Low Dose Mosunetuzumab for Indolent B-Cell Lymphoma
University of Washington
Summary
This phase II trial tests the safety, side effects and effectiveness of mosunetuzumab in treating patients with slow growing (indolent) B-cell lymphoma. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread.
Description
OUTLINE: Patients receive mosunetuzumab intravenously (IV) over 2-4 hours on days 1, 8, 15 and 22. Patients also undergo blood sample collection and positron emission tomography (PET)/computed tomography (CT) on study. Patients may undergo CT and/or magnetic resonance imaging (MRI) as clinically indicated and may undergo collection of oral and/or rectal swabs on study. After completion of study treatment, patients are followed up at week 13, at 6 months, and then for up to 5 years per institutional standards.
