About

Follicular Lymphoma (FL) is the second most common B-cell cancer and the most common type of cancer of lymphocytes. Unfortunately, this disease is incurable with conventional treatment and the disease recurs in almost all patients. This study will assess how safe and effective epcoritamab is in combination with lenalidomide and rituximab (R2) in treating adult participants with relapsed or refractory (R/R) FL. Adverse events and change in disease condition will be assessed.

Epcoritamab is an investigational drug being developed for the treatment of FL. Study doctors put the participants in 1 of 3 groups, called treatment arms. Each group receives a different treatment. Enrollment to one of the groups is closed. Around 500 adult participants with R/R FL will be enrolled in approximately 300 sites across the world.

Participants will receive R2 (375 mg/m^2 intravenous infusion of rituximab up to 5 cycles and oral capsules of 20 mg lenalidomide for up to 12 cycles) alone or in combination with subcutaneous injections of epcoritamab for up to 12 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.

Inclusion criteria

  • Eastern Cooperative Oncology Group (ECOG) performance status score 0 to 2.

  • Participant has:

    • Fluorodeoxyglucose-positron emission tomography (FDG-PET) scan demonstrating positive lesion compatible with computed tomography (CT) or magnetic resonance image (MRI)-defined anatomical tumor sites AND
    • >= 1 measurable nodal lesion (long axis > 1.5 cm) or >= 1 measurable extra-nodal lesion (long axis > 1.0 cm) on CT scan or MRI.
  • Histologically confirmed classic follicular lymphoma (FL) [previously Grade 1 to 3a FL] stage II, III, or IV with no evidence of histologic transformation to an aggressive lymphoma and CD20+ disease on most recent representative tumor biopsy based on the pathology report.

  • Relapsed or refractory (R/R) disease to at least one prior systemic regimen that contained an anti-CD20 monoclonal antibody (mAb) in combination with chemotherapy. (Participant who received only prior anti-CD20 mAb monotherapy and/or radiation therapy is not eligible.)

  • Eligible to receive R2 per investigator determination.

  • Estimated Creatinine Clearance (CrCl) >= 50 mL/min.

Exclusion criteria

  • Documented refractoriness to lenalidomide.
  • Have lenalidomide exposure within 12 months prior to randomization.
