Official title
Odronextamab for Relapsed/Refractory Large B-Cell Lymphomas Before Definitive Lymphoma-Directed Therapies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial tests the effectiveness of odronextamab given before chimeric antigen receptor T (CAR-T) cell therapy (bridging therapy) in patients with large B-cell lymphomas that have come back after a period of improvement (relapsed) or that have not responded to previous treatment (refractory). Odronextamab is a bispecific antibody that can bind to two different antigens at the same time. Odronextamab binds to CD3, a T-cell surface antigen, and CD20 (a tumor-associated antigen that is expressed on B-cells during most stages of B-cell development and is often overexpressed in B-cell cancers) and may interfere with the ability of cancer cells to grow and spread. Bridging therapy has been used to maintain disease control and to increase the chance of successful receipt of CAR-T cell therapy. However, bridging therapy is typically given after leukapheresis, which does not help prevent disease progression between the decision for CAR-T cell therapy and leukapheresis. Giving odronextamab as bridging therapy before leukapheresis may delay disease progression to allow leukapheresis and increase the likelihood of successful CAR-T cell therapy in patients with relapsed or refractory large B-cell lymphomas.
