Golcadomide and Rituximab as Bridging Therapy for Relapsed or Refractory Aggressive B-cell Non-Hodgkin Lymphoma Before CAR T-cell Therapy

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.
