The trial is an open-label, multi-center safety trial of epcoritamab GEN3013 (DuoBody®-CD3xCD20). The trial consists of two parts: a dose escalation part phase 1, first-in-human (FIH) and an expansion part phase 2a.

Official Title

A Phase 1/2, Open-Label Safety Trial of GEN3013 in Patients With Relapsed, Progressive or Refractory B-Cell Lymphoma


The purpose of the escalation part of the trial is to determine the maximum tolerated dose and the recommended phase 2 dose (RP2D) as well as to establish the safety profile of epcoritamab GEN3013 (DuoBody®-CD3xCD20) in patients with relapsed, progressive or refractory B-Cell Lymphoma. In the expansion part additional patients will be treated with epcoritamab with the RP2D and the purpose is to further explore and determine the safety and efficacy of epcoritamab.
