TAVT-45 (Abiraterone Acetate) Granules in Patients With Prostate Cancer

This is a Phase 3 randomized, open-label study to evaluate the pharmacodynamic effect and safety profile of TAVT-45 compared to Zytiga (reference abiraterone acetate formulation, hereafter referred to as R-AA) in patients with high-risk metastatic castrate sensitive prostate cancer (mCSPC) and metastatic castrate resistant prostate cancer (mCRPC). Randomization was stratified by prostate cancer population (CSPC vs CRPC) and baseline testosterone (\<10 vs ≥ 10 ng/dL). Patients were treated for 84 days and randomized into one of two groups in a 1:1 ratio: * TAVT-45: Administered twice daily as 1 x sachet containing TAVT-45 (250 mg abiraterone acetate), reconstituted in water or specified fruit juice (orange juice), + Prednisone (5 mg once or twice daily, depending on prostate cancer population) * R-AA: Administered once daily as (2 x 500 mg Zytiga tablets) + Prednisone (5 mg once or twice daily, depending on prostate cancer population)
