Details and patient eligibility


The drug that will be investigated in the study is an antibody, epcoritamab, also known as EPKINLY™ and GEN3013. Since the safety and tolerability of epcoritamab has already been studied in previous studies in humans, the main purpose of this study is to evaluate efficacy. To evaluate this, half of the participants who are eligible will receive epcoritamab and the other half will receive a pre-specified investigator's choice of chemotherapy. Epcoritamab will be studied in R/R DLBCL participants who did not respond to a previous autologous stem cell transplant (ASCT) or do not meet the criteria for ASCT

Full description

The trial is an open label, multi-center, global phase 3 randomized trial of epcoritamab, GEN3013. The goal of this randomized trial is to evaluate the efficacy of epcoritamab (GEN3013, DuoBody®-CD3xCD20) compared to investigator's choice of chemotherapy, in patients with relapsed, refractory diffuse large B-Cell Lymphoma who have failed or are ineligible for high-dose chemotherapy and autologous stem cell transplant (HDT-ASCT). No change in chemotherapy is permitted for participants during the treatment phase of the trial.
