Trial Summary
What is the purpose of this trial?This phase I/II trial tests the safety and effectiveness of glofitamab (with obinutuzumab pretreatment), venetoclax, and lenalidomide in treating patients with newly diagnosed, high risk mantle cell lymphoma. Glofitamab and obinutuzumab are monoclonal antibodies that may interfere with the ability of cancer cells to grow and spread. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Lenalidomide works by helping the immune system kill cancer cells and by helping the bone marrow to produce normal blood cells. Giving venetoclax, glofitamab with obinutuzumab, and lenalidomide together may kill more cancer cells in patients with newly diagnosed, high risk mantle cell lymphoma.
What data supports the idea that Combination Therapy for Mantle Cell Lymphoma is an effective treatment?The available research shows that combining venetoclax with lenalidomide and rituximab is effective for patients with untreated mantle cell lymphoma. In a study with 28 patients, 96% showed a positive response, and 86% had no detectable disease after treatment. This combination therapy is considered safe and effective, with no severe side effects reported. Compared to other treatments, such as single-agent therapies, this combination shows promising results in achieving high response rates.346710
What safety data is available for the combination therapy for Mantle Cell Lymphoma?The safety data for the combination therapy involving Venetoclax, Obinutuzumab, and other agents like Lenalidomide and Glofitamab can be inferred from studies on Venetoclax in various conditions. Venetoclax, a BCL-2 inhibitor, has been studied in combination with Obinutuzumab for chronic lymphocytic leukemia (CLL), showing an acceptable tolerability profile with manageable adverse events such as neutropenia. In relapsed/refractory CLL, Venetoclax combined with Rituximab showed a manageable safety profile. In multiple myeloma, Venetoclax combined with Carfilzomib and Dexamethasone was well tolerated, with common adverse events including diarrhea and fatigue. Overall, Venetoclax in combination therapies has shown promising safety and efficacy profiles across different studies.23568
Is the drug combination of Glofitamab, Lenalidomide, Obinutuzumab, and Venetoclax promising for treating mantle cell lymphoma?Yes, the combination of these drugs is promising for treating mantle cell lymphoma. Studies show that adding Venetoclax to Lenalidomide and Rituximab (similar to Obinutuzumab) is safe and effective, with high response rates in patients. This suggests that the combination therapy could be a strong option for treating this type of cancer.147910
Do I need to stop my current medications to join the trial?The trial protocol does not specify if you must stop all current medications. However, you cannot take warfarin, strong or moderate CYP3A inhibitors, or strong CYP3A inducers within 4 weeks before starting the study drug. Ongoing corticosteroid use over 30 mg/day of prednisone or equivalent is also not allowed unless it's for cancer symptom control. Please consult with the trial team for guidance on your specific medications.
Eligibility Criteria
This trial is for adults aged 18-80 with newly diagnosed, high-risk mantle cell lymphoma who haven't had cancer treatment before.

Lenalidomide in combination with rituximab for patients with relapsed or refractory mantle-cell lymphoma: a phase 1/2 clinical trial. [2023]The combination of rituximab and lenalidomide has shown promise for the treatment of mantle-cell lymphoma (MCL) in preclinical studies. We aimed to identify the maximum tolerated dose (MTD) of lenalidomide when combined with rituximab in a phase 1 trial and to assess the efficacy and safety of this combination in a phase 2 trial in patients with relapsed or refractory MCL.
