A Study to Assess the Effect of Timing of Food Intake on the Pharmacokinetics of Abiraterone Following Single-Dose Administration of Abiraterone Acetate Tablets in Healthy Caucasian and Japanese Men

9. januar 2014 opdateret af: Janssen Research & Development, LLC

A Single-Dose, Open-Label, Randomized, 4-Way Crossover Study to Assess the Effect of Timing of Food Intake on the Pharmacokinetics of Abiraterone Following Single-Dose Administration of Abiraterone Acetate Tablets in Healthy Caucasian and Japanese Male Subjects

The purpose of this study is to evaluate the effect of timing of food intake on systemic abiraterone exposure observed in healthy adult Japanese and Caucasian men.

Studieoversigt

Detaljeret beskrivelse

This is a randomized (individuals will be assigned by chance to study treatments), open-label (individuals will know the identity of study treatments), single dose, 4-way crossover study of abiraterone acetate in approximately 48 healthy adult Japanese and Caucasian men. For the crossover design, the treatment sequences are defined as follows: 1 - ADBC, 2 - BACD, 3 - CBDA, and 4 - DCAB; where Treatment A = abiraterone acetate administered in the fasted state, Treatment B = standardized meal administered 1 hour after abiraterone acetate dose, Treatment C = standardized meal administered 2 hours after abiraterone acetate dose, and Treatment D = standardized meal administered 2 hours before and 2 hours after abiraterone acetate dose. This study will consist of a screening period followed by four open-label treatment periods separated by a washout period of at least 14 days between dosing. Eligible participants will be randomly assigned on Day 1 to 1 of 4 treatment sequences that differ with regard to timing of food intake before and/or after dosing with a single dose of 1000 mg of abiraterone acetate. Serial pharmacokinetic (study of what the body does to a drug) samples will be collected during the open-label treatment phase as detailed in the protocol. Safety will be monitored throughout the study. End-of-study assessments will be performed on Day 4 of Period 4 or upon early withdrawal.
