Overview
Brief Summary
This study has 2 parts: Phase 1A and Phase 1B. The primary objectives of Phase 1A are to evaluate the safety of KITE-439 and to determine a recommended Phase 1B dose. The primary objective of Phase 1B is to estimate the efficacy of KITE-439 in adults who are human leukocyte antigen (HLA)-A*02:01+ and have relapsed/refractory human papillomavirus (HPV)16+ cancers.