Venetoclax: First Global Approval. [2018]Venetoclax (Venclexta™) is an oral selective inhibitor of the prosurvival protein BCL-2 and therefore restores the apoptotic ability of malignant cells. The drug arose from research by Abbott Laboratories (now AbbVie) during a collaboration with Genentech and is being co-developed by AbbVie and Genentech/Roche primarily for the treatment of haematological malignancies. Venetoclax is approved in the USA for use as monotherapy in patients with chronic lymphocytic leukaemia (CLL) with the 17p deletion (as detected by an approved FDA test) who have received at least one prior therapy, and is awaiting approval for similar indications in the EU and Canada. Venetoclax is also in phase I-III development as combination therapy for CLL, phase I/II development as monotherapy and/or combination therapy for non-Hodgkin lymphomas (including diffuse large B-cell lymphoma, mantle cell lymphoma, follicular lymphoma) and acute myeloid leukaemia, and phase I development for multiple myeloma, systemic lupus erythematosus and breast cancer. This article summarizes the milestones in the development of venetoclax leading to this first approval for CLL.
Venetoclax: A Review in Relapsed/Refractory Chronic Lymphocytic Leukemia. [2020]Venetoclax (Venclyxto®; Venclexta®) is a first-in-class, oral, selective B cell lymphoma-2 (BCL-2) inhibitor. The drug is approved in numerous countries, including those of the EU and in the USA, for the treatment of adults with relapsed or refractory (RR) chronic lymphocytic leukemia (CLL); the specific indication(s) for venetoclax may vary between individual countries. Venetoclax monotherapy or combination therapy with rituximab was an effective treatment, provided durable responses, and had a manageable safety profile in pivotal clinical trials in adults with RR CLL, including in patients with adverse prognostic factors. In combination with 6 cycles of rituximab, venetoclax (fixed 24 months' treatment) was more effective than bendamustine plus rituximab (6 cycles) in prolonging progression-free survival (PFS) and inducing undetectable minimal residual disease (uMRD) in peripheral blood (PB) and bone marrow (BM), with these benefits sustained during 36 months' follow-up. Hence, with its novel mechanism of action and convenient oral once-daily regimen, venetoclax monotherapy or fixed 24-month combination therapy with rituximab represents an important option for treating RR CLL, including in patients with del(17p) or TP53 mutation and those failing a B cell receptor (BCR) inhibitor and/or chemotherapy.
Efficacy of venetoclax in high risk relapsed mantle cell lymphoma (MCL) - outcomes and mutation profile from venetoclax resistant MCL patients. [2020]Venetoclax is effective in relapsed patients with mantle cell lymphoma (MCL). Mechanisms of resistance to venetoclax in MCL are poorly understood. We describe the clinical outcomes and genomic characteristics of 24 multiply relapsed patients (median of five prior lines of therapy) who received venetoclax-based therapies; 67% had progressed on BTK inhibitors (BTKi) and 54% had blastoid or pleomorphic histology. Median follow up after venetoclax treatment was 17 months. The overall response rate was 50% and complete response (CR) rate was 21%, 16 patients had progressed and 15 died. The median progression free, overall and post venetoclax survival were 8, 13.5 and 7.3 months respectively. Whole-exome sequencing (WES) was performed on samples collected from seven patients (including five pairs; before starting venetoclax and after progression on venetoclax). The SMARCA4 and BCL2 alterations were noted only after progression, while TP53, CDKN2A, KMT2D, CELSR3, CCND1, NOTCH2 and ATM were altered 2-4-fold more frequently after progression. In two patients with serial samples, we demonstrated clonal evolution of novel SMARCA4 and KMT2C/D mutations at progression. Mutation dynamics in venetoclax resistant MCL is demonstrated. Our data indicates that venetoclax resistance in MCL is predominantly associated with non-BCL2 gene mutations. Further studies are ongoing in MCL patients to evaluate the efficacy of venetoclax in combination with other agents and understand the biology of venetoclax resistance in MCL.
