Clinical Trial Summary

This study is a multicenter phase II trial including 2 cohorts of patients in Refractory/Relapse disease at least 1 month after CAR T-cells therapy: - cohort 1: DLBCL patients - cohort 2: PMBL, mantle cell lymphoma, transformed indolent NHL (t-iNHL) or iNHL CAR T-cells Refractory/Relapse status will be determined by PET-CT central review allowing inclusion in this trial. Patients enrolled will then receive a pre-phase of obinutuzumab followed by experimental treatment:11 cycle of glofitamab. The primary objective of the study is to assess the anti-lymphoma activity of glofitamab, a bispecific CD3xCD20 monoclonal antibody in patients with relapse/refractory DLBCL (cohort 1) disease after anti-CD19 CAR T-cells therapy
