About this trial
BrUOG-401 is a prospective, single-arm, phase 2 trial of first-line therapy in adult patients with previously untreated FL or MZL. All patients will be assigned the same initial treatment plan, modified by interim response assessment (IRA) after Cycle 4. All patients will start treatment with four 21-day cycles (C1-4) of mosunetuzumab alone (using step-up dosing during C1), followed by IRA. Patients who achieve CR at IRA will continue with additional 4 cycles (C5-8) of mosunetuzumab. Patients who achieve PR at IRA will receive mosunetuzumab with lenalidomide augmentation during C5-8. Primary response assessment (PRA) will occur after C8. Patients who remain in PR at PRA will continue for additional 4 cycles (extended augmentation).
Eligibility criteria
Qualifiers
Ability to understand and the willingness to sign a written informed consent document and to comply with the study protocol procedures.
Age ≥18 years at the time of signing informed consent. Because no dosing or adverse event data are currently available on the use of mosunetuzumab in patients <18 years of age, they are excluded from this study.
follicular lymphoma (grade 1, 2, 3a, or not otherwise specified) or
marginal zone lymphoma (nodal, extranodal, or splenic), according to 2016 WHO classification and confirmed to express the CD20 antigen by immunohistochemistry or flow cytometry. Patients in whom definitive pathologic subtype of FL/MZL is undetermined due to limited biopsy material can be enrolled if in the investigator's opinion integrated clinicopathologic data are consistent with the eligible diagnosis.
Disqualifiers
Grade 3b follicular lymphoma or transformed lymphoma.
Prior treatment with any anti-CD20 antibody or lenalidomide for lymphoma.
Prior stem cell transplantation (autologous or allogeneic) or prior solid organ transplantation.
History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies or known sensitivity or allergy to murine products.
