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…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
