the regulation by Tregs and sensitive to lenalidomide.

    Haploidentical transplantation (Haplo-SCT) with post-transplantation cyclophosphamide (PTCy) is increasingly utilized for the treatment of lymphoma and almost exclusively with the nonmyeloablative fludarabine (Flu)/cyclophosphamide/total body irradiation (TBI) conditioning regimen. We present early results of a reduced-intensity (RIC) regimen utilizing fludarabine and melphalan (FM) for the treatment of advanced lymphoma. All patients with a diagnosis of lymphoma or chronic lymphocytic leukemia (CLL) who received Haplo-SCT at the University of Texas MD Anderson Cancer Center between 2009 and 2014 were reviewed (N = 22). Patients received Flu 160 mg/m(2) and melphalan 100 mg/m(2) to 140 mg/m(2) with thiotepa 5 mg/kg or 2 Gy TBI. Because of concerns of increased treatment-related mortality (TRM) with the melphalan 140 mg/m(2) regimen (FM140), a RIC regimen with melphalan 100 mg/m(2) (FM100) was devised. Rituximab was included for CD20(+) disease. Graft-versus-host disease prophylaxis consisted of PTCy 50 mg/kg on days +3 and + 4, tacrolimus, and mycophenolate mofetil. Sixty-eight percent of all patients were not in complete remission at the time of transplantation. The 2-year progression-free survival (PFS) and overall survival (OS) for the entire cohort were 54%, 1-year TRM was 19%, and the cumulative incidence of relapse at 2 years was 27%. Two-year PFS for Hodgkin lymphoma, non-Hodgkin lymphoma, and CLL/small lymphocytic lymphoma were 57%, 51%, and 75%. Patients treated with FM100 compared to FM140 had equivalent PFS (71% versus 37%, P = .246) and OS (71% versus 58%, P = .32). These early results establish Flu and melphalan 100 mg/m(2) with 2 Gy TBI or thiotepa 5 mg/kg as a very promising conditioning regimen for the treatment of advanced lymphoma with Haplo-SCT and PTCy.

    Full Text Available ObjectiveDuchenne muscular dystrophy (DMD is a degenerative disease that usually becomes clinically detectable in childhood as progressive proximal weakness. No cure is yet available for DMD, but the use of steroids improves muscle strength and function. This study has been carried out to select the best steroid for the management of DMD.Materials & MethodsThis study is a single-blind, randomized clinical trial with a sample volume of 34 DMD patients. Half of these patients were treated with deflazacort (0.9 mg/kg daily and the other half with prednisone (0.75 mg/kg daily for a period of 18 months. The motor function score and excess body weight were registered one year after the start and also at the end of the study and compared between the two groups.ResultsDeflazacort was more effective in the improvement of motor function after one year, but there was no significant difference between the two drugs at the end of the study (18 months after start. Weight gain after one year and at the end of the study was higher in prednisone group and steroid treatment with deflazacort appears to cause fewer side effects than prednisone regarding weight gain.ConclusionDeflazacort seems to be more effective than prednisone in the improvement of motor function causing fewer side effects, particularly weight gain. This medication may be important for the improvement of motor function and could be used as the best steroidal treatment for Duchenne muscular dystrophy.

    Full Text Available Systemic lupus erythematosus (SLE is a chronic, multi-system, autoimmune disorder characterized by the production of autoantibodies and immune complexes deposition in tissue. Clinical manifestations may include skin, mucosa, joints, blood, heart, lungs, kidneys, central nervous system (CNS, immune system, and ears. SLE Iin the ears can caused sensorineural hearing loss, tinnitus, and vertigo. This hearing disorder is commonly bilateral and has high frequencies. Prednisone is an oral corticosteroid with glucocorticoid and mineralocorticoid effects. Glucocorticoids have anti-inflammatory and immunosuppressive effects. The aim of this study was to evaluate the effect of prednisone in improving the degree of hearing loss in patients with SLE. This study was conducted in from March–May 2013, at tThe Hearing and Speech Disorder Clinic of Ear Nose Throat-Head and Neck Surgery, Dr. Hasan Sadikin Hospital Bandung, using quasi-experimental method with pre-post design in which the results were statistically calculated using Rank Spearman test. This study involved 28 subjects who had been diagnosed for SLE. Anamnesis, physical examination, and laboratory test were performed, followed by pure tone audiometry, tympanometry, and distortion product optoacoustic emissions (DPOAE. Subjects were given prednisone 1 mg/kgBW/day with a maximum dose of 6o mg/day. Re-evaluation was performed after 4 weeksof treatment. Before treatment, 26 subjects had mild hearing loss and 2 subjects had symmetric moderate hearing loss at high frequencies symmetrically. After therapy, 24 subjects became normal and 4 subjects still had hearing loss (Rs=0.734, p<0.01. In conclusion, prednisone can improve hearing status of SLE patients.

    Melphalan is an alkylating agent frequently used in an intravenous formulation to treat hematologic malignancies and solid tumors in both adults and children. According to the manufacturer, melphalan is stable in sterile 0.9% sodium chloride for 90 min at room temperature (RT). Several authors have studied the stability of different concentrations of melphalan; however, most were not adapted to the current manufacturing process applied in pharmaceutical centralized units. This study was conducted to determine the stability of melphalan in 0.9% sodium chloride solutions at concentrations used for intravenous injection in practice. Melphalan is commonly prepared in diluted solutions ranging from 2 to 4 mg/ml for the treatment of adult patients and at lower concentrations (down to 0.5 mg/ml) for pediatric use. Accordingly, these were the three concentrations chosen for this study. Melphalan concentrations were measured with high-performance thin-layer chromatography (HPTLC). At RT, admixtures prepared at 4 mg/ml were stable for up to 8 h without protection from light; however, at lower concentrations, such as 0.5 and 2 mg/ml, stability did not exceed 2 h. When refrigerated, melphalan was stable for 24 h at 2 mg/ml; however, at 0.5 and 4 mg/ml, the drug was not stable. Melphalan solutions present with limited stability at 0.5, 2, and 4 mg/ml and are not adapted for delayed administration in pharmaceutical centralized units. However, at 4 mg/ml and at RT, a stability of 8 h is very interesting in practice and allows sufficient time for preparation, pharmaceutical control, transport, and administration.

    Thalidomide and lenalidomide are structural analogs and immunomodulatory drugs. Lenalidomide appears to have a different safety profile than thalidomide and could be less toxic, and as far as we know, we did not found any study comparing their safety profile. The objective of our study was to review and compare serious adverse drug reactions (SADRs) of thalidomide and lenalidomide spontaneously reported to the French Pharmacovigilance database. We extracted all medically confirmed spontaneous reports of SADR for lenalidomide-based regimens and thalidomide-based regimens from the French Pharmacovigilance database. A "serious" adverse drug reaction (ADR) was defined as an ADR that is fatal or life threatening, which causes hospitalization or prolongation of hospitalization, or permanent or significant disability. The study period was between marketing of 2 drugs and January 15, 2012. A total of 392 SADRs related to thalidomide-based regimens were identified in 244 patients and 377 SADRs related to lenalidomide-based regimens in 220 patients. In spite of their structural analogy, this study highlights interesting differences between lenalidomide and thalidomide's safety profile: nervous system and vascular disorders are more frequent with thalidomide-based regimens while hematologic, skin, infectious disorders and secondary primary cancers are more frequent with lenalidomide-based regimens.

    Renal failure is a frequent complication of multiple myeloma (MM). Recently, the combination of lenalidomide-dexamethasone has become one of the cornerstone regimens for the treatment of MM. Impairment of renal function exacerbation is a rare, but potential, complication of lenalidomide therapy in plasma cell dyscrasias. We present two patients who developed exacerbation of renal function during their first cycle of therapy with lenalidomide. In the first case, we present a 76-year-old-male with MM and impaired renal function, who declined two weeks after initiation of second-line therapy with lenalidomide. His renal functions improved after discontinuation of lenalidomide and with supportive care. In the second case, we describe a 61-year-old woman who was started on lenalidomide for relapsed MM and admitted to intensive care unit three weeks later due to severe renal failure. Despite intensive supportive care, her renal function deteriorated even more and she died. We conclude that renal failure is an uncommon, but serious, potential complication of lenalidomide therapy in plasma cell dyscrasias, particularly MM. Close monitoring of renal function is clearly recommended during this treatment.

    Lenalidomide is a highly effective treatment for myelodysplastic syndrome (MDS) with deletion of chromosome 5q (del(5q)). Here, we demonstrate that lenalidomide induces the ubiquitination of casein kinase 1A1 (CK1α) by the E3 ubiquitin ligase CUL4-RBX1-DDB1-CRBN (known as CRL4(CRBN)), resulting in CK1α degradation. CK1α is encoded by a gene within the common deleted region for del(5q) MDS and haploinsufficient expression sensitizes cells to lenalidomide therapy, providing a mechanistic basis for the therapeutic window of lenalidomide in del(5q) MDS. We found that mouse cells are resistant to lenalidomide but that changing a single amino acid in mouse Crbn to the corresponding human residue enables lenalidomide-dependent degradation of CK1α. We further demonstrate that minor side chain modifications in thalidomide and a novel analogue, CC-122, can modulate the spectrum of substrates targeted by CRL4(CRBN). These findings have implications for the clinical activity of lenalidomide and related compounds, and demonstrate the therapeutic potential of novel modulators of E3 ubiquitin ligases.

    The objective of the study was to investigate the effects and safety of novel agents such as bortezomib and lenalidomide in the treatment of newly diagnosed patients with multiple myeloma. We performed a comprehensive meta-analysis of randomized controlled trials (RCTs). An initial search yielded 627 citations, of which 10 RCTs enrolling 4534 patients met the inclusion criteria. The addition of bortezomib to first-line therapy significantly prolonged overall survival (OS) (hazard ratio [HR], 0.75 [0.65, 0.87], p lenalidomide had no impact on survival (HR, 0.88 [0.65, 1.20], p = 0.42). Both lenalidomide and bortezomib consistently improved progression-free survival (PFS) compared with conventional therapy alone. The corresponding HRs were 0.65, 95% confidence interval (CI) [0.55, 0.77] (p lenalidomide, respectively. Some of the increased adverse events reported were herpes zoster (relative risk [RR], 3.64 [2.23, 5.94], p lenalidomide. Interestingly, treatment with bortezomib seemed to be associated with a lower rate of treatment related mortality (RR, 0.39 [0.18, 0.85], p = 0.02). An increased incidence of second primary cancers was observed in the lenalidomide group (RR 2.61 [1.60, 4.27], p lenalidomide and bortezomib consistently improved PFS of patients with newly diagnosed myeloma when it was added to standard therapy.

    Lenalidomide activates the immune system, but the exact immunomodulatory mechanisms of lenalidomide in vivo are poorly defined. In an observational study we assessed the impact of lenalidomide on different populations of immune cells in multiple myeloma patients. Lenalidomide therapy was associated with increased amounts of a CD8(+) T cell subset, phenotypically staged between classical central memory T cells (TCM) and effector memory T cells (TEM), consequently termed TCM/TEM. The moderate expression of perforin/granzyme and phenotypical profile of these cells identifies them as not yet terminally differentiated, which makes them promising candidates for the anti-tumour response. In addition, lenalidomide-treated patients showed higher abundance of CD14(+) myeloid cells co-expressing CD15. This population was able to inhibit both CD4(+) and CD8(+) T cell proliferation in vitro and could thus be defined as a so far undescribed novel myeloid-derived suppressor cell (MDSC) subtype. We observed a striking correlation between levels of TCM/TEM, mature regulatory T cells (T(regs)) and CD14(+) CD15(+) MDSCs. In summary, lenalidomide induces both activating and inhibitory components of the immune system, indicating the existence of potential counter-regulatory mechanisms. These findings provide new insights into the immunomodulatory action of lenalidomide.

    New approaches to sterilizing male animals are needed to control captive and wild animal populations. We sought to develop a nonsurgical method of permanent sterilization for male animals by administering the gonadotoxicant melphalan conjugated to peptides derived from the β-chain of FSHβ. We hypothesized that conjugating melphalan to FSHβ peptides would magnify the gonadotoxic effects of melphalan while minimizing systemic toxicity. The ability of conjugates of melphalan and FSHβ peptides to kill murine testicular cells was first tested in vitro in a three-dimensional testicular cell coculture system. In this system, melphalan caused considerable cell death as measured both by increases in lactate dehydrogenase concentrations in the culture supernatant and direct visualization of the cultures. Of the conjugates tested, melphalan conjugated to a 20-amino acid peptide derived from human FSHβ consisting of amino acids 33 to 53 (FSHβ (33-53)-melphalan) was very potent, with cell cytotoxicity and lactate dehydrogenase release roughly one-half that of melphalan. The effects of melphalan and FSHβ (33-53)-melphalan on spermatogenesis were then tested in vivo in mature C56Bl/6 male mice. Four weeks after intraperitoneal injection, all mice treated with either FSHβ (33-53)-melphalan or melphalan had approximately 75% reductions in testicular spermatid counts compared with control animals. Testicular histology revealed significant reduction in mature spermatids and spermatocytes in most tubules. However, 12 weeks after the injection, testicular spermatid counts and histology were similar to controls, except in one animal receiving FSHβ (33-53)-melphalan that had no apparent spermatogenesis. We conclude that melphalan and FSHβ (33-53)-melphalan are potent gonadotoxicants in male mice resulting in marked suppression of spermatogenesis 4 weeks after a single intraperitoneal injection. However, this effect is transient in most mice as spermatogenesis is similar to

    As multiple myeloma (MM) progresses, natural killer (NK)-cell responses decline against malignant plasma cells. The immunomodulatory drug lenalidomide is widely used for treatment of MM but its influence on NK-cell biology is unclear. Here, we report that lenalidomide lowers the threshold for NK-cell activation, causing a 66% decrease in the 50% effective concentration (EC50) for activation through CD16, and a 38% decrease in EC50 for NK group 2 member D (NKG2D)-mediated activation, allowing NK cells to respond to lower doses of ligand. In addition, lenalidomide augments NK-cell responses, causing a twofold increase in the proportion of primary NK cells producing interferon-γ (IFN-γ), and a 20-fold increase in the amount of IFN-γ produced per cell. Importantly, lenalidomide did not trigger IFN-γ production in unstimulated NK cells. Thus, lenalidomide enhances the NK-cell arm of the immune response, without activating NK cells inappropriately. Of particular clinical importance, lenalidomide also allowed NK cells to be activated by lower doses of rituximab, an anti-CD20 monoclonal antibody (mAb) widely used to treat B-cell malignancies. This supports combined use of lenalidomide and rituximab in a clinical setting. Finally, superresolution microscopy revealed that lenalidomide increased the periodicity of cortical actin at immune synapses, resulting in an increase in the area of the actin mesh predicted to be penetrable to vesicles containing IFN-γ. NK cells from MM patients also responded to lenalidomide in this way. This indicates that nanometer-scale rearrangements in cortical actin, a recently discovered step in immune synapse assembly, are a potential new target for therapeutic compounds.

    Cereblon (CRBN) is essential for the anti-myeloma (MM) activity of immunomodulatory drugs (IMiDs), such as thalidomide and lenalidomide. However, the clinical implications of CRBN in MM patients are unclear. Using immunohistochemical (IHC) staining on paraffin-embedded bone marrow sections, the expression of CRBN protein in myeloma cells (MCs) was assessed in 40 relapsed/refractory MM (RRMM) patients who received lenalidomide/dexamethasone (LD) and 45 and 22 newly diagnosed MM (NDMM) patients who received thalidomide/dexamethasone (TD) and melphalan/bortezomib/prednisolone (MVP), respectively. IHC staining were scored on a scale representing the diffuseness and intensity of positive-staining MCs (range, 0-8) and a score ≥4.5 was used for CRBN positivity (CRBN(+)) on a cut-point analysis of all possible scores and response of TD and LD. Compared to CRBN(+) NDMM patients, CRBN(-) NDMM patients had more international staging system (ISS) III (26 vs. 61 %, respectively; P = 0.006). In the LD and TD cohorts, the response rate (RR) was higher in CRBN(+) patients than CRBN(-) patients (LD 79 vs. 33 %, respectively; P = 0.005) (TD 75 vs. 29 %, respectively; P = 0.005); however, this trend was not observed in the MVP cohort. In the LD and TD cohorts, the positive and negative prediction value of CRBN(+) for treatment response was 79 and 67 % and 75 and 71 %, respectively. Multivariate analysis showed that CRBN(+) was a significant factor associated with superior RR for LD and TD. The data suggest that expression of CRBN protein in MCs assessed using the IHC is a feasible approach to predict the response of IMiDs in MM patients.

    Conventional glucocorticoids exert a negative influence on calcium balance, and long-term treatment with these agents leads to osteopenia. Deflazacort is an oxazoline derivative of prednisolone with documented calcium-sparing properties when compared to prednisone on a weight basis. The purpose...... of the present study was to determine the relative antiinflammatory potency of deflazacort and prednisone.

    Sarcoidosis is a disease which still has uncertain etiology. Possible environmental causes are cited in the literature, like organic and inorganic particles and infectious agents. Recent studies have demonstrated the occurrence of sarcoidosis in patients with chronic C hepatitis; however, this association remains without statistical or causal evidence. In this report a case of sarcoidosis associated with chronic hepatitis C will be described, with subcutaneous lesions, considered rare, and good response to treatment with colchicine and prednisone. The hepatitis C virus was isolated in sarcoid tissue and the association between the two diseases will be discussed. PMID:27192527

    Prednisone, a corticosteroid frequently used to treat common AIDS-related illnesses and comorbidities, has been shown to induce drug metabolism. This study was performed to determine whether prednisone coadministration affected the pharmacokinetics of dolutegravir (DTG). In this open-label, repeat-dose study, 12 healthy subjects were administered DTG at 50 mg daily alone for 5 days and then with concomitant prednisone for 10 days (prednisone at 60 mg daily for 5 days, followed by a 5-day taper). Serial blood sampling and safety assessments were performed during the trial. Pharmacokinetic parameters were determined using noncompartmental methods and geometric least-square mean ratios, and 90% confidence intervals were generated. Coadministration of DTG and 5-day high-dose prednisone with a 5-day taper had a modest effect on DTG exposure. The area under the DTG plasma concentration-time curve, maximum observed DTG concentration, and 24-hour postdose DTG concentration were increased by 11%, 6%, and 17%, respectively, on day 10 of the combination. Similar results were observed after 5 days of DTG and prednisone. Dolutegravir and prednisone coadministration was well tolerated. The changes in plasma exposures of DTG in healthy individuals as a result of prednisone dosing were not clinically significant. No dose adjustment is required for DTG coadministered with prednisone.

    Lenalidomide is an orally active immunomodulatory drug that has direct antineoplastic activity and indirect effects mediated through multiple types of immune cells found in the tumor microenvironment, including B, T, natural killer (NK), and dendritic cells. Recently, the E3 ubiquitin ligase cereblon was identified as a molecular target that may underlie the effects of lenalidomide on tumor cells, as well as on cells in the tumor microenvironment. Decreases in cereblon attenuate these effects and also confer resistance to lenalidomide. Tumoricidal effects of lenalidomide are associated with reduced interferon regulatory factor 4, a downstream target of cereblon. Lenalidomide stimulates proliferation and activation of NK cells, thereby enhancing NK cell-mediated cytotoxicity and antibody-dependent cellular cytotoxicity. These effects appear to be secondary to cytokine production from T cells. Lenalidomide has been shown to produce synergistic effects in experimental models when evaluated in combination with rituximab, dexamethasone, bortezomib, and B-cell receptor signaling inhibitors, consistent with mechanisms complementary to these agents. These experimental findings have translated to the clinic, where single-agent use displays durable responses in relapsed/refractory non-Hodgkin lymphoma, and combination with rituximab and other agents leads to improved responses at first line and in relapsed/refractory disease. The activity of lenalidomide is evident across multiple lymphoma subtypes, including indolent and aggressive forms. The interaction among cell types in the immune microenvironment is increasingly recognized as important to tumor cell recognition and destruction, as well as to protection of normal immune cells, as reflected by lenalidomide studies across multiple types of B-cell lymphomas. © 2015 by American Society of Clinical Oncology.

    Full Text Available BACKGROUND: In recent years, a number of randomized controlled trials (RCTs have reported on lenalidomide as a treatment for multiple myeloma (MM. Herein, we report results of a meta-analysis of RCTs examining the efficacy and safety of lenalidomide for MM. PATIENTS AND METHODS: Databases were searched using the terms "lenalidomide or revlimid AND multiple myeloma."RCTs evaluating initial or maintenance therapeutic outcomes were included. Main outcome measures were response rates, progression-free survival (PFS, overall survival, and adverse events. RESULTS: Seven trials were included (N = 192-614 participants. Lenalidomide doses and treatment regimens differed between trials. Complete response (CR and very good partial response (VGPR risk ratios (RR favored lenalidomide over placebo (CR = 2.54, 95% confidence interval [CI] = 1.29-5.02; VGPR = 2.82, 95% CI = 1.30-6.09. The PFS hazard ratio favored lenalidomide over placebo (0.37, 95% CI = 0.33-0.41. For adverse events, neutropenia, deep vein thrombosis (DVT, infection, and hematologic cancer RR favored placebo over lenalidomide (neutropenia: 4.74, 95% CI = 2.96-7.57; DVT: 2.52; 95% CI: 1.60-3.98; infection: 1.98; 95% CI: 1.50-2.62; hematologic cancer: 3.20; 95% CI: 1.28-7.98. CONCLUSIONS: Lenalidomide is an effective treatment for MM; however, treatment-related adverse events must be considered and appropriate adjustments and/or prophylactic treatment should be initiated where possible.

    Full Text Available Jing Wang, Hongfeng Guo, Xin Zhou Department of Hematology, Wuxi People’s Hospital, Nanjing Medical University, Wuxi, People’s Republic of China Abstract: Multiple myeloma (MM is an incurable hematologic malignancy caused by the autonomous growth of malignant plasma cells. In the last decade, the introduction of novel targeted agents such as thalidomide, bortezomib, and lenalidomide has dramatically improved the clinical outcome of MM patients in both the frontline and recurrent settings. Lenalidomide is a synthetic derivative of thalidomide, which has been shown to significantly improve overall survival, time to progression, and overall response rates in patients with MM. The China Food and Drug Administration approved the use of lenalidomide in patients with MM in 2013. In a Phase II trial, lenalidomide plus low-dose dexamethasone was associated with a high response rate and acceptable safety profile in heavily pretreated Chinese patients with relapsed/refractory MM, including those with renal impairment and IgD subtype. However, lenalidomide will remain as a second-line antimyeloma drug in the near future because of its high price and the policy of health insurance reimbursement in People’s Republic of China. In this review, we summarize the clinical utility and patient considerations in the use of lenalidomide for MM in Chinese patients. Further studies with larger sample sizes are required to investigate the better quality, longer duration, and more clinically meaningful outcomes of lenalidomide in the treatment of MM in Chinese patients.

    Purpose To assess the immunomodulatory and clinical effects of lenalidomide with standard treatment of gemcitabine in patients with advanced pancreatic cancer. Patients and Methods Patients with advanced pancreatic cancer were treated in first line with lenalidomide orally for 21 days of a 28 days cycle and the standard regimen for gemcitabine. In Part I, which we previously have reported, the dose of lenalidomide was defined (n = 12). In Part II, every other consecutive patient was treated with either lenalidomide (Group A, n = 11) or gemcitabine (Group B, n = 10) during cycle 1. From cycle 2 on, all Part II patients received the combination. Results A significant decrease in the proliferative response of peripheral blood mononuclear cells and the frequency of DCs were noted in patients at baseline compared to healthy control donors while the frequencies of CD4+ and CD8+ T cells, NK-cells and MDSCs were significantly higher in patients compared to controls. In Group A, a significant increase in the absolute numbers of activated (HLA-DR+) CD4 and CD8 T cells and CD8 effector memory T cells (pLenalidomide augmented T cell reactivities, which were abrogated by gemcitabine. However, addition of lenalidomide to gemcitabine seemed to have no therapeutic impact compared to gemcitabine alone in this non-randomized study.

    Full Text Available Abstract Background A 24-year-old female patient was diagnosed with classic Hodgkin's lymphoma in clinical stage II, and combination chemotherapy followed by radiotherapy was initiated. During the following 5 years, the disease progressed despite several standard therapeutic approaches, including autologous and allogeneic stem cell transplantation. Methods Lenalidomide (25 mg daily treatment was then initiated in a continuous dosing schedule. Positron emission tomography scans were performed before and during lenalidomide treatment. Hematologic and laboratory values, as well as physical condition were also assessed before and during lenalidomide treatment. Results Four months after continuous lenalidomide treatment, tumor load was significantly reduced, B symptoms had resolved, and the patient's physical condition had improved, allowing her to resume normal daily-living activities. Evaluations after 15 months of lenalidomide treatment indicated limited disease progression. Nevertheless, the patient was feeling well and maintaining a normal active life. Treatment was well tolerated, allowing the patient to remain on continuous dosing, which has now been maintained for 18 months. Conclusion Daily, long-term lenalidomide treatment provided clinical benefit and was well tolerated in a patient with relapsed, advanced classic Hodgkin's lymphoma.

    Myelodysplastic syndromes (MDS) are clonal hematopoietic disorders characterized by bone marrow failure which frequently progress to acute myeloid leukemia. Patients who fail to respond to, or progress on first-line DNA hypomethylating agents (HMA) have a poor prognosis. Conventionally dosed lenalidomide has activity in 5q-MDS. In other subtypes, it may reduce RBC transfusion requirements but does not result in cytogenetic responses. We previously reported that high-dose lenalidomide induction (50 mg/day) results in complete remissions in a high fraction of patients. We, therefore, conducted a Phase 2 trial of the same regimen in MDS refractory to HMA. Marrow complete remissions were seen in 33% of patients and hematological improvement in 8% of patients. Significant infections complicated more than 50% of cases. Future trials to explore alternative dosing schedules of high-dose lenalidomide to increase efficacy while decreasing toxicity are warranted.

IranianJournal of Child Neurology 2012;6(1:5-12.ObjectiveDuchenne muscular dystrophy (DMD is a degenerative disease that usually becomes clinically detectable in childhood as progressive proximal weakness. No cure is yet available for DMD, but the use of steroids improves muscle strength and function. This study has been carried out to select the best steroid for the management of DMD.Materials & MethodsThis study is a single-blind, randomized clinical trial with a sample volume of 34 DMD patients. Half of these patients were treated with deflazacort (0.9 mg/kg daily and the other half with prednisone (0.75 mg/kg daily for a period of 18 months. The motor function score and excess body weight were registered one year after the start and also at the end of the study and compared between the two groups.ResultsDeflazacort was more effective in the improvement of motor function after one year, but there was no significant difference between the two drugs at the end of the study (18 months after start. Weight gain after one year and at the end of the study was higher in prednisone group and steroid treatment with deflazacort appears to cause fewer side effects than prednisone regarding weight gain.ConclusionDeflazacort seems to be more effective than prednisone in the improvement of motor function causing fewer side effects, particularly weight gain. This medication may be important for the improvement of motor function and could be used as the best steroidal treatment for Duchenne muscular dystrophy. References Lankester BJA, Whitehouse MR, Gargan MF.

    Alkylating agents are widely used chemotherapeutics in the treatment of many cancers, including leukemia, lymphoma, multiple myeloma, sarcoma, lung, breast and ovarian cancer. Melphalan is the most commonly used chemotherapeutic agent against multiple myeloma. However, despite a 70-80% initial response rate, virtually all patients eventually relapse due to the emergence of drug-resistant tumour cells. By using global proteomic and transcriptomic profiling on melphalan sensitive and resistant RPMI8226 cell lines followed by functional assays, we discovered changes in cellular processes and pathways not previously associated with melphalan resistance in multiple myeloma cells, including a metabolic switch conforming to the Warburg effect (aerobic glycolysis), and an elevated oxidative stress response mediated by VEGF/IL8-signaling. In addition, up-regulated aldo-keto reductase levels of the AKR1C family involved in prostaglandin synthesis contribute to the resistant phenotype. Finally, selected metabolic and oxidative stress response enzymes were targeted by inhibitors, several of which displayed a selective cytotoxicity against the melphalan-resistant cells and should be further explored to elucidate their potential to overcome melphalan resistance.

    This observational study assessed functional ability in patients treated with modified-release prednisone under conditions of normal clinical practice. Patients treated with modified-release prednisone were observed over 9 months. The primary outcome measure was the change from baseline total score using the Questionnaire on Activity Status (QAS); total QAS score ranges from 0 (severely impaired) to 100 (completely unimpaired). Other measures included Visual Analogue Scale (VAS) from 0 to 10 (where 10 = full daily performance) and Health Assessment Questionnaire Disability Index (HAQ-DI). There were no restrictions on dose of modified-release prednisone or use of concomitant therapy. A total of 1,733 patients were included in the study, with valid observations at baseline and study end for 1,185 patients (thereof 74 % female, median age 59 years, median disease duration 5 years). Mean total QAS score improved significantly after 9 months of treatment with modified-release prednisone from 54.3 to 70.2 (p prednisone was significantly reduced (from 5.0 to 4.4 mg/day, p prednisone. This observational study, conducted under daily-practice conditions, confirms the beneficial effects of modified-release prednisone shown previously in randomised controlled trials.

    Lenalidomide treatment for refractory or relapsed multiple myeloma in elderly patients may be feasible in an outpatient setting. However, difficulties have been associated with the management of adverse effects. Therefore, a dose reduction in lenalidomide has been recommended in some cases. In this report, we encountered the successful treatment of myeloma in 6 elderly patients (aged above 70 years) with very low-dose lenalidomide (5 mg daily). Four patients exhibited more than a partial response with an 8.6 months median follow-up period, which was comparable with previous findings. The major adverse effect observed was infection, which occurred during the first several cycles. Others were less toxic, especially the absence of grade 3/4 toxicities for hematological adverse effects.Although a dose reduction in lenalidomide therapy for elderly patients is controversial, a very low dose could be safe and effective. Our group is currently conducting a multi-center prospective trial to evaluate the efficacy of low-dose lenalidomide therapy.

    This study investigated the activity of lenalidomide in patients with relapsed/refractory chronic lymphocytic leukemia (CLL). Lenalidomide was given at 10 mg daily with dose escalation up to 25 mg daily. Three patients (7%) achieved a complete response (CR), one a nodular partial remission, and 10 patients a partial remission (PR), for an overall response (OR) rate of 32%. Treatment with lenalidomide was associated with an OR rate of 31% in patients with 11q or 17p deletion, of 24% in patients with unmutated V(H), and of 25% in patients with fludarabine-refractory disease. The most common toxicity was myelosuppression, and the median daily dose of lenalidomide tolerated was 10 mg. Plasma levels of angiogenic factors, inflammatory cytokines, and cytokine receptors were measured at baseline, day 7, and day 28. There was a dramatic increase in median interleukin (IL)-6, IL-10, IL-2, and tumor necrosis factor receptor-1 levels on day 7, whereas no changes were observed in median vascular endothelial growth factor levels (20 patients studied). According to our experience, lenalidomide given as a continuous treatment has antitumor activity in heavily pretreated patients with CLL.

    Lenalidomide is an immunomodulatory agent (IMiD) clinically active in chronic lymphocytic leukemia (CLL), both in heavily pre-treated patients and upfront. Lenalidomide has a unique mechanism of action in CLL. Its efficacy relies on a multifactorial mode-of-action (MOA), comprising a plethora of immunomodulatory actions, the disruption of mutualistic interactions inside CLL microenvironment and direct effects against leukemic cells. In the last few years, a number of new and highly effective drugs appeared in the scenario of CLL therapeutic options, i.e. tyrosine kinase inhibitors (TKIs), showing a good safety profile and impressive clinical response, also in high-risk patients. In this review, we describe the data from clinical studies about lenalidomide efficacy in CLL and we critically dissect the different mechanisms of action of this drug. We point the attention on open issues, including drug dosage and administration schedule, prediction of clinical response to lenalidomide, and combination therapeutic strategies. This overview would be useful to envision a possible role of lenalidomide in the treatment flow-chart of CLL, exploiting its peculiar MOA and also exploring the possible synergetic effect with new drugs.

    Full Text Available Purpose: Introduction of lenalidomide has expanded the therapeutic options for refractory and recurrent multiple myeloma (MM patients. However, the application of the approved doses may be difficult in some patients due to adverse effects. Experimental design: Therefore, we evaluated the efficacy and safety of lenalidomide in 10 patients with relapsed and refractory MM who received a reduced dose due to leukopenia (4, polyneuropathy (1, muscle cramps (1, thrombocytopenia (1, renal insufficiency (1, at the request of patient (1, as continuous therapy (1, either from the beginning (2 or during treatment (8.

    Clinical studies have shown that large doses of prednisone could lower serum uric acid (SUA) in patients with decompensated heart failure (HF); however, the optimal dose of prednisone and underlying mechanisms are unknown. Thirty-eight patients with decompensated HF were randomized to receive standard HF care alone (n = 10) or with low-dose (15 mg/day, n = 8), medium-dose (30 mg/day, n = 10), or high-dose prednisone (60 mg/day, n = 10), for 10 days. At the end of the study, only high-dose prednisone significantly reduced SUA, whereas low- and medium-dose prednisone and standard HF care had no effect on SUA. The reduction in SUA in high-dose prednisone groups was associated with a significant increase in renal uric acid clearance. In conclusion, prednisone can reduce SUA levels by increasing renal uric acid clearance in patients with decompensated HF.

    2016-08-01

    Levamisole is an immunomodulatory drug that was previously used to treat various medical conditions, including parasitic infections, nephrotic syndrome, and colorectal cancer. Over the last few years, increasing amounts of levamisole have been used as an adulterant in cocaine. Levamisole-cut cocaine has become a concern because it is known to cause a necrotizing purpuric rash, autoantibody production, and life-threatening leukopenia. Mixed histologic findings of vasculitis and thrombosis are characteristic of levamisole-induced purpura. The recommended management of levamisole-induced vasculitis currently involves withdrawal of the culprit along with supportive treatment. We describe a patient with levamisole-induced vasculitis who continued to develop skin lesions despite self-reported cocaine cessation. Complete resolution of cutaneous disease occurred with the addition of oral prednisone and vardenafil hydrochloride, suggesting the possibility of a new treatment option in patients with refractory disease. In addition, we review the clinical presentation, disease course, diagnostic approach, laboratory findings, histology, and management of levamisole-induced vasculitis. The harmful effects of levamisole-cut cocaine are serious enough that public alerts have been issued to increase awareness. Clinicians should consider the possibility of levamisole exposure in cocaine users presenting with any combination of fever, neutropenia, and necrotic skin lesions, especially in acral areas including the ears.

    Full Text Available Endometrial cancer is one of the most frequently diagnosed cancer in females with prevalence of 22 in 100,000 women. The etiology of the cancer remains unclear. Despite significant progress towards understanding the patho-mechanism of the disease, effective treatment is still lacking. The results of the study suggest that combined treatment of Ishikawa cells for 24 h with disintegrin and then for 24 h with melphalan severely inhibits important biological functions of the cells. We showed that such strategy have a potent cytotoxic effect. The mechanism of process undergoes probably through inhibition of integrin - dependent signaling. In this study we shown down regulation of Shc and FAK proteins in cells treated with echistatin and melphalan. It suggests that signaling pathways that involve Shc and FAK participation may represent target for antineoplastic strategy. The functional significance of the combined treatment of Ishikwa cells with echistatin and melphalan was found at the level of collagen biosynthesis. Decreased biosynthesis of collagen in extracellular matrix may suppress cell growth and induce apoptosis. The treatment with echistatin and melphalan also showed decreased expression of IGF receptor in comparison to the cells treated with both compounds separately. The data presented suggest that combined therapy with disintegrin - echistatin and alkyalting drug - mephalan may represent a new approach to more effective and safe cancer therapy.

    High dose melphalan followed by autologous stem cell transplantation remains standard of care for eligible patients with multiple myeloma, but disease response and toxicity, including severe mucositis, varies among patients. Our randomized trial investigated duration of cryotherapy (2 and 6 hours) for reduction of mucositis prevalence and severity and explored factors associated with variability in pharmacokinetics and outcomes from melphalan therapy. The results demonstrate 2-hour is at least as effective as 6-hour cryotherapy in decreasing severe mucositis. From a population pharmacokinetic model, we identified fat free mass, hematocrit, and creatinine clearance were significant covariates, as had been reported previously. Furthermore, we observed the rs4240803 SLC7A5 polymorphism was significantly associated with pharmacokinetic variability, and pharmacokinetics was associated with both mucositis and neutropenia. However, melphalan exposure was not associated with progression-free or overall survival in our dataset. These findings contribute to ongoing efforts to personalize melphalan dosing in transplant patients. This article is protected by copyright. All rights reserved.

    2015-12-01

    Myelodysplastic syndrome (MDS) is a common hematological disease in patients over sixty. Despite intensive research, the therapy of this heterogeneous blood disease is complicated. In recent years, two new therapeutic approaches have been proposed: immunomodulation and demethylation therapy. Immunomodulation therapy with lenalidomide represents a meaningful advance in the treatment of anemic patients, specifically those with 5q- aberrations. As much as 60-70% of patients respond and achieve transfusion independence. We present the initial lenalidomide experience of the Czech MDS group. We analyze Czech MDS register data of 34 (31 female; 3 male; median age 69 years) chronically transfused low risk MDS patients with 5q- aberration treated by lenalidomide. Twenty-seven (79.4%) patients were diagnosed with 5q- syndrome, 5 patients with refractory anemia with multilineage dysplasia, 1 patient with refractory anemia with excess of blasts 1, and 1 patient with myelodysplastic/myeloproliferative unclassified. Response, as represented by achieving complete transfusion independence, was achieved in 91% of patients. A true 5q- syndrome diagnosis in most our patients may be responsible for such a high response rate. Complete cytogenetic response was reached in 15% of patients and partial cytogenetic response in 67%, within a median time of 12 months. TP53 mutation was detected in 15% (3 from 18 tested) and 2 of these patients progressed to higher grade MDS. The majority of patients tolerated lenalidomide very well. Based on this albeit small study, we present our findings of high lenalidomide efficacy as well as the basic principles and problems of lenalidomide therapy.

    Human growth hormone (hGH) and prednisone cause insulin resistance and glucose intolerance. However, it is unknown whether hGH and prednisone antagonize insulin action on protein, fat, and carbohydrate metabolism by a common or independent mechanism. Therefore, protein, fat, and carbohydrate metabolism was assessed simultaneously in four groups of eight subjects each after 7 days of placebo, recombinant DNA hGH (rhGH; 0.1 mg.kg-1.day-1), prednisone (0.8 mg.kg-1.day-1), or rhGH and prednisone administration after an 18-h fast and during gut infusion of glucose and amino acids (fed state). Fasting plasma glucose concentrations were similar during placebo and rhGH but elevated (P less than 0.001) during combined treatment, whereas plasma insulin concentrations were higher (237 +/- 57 pmol/ml, P less than 0.001) during combined than during placebo, rhGH, or prednisone treatment (34, 52, and 91 pM, respectively). In the fed state, plasma glucose concentrations were elevated only during combined treatment (11.3 +/- 2.1 mM, P less than 0.001). Plasma insulin concentrations were elevated during therapy with prednisone alone and rhGH alone (667 +/- 72 and 564 +/- 65 pmol/ml, respectively, P less than 0.001) compared with placebo (226 +/- 44 pmol/ml) but lower than with the combined rhGH and prednisone treatment (1249 +/- 54 pmol/ml, P less than 0.01). Protein oxidation {sup 14}C leucine increased (P less than 0.001) with prednisone therapy, decreased (P less than 0.001) with rhGH treatment, and was normal during the combined treatment.

    A patient with refractory primary immune thrombocytopenia (ITP) characterised by severe skin and mucosal bleedings was treated with several ITP-directed therapies including cyclophosphamide. He later developed therapy-related del(5q) myelodysplastic syndrome with no dysplastic morphological features in bone marrow. He remained severely thrombocytopenic, which suggests ongoing immune mediated platelet destruction. After two 3 week cycles of low-dose lenalidomide, complete cytogenetic remission and complete normalisation of platelet count were observed. This suggests that lenalidomide may be a viable treatment option for ITP in the presence of del(5q) not responding to standard treatments.

