A Study of Subcutaneously Injected Epcoritamab Plus Oral Lenalidomide Tablets Compared to Intravenously (IV) Infused Rituximab Plus IV Infused Gemcitabine and IV Infused Oxaliplatin in Adult Participants With Relapsed or Refractory Diffuse Large B-Cell Lymphoma

ClinicalTrials ID:NCT06508658

Patient View

This study evaluates the safety and efficacy of Epcoritamab plus Lenalidomide versus Rituximab plus Gemcitabine and Oxaliplatin in adults with relapsed/refractory DLBCL. Eligible participants must have CD20+ DLBCL, prior treatment history, and meet specific criteria regarding ASCT and CAR-T therapy. Interventions include SC injections, oral capsules, and IV infusions.

Patient Parameters

Program Overview

B-cell Lymphoma is an aggressive and rare cancer of a type of immune cells (a white blood cell responsible for fighting infections). This study will assess how safe and effective epcoritamab plus lenalidomide (E-Len) is compared to rituximab plus gemcitabine and oxaliplatin (R-GemOx) )in treating adult participants with relapsed or refractory (R/R) Diffuse Large B-Cell Lymphoma (DLBCL). Adverse events and change in disease condition will be assessed.

Epcoritamab is an investigational drug being developed for the treatment of DLBCL. Study doctors put the participants in 1 of 2 groups, called treatment arms. Each group receives a different treatment. Around 320 adult participants with R/R DLBCL will be enrolled in approximately 165 sites across the world.

Participants in arm A will receive subcutaneous (SC) injections of epcoritamab plus oral lenalidomide capsules (E-Len) for up to 12 cycles (each cycle is 28 days). Participants "in arm B will receive intrav... (IV) infused R-GemOx for up to 4 cycles (each cycle is 28 days)

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

      • Lymphocyte apheresis failure.
      • Unwilling to receive CAR-T therapy.
      • Unable to receive CAR-T therapy due to financial, geographic, insurance, access, and/or manufacturing constraints.

Exclusion Criteria

  • Documented refractoriness to lenalidomide.
