Healthy Volunteers Clinical Trial
Official title:
An Open-Label Drug-Drug Interaction Study to Assess the Effect of Ketoconazole on the Pharmacokinetics of Abiraterone (JNJ-589485) Following Administration of Abiraterone Acetate (JNJ-212082) Tablets in Healthy Male Subjects
The purpose of this study is to evaluate the pharmacokinetics, safety, and potential for drug-drug interactions when a strong inhibitor of CYP3A4 (ie, ketoconazole) is co-administered with abiraterone acetate in healthy adult men.
This is a non-randomized (individuals will not be assigned by chance to study treatments), open-label (individuals will know the identity of study treatments), 2-period, sequential-design, drug-drug interaction study of abiraterone acetate and ketoconazole in approximately 20 healthy adult men. This study will consist of a screening period followed by an open-label treatment phase consisting of 2 treatment periods. Successive drug administration will be separated by a washout period of at least 10 days. All individuals will receive study treatment in the same sequence. Period 1 (Days 1 to 4) consists of a single oral dose of 1000 mg abiraterone acetate tablets on Day 1 only. Period 2 (Days 11 to 17) consists of a daily oral dose of 400 mg ketoconazole tablets on Days 11 to 16 and administration of a single dose of 1000 mg abiraterone acetate on Day 14. Serial pharmacokinetic (study of what the body does to a drug) samples will be collected at each treatment period as detailed in the protocol. Safety will be monitored continuously from the time of informed consent signing until the end of the study. ;