    Lenalidomide is a potent immunomodulatory agent capable of downregulating proinflammatory cytokines such as tumor necrosis factor-α (TNF-α) and upregulating anti-inflammatory cytokines. Lenalidomide has been shown to elicit cardiovascular effects, although its impact on cardiac function remains obscure. This study was designed to examine the effect of lenalidomide on cardiac contractile function in ob/ob obese mice. C57BL lean and ob/ob obese mice were given lenalidomide (50 mg/kg/day, p.o.) for 3 days. Body fat composition was assessed by dual-energy X-ray absorptiometry. Cardiomyocyte contractile and intracellular Ca(2+) properties were evaluated. Expression of TNF-α, interleukin-6 (IL-6), Fas, Fas ligand (FasL), the short-chain fatty acid receptor GPR41, the NFκB regulator IκB, endoplasmic reticulum (ER) stress, the apoptotic protein markers Bax, Bcl-2, caspase-8, tBid, cytosolic cytochrome C, and caspase-12; and the stress signaling molecules p38 and extracellular signal-regulated kinase (ERK) were evaluated by western blot. ob/ob mice displayed elevated serum TNF-α and IL-6 levels, fat composition and glucose intolerance, the effects of which except glucose intolerance and fat composition were attenuated by lenalidomide. Cardiomyocytes from ob/ob mice exhibited depressed peak shortening (PS) and maximal velocity of shortening/relengthening, prolonged time-to-PS and time-to-90% relengthening as well as intracellular Ca(2+) mishandling, which were ablated by lenalidomide. Western blot analysis revealed elevated levels of TNF-α, IL-6, Fas, Bip, Bax, caspase-8, tBid, cleaved caspase-3 caspase-12, cytochrome C, phosphorylation of p38, and ERK in ob/ob mouse hearts, the effects of which with the exception of Bip, Bax, and caspase-12 were alleviated by lenalidomide. Taken together, these data suggest that lenalidomide is protective against obesity-induced cardiomyopathy possibly through antagonism of cytokine/Fas-induced activation of stress signaling and

    The aim of the present study was to evaluate the efficacy of cyclosporine A (CsA) combined with medium/low dose prednisone in the treatment of progressive immunoglobulin A nephropathy (IgAN). Ninety-six patients who satisfied the inclusion criteria were enrolled in a prospective controlled clinical study. They were assigned into two groups and initially given either 0.6-0.8 mg/kg/day prednisone (maximum 40 mg/day) plus 3 mg/kg/day CsA (CsA group), or 1 mg/kg/day prednisone (maximum 60 mg/day) alone (steroid group). During therapy, the dose of prednisone was reduced in both groups and the dose of CsA was gradually tailed off over the first 3 months and maintained at 2 mg/kg/day in the CsA group. Urinary protein excretion, serum biochemical indexes, clinical efficacy and side effects of CsA were assayed. A significant decline in mean 24-hour urinary protein excretion (p prednisone and CsA (p 0.05). CsA at a dose of 2-3 mg/kg/day in combination with medium/low dose prednisone was effective in inducing remission of IgAN, especially for patients with Lee's Grade III IgAN, and is a safe and effective choice for short-term treatment of patients with progressive IgAN.

    In children, the nephrotic syndrome is usually corticoid-responsive; approximately 70% of patients experience relapses, frequently triggered by infections. Our paper presents the results obtained using a 4 month prednisone regimen. This retrospective study included 83 children afflicted with nephrotic syndrome over a 10 year span. We analyzed: age at diagnosis, boys/girls ratio, response to corticoid treatment - after one month of prednisone and at the completion of the treatment course, number of relapses and their frequency, complications of prednisone treatment. The median age at diagnosis was 4.8 years, males predominating M:F = 1.5:1. Complete response after 4 weeks of prednisone therapy was noted in 98.79% of cases. We had 116 episodes of relapses during the first year of follow-up, occurring in 67.4% of children (27.9% were frequent relapsers, 11.62% subsequently became corticoid-dependent). Late relapses, after the first year, occurred in 32.55% of cases. We noted mostly mild adverse effects of the prednisone treatment: occurrence of infections during therapy (16.27%), cushingoid facies (37.2%), hirsutism (4.6%), high blood pressure (4.65%), stretch marks (2.32%). In conclusion, the 4 month prednisone treatment regimen is efficient in inducing and maintaining a remission. The incidence of relapses is 32.55%, comparable to the figure cited in larger studies. Serious adverse effects are significantly lower with this regimen compared to other corticoid treatment schemes. Key wo

    Older patients with acute myeloid leukemia (AML) have limited treatment options and a poor prognosis, thereby warranting novel therapeutic strategies. We evaluated the efficacy of lenalidomide as front-line therapy for older AML patients. In this phase 2 study, patients 60 years of age or older with untreated AML received high-dose (HD) lenalidomide at 50 mg daily for up to 2 28-day cycles. If patients achieved a complete remission (CR)/CR with incomplete blood count recovery (CRi) or did not progress after 2 cycles of HD lenalidomide, they received low-dose lenalidomide (10 mg daily) until disease progression, an unacceptable adverse event, or completion of 12 cycles. Thirty-three AML patients (median age, 71 years) were enrolled with intermediate (55%), unfavorable (39%), or unknown (6%) cytogenetic risk. Overall CR/CRi rate was 30%, and 53% in patients completing HD lenalidomide. The CR/CRi rate was significantly higher in patients presenting with a low (< 1000/μL) circulating blast count (50%, P = .01). The median time to CR/CRi was 30 days, and duration of CR/CRi was 10 months (range, 1- ≥ 17 months). The most common grades ≥ 3 toxicities were thrombocytopenia, anemia, infection, and neutropenia. HD lenalidomide has evidence of clinical activity as initial therapy for older AML patients, and further study of lenalidomide in AML and MDS is warranted. This study is registered at www.clinicaltrials.gov as #NCT00546897.

Modified-release (MR oral prednisone taken at bedtime has been shown to be more effective than immediate-release prednisone taken in the morning. The efficacy of low-dose MR prednisolone in patients with SpA is unknown. Patients and methods: This single-center cohort study retrospectively assessed the effectiveness and safety of 12-week low-dose MR prednisone (5 mg daily, bedtime administration in GC-naïve adult patients with symptomatic axial SpA. A 50% improvement of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI or a final BASDAI score of <4 according to disease activity at baseline was chosen as the primary outcome parameter after MR prednisone. Results: Fifty-seven patients were evaluated; of them, 41 had an active disease (BASDAI score of ≥4 at baseline. MR prednisone significantly reduced BASDAI (from 5.5±2.6 to 3.0±2.8, P<0.001 as well as inflammatory symptoms, pain, fatigue and morning stiffness. The overall response rate after MR prednisone was 52.6% (53.7% in patients with active SpA and 50.0% in patients with low-active disease; nonsignificant. At multivariable analysis, none of the considered clinical findings independently predicted the response to MR prednisone in subjects with active SpA.

    To determine the toxicity and efficacy of isolated hepatic perfusion with tumour necrosis factor alpha (TNF-alpha) and melphalan (Alkeran) under mild hyperthermic conditions. A phase I trial was performed. Eleven patients with unresectable metastatic malignancies in the liver were pre-treated with 3 x 10(6) U leukocyte IFN daily 2 days before the perfusion. The liver was isolated and inflow catheters inserted in the hepatic artery and the portal vein. The hepatic veins were drained via a catheter in the retrohepatic caval vein. The venous blood flow from the lower extremities and the splanchnic circulation was bypassed to the axillar vein. The liver circuit was perfused with oxygenated blood and 30-200 microg TNF-alpha was added. At 39 degrees C in the liver circuit 0.5 mg/kg melphalan was added and the perfusion was continued for 1 h. Six patients underwent re-operation due to post-operative bleeding. Two patients died of coagulopathy or multiple organ failure within the first post-operative month. Three of six patients with liver metastases from malignant melanoma or leiomyosarcoma showed a partial response while no patients with liver metastases from colorectal cancer showed any response. The mean survival time was 20 months, which is within the same range as seen in previous isolated hepatic perfusion (IHP) studies. IHP with this drug regimen is a method with a considerable toxicity, though it is hard to distinguish between toxicity from TNF-alpha and that from the perfusion procedure itself. The method was not effective in patients with colorectal liver metastasis, but the results in melanoma and leiomyosarcoma patients warrant further studies.

  2. Therapeutic Activity of Lenalidomide in Mantle Cell Lymphoma and Indolent Non-Hodgkin’s Lymphomas

    Full Text Available Mantle cell lymphoma (MCL comprises 3–10% of NHL, with survival times ranging from 3 and 5 years. Indolent lymphomas represent approximately 30% of all NHLs with patient survival largely dependent on validated prognostic scores. High response rates are typically achieved in these patients with current first-line chemoimmunotherapy. However, most patients will eventually relapse and become chemorefractory with poor outcome. Alternative chemoimmunotherapy regimens are often used as salvage strategy and stem cell transplant remains an option for selected patients. However, novel approaches are urgently needed for patients no longer responding to conventional chemotherapy. Lenalidomide is an immunomodulatory drug with activity in multiple myeloma, myelodisplastic syndrome and chronic lymphoproliferative disorders. In phase II studies of indolent NHL and MCL lenalidomide has shown activity with encouraging response rates, both as a single agent and in combination with other drugs. Some of these responses may be durable. Optimal dose of lenalidomide has not been defined yet. The role of lenalidomide in the therapeutic armamentarium of patients with indolent NHL or MCL will be discussed in the present paper.

    Lenalidomide is an immunomodulatory drug (IMiDs) with clinical efficacy in multiple myeloma (MM) and other late B-cell neoplasms. Although cereblon (CRBN) is an essential requirement for IMiD action, the complete molecular and biochemical mechanisms responsible for lenalidomide-mediated sensitivity or resistance remain unknown. Here, we report that IMiDs work primarily via inhibition of peroxidase-mediated intracellular H2O2 decomposition in MM cells. MM cells with lower H2O2-decomposition capacity were more vulnerable to lenalidomide-induced H2O2 accumulation and associated cytotoxicity. CRBN-dependent degradation of IKZF1 and IKZF3 was a consequence of H2O2-mediated oxidative stress. Lenalidomide increased intracellular H2O2 levels by inhibiting thioredoxin reductase (TrxR) in cells expressing CRBN, causing accumulation of immunoglobulin light-chain dimers, significantly increasing endoplasmic reticulum stress and inducing cytotoxicity by activation of BH3-only protein Bim in MM. Other direct inhibitors of TrxR and thioredoxin (Trx) caused similar cytotoxicity, but in a CRBN-independent fashion. Our findings could help identify patients most likely to benefit from IMiDs and suggest direct TrxR or Trx inhibitors for MM therapy.

    POEMS syndrome is a multisystem disorder characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. POEMS syndrome is a rare cause of refractory ascites. We report the case of a patient with POEMS syndrome presenting with massive ascites who was treated with very-low-dose lenalidomide and dexamethasone. A 57-year-old Japanese man was admitted to our hospital with pleural effusion, massive ascites, and leg edema. The diagnosis of POEMS syndrome was made based on the combination of the following findings: peripheral neuropathy, organomegaly, endocrinopathy, serum monoclonal protein elevation, skin changes, plasma VEGF elevation, and evidence of extravascular volume overload. Renal dysfunction induced by biopsy-proven renal involvement of POEMS syndrome was observed. Massive ascites of the patient dramatically diminished with long-time treatment of very-low-dose lenalidomide and dexamethasone. Lenalidomide seems to be a very promising therapy for POEMS syndrome presenting with extravascular volume overload such as edema, pleural effusion, and ascites. Very-low-dose lenalidomide might be effective especially for the patients with POEMS-related nephropathy.

    The best initial therapy for elderly patients with chronic lymphocytic leukemia (CLL) has not yet been defined. We investigated the activity of lenalidomide as initial therapy for elderly patients with CLL. Sixty patients with CLL 65 years of age and older received treatment with lenalidomide orally 5 mg daily for 56 days, then titrated up to 25 mg/d as tolerated. Treatment was continued until disease progression. At a median follow-up of 29 months, 53 patients (88%) are alive and 32 patients (53%) remain on therapy. Estimated 2-year progression-free survival is 60%. The overall response rate to lenalidomide therapy is 65%, including 10% complete response, 5% complete response with residual cytopenia, 7% nodular partial response, and 43% partial response. Neutropenia is the most common grade 3 or 4 treatment-related toxicity observed in 34% of treatment cycles. Major infections or neutropenic fever occurred in 13% of patients. Compared with baseline levels, we noted an increase in serum immunoglobulin levels across all classes, and a reduction in CCL3 and CCL4 plasma levels was noted in responding patients. Lenalidomide therapy was well tolerated and induced durable remissions in this population of elderly, symptomatic patients with CLL. This study was registered at www.clinicaltrials.gov as #NCT00535873.

    Lenalidomide is a novel thalidomide analogue with enhanced immunomodulatory and antiangiogenic action lacking most of the typical thalidomide-associated adverse events. In myelodysplastic syndromes (MDS), it has been used primarily in the IPSS low- and intermediate-1 risk setting. Several trials have demonstrated its potential to lead to both erythroid and cytogenetic responses in these disease groups. In a clinical trial of patients with a del(5q) chromosomal abnormality, lenalidomide treatment resulted in red blood cell (RBC) transfusion independence in 67% of patients. Moreover, 45% of patients achieved a complete cytogenetic remission, and 28% achieved a minor cytogenetic remission. This result was independent of karyotype complexity. Lenalidomide might also induce long-term remissions in del(5q) patients with an elevated medullary blast count. In non-del(5q) patients, 43% of patients with confirmed low- and intermediate-1 risk achieved transfusion independence or a reduction of at least 50% of pre-treatment RBC transfusion levels. Adverse events are common but manageable and include neutropenia and thrombocytopenia, pruritus, rash, diarrhea, and others. Lenalidomide will prove an essential part in the armamentarium of MDS therapeutics. Combination therapies with cytokines, demethylating agents, tyrosine kinase inhibitors, or chemotherapy are being investigated and may show additional benefit in both low- and high risk MDS.

    Multiple myeloma (MM) is a hematological malignancy of plasma cells in the bone marrow. Despite multiple treatment options, MM is inevitably associated with drug resistance and poor outcomes. Histone deacetylase inhibitors (HDACi's) are promising novel chemotherapeutics undergoing evaluation in clinical trials for the potential treatment of patients with MM. Although in preclinical studies HDACi's have proven anti-myeloma activity, but in the clinic single-agent HDACi treatments have been limited due to low tolerability. Improved clinical outcomes were reported only when HDACi's were combined with other drugs. Here, we show that a novel pan-HDACi AR-42 downregulates CD44, a glycoprotein that has been associated with lenalidomide and dexamethasone resistance in myeloma both in vitro and in vivo. We also show that this CD44 downregulation is in part mediated by miR-9-5p, targeting insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3), which directly binds to CD44 mRNA and increases its stability. Importantly, we also demonstrate that AR-42 enhances anti-myeloma activity of lenalidomide in primary MM cells isolated from lenalidomide resistant patients and in in vivo MM mouse model. Thus, our findings shed light on potential novel combinatorial therapeutic approaches modulating CD44 expression, which may help overcome lenalidomide resistance in myeloma patients.

    Full Text Available In Canada, lenalidomide combined with dexamethasone (Len/Dex is approved for use in relapsed or refractory multiple myeloma (RRMM. Our expert panel sought to provide an up-to-date practical guide on the use of lenalidomide in the managing RRMM within the Canadian clinical setting, including management of common adverse events (AEs. The panel concluded that safe, effective administration of Len/Dex treatment involves the following steps: (1 lenalidomide dose adjustment based on creatinine clearance and the extent of neutropenia or thrombocytopenia, (2 dexamethasone administered at 20–40 mg/week, and (3 continuation of treatment until disease progression or until toxicity persists despite dose reduction. Based on available evidence, the following precautions should reduce the risk of common Len/Dex AEs: (1 all patients treated with Len/Dex should receive thromboprophylaxis, (2 erythropoiesis-stimulating agents (ESAs should be used cautiously, and (3 females of child-bearing potential and males in contact with such females must use multiple contraception methods. Finally, while Len/Dex can be administered irrespective of prior therapy and in all prognostic subsets, patients with chromosomal deletion 17(p13 have less favorable outcomes with all treatments, including Len/Dex. New directions for the use of lenalidomide in RRMM are also considered.

Here, we investigated the levels of proteins mediating DNA damage signaling and -repair in RPMI8226 multiple myeloma cells and its Melphalan-resistant derivative 8226-LR5. We observed markedly reduced steady-state levels of DNA glycosylases UNG2, NEIL1 and MPG in the resistant cells and cross-resistance to agents inducing their respective DNA base lesions. Conversely, repair of alkali-labile sites was apparently enhanced in the resistant cells, as substantiated by alkaline comet assay, autoribosylation of PARP-1, and increased sensitivity to PARP-1 inhibition by 4-AN or KU58684. Reduced base-excision and enhanced single-strand break repair would both contribute to the observed reduction in genomic alkali-labile sites, which could jeopardize productive processing of the more cytotoxic Melphalan-induced interstrand DNA crosslinks (ICLs. Furthermore, we found a marked upregulation of proteins in the non-homologous end-joining (NHEJ pathway of double-strand break (DSB repair, likely contributing to the observed increase in DSB repair kinetics in the resistant cells. Finally, we observed apparent upregulation of ATR-signaling and downregulation of ATM-signaling in the resistant cells. This was accompanied by markedly increased sensitivity towards Melphalan in the presence of ATR-, DNA-PK, or CHK1/2 inhibitors whereas no sensitizing effect was observed subsequent to ATM inhibition, suggesting that replication blocking lesions are primary triggers of the DNA damage response in the Melphalan resistant cells. In conclusion, Melphalan resistance is apparently contributed by modulation of the DNA damage response at multiple levels, including downregulation of specific repair pathways to avoid repair intermediates that could impair efficient processing of cytotoxic ICLs and ICL-induced DSBs. This study has revealed several novel

    The structural stability and the vibrational spectra of the anticancer drug melphalan and its parent compounds 3-phenylpropionic acid and L-phenylalanine were investigated by the DFT B3LYP/6-311G** calculations. Melphalan and its fundamental compounds were predicted to exist predominantly in non-planar structures. The vibrational frequencies of the low energy structures of melphalan, 3-phenylpropionic acid, and phenylalanine were computed at the DFT B3LYP level of theory. Complete vibrational assignments of the normal modes of melphalan, 3-phenylpropionic acid, and phenylalanine were provided by combined theoretical and experimental data of the molecules. The experimental infrared spectra of phenylalanine and melphalan show a significantly different pattern of the Cdbnd O stretching mode as compared to those of normal carboxylic acids. A comparison of the 3700-2000 cm-1 infrared spectral region of the three molecules suggests the presence of similar intermolecular H-bonding in their condensed phases. The observed infrared and Raman spectra are consistent with the presence of one predominant melphalan conformation at room temperature.

    Refractory congestive heart failure (CHF) with diuretic resistance is life-threatening and predicts a short life expectancy. Glucocorticoids have been proven to have potent diuretic effects in animal studies; however, their efficacy in CHF patients with diuretic resistance is not known. Thirteen CHF patients with significant volume overload and diuretic resistance who failed to respond to a conventional sequential nephron blockade therapeutic strategy; that is, the coadministration of a thiazide (hydrochlorothiazide) and spironolactone, in combination with loop diuretics, were studied. Prednisone (1 mg/kg daily) was then added to standard care, with other medications unchanged, to determine diuretic efficacy in these CHF patients. Variables included body weight, urine volume, serum electrolytes and renal function. Adding prednisone resulted in striking diuresis with a mean (+/- SD) body weight reduction of 9.39+/-3.09 kg. Prednisone significantly decreased serum creatinine by 52.21+/-48.68 mumol/L and increased glomerular filtration rate by 33.63+/-15.87 mL/min/1.73 m(2) compared with baseline. All patients were discharged from hospital with improved clinical status and renal function, and 11 patients remained alive in the long term. The main side effect of prednisone appeared to be hyperglycemia in diabetic patients. The present study demonstrated that prednisone can rapidly eliminate volume overload and improve clinical status and renal function in CHF patients with diuretic resistance. Further prospective randomized clinical studies are warranted to confirm its clinical efficacy.

    Ocular angiogenesis is an important pathologic character of several ocular diseases, such as retinopathy of prematurity, diabetic retinopathy and age-related macular degeneration (AMD). Inhibition of ocular angiogenesis has great therapeutic value for treating these dieses. Here we show that lenalidomide, an anti-tumor drug, has great anti-angiogenic potential in ocular diseases. Lenalidomide inhibits retinal endothelial cell viability in normal and pathological condition, and inhibits VEGF-induced endothelial cell migration and tube formation in vitro. Moreover, lenalidomide inhibits ocular angiogenesis in vivo through the reduction of angiogenesis- and inflammation-related protein expression. Collectively, lenalidomide is a promising drug for treating ocular angiogenesis through its anti-proliferative and anti-inflammatory property.

    Full Text Available Lenalidomide have both immunomodulatory and anti-angiogenic properties which could confer anti-cancer effects. The aim of this study was to assess the feasibility of combining lenalidomide with the standard treatment gemcitabine in pancreatic cancer patients with advanced disease.Eligible patients had locally advanced or metastatic adenocarcinoma of the pancreas. Patients received lenalidomide days 1-21 orally and gemcitabine 1000 mg/m2 intravenously (days 1, 8 and 15, each 28 day cycle. Three cohorts of lenalidomide were examined (Cohort I = 15 mg, Cohort II = 20 mg and Cohort III = 25 mg daily. The maximum tolerated dose (MTD of lenalidomide given in combination with gemcitabine was defined as the highest dose level at which no more than one out of four (25% subjects experiences a dose-limiting toxicity (DLT. Patients should also be able to receive daily low molecular weight heparin (LMWH (e.g. dalteparin 5000 IU s.c. daily as a prophylactic anticoagulant for venous thromboembolic events (VTEs. Twelve patients (n = 4, n = 3 and n = 5 in cohort I, II and III, respectively were enrolled in this study.Median duration of treatment was 11 weeks (range 1-66, and median number of treatment cycles were three (range 1-14. The only DLT was a cardiac failure grade 3 in cohort III. Frequent treatment-related adverse events (AEs (all grades included neutropenia, leucopenia and fatigue (83% each, but there was no febrile neutropenia; thrombocytopenia (75%; dermatological toxicity (75%; diarrhea and nausea (42% each; and neuropathy (42%.This phase I study demonstrates the feasibility of the combination of lenalidomide and gemcitabine as first-line treatment in patients with advanced pancreatic cancer. The tolerability profile demonstrated in the dose escalation schedule of lenalidomide suggests the dosing of lenalidomide to be 25 mg daily on days 1-21 with standard dosing of gemcitabine and merits further evaluation in a phase II trial.ClinicalTrials.gov NCT

    Described herein are clinical and morphologic findings in 2 patients who underwent heart transplantation because of severe heart failure resulting from cardiac sarcoidosis. Although the explanted hearts in each patient had characteristic gross changes of cardiac sarcoidosis, one patient who had been treated with prednisone, had no residual sarcoid granulomas in the myocardium, whereas the other patient, in whom diagnosis was not made until heart transplantation, had innumerable sarcoid granulomas in her heart. This report suggests that prednisone can eliminate sarcoid granulomas in the heart but that their replacement is by dense fibrous tissue, something also likely the result of the granulomas themselves, creating a situation where the treated (prednisone) and the non-treated sarcoid heart may appear similar by gross examination.

    A 78-year-old woman was diagnosed with multiple myeloma (MM: IgG κ type, stage IIIA, ISS III) at a nearby hospital in August 2010. High-dose dexamethasone therapy was ineffective, and she was treated with 2 courses of bortezomib. She was referred to our hospital with back pain and dyspnea in November. She was diagnosed with interstitial pneumonia (IP) and improved rapidly with steroid pulse therapy. Because the involvement of bortezomib was suspected in IP, lenalidomide therapy was selected for MM. Lenalidomide (15 mg) was administered for 2 courses. The patient achieved a PR and the treatment is still ongoing with a good response. According to the interim report on PMS (post-marketing surveillance), 3 of the 1,177 patients treated with lenalidomide developed IP. The dose level was 25 mg in 2 cases and 10 mg in 1 case. The outcomes of these patients were death in 1 case, not recovered in 1 case, and unknown in 1 case. When lenalidomide is used to treat bortezomib-induced IP, there are no rules or regulations about its dose level. In the present case, the dose of lenalidomide (15 mg) was based on the retreatment dose after bone marrow suppression. Low-dose lenalidomide therapy was effective and safe against MM with a bortezomib-associated lung disorder.

    The aim of this study was to investigate whether the specific T cell response against the multiple myeloma Ag HM1.24 is enhanced by the immunomodulatory drug lenalidomide (Revlimid). Ag-specific CD3(+)CD8(+) T cells against the HM1.24 Ag were expanded in vitro by dendritic cells in 29 healthy donors and 26 patients with plasma cell dyscrasias. Ag-specific activation was analyzed by IFN-γ, granzyme B, and perforin secretion using ELISA, ELISPOT assay, and intracellular staining, and generation of Ag-specific T cells was analyzed by tetramer staining. Expression of T cell maturation markers (CD45RA, CD45R0, CCR7, and CD28) was investigated by flow cytometry. We found that activation of HM1.24-specific T cells from healthy donors and patients with plasma cell dyscrasias was enhanced significantly by lenalidomide and furthermore that the impact of lenalidomide on T cells depends on the duration of the exposure. Notably, lenalidomide supports the downregulation of CD45RA on T cells upon activation, observed in healthy donors and in patients in vitro and also in patients during lenalidomide therapy in vivo. We showed for the first time, to our knowledge, that lenalidomide enhances the Ag-specific activation of T cells and the subsequent downregulation of CD45RA expression of T cells in vitro and in vivo.

    Our recent study demonstrated that a novel proteasome inhibitor NPI-0052 is distinct from bortezomib (Velcade) and, importantly, triggers apoptosis in multiple myeloma (MM) cells resistant to bortezomib. Here we demonstrate that combining NPI-0052 and lenalidomide (Revlimid) induces synergistic anti-MM activity in vitro using MM-cell lines or patient MM cells. NPI-0052 plus lenalidomide-induced apoptosis is associated with (1) activation of caspase-8, caspase-9, caspase-12, caspase-3, and poly(ADP) ribose polymerase; (2) activation of BH-3 protein BIM; (3) translocation of BIM to endoplasmic reticulum; (4) inhibition of migration of MM cells and angiogenesis; and (5) suppression of chymotrypsin-like, caspase-like, and trypsin-like proteasome activities. Importantly, blockade of BIM using siRNA significantly abrogates NPI-0052 plus lenalidomide-induced apoptosis. Furthermore, studies using biochemical inhibitors of caspase-8 versus caspase-9 demonstrate that NPI-0052 plus lenalidomide-triggered apoptosis is primarily dependent on caspase-8 signaling. In animal tumor model studies, low-dose combination of NPI-0052 and lenalidomide is well tolerated, significantly inhibits tumor growth, and prolongs survival. Taken together, our study provides the preclinical rationale for clinical protocols evaluating lenalidomide together with NPI-0052 to improve patient outcome in MM.

    Lenalidomide is an oral immunomodulatory drug with significant activity in indolent B-cell and mantle cell lymphomas. Lenalidomide has a manageable safety profile whether administered as a single agent or in combination with rituximab. The combination of lenalidomide with rituximab, known as the 'R(2)' regimen, enhances efficacy over what has been shown with monotherapy and has demonstrated activity in patients considered resistant to rituximab. Tolerability of these regimens has been consistent among studies. Asymptomatic neutropenia is the most common grade 3/4 adverse event, typically managed by dose interruption, followed by dose reduction once neutrophils have recovered. Nonhematologic toxicities (e.g. fatigue) are generally low-grade, manageable with concomitant treatment, and/or lenalidomide dose modification. More frequent with R(2), immune-related symptoms such as rash and tumor flare are important to recognize as lenalidomide-associated treatment effects in patients with lymphoma who require supportive care and potential dose modifications. Severe tumor flare reactions with painful lymphadenopathy are not typically observed outside of chronic lymphocytic leukemia/small lymphocytic lymphoma. Venous thromboembolism is uncommon in lymphomas, though prophylaxis is recommended. The general safety profile, differences between lenalidomide monotherapy and R(2) treatment, and optimal strategies for managing adverse events are discussed here.

    Prednisone is often used for the treatment of autoimmune and inflammatory diseases but they suffer from variable therapeutic responses and significant adverse effects. Serum biological markers that are modulated by chronic corticosteroid use have not been identified. Myasthenia gravis is an autoimmune neuromuscular disorder caused by antibodies directed against proteins present at the post-synaptic surface of neuromuscular junction resulting in weakness. The patients with myasthenia gravis are primarily treated with prednisone. We analyzed the metabolomic profile of serum collected from patients prior to and after 12 weeks of prednisone treatment during a clinical trial. Our aim was to identify metabolites that may be treatment responsive and be evaluated in future studies as potential biomarkers of efficacy or adverse effects. Ultra-performance liquid chromatography coupled with electro-spray quadrupole time of flight mass spectrometry was used to obtain comparative metabolomic and lipidomic profile. Untargeted metabolic profiling of serum showed a clear distinction between pre- and post-treatment groups. Chronic prednisone treatment caused upregulation of membrane associated glycerophospholipids: phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, 1, 2-diacyl-sn glycerol 3 phosphate and 1-Acyl-sn-glycero-3-phosphocholine. Arachidonic acid (AA) and AA derived pro-inflammatory eicosanoids such as 18-carboxy dinor leukotriene B4 and 15 hydroxyeicosatetraenoic acids were reduced. Perturbations in amino acid, carbohydrate, vitamin and lipid metabolism were observed. Chronic prednisone treatment caused increase in membrane associated glycerophospholipids, which may be associated with certain adverse effects. Decrease of AA and AA derived pro-inflammatory eicosanoids demonstrate that immunosuppression by corticosteroid is via suppression of pro-inflammatory pathways. The study identified metabolomic fingerprints that can now be validated as prednisone

    Full Text Available Background: Lenalidomide has emerged as an important treatment for patients with multiple myeloma (MM. However, its role in the management of MM is still controversial and requires further clarification. The aim of this study was to evaluate efficacy and safety of lenalidomide for MM using a meta-analysis. Methods: We searched the electronic databases including: PubMed, EMBASE and the Cochrane Center Register of Controlled Trials. Seven randomized clinical trials were identified, which included a total of 2357 patients with MM who received lenalidomide-containing, noncontaining lenalidomide regimens or placebo as induction therapy or maintenance therapy. The outcomes included overall response (OR rate, complete response (CR rate, 3-year progression-free survival (PFS rate, 3-year overall survival (OS rate, and different types of treatment-related adverse events. We calculated the risk ratios (RRs as well as their 95% confidence intervals of these outcomes and pooled the results using RevMan 5.2 software. Results: For patients with previously untreated MM, OR rate and CR rate was significantly higher in lenalidomide-containing group than the control group. For relapsed or refractory MM patients, lenalidomide-containing regimens significantly improved the OR rate, CR rate, 3-year PFS rate and 3-year OS rate. With regard to MM patients after autologous stem cell transplantation, lenalidomide maintenance therapy significantly improved 3-year PFS rate but did not result in improved 3-year OS rate. In terms of toxicities, lenalidomide therapy has a higher rate of Grade 3-4 grade cytopenias, infection, deep-vein thrombosis, and diarrhea. Furthermore, the incidence of second primary malignancies was significantly higher in the lenalidomide group. Conclusions: The lenalidomide-containing regimens as induction therapy clearly increased response rates and improved intervals of survival with acceptable toxicity rates for patients with MM. However, when

    Plasmablastic lymphoma (PBL) is an uncommon variant of diffuse large B-cell lymphoma that is characterized by its plasmacytoid features, aggressive tendencies, and frequent association with human immunodeficiency virus (HIV) infection or other immunocompromised states. Multi-agent, intensive chemotherapy regimens are recommended as first-line treatment by the National Comprehensive Cancer Network. However, the toxicity of these regimens is high and prognosis remains poor. We report a patient with HIV-negative PBL who achieved complete response and durable remission using a lenalidomide-based chemotherapy regimen as first-line therapy. Cyclophosphamide, lenalidomide, dexamethasone (CRD) may provide an alternative initial therapeutic option for patients with PBL who cannot tolerate the intensive chemotherapy regimens currently recommended. © 2017 S.

    Celgene has developed and operated pregnancy prevention programs since 1998 with the first approval of thalidomide in the US. With the development and marketing of lenalidomide, an analog of thalidomide, the company further advanced its risk management activities, which now cover several territories across the globe. To date, the program is a success in as much as it has minimized the risk of fetal exposure and subsequent development of fetal malformations. Nonetheless, the company understands the need to provide a mechanism for intervention and remediation when at-risk behaviors are identified, and this forms an integral part of the risk management processes. The implementation of the thalidomide and lenalidomide pregnancy prevention program partners patients, healthcare professionals, regulators and the company in a spirit of shared responsibility. This paper also presents the authors' experience and perspective on the challenges of managing a pregnancy prevention program, which at its core aims at ensuring that the product's benefits outweigh the risk of fetal exposure.

    Triple immunosuppressive therapy after organ transplantation may cause several gastrointestinal disturbances. It is difficult to identify which drug causes more complications, requiring an appropriate animal model. The aim was to compare the gastrointestinal transit in immunosuppressed rats under triple immunosuppressive therapy. Male rats were immunosuppressed by gavage during 14 days with tacrolimus (n = 10), cyclosporine (n = 12), and prednisone (n = 9). Animals received a magnetic pellet before (control) and after treatment that was monitored at predetermined intervals by AC biosusceptometry, a noninvasive and radiation-free technique. The following parameters were measured: creatinine serum, mean time of gastric emptying (MGET), mean time to reach cecum (MCAT), and mean transit time through small bowel (MSBTT). The differences were analyzed by ANOVA (Tukey). Our results showed that MGET of animals treated with prednisone, cyclosporine, and tacrolimus were reduced compared with control subjects (P prednisone compared with control subjects (P prednisone and tacrolimus presented a reduced MGET (P < .05 and P < .01, respectively) compared with cyclosporine. Our data showed a low serum creatinine level and no difference among groups regarding renal function. In summary, cyclosporine has less effect on the gastrointestinal transit; however, all of these drugs should be carefully prescribed to prevent gastrointestinal symptoms and improve quality of life after transplantation.

    In rheumatoid arthritis (RA), nocturnal release of proinflammatory cytokines is not adequately counteracted by endogenous glucocorticoid and is associated with symptoms of morning stiffness and pain. Taking exogenous glucocorticoid during the night reduces morning stiffness significantly more than treatment at the conventional time in the morning, although waking to take tablets is unacceptable for patients. Modified-release prednisone tablets were developed to allow administration at bedtime for programmed delivery of glucocorticoid during the night. Single-center crossover studies were conducted, each in ≤24 healthy subjects, to compare the pharmacokinetics of a single 5-mg oral dose of modified-release prednisone and conventional prednisone, as well as the effect of food on bioavailability. There was no substantial difference in pharmacokinetic parameters of the formulations apart from the programmed delay in release of glucocorticoid from the modified-release tablets (C(max) 97%, AUC(0-∞) 101%, 90% confidence intervals within the requisite range for bioequivalence). Administration after a full or light meal did not affect pharmacokinetic characteristics, but bioavailability was reduced under fasted conditions. Pharmacokinetic evaluation in 9 patients with RA confirmed that modified-release prednisone tablets taken at bedtime (around 22:00 h) with or after an evening meal result in programmed release of glucocorticoid 4 to 6 hours after intake.

    Full Text Available Abstract Introduction Circumscript, progressing lipoatrophy at the insulin injection sites is an unexplained, however rare condition in diabetes mellitus. Case presentation We report a case of severe localised lipoatrophy developing during insulin pump-treatment (continuous subcutaneous insulin infusion with the insulin analogue lispro (Humalog® in a woman with type-1 diabetes mellitus. After 11 months of progressing lipoatrophy at two spots on the abdomen, low-dose prednisone (5-10 mg p.o. was given at breakfast for 8 months, whereby the atrophic lesions centripetally re-filled with subcutaneous fat tissue (confirmed by MRI despite ongoing use of insulin lispro. However, 4 weeks after cessation of prednisone, lipoatrophy relapsed, but resolved after another 2 months of low-dose prednisone. No further relapse was noted during 12 months of follow-up on insulin-pump therapy with Humalog®. Conclusion Consistent with an assumed inflammatory nature of the condition, low-dose oral prednisone appeared to have cured the lipoatrophic reaction in our patient. Our observation suggests a temporary intolerance of the subcutaneous fat tissue to insulin lispro (Humalog®, triggered by an unknown endogenous mechanism.

  20. Evidence for different mechanisms of ‘unhooking’ for melphalan and cisplatin-induced DNA interstrand cross-links in vitro and in clinical acquired resistant tumour samples

    Full Text Available Abstract Background DNA interstrand cross-links (ICLs are critical lesions produced by several cancer chemotherapy agents including platinum drugs and nitrogen mustards. We have previously shown in haematological (multiple myeloma and solid tumours (ovarian cancer that clinical sensitivity to such agents can result from a defect in DNA ICL processing leading to their persistence. Conversely, enhanced repair can result in clinical acquired resistance following chemotherapy. The repair of ICLs is complex but it is assumed that the ‘unhooking’ step is common to all ICLs. Methods Using a modification of the single cell gel electrophoresis (Comet assay we measured the formation and unhooking of melphalan and cisplatin-induced ICLs in cell lines and clinical samples. DNA damage response in the form of γ-H2AX foci formation and the formation of RAD51 foci as a marker of homologous recombination were also determined. Real-time PCR of 84 genes involved in DNA damage signalling pathways was also examined pre- and post-treatment. Results Plasma cells from multiple myeloma patients known to be clinically resistant to melphalan showed significant unhooking of melphalan-induced ICLs at 48 hours, but did not unhook cisplatin-induced ICLs. In ovarian cancer cells obtained from patients following platinum-based chemotherapy, unhooking of cisplatin-induced ICLs was observed at 48 hours, but no unhooking of melphalan-induced ICLs. In vitro, A549 cells were proficient at unhooking both melphalan and cisplatin-induced ICLs. γ-H2AX foci formation closely followed the formation of ICLs for both drugs, and rapidly declined following the peak of formation. RPMI8226 cells unhooked melphalan, but not cisplatin-induced ICLs. In these cells, although cross-links form with cisplatin, the γ-H2AX response is weak. In A549 cells, addition of 3nM gemcitabine resulted in complete inhibition of cisplatin-induced ICL unhooking but no effect on repair of melphalan ICLs. The

    Intra-arterial chemotherapy is a novel therapeutic modality for retinoblastoma patients. Intra-arterial chemotherapy involves the administration of a super-selective drug through the ophthalmic artery, resulting in better ocular penetration and low systemic toxicity. The aim of this report was to evaluate the feasibility of intra-arterial chemotherapy in a large referral center in Mexico City. We included patients with bilateral retinoblastoma, one enucleation, and active disease in the other eye after at least two courses of systemic chemotherapy combined with topical treatments. All patients were treated with three courses of a combination of melphalan 4 mg and topotecan 1 mg. Patients were examined under general anesthesia three weeks after each chemotherapy cycle. From 14 eligible patients, three could not be treated due to inaccessibility of the ophthalmic artery. A complete response was observed in 5/11 patients, three in Stage C according to the International Classification for Intraocular Retinoblastoma, one in Stage D, and one in Stage B. The eyes of three patients were enucleated as a result of active/progressive disease, one in Stage B and two in Stage D. Eye preservation was 55% after a mean follow-up of 171 days (range 21-336). Super-selective intra-arterial chemotherapy is safe and effective for preventing the enucleation of 55% of affected eyes in this group of patients.

    A panel of in vitro tests intended for evaluation of the nano-sized drug delivery systems' compliance with human blood was applied to liposomal formulations of anticancer lipophilic prodrugs incorporated into the lipid bilayer. Liposomes on the basis of natural phosphatidylcholine (PC) and phosphatidylinositol (PI), 8:1 (mol) were loaded with 10 mol% of either methotrexate or melphalan 1,2-dioleoylglyceride esters (MTX-DOG and Mlph-DOG respectively) and either decorated with 2 mol% of sialyl Lewis X/A (SiaLe(X/A)) tetrasaccharide ligand or not. Hemolysis rate, red blood cells and platelets integrity and size distribution, complement (C) activation, and coagulation cascade functioning were analyzed upon the material incubation with whole blood. Both formulations were negatively charged with the zeta potential value being higher in the case of MTX-DOG liposomes, which also were larger than Mlph-DOG liposomes and more prone to aggregation. Accordingly, in hemocompatibility tests Mlph-DOG liposomes did not provoke any undesirable effects, while MTX-DOG liposomes induced significant C activation and abnormal coagulation times in a concentration-dependent manner. Reactivity of the liposome surface was not affected by the presence of SiaLe(X/A) or PI. Decrease in liposome loading with MTX-DOG from 10 to 2.5% resulted in lower surface charge density, smaller liposome size and considerably reduced impact on C activation and coagulation cascades.

    Lenalidomide (Revlimid; Selleck Chemicals, Houston, TX, USA), an analogue of thalidomide, possesses potent cytokine modulatory capacity through inhibition of cytokines such as tumour necrosis factor (TNF)-α, a cytokine pivotal for the onset and development of complications in obesity and diabetes mellitus. The present study was designed to evaluate the effect of lenalidomide on oxidative stress, protein and DNA damage in multiple organs in an ob/ob murine model of obesity. To this end, C57BL/6 lean and ob/ob obese mice were administered lenalidomide (50 mg/kg per day, p.o.) for 5 days. Oxidative stress, protein and DNA damage were assessed using the conversion of reduced glutathione (GSH) to oxidized glutathione (GSSG), carbonyl formation and Comet assay, respectively. Apoptosis was evaluated using caspase 3 activity, and levels of Bax, Bcl-2, Bip, caspase 8, caspase 9 and TNF-α were assessed using western blot analysis. Lenalidomide treatment did not affect glucose clearance in lean or ob/ob mice. Obese mice exhibited a reduced GSH/GSSG ratio in the liver, gastrocnemius skeletal muscle and small intestine, as well as enhanced protein carbonyl formation, DNA damage and caspase 3 activity in the liver, kidney, skeletal muscle and intestine; these effects were alleviated by lenalidomide, with the exception of obesity-associated DNA damage in the liver and kidney. Western blot analysis revealed elevated TNF-α, Bax, Bcl-2, Bip, caspase 8 and caspase 9 in ob/ob mice with various degrees of reversal by lenalidomide treatment. Together, these data indicate that lenalidomide protects against obesity-induced tissue injury and protein damage, possibly in association with antagonism of cytokine production and cytokine-induced apoptosis and oxidative stress.

