Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with histologically confirmed CD20+ DLBCL who have relapsed or refractory disease after at least one line of systemic therapy.

Probably not a fit

Patients who have not been previously treated for DLBCL or those with other types of lymphoma may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the safety and effectiveness of subcutaneously injected epcoritamab combined with oral lenalidomide against the intravenous administration of rituximab, gemcitabine, and oxaliplatin in adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Approximately 320 participants will be enrolled across 165 sites globally, with participants assigned to one of two treatment arms. The study will monitor adverse events and changes in disease condition over a treatment period of up to 12 cycles, each lasting 28 days.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with relapsed or refractory DLBCL.

How similar studies have gone: Other studies have shown promising results with similar treatment approaches, but this specific combination is being evaluated for the first time.
