Summary

This phase II trial tests how well odronextamab works before and after standard of care (SOC) chimeric antigen receptor (CAR) T-cell therapy in treating patients with diffuse large B-cell lymphoma (DLBCL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). CAR-T cell therapy is the SOC treatment most patients receive when other treatments have failed. CAR-T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Odronextamab is a monoclonal antibody that is called bispecific, as it individually targets 2 cell proteins, CD20 and CD3. Proteins are part of each cell in the body, which work together like little machines for the cell to function. CD20 is a protein that is found on the surface of both normal B-cells and B-cells that make up certain cancers, like DLBCL. CD3 is a protein that is found on the surface of T cells. T-cells and normal B-cells are types of white blood cells in the body and are a part of the immune system that fights infections. Odronextamab is designed to help T-cells find and kill the B-cells including the cancer cells in DLBCL. Giving odronextamab before and after CAR T-cell therapy may improve response in patients with relapsed or refractory DLBCL.