Phase 1/2 study of venetoclax, a BCL-2 inhibitor, in Japanese patients with relapsed or refractory chronic lymphocytic leukemia and small lymphocytic lymphoma. [2021]Patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have limited treatment options. Venetoclax is a potent BCL-2 inhibitor that induces apoptosis in CLL cells. This open-label, phase 1/2 study (NCT02265731) evaluated the safety, pharmacokinetics, and efficacy of venetoclax in Japanese patients with R/R CLL/SLL. Patients enrolled in phase 1 received 400 mg/day venetoclax monotherapy. Patients enrolled in phase 2 received 400 mg/day venetoclax, plus rituximab. Venetoclax was administered with a weekly stepwise ramp-up in doses. In phase 2, efficacy was evaluated by objective response rate (ORR). Twelve patients were enrolled, six in each arm. The most common grade ≥ 3 adverse events were neutropenia (83%), lymphopenia (67%), leukopenia (33%), and thrombocytopenia (17%). Patients receiving venetoclax monotherapy achieved an ORR of 100%, including a complete remission (CR) rate of 17%. Patients receiving combination therapy had an ORR of 67% and a CR rate of 50%. The venetoclax pharmacokinetics profile in Japanese patients was similar to that of Western patients. Venetoclax 400 mg/day monotherapy or in combination with rituximab was well-tolerated and induced promising responses in Japanese patients with R/R CLL/SLL. Although patient numbers were small, the safety profile was largely consistent with other Western studies. Clinical trial registration: clinicaltrials.gov; NCT02265731.
Venetoclax: A Review in Previously Untreated Chronic Lymphocytic Leukaemia. [2021]Venetoclax (Venclexta®; Venclyxto®) is a first-in-class, oral, selective inhibitor of B cell lymphoma 2 (BCL2). In several countries, including the USA and those of the EU, venetoclax is indicated in combination with obinutuzumab for the treatment of adult patients with previously untreated chronic lymphocytic leukaemia (CLL). Approval was based on the results of the phase III CLL14 trial in patients with previously untreated CLL and co-existing conditions. In this study, fixed-duration (12 months) targeted treatment with venetoclax + obinutuzumab resulted in significantly longer progression-free survival (PFS; primary endpoint) relative to fixed-duration chemoimmunotherapy with chlorambucil + obinutuzumab. Venetoclax + obinutuzumab was also associated with significantly higher rates of undetectable minimal residual disease (MRD), complete response and overall response than chlorambucil + obinutuzumab. Improvements in clinical outcomes with venetoclax + obinutuzumab were maintained during long-term follow-up, when all patients had been off treatment for ≥ 2 years. No significant between-group difference was observed in overall survival (OS). Venetoclax had an acceptable tolerability profile. Notable adverse events such as grade 3 or 4 neutropenia can be managed with supportive therapy and venetoclax dose modifications. In conclusion, fixed-duration venetoclax + obinutuzumab represents an important chemotherapy-free first-line treatment option for patients with CLL, particularly those who are not fit enough to receive intensive chemoimmunotherapy.
Relapsed Mantle Cell Lymphoma: Current Management, Recent Progress, and Future Directions. [2023]The increasing number of approved therapies for relapsed mantle cell lymphoma (MCL) provides patients effective treatment options, with increasing complexity in prioritization and sequencing of these therapies. Chemo-immunotherapy remains widely used as frontline MCL treatment with multiple targeted therapies available for relapsed disease. The Bruton's tyrosine kinase inhibitors (BTKi) ibrutinib, acalabrutinib, and zanubrutinib achieve objective responses in the majority of patients as single agent therapy for relapsed MCL, but differ with regard to toxicity profile and dosing schedule. Lenalidomide and bortezomib are likewise approved for relapsed MCL and are active as monotherapy or in combination with other agents. Venetoclax has been used off-label for the treatment of relapsed and refractory MCL, however data are lacking regarding the efficacy of this approach particularly following BTKi treatment. Anti-CD19 chimeric antigen receptor T-cell (CAR-T) therapies have emerged as highly effective therapy for relapsed MCL, with the CAR-T treatment brexucabtagene autoleucel now approved for relapsed MCL. In this review the authors summarize evidence to date for currently approved MCL treatments for relapsed disease including sequencing of therapies, and discuss future directions including combination treatment strategies and new therapies under investigation.
