Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: KITE-222
Dose Escalation: Participants will receive lymphodepleting chemotherapy with cyclophosphamide and fludarabine followed by a single target starting dose of KITE-222 chimeric antigen receptor (CAR) transduced autologous T cells. Based on dose limiting toxicities (DLTs) observed in the first cohort, additional participants will be enrolled and administered escalating dose of KITE-222 to determine the maximum tolerated dose (MTD) of KITE-222. Dose Expansion: Participants will receive lymphodepleting chemotherapy with cyclophosphamide and fludarabine followed by a single dose (at the MTD determined) of KITE-222. |
