Summary

• No prospective, randomized, head-to-head clinical trials comparing the efficacy and safety of AKEEGA with ERLEADA have been conducted.
• ProBio (Prostate-Biomarker, NCT03903835) is an ongoing, phase 3, outcome-adaptive, multiarm, multiple-assignment, randomized, open-label, international biomarker-driven platform study in patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC) or first-line (L1) metastatic castration-resistant prostate cancer (mCRPC). Patients entering in the mHSPC phase will be randomized to receive either standard of care (SOC) or an experimental treatment including abiraterone acetate, AKEEGA, or ERLEADA based on predefined biomarker signatures. The study has a planned enrollment of 750 patients. The efficacy and safety results have not been published.^1,2
• An ongoing, phase 2, parallel-group, randomized trial evaluating the effectiveness of niraparib and abiraterone acetate, the components of AKEEGA, vs ERLEADA in patients with high-risk localized or locally advanced prostate cancer after SOC radiation therapy has been identified (NCT04947254).³