Phase 2 study of venetoclax plus carfilzomib and dexamethasone in patients with relapsed/refractory multiple myeloma. [2022]Proteins in the antiapoptotic B-cell lymphoma 2 (BCL-2) family play a role in the pathophysiology of multiple myeloma (MM). Venetoclax is a highly selective, potent, oral BCL-2 inhibitor that induces apoptosis of MM cells, and its efficacy may be potentiated through combination with agents that increase BCL-2 dependency or have complementary mechanisms of action. The safety, tolerability, pharmacokinetics, and antitumor activity of venetoclax in combination with carfilzomib and dexamethasone (VenKd) in adults with relapsed/refractory MM (RRMM) were investigated in this phase 2 dose-escalation study. Oral venetoclax (400 or 800 mg) was administered daily in combination with intravenous carfilzomib (27, 56, or 70 mg/m2) and oral dexamethasone (20 or 40 mg) in 4 dose-finding cohorts. The expansion cohort received venetoclax 800 mg, carfilzomib 70 mg/m2, and dexamethasone 40 mg. Forty-nine patients received treatment. Median prior lines of therapy was 1 (range, 1-3), and median time in the study was 27 months. The most common treatment-emergent adverse events were diarrhea (65%), fatigue (47%), nausea (47%), and lymphopenia (35%). Serious adverse events occurred in 26 (53%) patients. Of 3 treatment-emergent deaths, 1 was considered treatment related. The overall response rate was 80% in all patients, 92% in patients with t(11;14) (n = 13), and 75% in patients without (n = 36). The rate of complete response or better was 41%. Median progression-free survival was 22.8 months. Treatment with VenKd was well tolerated and showed promising response rates in this RRMM patient population, with greater responses observed in patients with t(11;14). This trial is registered at www.clinicaltrials.gov as #NCT02899052.
A Phase II Study of Venetoclax in Combination With Pomalidomide and Dexamethasone in Relapsed/Refractory Multiple Myeloma. [2022]Venetoclax is a selective BCL-2 inhibitor with clinical activity in relapsed/refractory multiple myeloma (RRMM). Combinations of venetoclax with agents that have complementary mechanisms of action may improve venetoclax efficacy in RRMM. This study evaluated venetoclax with pomalidomide and dexamethasone (VenPd) in RRMM.
Adding venetoclax to lenalidomide and rituximab is safe and effective in patients with untreated mantle cell lymphoma. [2023]Mantle cell lymphoma (MCL) is a rare, incurable hematological malignancy with a heterogeneous presentation and clinical course. A wide variety of chemotherapy-based regimens are currently used in patients who are untreated. Over the last several years, several targeted or small-molecule therapies have shown efficacy in the relapsed/refractory setting and have since been explored in the frontline setting. Lenalidomide plus rituximab was explored in a phase 2 study of 38 patients with MCL who were untreated and ineligible to receive transplantation, in which the combination produced durable remissions. We looked to build upon this regimen by adding venetoclax to the combination. We conducted a multicenter, open-label, nonrandomized, single-arm study to evaluate this combination. We enrolled 28 unselected patients with untreated disease irrespective of age, fitness, or risk factors. Lenalidomide was dosed at 20 mg daily from days 1 to 21 of each 28-day cycle. The dose of venetoclax was determined using the time-to-event continual reassessment method. Rituximab was dosed at 375 mg/m2 weekly, starting on cycle 1, day 1 until cycle 2, day 1. No dose-limiting toxicities were noted. All patients were treated with venetoclax at the maximum tolerated dose of 400 mg daily. The most common adverse events were neutropenia and thrombocytopenia. The overall and complete response rates were 96% and 86%, respectively. In total, 86% of patients achieved minimal residual disease undetectability via next-generation sequencing. The median overall and progression-free survivals were not reached. The combination of lenalidomide, rituximab, and venetoclax is a safe and effective regimen in patients with untreated MCL. This trial was registered at www.clinicaltrials.gov as #NCT03523975.
