A Single-Arm Phase II Study of Neoadjuvant Intensified Androgen Deprivation (Leuprolide and Abiraterone Acetate) in Combination With AKT Inhibition (Capivasertib) for High-Risk Localized Prostate Cancer With PTEN Loss

Is NCT05593497 recruiting? Yes, currently enrolling (Sep 2026). This Phase 2 trial studies multiple treatments including Capivasertib and abiraterone acetate for high-risk prostate cancer.

Phase 2RecruitingVA Office of Research and DevelopmentNCT05593497Data as of Sep 2026

Treatment: Capivasertib · abiraterone acetateThe purpose of this study is to learn about how an investigational drug intervention completed before doing prostate surgery (specifically, radical prostatectomy with lymph node dissection) may help in treatment of high risk localized prostate cancers that are most resistant to standard treatments. This is a phase II research study. For this study, capivasertib, the study drug, will be taken with intensified androgen deprivation drugs (iADT; abiraterone and leuprolide) prior to radical prostatectomy. This study drug treatment will be evaluated to see if it is effective in shrinking and destroying prostate cancer tumors prior to surgery and to further evaluate its safety prior to prostate cancer surgery.
