Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with relapsed or refractory follicular lymphoma or marginal zone lymphoma who have received at least one prior line of systemic therapy.

Probably not a fit

Patients who have not been previously treated with anti-CD20 monoclonal antibodies 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 investigates the safety and efficacy of an experimental drug called odronextamab combined with lenalidomide in adults with relapsed or refractory follicular lymphoma (FL) or marginal zone lymphoma (MZL). The study consists of two parts: the first part assesses the safety and tolerability of the drug combination, while the second part compares its effectiveness against a standard treatment of rituximab combined with lenalidomide. Participants must have measurable disease and a history of prior treatment with anti-CD20 monoclonal antibodies. This combination treatment is considered first-in-human as it has not been previously tested together in humans.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with difficult-to-treat lymphoma types.

How similar studies have gone: Other studies have shown success with similar drug combinations in treating lymphomas, but this specific combination is novel.

3. History of or current relevant CNS pathology, as described in the protocol.
4.

5. Any other significant active disease or medical condition that could interfere with the conduct of the study or put the participant at significant risk, as described in the protocol.
6. Allergy/hypersensitivity to study drugs or excipients. as described in the protocol.
