Time frame
First infusion date of axicabtagene ciloleucel to the date of death regardless of cause (maximum duration: 7.7, 6.8, 5.4, 4.4, 4.1 years for Cohorts 1, 2, 3, 4, 5, and 6 respectively)

What was measured

OS was defined as the time from axicabtagene ciloleucel infusion to the date of death. Participants who did not die by the analysis data cutoff date were censored at their last contact date. KM estimates was used for analyses.

Analysis population: Participants in the mITT Analysis Set were analyzed.

Groups in this outcome

Phase 2 (Pivotal Study): Cohort 1

Participants with refractory DLBCL received conditioning chemotherapy (fludarabine 30 mg/m\^2 IV over 30 minutes and cyclophosphamide 500 mg/m\^2 IV over 60 minutes) on Days -5, -4, and -3; followed by a single infusion of axicabtagene ciloleucel CAR transduced autologous T cells administered IV at a target dose of 2 x 10\^6 anti-CD19 CAR T cells/kg of BW on Day 0.

Phase 2 (Pivotal Study): Cohort 2

Participants with refractory PMBCL or TFL received conditioning chemotherapy (fludarabine 30 mg/m\^2 IV over 30 minutes and cyclophosphamide 500 mg/m\^2 IV over 60 minutes) on Days -5, -4, and -3; followed by a single infusion of axicabtagene ciloleucel CAR transduced autologous T cells administered IV at a target dose of 2 x 10\^6 anti-CD19 CAR T cells/kg of BW on Day 0.

Phase 2 (Safety Management Study): Cohort 3

Participants with relapsed or refractory transplant ineligible DLBCL, PMBCL, or TFL received conditioning chemotherapy (fludarabine 30 mg/m\^2 IV over 30 minutes and cyclophosphamide 500 mg/m\^2 IV over 60 minutes) on Days -5, -4, and -3; followed by a single infusion of axicabtagene ciloleucel CAR transduced autologous T cells administered IV at a target dose of 2 x 10\^6 anti-CD19 CAR T cells/kg of BW on Day 0. Participants also received a prophylactic regimen of levetiracetam (750 mg orally or IV twice daily (BID) starting on Day 0) and tocilizumab (8 mg/kg IV over 1 hour (not to exceed 800 mg)) on Day 2).

Phase 2 (Safety Management Study): Cohort 6

Participants with r/r DLBCL, PMBCL ,TFL, or HGBCL after 2 systemic lines of therapy may have received bridging therapy (dexamethasone 20mg to 40mg, either orally or IV daily for 1 to 4 days or 1g/m\^2 of high-dose methylprednisolone(HDMP) for 3 days with rituximab at 375mg/m\^2 weekly for 3 weeks or bendamustine 90 mg/m\^2 on Days 1 and 2 and rituximab 375mg/m\^2 on Day 1), conditioning chemotherapy (fludarabine 30mg/m\^2 IV and cyclophosphamide 500mg/m\^2 IV)on Days -5,-4, and -3; followed by single infusion of axicabtagene ciloleucel CAR transduced autologous T cells IV at a target dose of 2 x 10\^6 anti-CD19 CAR T cells/kg of BW on Day 0.
