Comparing Rituximab and Mosunetuzumab Drug Treatments for People With Low Tumor Burden Follicular Lymphoma

United States600 participantsStarted 2024-10-23

Plain-language summary

This phase III trial compares the effectiveness of rituximab to mosunetuzumab in treating patients with follicular lymphoma with a low tumor burden. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. It is not yet known if giving rituximab or mosunetuzumab works better in treating patients with follicular lymphoma with a low tumor burden.

Inclusion Criteria: * Participants must have a histologically confirmed diagnosis of classic follicular lymphoma (cFL). cFL was previously categorized as grade 1-3A per World Health Organization (WHO)-HAEM4R, but grading of classic follicular lymphoma (FL) is no longer mandatory. * NOTE: Participants with follicular lymphoma with uncommon features (uFL) are eligible, including FL with diffuse growth pattern (dFL). Diagnosis is as per local pathology. Lymphoma fluorescence in situ hybridization (FISH) is not required. Molecular testing is not required. * Participants must not have follicular lymphoma with "blastoid" or "large centrocyte" cytological features, or follicular large B-cell lymphoma (FLBL) (previously categorized as follicular lymphoma grade 3B) * Participants must have low-tumor burden follicular lymphoma defined as: * Nodal or extra-nodal tumor mass with diameter less than 7 cm in its greater diameter * Involvement of no more than 3 nodal or extra nodal sites with diameter greater than 3 cm. * Absence of B symptoms which may include unexplained fever, drenching sweats, unintentional weight loss (more than 10% of body weight) * No symptomatic splenomegaly * No compression syndrome (ureteral, orbital, gastrointestinal) * No pleural or peritoneal serous effusion related to follicular lymphoma Participants must have Ann Arbor stage II, III, or IV follicular lymphoma. Participants with stage I disease may be included if they do not wish to undergo rad…