    The few studies that have examined rates of acute myeloid leukemia (AML) transformation in lenalidomide-treated myelodysplastic syndrome (MDS) patients have been limited to deletion 5q MDS. The association between lenalidomide and subsequent primary malignancies (SPMs) in MDS patients has not been evaluated previously. We conducted a retrospective cohort study to evaluate the risk of both SPM and AML in association with lenalidomide. A cohort of MDS patients (n = 1248) treated between 2004 and 2012 at Moffitt Cancer Center were identified, and incident cases of SPM and AML transformation were ascertained. Using a nested case-control design, MDS controls were 1:1 matched to SPM (n = 41) and AML (n = 150) cases, on age and date of MDS diagnosis, gender, follow-up time, IPSS, and del (5q). Associations between lenalidomide and (1) SPM incidence and (2) AML transformation were estimated with hazards ratios (HR) and 95% confidence intervals (CIs) in the cohort and odds ratios (OR) in the case-control analysis. SPM incidence did not differ significantly between cohort MDS patients treated with (0.7 per 100 person-years) or without lenalidomide (1.4 per 100 person-years) (HR = 1.04, 95% CI = 0.40-2.74), whereas a significantly reduced SPM risk was observed in the case-control sample (OR = 0.03, 95% CI = Lenalidomide was not associated with AML transformation in the cohort analysis (HR = 0.75, 95% CI = 0.44-1.27) or in the case-control analyses (OR = 1.16, 95% CI = 0.52-2.56), after adjustment for potential confounders. Lenalidomide was not associated with increased risk of SPM or AML transformation in a large cohort of MDS patients mostly including nondeletion 5q MDS.

    Anemia remains the principal management challenge for patients with lower risk Myelodysplastic Syndromes (MDS). Despite appropriate cytokine production and cellular receptor display, erythropoietin receptor (EpoR) signaling is impaired. We reported that EpoR signaling is dependent upon receptor localization within lipid raft microdomains, and that disruption of raft integrity abolishes signaling capacity. Here, we show that MDS erythroid progenitors display markedly diminished raft assembly and smaller raft aggregates compared to normal controls (p = 0.005, raft number; p = 0.023, raft size). Because lenalidomide triggers raft coalescence in T-lymphocytes promoting immune synapse formation, we assessed effects of lenalidomide on raft assembly in MDS erythroid precursors and UT7 cells. Lenalidomide treatment rapidly induced lipid raft formation accompanied by EpoR recruitment into raft fractions together with STAT5, JAK2, and Lyn kinase. The JAK2 phosphatase, CD45, a key negative regulator of EpoR signaling, was displaced from raft fractions. Lenalidomide treatment prior to Epo stimulation enhanced both JAK2 and STAT5 phosphorylation in UT7 and primary MDS erythroid progenitors, accompanied by increased STAT5 DNA binding in UT7 cells, and increased erythroid colony forming capacity in both UT7 and primary cells. Raft induction was associated with F-actin polymerization, which was blocked by Rho kinase inhibition. These data indicate that deficient raft integrity impairs EpoR signaling, and provides a novel strategy to enhance EpoR signal fidelity in non-del(5q) MDS.

    The precise molecular mechanism of action and targets through which thalidomide and related immunomodulatory drugs (IMiDs) exert their antitumor effects remains unclear. We investigated the role of cereblon (CRBN), a primary teratogenic target of thalidomide, in the antimyeloma activity of IMiDs. CRBN depletion is initially cytotoxic to human myeloma cells, but surviving cells with stable CRBN depletion become highly resistant to both lenalidomide and pomalidomide, but not to the unrelated dr...

    Full Text Available Autism affects 1 : 88 children in the United States. Familial history of autoimmune disease, autoantibodies in the serum of mothers when there is more than one autistic offspring, and neuroglial response in CSF and brain tissue in autistic patients suggest an immunological variable may be associated with this condition. Lenalidomide has the potential to invoke changes in TNF-α with less toxicity than thalidomide. This pilot study evaluated lenalidomide at reduction of TNF-α and improvement of behavior and language in children with autism with elevated TNF-α. Subjects with elevated TNF-α were given 2.5 mgs lenalidomide daily for 12-weeks. Pharmacodynamics and safety was evaluated. Changes in language and autistic behaviors after six and twelve weeks were measured. Although statistical significance was not achieved for most measures, there were trends toward improvement. After 6-weeks, mean receptive language increased: 60.67 ± 12.06 to 65.00 ± 15.10 (P = 0.11 and symptoms of autism decreased (40.75 ± 5.96 versus 38.67 ± 7.90, P = 0.068. After 12-weeks, CSF-TNF-α declined 57% ± 25% from 80.5 ± 41.03 to 38.0 ± 31.27 (P = 0.068. Serum TNF-α declined 57% (92.50 ± 68.92 to 40.25 ± 44.53 (P = 0.048. This study suggests that lenalidomide is tolerated as a treatment by children with autism and should be further studied as a potential agent for cytockine inflammation.

    Melphalan followed by hematopoietic stem-cell transplantation (HSCT) is the standard treatment for multiple myeloma and other hematopoietic neoplasms. However, high doses of melphalan cause severe oral mucositis (OM). The objective was to verify the efficacy of cryotherapy plus laser therapy on reduction of OM severity. HSCT patients undergoing melphalan chemotherapy (n = 71) were randomly divided into two groups according to OM treatment: oral cryotherapy performed with ice chips for 1 h 35 min followed by low-level laser therapy (InGaAIP, 660 nm, 40 mW, 6 J/cm(2) ) (n = 54) and laser therapy alone with the same protocol (n = 17). A control group (n = 33) was composed of HSCT patients treated with melphalan who received no specific treatment for OM. OM scores and clinical information were collected from D0 to D + 11. The cryotherapy/laser therapy group showed the lowest OM scores (maximum Grade I) and the lowest mean number of days (8 days) with OM in comparison with the other groups (p cryotherapy with laser therapy was effective in reducing OM severity in HSCT patients who underwent melphalan conditioning.

  13. Proof of the concept to use a malignant B cell line drug screen strategy for identification and weight of melphalan resistance genes in multiple myeloma.

    Full Text Available In a conceptual study of drug resistance we have used a preclinical model of malignant B-cell lines by combining drug induced growth inhibition and gene expression profiling. In the current report a melphalan resistance profile of 19 genes were weighted by microarray data from the MRC Myeloma IX trial and time to progression following high dose melphalan, to generate an individual melphalan resistance index. The resistance index was subsequently validated in the HOVON65/GMMG-HD4 trial data set to prove the concept. Biologically, the assigned resistance indices were differentially distributed among translocations and cyclin D expression classes. Clinically, the 25% most melphalan resistant, the intermediate 50% and the 25% most sensitive patients had a median progression free survival of 18, 32 and 28 months, respectively (log-rank P-value  = 0.05. Furthermore, the median overall survival was 45 months for the resistant group and not reached for the intermediate and sensitive groups (log-rank P-value  = 0.003 following 38 months median observation. In a multivariate analysis, correcting for age, sex and ISS-staging, we found a high resistance index to be an independent variable associated with inferior progression free survival and overall survival. This study provides clinical proof of concept to use in vitro drug screen for identification of melphalan resistance gene signatures for future functional analysis.

    Patients with chronic lymphocytic lymphoma (CLL) with high-risk cytogenetics [del(11q)(q22.3) or del(17p)(p13.1)] have limited therapeutic options and their prognosis remains poor. This analysis was conducted to determine the clinical activity of lenalidomide in patients with high-risk disease. Relapsed/refractory patients with CLL enrolled in a phase II clinical trial who had del(11q)(q22.3) or del(17p)(p13.1) were included in this analysis. Patients received single agent lenalidomide for 21 days of the 4 week treatment cycle. The overall response rate among patients with high-risk cytogenetics was 38%, with 19% of patients achieving a complete response. Median progression-free survival was 12.1 months, which is higher than demonstrated with other agents in comparable patient populations. In addition, the estimated 2-year survival probability was 58%, demonstrating that the responses achieved with lenalidomide are durable, even in patients with CLL with high-risk disease with poor risk cytogenetics.

    Abiraterone acetate, a prodrug of the CYP17A1 inhibitor abiraterone that blocks androgen biosynthesis, is approved for treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) in combination with prednisone or prednisolone 5 mg twice daily. This review evaluates the basis for the effects of prednisone on mineralocorticoid-related adverse events that arise because of CYP17A1 inhibition with abiraterone. Coadministration with the recommended dose of glucocorticoid compensates for abiraterone-induced reductions in serum cortisol and blocks the compensatory increase in adrenocorticotropic hormone seen with abiraterone. Consequently, 5 mg prednisone twice daily serves as a glucocorticoid replacement therapy when coadministered with abiraterone acetate, analogous to use of glucocorticoid replacement therapy for certain endocrine disorders. We searched PubMed to identify safety concerns regarding glucocorticoid use, placing a focus on longitudinal studies in autoimmune and inflammatory diseases and cancer. In general, glucocorticoid-related adverse events, including bone loss, immunosuppression, hyperglycemia, mood and cognitive alterations, and myopathy, appear dose related and tend to occur at doses and/or treatment durations greater than the low dose of glucocorticoid approved in combination with abiraterone acetate for the treatment of mCRPC. Although glucocorticoids are often used to manage tumor-related symptoms or to prevent treatment-related toxicity, available evidence suggests that prednisone and dexamethasone might also offer modest therapeutic benefit in mCRPC. Given recent improvements in survival achieved for mCRPC with novel agents in combination with prednisone, the risks of these recommended glucocorticoid doses must be balanced with the benefits shown for these regimens.

    Full Text Available This study assessed the immunomodulatory effects in previously treated KRAS-mutant metastatic colorectal cancer patients participating in a phase II multicenter, open-label clinical trial receiving lenalidomide alone or lenalidomide plus cetuximab. The main findings show the T cell immunostimulatory properties of lenalidomide as the drug induced a decrease in the percentage CD45RA(+ naïve T cells 3-fold while increasing the percentage HLA-DR(+ activated T helper cells and percentage total CD45RO(+ CD8(+ memory T cytotoxic cells, 2.6- and 2.1-fold respectively (p<0.0001. In addition, lenalidomide decreased the percentage of circulating CD19(+ B cells 2.6-fold (p<0.0001. Lenalidomide increased a modest, yet significant, 1.4-fold change in the percentage of circulating natural killer cells. Our findings indicate that lenalidomide significantly activates T cells, suggestive of an immunotherapeutic role for this drug in settings of maintenance therapy and tumor immunity. Furthermore, reported for the first time is the effect of lenalidomide in combination with cetuximab on T cell function, including increases in circulating naïve and central memory T cells. In summary, lenalidomide and cetuximab have significant effects on circulating immune cells in patients with colorectal carcinoma.ClinicalTrials.gov NCT01032291.

    Lenalidomide has demonstrated clinical activity in patients with chronic lymphocytic leukemia (CLL), even though it is not cytotoxic for primary CLL cells in vitro. We examined the direct effect of lenalidomide on CLL-cell proliferation induced by CD154-expressing accessory cells in media containing interleukin-4 and -10. Treatment with lenalidomide significantly inhibited CLL-cell proliferation, an effect that was associated with the p53-independent upregulation of the cyclin-dependent kinase inhibitor, p21(WAF1/Cip1) (p21). Silencing p21 with small interfering RNA impaired the capacity of lenalidomide to inhibit CLL-cell proliferation. Silencing cereblon, a known molecular target of lenalidomide, impaired the capacity of lenalidomide to induce expression of p21, inhibit CD154-induced CLL-cell proliferation, or enhance the degradation of Ikaros family zinc finger proteins 1 and 3. We isolated CLL cells from the blood of patients before and after short-term treatment with low-dose lenalidomide (5 mg per day) and found the leukemia cells were also induced to express p21 in vivo. These results indicate that lenalidomide can directly inhibit proliferation of CLL cells in a cereblon/p21-dependent but p53-independent manner, at concentrations achievable in vivo, potentially contributing to the capacity of this drug to inhibit disease-progression in patients with CLL.

    Lenalidomide has demonstrated clinical activity in patients with chronic lymphocytic leukemia (CLL), even though it is not cytotoxic for primary CLL cells in vitro. We examined the direct effect of lenalidomide on CLL-cell proliferation induced by CD154-expressing accessory cells in media containing interleukin-4 and -10. Treatment with lenalidomide significantly inhibited CLL-cell proliferation, an effect that was associated with the p53-independent upregulation of the cyclin-dependent kinase inhibitor, p21WAF1/Cip1 (p21). Silencing p21 with small interfering RNA impaired the capacity of lenalidomide to inhibit CLL-cell proliferation. Silencing cereblon, a known molecular target of lenalidomide, impaired the capacity of lenalidomide to induce expression of p21, inhibit CD154-induced CLL-cell proliferation, or enhance the degradation of Ikaros family zinc finger proteins 1 and 3. We isolated CLL cells from the blood of patients before and after short-term treatment with low-dose lenalidomide (5 mg per day) and found the leukemia cells were also induced to express p21 in vivo. These results indicate that lenalidomide can directly inhibit proliferation of CLL cells in a cereblon/p21-dependent but p53-independent manner, at concentrations achievable in vivo, potentially contributing to the capacity of this drug to inhibit disease-progression in patients with CLL.

    The impact of lenalidomide treatment on long-term outcomes of patients with lower risk myelodysplastic syndromes (MDS) and chromosome 5q deletion (del(5q)) is unclear. This study used time-dependent multivariate methodology to analyse the influence of lenalidomide therapy on overall survival (OS) and acute myeloblastic leukaemia (AML) progression in 215 patients with International Prognostic Scoring System (IPSS) low or intermediate-1 risk and del(5q). There were significant differences in several relevant characteristics at presentation between patients receiving (n = 86) or not receiving lenalidomide (n = 129). The 5-year time-dependent probabilities of OS and progression to AML were 62% and 31% for patients receiving lenalidomide and 42% and 25% for patients not receiving lenalidomide; differences were not statistically significant in multivariate analysis that included all variables independently associated with those outcomes (OS, P = 0·45; risk of AML, P = 0·31, respectively). Achievement of RBC transfusion independency (P = 0·069) or cytogenetic response (P = 0·021) after lenalidomide was associated with longer OS in multivariate analysis. These data clearly show that response to lenalidomide results in a substantial clinical benefit in lower risk MDS patients with del(5q). Lenalidomide treatment does not appear to increase AML risk in this population of patients.

    Full Text Available Background: The introduction of the immunomodulatory drug lenalidomide has revolutionized the treatment of patients with myelodysplastic syndromes (MDS and deletion of the long arm of chromosome 5. Treatment with lenalidomide results in transfusion independence in the majority of patients, but some questions remain unresolved, among them the duration of treatment. Moreover, a number of unexpected long-term remissions in patients who stopped lenalidomide for various reasons have been observed. Case Report: We report the case of a 60-year-old Caucasian male with deletion of the long arm of chromosome 5 and International Prognostic Scoring System (IPSS-defined low-risk MDS who was treated with lenalidomide, achieving complete cytogenetic remission and erythroid response. After tapering off and interrupting the treatment, the patient relapsed and showed a new response by lenalidomide retreatment. Six years after the initial treatment, we registered a durable erythroid long-term response and good tolerance, but there was no evidence of a very profound cytogenetic response compared to using lenalidomide as a first-line treatment. Cytogenetic and fluorescence in situ hybridization together with hemoglobin level, mean corpuscular volume (MCV and vitamin B12 level helped us to monitor the patient response; during the various phases of lenalidomide treatment, MCV and vitamin B12 normalization correlated with good response. Conclusion: Lenalidomide interruption and rechallenge in some 5q- MDS patients, with low risk according to the IPSS, is safe and feasible but does not result in a profound cytogenetic response.

    Purpose Lenalidomide maintenance therapy after autologous stem-cell transplantation (ASCT) demonstrated prolonged progression-free survival (PFS) versus placebo or observation in several randomized controlled trials (RCTs) of patients with newly diagnosed multiple myeloma (NDMM). All studies had PFS as the primary end point, and none were powered for overall survival (OS) as a primary end point. Thus, a meta-analysis was conducted to better understand the impact of lenalidomide maintenance in this setting. Patients and Methods The meta-analysis was conducted using primary-source patient-level data and documentation from three RCTs (Cancer and Leukemia Group B 100104, Gruppo Italiano Malattie Ematologiche dell'Adulto RV-MM-PI-209, and Intergroupe Francophone du Myélome 2005-02) that met the following prespecified inclusion criteria: an RCT in patients with NDMM receiving ASCT followed by lenalidomide maintenance versus placebo or observation with patient-level data available and achieved database lock for primary efficacy analysis. Results Overall, 1,208 patients were included in the meta-analysis (605 patients in the lenalidomide maintenance group and 603 in the placebo or observation group). The median PFS was 52.8 months for the lenalidomide group and 23.5 months for the placebo or observation group (hazard ratio, 0.48; 95% CI, 0.41 to 0.55). At a median follow-up time of 79.5 months for all surviving patients, the median OS had not been reached for the lenalidomide maintenance group, whereas it was 86.0 months for the placebo or observation group (hazard ratio, 0.75; 95% CI, 0.63 to 0.90; P = .001). The cumulative incidence rate of a second primary malignancy before disease progression was higher with lenalidomide maintenance versus placebo or observation, whereas the cumulative incidence rates of progression, death, or death as a result of myeloma were all higher with placebo or observation versus lenalidomide maintenance. Conclusion This meta

    The efficacy and safety of lenalidomide maintenance therapy after ASCT in patients with MM has been in question. In order to address the issue, we conducted a meta-analysis of two randomized double-blind placebo-controlled studies encompassing 1074 patients treated with lenalidomide or placebo maintenance therapy after ASCT. The predominant clinical outcomes of interest were overall survival (OS), progression-free survival (PFS), and adverse events. There was a marked benefit in PFS with lenalidomide (Odds Ratio [OR] = 2.5, 95% confidence interval [CI] = 1.93 to 3.24). There was statistically non-significant tendency toward benefit in OS with lenalidomide (OR = 1.21, 95% CI = 0.65 to 2.24). For adverse events, more patients in lenalidomide treatment arm experienced neutropenia (OR = 4.88, 95% CI = 3.67 to 6.50), infection (OR = 2.82, 95% CI = 1.67 to 4.73), hematologic cancers (OR = 3.31, 95% CI = 1.30 to 8.41), and solid tumors (OR = 2.24, 95% CI = 1.01 to 4.98). No significant differences were seen with deep vein thrombosis (OR = 2.15, 95% CI = 0.92 to 5.06), peripheral neuropathy (OR = 1.50, 95% CI = 0.53 to 4.25), thrombocytopenia (OR = 1.05, 95% CI = 0.12 to 9.54), and anemia (OR = 1.36, 95% CI = 0.02 to 83.86). Based on these results, we conclude that lenalidomide maintenance therapy for patients with MM after ASCT was effective in the improvement of PFS. However, treatment-related adverse events must be close monitored. Although there was a trend for increased OS with lenalidomide, there was no statistically significant difference in OS between lenalidomide maintenance therapy arm and placebo maintenance therapy arm. Therefore, longer follow-up and additional high quality RCTs were needed to evaluate the effects of lenalidomide maintenance on OS.

    Full Text Available Myelodysplastic syndrome (MDS is a clonal bone marrow disorder characterized by ineffective hematopoiesis. It is characterized by peripheral blood cytopenia and significant risk of progression to acute myeloid leukemia result. Deletion of the long arm of chromosome 20 (20q deletion is present in 3–7% of patients with MDS. Lenalidomide is an immunomodulatory agent with antiangiogenic activity. It is FDA approved for the treatment of anemia in patients with low or int-1 risk MDS with chromosome 5q deletion with or without additional cytogenetic abnormalities. Study of lenalidomide in patients with MDS without 5q deletion but other karyotypic abnormalities demonstrated meaningful activity in transfusion dependent patients; however, response of patients with isolated 20q deletion to lenalidomide is not known. We are reporting a patient with 20q deletion MDS treated with lenalidomide after he failed to respond to azacytidine; to our knowledge this is the first report of a patient with isolated 20q deletion treated with lenalidomide.

    ABSTRACT We investigated the cytotoxic interactions of romidepsin, a histone deacetylase inhibitor, and lenalidomide, an immunomodulatory agent, in a T-cell lymphoma preclinical model. Hut-78 and Karpas-299 cells were treated with romidepsin and lenalidomide alone and in combination. The interaction between romidepsin and lenalidomide was evaluated by the Chou–Talalay method, and cell viability and clonogenicity were also evaluated. Apoptosis, reactive oxygen species (ROS) levels, and cell cycle distribution were determined by flow cytometry. ER stress, caspase activation, and the AKT, MAPK/ERK, and STAT-3 pathways were analyzed by Western blot. Combination treatment with romidepsin and lenalidomide had a synergistic effect in Hut-78 cells and an additive effect in Karpas-299 cells at 24 hours and did not decrease the viability of normal peripheral blood mononuclear cells. This drug combination induced apoptosis, increased ROS production, and activated caspase-8, −9, −3 and PARP. Apoptosis was associated with increased hallmarks of ER stress and activation of UPR sensors and was mediated by dephosphorylation of the AKT, MAPK/ERK, and STAT3 pathways.The combination of romidepsin and lenalidomide shows promise as a possible treatment for T-cell lymphoma. This work provides a basis for further studies. PMID:27657380

    The aim of this study was to evaluate the efficacy and adverse effects of lenalidomide in the treatment of intermediate-1 risk non-5q deletion [non-del (5q)] myelodysplastic syndrome (MDS). A total of 30 patients with MDS were classified through G-banding chromosome karyotype analysis and fluorescence in situ hybridization (FISH). According to the International Prognostic Scoring System scores, among the 30 patients, 23 and seven cases had scores of 0.5 and 1.0, respectively. Lenalidomide (Revlimid(®)), 10 mg/day) was administered for 21 days every 28 days. All 30 cases were treated with lenalidomide for at least three cycles, including 20 cases with four cycles. The patients did not require erythropoietin, cyclosporine or iron chelation treatments. Statistical analysis was performed using SPSS statistical software version 13.0, and comparisons among groups were conducted using a t-test. The efficacy of lenalidomide was demonstrated in patients with intermediate-1 risk non-del (5q) MDS. Peripheral blood cell counts were improved following treatment, and absolute neutrophil, haemoglobin and platelet counts increased following 2-4 cycles of treatment. All patients became stable having undergone three cycles of treatment; however, 17 patients with chromosomal abnormalities had no cytogenetic response to the treatment, as confirmed through the FISH test. Patients with intermediate-1 risk non-del (5q) MDS treated with lenalidomide did not achieve complete haematological remission, although they demonstrated haematological improvement.

    The purpose of this study is to enhance the dissolution rate of prednisone by co-grinding with Neusilin to form a complex that can be incorporated into a mini-tablet formulation for pediatrics. Prednisone-Neusilin complex was co-grinded at various ratios (1:1, 1:3, 1:5, and 1:7). The physicochemical properties of the complex were characterized by various analytical techniques including: differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), scanning electron microscope (SEM), particle size, surface area, solubility, and dissolution rate. The co-grinded prednisone-Neusilin complex (1:7) was blended with other excipients and was formulated into a 2-mm diameter mini-tablet. The mini-tablets were further evaluated for thickness, weight, content uniformity, and dissolution rate. To improve taste masking and stability, mini-tablets were coated by dip coating with Eudragit® EPO solution. DSC and XRPD results showed that prednisone was transformed from crystalline state into amorphous state after co-grinding with Neusilin. Particle size, surface area, and SEM results confirmed that prednisone was adsorbed to Neusilin's surface. Co-grinded prednisone-Neusilin complex (1:7) had a solubility of 0.24 mg/mL and 90% dissolved within 20 min as compared to crystalline prednisone which had a solubility of 0.117 mg/mL and 30% dissolved within 20 min. The mini-tablets containing co-grinded prednisone-Neusilin complex (1:7) exhibited acceptable physicochemical and mechanical properties including dissolution rate enhancement. These mini-tablets were successfully dip coated in Eudragit® EPO solution to mask the taste of the drug during swallowing. This work illustrates the potential use of co-grinded prednisone-Neusilin to enhance solubility and dissolution rate as well as incorporation into a mini-tablet formulation for pediatric use.

    Prednisolone and prednisone are integral components of induction and maintenance immunosuppressive regimens in solid organ transplantation. The pharmacokinetics of these agents are extremely complex. Prednisolone is the active drug moiety while prednisone is both a pro-drug and inactive metabolite of prednisolone. Within the dosage range used in transplantation, prednisolone and prednisone exhibit concentration-dependent non-linear pharmacokinetics when parameters are measured with reference to total drug concentration. Dose dependency disappears when free (unbound) prednisolone is measured. Altered organ function, changing biochemistry and use of a number of concomitant medicines in transplantation appear to lead to pharmacokinetic differences in transplant recipients compared with other patient groups. Greater than threefold variability in dose-adjusted exposure to total prednisolone in transplant recipients is evident. Time post-transplant, hepatic and renal dysfunction, patient age, sex, bodyweight, serum albumin concentration, concomitant medication exposure, various disease states and genetic polymorphisms in metabolic enzymes and drug transporters have sometimes been associated with prednisolone pharmacokinetic variability. The clinical impact of corticosteroid therapy on the disposition of ciclosporin, tacrolimus and sirolimus and the impact of different immunosuppressant therapy combinations on prednisolone exposure needs to be further elucidated. Patient response patterns to prednisolone are consistent with delayed and indirect mechanisms of corticosteroid action involving modification of nuclear transcription and protein synthesis. Many adverse effects have been linked with prednisolone and prednisone therapy, but not all of these have been investigated thoroughly in transplant populations. Dyslipidaemia, growth restriction, diabetogenesis, hypertension and cataracts are well studied toxicities. Evidence is less clear for prednisolone

    We report three cases of massive chest wall plasmacytoma, each greater than 10 cm in diameter, without evidence of overt myeloma, whom we treated with a combination of VAD chemotherapy consolidated by high-dose melphalan and autologous peripheral blood stem cell transplantation and radical radiotherapy. All three patients completed all components of their therapy without experiencing any major side effects and one patient has had a durable remission. The other two patients have had disease progression but at sites other than the original tumour.

    Background Isolated limb infusion (ILI) with melphalan is a minimally invasive, effective treatment for in transit melanoma. We hypothesized that burden of disease (BOD) would correlate to treatment response. Methods We retrospectively analyzed a prospectively collected database from two academic centers. BOD was stratified as high or low (less than 10 lesions, none > 2cm). Response rates were measured 3 months post-ILI. Multivariable analysis (MV) was used to evaluate the association between the response rate and BOD. Kaplan-Meier methods with log-rank tests and multivariable Cox proportional hazard models were used to analyze overall survival (OS) and progression free survival (PFS) Results Sixty (38%) patients had low and 100 (62%) high BOD. Patients with low BOD had an overall response rate (ORR) of 73%, and 50% CR; compared to an ORR of 47% and 24% CR in patients with high BOD (p= 0.002). MV analysis of preoperative, intraoperative, and postoperative parameters showed no significant impact on 3-month response. Patients with a CR at 3 months demonstrated improved PFS over the remainder of the cohort, but OS was equal. Low BOD patients had an increased median PFS of 6.9 vs 3.8 months (p= 0.047), and a non-statistically significantly increased median OS, 38.4 vs. 30.9 months (p=0.146). Conclusions Lower BOD is associated with an increased ORR and CR rate with statistically significantly improved PFS in patients undergoing ILI for in transit extremity melanoma. BOD provides useful prognostic information for patient counseling and serves as a marker to stratify patient risk groups. PMID:25192683

    Unresectable liver metastases of colorectal cancer can be treated with systemic chemotherapy, aiming to limit the disease, extend survival or turn unresectable metastases into resectable ones. Some patients however, suffer from side effects or progression under systemic treatment. For patients with metastasized uveal melanoma there are no standard systemic therapy options. For patients without extrahepatic disease, isolated liver perfusion (IHP) may enable local disease control with limited systemic side effects. Previously, this was performed during open surgery with satisfying results, but morbidity and mortality related to the open procedure, prohibited a widespread application. Therefore, percutaneous hepatic perfusion (PHP) with simultaneous chemofiltration was developed. Besides decreasing morbidity and mortality, this procedure can be repeated, hopefully leading to a higher response rate and improved survival (by local control of disease). During PHP, catheters are placed in the proper hepatic artery, to infuse the chemotherapeutic agent, and in the inferior caval vein to aspirate the chemosaturated blood returning through the hepatic veins. The caval vein catheter is a double balloon catheter that prohibits leakage into the systemic circulation. The blood returning from the hepatic veins is aspirated through the catheter fenestrations and then perfused through an extra-corporeal filtration system. After filtration, the blood is returned to the patient by a third catheter in the right internal jugular vein. During PHP a high dose of melphalan is infused into the liver, which is toxic and would lead to life threatening complications when administered systemically. Because of the significant hemodynamic instability resulting from the combination of caval vein occlusion and chemofiltration, hemodynamic monitoring and hemodynamic support is of paramount importance during this complex procedure.

    The Cul4-Rbx1-DDB1-Cereblon E3 ubiquitin ligase complex is the target of thalidomide, lenalidomide and pomalidomide, therapeutically important drugs for multiple myeloma and other B-cell malignancies. These drugs directly bind Cereblon (CRBN) and promote the recruitment of substrates Ikaros (IKZF1) and Aiolos (IKZF3) to the E3 complex, thus leading to substrate ubiquitination and degradation. Here we present the crystal structure of human CRBN bound to DDB1 and the drug lenalidomide. A hydrophobic pocket in the thalidomide-binding domain (TBD) of CRBN accommodates the glutarimide moiety of lenalidomide, whereas the isoindolinone ring is exposed to solvent. We also solved the structures of the mouse TBD in the apo state and with thalidomide or pomalidomide. Site-directed mutagenesis in lentiviral-expression myeloma models showed that key drug-binding residues are critical for antiproliferative effects.

    Thalidomide and its derivatives, lenalidomide and pomalidomide, are immune modulatory drugs (IMiDs) used in the treatment of haematologic malignancies. IMiDs bind CRBN, the substrate receptor of the CUL4-RBX1-DDB1-CRBN (also known as CRL4(CRBN)) E3 ubiquitin ligase, and inhibit ubiquitination of endogenous CRL4(CRBN) substrates. Unexpectedly, IMiDs also repurpose the ligase to target new proteins for degradation. Lenalidomide induces degradation of the lymphoid transcription factors Ikaros and Aiolos (also known as IKZF1 and IKZF3), and casein kinase 1α (CK1α), which contributes to its clinical efficacy in the treatment of multiple myeloma and 5q-deletion associated myelodysplastic syndrome (del(5q) MDS), respectively. How lenalidomide alters the specificity of the ligase to degrade these proteins remains elusive. Here we present the 2.45 Å crystal structure of DDB1-CRBN bound to lenalidomide and CK1α. CRBN and lenalidomide jointly provide the binding interface for a CK1α β-hairpin-loop located in the kinase N-lobe. We show that CK1α binding to CRL4(CRBN) is strictly dependent on the presence of an IMiD. Binding of IKZF1 to CRBN similarly requires the compound and both, IKZF1 and CK1α, use a related binding mode. Our study provides a mechanistic explanation for the selective efficacy of lenalidomide in del(5q) MDS therapy. We anticipate that high-affinity protein-protein interactions induced by small molecules will provide opportunities for drug development, particularly for targeted protein degradation.

    The use of pomalidomide after lenalidomide and (or) bortezomib failure in patients with multiple myeloma is not clearly clarified in clinical practice. We sought to compile the available clinical reports to better understand the effectiveness of pomalidomide after failure of lenalidomide and (or) bortezomib. We searched published reports including pomalidomide, lenalidomide and (or) bortezomib. Seven reports were identified. Pomalidomide-based regimen was pomalidomide plus low-dose dexamethasone (POM + LoDEX). Six randomized controlled trials enrolling a total of 641 patients that evaluated the treatment effects of pomalidomide after lenalidomide and (or) bortezomib failure in patients with multiple myeloma were included. Pooled results showed that the overall response rate (ORR) was 31% in the POM + LoDEX group. Analysis of heterogeneity showed very little (p = 0.997, I(2)  = 0%), suggesting that response rates of POM + LoDEX therapy were consistent across those included trials. Stable disease was achieved in 40% of 603 patients (heterogeneity: p = 0.980, I(2)  = 0%). In those >65 years, overall response was achieved in 32% of 71 patients (heterogeneity: p = 0.77, I(2)  = 0%). POM + LoDEX showed promising activity in the 95 patients with high-risk cytogenetic abnormalities: ORR was 27% (heterogeneity: p = 0.97, I(2)  = 0%). In the pooled analysis, toxicity consisted primarily of myelosuppression: Grade 3 or 4 neutropenia was seen in 53% (heterogeneity: p = 0.857, I(2)  = 0%). Pomalidomide may produce clinical benefits in patients who had shown refractory on prior lenalidomide and (or) bortezomib therapy. Moreover, elder patients and high-risk cytogenetic abnormalities were not negative predictors for pomalidomide response after lenalidomide and (or) bortezomib failure.

    Full Text Available Acute pancreatitis and diabetic ketoacidosis are unusual adverse events following chemotherapy based on L-asparaginase and prednisone as support treatment for acute lymphoblastic leukemia. We present the case of a 16-year-old Hispanic male patient, in remission induction therapy for acute lymphoblastic leukemia on treatment with mitoxantrone, vincristine, prednisone, and L-asparaginase. He was hospitalized complaining of abdominal pain, nausea, and vomiting. Hyperglycemia, acidosis, ketonuria, low bicarbonate levels, hyperamylasemia, and hyperlipasemia were documented, and the diagnosis of diabetic ketoacidosis was made. Because of uncertainty of the additional diagnosis of acute pancreatitis as the cause of abdominal pain, a contrast-enhanced computed tomography was performed resulting in a Balthazar C pancreatitis classification.

    The Kasabach-Merritt syndrome is characterized by thrombocytopenia and localized coagulopathy associated with a hemangioma. Most techniques applied to eradicate the tumor or accelerate its involution (surgery, radiation therapy, embolization) are invasive and require transfusion of large amounts of blood products. In some cases, medical treatment is the only alternative. Efficacy of steroids and antifibronolytic agents has already been described, but even this approach is associated with the administration of blood products. We report two cases of infants with Kasabach-Merritt syndrome associated with cardiac and hepatic hemangiomas. At admission, both had signs of cardiac failure. They were successfully treated with prednisone and epsilon-aminocaproic acid (EACA). Blood products were not required once the diagnosis was made. These observations have important implications for the management of patients with Kasabach-Merritt syndrome because they show that even in severe cases blood transfusions can be avoided by the use of prednisone and EACA.

    The quantification of prednisone in tablets was performed using partial least squares (PLS) models based on FTIR-attenuated total reflection (ATR) and FT-Raman spectra. To compare the predictive ability of these models, the relative standard error of prediction (RSEP) values were calculated. In the case of prednisone determination from the FT-Raman data, RSEP values of 3.1 and 3.2% for the calibration and validation data sets were obtained. For FTIR-ATR models, which were constructed using five spectra for each sample, these errors amounted to 2.6 and 2.9%, respectively. Four commercial products containing 1, 5, 10, and 20 mg prednisone/tablet were quantified. Concentrations derived from the elaborated models correlated strongly with the results of reference analyses and with the declared values (in parentheses). The analyses gave recoveries of 100.0-101.6% (100.1-103.0%) and 98.1-103.2% (100.4-102.9%) for FTIR-ATR and FT-Raman data, respectively. A successful quantification of prednisolone in tablets containing 5 mg active ingredient/tablet was also performed using the PLS model, which was based on FTIR-ATR spectra, with a recovery of 99.8 (98.8%). Both reported spectroscopic techniques can be used as fast and convenient alternatives to the standard pharmacopeial methods of prednisone and prednisolone quantification in solid dosage forms. However, in the case of FTIR-ATR spectroscopy, it is necessary to repeat measurements several times to obtain sufficiently low quantification errors.

    Therapeutic results of relapsed/refractory chronic lymphocytic leukemia (CLL) are very disappointing at present. Lenalidomide has been proved to be effective for relapsed/refractory CLL as a single agent or in combination with various chemo-immunotherapeutic regimens. However, current clinical experience in its usage is still limited. Because of existing considerable variability in different studies, a systematic review and meta-analysis was conducted to describe overall response rate (ORR) of lenalidomide in patients with relapsed/refractory CLL. Pooled estimate of cumulative prevalence of total ORR was 42.23 % (95 % confidence interval [CI], 32.49-52.61 %), while pooled ORR in regimen with lenalidomide plus anti-CD20 monoclonal antibody (mAbs) and lenalidomide mono-therapy were 60.01 % (95 % CI, 53.86-65.86 %) and 24.38 % (95 % CI, 16.15-35.06 %), respectively. There was no significant difference between L + R (lenalidomide plus rituximab) group and L + O (lenalidomide plus ofatumumab) group, with pooled ORR of 66.38 % (95 % CI, 57.96-73.87 %) and 57.40 % (95 % CI, 46.46-67.65 %), respectively. When co-administrated with anti-CD20 mAbs, dosage of lenalidomide was not the key factor of ORR in combination therapy. Pooled ORR of patient with high-risk cytogenetic in L + anti-CD20 mAbs group was 56.74 % (95 % CI, 45.53-67.30 %). In comparison with patients without high-risk cytogenetic receiving the same treatment regimen, no significant difference was observed, with relative risk (RR) of 0.87 (95 % CI 0.68-1.11). Our finding demonstrated that lenalidomide plus anti-CD20 mAbs could be an efficient therapy regimen for relapsed/refractory CLL patients, especially for those with high-risk cytogenetic factor.

    Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease of the skin and mucous membranes. Most cases occur in adults; cases in children are rare. This report describes the clinical presentations and treatment responses of three children with PV, as confirmed according to histology and indirect immunofluorescence studies. In all three cases, oral prednisone used in conjunction with mycophenolate mofetil (MMF) resulted in complete clinical remission, during which all pharmacotherapy was successfully discontinued. Resolution of the skin and mucosal blistering tended to occur quickly with prednisone, and after initiation of treatment with MMF, discontinuation of all pharmacotherapy was achieved within a range of 10 to 30 months in the three patients. One patient experienced a recurrence of genital lesions 19 months after discontinuation of therapy, but the condition remitted within 2 weeks with topical corticosteroid therapy. At the time of this report, the duration of complete remission ranged from 6 to 19 months. In summary, combination therapy with prednisone and MMF for pediatric PV appears to be a safe and effective approach that is associated with durable remission.

    Full Text Available We conducted this randomized trial to investigate the efficacy and safety of rapamycin treatment in adults with chronic immune thrombocytopenia (ITP. Eighty-eight patients were separated into the control (cyclosporine A plus prednisone and experimental (rapamycin plus prednisone groups. The CD4+CD25+CD127low regulatory T (Treg cells level, Foxp3 mRNA expression, and the relevant cytokines levels were measured before and after treatment. The overall response (OR was similar in both groups (experimental group versus control group: 58% versus 62%, P=0.70. However, sustained response (SR was more pronounced in the experimental group than in the control group (68% versus 39%, P<0.05. Both groups showed similar incidence of adverse events (7% versus 11%, P=0.51. As expected, the low pretreatment baseline level of Treg cells was seen in all patients (P<0.001; however, the experimental group experienced a significant rise in Treg cell level, and there was a strong correlation between the levels of Treg cells and TGF-beta after the treatment. In addition, the upregulation maintained a stable level during the follow-up phase. Thus, rapamycin plus low dose prednisone could provide a new promising option for therapy of ITP.

    Diatoms are porous silica-based materials obtained from single cell photosynthetic algae. Despite low cost, easy purification process, environmentally safe properties, and rapidly increasing potentials for medical applications, the cytotoxicity of diatoms and the effect on drug permeation of oral formulations have not been studied so far. Herein, we have evaluated the potential of diatom silica microparticles (DSMs) for the delivery of mesalamine and prednisone, which are two commonly prescribed drugs for gastrointestinal (GI) diseases. Transmission electron microscopy analysis of the morphological surface changes of Caco-2/HT-29 monolayers and the cell viability data in colon cancer cells (Caco-2, HT-29 and HCT-116) showed very low toxicity of diatoms at concentrations up to 1000 μg/mL. The mesalamine and prednisone release under simulated GI conditions indicated prolonged release of both drugs from the diatoms. Furthermore, drug permeation across Caco-2/HT-29 co-culture monolayers demonstrated that diatoms are capable to enhance the drug permeability. Overall, this study evaluated DSMs' cytotoxicity in colon cancer cells and the effect of DSMs on drug permeability across Caco-2/HT-29 monolayers. Our results demonstrate that DSMs can be considered as a non-cytotoxic biomaterial with high potential to improve the mesalamine and prednisone bioavailability by sustaining the drug release and enhancing drug permeability.

