Safety and Efficacy Trial of Epcoritamab Combinations in Subjects With B-cell Non-Hodgkin Lymphoma

Trial Status: Active

A phase 1b / 2, open-label, multinational, interventional trial to evaluate the safety, tolerability, PK, pharmacodynamics / biomarkers, immunogenicity, and preliminary efficacy of epcoritamab in combination with other standard of care (SOC) agents in subjects with B-NHL.

The following regimens will be investigated:

- Arm 1: epcoritamab + rituximab, cyclophosphamide, doxorubicin, vincristine, and

prednisone (R-CHOP) in subjects with previously untreated diffuse large B-cell lymphoma


- Arm 2: epcoritamab + rituximab and lenalidomide (R2) in subjects with

relapsed/refractory (R/R) follicular lymphoma (FL)

- Arm 3: epcoritamab + rituximab and bendamustine (BR) in subjects with previously

untreated FL

- Arm 4: epcoritamab + rituximab, cisplatin, cytarabine, and dexamethasone (R-DHAX/C) in

subjects with R/R DLBCL eligible for autologous stem cell transplant (ASCT)

- Arm 5: epcoritamab + gemcitabine and oxaliplatin (GemOx) in subjects with R/R DLBCL

ineligible for ASCT due to age, performance status (PS), or comorbidity

For each arm, there are 2 parts: Part 1 (dose escalation) and Part 2 (expansion). Within each

arm, subjects can only participate in one part.
