Obinutuzumab, Zanubrutinib, and Lenalidomide in First-line Treatment of Mantle Cell Lymphoma

May 10, 2026 updated by: Institute of Hematology & Blood Diseases Hospital, China

Obinutuzumab, Zanubrutinib, and Lenalidomide as First-Line Therapy for Mantle Cell Lymphoma: A Prospective, Single-Arm, Open-Label, Multicenter Study

This is a prospective, open-label, single-arm clinical trial evaluating a treatment strategy for previously untreated Mantle Cell Lymphoma (MCL). The study will enroll patients who have not received prior systemic therapy for MCL. All patients will receive the ZGR induction regimen. Risk-adapted maintenance therapy will be applied: non-high-risk patients will receive lenalidomide and zanubrutinib maintenance for 1 and 2 years, respectively; high-risk patients will undergo CAR-T cell therapy followed by the same maintenance regimen. The primary objective is to assess the feasibility and preliminary efficacy of this treatment approach in the first-line setting of MCL.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
