The event did not necessarily have a relationship with study treatment. AE included worsening of a pre-existing medical condition. Worsening indicated that the pre-existing medical condition had increased in severity, frequency, and/or duration or had an association with a worse outcome. A pre-existing condition that had not worsened during the study or involved an intervention such as elective cosmetic surgery or a medical procedure while on study, was not considered an AE. TEAE was defined as any AE with onset on or after the start of treatment.","groups":[{"description":"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.","id":"OG000","title":"Cohort 1: 2 x 10^6 Brexucabtagene Autoleucel"},{"description":"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.","id":"OG001","title":"Cohort 2: 0.5 x 10^6 Brexucabtagene Autoleucel"}],"paramType":"NUMBER","populationDescription":"Participants from the Safety Analysis Set were analyzed.","reportingStatus":"POSTED","timeFrame":"Up to 5 years","title":"Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAE)","type":"SECONDARY","unitOfMeasure":"percentage of participants"}
