A Study Evaluating the Safety, Pharmacokinetics, and Efficacy of Mosunetuzumab + Lenalidomide (+Len), and the Safety, Tolerability, and Pharmacokinetics of SC Versus IV Mosunetuzumab + Len in Participants With Follicular Lymphoma

Running, not enrolling · Phase 1/Phase 2

Conditions studied: Follicular Lymphoma

In brief

This study will evaluate the safety, efficacy, pharmacokinetics, and immunogenicity of mosunetuzumab (Mosun) + lenalidomide (Len) (Mosun + Len) in participants with follicular lymphoma (FL). This study will also compare the pharmacokinetics, pharmacodynamics, safety, efficacy, and immunogenicity of IV mosunetuzumab + len vs subcutaneous (SC) mosunetuzumab + len.

Women must refrain from donating eggs during this same period
For men: agreement to remain abstinent or use contraceptive measures and agreement to refrain from donating sperm, with female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 2 months after the final dose of glofitamab, 28 days after last dose of Len, 18 months after the last dose of G, 3 months after the final dose of tocilizumab, and 3 months after the final dose of Mosun