    Corticosteriods are usually given for management of Graves' ophthalmopathy, but they have many and serious side-effects. By comparison, retrobulbar irradiation is well tolerated, although its efficacy has been evaluated only in uncontrolled studies. Therefore, the authors did a double-blind randomized trial, in which 28 patients with moderately severe Graves' ophthalmopathy were treated with a 3-month course of oral prednisone and sham irradiation, and 28 received retrobulbar irradiation (20 Gy) and placebo capsules. Therapeutic outcome, assessed twenty-four weeks after the start of treatment, was determined by the change in the highest NOSPECS class. A successful outcome was observed in 14 prednisone-treated and in 13 irradiated patients. Responders to treatment (but not nonresponders) in both groups showed improvements in total and subjective eye score and a decrease in eye-muscle volume. Response to either treatment was due largely to changes in soft-tissue involvement and eye-muscle motility. Radiotherapy and oral prednisone appear to be equally effective as initial treatment in patients with moderately severe Graves' ophthalmopathy. In view of its better tolerability, radiotherapy should be considered the treatment of first choice.

    This study has retrospectively analyzed the efficacy of single-agent prednisone, usually given after failure of other therapies, in 30 patients with myelofibrosis (MF) and severe anemia. Initial dose was 0.5-1 mg/kg daily, with tapering to the minimum effective dose in responders. Twelve patients (40%) achieved anemia response according to the revised International Working Group for Myelofibrosis Research and Treatment criteria, after a median time of 1.1 months on treatment. Median response duration was 12.3 months. Patients with constitutional symptoms or > 2% circulating blasts had a trend for a lower response rate. A platelet increase > 50 × 10(9)/L was observed in three out of 11 patients with baseline counts prednisone start was significantly longer in anemia responders (5.0 years, 95% CI = 3.5-6.5, vs 1.5 years, 95% CI = 0.2-2.8; p = 0.002). Prednisone can improve the anemia and thrombocytopenia in selected MF patients after failure to standard therapies.

    Previous findings showed that the anticancer drugs p-N,N-bis(2-chloroethyl) amino-l-phenylalanine (melphalan, MEL) and p-N,N-bis(2-chloroethyl)aminophenylbutyric acid (chlorambucil, CAB) belonging to the nitrogen mustard group, in addition to their clastogenic activity, also exert aneugenic potential, nondisjunction and chromosome delay. Their aneugenic potential is mainly mediated through centrosome defects. To further investigate their aneugenicity we (a) studied whether apoptosis is a mechanism responsible for the elimination of damaged cells generated by MEL and CAB and (b) investigated if proteins that regulate chromosome segregation are involved in the modulation of their aneugenic potential. Apoptosis was studied by Annexin-V/Propidium Iodide staining and fluorescence microscopy. The involvement of apoptosis on the exclusion of cells with genetic damage and centrosome disturbances was analyzed by DAPI staining and immunofluorescence of β- and γ-tubulin in the presence of pan-caspase inhibitor. The expressions of Aurora-A, Aurora-B, survivin and γ-tubulin were studied by western blot. We found that (a) apoptosis is not the mechanism of choice for selectively eliminating cells with supernumerary centrosomes, and (b) the proteins Aurora-A, Aurora-B and survivin are involved in the modulation of MEL and CAB aneugenicity. These findings are important for the understanding of the mechanism responsible for the aneugenic activity of the anticancer drugs melphalan and chlorambucil.

    We evaluated the effect of prednisone on midazolam and odanacatib pharmacokinetics. In this open-label, 2-period crossover study in healthy male subjects, midazolam 2 mg was administered (Day -1) followed by odanacatib 50 mg (Day 1) during Part 1. In Period 2, prednisone 10 mg once daily (qd) was administered on Days 1-28; odanacatib was co-administered on Day 14 and midazolam 2 mg was co-administered on Days 1 and 28. Subjects were administered midazolam 2 mg on Days 42 and 56. Safety and tolerability were assessed throughout the study. A physiologically-based pharmacokinetic (PBPK) model was also built. There were 15 subjects enrolled; mean age was 31 years. The odanacatib AUC(0- ∞) GMR (90% CI) [odanacatib + prednisone (Day 14, Period 2)/odanacatib alone (Day 1, Period 1] was 1.06 (0.96, 1.17). AUC(0-∞) GMR (90%CI) [midazolam + prednisone (Day 28, Period 2)/midazolam alone (Day -1, Period 1] was 1.08 (0.93,1.26). There were no serious AEs or AEs leading to discontinuation. PBPK modeling showed that prednisone does not cause significant effects on the exposure of sensitive CYP3A4 substrates in vivo at therapeutic doses. Co-administration of prednisone 10 mg qd had no effect on pharmacokinetics of either odanacatib 10 mg or midazolam 2 mg.

    A 75-year-old woman was diagnosed with symptomatic IgG-l multiple myeloma (good-prognosis group) in December 2010. A stringent complete response (sCR) was achieved by using induction therapy with bortezomib (BOR, Velcade®)+ dexamethasone (DEX)(VD) and consolidation therapy with BOR+lenalidomide (LEN, Revlimid®)+DEX(VRD). Although maintenance therapy with Revlimid®+DEX(Rd) was initiated, a pancreatic neuroendocrine tumor was detected in April 2013. Therefore, LEN was discontinued and distal pancreatectomy was performed in September 2013. Because discontinuation of LEN was followed by exacerbation of myeloma, LEN was resumed with the consent of the patient; however, she became resistant to the treatment. The course of this case suggests that some patients must continue to receive LEN even if a sCR is achieved.

    Lenalidomide (Revlimid(®)), a thalidomide analogue, is an orally administered second generation immunomodulator with anti-angiogenic, antineoplastic, anti-inflammatory and pro-erythropoietic properties. It is approved for the treatment of patients with transfusion-dependent anaemia due to International Prognostic Scoring System low- or intermediate-1-risk myelodysplastic syndrome (MDS) associated with either chromosome 5q deletion [del(5q)] with or without additional cytogenetic abnormalities (US, Japan and Switzerland etc.), or with an isolated del(5q) cytogenetic abnormality when other therapeutic options are insufficient or inadequate (EU) [featured indication]. In a randomized, double-blind, multicentre, registrational trial (MDS-004; n = 205) in this patient population, a significantly higher proportion of lenalidomide recipients than placebo recipients achieved red blood cell transfusion independence for ≥26 consecutive weeks (primary endpoint for efficacy) and cytogenetic responses. The erythroid response to lenalidomide was accompanied by an increase in the haemoglobin levels. These efficacy outcomes are generally consistent with those seen in an earlier noncomparative registrational trial (MDS-003; n = 148). In MDS-004, lenalidomide also significantly improved health-related quality of life compared with placebo at 12 weeks. Retrospective analyses that compared outcomes between lenalidomide-treated patients with low- or intermediate-1-risk del(5q) MDS and multicentre registry cohorts showed that lenalidomide treatment did not appear to increase the risk of progression to acute myeloid leukaemia. Lenalidomide had a manageable safety profile in the registrational trials, with ≤20 % of patients discontinuing treatment because of adverse events. The most common adverse events (incidence ≥20 %) occurring in lenalidomide recipients were thrombocytopenia and neutropenia, which were generally managed by dosage reductions and/or interruptions, and

    The introduction of novel immunomodulatory drugs (IMiDs) has dramatically improved the survival of patients with multiple myeloma (MM). While it has been shown that patients with specific cytogenetic subtypes, namely t(4;14), have the best outcomes when treated with bortezomib-based regimens, the relationship between cytogenetic subtypes and response to IMiDs remains unclear. Using DNA synthesis assays, we investigated the relationship between cytogenetic subtype and lenalidomide response in a representative panel of human myeloma cell lines (HMCLs). We examined HMCL protein expression levels of the lenalidomide target cereblon (CRBN) and its downstream target interferon regulatory factor-4 (IRF4), which have previously been shown to be predictive of lenalidomide response in HMCLs. Our results reveal that lenalidomide response did not correlate with specific cytogenetic translocations. There were distinct groups of lenalidomide-responsive and non-responsive HMCLs, as defined by inhibition of cellular proliferation; notably, all of the hyperdiploid HMCLs fell into the latter category. Repeated dosing of lenalidomide significantly lowered the IC50 of the responsive HMCL ALMC-1 (IC50 = 2.6 μm vs. 0.005 μm, P 0.05). Moreover, no association was found between lenalidomide responsiveness and CRBN and IRF4 expression. Our data indicate that lenalidomide sensitivity is independent of cytogenetic subtype in HMCLs. While CRBN and IRF4 have been shown to be associated with response to lenalidomide in patients, these findings do not translate back to HMCLs, which could be attributable to factors present in the bone marrow microenvironment.

    mAbs can induce antibody-dependent cellular cytotoxicity (ADCC) via the innate immune system's ability to recognize mAb-coated cancer cells and activate immune effector cells. Lenalidomide is an immunomodulatory agent with the capacity to stimulate immune cell cytokine production and ADCC activity. This phase I trial evaluated the combination of cetuximab with lenalidomide for the treatment of advanced colorectal and head and neck squamous cell cancers (HNSCC). This trial included patients with advanced colorectal cancer or HNSCC. Treatment consisted of cetuximab 500 mg/m(2) i.v. every two weeks with lenalidomide given orally days 1-21 on a 28-day cycle. Three dose levels of lenalidomide were evaluated (15, 20, 25 mg). Correlative studies included measurement of ADCC, FcγRIIIA polymorphism genotyping, measurement of serum cytokine levels, and flow cytometric analysis of immune cell subtypes. Twenty-two patients were enrolled (19 colorectal cancer, 3 HNSCC). Fatigue was the only dose-limiting toxicity. One partial response was observed and 8 patients had stable disease at least 12 weeks. The recommended phase II dose is cetuximab 500 mg/m(2) with lenalidomide 25 mg daily, days 1-21. Correlative studies demonstrated a dose-dependent increase in natural killer cytotoxic activity with increasing doses of lenalidomide. Cetuximab and lenalidomide were well tolerated. There was a lenalidomide dose-dependent increase in ADCC with higher activity in patients enrolled in cohort 3 than those enrolled in cohorts 1/2. Although response was not a primary endpoint, there was evidence of antitumor activity for the combination therapy. Further investigation of lenalidomide as an immunomodulator in solid tumors is warranted. Mol Cancer Ther; 15(9); 2244-50. ©2016 AACR.

    Lenalidomide and its related 'analogues' modulate the substrate specificity of the CRL4(CRBN) E3 ubiquitin ligase complex. Polyubiquitination and subsequent proteasomal degradation of IKZF1 and IKZF3 in multiple myeloma and CK1α in del(5q) MDS has recently been linked to therapeutic efficacy of this class of compounds. Harnessing ubiquitin ligase substrate specificity, may in time facilitate the degradation of other 'undruggable' proteins and allow for separation of detrimental side effects of IMiD compounds from those associated with therapeutic efficacy.

    5q-syndrome is a special subgroup of myelodysplastic syndrome in terms of follow-up and treatment. Lenalidomide is an immunomodulatory drug that is frequently used in the treatment of multiple myeloma. Some clinical studies have shown that lenalidomide treatment is effective in 5q syndrome and significantly decreases the transfusion dependency in these patients. In this paper, we would like to share a dramatic response of lowered transfusion dependency after treatment with low-dose lenalidomide in a patient who received myelodysplastic syndrome diagnosis and isolated 5q anomaly in our clinic.

    Toxicity of the oral and gastrointestinal mucosa induced by high-dose melphalan is a clinical challenge with no documented prophylactic interventions or predictive tests. The aim of this study was to describe molecular changes in human oral mucosa and to identify biomarkers correlated with the grade of clinical mucositis. Ten patients with multiple myeloma (MM) were included. For each patient, we acquired three buccal biopsies, one before, one at 2 days, and one at 20 days after high-dose melphalan administration. We also acquired buccal biopsies from 10 healthy individuals that served as controls. We analyzed the biopsies for global gene expression and performed an immunohistochemical analysis to determine HLA-DRB5 expression. We evaluated associations between clinical mucositis and gene expression profiles. Compared to gene expression levels before and 20 days after therapy, at two days after melphalan treatment, we found gene regulation in the p53 and TNF pathways (MDM2, INPPD5, TIGAR), which favored anti-apoptotic defense, and upregulation of immunoregulatory genes (TREM2, LAMP3) in mucosal dendritic cells. This upregulation was independent of clinical mucositis. HLA-DRB1 and HLA-DRB5 (surface receptors on dendritic cells) were expressed at low levels in all patients with MM, in the subgroup of patients with ulcerative mucositis (UM), and in controls; in contrast, the subgroup with low-grade mucositis (NM) displayed 5-6 fold increases in HLA-DRB1 and HLA-DRB5 expression in the first two biopsies, independent of melphalan treatment. Moreover, different splice variants of HLA-DRB1 were expressed in the UM and NM subgroups. Our results revealed that, among patients with MM, immunoregulatory genes and genes involved in defense against apoptosis were affected immediately after melphalan administration, independent of the presence of clinical mucositis. Furthermore, our results suggested that the expression levels of HLA-DRB1 and HLA-DRB5 may serve as potential

    Less toxic and more active treatments are needed for indolent lymphomas as there is no curative treatment, and patients eventually die due to complications related to their disease. The purpose of the present study was to assess the antitumour activity of the combination of low doses of Enzastaurin and Lenalidomide (Revlimid) on B-lymphoma cell lines. The combination of Enzastaurin and Lenalidomide, at doses as low as 1 μM, showed strong synergism against indolent lymphomas by reducing cell growth, producing an increase in G0-G1 phase followed by significant decrease in S phase, increasing apoptosis, and inhibiting PI3K/AKT, PKC and MAPK/ERK pathways. These preclinical findings, together with promising results obtained with Lenalidomide for the treatment of non-Hodgkin lymphoma, suggest that further evaluation of the combination of Enzastaurin and Lenalidomide for the treatment of indolent lymphomas is warranted. These compounds, with a favourable toxicity profile, are not classic chemotherapeutic agents, causing severe side effects, and could be considered an example of a new innovative attempt of an anti-cancer 'soft treatment'.

    The phthalimidone derivatives EM12 and lenalidomide, which are both structurally related to thalidomide, are highly interesting drugs and very recently lenalidomide attracted great attention as an antitumor and immune-modulating drug in the therapy for multiple myeloma. EM12 and lenalidomide are chiral, and the stereogenic carbon C-3 in the piperidine-2,6-dione moiety of these phthalimidone derivatives is prone to interconversion due to keto-enol tautomerization. The knowledge of the enantiomerization barrier is mandatory for pharmacokinetic studies and to develop a tailored therapy using the enantiopure or racemic drug. Here, we used dynamic EKC in combination with direct-calculation methods to determine the enantiomerization barriers of EM12 and lenalidomide. The separations of the enantiomers of EM12 and lenalidomide were performed in 50 mM aqueous disodium hydrogen phosphate buffer at pH 8 and 50 mM aqueous sodium tetraborate buffer at pH 9.3, respectively, using 20 mg/mL heptakis-(2,3-diacetyl-6-sulfato)-β-CD as a chiral additive. Enantiomerization of the compounds during the electrokinetic chromatographic separation resulted in pronounced plateau formation between the well-separated enantiomers. Peak form analysis of the experimentally obtained interconversion profiles yielded the enantiomerization rate constants k1 of EM12 and lenalidomide as well as the kinetic activation parameters ΔG(‡), ΔH(‡‡), and ΔS(‡) of enantiomerization by the evaluation of temperature-dependent measurements. The enantiomerization barrier ΔG(‡) was determined to be 98.3 ± 1.0 kJ/mol; the activation parameters ΔH(‡) = 46.1 ± 2.4 kJ/mol and ΔS(‡) = -170 ± 61 J/(K·mol) for EM12 and ΔG(‡) = 91.5 ± 1.0 kJ/mol, ΔH(‡) = 62.4 ± 5.4 kJ/mol, and ΔS(‡) = -98 ± 7 J/(K·mol) for lenalidomide. These findings were corroborated by density functional theory calculations at the B3LYP/3-21G level of theory of the ground state and intermediates considering an

    Full Text Available Abstract Background the mainstay of treatment of polymyalgia rheumatica (PMR is oral glucocorticoids, but randomized controlled trials of treatment are lacking. As a result, there is no evidence from controlled studies on the efficacy of different initial doses or glucocorticoid tapering. The aim of this study is to test if 12.5 mg prednisone/day is an adequate starting dose in PMR and to evaluate clinical predictors of drug response. Methods 60 consecutive PMR patients were treated with a starting dose of 12,5 mg/day prednisone. Clinical, laboratory, and, in a subset of 25 patients, ultrasonographic features were recorded as possible predictors of response to prednisone. Remission was defined as disappearance of at least 75% of the signs and symptoms of PMR and normalization of ESR and CRP within the first month, a scenario allowing steroid tapering. Results 47/60 (78.3% patients responded to 12.5 mg of prednisone after a mean interval of 6.6 ± 5.2 days. In univariate analysis, body weight and gender discriminated the two groups. In multivariate analysis, the only factor predicting a good response was low weight (p = 0.004; the higher response rate observed in women was explained by their lower weight. The mean prednisone dose per kg in the responders was 0.19 ± 0.03 mg in comparison with 0.16 ± 0.03 mg for non responders (p = 0.007. Conclusions 12.5 mg prednisone is a sufficient starting dose in ¾ of PMR patients. The main factor driving response to prednisone in PMR was weight, a finding that could help in the clinical care of PMR patients and in designing prospective studies of treatment.

    Over the last 15 years, substantial progress has been made in the treatment of patients with multiple myeloma (MM). New chemotherapeutic options with the immunomodulatory drugs thalidomide and lenalidomide and with the proteasome inhibitor bortezomib have increased the response rates before and after autologous hematopoietic stem cell transplantation (ASCT). Incorporation of the novel agents into the treatment of newly diagnosed MM and at relapse is now standard of care also for patients with MM not eligible for ASCT. However, the use of thalidomide and bortezomib is frequently associated with a dose-limiting peripheral neuropathy. In order to take full advantage of the therapeutic potential, a risk assessment for neurotoxicity is needed on a case-by-case basis. This assessment includes pre-existing neurological symptoms due to the MM, any comorbidities, and past or planned treatment regimens. The aim is to achieve maximum efficacy while minimizing the risk of developing chemotherapy-induced polyneuropathy (CIPN). This requires a neurological evaluation of the patient at regular intervals, the implementation of preventive measures, and the development of validated therapeutic strategies for emerging neurotoxic side effects. This review focuses on the incidence, prevention, and management of peripheral neurotoxicity due to thalidomide, bortezomib, and lenalidomide in the treatment of MM.

    We studied T-BiRD (thalidomide [Thalomid(®)], clarithromycin [Biaxin(®)], lenalidomide [Revlimid(®)] and dexamethasone) in symptomatic, newly diagnosed multiple myeloma. In 28-day cycles, patients received dexamethasone 40 mg/day on days 1, 8, 15, 22, clarithromycin 500 mg twice daily on days 1-28; lenalidomide 25 mg/day on days 1-21; and thalidomide 100 mg/day (50 mg/day on days 1-7 of cycle 1 only) on days 1-28. Twenty-six patients received a median of 6 cycles (range 0-41). Overall response rate (ORR) was 80% for the group and 100% in 11 patients who underwent autologous stem cell transplantation as part of first-line therapy. The 4-year overall survival rate was 74.9%, and the median progression-free survival was 35.6 months. Eight patients discontinued due to regimen toxicity. Grade 3 non hematologic toxicity affected 12 patients (46.2%). T-BiRD is a highly active regimen with potential toxicity limitations. ClinicalTrials.gov identifier: NCT00538733.

    BACKGROUND Lenalidomide, an immunomodulatory agent, has activity in lymphoproliferative disorders. The authors, therefore, evaluated its effects on T-cell immunophenotype and cytokine production in patients with chronic lymphocytic leukemia (CLL). METHODS To study the immunomodulatory effects of lenalidomide in CLL, the authors recruited 24 patients with untreated CLL enrolled in a phase 2 clinical trial of lenalidomide and obtained peripheral blood specimens for immunologic studies consisting of enumeration of T cells and assessing their ability to synthesize cytokines after activation through T-cell receptor (TCR). RESULTS After 3 cycles of therapy, patients had a significant reduction in percentage (%) and absolute lymphocyte count (ALC) and an increase in percentage of T cells, percentage of activated CD8+ T cells producing IFN-γ, and percentage of regulatory T (TR) cells when compared with their respective levels before treatment. After 15 cycles of treatment, responder patients had significant reduction in percentage of lymphocytes and ALC, percentage of activated CD4+ T cells producing IL-2, IFN-γ, or TNF-α, and percentage of TR cells when compared with their perspective levels after 3 cycles of treatment. Furthermore, the numbers of activated CD4+ T cells producing IL-2, IFN-γ, or TNF-α, activated CD8+ T cells producing IFN-γ, and TR cells normalized to the range of healthy subjects. CONCLUSIONS Treatment with lenalidomide resulted in the normalization of functional T-cell subsets in responders, suggesting that lenalidomide may modulate cell-mediated immunity in patients with CLL.

    Cereblon (CRBN) has recently been identified as a target for immunomodulatory drugs (IMiDs) and its downregulation has been linked to resistance to lenalidomide. Here, we studied CRBN expression by real time polymerase chain reaction in 49 bone marrow samples of newly diagnosed patients with multiple myeloma treated with lenalidomide and dexamethasone. Median CRBN expression was 3·45 in patients who achieved complete response, and 3·75, 2·01, 0·78, and 0·70 in those with very good partial response, partial response, stable disease and progressive disease respectively. CRBN expression levels correlated significantly with response to lenalidomide treatment (r = 0·48; P CRBN with interferon regulatory factor 4 (IRF4) (P CRBN expression and response in MM patients treated with lenalidomide is shown. CRBN expression is closely associated with IRF4, which is an important target of IMiD therapy.

    Lenalidomide is approved for the treatment of transfusion-dependent (TD) del(5q) myelodysplastic syndromes (MDS). However, few data are available in patients with transfusion-independent (TI) del(5q) MDS. In the first, observational, part of this 2-part study, we assessed the impact of transfusion dependence on overall survival (OS) and non-leukemic death in untreated del(5q) MDS patients who were TD (n = 136), TI with hemoglobin (Hb) ≥10 mg/dL (n = 88), or TI with Hb lenalidomide (10 mg/day) in 12 patients with TI del(5q) MDS and Hb lenalidomide (+12.5; P = 0.020). Evaluable TI patients experienced early increases in Hb levels, and all attained an erythroid response. Our findings suggest that TI patients with moderate anemia may benefit from early treatment with lenalidomide.

    Full Text Available Thyrotoxic induced hypokalemic periodic paralysis is a rare disorder that had been described in middle-aged men, predominantly Asians and Hispanics. This case presented with generalized weakness and hypokalemia after changing prescription for levothyroxine and starting prednisone to treat upper respiratory infection in a previously asymptomatic middle-aged Hispanic male. In this paper, we will go over the clinical presentation, mechanisms, and treatment of thyrotoxic induced hypokalemic periodic paralysis. Our objectives are to identify the classic constellation of findings in thyrotoxic periodic paralysis and to recognize the importance of considering thyrotoxic periodic paralysis among patients with hypokalemia.

    Induction therapy for childhood acute lymphoblastic leukemia (ALL) traditionally includes prednisone; yet, dexamethasone may have higher antileukemic potency, leading to fewer relapses and improved survival. After a 7-day prednisone prephase, 3720 patients enrolled on trial Associazione Italiana di Ematologia e Oncologia Pediatrica and Berlin-Frankfurt-Münster (AIEOP-BFM) ALL 2000 were randomly selected to receive either dexamethasone (10 mg/m(2) per day) or prednisone (60 mg/m(2) per day) for 3 weeks plus tapering in induction. The 5-year cumulative incidence of relapse (± standard error) was 10.8 ± 0.7% in the dexamethasone and 15.6 ± 0.8% in the prednisone group (P < .0001), showing the largest effect on extramedullary relapses. The benefit of dexamethasone was partially counterbalanced by a significantly higher induction-related death rate (2.5% vs 0.9%, P = .00013), resulting in 5-year event-free survival rates of 83.9 ± 0.9% for dexamethasone and 80.8 ± 0.9% for prednisone (P = .024). No difference was seen in 5-year overall survival (OS) in the total cohort (dexamethasone, 90.3 ± 0.7%; prednisone, 90.5 ± 0.7%). Retrospective analyses of predefined subgroups revealed a significant survival benefit from dexamethasone only for patients with T-cell ALL and good response to the prednisone prephase (prednisone good-response [PGR]) (dexamethasone, 91.4 ± 2.4%; prednisone, 82.6 ± 3.2%; P = .036). In patients with precursor B-cell ALL and PGR, survival after relapse was found to be significantly worse if patients were previously assigned to the dexamethasone arm. We conclude that, for patients with PGR in the large subgroup of precursor B-cell ALL, dexamethasone especially reduced the incidence of better salvageable relapses, resulting in inferior survival after relapse. This explains the lack of benefit from dexamethasone in overall survival that we observed in the total cohort except in the subset of T-cell ALL patients with PGR. This trial was registered

    Prednisone and prednisolone bind in plasma to albumin and transcortin. In am attempt to determine whether prednisone side effects and/or type of disease correlated with prednisolone plasma protein binding, multiple plasma samples from 17 patients (three asthma, eight SLE, three RA, two PSS, one PAN) receiving long-term prednisone therapy were monitored during an interval between two prednisone doses. Prednisolone plasma protein binding was nonlinear and exhibited large intrapatient and interpatient variability. For the group, mean association constants of the prednisolone-albumin complex and the prednisolone-transcortin complex were 2.3 X 10(3) M-1 and 2.9 X 10(7) M-1, with coefficients of variation of 82% and 127%, respectively. SLE patients tended to have lower mean prednisolone association constants for albumin and transcortin than did other patients. The presence of corticosteroid side effects did not correlate with prednisolone plasma protein-binding parameters. The wide range of prednisolone free fraction noted in plasma from patients who achieved comparable total prednisolone plasma concentrations implies that administration of a uniform prednisone dose will not lead to a predictable clinical response.

    Objective:To evaluate the efficacy and factors of prednisone combined with cyclophosphamide (CTX) treatment of primary immunoglobulin A (IgA).Methods:Ninty six cases of IgA nephropathy patients were treated with prednisone combined CTX from January 2013 to December 2014. Renal function before and after treatment was measured and the effects of prednisone combined CTX in patients with IgA nephropathy were analyzed.Results:Thirty eight cases were cured in 96 cases of IgA nephropathy patients (39.58%), 42 cases were effective (43.75%), 16 cases were ineffective (16.67%), totally, and 80 were was ffective (83.33%). After treatment, blood urea nitrogen (BUN), serum creatinine (blood Scr), 24 h urine protein (24 h Uab) were lower than before treatment, and endogenous creatinine clearance (Ccr) were significantly higher than before treatment (P<0.05). After logistic regression, 24 h urine protein levels, Ccr before treatment, LEE kidney tissue classification, hypertension were risk factors of prednisone combined with CTX treatment on prognosis of patients with IgA nephropathy.Conclusions:Prednisone combined CTX is effective in the treatment of IgA nephropathy, but clinical and pathological features of patients should be considered in the choice of the program.

    Decay accelerating factor (DAF) expression at the muscle endplate is an important defence against complement-mediated damage in myasthenia gravis. Previously we implicated the c.-198C>G DAF polymorphism with the development of treatment-resistant myasthenia-associated ophthalmoplegia by showing that the C>G DAF polymorphism prevented lipopolysaccharide-induced upregulation of lymphoblast DAF. We postulated that drugs used in myasthenia gravis may increase the susceptibility of extraocular muscles to complement-mediated damage and studied their effects on endogenous DAF using patient-derived lymphoblasts as well as mouse myotubes. We show that prednisone repressed C>G DAF expression in lymphoblasts and increased their susceptibility to cytotoxicity. Methotrexate, but not azathioprine or cyclosporine, increased DAF in C>G lymphoblasts. In mouse myotubes expressing wild-type Daf, prednisone also repressed Daf expression. Although cyclosporine, azathioprine, and methotrexate increased muscle Daf levels when used alone, upon co-treatment with prednisone only azathioprine maintained myotube Daf levels close to basal. Therefore, prednisone negatively influences DAF expression in C>G lymphoblasts and in myotubes expressing wild-type Daf. We speculate that myasthenic individuals at risk of developing the ophthalmoplegic complication, such as those with C>G DAF, may have inadequate endogenous levels of complement regulatory protein protection in their extraocular muscle in response to prednisone, increasing their susceptibility to complement-mediated damage.

    Reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT) with alemtuzumab, fludarabine, and melphalan is an effective approach for patients with nonmalignant disorders. Mixed chimerism and graft-versus-host-disease (GVHD) remain limitations on success. We hypothesized that higher levels of alemtuzumab at day 0 would result in a low risk of acute GVHD, a higher risk of mixed chimerism, and delayed early lymphocyte recovery and that alemtuzumab level thresholds for increased risks of these outcomes would be definable. We collected data from 105 patients to examine the influence of peritransplant alemtuzumab levels on acute GVHD, mixed chimerism, and lymphocyte recovery. The cumulative incidences of initial grades I-IV, II-IV, and III-IV acute GVHD in patients with alemtuzumab levels ≤0.15 vs ≥0.16 μg/mL were 68% vs 18% (P alemtuzumab level ≤0.15 μg/mL was 21%, vs 42% with levels of 0.16 to 4.35 μg/mL, and 100% with levels >4.35 μg/mL (P = .003). Patients with alemtuzumab levels ≤0.15 or 0.16 to 0.56 μg/mL had higher lymphocyte counts at day +30 and higher T-cell counts at day +100 compared with patients with levels ≥0.57 μg/mL (all P alemtuzumab levels impact acute GVHD, mixed chimerism, and lymphocyte recovery following RIC HCT with alemtuzumab, fludarabine, and melphalan. Precision dosing trials are warranted. We recommend a day 0 therapeutic range of 0.2 to 0.4 μg/mL.

    Full Text Available BACKGROUND: Allogeneic hematopoietic stem cell transplantation with HLA-identical donors has been established for the treatment of acute myeloid leukemia patients for over 30 years with a cure rate of 50% to 60%. OBJECTIVES: To analyze the overall survival of patients and identify factors that influence the outcomes of this type of transplant in patients in 1st complete remission who received a busulfan and melphalan combination as conditioning regimen. METHODS: Twenty-five consecutive patients with acute myeloid leukemia were enrolled between 2003 and 2008. The median age was 34 years old (Range: 16 - 57 years. All patients received cyclosporine and methotrexate for prophylaxis against graft-versus-host disease. Median neutrophil engraftment time was 16 days (Range: 7 - 22 days and 17 days (Range: 7 - 46 days for platelets. Sinusoidal obstructive syndrome was observed in three patients, seven had grade II acute graft-versus-host disease and one extensive chronic graft-versus-host disease. RESULTS: The overall survival by the Kaplan-Meier method was 48% after 36 months with a plateau at 36 months after transplantation. Intensive consolidation with high-dose arabinoside resulted in an improved survival (p-value = 0.0001, as did grade II acute graft-versus-host disease (p-value = 0.0377 and mild chronic graft-versus-host disease (p-value < 0.0001. Thirteen patients died, five due to infection within 100 days of transplant, two due to hemorrhages, one to infection and graftversus-host disease and three relapses followed by renal failure (one and infection (two. The cause of death could not be determined for two patients. CONCLUSION: The busulfan and melphalan conditioning regimen is as good as other conditioning regimens providing an excellent survival rate.

    A newborn girl with hemorrhagic purpura, suspected neonatal sepsis, and pale and dry skin was lethargic with remarkable hepatosplenomegaly, convergent strabismus, severe anemia, and elevated alkaline phosphatase activity. Radiographs showed a generalized increase in bone density, small medullary cavities, sclerosis of the skull and vertebrae, transverse wavy stripes of sclerotic bone in the metaphyses, and bone-in-bone appearance in phalanges of hands and feet. On this basis, she was diagnosed with malignant infantile osteopetrosis. On the first day of life, the infant was given a blood transfusion and vitamin K (1 mg intravenously [iv]). Corticosteroid therapy was started with prednisone (2 mg/kg per day). She showed marked improvement of symptoms. On the 26th day and 42nd day of life, she received additional blood transfusions. On the 49th day, the patient was discharged and corticosteroid therapy was continued at a regimen of 5 mg/day. Subsequent blood sample analyses revealed normal values for age. At 1 year of life, a bone marrow sample showed normal white and red cell lineages. X-ray confirmed attenuation of the bone sclerosis; therefore, bone marrow transplantation (BMT) was not implemented. At the age of 1.5 years, prednisone therapy was discontinued gradually and withdrawn before the age of 2 years. Subsequent follow-up showed normalization of all radiological and hematologic parameters. At present, the patient is 3 years old and appears healthy with apparently complete regression of the disease.

    High P-glycoprotein-mediated multidrug resistance-1 (P-gp/MDR1) activity in lymphocytes from idiopathic thrombocytopenic purpura (ITP) patients may affect disease outcome. ITP treatment includes glucocorticoids that are substrates of P-gp; hence, P-gp functional activity and antigenic expression were assessed by flow cytometry in T and natural killer (NK) cells from ITP patients before and after prednisone therapy. Herein, patients' T and NK cells did not show increased MDR1 functional activity, whereas P-gp antigenic expression was significantly enhanced in both therapy-free and prednisone-treated patients. Prednisone treatment did not significantly modify the function and expression of MDR1 in T and NK cells of ITP patients.

    Chronic graft-versus-host disease (GVHD) induces significant morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Corticosteroids are standard initial therapy, despite limited efficacy and long-term toxicity. Based on our experience using bortezomib as effective acute GVHD prophylaxis, we hypothesized that proteasome-inhibition would complement the immunomodulatory effects of corticosteroids to improve outcomes in chronic GVHD (cGVHD). We undertook a single-arm phase II trial of bortezomib plus prednisone for initial therapy of cGVHD. Bortezomib was administered at 1.3 mg/m(2) i.v. on days 1, 8, 15, and 22 of each 35-day cycle for 3 cycles (15 weeks). Prednisone was dosed at .5 to 1 mg/kg/day, with a suggested taper after cycle 1. All 22 enrolled participants were evaluable for toxicity; 20 were evaluable for response. Bortezomib plus prednisone therapy was well tolerated, with 1 occurrence of grade 3 sensory peripheral neuropathy possibly related to bortezomib. The overall response rate at week 15 in evaluable participants was 80%, including 2 (10%) complete and 14 (70%) partial responses. The organ-specific complete response rate was 73% for skin, 53% for liver, 75% for gastrointestinal tract, and 33% for joint, muscle, or fascia involvement. The median prednisone dose decreased from 50 mg/day to 20 mg/day at week 15 (P prednisone for initial treatment of cGVHD is feasible and well tolerated. We observed a high response rate to combined bortezomib and prednisone therapy; however, in this single-arm study, we could not directly measure the impact of bortezomib. Proteasome inhibition may offer benefit in the treatment of cGVHD and should be further evaluated.

    We evaluated long-term outcomes of 60 patients with chronic lymphocytic leukemia treated with an initial therapy of lenalidomide. At a median follow-up of 4 years, time-to-treatment failure has not been reached and overall survival is 82%. Thirty-five (58%) patients had a response lasting >36 months (long-term responders [LTRs]). Best LTR responses consisted of 25 (71%) complete remissions and 10 (29%) partial remissions. In addition to clinical responses, an increase in IgA, IgG, and IgM levels of >50% from baseline was reported in 61%, 45%, and 42% of LTRs. Normalization in the percentage of CD4+ and CD8+ cells and T-cell numbers was observed in 48%, 71% and 99% of LTRs. Compared with other patients in the study, LTRs had lower baseline plasma levels of β-2-microglobulin, were more likely to have trisomy 12, and less likely to have deletion 17p.

    Full Text Available 49 patients aged 28 to 81 years old (median age of 55 years old with relapsed or refractory multiple myeloma (MM were enrolled in the study. The relapse was diagnosed in 25 (51 % patients, the refractory disease was determined in 24 (49 % patients (including primary refractory disease in 14 (28.6 % patients. The prior therapy for all patients included bortezomib-based treatment in combination with thalidomide and autologus stem cell transplantation (8.1 %. Lenalidomide had not been used in the previous therapeutic regimens. All patients were given the original treatment regimen, which included lenalidomide, bortezomib, and prednisolone (RVP. The therapy was made up of seven induction cycles with each one lasting for 48 days. Length of courses was 14 days. After seven cycles of RVP therapy were over, such results were achieved: complete response (CR in 1 (2 % patient; very good partial response (VGPR in 4 (8 % patients; partial response (PR in 26 (53 % patients; minimal response (MR in 2 (4 % patients; stable disease (SD in 8 (16.3 % patients, and progressive disease (PD in 8 (16.3 % patients. The objective response rate, including CR+VGPR+PR, was obtained in 31 (63.1 % patients. The objective response rate, including MR, was seen in 33 (67.1 % patients. Hematological and non-hematological toxicities were moderate. Taking into account the above, the RVP therapeutic regimen has demonstrated its efficacy as a second-line therapy for MM, and its clinical use can solve the problem of relapsed/refractory to bortezomib-based regimens MM management.

    Bortezomib and lenalidomide are increasingly used in patients with AL amyloidosis, but long term data on their use as primary therapy in AL amyloidosis are lacking while early mortality remains significant. Thus, we analyzed the long term outcomes of 85 consecutive unselected patients, which received primary therapy with bortezomib or lenalidomide and we prospectively evaluated a risk adapted strategy based on bortezomib/dexamethasone to reduce early mortality. Twenty-six patients received full-dose bortezomib/dexamethasone, 36 patients lenalidomide with oral cyclophosphamide and low-dose dexamethasone and 23 patients received bortezomib/dexamethasone at a dose and schedule adjusted to the risk of early death. On intent to treat, 67% of patients achieved a hematologic response (24% hemCRs) and 34% an organ response; both were more frequent with bortezomib. An early death occurred in 20%: in 36% of those treated with full-dose bortezomib/dexamethasone, in 22% of lenalidomide-treated patients but only in 4.5% of patients treated with risk-adapted bortezomib/dexamethasone. Activity of full vs. adjusted dose bortezomib/dexamethasone was similar; twice weekly vs. weekly administration of bortezomib also had similar activity. After a median follow up of 57 months, median survival is 47 months and is similar for patients treated with bortezomib vs. lenalidomide-based regimens. However, risk adjusted-bortezomib/dexamethasone was associated with improved 1-year survival vs. full-dose bortezomib/dexamethasone or lenalidomide-based therapy (81% vs. 56% vs. 53%, respectively). In conclusion, risk-adapted bortezomib/dexamethasone may reduce early mortality and preserve activity while long term follow up indicates that remissions obtained with lenalidomide or bortezomib may be durable, even without consolidation with alkylators. © 2015 Wiley Periodicals, Inc.

    Full Text Available This study aimed to assess the efficacy and safety of combination treatment with lenalidomide and cetuximab in KRAS-mutant metastatic colorectal cancer patients. This was a phase II multicenter, open-label trial comprising a safety lead-in phase (phase IIa to determine the maximum tolerated dose, and a randomized proof of concept phase (phase IIb to determine the response rate of lenalidomide plus cetuximab combination therapy. Phase IIa treatment comprised oral lenalidomide (starting dose 25 mg/day and intravenous cetuximab (400 mg/m(2 followed by weekly 250 mg/m(2 in 28-day cycles. In phase IIb patients were randomized to either the phase IIa treatment schedule of lenalidomide plus cetuximab combination therapy or lenalidomide 25 mg/day monotherapy. Eight patients were enrolled into phase IIa. One patient developed a dose-limiting toxicity and the maximum tolerated dose of lenalidomide was determined at 25 mg/day. Forty-three patients were enrolled into phase IIb proof of concept. Best response was stable disease in 9 patients and study enrollment was terminated prematurely due to lack of efficacy in both treatment arms and failure to achieve the planned response objective. The majority of adverse events were grade 1 and 2. In both phases, the adverse events most commonly attributed to any study drugs were fatigue, rash and other skin disorders, diarrhea, nausea, and stomatitis. Thirty-nine deaths occurred; none was related to study drug. The combination of lenalidomide and cetuximab appeared to be well tolerated but did not have clinically meaningful activity in KRAS-mutant metastatic colorectal cancer patients.Clinicaltrials.gov NCT01032291.

