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

Official Title

A Phase 1b/2, Open-Label Trial to Assess the Safety and Preliminary Efficacy of Epcoritamab (GEN3013; DuoBody®-CD3xCD20) in Combination With Other Agents in Subjects With B-cell Non-Hodgkin Lymphoma (B-NHL)


All participants in the trial will receive epcoritamab, as monotherapy or in combination. 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 (DLBCL)
  • 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, cytarabine, dexamethasone, and oxaliplatin/ carboplatin (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
  • Arm 6: epcoritamab + R2 in subjects with previously untreated FL
  • Arm 7: epcoritamab maintenance in subjects with FL who achieve a complete response (CR) or a partial response (PR) with SOC treatment
  • Arm 8: epcoritamab + reduced dose of R-CHOP (R mini-CHOP) in subjects with previously untreated DLBCL who are ineligible to receive full-dose anthracycline

The trial consists of two parts: Part 1 ('Dose Escalation') and Part 2 ('Dose Expansion'). The primary objective of Part 1 is safety, and it includes Arm 1-5. Part 2 includes all 8 arms (Arm 1-8) and the primary goal of all arms, except Arm 7, is preliminary efficacy. For Arm 7, the primary goal is safety. Patients in Arm 1-5 can only participate in either Part 1 or Part 2. Dose Limiting Toxicities (DLTs) will be assessed in Part 1 and for a selected number of patients in Arm 8 during a 28-day period ('safety-run phase'). The arms are conducted in parallel.
