Project description:There is an unmet need for effective biological therapies for relapsed central nervous system (CNS) lymphoma. Lenalidomide is active in activated B-cell type diffuse large B-cell lymphoma and rituximab is effective in CNS lymphoma. These observations are the basis for this first trial of an immunomodulatory drug as monotherapy in CNS lymphoma, and, in patients with inadequate responses to lenalidomide, with rituximab. In an independent cohort, we evaluated lenalidomide maintenance after salvage with high-dose methotrexate or focal irradiation in relapsed primary CNS lymphoma (PCNSL). We determined safety, efficacy, and cerebrospinal fluid (CSF) penetration of lenalidomide at 10-, 15-, and 20-mg dose levels in 14 patients with refractory CD20+ CNS lymphoma. Nine subjects with relapsed, refractory CNS lymphoma achieved better than partial response with lenalidomide monotherapy, 6 maintained response ≥9 months, and 4 maintained response ≥18 months. Median progression-free survival for lenalidomide/rituximab was 6 months. In the independent cohort, response duration with lenalidomide maintenance after complete responses 2 through 5 were significantly longer than response durations after standard therapy. The CSF/plasma partition coefficient of lenalidomide was ≥20% at 15- and 20-mg dose levels. Change in CSF interleukin-10 at 1 month correlated with clinical response and response duration to lenalidomide. Metabolomic profiling of CSF identified novel biomarkers, including lactate, and implicated indoleamine-2,3 dioxygenase activity with CNS lymphoma progression on lenalidomide. We conclude that lenalidomide penetrates ventricular CSF and is active as monotherapy in relapsed CNS lymphomas. We provide evidence that maintenance lenalidomide potentiates response duration after salvage in relapsed PCNSL and delays whole brain radiotherapy (WBRT). This trial was registered at www.clinicaltrials.gov as #NCT01542918.

Project description:BackgroundThe aim of the study was to evaluate the cost-effectiveness of lenalidomide plus rituximab vs rituximab alone in patients with relapsed or refractory indolent lymphoma.MethodsA Markov decision model was established to carry out the cost-effectiveness analysis. Three discrete health states, progression-free survival (PFS), progressive disease (PD), and death, were included. Cycle length was set at 1 month, and utility scores were derived from previously published literature. The incremental cost-effectiveness ratio (ICER) was defined as the primary endpoint, and the willingness-to-pay (WTP) threshold was set at $29,306.43 per quality-adjusted life year (QALY). Both cost and effectiveness were determined using a 3% annual discount rate. Furthermore, one-way and probabilistic sensitivity analyses were performed to check the robustness of the model.ResultsLenalidomide plus rituximab gained 6.08 QALYs at a cost of $120,979.62 while rituximab alone gained 4.84 QALYs at a cost of $48,052.11. The ICER of lenalidomide plus rituximab vs rituximab alone was $58,812.51/QALY. The parameters most significantly influenced the model were the utility values for the PFS state, the duration of the PFS state in the lenalidomide plus rituximab group, and the cost of lenalidomide. The probability of lenalidomide plus rituximab or rituximab alone being the most cost-effective option was 0% and 100%, respectively, at a WTP threshold of $29,306.43/QALY.ConclusionsLenalidomide plus rituximab is not a cost-effective strategy compared with rituximab monotherapy for relapsed or refractory indolent lymphoma from a Chinese societal perspective.

Project description:PurposePatients with indolent non-Hodgkin lymphoma typically respond well to first-line immunochemotherapy. At relapse, single-agent rituximab is commonly administered. Data suggest the immunomodulatory agent lenalidomide could increase the activity of rituximab.MethodsA phase III, multicenter, randomized trial of lenalidomide plus rituximab versus placebo plus rituximab was conducted in patients with relapsed and/or refractory follicular or marginal zone lymphoma. Patients received lenalidomide or placebo for 12 cycles plus rituximab once per week for 4 weeks in cycle 1 and day 1 of cycles 2 through 5. The primary end point was progression-free survival per independent radiology review.ResultsA total of 358 patients were randomly assigned to lenalidomide plus rituximab (n = 178) or placebo plus rituximab (n = 180). Infections (63% v 49%), neutropenia (58% v 23%), and cutaneous reactions (32% v 12%) were more common with lenalidomide plus rituximab. Grade 3 or 4 neutropenia (50% v 13%) and leukopenia (7% v 2%) were higher with lenalidomide plus rituximab; no other grade 3 or 4 adverse event differed by 5% or more between groups. Progression-free survival was significantly improved for lenalidomide plus rituximab versus placebo plus rituximab, with a hazard ratio of 0.46 (95% CI, 0.34 to 0.62; P < .001) and median duration of 39.4 months (95% CI, 22.9 months to not reached) versus 14.1 months (95% CI, 11.4 to 16.7 months), respectively.ConclusionLenalidomide improved efficacy of rituximab in patients with recurrent indolent lymphoma, with an acceptable safety profile.

