The purpose of this study is to evaluate the safety and efficacy of glofitamab, as monotherapy and in combination with a standard chemoimmunotherapy regimen: rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) in pediatric and young adult participants with relapsed and refractory (R/R) mature B-cell non-Hodgkin lymphoma (B-NHL).
Age 6 months to < 18 years at the time of signing Informed Consent for Cohort A Part 1 and Cohort B of the study, and age 6 months to < 30 years old at the time of signing Informed Consent for Cohort A Part 2 of the study
Histologically re-confirmed diagnosis, via tissue biopsy, or bone marrow aspirate, pleural effusion, or ascites, prior to study entry of aggressive mature B-NHL that expresses CD20 (reconfirmed by IHC or flow cytometry if IHC is not possible), including BL, BAL (mature B-cell leukemia FAB L3), DLBCL, and PMBCL, at the time of first R/R disease for Cohort A and second or greater R/R disease for Cohort B
Refractory or relapsed disease (i.e., prior treatment was ineffective or intolerable) following first-line standard-of-care chemoimmunotherapy for Cohort A and following at least two prior systemic chemoimmunotherapy regimens and who have exhausted all available established therapies for Cohort B
Measurable disease, defined as: At least one bi-dimensionally measurable nodal lesion, defined as > 1.5 cm in its longest dimension, or at least one bi dimensionally measurable extranodal lesion, defined as > 1.0 cm in its longest dimension; or percentage of bone marrow involvement with lymphoma cells defined by cytomorphological analysis of bone marrow aspirates
Isolated CNS disease of mature B-NHL without systemic involvement, and primary CNS lymphoma
Receipt of glofitamab prior to study enrollment
Ongoing adverse events from prior anti-cancer therapy that were not resolved to Grade ≤ 1 (exceptions: alopecia, Grade 2 peripheral neuropathy)
Grade ≥ 3 adverse events, with the exception of Grade 3 endocrinopathy managed with replacement therapy
