A Study to Evaluate the Pharmacokinetics of Abiraterone in Healthy Chinese Male Participants

Overview

The purpose of this study is to evaluate the pharmacokinetics (how the drug concentrations change over time) of abiraterone acetate after oral administration of abiraterone acetate at different dose levels of 250, 500, and 1000 mg in healthy Chinese male participants under fasted conditions.

This is an open-label (all people know the identity of the intervention), randomized (the treatment sequence is assigned by chance), 3-way crossover study (method used to switch participants from one dose level to another in a clinical study) of single doses of abiraterone acetate in healthy Chinese male participants. The study consists of 3 phases: screening, open-label treatment, and follow up phases. After screening, randomly assigned participants will receive different dose levels of abiraterone acetate (Treatment A = 250 mg; Treatment B = 500 mg; and Treatment C = 1000 mg) on Day 1 in each of the 3 treatment periods according to a randomized schedule under fasted conditions (Sequence 1 = ABC; Sequence 2 = BAC; and Sequence 3 = CBA). Each treatment period will be separated by a washout period (period when participant is not receiving any study medication) of at least 7 days. In the follow-up phase, study-related adverse events will be monitored by the investigator. Serial blood samples for pharmacokinetic analysis will be collected and safety will be monitored throughout the study. The total study duration will be approximately 42 days.