Project description:IntroductionTafasitamab plus lenalidomide (TAFA + LEN) received accelerated US Food and Drug Administration approval and conditional European Medicines Agency approval for treatment of adults with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) not eligible for autologous stem cell transplant. This study investigates the relative efficacy of TAFA + LEN versus comparator treatments.MethodsMatching-adjusted indirect comparisons (MAICs) of TAFA + LEN were performed using data from L-MIND, and comparator studies assessing rituximab-based combination therapies, including polatuzumab vedotin + bendamustine + rituximab (POLA + BR) bendamustine + rituximab (BR), and gemcitabine + oxaliplatin + rituximab (R-GEMOX) to provide relative efficacy estimates for overall survival (OS), progression-free survival (PFS), duration of response (DOR), objective response rate (ORR), and complete response rate (CRR). Patient-level data from L-MIND were weighted to match reported distributions of clinically validated prognostic factors and effect modifiers in comparator trials. MAIC results versus multiple BR studies were pooled using meta-analysis.ResultsMAICs were feasible versus POLA + BR and BR. Compared to POLA + BR, TAFA + LEN was associated with significantly longer DOR [hazard ratio (HR) 0.34 (95% CI 0.12, 0.98); p = 0.045]. Due to concerns about the proportional hazard assumption for OS and PFS, separate HRs were estimated before and after 4 months of follow-up. OS after 4 months, was significantly greater for TAFA + LEN versus POLA + BR [HR 0.41 (95% CI 0.19, 0.90); p = 0.026]. Compared with BR, TAFA + LEN was associated with significantly improved OS [GO29365 comparator trial: HR 0.39 (95% CI 0.18, 0.82); p = 0.014], PFS (pooled data: HR 0.39 (95% CI 0.29, 0.53); p < 0.001], DOR [pooled data: HR 0.35 (95% CI 0.25, 0.50); p < 0.001], and CRR [pooled data: odds ratio 2.43 (95% CI 1.33, 4.41); p = 0.004].ConclusionIn MAIC analyses, treatment with TAFA + LEN for R/R DLBCL provided better OS and PFS outcomes than standard treatment regimens. Validation from large, randomized, phase 3 clinical trials is required to confirm these results.

Project description:This single-arm phase 3 study was conducted to confirm the results of our phase 2 study of bendamustine (B)-rituximab (R) in patients with relapsed/refractory diffuse large B cell lymphoma (rrDLBCL). The primary endpoint was overall response rate (ORR). Autologous stem cell transplantation-ineligible rrDLBCL patients with ≤ 2 prior chemotherapy regimens received R 375 mg/m2 IV on day 1 and B 120 mg/m2/day IV on days 2 and 3 every 21 days up to 6 cycles. Thirty-eight patients with a median age of 74 years (range, 43-86) received BR. The ORR and complete response rates were 76.3% and 47.4%, respectively. With a median follow-up of 19.5 months including long-term follow-up, median progression-free survival was 11.9 months. Median OS was 29.2 months. Discontinuation of treatment due to Gr3-5 TEAE was observed among 13 of 38 patients (34.2%). One patient with cytomegalovirus enterocolitis died during follow-up. This BR regimen was confirmed to be effective and tolerable in studied patients. ClinicalTrials.gov Identifier: NCT03372837 registered on 14 December 2017, NCT04354402 registered on 21 April, 2020.

Project description:BackgroundMantle-cell lymphoma is generally incurable. Initial treatment is not standardized but usually includes cytotoxic chemotherapy. Lenalidomide, an immunomodulatory compound, and rituximab, an anti-CD20 antibody, are active in patients with recurrent mantle-cell lymphoma. We evaluated lenalidomide plus rituximab as a first-line therapy.MethodsWe conducted a single-group, multicenter, phase 2 study with induction and maintenance phases. During the induction phase, lenalidomide was administered at a dose of 20 mg daily on days 1 through 21 of every 28-day cycle for 12 cycles; the dose was escalated to 25 mg daily after the first cycle if no dose-limiting adverse events occurred during the first cycle and was reduced to 15 mg daily during the maintenance phase. Rituximab was administered once weekly for the first 4 weeks and then once every other cycle until disease progression. The primary end point was the overall response rate. Secondary end points included outcomes related to safety, survival, and quality of life.ResultsA total of 38 participants were enrolled at four centers from July 2011 through April 2014. The median age was 65 years. On the basis of the Mantle Cell Lymphoma International Prognostic Index scores, the proportions of participants with low-risk, intermediate-risk, and high-risk disease at baseline were similar (34%, 34%, and 32%, respectively). The most common grade 3 or 4 adverse events were neutropenia (in 50% of the patients), rash (in 29%), thrombocytopenia (in 13%), an inflammatory syndrome ("tumor flare") (in 11%), anemia (in 11%), serum sickness (in 8%), and fatigue (in 8%). At the median follow-up of 30 months (through February 2015), the overall response rate among the participants who could be evaluated was 92% (95% confidence interval [CI], 78 to 98), and the complete response rate was 64% (95% CI, 46 to 79); median progression-free survival had not been reached. The 2-year progression-free survival was estimated to be 85% (95% CI, 67 to 94), and the 2-year overall survival 97% (95% CI, 79 to 99). A response to treatment was associated with improvement in quality of life.ConclusionsCombination biologic therapy consisting of lenalidomide plus rituximab was active as initial therapy for mantle-cell lymphoma.

