Experimental: KITE-439
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. |
Drug: KITE-439
A single infusion of E7 T-cell receptor (TCR) T cells (KITE-439) Drug: Cyclophosphamide Administered intravenously Drug: Fludarabine Administered intravenously |
- 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 ]

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Key Inclusion Criteria:
- Advanced cancer defined as relapsed or refractory disease after at least 1 line of therapy that included systemic chemotherapy and that is not amenable to definitive locoregional therapy
- HPV16+ tumor as confirmed by the central laboratory
- HLA type is HLA-A*02:01+ per local assessment
- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
Key Exclusion Criteria:
-
Presence of fungal, bacterial, viral, or other infection requiring anti-microbials for management
- Note: Simple urinary tract infection (UTI) and uncomplicated bacterial pharyngitis are permitted if responding to active treatment and after consultation with the Kite medical monitor
- Primary immunodeficiency
- History of autoimmune disease (eg, Crohns, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years prior to enrollment
- Known history of infection with human immunodeficiency virus (HIV), hepatitis B (HBsAg positive), or hepatitis C (anti-HCV positive). A history of treated hepatitis B or hepatitis C is permitted if the viral load is undetectable per quantitative polymerase chain reaction (qPCR) and/or nucleic acid testing
Note: Other protocol defined Inclusion/Exclusion criteria may apply.
