Summary

"This trial compares two drugs, rituximab and mosunetuzumab, in treating patients with low tumor burden follicular lymphoma. Rituximab targets a protein found on B

Who is the study for?
This trial is for people with a confirmed diagnosis of classic follicular lymphoma without 'blastoid' features or grade 3B. They should have a low tumor burden, meaning no more than 3 large tumors and none bigger than 7 cm. Participants must not have severe symptoms, spleen enlargement, organ compression issues, or fluid buildup due to the cancer.
What is being tested?
The trial compares rituximab (a monoclonal antibody targeting CD20 on B cells) with mosunetuzumab (another monoclonal antibody that may stop cancer cells from growing). It's unclear which treatment is better for patients with low tumor burden follicular lymphoma.
What are the potential side effects?
Potential side effects include immune system reactions like fever and chills, infections due to lowered white blood cell counts, infusion-related reactions such as rash or difficulty breathing, and possible damage to healthy organs.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Arm II (Mosunetuzumab)Experimental Treatment4 Interventions
Patients receive mosunetuzumab SC on days 1, 8 and 15 of cycle 1 and on day 1 of subsequent cycles. Cycles repeat every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan and/or PET/CT and blood sample collection on study and during follow up.
Group II: Arm I (Rituximab, rituximab and hyaluronidase)Experimental Treatment5 Interventions
Patients receive rituximab IV on day 1 of cycle 1 and receive rituximab and hyaluronidase SC on days 8, 15 and 22 of cycle 1 and SC on day 1 of subsequent cycles. Cycles repeat every 56 days for up to 5 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan and/or PET/CT and blood sample collection on study and during follow up.
