What was measured

Peak was defined as the maximum post-baseline level of the cytokine.

Analysis population: Participants from the Safety Analysis Set 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.

Cohort 2: 0.5 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 0.5 x 10\^6 anti-CD19 CAR T cells/kg, with a maximum dose of 0.5 x 10\^8 anti-CD19 CAR T cells for participants ≥ 100 kg on Day 0.