    Patients with multiple myeloma (MM) and severe renal impairment (SRI) have shorter survival than MM patients without renal failure. Although lenalidomide is a highly active drug, this immunomodulatory agent is frequently neglected in this context due to its predominant renal clearance and, consequently, an increased risk of toxicity. This risk might be overcome with the proper lenalidomide dose adjustment to renal function. This study evaluates the outcomes of 23 relapsed MM patients with SRI (baseline creatinine clearance (CrCl) lenalidomide-dexamethasone (LenDex), including 56 % (13 patients) under hemodialysis. The median CrCl at start of LenDex was 19 mL/min; an overall response rate (partial response or better) of 56 % was obtained, with a median follow-up from start of LenDex of 52 months (8-79). The median time until maximal response was 4 months, and in 58 % (7/12), the response was longer than 2 years. Nine percent had renal improvement, but all the 13 patients on hemodialysis remained under treatment. LenDex was interrupted in three cases because of adverse events (infections and cutaneous events); 78 % of the patients were on thromboprophylaxis with aspirin. It is important to notice that, after initial dose adjustment of therapy, there should be a continuous process of dose adjustment, taking into account variations in renal function. Furthermore, lenalidomide dose adjustment should be made according to the individual tolerance, even with stable renal function. LenDex dose adjustment, according to these principles, does not negatively impact response and improves treatment tolerance. It has a clear potential to treat this group of patients and to induce long duration of responses [event-free survival (EFS) 20.5 m and overall survival (OS) 42.6 m].

    Patients with high risk myelodysplastic syndromes (MDS) and acute myelogenous leukemia (AML) are commonly older with multiple co-morbidities, rendering them unsuitable for intensive induction chemotherapy or transplantation. We report preliminary cellular immune profiling of four cases receiving sequential clofarabine and lenalidomide for high risk MDS and AML in a phase I study. Our results highlight the potential of immune profiling for monitoring immune-modifying agents in high risk MDS and AML.

    Three groups of children with acute lymphoblastic leukemia (ALL) were treated with intermittent cyclophosphamide, vincristine, cytosine arabinoside, and prednisone (COAP). Group A (no prior relapse) and Group B (prior single-agent relapse) received COAP after 12 months on another chemotherapy regimen. Children in Group C (prior relapse on multiagent regimens) received COAP following A-COAP (asparaginase plus COAP) reinduction. Median disease-free survival after beginning COAP was not reached for Group A, but was only 7 months for Groups B and C. As of November 1976, there were 8 of 15 Group A patients, 1 of 12 Group B patients, and 1 of 28 Group C patients who had remained disease-free from 38 to 60 (median 54.5) months and were off chemotherapy. COAP has activity in childhood ALL. However, effectiveness is markedly diminished in patients with prior bone marrow relapse.

    Atrial fibrillation (AF) affects 2.3 million people in the United States and is currently the most common cardiac arrhythmia. Its overall prevalence is only increasing as the population ages. The classical risk factors for developing AF include hypertension, valvular disease, ischemic cardiomyopathy, and thyroid disease. In some patients with AF, an underlying cardiovascular pathology is not identified and the etiology remains unknown. Treatment modalities for AF typically include rate control medications, antiarrhythmics and radio frequency ablation (RFA), each of which is accompanied by its own risk of complications. We report a case of symptomatic AF that was refractory to multiple antiarrhythmics and an RFA procedure which resolved with prednisone. In this case, AF was associated with cardiac sarcoidosis, a disorder that is thought to be due to granulomatous involvement of the myocardium and increased systemic inflammation.

    Full Text Available A 35-year old male patient developed elevated transaminases about an year after cadaveric donor renal transplantation maintained on triple immunosuppression therapy. Azathioprine was discontinued and the liver enzymes normalized. Three years later, he showed evidence of cyclosporin (CyA nephrotoxicity as well as sclerosing cholangitis. The dose of CyA was therefore reduced. This was followed shortly by deterioration of his renal function and mycophenolate mofetil (MMF (3 gm daily was therefore introduced. He developed intractable diarrhea, which improved on reducing the dose of MMF to 2 gm per day. Eventually, the patient seemed to stabilize on low dose CyA and prednisone (Pred along with 2 gm of MMF. Four months later, the patient discontinued CyA on his own but continued with MMF and Pred. Over the following two years, his renal functions have remained stable with serum creatinine of around 120 µmol/L, despite the low immunosuppression being administered.

    Repeated plasm exchanges were performed in a 44-year-old man with Goodpasture syndrome, also treated with cyclophosphamide and prednisone. Improvement was observed within 3 weeks of starting the protocol, and by the 76th week, endogenous creatinine clearance had increased from 30 to 56 ml/min/1.73 M2 and serum albumin from 2.7 to 3.7 g/dl. Prior treatment with immunosuppressive drugs had not significantly influenced circulating antibody levels. But sustained suppression of antibody was achieved after the plasma exchanges were begun, suggesting that physical removal of circulating antibody combined with antiproliferative drug treatment may be a useful way to control undesirable humoral immune responses.

    Influence of body condition (over-conditioned vs. normal-conditioned) on plasma glucocorticoid concentrations after single dose oral prednisolone or prednisone in 11 cats (5 normal-conditioned and 6-over-conditioned) was investigated using a two-drug crossover trial (3-week washout interval). Body condition was determined using criterion-referenced bioelectrical impedance together with plasma drug concentrations (prednisolone [active drug] and prednisone [pro-drug]) measured by HPLC. Although interconversion of each drug to the other was confirmed, a single 2mg/kg body weight oral dose of prednisolone produced significantly higher plasma prednisolone concentration (∼4-fold higher AUC) compared to prednisone. Significantly higher plasma drug concentrations in over-conditioned cats (∼2-fold) compared to normal-conditioned cats might explain their perceived increased risk for glucocorticoid associated side effects (hepatic lipidosis, diabetes mellitus). Findings suggest low comparative bioavailability of oral prednisone compared to prednisolone in cats and consideration of lean body mass or ideal body weight for dosing practices.

    Full Text Available Multiple myeloma is the second most common hematologic malignancy. It accounts for 20,580 new cancer cases in the USA in 2009, including 11,680 cases in men, 8,900 cases in women, and 10,580 deaths overall. Although the disease remains still incurable, outcomes have improved substantially over recent years thanks to the use of high-dose therapy and the availability of novel agents, such as the immunomodulatory drugs thalidomide and lenalidomide, and the proteasome inhibitor bortezomib. Various trials have shown the advantages linked to the use of novel agents in the transplant and not-transplant settings. In particular, this paper will present an overview of the results achieved with lenalidomide-containing combinations in patients eligible for high-dose therapies, namely, young patients. The advantages obtained should always be outweighed with the toxicity profile associated with the regimen used. Therefore, here, we will also provide a description of the main adverse events associated with lenalidomide and its combination.

    Although lenalidomide maintenance therapy has demonstrated improved outcomes after autologous hematopoietic stem cell transplantation (auto-HCT) for patients with multiple myeloma (MM), the impact of the duration of this therapy is not clearly known. This study retrospectively analyzed all MM patients who were placed on maintenance lenalidomide after auto-HCT between January 2007 and December 2013. Progression-free survival (PFS) and overall survival (OS) were analyzed in multivariate Cox proportional hazards regression models that included the duration of maintenance as a time-dependent covariate. Of the 464 patients identified, 46% initiated therapy early (maintenance for >2 years versus those on maintenance for ≤2 years. For those on maintenance for >3 versus those on maintenance for ≤3 years, this trend continued with improvements seen in PFS (HR, 0.02; 95% CI, 0.00-0.44; P = .012) and OS (HR, 0.05; 95% CI, 0.00-0.83; P = .037). The incidence of second primary malignancies (SPMs) in the entire cohort was 3%. No differences were seen in survival between early and late initiators of maintenance lenalidomide. A longer duration of maintenance therapy was associated with longer survival. The incidence of SPMs was low, and they were not associated with the duration of maintenance. The timing of the initiation of maintenance had no effect on survival. Cancer 2016;122:3831-3837. © 2016 American Cancer Society. © 2016 American Cancer Society.

    Objective: To observe the clinical therapeutic effect of docetaxel, prednisone and bevacizunab in the treatment of hormone refractory prostate cancer. Methods:A total of 100 patients with hormone refractory prostate cancer were selected and randomly divided into 2 groups: chemotherapy group and combined group, 50 cases for each. Patients in chemotherapy group were given oral administration of hexadecadrol, 8 mg/d, intravenous drip of docetaxel, 40 mg/m2, orally taking of prednisone, 5 mg/d. Patients in combined group was added with bevacizumab, 5 mg/kg (which was diluted to 100 mL of chloride sodium injection) based on regimen of chemotherapy group. All patients were followed up every month after the end of treatment for recording reoccurrence, metastasis and deaths. Additionally, serum prostate-speciifc antigen (PSA), free prostate-speciifc antigen (fPSA)/total prostate-speciifc antigen (tPSA) before and after chemotherapy, prostate volume, maximum flow rate, the quality of life (QOL) were measured and evaluated. The progression-free survival (PFS) and the overall survival (OS) were analyzed by Kaplan-Meier method. Results: After treatment, the level of PSA in combined group was lower than that in chemotherapy group (P0.05). The median PFS and OS in combined group were 13 months and 20 months, respectively, higher than those in chemotherapy group (10 months and 17 months) (P0.05). Conclusion: Docetaxel combined with Bevacizunab can prolong the survival time of patients with hormone refractory prostate cancer, but its therapeutic effect still needs to be further veriifed. Additionally, with the in-depth of studies on hormone refractory prostate cancer in translational medicine, immunotherapy, targeted therapy, individualized treatment and multidrug therapy will surely become the research hotspot for hormone refractory prostate cancer.

    The present study was aimed at investigating whether low dose oral prednisone combined with escin could inhibit the progression of adjuvant-induced arthritis (AIA) in rats. Adjuvant arthritis was induced in SD rats began day 1 for 28 days. Prednisone at doses of 2, 10 mg/kg/day alone or escin at doses of 5, 10 mg/kg/day alone, or prednisone at dose of 2 mg/kg/day with escin at doses of 5 or 10 mg/kg/day were given to different groups of rats intragastrically from day 13 to 28 respectively. Paw swelling, arthritic index, histological and radiographic changes were assessed to evaluate the anti-arthritic effect. Weight growth, spleen and thymus indexes were also calculated. Serum samples were collected for estimation of pro-inflammatory cytokines. Rats developed erosive arthritis of the hind paw when immunized with adjuvant. Prednisone 2 mg/kg combined with escin 5 or 10 mg/kg significantly inhibited the paw swelling. Histopathological and radiographic analysis showed a marked decrease of synovial inflammatory infiltration, synovial hyperplasia and bone erosion by combination therapy, which also markedly suppressed the expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6). No significant changes were found in monotherapy group except prednisone 10 mg/kg group. Furthermore, combined treatment rescued some of GCs' adverse effects evidenced by increase in body weight and decrease in index of spleen compared with untreated AIA rats. In conclusion, the combination therapy possessed synergistic anti-arthritic efficacy and reduced adverse effect, which may play a role in the management of human RA.

    Bendamustine + rituximab (BR) has demonstrated high response rates in relapsed/refractory (R/R) chronic lymphocytic leukaemia (CLL) and small lymphocytic lymphoma (SLL). However, progression-free survival (PFS) after BR is lenalidomide after BR induction could improve PFS in R/R CLL/SLL. Thirty-four patients with R/R CLL/SLL who had received 1-5 prior chemotherapy regimens were treated with 6 cycles of BR induction. Patients achieving at least a minor response received twelve 28-d cycles of lenalidomide 5-10 mg/d. The primary endpoint was PFS. The median age was 67 years, with a median of 2 prior therapies. Eleven patients had confirmed presence of 17p and/or 11q deletions. Twenty-five (74%) completed 6 cycles of induction BR (response rate 56%). Nineteen (56%) patients received maintenance lenalidomide; only 6 patients completed the intended 12 cycles, highlighting the limited feasibility of lenalidomide in this setting, primarily due to haematological and infectious toxicities. The observed median PFS of 18·3 months is not significantly different from that of BR induction in R/R CLL/SLL without maintenance therapy (15·2 months). It is possible that lenalidomide maintenance may be more feasible and effective in the front-line setting, which is being tested in an ongoing trial (NCT01754857).

    Clinical trial results indicate that lenalidomide, an immunomodulatory drug, is a promising treatment in relapsed/refractory non-Hodgkin lymphoma (NHL). This retrospective multicenter study was conducted in patients with relapsed/refractory NHL treated with lenalidomide monotherapy through a Named Patient Program in Italy. Principal endpoints were overall response rate (ORR), safety and overall survival (OS). The ORR in 64 evaluable patients was 42.2% and was similar among patients receiving 10, 15 or 25 mg/day lenalidomide. Response rates in patients with mantle cell, diffuse large B-cell and follicular lymphoma were 45.5%, 42.1% and 20%, respectively. Among patients who responded to most recent prior therapy, ORR was 50.0% versus 36.8% in patients with refractory NHL. Mean duration of response in patients receiving any lenalidomide dose was 10.5 months; 1-year progression-free survival and OS were 50.3% and 82.6%, respectively. These findings suggest that lenalidomide is effective and safe for heavily pretreated patients with NHL in the clinical setting.

    Treatment advances for multiple myeloma (MM) that have prolonged survival emphasise the importance of measuring patients' health-related quality of life (HRQoL) in clinical studies. HRQoL/functioning and symptoms of patients with relapsed/refractory MM (RRMM) receiving second- or third-line lenalidomide or bortezomib treatment were measured in a prospective European multicentre, observational study at different time points. At baseline, patients in the lenalidomide cohort were frailer than in the bortezomib cohort with more rapid disease progression at study entry (more patients with Eastern Cooperative Oncology Group performance status >2, shorter time from diagnosis, more chronic heart failure, higher serum creatinine levels, more patients with dialysis required). About 40% of the patients receiving lenalidomide discontinued the study in Life Core domains of Diarrhoea and Global Health Status/QoL had worsened in the lenalidomide and bortezomib cohorts, respectively. A clinically meaningful deterioration in HRQoL was more often observed for patients who discontinued the study prior to 6 months in the bortezomib cohort than in the lenalidomide cohort.

    Sporadic late-onset nemaline myopathy (SLONM) is a rare, late-onset myopathy that progresses subacutely. If associated with a monoclonal gammopathy of unknown significance (MGUS), the outcome is unfavorable: the majority of these patients die within 1 to 5 years of respiratory failure. This study aims to qualitatively assess the long-term treatment effect of high-dose melphalan (HDM) followed by autologous stem cell transplantation (SCT) in a series of 8 patients with SLONM-MGUS. We performed a retrospective case series study (n = 8) on the long-term (1-8 years) treatment effect of HDM followed by autologous SCT (HDM-SCT) on survival, muscle strength, and functional capacities. Seven patients showed a lasting moderate-good clinical response, 2 of them after the second HDM-SCT. All of them had a complete, a very good partial, or a partial hematologic response. One patient showed no clinical or hematologic response and died. This case series shows the positive effect of HDM-SCT in this rare disorder. Factors that may portend an unfavorable outcome are a long disease course before the hematologic treatment and a poor hematologic response. Age at onset, level and type of M protein (κ vs λ), and severity of muscle weakness were not associated with a specific outcome. This study provides Class IV evidence that for patients with SLONM-MGUS, HDM-SCT increases the probability of survival and functional improvement. © 2014 American Academy of Neurology.

    5-(3,3-Dimethyl-1-triazeno)imidazole-4-carboxamide (NSC-45388), melphalan, and hydroxyurea were evaluated in a randomized clinical trial in which 35 patients with disseminated malignant melanoma were treated. Therapeutic results were not impressive. Objective remissions were noted in two of the 23 patients who received NSC-45388, none of the 21 who received melphalan, and none of the 24 who received hydroxyurea. Toxicity was significant but tolerable: gastrointestinal toxicity was noted in 23 of the 23 patients who received NSC-45388, 15 of the 21 who received melphalan, and 16 of the 24 who received hydroxyurea. Hematologic toxicity resulted in leukocyte counts less than 3000 cells/mm3 in seven of the 23 patients who received NSC-45388, six of the 21 who received melphalan, and 18 of the 24 who received hydroxyurea. Platelet depression, with cell counts less than 100,000 cells/mm3, was noted in five of the 23 patients who received NSC-45388, three of the 21 who received melphalan, and six of the 24 who received hydroxyurea.

    Duchenne muscular dystrophy (DMD) is a fatal neuromuscular disease for which there is no cure and limited treatment options. Prednisone is currently the first line treatment option for DMD and studies have demonstrated that it improves muscle strength. Although prednisone has been used for the treatment of DMD for decades, the mechanism of action of this drug remains unclear. Recent studies have shown that the α7β1 integrin is a major modifier of disease progression in mouse models of DMD and is therefore a target for drug-based therapies. In this study we examined whether prednisone increased α7β1 integrin levels in mdx mouse and GRMD dog models and myogenic cells from humans with DMD. Our results show that prednisone promotes an increase in α7 integrin protein in cultured myogenic cells and in the muscle of mdx and GRMD animal models of DMD. The prednisone-mediated increase in α7 integrin was associated with increased laminin-α2 in prednisone-treated dystrophin-deficient muscle. Together, our results suggest that prednisone acts in part through increased merosin in the muscle basal lamina and through sarcolemmal stabilization of α7β1 integrin in dystrophin-deficient muscle. These results indicate that therapies that target an increase in muscle α7β1 integrin, its signaling pathways and/or laminin could be therapeutic in DMD.

    Oral prednisone is considered the standard first-line therapy of adult immune thrombocytopenia, but its long-term efficacy is limited. We performed a prospective, randomized, multicenter trial comparing daily prednisone (1-2 mg/kg/day for 2-4 weeks with subsequent dose reduction) with six 3-week cycles of pulsed dexamethasone (0.6 mg/kg/day, days 1-4). The primary endpoint was remission duration. Of 26 patients enrolled, 22 were evaluable for response. Nine were treated with prednisone and 13 with dexamethasone. The median follow-up was 46 months. The initial response rate (PLT ≥50 × 109/l) was 100% in both groups. Long-term remissions were significantly more frequent with pulsed dexamethasone than with daily prednisone (12 months posttreatment: 77 vs. 22%; p = 0.027). The side effects were similar, but patients on dexamethasone suffered significantly more often from insomnia, while patients on prednisone tended to have more infectious complications. Although the cumulative cortisol equivalent dose was comparable during the first 4 weeks of therapy, it was significantly higher in the dexamethasone arm than in the prednisone arm during the ensuing treatment period. We conclude that repeated cycles of pulsed dexamethasone are a good alternative to daily prednisone as a first-line treatment of immune thrombocytopenia. The duration and intensity of glucocorticoid therapy are important determinants of treatment outcome.

    Full Text Available Objective: To observe the clinical therapeutic effect of docetaxel, prednisone and bevacizunab in the treatment of hormone refractory prostate cancer. Methods: A total of 100 patients with hormone refractory prostate cancer were selected and randomly divided into 2 groups: chemotherapy group and combined group, 50 cases, respectively. Patients in chemotherapy group were given oral administration of hexadecadrol, 8 mg/d, intravenous drip of docetaxel, 40 mg/m2, orally taking of prednisone, 5 mg/d. Patients in combined group was added with bevacizumab, 5 mg/kg (which was diluted to 100 mL of chloride sodium injection based on regimen of chemotherapy group. All patients were followed up every month after the end of treatment for recording reoccurrence, metastasis and deaths. Additionally, serum prostate-specific antigen (PSA, free prostate-specific antigen (fPSA/total prostate-specific antigen (tPSA before and after chemotherapy, prostate volume, maximum flow rate, the quality of life (QOL were measured and evaluated. The progression-free survival (PFS and the overall survival (OS were analyzed by Kaplan-Meier method. Results: After treatment, the level of PSA in combined group was lower than that in chemotherapy group (P<0.01 while fPSA/tPSA in combined group was higher than that in chemotherapy group after treatment (P<0.01. The prostate volume of two groups decreased, the maximum flow rate and QOL score of two groups increased, but with no difference between two groups (P>0.05. The median PFS and OS in combined group were 13 months and 20 months, respectively, higher than those in chemotherapy group (10 months and 17 months (P<0.01. The occurrence rate of adverse reactions was 66.00% in combined group and 56.00% in chemotherapy group, but with no significance between them (P>0.05. Conclusion: Docetaxel combined with Bevacizunab can prolong the survival time of patients with hormone refractory prostate cancer, but its therapeutic effect still

    Full Text Available Background: Lenalidomide is an effective treatment for patients with lower risk myelodysplastic syndrome (MDS del5q. It reduces disease-related transfusion requirements, inhibits the malignant clone and causes a delay in tumor growth. There are also benefits in terms of quality of life and use of other health care resources. Objective: To perform an economic evaluation of lenalidomide for transfusion-dependent patients with Low/ Intermediate-1-risk MDS del 5q from the perspective of the public health care sector in Mexico. Material and methods: We developed a cost-effectiveness analysis using a Markov model of 5 stages: MDS transfusion- dependence, MDS transfusion-independence, complications from transfusion, acute myeloid leukemia, and death. The analyzed period was 5 years. Discount rate of 5% after year 1 was applied. Efficacy was elicited from a phase III clinical trial, MDS-004, which shows lenalidomide benefit in patients achieving transfusion-independence. There were also benefits with lenalidomide related to extended overall survival and decreased risk of acute myeloid leukemia. Unitary cost are from public price list of IMSS, and resources use was calculated from a Delphi panel methodology with clinical hematologists. A multivariate sensitivity analysis using a Monte Carlo technique was performed. Results: Over a 5-year period, each patient on lenalidomide avoided 487 days of transfusion, on average. The incremental cost per life-year without transfusion dependence is USD$14,072 (Exchange Rate = 1USD = 17.55 MXN. According to the sensitivity analysis the model is robust. If all expected patients are treated, their cost would be ~USD$19.7 million, which represents 0.18% of the total budget in the public health sector. Conclusions: Lenalidomide provides important clinical benefits in the treatment of patients with lower risk myelodysplastic syndromes with del5q, with a limited economic impact and with a cost per life living without blood

In clinical trials, rash was common, although severe rash was infrequent. To examine rash in patients with MDS treated with lenalidomide in the real world, the Celgene Global Drug Safety database was analyzed and compared with clinical trials.Materials and methods: Adverse event reports in the post-marketing setting and in the MDS-003/004 clinical trials were analyzed by action taken with lenalidomide, seriousness/grade, time to onset, and treatment duration.Results: Globally, 16,942 reports representing 36,793 adverse events from the post-marketing setting were submitted to the Global Drug Safety database between December 27, 2005 and June 13, 2013. Most rash adverse events were non-serious (Global Drug Safety database, 91% or grade 1/2 (MDS-003/004 trials, 87%–93%. Unexpectedly, rash, occurring at a median of 9 days after treatment initiation, was the leading cause of permanent discontinuation of lenalidomide. Seventy-two percent of non-serious rash adverse events led to early permanent discontinuation within two cycles, while in the MDS-003/004 pivotal clinical trials, only 2%–3% of rash adverse events led to permanent discontinuation.Conclusion: Non-serious rash was the most common reason for permanent discontinuation of lenalidomide in real-world settings. Managing lenalidomide-related rash using published recommendations might improve treatment duration and optimize patient outcomes. Keywords: adverse events, safety, post-marketing setting

    Downregulation of cereblon (CRBN) gene expression is associated with resistance to the immunomodulatory drug lenalidomide and poor survival outcomes in multiple myeloma (MM) patients. However, the importance of CRBN gene expression in patients with myelodysplastic syndrome (MDS) and its impact on lenalidomide therapy are not clear. In this study, we evaluate cereblon expression in mononuclear cells isolated from bone marrow [23 lower risk MDS patients with isolated 5q deletion (5q-), 37 lower risk MDS patients with chromosome 5 without the deletion of long arms (non-5q-), and 24 healthy controls] and from peripheral blood (38 patients with 5q-, 52 non-5q- patients and 25 healthy controls) to gain insight into, firstly, the role of cereblon in lower risk MDS patients with or without 5q deletion and, secondly, into the mechanisms of lenalidomide action. Patients with 5q- lower risk MDS have the highest levels of CRBN mRNA in comparison with both lower risk MDS without the deletion of long arms of chromosome 5 and healthy controls. CRBN gene expression was measured using the quantitative TaqMan real-time PCR. High levels of CRBN mRNA were detected in all lenalidomide responders during the course of therapy. A significant decrease of the CRBN mRNA level during lenalidomide treatment is associated with loss of response to treatment and disease progression. These results suggest that, similar to the treatment of MM, high levels of full-length CRBN mRNA in lower risk 5q- patients are necessary for the efficacy of lenalidomide.

  12. Molecular mechanism of action of immune-modulatory drugs thalidomide, lenalidomide and pomalidomide in multiple myeloma.

    Although several mechanisms have been proposed to explain the activity of thalidomide, lenalidomide and pomalidomide in multiple myeloma (MM), including demonstrable anti-angiogenic, anti-proliferative and immunomodulatory effects, the precise cellular targets and molecular mechanisms have only recently become clear. A landmark study recently identified cereblon (CRBN) as a primary target of thalidomide teratogenicity. Subsequently it was demonstrated that CRBN is also required for the anti-myeloma activity of thalidomide and related drugs, the so-called immune-modulatory drugs (IMiDs). Low CRBN expression was found to correlate with drug resistance in MM cell lines and primary MM cells. One of the downstream targets of CRBN identified is interferon regulatory factor 4 (IRF4), which is critical for myeloma cell survival and is down-regulated by IMiD treatment. CRBN is also implicated in several effects of IMiDs, such as down-regulation of tumor necrosis factor-α (TNF-α) and T cell immunomodulatory activity, demonstrating that the pleotropic actions of the IMiDs are initiated by binding to CRBN. Future dissection of CRBN downstream signaling will help to delineate the underlying mechanisms for IMiD action and eventually lead to development of new drugs with more specific anti-myeloma activities. It may also provide a biomarker to predict IMiD response and resistance.

    The introduction of immunomodulatory drugs such as lenalidomide combined with dexamethasone (Len/Dex) has improved the outcome of patients with relapsed/refractory multiple myeloma (RRMM). Few data are currently available which investigate whether paraprotein relapse represents an indication for starting a new treatment. The aim of our retrospective, single-center study was to analyze the impact of disease status (relapsed/refractory) and type of relapse (clinical/paraprotein) on response rate and time-to-next-treatment (TNT). We included 74 patients (median age 70 years) with RRMM treated with Len/Dex until progression or unacceptable toxicity from 2008 to 2012. Age and disease status were not factors affecting overall response rate (ORR) and median TNT, but TNT was significantly longer in patients with asymptomatic compared to clinical relapse (34 vs. 19 months, p<0.008). In conclusion, Len/Dex represents an effective treatment with satisfactory ORR and outcomes in RRMM, especially for patients starting therapy in asymptomatic relapse.

    Immunomodulatory drugs (IMiDs) may favor autoimmune disease (AD) occurrence. We conducted a retrospective study to evaluate AD occurrence among IMiD-treated patients with myeloma. Patients were grouped into three classes depending on the type of IMiD engaged. The first group included patients treated with thalidomide (Thal) (n = 474), the second group with lenalidomide (Len) (n = 140) and patients in the third group were first treated with Thal followed by Len (Thal-Len) (n = 94). Absolute risk of AD was 0.4% for patients treated with Thal, 4.3% for Len and 1.1% for Thal-Len. ADs manifested prevalently as autoimmune cytopenias (55%), although we observed one vasculitis, one optic neuritis, one Graves' disease and one polymyositis. ADs occurred preferentially in the first months of IMiD treatment. A previous autologous transplant was shown to be a significant risk factor. All ADs were managed with IMiD discontinuation and steroids, resolving in a few weeks, except for Graves' disease and polymyositis.

    The combination of lenalidomide, bortezomib and dexamethasone (RVD) has shown excellent efficacy in patients with relapsed or refractory multiple myeloma (RRMM). The aim of our study was to assess the efficacy and toxicity profile of RVD for patients with advanced RRMM. We retrospectively reviewed the records of all patients with RRMM treated with RVD between March 2009 and December 2011. Thirty patients received ≥ 1 full cycle of RVD. Primary endpoints were overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). After a median of 5 cycles (1-16), a very good partial response (VGPR) was seen in 10%, partial response (PR) in 36.7% and stable disease (SD) in 13.3% (ORR of 46.7%). Disease progression occurred in 21 patients at a median of 3 months (range 1.41-4.59). Eight patients (26%) experienced grade 3/4 adverse events, including anemia, neutropenia, muscle weakness and pneumonia. No patient experienced worsening peripheral neuropathy. Although RVD has been previously shown to be effective in RRMM, the ORR and PFS we observed were affected by very advanced disease status and heavy prior exposure to novel agents. Nevertheless, six of these patients with RRMM experienced a benefit of ≥ 6 months, suggesting synergism of this immunomodulatory derivative/proteasome inhibitor combination and/or re-establishment of drug sensitivity by an emergent myeloma clone.

    Full Text Available Hormone-resistant prostate cancer (HRPC occurs when prostate cancer is no longer responsive to hormone therapy. Treatment options are limited, and there is a clear necessity for therapies that improve outcome. Preclinical and clinical evidence supports the role of the immunomodulatory agent lenalidomide in HRPC. In this paper, we report that lenalidomide showed antitumoral activity in a patient with HRPC and bone metastases pre-treated with chemotherapy, decreased the PSA level and improved the patient’s health status for the first 5 months. It is important to emphasize that it was not associated with hematologic toxicity.

    The addition of cytotoxic drugs to high-dose melphalan as a preparative regimen for autologous stem cell transplantation in multiple myeloma has not resulted in superior activity. Although novel agents have significantly improved outcome in multiple myeloma, their role in preparative regimens remains largely unknown. We have evaluated the toxicity and efficacy of combining bortezomib, thalidomide, and dexamethasone with high-dose melphalan. An institutional review board-approved retrospective analysis was performed on 100 consecutive patients receiving 153 transplants; 53 had tandem transplants; 64 patients received early transplants; and 36 had salvage transplantation. Endpoints were treatment-related toxicity and mortality, and quality of response post-transplantation with assessment of stringent complete remission (sCR) and minimal residual disease (MRD) status. Median age was 61 years, and median follow-up was 16.2 months. At 6 months, sCR was attained in 56% of patients and CR in 20%. An MRD status, assessed by sensitive (10(-4)) multiparameter flow cytometry, was achieved in 85%. The 100-day mortality rate was 2.6% (4/153); 1.8% for early transplants and 4.5% for salvage transplants. Grade 3-5 non-hematologic toxicities were mainly related to metabolism/nutrition; gastrointestinal and infectious problems. Median time to absolute neutrophil count of >500/µL was 12 days for both early and salvage transplantations. No significant differences in quality of response were observed between early and salvage transplantation or between single and tandem autologous stem cell transplantation. Since both sCR and MRD are excellent early surrogate markers for progression-free and overall survival, this regimen will likely be superior to melphalan alone, but it needs to be formally assessed in a randomized study.

    Stem cell transplantation (SCT), an effective therapy for amyloid light chain (AL) amyloidosis patients, is associated with low treatment-related mortality (TRM) with appropriate patient selection and risk-adapted dosing of melphalan (RA-SCT). Consolidation after SCT increases hematologic complete response (CR) rates and may improve overall survival (OS) for patients with Melphalan was administered at 100 (14%), 140 (52%) and 200 (34%) mg/m2. The TRM rate at 100 days was 5%. RA-SCT resulted in CR in 24% (3 months) and 48% (12 months) of patients. The CR rate was particularly high (62%) in patients offered bortezomib consolidation. With a median follow-up among survivors of 7.7 years, median event-free survival (EFS) with RA-SCT was 4.04 years (95% confidence interval (CI): 3.41–5.01 years); median OS was 10.4 years (95% CI: 7.3–not achieved). Patients with CR at 12 months after SCT had significantly longer EFS (P=0.01) and OS (P=0.04). In a multivariate analysis, melphalan dose had no impact on EFS (P=0.26) or OS (P=0.11). For selected patients, RA-SCT was safe and was associated with extended long-term survival. With the availability of novel agents for consolidation, RA-SCT remains a very effective and important backbone treatment for AL amyloidosis. PMID:27560108

    This study aimed at the identification of histone deacetylase (HDAC) isoforms relevant for childhood acute lymphoblastic leukemia (ALL). Expression of HDAC1-11 was determined in 93 primary ALL and eight healthy donor samples. HDAC1, HDAC2 and HDAC8 showed significantly higher expressions in ALL samples. Correlation analysis of HDAC expression with clinicopathological parameters revealed that high HDAC1, HDAC2, HDAC4 and HDAC11 levels were significantly associated with unfavorable prognostic factors. Particularly, high HDAC4 expression was associated with high initial leukocyte count, T cell ALL and prednisone poor-response. siRNA-mediated inhibition of HDAC4 sensitized a T-ALL cell line to etoposide-induced cell death. In conclusion, our data point to HDAC4 as drug target in childhood ALL, especially in prednisone poor-responders.

    Both acute pancreatitis and diffuse alveolar haemorrhage are rare conditions associated with systemic lupus erythematosus (SLE). In this case report, a 23-year-old female with SLE was diagnosed with lupus-associated pancreatitis and, within a few days and despite initial therapy with pulse methyl-prednisolone, subsequently suffered an acute respiratory failure due to a diffuse alveolar haemorrhage. The patient was admitted to the intensive care unit and treatment was intensified with cyclophosphamide and rituximab, which shortly induced the complete remission of SLE with resolution of both clinical conditions. She completed treatment with six pulses of cyclophosphamide followed by azathioprine, hydroxychloroquine and prednisone at initial doses of 20 mg/d with rapid tapering to 5 mg/d, without relapse of the disease during the following year. This case can illustrate that, even in severe, life-threatening SLE flares, it is possible to avoid high-dose prednisone, which has been associated with severe side effects, including infections. Acute pancreatitis and diffuse alveolar haemorrhage are rare conditions caused by SLE. DAH can be a life-threatening complication, with an early mortality of at least 50%. When facing such severe SLE activity, there is a general tendency to use high doses of prednisone as the initial therapy, maintaining such high doses for long periods of time, even after the clinical situation has subsided. We report a case of a young woman with SLE, suffering from acute pancreatitis and diffuse alveolar haemorrhage, who was successfully treated with pulse methyl-prednisolone, hydroxychloroquine, cyclophosphamide and rituximab, combined with medium doses of prednisone.

    The purpose of this study was to define the maximal tolerated dose (MTD), extramedullary toxicities, and pharmacokinetics of docetaxel combined with high-dose melphalan and carboplatin with autologous hematopoietic progenitor cell support. Fifty-nine patients with advanced refractory malignancy (32 breast cancer, 10 non-Hodgkin lymphoma, 6 germ cell tumors, 4 Hodgkin disease, 4 ovarian cancer, 2 sarcoma, and 1 unknown primary adenocarcinoma) with a median of 3 prior chemotherapy regimens and a median of 3 organs involved were enrolled. Treatment included docetaxel (150-550 mg/m2 infused over 2 hours on day -6), melphalan (150-165 mg/m2 infused over 15 minutes from day -5 to -3), and carboplatin (1000-1300 mg/m2 as a 72-hour continuous infusion from day -5). Five patients died from direct regimen-related organ toxicity (2 capillary leak syndrome, 2 enterocolitis, and 1 hepatic toxicity), and 1 additional patient died from pulmonary aspergillosis. The docetaxel MTD was defined as 400 mg/m 2 , combined with melphalan (150 mg/m2 ) and carboplatin (1000 mg/m2 ). The MTD cohort was expanded to enroll a total of 26 patients, 1 of whom died from toxic enterocolitis. The remaining 25 patients presented the following extramedullary toxicity profile, which was manageable and largely reversible: stomatitis, myoarthralgias, peripheral neuropathy, gastrointestinal and cutaneous toxicities, and syndrome of inappropriate antidiuretic hormone secretion. Docetaxel exhibited linear pharmacokinetics in the dose range tested (150-550 mg/m2 ). Pharmacodynamic correlations were noted between the docetaxel area under the curve and peripheral neuropathy or stomatitis. The response rate among 38 patients with measurable disease was 95%, with 47% complete responses. At a median follow-up of 26 months (range, 7-72 months), the 3-year event-free survival and overall survival were 26% and 36%, respectively. In conclusion, a 4-fold dose escalation of docetaxel, combined with melphalan and

This analysis assesses the cost-effectiveness of modified-release (MR prednisone compared with immediate-release (IR prednisone for the treatment of morning stiffness due to RA. Methods: A health state transition model was used to categorize RA patients into four health states, defined by duration of morning stiffness. The model applied a 1-year time horizon and adopted a UK National Health Service (NHS perspective. Health benefits were measured in quality-adjusted life years (QALYs and the final output was the incremental cost-effectiveness ratio (ICER. Efficacy data were derived from the CAPRA-1 (Circadian Administration of Prednisone in Rheumatoid Arthritis study, drug costs from the British National Formulary (BNF, and utility data from a direct elicitation time-trade-off (TTO study in the general population. Sensitivity analyses were conducted. Results: Mean treatment costs per patient were higher for MR-prednisone (£649.70 than for IR-prednisone (£46.54 for the duration of the model. However, the model generated an incremental QALY of 0.044 in favor of MR-prednisone which resulted in an ICER of £13,577. Deterministic sensitivity analyses did not lead to significant changes in the ICER. Probabilistic sensitivity analysis reported that MR-prednisone had an 84% probability of being cost-effective at a willingness-to-pay threshold of £30,000 per QALY. The model only considers drug costs and there was a lack of comparative long-term data for IR-prednisone

    Seven of 17 children (41%) under 5 years of age with acute granulocytic leukemia (AGL) treated with either cytosine arabinoside-cytoxan (CA-CYT) or Mini-COAP (CA-CYT with vincristine sulfate [VCR] and prednisone) have been in continuous complete remission 4 years or more. CA and CYT were each given in the dosage of 120 mg/m2 intravenously, daily in 3 divided doses, for 4 days. Induction consisted of two courses given at intervals of 2 weeks; during maintenance the courses were repeated at intervals of 4 weeks. In the Mini-COAP regimen, standard 28-day VCR-prednisone therapy was superimposed on CA-CYT induction and 4-day VCR-prednisone pulses were superimposed on CA-CYT maintenance. Transient moderate to severe myelosuppression was frequent; other manifestations of toxicity were mild. Administration of drugs at home was feasible in many instances. Mini-COAP was proved to be an effective therapeutic regimen for young children with AGL and should be considered as initial therapy.

    This study compared the efficacy and safety of high-dose dexamethasone (HD-DXM) and conventional prednisone (PDN) on the largest cohort to date as first-line strategies for newly diagnosed adult primary immune thrombocytopenia (ITP). Patients enrolled were randomized to receive DXM 40 mg/d for 4 days (n = 95, nonresponders received an additional 4-day course of DXM) or prednisone 1.0 mg/kg daily for 4 weeks and then tapered (n = 97). One or 2 courses of HD-DXM resulted in a higher incidence of overall initial response (82.1% vs 67.4%, P = .044) and complete response (50.5% vs 26.8%, P = .001) compared with prednisone. Time to response was shorter in the HD-DXM arm (P < .001), and a baseline bleeding score ≥8 was associated with a decreased likelihood of initial response. Sustained response was achieved by 40.0% of patients in the HD-DXM arm and 41.2% in the PDN arm (P = .884). Initial complete response was a positive indicator of sustained response, whereas presence of antiplatelet autoantibodies was a negative indicator. HD-DXM was generally tolerated better. We concluded that HD-DXM could be a preferred corticosteroid strategy for first-line management of adult primary ITP. This study is registered at www.clinicaltrials.gov as #NCT01356511.

    The role of high-dose chemotherapy (HDC) followed by autologous-progenitor cell transplantation (auto-HPCT) in the treatment of multiple myeloma (MM) continues to evolve in the novel agent era. Administration of high-dose melphalan (HDM) is considered the standard conditioning regimen. Nevertheless, several attempts have recently been made to improve the conditioning phase of the HDC procedure. We reviewed all the reported experiences and illustrated current knowledge in the field of conditioning regimens. For fit MM patients, HDC followed by auto-HPCT remains the standard of care. The available data confirm that melphalan (MEL) 200 mg/m(2) should continue to be considered the gold standard conditioning regimen, with dose reduction based on age and renal function. Targeting exposure to MEL by using area under the curve is a particularly appealing approach that could be explored to maximize efficacy and minimize toxicity of this drug. Other strategies are currently being evaluated in different trials, and the most interesting areas of research involve the incorporation of newer agents like bortezomib (BOR) into conditioning regimens. Moreover, intravenous busulfan has become available and this formulation may reduce toxicity and result in greater efficacy in association with MEL-based conditioning.

    Despite response rates of 30% after high-dose chemotherapy with autologous hematopoietic stem cell transplant, patients with multiple myeloma are not cured. 153Samarium ethylenediaminetetramethylenephosphonate (153Sm-EDTMP; Quadramet) is a short-range, beta-emitting therapeutic radiopharmaceutical with avid skeletal uptake. In total, 12 patients were treated with escalating doses of 153Sm-EDTMP (N=3/group; 6, 12, 19.8, and 30 mCi/kg) and a fixed dose of melphalan (200 mg/m(2)). No dose limiting toxicity was seen. To better standardize the marrow compartment radiation dose, the study was modified such that an additional six patients were treated at a targeted absorbed radiation dose to the red marrow of 40 Gy based on a trace labeled infusion 1 week prior to the therapy. Despite rapid elimination of unbound radiopharmaceutical via kidneys and bladder, no episodes of nephrotoxicity, hemorrhagic cystitis, or delayed radiation nephritis were observed with a median follow-up of 31 months (range 8.5-44). Median times to ANC>0.5 and platelet >20 x 10(6)/l were 12 and 11 days, respectively, with no graft failures. Overall response rate was 94% including seven very good partial responses and five complete responses. Addition of 153Sm EDTMP to melphalan conditioning appears to be safe, well-tolerated and worthy of further study.

