What was measured

ORR was defined as the percentage of participants achieving either a complete response (CR) or a partial response (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 sum of the product of the diameters (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% confidence interval (CI) was calculated by Clopper-Pearson method.

Analysis population: The Modified Intent-to-Treat (mITT) analysis set included all participants treated with at least 1.0 x 10\^6 anti-CD19 CAR T cells/kg.

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.
