Purpose

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 subjects 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 total trial duration will be up to 6 years. - The treatment duration for each participant depends upon which arm of treatment they are assigned to receive, but will be no more than 3 years. - The visit frequency for each participant depends upon which arm of treatment they are assigned to receive, 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 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.

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) with 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. Patients 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 patients in Arm 8 during a 28-day period ('safety-run phase'). The arms are conducted in parallel.
