Bioequivalence Study of Abiraterone Acetate Coated and Uncoated Tablet Formulations in Healthy Male Participants

The purpose of this study is to determine the bioequivalence (equivalence of pharmacokinetic parameters) of 2 abiraterone acetate coated tablet formulations with respect to the current commercial abiraterone acetate uncoated tablet formulation under fasted (without eating or drinking) conditions in healthy male participants.

This is a Phase 1, randomized (study medication assigned to participants by chance), open-label (all people know the identity of the intervention), single-center, single-dose and 3-way Crossover (the same medications provided to all participants but in different sequence) pivotal study to determine the bioequivalence of 2 abiraterone acetate coated tablet formulations with respect to the current commercial abiraterone acetate uncoated tablet formulation. Approximately 102 healthy male participants will participate in this study. Participants will be randomly assigned to 1 of 6 treatment sequences. The study will consist of 3 parts: Screening Phase (within 21 days before the first study drug administration of the first period), an open-label treatment Phase consisting of 3 single-dose treatment periods (45 days) and follow-up Phase (5 to 7 days after the last study procedure). The total study duration for each participant will be from 45 days to a maximum of 61 days. Participants will receive a single oral 1000 milligram (mg) dose of abiraterone acetate under fasted conditions either as Treatment A (current commercial formulation, uncoated), Treatment B (current commercial formulation, coated) or Treatment C (new composition, coated). Bioequivalence will be primarily evaluated by pharmacokinetic parameters. Participants' safety will be monitored throughout the study.
