Summary
Brief summary
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.
