Arms of the Study
Arm 1
Experimental
KTE-C19 + ATZ
Participants will receive conditioning chemotherapy consisting of 30 mg/m^2 fludarabine and 500 mg/m^2 cyclophosphamide intravenous (IV) infusion per day for 3 days followed by KTE-C19 IV infusion at a target dose of 2 x 10^6 anti-CD19 chimeric antigen receptor (CAR) T cells/kg followed by 4 doses of atezolizumab (ATZ) (1200 mg/dose) IV infusion every 21 days. Treatment with ATZ will begin 21 days following KTE-C19 (Phase 1 Cohort 1), 14 days following KTE-C19 (Phase 1 Cohort 2), and 1 day following KTE-C19 (Phase 1, Cohort 3 & Phase 2).
