A Study to Evaluate the Effect of Rifampicin on the Pharmacokinetics of Abiraterone in Healthy Male Participants

Healthy Clinical Trial

Official title:
An Open-Label Drug-Drug Interaction Study to Assess the Effect of Rifampicin on the Pharmacokinetics of Abiraterone (JNJ-589485) Following Administration of Abiraterone Acetate (JNJ-212082) Tablets in Healthy Male Subjects

Clinical Trial Summary

The purpose of this study is to assess the effects of repeated daily administration of rifampicin on the pharmacokinetics (what the body does to the medication) of abiraterone following single-dose administration of abiraterone acetate tablets in healthy male participants.

Clinical Trial Description

This is an open-label (all people know the identity of the intervention), single-center (study conducted at one site), 2-period, sequential-design (studies that combine both longitudinal and cross sectional methods), to evaluate the effects of rifampicin on the pharmacokinetics of abiraterone acetate in healthy male participants. The study consists of a screening phase, an open-label treatment phase, and a follow up phase. The screening phase will be within 14 days before the first study medication administration. The treatment phase will consist of 2 treatment periods, Period 1: a single oral dose of abiraterone acetate tablets, and Period 2: a daily oral dose of rifampicin capsules alongwith a single oral dose of abiraterone acetate tablets. The 2 periods will be separated by a washout period of at least 7 days. Blood sample collection for pharmacokinetic assessments will be done for determination of abiraterone and rifampicin concentrations. The follow up phase will be of 14 days. Safety evaluations for adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examinations will be monitored throughout the study. The total study duration will be approximately 31 days. ;
