Refractory Diffuse Large B-Cell Lymphoma (DLBCL)

The goal of this Phase 2, open-label, multicenter clinical trial is to assess the efficacy and safety of accelerated ramp-up and fixed-dose subcutaneous epcoritamab combined with lenalidomide in adults with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) following progression after second-line CAR T-cell therapy. The main question it aims to answer is : \- What is the overall response rate (ORR) after Cycle 2, or at premature treatment discontinuation (PTD), according to the 2014 Lugano Response Criteria? Participants will: * Receive subcutaneous epcoritamab administered according to an accelerated ramp-up schedule followed by fixed dosing, in combination with lenalidomide. * Undergo clinical evaluations, laboratory assessments, and PET-CT imaging to determine disease status based on the 2014 Lugano Response Criteria. * Continue study therapy for up to 48 weeks. * Enter a follow-up period of at least 24 months after the last dose to monitor long-term outcomes and safety. Approximately 55 adults will be enrolled across multiple centers in France. Eligible individuals must have R/R LBCL, including diffuse large B-cell lymphoma and other eligible LBCL subtypes, with progressive metabolic disease documented by PET-CT at least 1 month after second-line CAR T-cell therapy. The overall study duration is expected to be approximately 5 years.

The purpose of this phase I study is to determine whether MDC-CAR-BCMA001 (BCMA directed CAR T-cells) is safe and tolerable in the treatment of relapsed and refractory B-cell malignancies

This is an observational long-term follow-up (LTFU) study for subjects who previously received zamtocabtagene autoleucel, known as MB-CART2019.1.

DALY II USA is a phase II, multi-center, single arm study to evaluate the efficacy, safety, and pharmacokinetics of zamtocabtagene autoleucel (MB-CART2019.1) in patients with relapsed and/or refractory B cell lymphoma (BCL). Cohorts include subjects with diffuse large B-cell lymphoma (DLBCL) after receiving at least 2 lines of therapy, primary or secondary central nervous system (CNS) lymphoma (PCNSL) and (SCNSL) after receiving at least one line of therapy, mantle cell lymphoma (MCL) and Richter's transformation (RT) after receiving at least one line of therapy, and DLBCL transplant-ineligible after receiving at least one line of therapy.
