What was measured

OR: CR or PR. CR: disappearance of all detectable clinical evidence; typically FDG-avid lymphoma (a post-treatment residual mass of any size is permitted if it is PET negative); variably FDG-avid lymphomas/FDG avidity unknown (all lymph nodes and nodal masses must have regressed to normal size); spleen and/or liver should be normal size and not be palpable; bone marrow aspirate and biopsy must show no evidence of disease. PR: 50% decrease in the SPD of up to 6 largest dominant nodal masses and ≥ 50% decrease in SPD of spleen/liver nodules; no increase in size of nodes, liver, or spleen and no new sites of disease; splenic and hepatic nodules must regress by ≥ 50% in the SPD; if participant has persistent bone marrow involvement and otherwise meets criteria for CR, will then be considered a PR; typically FDG-avid lymphoma (the post-treatment PET scan should be positive in at least 1 previously involved site. Percentages were rounded off.

Analysis population: Participants from the mITT Analysis Set in Cohort 1 were analyzed.

Groups in this outcome

Cohort 1: 2 x 10^6 Brexucabtagene Autoleucel

Participants with relapsed/refractory MCL received conditioning chemotherapy consisting of fludarabine 30 mg/m\^2/day and cyclophosphamide 500 mg/m\^2/day IV infusion for 3 days followed by a single infusion of brexucabtagene autoleucel at a targeted dose of 2 x 10\^6 anti-CD19 CAR T cells/kg, with a maximum dose of 2 x 10\^8 anti-CD19 CAR T cells for participants ≥ 100 kg on Day 0.