    Multiple myeloma (MM) remains an incurable illness affecting nearly 20,000 individuals in the United States per year. High-dose melphalan (HDM) with autologous hematopoietic stem cell support (ASCT) is one of the mainstays of therapy for younger patients, but little advancement has been made with regards to conditioning regimens. We opted to combine 153Samarium ethylenediaminetetramethylenephosphonate (153Sm-EDTMP), a radiopharmaceutical approved for the palliation of pain caused by metastatic bone lesions, with HDM and ASCT in a phase II study. Individualized doses of 153Sm were based on dosimetry and were calculated to deliver 40 Gy to the bone marrow. The therapeutic dose of 153Sm-EDTMP was followed by HDM and ASCT. Forty-six patients with newly diagnosed or relapsed disease were treated. Study patients were compared to 102 contemporaneously patients treated with HDM and ASCT. Fifty-nine percent of study patients achieved a very good partial response or better. With a median follow-up of 7.1 years, the median overall survival and progression free survival from study registration was 6.2 years (95%CI 4.6–7.5 years) and 1.5 years (1.1–2.2 years), respectively, which compared favorably to contemporaneously treated non-study patients. Addition of high-dose 153Sm EDTMP to melphalan conditioning appears to be safe, well tolerated and worthy of further study in the context of novel agents and in the phase III setting. PMID:20513117

    Single autologous hematopoietic cell transplant (AHCT) with high-dose melphalan prolongs survival in patients with multiple myeloma but is not curative. We conducted a study of intensive single AHCT using tandem chemomobilization with CY and etoposide followed by high-dose conditioning with melphalan 200 mg/m2 plus carmustine 15 mg/kg. One hundred and eighteen patients in first consolidation (CON1) and 58 patients in relapse (REL) were transplanted using this intensified approach. Disease response improved from 32% very good PR (VGPR) + CR pre-mobilization to 76% VGPR + CR post transplant in CON1. With a median follow-up of 4.7 years, the median EFS was 2.8 years, and the median OS was 5.1 years in CON1. OS from time of transplant was significantly shorter for REL (3.4 years) compared with CON1 (5.1 years; P = 0.02). However, OS from time of diagnosis was similar in REL (6.1 years) and CON1 (6.0 years; P = 0.80). The 100-day non-relapse mortality in the CON1 and REL groups was 0% and 7%, respectively. In summary, intensified single AHCT with tandem chemo-mobilization and augmented high-dose therapy is feasible in multiple myeloma and leads to high-quality response rates. PMID:21602899

    The fusion protein L19mTNF (mouse TNF and human antibody fragment L19 directed to fibronectin extra domain B) selectively targets the tumor vasculature, and in combination with melphalan induces a long-lasting T-cell therapeutic response and immune memory in murine models. Increasing evidence suggests that natural killer (NK) cells act to promote effective T-cell-based antitumor responses. We have analyzed the role of NK cells and dendritic cells (DCs) on two different murine tumor models: WEHI-164 fibrosarcoma and C51 colon carcinoma, in which the combined treatment induces high and low rejection rates, respectively. In vivo NK-cell depletion strongly reduced the rejection of WEHI-164 fibrosarcoma and correlated with a decrease in mature DCs, CD4(+) , and CD8(+) T cells in the tumor-draining LNs and mature DCs and CD4(+) T cells in the tumor 40 h after initiation of the therapy. NK-cell depletion also resulted in the impairment of the stimulatory capability of DCs derived from tumor-draining LNs of WEHI-164-treated mice. Moreover, a significant reduction of M2-type infiltrating macrophages was detected in both tumors undergoing therapy. These results suggest that the efficacy of L19mTNF/melphalan therapy is strongly related to the early activation of NK cells and DCs, which are necessary for an effective T-cell response. © 2017 WILEY-VCH Verlag GmbH & Co.

    Objective: To assess safety and efficacy of deflazacort (DFZ) and prednisone (PRED) vs placebo in Duchenne muscular dystrophy (DMD). Methods: This phase III, double-blind, randomized, placebo-controlled, multicenter study evaluated muscle strength among 196 boys aged 5–15 years with DMD during a 52-week period. In phase 1, participants were randomly assigned to receive treatment with DFZ 0.9 mg/kg/d, DFZ 1.2 mg/kg/d, PRED 0.75 mg/kg/d, or placebo for 12 weeks. In phase 2, placebo participants were randomly assigned to 1 of the 3 active treatment groups. Participants originally assigned to an active treatment continued that treatment for an additional 40 weeks. The primary efficacy endpoint was average change in muscle strength from baseline to week 12 compared with placebo. The study was completed in 1995. Results: All treatment groups (DFZ 0.9 mg/kg/d, DFZ 1.2 mg/kg/d, and PRED 0.75 mg/kg/d) demonstrated significant improvement in muscle strength compared with placebo at 12 weeks. Participants taking PRED had significantly more weight gain than placebo or both doses of DFZ at 12 weeks; at 52 weeks, participants taking PRED had significantly more weight gain than both DFZ doses. The most frequent adverse events in all 3 active treatment arms were Cushingoid appearance, erythema, hirsutism, increased weight, headache, and nasopharyngitis. Conclusions: After 12 weeks of treatment, PRED and both doses of DFZ improved muscle strength compared with placebo. Deflazacort was associated with less weight gain than PRED. Classification of evidence: This study provides Class I evidence that for boys with DMD, daily use of either DFZ and PRED is effective in preserving muscle strength over a 12-week period.

    Cereblon, a member of the cullin 4 ring ligase complex (CRL4), is the molecular target of the immunomodulatory drugs (IMiDs) lenalidomide and pomalidomide and is required for the antiproliferative activity of these agents in multiple myeloma (MM) and immunomodulatory activity in T cells. Cereblon's central role as a target of lenalidomide and pomalidomide suggests potential utility as a predictive biomarker of response or resistance to IMiD therapy. Our studies characterized a cereblon monoclonal antibody CRBN65, with high sensitivity and specificity in Western analysis and immunohistochemistry that is superior to commercially available antibodies. We identified multiple cereblon splice variants in both MM cell lines and primary cells, highlighting challenges with conventional gene expression assays given this gene complexity. Using CRBN65 antibody and TaqMan quantitative reverse transcription polymerase chain reaction assays, we showed lack of correlation between cereblon protein and mRNA levels. Furthermore, lack of correlation between cereblon expression in MM cell lines and sensitivity to lenalidomide was shown. In cell lines made resistant to lenalidomide and pomalidomide, cereblon protein is greatly reduced. These studies show limitations to the current approaches of cereblon measurement that rely on commercial reagents and assays. Standardized reagents and validated assays are needed to accurately assess the role of cereblon as a predictive biomarker.

    Despite the high response rates of individuals with myelodysplastic syndrome (MDS) with deletion of chromosome 5q (del(5q)) to treatment with lenalidomide (LEN) and the recent identification of cereblon (CRBN) as the molecular target of LEN, the cellular mechanism by which LEN eliminates MDS clones remains elusive. Here we performed an RNA interference screen to delineate gene regulatory networks that mediate LEN responsiveness in an MDS cell line, MDSL. We identified GPR68, which encodes a G-protein-coupled receptor that has been implicated in calcium metabolism, as the top candidate gene for modulating sensitivity to LEN. LEN induced GPR68 expression via IKAROS family zinc finger 1 (IKZF1), resulting in increased cytosolic calcium levels and activation of a calcium-dependent calpain, CAPN1, which were requisite steps for induction of apoptosis in MDS cells and in acute myeloid leukemia (AML) cells. In contrast, deletion of GPR68 or inhibition of calcium and calpain activation suppressed LEN-induced cytotoxicity. Moreover, expression of calpastatin (CAST), an endogenous CAPN1 inhibitor that is encoded by a gene (CAST) deleted in del(5q) MDS, correlated with LEN responsiveness in patients with del(5q) MDS. Depletion of CAST restored responsiveness of LEN-resistant non-del(5q) MDS cells and AML cells, providing an explanation for the superior responses of patients with del(5q) MDS to LEN treatment. Our study describes a cellular mechanism by which LEN, acting through CRBN and IKZF1, has cytotoxic effects in MDS and AML that depend on a calcium- and calpain-dependent pathway.

  6. Multiple myeloma in the elderly: when to treat, when to go to transplant.

    2010-10-01

    Until recently, standard treatment of multiple myeloma (MM) in elderly patients who were not candidates for autologous stem cell transplantation was with the combination of melphalan plus prednisone (MP). Novel agents (thalidomide, lenalidomide, bortezomib) are dramatically changing frontline therapy of MM. Randomized studies have shown the superiority of adding one novel agent to MP, either thalidomide (MPT) or bortezomib (MPV). The combination of lenalidomide with low doses of dexamethasone is another attractive alternative. Recent results show that maintenance therapy with low-dose lenalidomide may prolong progression-free survival. The objective of these improved treatment regimens should be to achieve complete response, as in younger patients. However, toxicity is a significant concern, and doses of thalidomide and of myelotoxic agents should be reduced in patients who are older than 75 years or who have poor performance status. Weekly bortezomib appears to induce severe peripheral neuropathy less frequently than the same agent administered twice weekly. Autologous stem cell transplantation is feasible in selected fit patients over 65 years of age, and its results are improved by the addition of novel agents before and after high-dose therapy. However, considering the progress in non-intensive therapy, autologous transplantation should not currently be offered to elderly patients outside of a clinical trial.

    Autologous stem cell transplantation (ASCT) after high-dose melphalan conditioning is considered a standard of care procedure for patients with multiple myeloma (MM). Current formulations of melphalan (eg, Alkeran for Injection [melphalan hydrochloride]; GlaxoSmithKline, Research Triangle Park, NC, USA) have marginal solubility and limited chemical stability upon reconstitution. Alkeran requires the use of propylene glycol as a co-solvent, which itself has been reported to cause such complications as metabolic/renal dysfunction and arrhythmias. EVOMELA (propylene glycol-free melphalan HCl; Spectrum Pharmaceuticals, Inc., Irvine, CA, USA) is a new i.v. melphalan formulation that incorporates Captisol (Ligand Pharmaceuticals, Inc., La Jolla, CA, USA), a specially modified cyclodextrin that improves the solubility and stability of melphalan and eliminates the need for propylene glycol. This new formulation has been shown to be bioequivalent to Alkeran. EVOMELA (200 mg/m(2)) was administered as 2 doses of 100 mg/m(2) each in a phase IIb, open-label, multicenter study to confirm its safety and efficacy as a high-dose conditioning regimen for patients with MM undergoing ASCT. At 5 centers, 61 patients (26 women) with a median age of 62 years (range, 32-73) were enrolled. All patients achieved myeloablation with a median time of 5 days post-ASCT, and all successfully achieved neutrophil and platelet engraftment with median times of 12 days post-ASCT and 13 days post-ASCT, respectively; treatment-related mortality on day 100 was 0%. Overall response rate (according to independent, blinded review) was high (100%), with an overall complete response rate of 21% (13% stringent complete response; 8% complete response) and overall partial response rate of 79% (61% very good partial response; 18% partial response). The incidence of grade 3 mucositis and stomatitis was low (10% and 5%, respectively) with no grade 4 mucositis or stomatitis reported (graded according to National

Andrea Hospital, Vercelli, 2Rheumatology Outpatient Clinic, Novara, 3Primula Multimedia S.p.A, Pisa, Italy Abstract: To date, rheumatoid arthritis (RA remains a debilitating, life-threatening disease. One major concern is morning symptoms (MS, as they considerably impair the patients’ quality of life and ability to work. MS change in a circadian fashion, resembling the fluctuations of inflammatory cytokines such as interleukin-6, whose levels are higher in RA patients compared to healthy donors. Conversely, serum levels of the potent anti-inflammatory glucocorticoid cortisol are similar to that of healthy subjects, suggesting an imbalance that sustains a pro-inflammatory state. From a therapeutic point of view, administering synthetic glucocorticoids (GCs to RA patients represents an optimal strategy to provide for the inadequate levels of cortisol. Indeed, due to their high efficacy in RA, GCs remain a cornerstone more than 60 years after their first introduction, and despite the development of a wide range of targeted agents. However, to improve safety, low-dose GCs have been introduced, that have demonstrated high efficacy in reducing disease activity, radiological progression, and improving patients’ signs and symptoms especially in early RA when added to conventional disease-modifying antirheumatic drugs. A further improvement has been provided by the development of modified-release prednisone, which, by taking advantage of the circadian fluctuations of inflammatory cytokines, cortisol and MS, is given at bedtime to be released approximately 4 hours later. Several studies have already demonstrated the efficacy of this agent on disease activity, MS, and quality of life in the setting of established RA. Moreover, preliminary studies have shown that this new formulation not only has no impact on the adrenal function, but likely improves it. This

    Cereblon (CRBN), the molecular target of lenalidomide and pomalidomide, is a substrate receptor of the cullin ring E3 ubiquitin ligase complex, CRL4(CRBN) . T cell co-stimulation by lenalidomide or pomalidomide is cereblon dependent: however, the CRL4(CRBN) substrates responsible for T cell co-stimulation have yet to be identified. Here we demonstrate that interaction of the transcription factors Ikaros (IKZF1, encoded by the IKZF1 gene) and Aiolos (IKZF3, encoded by the IKZF3 gene) with CRL4(CRBN) is induced by lenalidomide or pomalidomide. Each agent promotes Aiolos and Ikaros binding to CRL4(CRBN) with enhanced ubiquitination leading to cereblon-dependent proteosomal degradation in T lymphocytes. We confirm that Aiolos and Ikaros are transcriptional repressors of interleukin-2 expression. The findings link lenalidomide- or pomalidomide-induced degradation of these transcriptional suppressors to well documented T cell activation. Importantly, Aiolos could serve as a proximal pharmacodynamic marker for lenalidomide and pomalidomide, as healthy human subjects administered lenalidomide demonstrated Aiolos degradation in their peripheral T cells. In conclusion, we present a molecular model in which drug binding to cereblon results in the interaction of Ikaros and Aiolos to CRL4(CRBN) , leading to their ubiquitination, subsequent proteasomal degradation and T cell activation.

    Fifteen consecutive patients with refractory adult acute leukemia (RAAL) were treated with a combination of high-dose, continuous-infusion cyclophosphamide, cytarabine, vincristine, and prednisone (Hi-COAP). The initial nine patients received cyclophosphamide 350 mg/m2 as a 24-hour intravenous (IV) infusion over 5 days; cytarabine, 100 mg/m2 IV bolus every 12 hours for ten doses; vincristine, 2.0 mg IV bolus on day 1; and prednisone, 100 mg orally for 7 days. The last six patients had the cyclophosphamide infusion lengthened to 7 days, and the cytarabine increased to 14 doses. All patients were evaluable for toxicity and response. Seven patients (47%) obtained a complete remission and six patients (40%) a partial remission. Median duration of all remissions has been 7.0 months with a range of 1 to 32 months. Toxicity has been limited to primarily myelosuppression with no hemorrhagic cystitis, central nervous system (CNS), hepatic, or pulmonary toxicity noted. Gastrointestinal toxicity was mild, with no effect on nutritional status noted. Median duration of complete responders was 8.5 months. Thus, Hi-COAP demonstrates promising efficacy with minimal toxicity in RAAL and warrants further exploration in multiinstitutional trials.

    Glucocorticoids are among the most commonly used drugs. They are widely administered for acute and chronic musculoskeletal pain, as well as for several other pain syndromes, although their therapeutic use is sometimes diverted for doping purposes. Their time-course effects on hormonal and inflammatory responses nevertheless remain poorly understood, both at rest and during exercise. We therefore studied the alterations induced by 1 week of prednisone treatment (60 mg daily) in recreationally trained male athletes after 2 days (i. e., acute) and 7 days (i. e., short-term). Hormonal (i. e., DHEA, DHEA-S, aldosterone, and testosterone) and pro- and anti-inflammatory markers (i. e., IL-6, IL-10, and IL-1β) were investigated at rest and after resistance exercise. A significant decrease in DHEA and DHEA-S (pprednisone intake. A significant increment in IL-10 and a significant decrement in IL-6 (pprednisone both at rest and during exercise, without significant change in IL-1β. Continued prednisone treatment led to another significant decrease in both DHEA and DHEA-S (pprednisone were maximal and stable from the beginning of treatment, both in rest and exercise conditions. However, hormonal concentrations continued to decline during short-term intake. Further studies are needed to determine the effects of hormonal time-course alterations with longer glucocorticoid treatment and the clinical consequences.

    A 4-year-old, spayed female toy fox terrier developed multiple epidermal hamartomas and squamous cell carcinomas in situ following chronic immunosuppressive therapy with prednisone and cyclosporine for management of an immune-mediated nonregenerative anaemia. Immunohistochemical staining was positive for papillomavirus antigen within both benign (n = 19) and malignant (n = 8) cutaneous lesions that developed during a 3-year period of observation, with positive staining most often seen in keratinocytes in the granular cell layer. Treatment of the papillomavirus infection with interferon-alpha was discontinued after 2 weeks because of diarrhoea and a further increase in liver enzymes. The cutaneous lesions of this dog persisted and new lesions developed during the year following discontinuation of both cyclosporine and prednisone. This is the first reported case of papillomavirus-associated squamous cell carcinoma in situ developing in a dog following chronic administration of cyclosporine and prednisone.

    Forty patients (median age, 31 years; range, 20 to 63) with Hodgkin lymphoma underwent an allogeneic stem cell transplant with the gemcitabine-fludarabine-melphalan reduced-intensity conditioning regimen. Thirty-one patients (77%) had undergone a prior autologous stem cell transplant, with a median time to progression after transplant of 6 months (range, 1 to 68). Disease status at transplant was complete remission/complete remission, undetermined (n = 23; 57%), partial remission (n = 14; 35%), and other (n = 3; 8%). Twenty-six patients (65%) received brentuximab vedotin before allotransplant. The overall complete response rate before allotransplant was 65% in brentuximab-treated patients versus 42% in brentuximab-naive patients (P = .15). At the latest follow-up (October 2015) 31 patients were alive. The median follow-up was 41 months (range, 5 to 87). Transplant-related mortality rate at 3 years was 17%. Pulmonary, skin toxicities, and nausea were seen in 13 (33%), 11 (28%), and 37 (93%) patients, respectively. At 3 years, estimates for overall and progression-free survival were 75% (95% CI, 57% to 86%) and 54% (95% CI, 36% to 70%). Overall incidence for disease progression was 28% (95% CI, 16% to 50%). We believe the gemcitabine-fludarabine-melphalan regimen allows moderate dose intensification with acceptable morbidity and mortality. The inclusion of gemcitabine affected nausea, pulmonary, and likely skin toxicity. Exposure to brentuximab vedotin allowed more patients to reach allogeneic stem cell transplantation in complete remission. With over 50% of patients progression-free at 3 years, allogeneic stem cell transplantation with reduced-intensity conditioning remains an effective and relevant treatment option for Hodgkin lymphoma in the brentuximab vedotin era.

    Full Text Available Novel agents such as thalidomide, lenalidomide, and bortezomib have been shown to possess potent activity against multiple myeloma. However, the treatment strategy for patients who acquired resistance to these agents has not been established. In addition to switching drug classes, intensified treatment strategy, including increase in the dosage of current agents and addition of other agents, may be considered for these patients. We here describe 2 myeloma patients with acquired resistance to bortezomib or lenalidomide, in whom add-on therapy with low-dose cyclophosphamide was effective and tolerable. These cases suggest that add-on therapy with cyclophosphamide is one of the treatment options to overcome resistance to novel agents in patients with multiple myeloma. A larger prospective study is needed to clarify the efficacy and safety of this strategy for novel agent-resistant multiple myeloma.

    Objective A subset analysis of the randomised, phase 3, MDS-004 study to evaluate outcomes in patients with International Prognostic Scoring System (IPSS)-defined Low-/Intermediate (Int)-1-risk myelodysplastic syndromes (MDS) with isolated del(5q). Methods Patients received lenalidomide 10 mg/d (days 1–21; n = 47) or 5 mg/d (days 1–28; n = 43) on 28-d cycles or placebo (n = 45). From the placebo and lenalidomide 5 mg groups, 84% and 58% of patients, respectively, crossed over to lenalidomide 5 or 10 mg at 16 wk, respectively. Results Rates of red blood cell-transfusion independence (RBC-TI) ≥182 d were higher in the lenalidomide 10 mg (57.4%; P < 0.0001) and 5 mg (37.2%; P = 0.0001) groups vs. placebo (2.2%). Cytogenetic response rates (major + minor responses) were 56.8% (P < 0.0001), 23.1% (P = 0.0299) and 0%, respectively. Two-year cumulative risk of acute myeloid leukaemia progression was 12.6%, 17.4% and 16.7% in the lenalidomide 10 mg, 5 mg, and placebo groups, respectively. In a 6-month landmark analysis, overall survival was longer in lenalidomide-treated patients with RBC-TI ≥182 d vs. non-responders (P = 0.0072). The most common grade 3–4 adverse event was myelosuppression. Conclusions These data support the clinical benefits and acceptable safety profile of lenalidomide in transfusion-dependent patients with IPSS-defined Low-/Int-1-risk MDS with isolated del(5q).

    This international phase III, randomized, placebo-controlled, double-blind study assessed the efficacy and safety of lenalidomide in RBC transfusion-dependent patients with International Prognostic Scoring System lower-risk non-del(5q) myelodysplastic syndromes ineligible for or refractory to erythropoiesis-stimulating agents. In total, 239 patients were randomly assigned (2:1) to treatment with lenalidomide (n = 160) or placebo (n = 79) once per day (on 28-day cycles). The primary end point was the rate of RBC transfusion independence (TI) ≥ 8 weeks. Secondary end points were RBC-TI ≥ 24 weeks, duration of RBC-TI, erythroid response, health-related quality of life (HRQoL), and safety. RBC-TI ≥ 8 weeks was achieved in 26.9% and 2.5% of patients in the lenalidomide and placebo groups, respectively (P 500 mU/mL). At week 12, mean changes in HRQoL scores from baseline did not differ significantly between treatment groups, which suggests that lenalidomide did not adversely affect HRQoL. Achievement of RBC-TI ≥ 8 weeks was associated with significant improvements in HRQoL (P < .01). The most common treatment-emergent adverse events were neutropenia and thrombocytopenia. Lenalidomide yields sustained RBC-TI in 26.9% of RBC transfusion-dependent patients with lower-risk non-del(5q) myelodysplastic syndromes ineligible for or refractory to erythropoiesis-stimulating agents. Response to lenalidomide was associated with improved HRQoL. Treatment-emergent adverse event data were consistent with the known safety profile of lenalidomide. © 2016 by American Society of Clinical Oncology.

    1α,25-Dihydroxyvitamin D3, (1,25-D3) the biologically active form of vitamin-D, is well established as a cancer cell growth inhibitor in addition to maintaining bone mineralization. In breast cancer cells, inhibitory effects on angiogenesis, and metastasis have been observed together with enhancement of apoptosis and induction of cell cycle arrest. There is a correlation between vitamin-D receptor expression on breast cancer cells and patient survival. However vitamin-D resistance and hypercalcaemia are key limiting factors in clinical use. The IMiD(®) immunomodulatory drug lenalidomide, (Revlimid(®), CC-5013) used in myeloma, can also modulate apoptotic and growth signalling. We studied whether lenalidomide treated breast cancer cells would acquire sensitivity to 1,25-D3 with resulting growth inhibition. The cell lines MCF-12A, MCF-7 and MDA-MB-231, representing non-tumorogenic, tumorogenic, and vitamin-D resistant lines respectively were treated with lenalidomide and/or 1,25-D3(at 100 nM). Whereas lenalidomide alone had no effect on cell growth, a 50% inhibition of cell growth by 1,25-D3 was achieved with additional 1 μM lenalidomide in resistant cells. This effect was through apoptosis measured by PARP cleavage and annexin-V expression. An apoptosis protein array showed that the 1,25-D3 and lenalidomide combination increased pro-apoptotic proteins (phosphorylated p53) and decreased BCL-2 expression. BCL-2 inhibition is proposed as a mechanism of action for the combined drugs in the MDA-MB-231 cell line. In vitamin D resistant cell lines MCF-7VDR and HBL-100 where the combination does not affect BCL-2-no inhibitory effect is observed. These results demonstrate the potential for the combinatorial use of lenalidomide and 1,25-D3 for vitamin D refractory tumours.

    Objective:To explore the effect of Ginkgo biloba extract (EGb) combined with prednisone on bronchoalveolar lavage fluid (BALF) related cytokines in patients with idiopathic pulmonary fibrosis (IPF).Methods: A total of 60 patients with IPF who were admitted in our hospital from March, 2015 to March, 2016 were included in the study and randomized into the observation group and the control group with 30 cases in each group. The patients in the two groups were given oxygen inhalation, bronchodilator agents, phlegm dissipating and asthma relieving, anti-infection, and other supporting treatments. The patients in the control group were orally given prednisone (0.5 mg/kg•d), continuously for 4 weeks, then in a dose of 0.25 mg/kg•d, continuously for 8 weeks, and finally the dosage was reduced to 0.125 mg/kg•d. On this basis, the patients in the observation group were given additional EGb,ie. ginkgo leaf capsule, 1 g/time, 3 times/d, continuously for 12 weeks. The efficacy was evaluated after 12-week treatment. ELISA was used to detect the levels of TNF-α, IL-4, IL-10, and IFN-γ in BALF. The radioimmunoassay was used to determine the levels of serum HA, ColⅢ, PCⅢ, and LN. The pulmonary function detector was used to measure TLC, VC, DLCO, and 6MWT.Results:After treatment, TNF-α level in the control group was significantly reduced when compared with before treatment (P0.05), while HA, ColⅢ, PCⅢ, and LN levels in the observation group were significantly reduced when compared with before treatment (P<0.05), and the difference between the two groups was statistically significant (P<0.05). After treatment, TLC, VC, DLCO, and 6MWT in the two groups were significantly improved when compared with before treatment (P<0.05), and the difference between the two groups was statistically significant (P<0.05).Conclusions:EGb combined with prednisone can effectively enhance the levels of TNF-α, IL-4, IL-10, and IFN-γin BALF in patients with IPF, and improve the pulmonary

    This phase I-II study explored safety, immunomodulatory and clinical effects of lenalidomide (weeks 1-16) and alemtuzumab (weeks 5-16) in 23 patients with refractory chronic lymphocytic leukemia. Most patients had Rai stage III/IV disease and were heavily pretreated (median 4 prior therapies), and 61% had del(17p)/del(11q). Eleven of 19 evaluable patients (58%) responded, with a median response duration of 12 months (1-29+); time to progression was short in non-responders. Lenalidomide had a narrow therapeutic dose range, 2.5 mg/day was not efficient, and maximum tolerated dose was 5 mg/day. Grade 3-4 neutropenia and thrombocytopenia occurred in 84 and 55%, 30% had febrile neutropenia, and CMV-reactivation requiring valganciclovir occurred in 30% of patients. The frequency of proliferating (Ki67(+)) CD8(+) T cells was increased at week 4, with further increase in both the CD4(+) and CD8(+) subsets (p low-dose lenalidomide and alemtuzumab induced major perturbations of T cells, including increased proliferative activity and cytotoxic potential.

    Deletion of the long arm of chromosome 5, del(5q), is the most prevalent cytogenetic abnormality in patients with myelodysplastic syndromes (MDS). In isolation, it is traditionally associated with favorable prognosis compared with other subtypes of MDS. However, owing to the inherent heterogeneity of the disease, prognosis for patients with del(5q) MDS is highly variable depending on the presence of factors such as additional chromosomal abnormalities, >5 % blasts in the bone marrow (BM), or transfusion dependence. Over recent years, the immunomodulatory drug lenalidomide has demonstrated remarkable efficacy in patients with del(5q) MDS. Advances in the understanding of the pathogenesis of the disease have suggested that lenalidomide targets aberrant signaling pathways caused by haplosufficiency of specific genes in a commonly deleted region on chromosome 5 (e.g., SPARC, RPS14, Cdc25C, and PP2A). As a result, the agent specifically targets del(5q) clones while also promoting erythropoiesis and repopulation of the bone marrow in normal cells. This review discusses recent developments in the understanding of the mechanism of action of lenalidomide, and how this underlies favorable outcomes in patients with del(5q) MDS. In addition, we discuss how improved understanding of the mechanism of disease will facilitate clinicians' ability to predict/monitor response and identify patients at risk of relapse.

    The most common means of mobilizing autologous stem cells is G-CSF alone or combined with cyclophosphamide (CY) to obtain sufficient CD34+ cells for one to two transplants. There are few prospective, randomized studies investigating mobilization regimens in multiple myeloma (MM), especially after lenalidomide-based induction. We designed this prospective, randomized study to compare low-dose CY 2 g/m2+G-CSF (arm A) and G-CSF alone (arm B) after lenalidomide-based up-front induction in MM. Of the 80 initially randomized patients, 69 patients were evaluable, 34 and 35 patients in arms A and B, respectively. The primary end point was the proportion of patients achieving a yield of ⩾3 × 106/kg CD34+ cells with 1−2 aphereses, which was achieved in 94% and 77% in arms A and B, respectively (P=0.084). The median number of aphereses needed to reach the yield of ⩾3 × 106/kg was lower in arm A than in arm B (1 vs 2, P=0.035). Two patients needed plerixafor in arm A and five patients in arm B (P=0.428). Although CY-based mobilization was more effective, G-CSF alone was successful in a great majority of patients to reach the defined collection target after three cycles of lenalidomide-based induction.

    Full Text Available The advances in the understanding of the pathogenesis of multiple myeloma and the mechanism of drug resistance have led to the development of novel targeted therapies that are able to overcome resistance and show additive or synergistic effects with old chemotherapeutic agents. Thalidomide, its immunomodulatory derivative lenalidomide, and the proteasome inhibitor bortezomib, in combination with oral melphalan in the elderly and with intravenous melphalan in younger patients, are changing the traditional treatment paradigm of multiple myeloma. High-dose melphalan followed by autologous stem cell transplantation in the younger patients and oral melphalan-prednisone-thalidomide in the elderly are the standard of care for newly diagnosed multiple myeloma. In younger patients, combinations incorporating thalidomide or lenalidomide or bortezomib significantly increase the pre-transplant response rate before high-dose melphalan and autologous transplantation, and may further improve the response rate and survival achieved after transplant. Prospective randomized studies incorporating new agents and stratifying patients based on cytogenetic abnormalities, are needed to define the therapeutic algorithm in high-risk disease.O avanço do conhecimento da patogênese do mieloma múltiplo e do mecanismo de resistência a drogas propiciou o desenvolvimento de novas terapias alvo que vençam a resistência e apresentem efeitos sinérgicos e aditivos aos velhos agentes quimioterápicos.

    The value of immunotherapy as an adjuvant to chemotherapy for advanced breast cancer is an unsettled question. To clarify this issue, 71 women with measurable or evaluable metastatic breast cancer were randomized to receive cyclophosphamide, 5-fluorouracil, and prednisone (CFP) with or without methanol-extracted residue of Bacillus Calmette-Guerin (MER). The total regression rates were 52% (CFP) and 39% (CFP + MER), including complete regression rates of 13% (CFP) and 65% (CFP + MER). The median duration of regressions for CFP-treated patients was 257-261 days and for CFP + MER-treated patients was 385 days. The median time to progression was 248-261 days in the CFP group and 159 days in the CFP-MER group. Projected median survival for both treatment groups is 20 months. Immunotherapy (MER) as used in this study does not appear to augment regression rates or vurvival for patients with advanced breast cancer receiving CFP.

    Adults (274) with acute leukemia (AML) were randomly assigned to one of three treatment regimens: vincristine, prednisone, cytarabine--(1) 100 mg/sq m/day with cyclophosphamide (COAP); (2) 100 mg/sq m/day with daunorubicin (DOAP); and 200 mg/sq m/day (OAP). Cytarabine was infused continuously for five days. Patients entering complete remission randomly received maintenance treatment with COAP or OAP. For 197 previously untreated AML patients given COAP, DOAP, or OAP, remission rates were 37%, 35%, and 43%, respectively; median lengths, 40, 45, and 90 weeks; median survival, 7, 11, and 8 weeks. No statistically significant difference was found among treatments. Therefore, adding cyclophosphamide or daunorubicin, or using the COAP regimen with continuously infused cytarabine, produced no significant improvement over previously reported regimens. There was no significant difference in remission lengths in previously untreated AML patients maintained on OAP (median 81 weeks) or COAP (median 65 weeks).

    In previous clinical trials of childhood acute lymphoblastic leukemia (ALL), dexamethasone resulted in higher event-free survival rates than prednisone, presumably due to greater central nervous system penetration. Dexamethasone's association with long-term neurocognitive toxicity is unknown. In this multisite study, we measured neurocognitive functioning in 92 children with standard-risk ALL, 1 to 9.99 years at diagnosis, at a mean of 9.8 years after randomization to prednisone (n = 41) or dexamethasone (n = 51) on Children's Cancer Group (CCG) 1922. No significant overall differences in mean neurocognitive and academic performance scores were found between the prednisone and dexamethasone groups after adjusting for age, sex, and time since diagnosis. The exception was that patients receiving dexamethasone scored one-third of a standard deviation worse on word reading (98.8 +/- 1.7 vs 104.9 +/- 1.8; P = .02). There were no group differences in the distribution of test scores or the parents' report of neurologic complications, psychotropic drug use, and special education. Further analyses suggested for the dexamethasone group, older age of diagnosis was associated with worse neurocognitive functioning; for the prednisone group, younger age at diagnosis was associated with worse functioning. In conclusion, our study did not demonstrate any meaningful differences in long-term cognitive functioning of childhood ALL patients based on corticosteroid randomization. This study is registered with http://www.clinicaltrials.gov under NCT00085176.

    Full Text Available BACKGROUND: The number of promising therapeutic interventions for Duchenne Muscular Dystrophy (DMD is increasing rapidly. One of the proposed strategies is to use drugs that are known to act by multiple different mechanisms including inducing of homologous fetal form of adult genes, for example utrophin in place of dystrophin. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we have treated mdx mice with arginine butyrate, prednisone, or a combination of arginine butyrate and prednisone for 6 months, beginning at 3 months of age, and have comprehensively evaluated the functional, biochemical, histological, and molecular effects of the treatments in this DMD model. Arginine butyrate treatment improved grip strength and decreased fibrosis in the gastrocnemius muscle, but did not produce significant improvement in muscle and cardiac histology, heart function, behavioral measurements, or serum creatine kinase levels. In contrast, 6 months of chronic continuous prednisone treatment resulted in deterioration in functional, histological, and biochemical measures. Arginine butyrate-treated mice gene expression profiling experiments revealed that several genes that control cell proliferation, growth and differentiation are differentially expressed consistent with its histone deacetylase inhibitory activity when compared to control (saline-treated mdx mice. Prednisone and combination treated groups showed alterations in the expression of genes that control fibrosis, inflammation, myogenesis and atrophy. CONCLUSIONS/SIGNIFICANCE: These data indicate that 6 months treatment with arginine butyrate can produce modest beneficial effects on dystrophic pathology in mdx mice by reducing fibrosis and promoting muscle function while chronic continuous treatment with prednisone showed deleterious effects to skeletal and cardiac muscle. Our results clearly indicate the usefulness of multiple assays systems to monitor both beneficial and toxic effects of drugs with

    Lenalidomide is an immunomodulatory compound with high clinical activity in multiple myeloma. Lenalidomide binding to the Cereblon (CRBN) E3 ubiquitin ligase results in targeted ubiquitination and degradation of the lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) leading to growth inhibition of multiple myeloma cells. Recently, Basigin (BSG) was identified as another protein regulated by CRBN that is involved in the activity of lenalidomide. Here, we analyzed the prognostic value of IKZF1, IKZF3, CRBN and BSG mRNA expression levels in pretreatment plasma cells from 60 patients with newly diagnosed multiple myeloma uniformly treated with lenalidomide in combination with intensive chemotherapy within a clinical trial. We found that IKZF1 mRNA expression levels are significantly associated with progression-free survival (PFS). Patients in the lowest quartile (Q1) of IKZF1 expression had a superior PFS compared with patients in the remaining quartiles (Q2-Q4; 3-year PFS of 86 vs 51%, P=0.01). This translated into a significant better overall survival (100 vs 74%, P=0.03). Subgroup analysis revealed a significant impact of IKZF1, IKZF3 and BSG expression levels on PFS in cytogenetically defined standard-risk but not high-risk patients. Our data suggest a prognostic role of IKZF1, IKZF3 and BSG expression levels in lenalidomide-treated multiple myeloma.Leukemia advance online publication, 20 January 2017; doi:10.1038/leu.2016.384.

    The objective of this study was to compare infusion-related reactions and outcomes of using subcutaneous (subQ) alemtuzumab versus intravenous (i.v.) alemtuzumab as graft-versus-host disease (GVHD) prophylaxis for matched unrelated donor stem cell transplantations. Outcomes include incidence of cytomegalovirus (CMV)/Epstein-Barr (EBV) viremia, development of CMV disease or post-transplantation lymphoproliferative disorder, fatal infections, acute and chronic GVHD, time to engraftment, relapse rate, and survival. We conducted a retrospective study of all adult matched unrelated donor stem cell transplantations patients who received fludarabine/melphalan with subQ or i.v. alemtuzumab in combination with tacrolimus as part of their conditioning for unrelated donor transplantation at New York-Presbyterian/Weill Cornell Medical Center from January 1, 2012 to March 21, 2014. Alemtuzumab was administered at a total cumulative dose of 100 mg (divided over days -7 to -3). Forty-six patients received an unrelated donor stem cell transplantation with fludarabine/melphalan and either subQ (n = 26) or i.v. (n = 20) alemtuzumab in combination with tacrolimus. Within the evaluable population, 130 subQ and 100 i.v. alemtuzumab doses were administered. For the primary outcome, ≥grade 2 infusion-related reactions occurred in 11 (8%) versus 25 (25%) infusions in the subQ and i.v. cohorts, respectively (P = .001). Overall, 12 injections (9%) in the subQ arm versus 26 infusions (26%) in the i.v. arm experienced an infusion-related reaction of any grade (P = .001). There were no significant differences between the subQ and i.v. arms in rates of reactivation of CMV/EBV, development of CMV disease or post-transplantation lymphoproliferative disorder, fatal infections, acute and chronic GVHD, relapse, or survival. Subcutaneous administration of alemtuzumab for GVHD prophylaxis was associated with fewer infusion-related reactions compared with i.v. administration in the SCT setting

    The combination of lenalidomide and dexamethasone is an established treatment for patients with multiple myeloma (MM). Increasingly, treatment attenuation is advocated for frail/elderly patients to minimize toxicity even though there have been no prospective studies to demonstrate whether lenalidomide dose attenuation impacts on response and survival outcome. This prospective multicentre phase II study assessed the efficacy and tolerability of lower dose lenalidomide (15 mg) and dexamethasone (20 mg) in 149 eligible patients with relapsed/refractory MM aged over 59 years and/or with renal impairment. The overall response rate was 71% (complete response 15%). Median (range) progression-free survival (PFS) and overall survival (OS) were 8·9 (6·9-11·5) and 30·5 (20·0-36·2) months, respectively. Upon formal statistical comparison of these endpoints to that of a matched cohort of patients from the pivotal phase III MM009/MM010 studies who received standard-dose lenalidomide (25 mg) and high-dose dexamethasone (40 mg) no difference was seen in PFS (P = 0·34) and OS (P = 0·21). Importantly, grade 3-4 toxicities were reduced with low-dose lenalidomide, mainly lower neutropenia (29% vs. 41%), infections (23% vs. 31%) and venous thromboembolism (3% vs. 13%). This study supports a strategy of lenalidomide dose reduction at the outset for at-risk patients, and prospectively confirms that such an approach reduces adverse events while not compromising patient response or survival outcomes.

    Isolated limb infusion (ILI) is a minimally invasive technique of delivering regional chemotherapy in patients with advanced melanoma or soft-tissue sarcoma of the limb. We report the final results of the first clinical trial of ILI in North America (NCT00004250). Eligible patients had recurrent melanoma or unresectable soft-tissue sarcoma of the limb. Angiographic catheters were positioned just above the knee or elbow of the extremity. General anesthesia was performed, a proximal tourniquet inflated, and a normothermic, low flow, hypoxic infusion of melphalan and dactinomycin circulated through the involved limb for 20 min. Tumor response and morbidity were assessed using standard criteria. Thirty-seven patients were accrued to the trial and 44 ILIs were performed (eight patients had two ILIs); one patient was not treated. Of the 32 evaluable patients, 17 (53%) had a significant response at 3 months: 25% of patients had a complete response and 28% of patients had a partial response. The median duration of complete response was 1 year (5-32 months). Morbidity was acceptable, with peak erythema, edema, and pain experienced at 2 weeks and considered 'moderate' in most patients. No patients developed compartment syndrome or required amputation because of ILI. ILI is well tolerated. More than half of the treated patients experienced a complete or partial response.

