What was measured

ORR was defined as the percentage of participants achieving either a CR or a PR, as assessed by the study investigators using revised IWG Response Criteria for Malignant Lymphoma (Cheson et al, 2007). CR: complete disappearance of all detectable clinical evidence of disease and disease-related symptoms; all lymph nodes and nodal masses must have regressed to normal size; spleen and/or liver must be normal size, not be palpable, and no nodules; bone marrow aspirate and biopsy must show no evidence of disease. PR: a ≥ 50% decrease in SPD of up to 6 of the largest dominant nodes or nodal masses; no increase in size of nodes, liver or spleen and no new sites of disease; multiple splenic and hepatic nodules (if present) must regress by ≥ 50% in the SPD; \> 50% decrease in the greatest transverse diameter for single nodules. 95% CI was calculated by Clopper-Pearson method.

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

Groups in this outcome

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 4

Participants with r/r DLBCL, PMBCL ,TFL, or high-grade B-cell lymphoma (HGBCL) after 2 systemic lines of therapy received optional 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. Participants also received a prophylactic regimen of levetiracetam (750 mg orally or IV twice daily (BID) starting on Day 0). Participants received tocilizumab (initiated on persistent Grade 1 CRS for over 24 hours) and dexamethasone (persistent Grade 1 CRS for over 72 hours and at onset of Grade 1 neurologic toxicity).

Phase 2 (Safety Management Study): Cohort 5

Participants with r/r DLBCL, PMBCL ,TFL, or HGBCL after 2 systemic lines of therapy received debulking therapy (R-CHOP:rituximab 375mg/m\^2 D1,doxorubicin 50mg/m\^2 D1,prednisone 100mg D1 to D5,cyclophosphamide 750mg/m\^2 D1,vincristine 1.4 mg/m\^2 D1 or R-ICE:rituximab 375mg/ m\^2 D1,ifosfamide 5g/m\^2 24h-CI D2,carboplatin AUC5 D2 maximum dose 800mg,etoposide 100 mg/m\^2/day D1 to D3 or R-GEMOX:rituximab 375mg/m\^2 D1,gemcitabine 1000mg/m\^2 D2,oxaliplatin 100mg/m\^2 D2 or R-GDP:rituximab 375mg/m\^2 D1 or D8,gemcitabine 1g/m\^2 D1 \& D8,dexamethasone 40mg D1 to D4,cisplatin 75mg/m\^2 D1(or carboplatin AUC5 D1) or radiotherapy:20 to 30 Gy), 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 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 BID starting on D0).D=Day.

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. Participants also received a prophylactic regimen of levetiracetam (750 mg orally or IV twice daily (BID) starting on Day 0) and corticosteroids (dexamethasone, 10 mg once daily on Days 0, 1, and 2). Participants received tocilizumab (initiated on persistent Grade 1 CRS for over 24 hours) and dexamethasone (persistent Grade 1 CRS for over 72 hours and at onset of Grade 1 neurologic toxicity).
