Refractory T-Cell/Histiocyte-Rich Large B-Cell Lymphoma

This phase II trial tests how well venetoclax, ibrutinib, prednisone, obinutuzumab, and Revlimid® (ViPOR) works in treating patients with CD10 negative diffuse large B-cell lymphoma (DLBCL) and high-grade lymphoma with MYC and BCL2 rearrangements that has come back after a period of improvement (relapsed) and/or that has not responded to previous treatment (refractory). 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. Ibrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell (a type of white blood cells) cancers at abnormal levels. This may help keep cancer cells from growing and spreading. Anti-inflammatory drugs, such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Obinutuzumab, a monoclonal antibody, binds to a protein called CD20, which is found on B cells and some types of leukemia and lymphoma cells. Obinutuzumab may block CD20 and help the immune system kill cancer cells. Revlimid, a type of anti-angiogenesis agent and a type of immunomodulating agent, may help the immune system kill abnormal blood cells or cancer cells. It may also prevent the growth of new blood vessels that cancers need to grow. ViPOR may be an effective treatment option for patients with relapsed and/or refractory CD10 negative DLBCL and high-grade B-cell lymphoma with MYC and BCL2 rearrangements.

This phase II trial tests the effectiveness of golcadomide and rituximab as bridging treatment before chimeric antigen receptor (CAR) T-cell therapy in patients with aggressive B-cell non-Hodgkin lymphoma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Patients that are able to receive CAR T-cell therapy have a potential for cure, however, many will not be qualified to receive therapy due to relapse. Bridging therapy is therapy intended to transition a patient from one therapy or medication to another or maintain their health or status until they are a candidate for a therapy or have decided on a therapy. Golcadomide may help block the formation, growth or spread of cancer cells. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving golcadomide and rituximab as bridging therapy before CAR T-cell therapy may kill more tumor cells and may improve the chance of proceeding to CAR T-cell therapy in patients with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma.

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.