    We designed a trial using two sequential cycles of modified high-dose melphalan at 100 mg/m2 and autologous SCT (mHDM/SCT) in AL amyloidosis (light-chain amyloidosis, AL), AL with myeloma (ALM) and host-based high-risk myeloma (hM) patients through SWOG-0115. The primary objective was to evaluate OS. From 2004 to 2010, 93 eligible patients were enrolled at 17 centers in the United States (59 with AL, 9 with ALM and 25 with hM). The median OS for patients with AL and ALM was 68 months and 47 months, respectively, and has not been reached for patients with hM. The median PFS for patients with AL and ALM was 38 months and 16 months, respectively, and has not been reached for patients with hM. The treatment-related mortality (TRM) was 12% (11/ 93) and was observed only in patients with AL after SCT. Grade 3 and higher non-hematologic adverse events were experienced by 81%, 67% and 57% of patients with AL, ALM and hM, respectively, during the first and second HDM/SCT. This experience demonstrates that with careful selection of patients and use of mHDM for SCT in patients with AL, ALM and hM, even in the setting of a multicenter study, OS can be improved with acceptable TRM and morbidity.

    Treatment of primary central nervous system lymphoma (PCNSL) improved in recent years. However, the high neurotoxicity and low survival rates associated with this condition remain unresolved. We report 13 consecutive patients with PCNSL for whom upfront melphalan, cyclophosphamide, etoposide, and dexamethasone (known as LEED) followed by autologous stem-cell transplantation (ASCT) was planned at the Anjo Kosei Hospital. All patients were pathologically diagnosed with diffuse large B-cell lymphoma and were negative for human immunodeficiency virus. All patients were to receive three cycles of high-dose methotrexate-based induction chemotherapy, two cycles of high-dose AraC-based chemotherapy, and LEED followed by ASCT. All 13 patients achieved a partial response, and the 3-year overall survival (OS) rate was 76.2 %. Seven of the 13 patients were alive at the last follow-up, without any adverse events, including neurotoxicity. Six of the 13 (46.2 %) patients underwent ASCT and the 3-year OS rate was 80.0 %. Although this study included only a limited number of patients, these preliminary signs of efficacy and tolerability merit further consideration. To make further improvements in survival, the rate of patients undergoing ASCT should be increased.

    Full Text Available Randall disease is an unusual cause of extraocular motor nerve (VI palsy. A 35-year-old woman was hospitalized for sicca syndrome. The physical examination showed general weakness, weight loss, diplopia related to a left VIth nerve palsy, hypertrophy of the submandibular salivary glands, and peripheral neuropathy. The biological screening revealed renal insufficiency, serum monoclonal kappa light chain immunoglobulin, urinary monoclonal kappa light chain immunoglobulin, albuminuria, and Bence-Jones proteinuria. Bone marrow biopsy revealed medullar plasma cell infiltration. Immunofixation associated with electron microscopy analysis of the salivary glands showed deposits of kappa light chains. Randall disease was diagnosed. The patient received high-dose melphalan followed by autostem cell transplantation which led to rapid remission. Indeed, at the 2-month followup assessment, the submandibular salivary gland hypertrophy and renal insufficiency had disappeared, and the peripheral neuropathy, proteinuria, and serum monoclonal light chain had decreased significantly. The persistent diplopia was treated with nerve decompression surgery of the left extraocular motor nerve. Cranial nerve complications of Randall disease deserve to be recognized.

    Thirty-five children with high-risk leukemia received an allogeneic bone marrow transplantation (BMT) following a pre-conditioning regimen consisting of total body irradiation, thiotepa and melphalan. Twenty-one patients had acute lymphocytic leukemia, 6 acute nonlymphocytic leukemia, 2 acute undifferentiated leukemia, 2 acute mixed lineage leukemia, 2 myelodysplastic syndrome and 2 juvenile chronic myeloid leukemia. Sixteen patients received BMT while in complete remission (CR), but 19 were not in CR. Eighteen patients received transplants from HLA-matched related donors, 15 from unrelated donors and 2 from HLA-mismatched related donors. Cyclosporin{+-}methotrexate was used for graft-versus-host disease (GVHD) prophylaxis in the BMTs from related donors and tacrolimus{+-}prednisolone in the BMTs from unrelated donors. Transplant-related death occurred in 12 patients; 5 acute GVHD, 4 infections (3 fungal infections, 1 Cytomegalovirus pneumonia), 1 intracranial haemorrhage and 2 chronic GVHD. Relapses were observed in 6 patients (69, 168, 175, 222, 275 and 609 days post BMT). Event-free survival rate at 2 years is 38.1% in CR patients and 36.9% in nonCR patients. (author)

    Ploidy is an important prognostic factor in the risk stratification of multiple myeloma (MM) patients. Patients with MM can be divided into two groups according to the modal number of chromosomes: nonhyperdiploid (NH-MM) and hyperdiploid (H-MM), which has a more favorable outcome. The two ploidy groups represent two different oncogenetic pathways determined at the premalignant stage. The ploidy subtype also persists during the course of the disease, even during progression after the therapy, with only very rare cases of ploidy conversion. The clinical significance of ploidy conversion and its relation to drug resistance have been previously discussed. Here, we describe a female MM patient with a rare change in her ploidy status from H-MM to NH-MM, detected by cytogenetic and molecular cytogenetic examinations of consecutive bone marrow aspirates. We hypothesize that ploidy conversion (from H-MM to NH-MM) is associated with disease progression and acquired resistance to bortezomib/lenalidomide therapy. Copyright © 2014 Elsevier Inc.

    Detection of specific chromosomal abnormalities by FISH and metaphase cytogenetics allows risk stratification in multiple myeloma; however, gene expression profiling (GEP) based signatures may enable more specific risk categorization. We examined the utility of 2 GEP-based risk stratification systems among patients undergoing initial therapy with lenalidomide in the context of a phase 3 trial. Among 45 patients studied at baseline, 7 (16%) and 10 (22%), respectively, were high-risk using the GEP70 and GEP15 signatures. The median overall survival for the GEP70 high-risk group was 19 months versus not reached for the rest (hazard ratio = 14.1). Although the medians were not reached, the GEP15 also predicted a poor outcome among the high-risk patients. The C-statistic for the GEP70, GEP15, and FISH based risk stratification systems was 0.74, 0.7, and 0.7, respectively. Here we demonstrate the prognostic value for GEP risk stratification in a group of patients primarily treated with novel agents. This trial was registered at www.clinicaltrials.gov as #NCT00098475.

    Combinations of bortezomib (V) and dexamethasone (D) with either lenalidomide (R) or cyclophosphamide (C) have shown significant efficacy. This randomized phase 2 trial evaluated VDC, VDR, and VDCR in previously untreated multiple myeloma (MM). Patients received V 1.3 mg/m2 (days 1, 4, 8, 11) and D 40 mg (days 1, 8, 15), with either C 500 mg/m2 (days 1, 8) and R 15 mg (days 1-14; VDCR), R 25 mg (days 1-14; VDR), C 500 mg/m2 (days 1, 8; VDC) or C 500 mg/m2 (days 1, 8, 15; VDC-mod) in 3-week cycles (maximum 8 cycles), followed by maintenance with V 1.3 mg/m2 (days 1, 8, 15, 22) for four 6-week cycles (all arms)≥very good partial response was seen in 58%, 51%, 41%, and 53% (complete response rate of 25%, 24%, 22%, and 47%) of patients (VDCR, VDR, VCD, and VCD-mod, respectively); the corresponding 1-year progression-free survival was 86%, 83%, 93%, and 100%, respectively. Common adverse events included hematologic toxicities, peripheral neuropathy, fatigue, and gastrointestinal disturbances. All regimens were highly active and well tolerated in previously untreated MM, and, based on this trial, VDR and VCD-mod are preferred for clinical practice and further comparative testing. No substantial advantage was noted with VDCR over the 3-drug combinations. This trial is registered at www.clinicaltrials.gov (NCT00507442).

    Bortezomib, thalidomide and lenalidomide can be aimed at treating patients with newly diagnosed multiple myeloma (both eligible and ineligible for transplantation) as well as those with relapsed or refractory disease. This review analysed the available clinical and economic data on these three drugs. Irrespective of which of the three agents is considered, the magnitude of the benefit in newly diagnosed cases (transplanted or non-transplanted) tends to be between 10 and 20 months per patient in terms of progression-free survival or survival; the survival benefit is smaller in relapsed or refractory disease. In addition, a single-institution observational analysis evaluated the outcomes in nearly 3000 consecutive patients examined between 1971 and 2006. The survival in patients diagnosed between 2001 and 2006 was longer than that observed in patients diagnosed between 1994 and 2000. This finding supports the conclusion that novel agents provide a survival improvement compared with traditional therapy. Formal cost-effectiveness studies on these three agents are still lacking. A MEDLINE search retrieved only four short papers or letters and no full-length analysis. Hence, the cost effectiveness of these agents needs further investigation, with separate assessments of the different therapeutic settings. In a simplified analysis, we tried to contrast the average cost of treatment for each of the novel agents versus their respective benefit, expressed in quality-adjusted survival. Despite its preliminary nature, our assessment indicates that the cost effectiveness of these three agents is likely to be within commonly accepted pharmacoeconomic thresholds.

    During 1977 to 1985 90 patients with large-cell non-Hodgkin lymphoma (diffuse histiocytic or diffuse mixed according to Rapport classification) were treated by the CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone) with a mean follow-up of 41 months. Thirty-four patients were treated with radiation therapy as well. The mean number of CHOP cycles to achieve complete response was 4.0 and the mean total number of cycles was 6.6. For 78 patients it was possible to calculate relative dose intensity (RDI) for each drug and the average RDI. Sixty-four patients (71%) achieved CR. The actuarial 5-year survival rate of all patients was 52%. The median RDI for cyclophosphamide was 0.72, for doxorubicin 0.70, for vincristine 0.69 and the median average RDI was 0.69. The following favorable prognostic factors were found to be of statistical significance: female sex and stages I-III as compared to stage IV. The 5-year survival rate for stage I & II patients treated by CHOP plus radiotherapy was 70% as compared to 55% for those treated by CHOP only; this difference was not statistically significant.

    Systemic lupus erythematosus (SLE) is associated with accelerated atherosclerotic cardiovascular disease. Patients with SLE have adverse lipoprotein variables, but little is known about how these change with treatment and disease activity. The nuclear magnetic resonance LipoProfile test contains a glycoprotein signal-termed GlycA, an inflammatory marker, which has not been evaluated in SLE. We assessed patients longitudinally to determine how lipoproteins and GlycA change with active SLE. Sera from selected clinical visits of patients in the Hopkins Lupus Cohort were analyzed for lipoprotein and GlycA levels. Univariate and multivariate analyses were performed to evaluate lipoprotein variables and their relationship to ethnicity, disease activity, prednisone use, and hydroxychloroquine (HCQ) therapy. Fifty-two patients were included over 229 visits. Adverse changes in lipoprotein variables with disease activity were demonstrated. For each point increase in the Systemic Lupus Erythematosus Disease Activity Index, there was a decrease in high-density lipoprotein (HDL) even after adjusting for corticosteroid use. Prednisone was associated with higher very low-density lipoprotein, low-density lipoprotein, HDL, and triglycerides. HCQ was associated with more favorable variables. GlycA levels were higher than in normal populations and increased with disease activity. Adverse changes in lipoprotein profiles were associated with SLE activity and prednisone therapy. This gives insight into mechanisms of atherosclerosis in SLE. Favorable lipoprotein variables occurred in those taking HCQ. GlycA increased with disease activity and was higher than in healthy populations.

    Full Text Available We report the first case of multiple brain abscesses caused by Nocardia paucivorans in a patient suffering from multiple myeloma on treatment with lenalidomide and dexamethasone. Nocardia  paucivorans is a recently described species of the genus Nocardia, which is supposed to have a heightened neurotropism in cases of disseminated infection. Although nocardiosis itself is an uncommon infectious complication in multiple myeloma so far, nocardial brain abscess should be added to the spectrum of adverse effects due to this novel chemotherapy regimen.

  5. Maintenance therapy for multiple myeloma in the era of novel agents.

    Despite many recent advances in the treatment of multiple myeloma, the course of the disease is characterized by a repeating pattern of periods of remission and relapse as patients cycle through the available treatment options. Evidence is mounting that long-term maintenance therapy may help suppress residual disease after definitive therapy, prolonging remission and delaying relapse. For patients undergoing autologous stem cell transplantation (ASCT), lenalidomide maintenance therapy has been shown to improve progression-free survival (PFS); however, it is still unclear whether this translates into extended overall survival (OS). For patients ineligible for ASCT, continuous therapy with lenalidomide and low-dose dexamethasone was shown to improve PFS and OS (interim analysis) compared with a standard, fixed-duration regimen of melphalan, prednisone, and thalidomide in a large phase 3 trial. Other trials have also investigated thalidomide and bortezomib maintenance for ASCT patients, and both agents have been evaluated as continuous therapy for those who are ASCT ineligible. However, some important questions regarding the optimal regimen and duration of therapy must be answered by prospective clinical trials before maintenance therapy, and continuous therapy should be considered routine practice. This article reviews the available data on the use of maintenance or continuous therapy strategies and highlights ongoing trials that will help to further define the role of these strategies in the management of patients with newly diagnosed multiple myeloma.

    The introduction of novel agents (thalidomide, bortezomib and lenalidomide) in the frontline therapy of multiple myeloma has markedly improved the outcome both in younger patients who are candidates for high-dose therapy plus autologous stem-cell transplantation (HDT/ASCT) and in elderly patients. In the HDT/ASCT paradigm, novel agents may be used as induction therapy or after HDT/ASCT as consolidation and/or maintenance therapy. It is now possible to achieve up to 70% complete plus very good partial remission after HDT/ASCT and 70% 3-year progression-free survival (PFS). However long-term non-intensive therapy may also yield high response rates and prolonged PFS. Randomized trials comparing these two strategies are underway. In elderly patients, six randomized studies show the benefit of adding thalidomide to melphalan-prednisone (MP). a large randomized trial has also shown that the combination of bortezomib-MP is superior to MP for all parameters measuring the response and outcome. Finally, the role of maintenance is currently evaluated and a randomized trial shows that low-dose lenalidomide maintenance prolongs PFS.

    To evaluate whether blood-based genotoxicity endpoints can provide temporal and dose-response data within the low-dose carcinogenic range that could contribute to carcinogenic mode of action (MoA) assessments, we evaluated the sensitivity of flow cytometry-based micronucleus and Pig-a gene mutation assays at and below tumorigenic dose rate 50 (TD50) levels. The incidence of micronucleated reticulocytes (MN-RET) was used to evaluate chromosomal damage, and the frequency of CD59-negative reticulocytes (RET(CD59-) ) and erythrocytes (RBC(CD59-) ) served as phenotypic reporters of mutation at the X-linked Pig-a gene. Several leukemogenic agents with a presumed genotoxic MoA were studied. Specifically, male Sprague Dawley rats were treated via oral gavage for 28 days with chlorambucil, thiotepa, melphalan, and 1,3-propane sultone at doses corresponding to 0.33x, 1x, and 3x TD50, as well as at the maximum tolerated dose. Frequencies of MN-RET were determined at Days 4 and 29, and RET(CD59-) and RBC(CD59-) data were collected pretreatment as well as Days 15/16, 29, and 56/57. Dose-related increases were observed for each endpoint, and time to maximal effect was consistently: MN-RET < RET(CD59-)  < RBC(CD59-) . For each of the chemicals studied, the genotoxic events occurred long before tumors or preneoplastic lesions would be expected. Furthermore, in the case of Pig-a gene mutation, the responses were observed at or below the TD50 dose for three out of the four chemicals studied. These data illustrate the potential for quantitative blood-based analyses to provide dose-response and temporality information that relates genetic damage to cancer induction.

    Objective Fludarabine plus melphalan (FM) and fludarabine plus busulfan (FB) are two major conditioning regimens for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods We retrospectively analyzed patients who underwent allo-HSCT after a conditioning regimen consisting of FM or FB with/without total body irradiation for hematological malignancies between 2005 and 2014. Results There were 41 patients who met the criteria. The median follow-up time for the survivors was 3 years. Thirty-two patients received allo-HSCT after the FM regimen and nine patients received allo-HSCT after the FB regimen. Patients who received FB were older than those who received FM (p=0.041). There was no significant difference in the 3-year overall survival between patients who had received FB and those who had received FM (29.6% vs. 56.5%, p=0.267). The 3-year cumulative incidence of relapse was significantly higher in patients who had received FB than that in patients who had received FM (66.7% vs. 17.8%, p=0.004), and FB was an independent prognostic factor for relapse by a multivariate analysis (hazard ratio, 9.8; 95% confidential interval, 2.5-39.3; p=0.001). When we restricted the evaluation to patients with acute myeloid leukemia and myelodysplastic syndrome, the 3-year cumulative incidence of relapse was also significantly higher in patients who had received FB than that in patients who had received FM (75.0% vs. 16.1%, p=0.004). Conclusion The results suggest that FM may provide better disease control than FB.

    Fludarabine with busulfan (FB) and fludarabine with melphalan (FM) are commonly used reduced-intensity conditioning (RIC) regimens. Pharmacokinetic dosing of busulfan (Bu) is frequently done for myeloablative conditioning, but evidence for its use is limited in RIC transplants. We compared transplant outcomes of FB versus FM using i.v. Bu targeted to the area under the curve (AUC). A total of 134 RIC transplants (47 FB and 87 FM) for acute myelogenous leukemia and myelodysplastic syndrome were identified, and median follow-up of the cohort was 40 months (range, 0 to 63.3). A significantly higher 2-year cumulative incidence of relapse (CIR) was associated with FB versus FM at 35.6% versus 17.3%, respectively (P = .0058). Furthermore, 2-year progression-free survival rates were higher for FM versus FB at 60.5% versus 48.7%, respectively (P = .04). However, 2-year rates of nonrelapse mortality (NRM) and overall survival (OS) were similar. The need for dose adjustment based on AUC did not alter relapse risk or NRM. Patients with Karnofsky performance status ≥ 90 who received FM had a 2-year OS rate of 74.8% versus 48.3% for FB (P = .03). FB use remained prognostic for relapse in multivariable analysis (hazard ratio, 2.75; 95% confidence interval, 1.28 to 5.89; P = .0097). In summary, in spite of AUC-directed dosing, FB compared with FM was associated with a significantly higher CIR.

    High-dose melphalan is an important component of conditioning regimens for patients undergoing hematopoietic stem cell transplantation. The current dosing strategy based on body surface area results in a high incidence of oral mucositis and gastrointestinal and liver toxicity. Pharmacokinetically guided dosing will individualize exposure and help minimize overexposure-related toxicity. The purpose of this study was to develop a population pharmacokinetic model and optimal sampling strategy. A population pharmacokinetic model was developed with NONMEM using 98 observations collected from 15 adult patients given the standard dose of 140 or 200 mg/m(2) by intravenous infusion. The determinant-optimal sampling strategy was explored with PopED software. Individual area under the curve estimates were generated by Bayesian estimation using full and the proposed sparse sampling data. The predictive performance of the optimal sampling strategy was evaluated based on bias and precision estimates. The feasibility of the optimal sampling strategy was tested using pharmacokinetic data from five pediatric patients. A two-compartment model best described the data. The final model included body weight and creatinine clearance as predictors of clearance. The determinant-optimal sampling strategies (and windows) were identified at 0.08 (0.08-0.19), 0.61 (0.33-0.90), 2.0 (1.3-2.7), and 4.0 (3.6-4.0) h post-infusion. An excellent correlation was observed between area under the curve estimates obtained with the full and the proposed four-sample strategy (R (2) = 0.98; p strategy promises to achieve the target area under the curve as part of precision dosing.

    We report the therapeutic results of allogeneic bone marrow transplantations (BMT) for 16 children with high-risk leukemia and lymphoma. The conditioning regimen consisted of total body irradiation (TBI) (12 Gy), busulfan (Bu) (4 mg/kg x 2 days), and melphalan (L-PAM) (70 mg/m{sup 2} x 2 or 3 days). Graft-versus-host disease (GVHD) prophylaxis was performed with cyclosporin (CsA) + methotrexate (MTX) (4 cases) and CsA + MTX-methyl-prednisolone (11 cases). Seven patients had acute lymphocytic leukemia, 6 acute nonlymphocytic leukemia, 2 B-cell type non-Hodgkin`s lymphoma, and 1 peripheral T-cell lymphoma. Nine patients were in complete remission (CR) and 7 in non CR at BMT. Nine patients received transplants from HLA-matched related (MR) donors, 4 from HLA-mismatched related (MisR) donors, and 3 from unrelated (UR) donors. Seven of the cases, all of which were transplanted from MR, have continued complete remission for 15-47 (median 27) months. Nine patients, of which seven were transplanted from MisR/UR, died from complications from fungal pneumonia (3), cytomegalovirus pneumonitis (1), GVHD (1), rhabdomyolysis (1), lymphoproliferative disorder (1), rejection (1), and relapse (1). These results suggest that the combination of TBI, Bu, and L-PAM as a BMT regimen has a significant anti-neoplastic benefit and is considered to be useful; however, considering the high rate of fatal transplant-related complications, more refinement is required, especially for transplants from MisR and UR donors.

    The objective of this study was to evaluate the safety and efficacy of different lenalidomide starting doses in patients with relapsed/refractory chronic lymphocytic leukemia (CLL). CLL patients were randomized to receive lenalidomide at initial doses of 5, 10, or 15 mg/d (N = 103). Doses were escalated by 5 mg every 28-d up to a maximum of 25 mg/d; dose reductions in up to 5 mg decrements were permitted. The most common grade ≥3 adverse events (AEs) were neutropenia and thrombocytopenia. Ten patients died during therapy (four deaths considered as related to lenalidomide); 12 patients experienced second primary malignancies. The most common cause for treatment discontinuation was AEs. Overall response rates were similar across arms. Progression-free survival and overall survival rates were longer in patients who escalated treatment (to 15 or 20 mg/d) versus those who did not. Lower starting doses allowed subsequent dose escalation of lenalidomide while maintaining an acceptable tolerability profile in patients with relapsed/refractory CLL.

    A simple, rapid and stability-indicating chiral HPLC (CHR-HPLC) method was designed for the enantiomeric separation of lenalidomide (LDM) in the presence of its degradation products. LDM was exposed to different accelerated stress factors. The degradation products were well resolved from the pure drug enantiomers. Separation of the LDM enantiomers was achieved on a LUX 5U cellulose-2 chiral column (250 × 4.6 mm i.d.) with a mobile phase consisting of methanol : glacial acetic acid : triethyl amine (100 : 0.01 : 0.01, v/v/v) at a flow rate of 1.2 mL/min. The detection wavelength was 220 nm, and ornidazole was the internal standard. The chiral method was validated in terms of its specificity, linearity, range, precision and accuracy as well as solution stability, robustness, limit of detection and limit of quantification. The calibration curve was linear for concentrations ranging from 2 to 1,000 ng/mL (r = 0.9999) for both LDM enantiomers. The proposed method, which met International Conference on Harmonization/Food and Drug Administration regulatory requirements, was utilized successfully for the determination of LDM in bulk and in capsules with acceptable accuracy and precision; the label demand percentages were 100.09 ± 0.80 and 99.97 ± 0.93 for the S-(−) and R-(+)-LDM enantiomers, respectively. Based on these results, this method should have great value when applied to quality control and stability studies of LDM. PMID:26850732

    Full Text Available Abstract Background Lenalidomide (LND is a potent novel thalidomide analog which demonstrated remarkable clinical activity in treatment of multiple myeloma disease via a multiple-pathways mechanism. The strong evidences-based clinical success of LND in patients has led to its recent approval by US-FDA under the trade name of Revlimid® capsules by Celgene Corporation. Fluorimetry is a convenient technique for pharmaceutical quality control, however there was a fluorimetric method for determination of LND in its bulk and capsules. Results A novel highly sensitive and simple fluorimetric method has been developed and validated for the determination of lenalidmide (LND in its bulk and dosage forms (capsules. The method was based on nucleophilic substitution reaction of LND with fluorescamine (FLC in aqueous medium to form a highly fluorescent derivative that was measured at 494 nm after excitation at 381 nm. The factors affecting the reaction were carefully studied and optimized. The kinetics of the reaction was investigated, and the reaction mechanism was postulated. Under the optimized conditions, linear relationship with good correlation coefficient (0.9999 was found between the fluorescence intensity and LND concentration in the range of 25–300 ng/mL. The limits of detection and quantitation for the method were 2.9 and 8.7 ng/mL, respectively. The precision of the method was satisfactory; the values of relative standard deviations did not exceed 1.4%. The proposed method was successfully applied to the determination of LND in its bulk form and pharmaceutical capsules with good accuracy; the recovery values were 97.8–101.4 ± 1.08–2.75%. Conclusions The proposed method is selective and involved simple procedures. In conclusion, the method is practical and valuable for routine application in quality control laboratories for determination of LND.

    Full Text Available Abstract Background While lenalidomide (LEN shows high efficacy in myelodysplastic syndromes (MDS with del[5q], responses can be also seen in patients presenting without del[5q]. We hypothesized that improved detection of chromosomal abnormalities with new karyotyping tools may better predict response to LEN. Design and methods We have studied clinical, molecular and cytogenetic features of 42 patients with MDS, myeloproliferative neoplasms (MPN, MDS/MPN overlap syndromes and secondary acute myeloid leukemia (sAML without del[5q] by metaphase cytogenetics (MC who underwent therapy with LEN. Results Fluorescence in situ hybridization (FISH or single nucleotide polymorphism array (SNP-A-based karyotyping marginally increased the diagnostic yield over MC, detecting 2/42 (4.8% additional cases with del[5q], one of whom were responded to LEN. Responses were more often observed in patients with a normal karyotype by MC (60% vs abnormal MC; 17%, p = .08 and those with gain of chromosome 8 material by either of all 3 karyotyping methods (83% vs all other chromosomal abnormalities; 44% p = .11. However, 5 out of those 6 patients received combined LEN/AZA therapy and it may also suggest those with gain of chromosome 8 material respond well to AZA. The addition of FISH or SNP-A did not improve the predictive value of normal cytogenetics by MC. Mutational analysis of TET2, UTX, CBL, EZH2, ASXL1, TP53, RAS, IDH1/2, and DNMT-3A was performed on 21 of 41 patients, and revealed 13 mutations in 11 patients, but did not show any molecular markers of responsiveness to LEN. Conclusions Normal karyotype and gain of chromosome 8 material was predictive of response to LEN in non-del[5q] patients with myeloid malignancies.

    Membranous nephropathy is a common cause of the nephrotic syndrome. Treatment with standard regimens fails to induce complete remission in most patients. We evaluated the efficacy of combination therapy with rituximab, low-dose, oral cyclophosphamide, and an accelerated prednisone taper (RCP) for the treatment of idiopathic membranous nephropathy. We analyzed 15 consecutive patients with idiopathic membranous nephropathy treated with RCP at Massachusetts General Hospital. Seven patients (47%) received RCP as initial therapy, and the other eight patients (53%) received RCP for relapsing or refractory disease. All patients had at least 1 year of follow-up. The co-primary outcomes were attainment of partial and complete remission. Partial remission was defined as a urinary protein to creatinine ratio (UPCR) < 3 g/g and a 50% reduction from baseline. Complete remission was defined as a UPCR < 0.3 g/g. Secondary outcomes were serious adverse events and the change in proteinuria, serum creatinine, serum albumin, cholesterol, triglycerides, and immunoglobulin G levels after 1 year of treatment. Over a median follow-up time of 37 (IQR, 34-44) months, 100% of patients achieved partial remission and 93% of patients achieved complete remission at a median time of 2 and 13 months, respectively. After 1 year of treatment, median (IQR) UPCR declined from 8.2 (6.6-11.1) to 0.3 (0.2-0.7) g/g (P < 0.001). Three serious adverse events occurred over 51 patient years. No patients died or progressed to ESKD. Treatment of idiopathic membranous nephropathy with RCP resulted in high rates of complete remission. Larger studies evaluating this regimen are warranted.

    In patients with low and intermediate risk myelodysplastic syndrome and deletion 5q (del(5q)) treated with lenalidomide, monitoring of cytogenetic response is mandatory, since patients without cytogenetic response have a significantly increased risk of progression. Therefore, we have reviewed cytogenetic data of 302 patients. Patients were analyzed by karyotyping and fluorescence in situ hybridization. In 85 patients, del(5q) was only detected by karyotyping. In 8 patients undergoing karyotypic evolution, the del(5q) and additional chromosomal aberrations were only detected by karyotyping. In 3 patients, del(5q) was only detected by fluorescence in situ hybridization, but not by karyotyping due to a low number of metaphases. Karyotyping was significantly more sensitive than fluorescence in situ hybridization in detecting the del(5q) clone. In conclusion, to optimize therapy control of myelodysplastic syndrome patients with del(5q) treated with lenalidomide and to identify cytogenetic non-response or progression as early as possible, fluorescence in situ hybridization alone is inadequate for evaluation. Karyotyping must be performed to optimally evaluate response. (clinicaltrials.gov identifier: NCT01099267 and NCT00179621) PMID:21109690

    The combination of lenalidomide (Revlimid(®) , R) and dexamethasone (d) is a standard regimen for patients with relapsed/refractory multiple myeloma (rrMM). With this regimen, only a small fraction of patients will achieve high quality responses [≥ very good partial response (VGPR)]. The combination of bendamustine (B), lenalidomide and dexamethasone (BRd) has shown high efficacy in patients with advanced rrMM. However, dose-limiting haematotoxicity restricted its use in extensively pre-treated patient populations. This prospective, multicentre Phase II study evaluated the efficacy and safety of BRd in rrMM patients with one prior line of therapy. Fifty patients were enrolled (median age 68·5 years [range 46-83]) and were treated with B 75 mg/m(2)  days 1, 2; R 25 mg days 1-21 and d (40/20 mg) days 1, 8, 15 and 22, for 6 28-day induction cycles, followed by 12 cycles with Rd alone. Pegfilgrastim was administered according to protocol-defined criteria. The study aimed to demonstrate a complete response (CR)/VGPR rate of >40% after induction therapy. Of 45 evaluable patients, 23 (51%) achieved a CR/VGPR. Grade 4 neutropenia or thrombocytopenia occurred in 17 (34%) and 8 (16%) of patients, respectively. BRd is a safe and efficacious regimen as a second line treatment for rrMM, leading to high quality responses in a considerable proportion of patients.

    Aneuploidy is a very common prognostic factor in multiple myeloma (MM). Nonhyperdiploidy including near-tetraploidy (NT) is a poor prognostic indicator, compared to hyperdiploidy in multiple myeloma (MM). NT results from endoduplication of hypodiploidy. We report of a 55-year-old female patient diagnosed with advanced stage MM with hyperdiploidy and t(8;14)(q24;q32). The patient responded well to lenalidomide and dexamethasone for approximately 1 year. At the time of progression, she had become unresponsive to lenalidomide and subsequently bortezomib, and was found to have NT and loss of choromosome 13. There is another reported patient who had a possible interchange from nonhyperdiploidy to hyperdiploidy status, however, artifact could not be ruled out. To our knowledge, this is the first patient in whom evolution of an abnormal clone from a hyperdiploidy to a NT abnormal clone has been confirmed during the natural course of MM. This evolution is associated with resistance to novel drugs and poor prognosis in MM.

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer of lenalidomide (Celgene) to submit evidence of the clinical and cost effectiveness of the drug for treating adults with myelodysplastic syndromes (MDS) associated with deletion 5q cytogenetic abnormality, as part of the Institute's single technology appraisal (STA) process. Kleijnen Systematic Reviews Ltd (KSR), in collaboration with Erasmus University Rotterdam, was commissioned to act as the Evidence Review Group (ERG). This paper describes the company's submission, the ERG review, and the NICE's subsequent decisions. The ERG reviewed the evidence for clinical and cost effectiveness of the technology, as submitted by the manufacturer to the NICE. The ERG searched for relevant additional evidence and validated the manufacturer's decision analytic model to examine the robustness of the cost-effectiveness results. Clinical effectiveness was obtained from a three-arm, European, randomized, phase III trial among red blood cell (RBC) transfusion-dependent patients with low-/intermediate-1-risk del5q31 MDS. The primary endpoint was RBC independence for ≥26 weeks, and was reached by a higher proportion of patients in the lenalidomide 10 and 5 mg groups compared with placebo (56.1 and 42.6 vs 5.9 %, respectively; both p < 0.001). The option of dose adjustments after 16 weeks due to dose-limiting toxicities or lack of response made long-term effectiveness estimates unreliable, e.g. overall survival (OS). The de novo model of the manufacturer included a Markov state-transition cost-utility model implemented in Microsoft Excel. The base-case incremental cost-effectiveness ratio (ICER) of the manufacturer was £56,965. The ERG assessment indicated that the modeling structure represented the course of the disease; however, a few errors were identified and some of the input parameters were challenged. In response to the appraisal documentation, the company revised the economic model

    Full Text Available Multiple myeloma (MM is a neoplastic lymphoproliferative disorder characterized by uncontrolled monoclonal plasma cell proliferation. Among different isotypes of MM, immunoglobulin D (IgD MM is very rare, representing only 1 to 2% of all isotypes. Chronic myelogenous leukemia (CML is a neoplastic myeloproliferative disorder of pluripotent hematopoietic stem cell, which is characterized by the uncontrolled proliferation of myeloid cells. An 88-year-old male was diagnosed simultaneously with IgD kappa MM and CML. A distinctive feature in this patient was the progression to plasma cell leukemia without any symptomatic myeloma stage. He was treated simultaneously with lenalidomide, bortezomib and imatinib. Synchronous occurrence of these rare hematological malignancies in a single patient is an exceedingly rare event. Multiple hypotheses to explain co-occurrence of CML and MM have been proposed; however, the exact etiological molecular pathophysiology remains elusive.

    Full Text Available Abstract Background Lenalidomide (LND is a potent novel thalidomide analog which demonstrated remarkable clinical activity in treatment of multiple myeloma disease via a multiple-pathways mechanism. Validated sensitive method with high throughput is required for the determination of lenalidomide for pharmacokinetics and toxicokinetic studies. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS is a preeminent analytical tool for rapid biomedical analysis. Results A simple, highly sensitive UPLC-MS/MS method was developed and validated for the determination of LND in rabbit and human plasma. After a simple protein precipitation using methanol, LND and carbamazepine (IS were separated on Acquity UPLC BEH™ C18 column (50 × 2.1 mm, i.d. 1.7 μm, Waters, USA using a mobile phase consisted of acetonitrile:water:formic acid (65:35:0.1%, v/v/v pumped at a flow rate of 0.2 mL/min. LND and IS were eluted at 0.71 and 1.92 min, respectively. The mass spectrometric determination was carried out using an electrospray interface operated in the positive mode with multiple reaction monitoring (MRM mode. The precursor to product ion transitions of m/z 260.1 > 149.0 and m/z 237.0 > 179.0 were used to quantify LND and IS, respectively. The method was linear in the concentration range of 0.23–1000 ng/mL with a limit of quantitation of 0.23 ng/mL. All the validation parameters were in the ranges acceptable by the guidelines of analytical method validation. Conclusion The proposed UPLC-MS/MS method is simple, rapid and highly sensitive, and hence it could be reliable for pharmacokinetic and toxicokinetic study in both animals and humans.

    Full Text Available Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T is a hematologic malignancy that often results in transfusion dependency and a hypercoagulable state. This rare disease currently lacks formal guidelines for treatment; however, various case reports have demonstrated efficacy in the use of lenalidomide. This immunomodulatory drug has shown promise in patients with 5q deletions, with reports of achieving transfusion independence and normalization of platelet counts. Herein we present the case of a 68-year-old African American woman with RARS-T who tested negative for 5q deletion and JAK2 V617F and MPL W515K/L mutations. Her treatment with lenalidomide therapy resulted in a five-year durable complete clinical response.

    This multicenter phase 1/2 trial investigated the combination of bendamustine, lenalidomide, and dexamethasone in repeating 4-week cycles as treatment for relapsed refractory multiple myeloma (MM). Phase 1 established maximum tolerated dose (MTD). Phase 2 assessed overall response rate at the MTD. Secondary endpoints included progression-free survival (PFS) and overall survival (OS). A total of 29 evaluable patients were enrolled. Median age was 63 years (range, 38-80 years). Median number of prior therapies was 3 (range, 1-6). MTD was bendamustine 75 mg/m2 (days 1 and 2), lenalidomide 10 mg (days 1-21), and dexamethasone 40 mg (weekly) of a 28-day cycle. Partial response rate was 52%, with very good partial response achieved in 24%, and minimal response in an additional 24% of patients. Median follow-up was 13 months; median OS has not been reached. One-year OS is 93% (95% confidence interval [CI], 59%-99%). Median PFS is 6.1 months (95% CI, 3.7-9.4 months) with one-year PFS of 20% (95% CI, 6%-41%). Grade 3/4 adverse events included neutropenia, thrombocytopenia, anemia, hyperglycemia, and fatigue. This first phase 1/2 trial testing bendamustine, lenalidomide, and dexamethasone as treatment of relapsed refractory MM was feasible and highly active.

    Recent discoveries suggest that the critical events leading to the anti-proliferative activity of the IMiD immunomodulatory agents lenalidomide and pomalidomide in multiple myeloma (MM) cells are initiated by Cereblon-dependent ubiquitination and proteasomal degradation of substrate proteins Ikaros (IKZF1) and Aiolos (IKZF3). By performing kinetic analyses, we found that the downregulation or proteasomal degradation of Ikaros and Aiolos led to specific and sequential downregulation of c-Myc followed by IRF4 and subsequent growth inhibition and apoptosis. Notably, to ensure growth inhibition and cell death, sustained downregulation of Ikaros and Aiolos, c-Myc or IRF4 expression was required. In addition, we found that the half-maximal rate, rather than the final extent of Ikaros and Aiolos degradation, correlated to the relative efficacy of growth inhibition by lenalidomide or pomalidomide. Finally, we observed that all four transcription factors were elevated in primary MM samples compared with normal plasma cells. Taken together, our results suggest a functional link between Ikaros and Aiolos, and the pathological dysregulation of c-Myc and IRF4, and provide a new mechanistic understanding of the relative efficacy of lenalidomide and pomalidomide based on the kinetics of substrate degradation and downregulation of their downstream targets.

Finally, we observed that all four transcription factors were elevated in primary MM samples compared with normal plasma cells. Taken together, our results suggest a functional link between Ikaros and Aiolos, and the pathological dysregulation of c-Myc and IRF4, and provide a new mechanistic understanding of the relative efficacy of lenalidomide and pomalidomide based on the kinetics of substrate degradation and downregulation of their downstream targets.

    Objective:To explore the effect of Ginkgo biloba extract (EGb) in combined with prednisone on the arterial blood gas and pulmonary function in patients with idiopathic pulmonary fibrosis (IPF).Methods: A total of 76 patients with IPF who were admitted in our hospital from March, 2015 to March, 2016 were included in the study and randomized into the observation group and the control group. The patients in the two groups were given oxygen inhalation, bronchodilator agents, phlegm dissipating and asthma relieving, anti-infection, and other supporting treatments. The patients in the control group were orally given prednisone (0.5 mg/kg.d), continuously for 4 weeks, then in a dose of 0.25 mg/kg.d, continuously for 8 weeks, and finally the dosage was reduced to 0.125 mg/kg.d. On this basis, the patients in the observation group were given additional EGb, i.e. Ginkgo leaf capsule, 1 g/time, 3 times/d, continuously for 12 weeks. The efficacy was evaluated after 12-week treatment. PaO2, PaCO2, P(A-a)O2, and SaO2 before and after treatment were detected. FVC, FEV1/FVC, MVV, TLC, and DLCO before and after treatment were determined.Results: PaO2, PaCO2, and SaO2 after treatment were significantly elevated, while P(A-a)O2 was significantly reduced when compared with before treatment. The comparison of PaO2 and P(A-a)O2 between the two groups was statistically significant, while the comparison of PaCO2 and SaO2 between the two groups was not statistically significant. After treatment, FVC, FEV1/FVC, MVV, TLC, and DLCO in the two groups were significantly elevated when compared with before treatment, and those in the observation group were significantly superior to those in the control group.Conclusions:EGb in combined with prednisone in the treatment of IPF can effectively improve the arterial blood gas indicators and pulmonary function, and enhance the patients’ living qualities; therefore, it deserves to be widely recommended.

    172 patients who had had mastectomy for breast cancer were treated by repeated adjuvant chemotherapy, either with phenylalanine mustard (P.A.M.) or a combination of cyclophosphamide, 5-fluorouracil, and prednisone (C.F.P.) with and without radiotherapy. Tumours recurred significantly more frequently and mortality tended to be higher in P.A.M.-treated patients than in patients on other treatment. The interval between surgery and disease recurrence was significantly shorter for P.A.M.-treated premenopausal but not postmenopausal patients than for patients of equivalent menstrual status treated with C.F.P. with or without radiation. The associations in premenopausal patients between the mode of treatment and both survival and the disease-free interval were significant before and after adjustment for variations between the treatment groups in the number of involved lymph nodes and the size of the primary tumour.

