|Actual Study Completion Date :||March 2, 2022|
Phase 1A (Dose Escalation): Participants will receive cyclophosphamide and fludarabine conditioning chemotherapy followed by the investigational treatment, KITE-439.
Phase 1 B: Participants will receive cyclophosphamide and fludarabine conditioning chemotherapy followed by the investigational treatment, KITE-439, at a dose selected based on Phase 1A.
A single infusion of E7 T-cell receptor (TCR) T cells (KITE-439)
- Phase 1A - Percentage of Participants Experiencing Adverse Events Defined as Dose-Limiting Toxicities (DLTs) [ Time Frame: Up to 21 days ]Dose-limiting toxicity is defined as protocol-defined KITE-439 related events with onset within the first 21 days following KITE-439 infusion.
- Phase 1B - Efficacy: Objective Response Rate (ORR) [ Time Frame: Up to 2 years ]ORR is defined as the incidence of a complete response (CR) or a partial response (PR) for participants evaluated by modified Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
- Duration of Response (DOR) [ Time Frame: Up to 2 years ]For participants who experience an objective response, DOR is defined as the time from the date of their first objective response to the date of disease progression per modified RECIST v1.1 or death from any cause.
- Progression-Free Survival (PFS) [ Time Frame: Up to 2 years ]PFS is defined as the time from the KITE-439 infusion date to the date of disease progression per modified RECIST v1.1 or death from any cause.
- Overall Survival [ Time Frame: Up to 15 years ]Overall survival is defined as the time from KITE-439 infusion to the date of death.
- Percentage of Participants Experiencing Adverse Events [ Time Frame: Up to 15 years ]
- Percentage of Participants with Anti-KITE-439 Antibodies [ Time Frame: Up to 2 years ]
- Percentage of Participants with Replication-competent Retrovirus (RCR) [ Time Frame: Up to 15 years ]
- Levels of E7 TCR T Cells [ Time Frame: Up to 2 years ]
