Evaluating a new treatment combination for follicular lymphoma

A Phase Ib/II, Open-Label, Multicenter Study With a Non-Randomized Stage Evaluating the Safety, Pharmacokinetics, and Efficacy of Mosunetuzumab Plus Lenalidomide (+Len), and a Randomized Stage Evaluating the Safety, Tolerability, and Pharmacokinetics of SC Versus IV Mosunetuzumab + Len in Patients With Follicular Lymphoma

Phase1; Phase2 Interventional Hoffmann-La Roche · NCT04246086

This study is testing a new combination of treatments for follicular lymphoma to see how well they work and if giving one of the medications through an IV or under the skin is safer.

What this trial studies

This study evaluates the safety and efficacy of a combination treatment involving mosunetuzumab and lenalidomide in patients with follicular lymphoma. It aims to compare the pharmacokinetics and safety of administering mosunetuzumab either intravenously or subcutaneously. Participants will be monitored for their response to treatment, including any side effects and overall effectiveness. The study includes both Phase 1 and Phase 2 assessments to gather comprehensive data on the treatment's performance.

Who should consider this trial

Good fit: Ideal candidates include individuals with relapsed or refractory follicular lymphoma who have received at least one prior systemic therapy.

Not a fit: Patients with untreated follicular lymphoma who do not require systemic therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with follicular lymphoma.

How similar studies have performed: Other studies have shown promise with similar immunotherapy approaches, indicating potential for success in this area.