    Ninety patients with advanced breast cancer received a polychemotherapeutic program composed of 5-fluorouracil, cyclophosphamide, and prednisone with or without vincristine as a control group in a series of four consecutive Phase II clinical trials of new drug programs. Objective regression rates were 59% without vincristine and 46% with vincristine. Projected mean length of regressions exceeds 1 year. Site of dominant disease, disease-free interval, or performance scale score (if score was 0, 1, or 2, ECOG scale) failed to influence response rates; decreasing response rates were noted as the length of time increased after menopause. No advantage existed in patients experiencing severe myelosuppression (nadir leukocyte count of less than 1,500/mm), and appreciable response rates occurred without significant myelosuppression. The addition of vincristine to the regimen failed to increase the response rates, and only increased toxicity. The program as outlined is reasonably tolerable and effective for this group of patients with advanced breast cancer.

    Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin's lymphoma. Bortezomib is the first product to be approved for the treatment of patients with previously untreated MCL, for whom haematopoietic stem cell transplantation is unsuitable, and is used in combination with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (VR-CAP). The National Institute of Health and Care Excellence recently recommended the use of VR-CAP in the UK following a technology appraisal. We present the cost effectiveness analysis performed as part of that assessment: VR-CAP versus the current standard of care regimen of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in a UK setting. A lifetime economic model was developed with health states based upon line of treatment and progression status. Baseline patient characteristics, dosing, safety and efficacy were based on the LYM-3002 trial. As overall survival data were immature, survival was modelled by progression status, and post-progression survival was assumed equal across arms. Utilities were derived from LYM-3002 and literature, and standard UK cost sources were used. Treatment with VR-CAP compared to R-CHOP gave an incremental quality-adjusted life year (QALY) gain of 0.81 at an additional cost of £16,212, resulting in a base case incremental cost-effectiveness ratio of £20,043. Deterministic and probabilistic sensitivity analyses showed that treatment with VR-CAP was cost effective at conventional willingness-to-pay thresholds (£20,000-£30,000 per QALY). VR-CAP is a cost-effective option for previously untreated patients with MCL in the UK.

    Bendamustine is a bifunctional alkylating agent with proven activity in myeloma. In this study 60 newly diagnosed myeloma patients were given bendamustine plus bortezomib and prednisone in a regimen consisting of one cycle of bortezomib twice weekly for 6 weeks (1.3 mg/m2 on days 1, 4, 8, 11, 22, 25, 29, and 32), plus bendamustine (90 mg/m2 on days 1 and 4) and prednisone. The following cycles included bortezomib once weekly. Patients who were transplant candidates proceeded to stem cell collection after four cycles and the transplant was performed after six cycles. Patients who were not candidates for transplantation received up to nine cycles. Forty-two patients were transplant candidates and after six cycles, 50% achieved at least a very good partial response, with 24% having complete responses; 35 proceeded to a transplant, and the complete response rate was 54%. Seventeen patients continued up to nine cycles, and 57% achieved at least a very good partial response, including 26% with complete responses. The 2-year progression-free survival and overall survival rates were 62% and 86%, respectively. The safety profile was manageable, but stem cell mobilization was compromised in 35% of patients. In summary, this combination is effective in untreated patients, with an acceptable toxicity profile, but given the introduction of second-generation novel agents and monoclonal antibodies, the combination will probably be better reserved for relapsing patients, in whom stem cell collection is not needed, while cost-effective combinations with non-cross-resistant drugs continue to represent a medical need. This trial was registered with ClinicalTrials.gov, number NCT01376401. PMID:25911554

    One hundred ninety-eight children and adolescents were entered in the Associazione Italiana di Ematologia ed Oncologia Pediatrica (AIEOP)-ALL95 study for high-risk acute lymphoblastic leukemia (ALL). Inclusion criteria were poor response to initial prednisone/intrathecal methotrexate (prednisone-poor response [PPR]), resistance to induction therapy, translocation t(9;22), infants with the t(4;11), or CD10(-) ALL. The event-free survival (EFS) rate at 4 years was 56.5% (SE, 3.9%) for the entire group. The overall EFS rate in the current study was significantly better (P =.002) than that obtained in a comparable group of patients treated in the early 1990s in the AIEOP-ALL91 study. In particular, patients with PPR had a 4-year EFS of 61.1% (SE, 4.4%) versus 42.8% (SE, 5.4%) in the ALL 91 study (P =.008). Among PPR patients, those who were PPR-only (60.1%)-that is, they achieved CR and were negative for t(9;22) and t(4;11) translocations-had the best outcomes with this intensive treatment, even when additional adverse features (hyperleukocytosis, T phenotype) were present (4-year EFS, 70.1%; SE, 4.7%). We attribute this improvement to the replacement of 6 alternating blocks of non-cross-resistant drugs with an 8-drug reinduction regimen (Berlin-Frankfurt-Muenster [BFM] protocol II), repeated twice, in the context of a standard BFM-type intensive chemotherapy for high-risk ALL. This modified therapy may lead to high cure rates for patients defined as at high risk for intrinsic resistance to corticosteroids only.

    Full Text Available Abstract Background Lenalidomide treatment in myelodysplastic syndrome (MDS may lead to thrombocytopenia and dose reductions/delays. This study evaluated the safety and tolerability of the thrombopoietin mimetic romiplostim and its effects on the incidence of clinically significant thrombocytopenic events (CSTEs in lower risk MDS patients receiving lenalidomide. Methods Patients were assigned to weekly placebo (n = 12 or romiplostim 500 μg (n = 14 or 750 μg (n = 13 for four 28-day lenalidomide cycles. Results The treatment groups were generally similar with respect to baseline disease characteristics. Del(5q abnormalities were noted in 1 (8% patient in the placebo group, 3 (21% in the romiplostim 500 μg group, and two (15% in the 750 μg group. CSTEs were noted in 8 (67% patients in the placebo group, 4 (29% in the romiplostim 500 μg group, and 8 (62% in the romiplostim 750 μg group. Throughout the study, median platelet counts trended lower in placebo-treated than in romiplostim-treated patients. Thrombocytopenia-related adjustments in lenalidomide occurred in 6 (50% patients in the placebo group, 5 (36% in the romiplostim 500 μg group, and 2 (15% in the 750 μg group. Although the percentages of patients who received platelet transfusions were similar across treatment groups, there was a trend toward lower numbers of transfusions in both romiplostim groups during each treatment cycle. There were two serious treatment-related adverse events during the treatment period (cerebrovascular accident, placebo; worsening thrombocytopenia, romiplostim 500 μg. Two patients (romiplostim 500 and 750 μg, respectively had an increase in bone marrow blasts to >20% during treatment, but had no post-treatment biopsy to confirm or exclude the diagnosis of progression to AML. Conclusions These data suggest that romiplostim administered to MDS patients during lenalidomide treatment may decrease the frequency of dose

    The aim of the present study was to investigate the mechanisms underlying the effects of prednisone on adriamycin-induced nephritic rat kidney damage via the focal adhesion kinase (FAK)/receptor activator of nuclear factor-κB ligand (RANKL)/mitogen‑activated protein kinase (MAPK) signaling pathway. An adriamycin‑induced nephritic rat model was established to investigate these mechanisms. A total of 30 healthy male Sprague‑Dawley rats were randomly assigned to the normal, model or prednisone group. Samples of urine were collected over the course of 24 h at days 7, 14, and 28, and renal cortex tissue samples were harvested at days 14, and 28 following nephritic rat model establishment. The total urinary protein content was measured by biuret colorimetry. Pathological changes in the kidney tissue samples were observed using an electron microscope. The mRNA expressions levels of FAK, RANKL, p38, extracellular signal‑regulated kinase (ERK), c‑Jun N‑terminal kinase (JNK), and nephrin were then quantified by reverse transcription‑quantitative polymerase chain reaction. In addition, the protein expressions levels of FAK, RANKL, p38, ERK, JNK, phosphorylated (p)‑FAK, p‑ERK, and p‑JNK were quantified by western blotting. As compared with the normal group, the protein expression levels of FAK, RANKL, p-FAK, p38 and p-ERK in the model group were increased. In the prednisone group, the protein expression levels of p-ERK decreased, as compared with the normal group. In the prednisone group, the urinary protein levels, the protein expression levels of FAK, RANKL, p38, p-FAK, p-p38 and the mRNA expression levels of FAK, p38, RANKL, ERK, JNK decreased, as compared with the model group. In the prednisone group, the mRNA and protein expression levels of nephrin and the serum expression levels of RANKL increased, the serum expression levels of osteoprotegerin (OPG) were decreased, as compared with the model group. No significant changes in the protein expression

    Abstract Background: Simultaneous multiple myeloma (MM) and pulmonary adenocarcinoma is a rare occurrence, and thus, treatment is a challenge. This study reports on 1 such case of MM with concurrent lung cancer, where an accurate diagnosis was made and the patient underwent treatment for both cancers. Case summary: A 68-year-old man presented with 2 months of progressive lower back pain. Visualization with magnetic resonance imaging (MRI) revealed multiple collapsed vertebrae from T12 to S3, as well as an altered signal intensity at the T3 vertebra. The patient was diagnosed with MM upon examination. A chest computed tomography (CT) scan revealed a round mass in the left lower lobe of the lungs, and a CT-guided needle biopsy uncovered a moderately differentiated adenocarcinoma. There were no additional notable findings in the left lung using positron emission tomography computed tomography (PET-CT). Therefore, a diagnosis of MM with pulmonary adenocarcinoma was made. Surgery was performed to excise the lung cancer. Bortezomib was used as first-line induction therapy against both tumors and lenalidomide was used for maintenance. The patient went into complete remission. Using this combined chemotherapy, the patient has survived for over 3 years since a diagnosis was made despite relapsing twice after the first year. Conclusion: This report clearly delineates the diagnosis and treatment of a rare case of synchronous MM and pulmonary adenocarcinoma, as well as depicts a potentially positive outcome for the patient. It also overviews some diagnostic and therapeutic implications for clinicians. PMID:28072730

    Takeshi Harada

    Full Text Available The immunomodulatory drug lenalidomide (Len has drawn attention to potentiate antibody-dependent cellular cytotoxicity (ADCC-mediated immunotherapies. We developed the defucosylated version (YB-AHM of humanized monoclonal antibody against HM1.24 (CD317 overexpressed in multiple myeloma (MM cells. In this study, we evaluated ADCC by YB-AHM and Len in combination against MM cells and their progenitors. YB-AHM was able to selectively kill via ADCC MM cells in bone marrow samples from patients with MM with low effector/target ratios, which was further enhanced by treatment with Len. Interestingly, Len also up-regulated HM1.24 expression on MM cells in an effector-dependent manner. HM1.24 was found to be highly expressed in a drug-resistant clonogenic "side population" in MM cells; and this combinatory treatment successfully reduced SP fractions in RPMI 8226 and KMS-11 cells in the presence of effector cells, and suppressed a clonogenic potential of MM cells in colony-forming assays. Collectively, the present study suggests that YB-AHM and Len in combination may become an effective therapeutic strategy in MM, warranting further study to target drug-resistant MM clonogenic cells.

    Full Text Available We report a case of facial diffuse large B-cell lymphoma (DLBCL associated with recurrent metastasis in the heart and other sites in a 76-year-old Japanese woman. Initially, she developed DLBCL in her left upper eyelid that spread into the left orbit (Ann Arbor classification stage I. The lesion went into clinical regression after 4 cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy followed by radiotherapy. More than 3 years later, the lymphoma recurred in her facial skin, together with metastases in the mediastinal lymph nodes and the heart; the tumor in the heart was successfully detected by PET/CT and cardiac MRI. To treat the recurrent lesions, we performed a salvage chemotherapy regimen comprising prednisone, etoposide, procarbazine, and cyclophosphamide, which successfully induced tumor regression.

    The administration of boldenone and androstadienedione to cattle is forbidden in the European Union, while prednisolone is permitted for therapeutic purposes. They are pseudoendogenous substances (endogenously produced under certain circumstances). The commonly used matrices in control analyses are urine or liver. With the aim of improving the residue controls, we previously validated a method for steroid analysis in bile. We now compare urine (a 'classic' matrix) to bile, both collected at the slaughterhouse, to understand whether the detection of steroids in the latter is easier. With the aim of having clearer results, we tested the presence of the synthetic corticosteroid dexamethasone. The results show that bile does not substantially improve the detection of boldenone, or its conjugates, prednisolone and prednisone. Dexamethasone, instead, was found in 10 out of 53 bovine bile samples, but only in one urine sample from the same animals. Bile could constitute a novel matrix for the analysis of residues in food-producing animals, and possibly not only of synthetic corticosteroids. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Primary malignant lymphoma of the uterine cervix is a rare disease, and the therapeutic strategy has not been clearly established. A 45-year old woman presented with vaginal bleeding and hypermenorrhea in January 2012. Physical examination revealed a mass in the pelvic cavity approximately the size of a neonate's head. Pelvic magnetic resonance imaging(MRI) showed a solid mass 11 cm in size in the uterine cervix with homogeneous low intensity on T1-weighted images, iso-high intensity on T2-weighted images, and heterogeneous iso-high intensity on gadolinium-diethylenetriaminepentaacetate(Gd- DTPA)-enhanced images. Multiple lymphadenopathy were also detected in the pelvis. The Papanicolaou smear indicated class 5 cervical cytology, and a subsequent histological examination by a punch biopsy of the cervix showed diffuse infiltration of medium- to large-sized mononuclear cells that stained positive for CD20 and CD79a and negative for CD3, CD5, and EBER. Bone marrow biopsy revealed no abnormality. Positron emission tomography-computed tomography(PET-CT)showed strong fluorodeoxyglucose(FDG)accumulation in the uterine cervix mass, and in the pelvic and right inguinal lymphadenopathy. The patient was diagnosed with diffuse large B-cell lymphoma of the uterine cervix, Ann Arbor stage II AE. She was successfully treated with 8 courses of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone(R-CHOP) chemotherapy, and maintains a complete remission.

    Although melphalan at a dose of 140 mg/m(2) (MEL140) is an acceptable conditioning regimen for autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients, very few studies compared it to the most commonly used dose of 200 mg/m(2) (MEL200). A retrospective review of records of MM patients (2001-2010) identified 33 patients who received MEL140 and 96 patients who received MEL200. As expected, significantly higher percentage of patients in the MEL140 arm were >65 years or had cardiac ejection fraction 2 at the time of ASCT (P≤.01). There were no significant differences in incidence of treatment related mortality and morbidity. At a median follow-up of 74 months from ASCT, there were no significant differences in relapse free survival (RFS) and overall survival (OS) between the two groups. Similar proportion had myeloma status improve to ≥VGPR at 3 months post-ASCT. Usage of post-ASCT maintenance was similar. In multivariate cox proportional hazards model, only disease status of ≥VGPR at the time of ASCT significantly improved RFS (P=.024), but not OS (P=.104). In conclusion, MM patients who received MEL140 had similar long-term outcomes to MEL200 patients despite their older age and co-morbidities. © 2016 John Wiley & Sons A/S.

    Abstract Allogeneic transplant using reduced intensity conditioning is a therapeutic option for patients with Hodgkin lymphoma (HL) who relapse after an autograft. This was a prospective study of 31 consecutive eligible patients with HL who relapsed after an autograft and underwent an allograft using BEAM (BCNU, etoposide, cytarabine, melphalan) conditioning. At a median follow-up of 7 years the progression-free survival (PFS) was 36% (95% confidence interval [CI] 19-54%) and overall survival (OS) was 42% (95% CI 23-59%). In multivariate analysis only residual disease at the time of transplant predicted outcome, with a 4-year PFS and OS of 62% and 75% for patients with minimal residual disease versus 8% and 8% for patients with gross residual disease, respectively (p = 0.005 and p = 0.001, respectively). This benefit seemed to be irrespective of chemosensitivity, with an OS for patients with chemorefractory yet minimal disease of 71% at 4 years. BEAM allogeneic transplant is effective in producing long-term remissions after autograft failure. Regardless of chemosensitivity, minimizing tumor burden pre-transplant may improve long-term outcome.

    Changes in beta 2-adrenoceptor function by chronic dosing of beta 2-mimetics and the possible influence of a single dose of prednisone have been studied as changes over time in the concentration-effect relationship of the beta 2-adrenoceptor agonist terbutaline. Hypokalaemia was used as the specific beta 2-adrenoceptor mediated effect. 8 healthy volunteers were given subcutaneous terbutaline 0.01 mg.kg-1 BW on 3 occasions over a 10-day experimental protocol: 1 Control experiment on Day 1; 2 After 7 days of oral terbutaline 5 mg t.i.d. (Day 8); and 3 After 8 days on oral terbutaline and 12 h after prednisone 100 mg orally (Day 10). The time course of the terbutaline concentrations and hypokalaemia was related using a pharmacokinetic-pharmacodynamic model. A sigmoid and a threshold Emax model were used to relate drug concentrations to effects. The oral terbutaline treatment caused a 35% increase in the distribution volume of SC terbutaline. After one week on oral terbutaline the concentration-effect relationship was shifted to the right and was steeper, with a higher EC50 of terbutaline and higher values for the apparent threshold concentration. These observations are compatible with a decrease in receptor numbers after 7 days of terbutaline in a system characterised by the presence of spare receptors. The data after prednisone pretreatment showed an apparent decline in the baseline plasma potassium concentrations that could be included in the Emax model. There was no change in the concentration-effect relationship 12 hours after prednisone.

Melphalan–prednisone–thalidomide (MPT and melphalan–prednisone–bortezomib (Velcade®, MPV, proved superior to MP, currently appear to be the treatments of choice for this population. In the near future melphalan–prednisone–lenalidomide (Revlimid®, MPR will also provide a third therapeutic option (MPT, MPV, and MPR, in elderly multiple myeloma, eventually. These options could lead to more personalized treatment approaches, based on patient comorbidities, as the three novel agents have somewhat different toxicity profiles. Dexamethasone-based regimen is another option and questions regarding the relative efficacy of melphalan-based versus low-dose dexamethasone-based regimens will require randomized phase III trials. More intensive approaches with new drug combinations or with the incorporation of polyethylene glycolated (PEGylated liposomal doxorubicin will also require additional studies. Additionally, the important issue of maintenance treatment needs to be further investigated. These new and emerging therapies offer multiple effective treatment options for MM patients and greatly enhanced treatment strategies for clinicians.Keywords: multiple myeloma, elderly, bortezomib, thalidomide, revlimid, IMiDs, supportive care

    After failure of erythropoiesis-stimulating agents (ESAs), lenalidomide (LEN) yields red blood cell (RBC) transfusion independence (TI) in 20-30% of lower-risk non-del5q myelodysplastic syndrome (MDS). Several observations suggest an additive effect of ESA and LEN in this situation. We performed a randomized phase III study in 131 RBC transfusion-dependent (TD, median transfusion requirement six RBC units per 8 weeks) lower-risk ESA-refractory non-del5q MDS. Patients received LEN alone, 10 mg per day, 21 days per 4 weeks (L arm) or LEN (same schedule) + erythropoietin (EPO) beta, 60,000 U per week (LE arm). In an intent-to-treat (ITT) analysis, erythroid response (HI-E, IWG 2006 criteria) after four treatment cycles (primary end point) was 23.1% (95% CI 13.5-35.2) in the L arm and 39.4% (95% CI 27.6-52.2) in the LE arm (P=0.044), while RBC-TI was reached in 13.8 and 24.2% of the patients in the L and LE arms, respectively (P=0.13). Median response duration was 18.1 and 15.1 months in the L and LE arms, respectively (P=0.47). Side effects were moderate and similar in the two arms. Low baseline serum EPO level and a G polymorphism of CRBN gene predicted HI-E. Combining LEN and EPO significantly improves erythroid response over LEN alone in lower-risk non-del5q MDS patients with anemia resistant to ESA.

    Full Text Available Abstract Background For therapeutic monitoring and pharmacokinetic studies of lenalidomide (LND, the potent drug for treatment of multiple myeloma (MM, a specific antibody was required for the development of a sensitive immunoassay system for the accurate determination of LND in plasma. Results In this study, a hapten of LND (N-glutaryl-LND was synthesized by introducing the glutaryl moiety, as a spacer, into the primary aromatic amine site of the LND molecular structure. The structure of the hapten (G-LND was confirmed by mass, 1H-NMR, and 13C spectrometric techniques. G-LND was coupled to each of bovine serum albumin (BSA and keyhole limpet hemocyanin (KLH proteins by ethyl-3-(3-dimethylaminopropyl carbodiimide as a coupling reagent. LND-KLH conjugate was used as an immunogen. Four female 2-3 months old New Zealand white rabbits were immunized with an emulsion of LND-KLH with Freund`s adjuvant. The immune response of the rabbits was monitored by direct enzyme-linked immunosorbent assay (ELISA using LND-BSA immobilized onto microwell plates as a solid phase. The rabbit that showed the highest antibody titer and affinity to LND was scarified and its sera were collected. The IgG fraction was isolated and purified by affinity chromatography on protein A column. The specificity of the purified antibody for LND was evaluated by indirect competitive ELISA using dexamethasone as a competitor as it is used with LND in a combination therapy. Conclusions The high affinity of the antibody (IC50 = 10 ng/mL will be useful in the development of an immunoassay system for the determination of plasma LND concentrations. Current research is going to optimize the assay conditions and validate the procedures for the routine application in clinical laboratories.

    The introduction of agents such as thalidomide, lenalidomide, and bortezomib has changed the management of patients with multiple myeloma who are not eligible for autologous transplantation, many of whom are elderly. We sought to compare three thalidomide-based oral regimens among such patients in Latin America. We randomized patients with newly diagnosed multiple myeloma with measurable disease to one of the following regimens: melphalan, prednisone, and thalidomide (MPT); cyclophosphamide, thalidomide, and dexamethasone (CTD); and thalidomide and dexamethasone (TD). The TD arm was closed prematurely and was analyzed only descriptively. The primary endpoint was the overall response rate (ORR), whereas progression-free survival (PFS) and overall survival (OS) were secondary endpoints. The accrual rate was slower than expected, and the study was terminated after 82 patients had been randomized. The ORRs were 67.9 % with MPT, 89.7 % with CTD, and 68.7 % with TD (p = 0.056 for the comparison between MPT and CTD). The median PFS was 24.1 months for MPT, 25.9 months for CTD, and 21.5 months for TD. There were no statistically significant differences in PFS or OS between MPT and CTD. In an unplanned logistic regression analysis, ORR was significantly associated with treatment with CTD (p = 0.046) and with performance status of 0 or 1 (p = 0.035). Based on the current results, no definitive recommendations can be made regarding the comparative merit of the regimens tested. Nevertheless and until the results of further studies become available, we recommend either CTD or MPT as suitable frontline regimens for patients with multiple myeloma who are not candidates to transplantation in settings where lenalidomide and bortezomib are not available.

    The first of the so-called "novel agents" (thalidomide, lenalidomide, and bortezomib), thalidomide has demonstrated activity as a single agent and in combination with other agents in patients with relapsed and/or refractory MM. The combination of melphalan, prednisone, and thalidomide (MPT) has become a standard treatment option for newly diagnosed patients who are ineligible for high-dose chemotherapy with autologous stem cell transplantation (ASCT). For patients intending to undergo ASCT, the combination of thalidomide, dexamethasone and cyclophosphamide can be used as a non-myelosuppressive induction regimen. Treatment with thalidomide is associated with an increased risk of developing peripheral neuropathy, which can be managed with dose reductions and discontinuation, and venous thromboembolism, which warrants thromboprophylaxis. While its adverse event profile may preclude prolonged use as maintenance therapy, thalidomide is an effective and well-tolerated salvage therapy option.

    The treatment of multiple myeloma is evolving rapidly. A plethora of doublet, triplet, and quadruplet combinations have been studied for the treatment of newly diagnosed myeloma. Although randomized trials have been conducted comparing older regimens such as melphalan-prednisone with newer regimens containing drugs such as thalidomide, lenalidomide, or bortezomib, there are few if any randomized trials that have compared modern combinations with each other. Even in the few trials that have done so, definitive overall survival or patient-reported quality-of-life differences have not been demonstrated. Therefore, there is marked heterogeneity in how newly diagnosed patients with myeloma are treated around the world. The choice of initial therapy is often dictated by availability of drugs, age and comorbidities of the patient, and assessment of prognosis and disease aggressiveness. This chapter reviews the current data on the most commonly used and tested doublet, triplet, and quadruplet combinations for the treatment of newly diagnosed myeloma and provides guidance on choosing the optimal initial treatment regimen.

    In Eastern Cooperative Oncology Group-ACRIN E4A03, on completion of four cycles of therapy, newly diagnosed multiple myeloma patients had the option of proceeding to autologous peripheral blood stem cell transplant (ASCT) or continuing on their assigned therapy lenalidomide plus low-dose dexamethasone (Ld) or lenalidomide plus high-dose dexamethasone (LD). This landmark analysis compared the outcome of 431 patients surviving their first four cycles of therapy pursuing early ASCT to those continuing on their assigned therapy. Survival distributions were estimated using the Kaplan–Meier method and compared with log-rank test. Ninety patients (21%) opted for early ASCT. The 1-, 2-, 3-, 4- and 5-year survival probability estimates were higher for early ASCT versus no early ASCT at 99, 93, 91, 85 and 80% versus 94, 84, 75, 65 and 57%, respectively. The median overall survival (OS) in the early versus no early ASCT group was not reached (NR) versus 5.78 years. In patients confidence interval: (0.50, 0.25). In patients ⩾65 years of age, median OS in the early versus no early ASCT was NR versus 5.11 years. ASCT dropped out of statistical significance (P=0.080). Patients opting for ASCT after induction Ld/LD had a higher survival probability and improvement in OS regardless of dexamethasone dose density. PMID:27588519

We also analyzed the relationships of CD40 expression with overall survival (OS and progression-free survival (PFS in DLBCL patients who were uniformly treated with R-CHOP. A low expression of CD40 compared to high expression is related to poor OS and PFS. Conclusion: Our findings indicate that the CD40 level at onset acts as an independent prognostic predictor of DLBCL patients treated with R-CHOP.

    Twenty-six evaluable patients were entered into two fractionated total body irradiation (TBI) programs; 11 patients received a course of 150 rad TBI (x 3 if tolerated) and 15 patients received a lower dose course of 50 rad (x 3 if tolerated). Complete remissions (CR) were not produced by either course; however, the higher dose course (Plan I) yielded a partial response (PR) rate of 73%, while the lower dose course yielded a PR of 47%. Although fraction size seemed trivial in both TBI plans, an unexpected high degree of hematologic toxicity was encountered, and was parallel to the response rates: in Plan I 73% of patients experienced severe to life-threatening depression of platelets or granulocytes, whereas in Plan II this rate was 47%. This was of short duration with rapid return of blood counts to normal levels. One death can be attributed to TBI. The chemotherapy arm of the study demonstrated superiority in terms of complete responses. Twenty-three percent of patients treated by cholrambucil and prednisone attained CR, in contrast to 0% of TBI patients. PR for chemotherapy was similar to that obtained with TBI. Chemotherapy also proved superior in terms of overall response rate, number of patients in remission, and in the median duration of response, but not in the median duration of survival. Fractional TBI techniques for active chronic lymphocytic leukemia (CLL) should be interrupted when the platelet count dips below 100,000 and the granulocyte count is lower than 2,000. Future studies should combine TBI radiation therapy and chemotherapy.

Methods Fifty Sprague- Dawley male rats at age of 3 months were randomly divided into five groups (10 per group) and treated with distilled water or prednisone or different dose berberine plus prednisone for 12 w. At the experimental endpoint, animals were drawn blood from right ventricle under anesthesia. The left half cerebrum was milled in 10% homogenate to test the content of monoamine oxidase ( MAO) and superoxide dismutase (SOD) . The right half cerebrum was for histological observation. Results After super-physiological dose of prednisone, the concentration of MAO was increased significantly in that of GC group( P < 0.01). The cells were arranged disorderly, dispersed, Dropsical and necrotic nerve cells were found in CA2 region of GC group. Yet Berberine prevented the changes of nerve centre in prednisone rats. Conclusions Cerebra damage occurs in three-month-old male Sprague-Dawley rats after prednisone-treated for 12 w. The treatment of Berberine in different dose can prevent the damage.

    Immunomodulatory drugs (IMiDs) are a cornerstone in the treatment of multiple myeloma (MM), but specific markers to predict outcome are still missing. Recent work pointed to a prognostic role for IMiD target genes (e.g. CRBN). Moreover, indirect activity of IMiDs on immune cells correlated with outcome, raising the possibility that cell populations in the bone marrow (BM) microenvironment could serve as biomarkers. We therefore analysed gene expression levels of six IMiD target genes in whole BM samples of 44 myeloma patients treated with lenalidomide-dexamethasone. Expression of CRBN (R = 0.30, P = .05), IKZF1 (R = 0.31, P = .04), IRF4 (R = 0.38, P = .01), MCT-1 (R = 0.30, P = .05), and CD147 (R = 0.38, P = .01), but not IKZF3 (R = -0.15, P = .34), was significantly associated with response. Interestingly, IKZF1 expression was elevated in BM environmental cells and thus selected for further investigation by multicolor flow cytometry. High IKAROS protein levels in total BM mononuclear cells (median OS 83.4 vs. 32.2 months, P = .02), CD19(+) B cells (median OS 71.1 vs. 32.2 months, P = .05), CD3(+) CD8(+) T cells (median OS 83.4 vs 19.0 months, P = .008) as well as monocytes (median OS 53.9 vs 18.0 months, P = .009) were associated with superior overall survival (OS). In contrast, IKAROS protein expression in MM cells was not predictive for OS. Our data therefore corroborate the central role of immune cells for the clinical activity of IMiDs and built the groundwork for prospective analysis of IKAROS protein levels in distinct cell populations as a potential biomarker for IMiD based therapies.

    BACKGROUND: Xianzhengubao capsule made from Cnidium, Epimedium and others has a certain protective role in glucocorticoid and retinoic acid-induced osteoporosis. OBJECTIVE: To study the effect of Xianzhengubao on different bones in prednisone-treated rats by bone histomorphometry and bone biomechanics methods. METHODS: Thirty-two Sprague-Dawley rats were randomly divided into control, prednisone, high- and low-dose Xianzhengubao groups. Rats in the latter groups were given prednisone at 3.5 mg/kg-d first to establish osteoporosis models. High- and low-dose Xianzhengubao groups were administrated with Xianzhengubao capsule at 0.95 g/kg-d and 0.475 g/kg-d, respectively, after prednisone treatment. RESULTS AND CONCLUSION: Compared with the control group, bone mineral density and biomechanical properties (elastic load, maximum load, break load) of the femur were significantly decreased in the prednisone group. Percent labeled perimeter, bone formation rate per bone surface and per unit of bone volume of the proximal tibial metaphysis were decreased in the prednisone group, but there was no significant difference both in static parameters of proximal tibial metaphysis and in tibial shaft. Compared with the prednisone group, bone mineral density and biomechanical properties of the femur, percent labeled perimeter and bone formation rate per bone surfaceof the proximal tibial metaphysis were increased, but there was no significant change in tibial shaft in the high-dose Xianzhengubao group. Compared with the prednisone group, there was no significant change in the low-dose Xianzhengubao group. The results demonstrates the Xianzhengubao can promote bone formation and prevent the decrease of bone mineral density and biomechanical properties of the femur in prednisone-treated rats, but has no effect on the cortical bone of the tibial shaft.%背景:仙珍骨宝胶囊由蛇床子、淫羊藿等制成,对糖皮质激素、维甲酸等诱发的骨质疏松有一定的预防作

    Bone marrow cells and peripheral blood mononuclear cells obtained from both acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) patients contain upregulated levels of cell surface antigen CD33 compared with healthy controls. This difference enables the use of humanized anti-CD33 antibody conjugated to cytotoxic agents for CD33 targeted immunotherapy. However, the expression of the membrane-bound drug transporter P-glycoprotein (P-gp) has been shown to be critical for resistance against the cytotoxicity of a humanized anti-CD33 antibody conjugated to maytansine-derivative DM4. The aim of the present study was to examine whether the expression of P-gp in AML cell lines is associated with changes in CD33 expression. For this purpose, we established drug resistant variants of SKM-1 and MOLM-13 AML cell lines via the selection of parental cells for resistance to vincristine, mitoxantrone and lenalidomide. All three substances induced a multidrug resistance (MDR) phenotype in SKM-1 cells associated with strong upregulation of P-gp and downregulation of CD33. However, in MOLM-13 cells, the upregulation of P-gp and downregulation of CD33 were present only in cells selected for resistance to vincristine and mitoxantrone but not lenalidomide. Inverse expression of P-gp and CD33 were observed in all resistant variants of SKM-1 and MOLM-13 cells. The MDR phenotype of resistant variants of SKM-1 and MOLM-13 cells was associated with alterations in apoptotic regulatory proteins and downregulation of the multidrug resistance associated protein 1 and breast cancer resistance protein.

    The objective of this study was to determine whether {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET) can adequately assess the risk of systemic disease progression in patients with primary, localized, high-grade soft tissue sarcomas of the extremities undergoing neoadjuvant isolated limb perfusion (ILP) with tumour necrosis factor and melphalan. This was a retrospective analysis of the files of 35 patients who underwent a PET or PET/CT scan prior to and after ILP followed by surgical resection with curative intent between 2006 and 2012. SUV{sub max1} was defined as the maximum standardized uptake value (SUV) at diagnosis, SUV{sub max2} as the maximum SUV after ILP and ΔSUV{sub max} as the percentage difference between SUV{sub max1} and SUV{sub max2}. The median follow-up was 40 months for all patients. The median SUV{sub max1} amounted to 7.6, while the median SUV{sub max2} was 4.7. The median ΔSUV{sub max} was -44 %. Overall survival (OS) probability at 2 and 5 years amounted to 78 and 70 %, respectively, while metastasis-free survival (MFS) probability at 2 and 5 years was 67 and 64 %, respectively. Receiver-operating characteristic (ROC) curve analysis showed that both SUV{sub max2} and ΔSUV{sub max} could predict systemic disease progression, while SUV{sub max1} could not adequately identify patients who went on to develop metastatic disease. The optimal cut-off value was 6.9 for SUV{sub max2} and -31 % for ΔSUV{sub max}. Patients with an SUV{sub max2} <6.9 had a 2-year MFS of 80 %, compared to 31 % for patients with an SUV{sub max2} ≥ 6.9 (p < 0.001). Patients with a ΔSUV{sub max} < -31 %, i.e. patients with a higher metabolic response, had an MFS of 76 % at 2 years, compared to 42 % for patients with a ΔSUV{sub max} ≥ -31 % (p = 0.050). SUV{sub max} after ILP for primary, locally advanced, non-metastatic high-grade soft tissue sarcomas of the extremities appears to be significantly correlated with prognosis. Whether patients

    The anti-inflammatory effect of high-dose inhaled corticosteroids (ICS) in children with asthma exacerbation is unknown. We aimed to investigate the efficacy of single-high dose ICS versus oral prednisone treatment followed by a course of six day high-dose ICS or oral prednisone (P) treatment on the concentrations of Cys-LTs and 8-isoprostane levels in the exhaled breath condensate (EBC) of children with asthma exacerbation. Ninety-four children with moderate-severe asthma exacerbation were evaluated with asthma scores, peak expiratory flow rate (PEF), forced expiratory volume in first second (FEV1) and exhaled Cys-LT and 8-isoprostane levels before and after treatment. EBC was collected from 52 patients before and four hours after treatment with inhaled fluticasone propionate (FP) (4000 μg) or P and after six days of treatment with FP-1000 μg/day or P. Cys-LTs and 8-isoprostane concentrations were determined using a specific immunoassay kit. Both single high-dose FP (n=59) and p (n=35) treatment resulted in a significant improvement in asthma score (pchildren with asthma exacerbation. High-dose ICS treatment may be useful in the treatment of children with asthma exacerbation. The effects start as early as after four hours. The suppression of Cys-LTs production contributes to the early effects. Suppression of both Cys-LTs and oxidants may favourably contribute to the effects observed later. Copyright © 2015 SEICAP.

    Aim: Previous studies have shown that D(+)β-3,4-dihydroxyphenyl lactic acid (salvianic acid A, SAA) has anabolic effects on prednisone (GC)-induced osteoporosis in rats. The current study aims to investigate the molecular mechanism of SAA's impact on osteogenesis and adipogenesis in bone marrow stromal cells in intact and GC-treated rats. Methods: For in vitro study, newborn rat calvaria osteoblasts (rOBs) and rat bone marrow stromal cells (rMSCs) were isolated, identified and cultured with SAA at different concentrations to evaluate SAA's influence on osteogenesis and adipogenesis. In addition, 3-month-old Sprague-Dawley (SD) male rats were treated with distilled water, prednisone alone (3.0mg·kg-1·d-1)or prednisone (3.0mg·kg-1·d-1)and SAA (25mg·kg-1·d-1)for 45d.At the end point,the different groups of rMSCs were isolated by density-gradient centrifugation and cultured. Results: (1) At 0.1-10.0 mg/L, SAA increased ALP activity, type I collagen (Coil-I) mRNA and OPG mRNA expression and stimulated nodule mineralization of rObs. SAA (0.5 mg/L) also significantly increased the ALP activity of rMSCs without a need for osteogenesis-inducing medium. At 5.0 mg/L, SAA decreased the number of adipocytes with less lipid droplet formation from the rMSCs, which typically undergo adipocyte induction. (2) Coll-I expression was markedly decreased, whereas lipoprotein lipase (LPL) mRNA expression increased by 98% when compared with the first generation of rMSCs in GC-treated rats. The SAA-treated rats demonstrated an over 2-fold increase in CoU-I expression when compared with intact rats and further showed a significant decrease in LPL expression when compared with GC-treated rats. When rMSCs were co-cultured with SAA (0.5 mg/L) in vitro, SAA did not affect Coll-I and LPL gene expression in intact rats but significantly increased Coll-I and decreased LPL gene expression in GC-treated rats.Conclusion: SAA protected bone from GC-induced bone marrow impairment by stimulating

    AIM: To investigate the significance and function of IFN-γ on the changes of peripheral blood platelet count during tumor-rejection induced by a low dose of melphalan in C57BL/6 mice. METHODS: Mouse tumor rejection model induced by a single dose of melphalan was used in this experiment. Different gene-type tumor-bearing mice (IFN-γ~(+/-) and IFN-γ~(-/-)), which had the same genetic background of C57BL/6, were treated intraperitoneally with melphalan (7.5 mg/kg). Tumor size was observed and recorded every one to three days in these different gene-type mice subsequently. Blood samples were obtained from orbital venous sinus on different days before and after melphalan treatment, and then complete blood counts were performed. The function of IFN-γ on the efficacy of chemotherapy and the changes of blood platelet count in IFN-γ~(+/-) and IFN-γ~(-/-) mice after melphalan treatment was analyzed. RESULTS: There was no significant difference in tumor sizes and blood platelet count between IFN-γ~(-/-) and IFN-γ~(+/-) mice (P>0.05). On the first day after melphalan (7.5 mg/kg) treatment, there were no significant changes in tumor sizes between mice in these two groups (P>0.05). Tumors shrank a little in IFN-γ~(-/-) mice and then grew gradually. Tumors relapsed in 2 w after melphalan injection in all IFN-γ~(-/-) mice, while tumor volumes decreased progressively and tumor cured at last in IFN-γ~(+/-) mice. The number of blood PLT in IFN-γ~(+/-) mice increased to (1935±378)×10~9/L 6 h after melphalan treatment, significantly higher than before (P0.05); While it sustained in normal range in IFN-γ~(-/-) mice. There was no significant difference in blood platelet count between IFN-γ~(-/-) and IFN-γ~(+/-) mice. CONCLUSION: Peripheral blood platelet count increased on the first day after melphalan treatment and tumors cured in IFN-γ~(+/-) mice; While tumors relapsed and there is no increase in blood platelet count on the first day after melphalan treatment in IFN

    Full Text Available PURPOSE: To investigate if colchicine is valuable in the treatment of Graves' ophthalmopathy (GO, we compared its effect with prednisone in 22 patients during the inflammatory phase of GO. METHODS: All patients, similar in age, sex and smoking habits, were euthyroid for at least 3 months and randomly divided into two groups, one treated with colchicine (1.5 mg/day and the other treated with prednisone (0.75 mg/kg/day. They were monitored with ophthalmologic assessment (clinical activity score-CAS and magnetic resonance imaging, using a signal intensity ratio (SIR of the recti muscles in comparison to the cerebral substantia alba. RESULTS: Amelioration of CAS was seen in 68% of the orbits in both groups. SIR also had a significant reduction after treatment: the initial median of 1.14 in G1 and 1.27 in G2, evolved, after treatment, to 1.07 in G1 and 0.69 in G2. The variation between both groups after treatment was not significant (p=0.22. None of the patients treated with colchicine had side effects; on the other hand, side effects in G2 were weight gain, edema, gastric complaints, hirsutism, weakness, depression, and alterations in blood pressure. CONCLUSION: Colchicine had a beneficial effect on the inflammatory phase of GO without the side effects of prednisone.OBJETIVO: Investigar se a colchicina é eficaz no tratamento da oftalmopatia de Graves, nós comparamos o seu efeito com a prednisona em 22 pacientes tratados na fase inflamatória da doença.
