Safety and Efficacy Study of Epcoritamab in Subjects With Relapsed/Refractory Chronic Lymphocytic Leukemia and Richter's Syndrome
Recruiting
I'm InterestedTrial ID: NCT04623541
Purpose
The study is a global, multi-center safety and efficacy trial of epcoritamab, an antibody
also known as EPKINLY™ and GEN3013 (DuoBody®-CD3xCD20). Epcoritamab will either be studied
as:
- Monotherapy, or
- Combination therapy:
- epcoritamab + venetoclax
- epcoritamab + lenalidomide
- epcoritamab + R-CHOP (i.e., rituximab, cyclophosphamide, doxorubicin hydrochloride,
vincristine and prednisone).
The study includes patients with relapsed/refractory chronic lymphocytic leukemia (R/R
CLL)/small lymphocytic lymphoma (SLL) and patients with Richter's Syndrome (RS).
Study participants with R/R CLL/SLL are treated either with epcoritamab as monotherapy or
epcoritamab + venetoclax. Study participants with RS are treated either with epcoritamab as
monotherapy or epcoritamab + lenalidomide or epcoritamab + R-CHOP. The trial consists of two
parts, a dose-escalation phase (phase Ib) and an expansion phase (phase II). Patients with RS
are only included in the expansion phase.

2. Received any prior allogeneic hematopoietic stem cell transplantation (HSCT) or solid
organ transplantation.
3. Received (CAR) T-cell therapy within 100 days or an investigational drug within 4
weeks, prior to first dose of epcoritamab.
4. Autoimmune disease or other diseases that require permanent or high-dose
immunosuppressive therapy.
5. Received vaccination with live vaccines within 28 days.
