Safety and Efficacy Trial of Epcoritamab Combinations in Subjects With B-cell Non-Hodgkin Lymphoma (B-NHL) (EPCORE™ NHL-2)

June 1, 2026 updated by: Genmab

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)

The purpose of this trial is to measure the safety and effectiveness of epcoritamab (EPKINLY™), either by itself or together with other therapies, when treating participants with B-cell non-Hodgkin Lymphoma (B-NHL). The aim of the first part of the trial is to identify the most appropriate dose of epcoritamab, and the aim of the second part of the trial is to assess the selected epcoritamab dose in a larger group of participants with B-NHL. All participants in this trial will receive either epcoritamab alone, or epcoritamab combined with another standard treatment regimen, with a total of 10 different treatment arms being studied.

Trial details include:

  • The treatment duration for each participant depends upon which arm of treatment they are assigned to.
  • The visit frequency for each participant depends upon which arm of treatment they are assigned to, but will be weekly to start for all participants, then will decrease to either: every 2 weeks, or every 3 weeks, or every 4 weeks, or every 8 weeks.
  • All participants will receive active drug; no one will be given placebo.

Participants who receive treatment with epcoritamab will have it injected right under the skin. Participants will receive a different regimen of epcoritamab depending upon which arm of treatment they are assigned.

Participants who receive standard treatments will have intravenous (IV) infusions and/or oral administration of those treatments. Participants will receive a different standard treatment regimen depending upon which arm of treatment they are assigned.

Study Overview

Detailed Description

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 participants with 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 participants with previously untreated diffuse large B-cell lymphoma (DLBCL)
  • Arm 2: epcoritamab + rituximab and lenalidomide (R2) in participants with relapsed/refractory (R/R) follicular lymphoma (FL)
  • Arm 3: epcoritamab + rituximab and bendamustine (BR) in participants with previously untreated FL
  • Arm 4: epcoritamab + rituximab, cytarabine, dexamethasone, and oxaliplatin/ carboplatin (R-DHAX/C) in participants with R/R DLBCL eligible for autologous stem cell transplant (ASCT)
  • Arm 5: epcoritamab + gemcitabine and oxaliplatin (GemOx) in participants with R/R DLBCL ineligible for ASCT due to age, performance status (PS), or comorbidity
  • Arm 6: epcoritamab + R2 in participants with previously untreated FL
  • Arm 7: epcoritamab maintenance in participants with FL who achieve a complete response (CR) or a partial response (PR) following first or second line SOC treatment
  • Arm 8: epcoritamab + reduced dose of R-CHOP (R mini-CHOP) in participants with previously untreated DLBCL who are ineligible to receive full-dose anthracycline
  • Arm 9: epcoritamab + lenalidomide for second-line treatment in participants with R/R FL who progressed within 24 months of initiation of first-line anti-CD20-containing immunochemotherapy
  • Arm 10: epcoritamab + rituximab, ifosfamide, carboplatin, and etoposide phosphate (R-ICE) in participants with R/R DLBCL eligible for ASCT

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 and Arm 10. Part 2 includes all 10 arms (Arm 1-10) and the primary goal of all arms, except Arm 7, is preliminary efficacy. For Arm 7, the primary goal is safety. Participants in Arm 1-5 and Arm 10 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 participants in Arm 8 during a 28-day period (safety run-in). The arms are conducted in parallel.

Cohort 2a will be dosed weekly (QW) in Cycles 1-3, once every 2 weeks (Q2W) in Cycles 4-9, and once every 4 weeks (Q4W) in Cycle 10 and beyond for up to 2 years.

In cohort 2b, an alternate dosing schedule for epcoritamab will be explored: epcoritamab administered QW for Cycles 1-2 only, then Q4W in Cycle 3 and beyond for up to 2 years.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Part 1: Number of Participants With Dose limiting Toxicities (DLTs)
Time Frame: During the first cycle (Cycle length= 28 days) in each cohort
DLT events are defined as clinically significant adverse events (AEs) or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications as assessed per Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria version 5.0.
During the first cycle (Cycle length= 28 days) in each cohort
Part 2 (Except Arm 7): Overall Response Rate (ORR)
Time Frame: Up to 3 years
ORR is defined as the percentage of participants achieving complete response (CR) or partial response (PR) based on Lugano criteria.
Up to 3 years
Part 1 and Part 2 (Arms 1-5, 7 and 10): Number of Participants With Adverse Events (AEs)
Time Frame: From first dose of drug until either 60 days after last dose, date participant withdraws consent, date participant starts a new systemic anticancer therapy, or date participant dies, whichever occurs first (up to approximately 3 years)
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign. (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
From first dose of drug until either 60 days after last dose, date participant withdraws consent, date participant starts a new systemic anticancer therapy, or date participant dies, whichever occurs first (up to approximately 3 years)