Project description:RE-MIND2 (NCT04697160) compared patient outcomes from the L-MIND (NCT02399085) trial of tafasitamab+lenalidomide with those of patients treated with other therapies for relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who are autologous stem cell transplant ineligible. We present outcomes data for three pre-specified treatments not assessed in the primary analysis. Data were retrospectively collected from sites in North America, Europe, and the Asia Pacific region. Patients were aged ≥18 years with histologically confirmed DLBCL and received ≥2 systemic therapies for DLBCL (including ≥1 anti-CD20 therapy). Patients enrolled in the observational and L-MIND cohorts were matched using propensity score-based 1:1 nearest-neighbor matching, balanced for six covariates. Tafasitamab+lenalidomide was compared with polatuzumab vedotin+bendamustine+rituximab (pola-BR), rituximab+lenalidomide (R2), and CD19-chimeric antigen receptor T-cell (CAR-T) therapies. The primary endpoint was overall survival (OS). Secondary endpoints included treatment response and progression-free survival. From 200 sites, 3,454 patients were enrolled in the observational cohort. Strictly matched patient pairs consisted of tafasitamab+lenalidomide versus pola-BR (n = 24 pairs), versus R2 (n = 33 pairs), and versus CAR-T therapies (n = 37 pairs). A significant OS benefit was observed with tafasitamab+lenalidomide versus pola-BR (HR: 0.441; p = 0.034) and R2 (HR: 0.435; p = 0.012). Comparable OS was observed in tafasitamab+lenalidomide and CAR-T cohorts (HR: 0.953, p = 0.892). Tafasitamab+lenalidomide appeared to improve survival outcomes versus pola-BR and R2, and comparable outcomes were observed versus CAR-T. Although based on limited patient numbers, these data may help to contextualize emerging therapies for R/R DLBCL. CLINICAL TRIAL REGISTRATION: NCT04697160 (January 6, 2021).

Project description:AbstractPatients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) ineligible for available salvage therapies have limited options for long-term disease control, necessitating novel treatments. Previously, magrolimab (anti-cluster-of-differentiation-47 antibody) plus rituximab (M+R) demonstrated ability to induce complete responses (CR) in R/R DLBCL. Here, we report 3-year follow-up data from this phase 1b/2 study assessing long-term safety and efficacy of M+R, and initial safety and efficacy of M+R plus gemcitabine-oxaliplatin (M+R-GemOx), in R/R DLBCL. After magrolimab priming, 4 groups of patients received M+R, 10 to 45 mg/kg magrolimab with 375 mg/m2 rituximab; patients receiving M+R-GemOx received 30 or 45 mg/kg magrolimab with 375 mg/m2 rituximab, 1000 mg/m2 gemcitabine, and 100 mg/m2 oxaliplatin. Primary end points were treatment-emergent adverse events (TEAEs) and objective response rate (ORR). Secondary end points included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Of 132 patients treated, 99 received M+R and 33 received M+R-GemOx. Most common any-grade TEAEs were fatigue (M+R, 40%; M+R-GemOx, 70%), infusion-related reactions (M+R, 39%), or anemia (M+R-GemOx, 70%). Treatment-related TEAEs led to magrolimab discontinuation in 7% (M+R) and 6% (M+R-GemOx). One death was considered treatment related (M+R-GemOx, colitis). M+R ORR was 24% (CR, 12%), and median DOR was 9.3 months. Median PFS and OS were 1.8 and 9.2 months, respectively. M+R-GemOx ORR was 52% (CR, 39%); 12-month DOR rate was 66.6% (95% confidence interval, 33.1-86.1). Median PFS and OS were 3.9 months and not reached, respectively. These results demonstrate that M+R with/without GemOx is well tolerated, and M+R-GemOx has clinical activity in patients with R/R DLBCL. This trial was registered at www.clinicaltrials.gov as #NCT02953509.
