简要总结
A Study in Healthy Male Subjects Designed to Evaluate the Pharmacokinetic Profile of Abiraterone Following Administration of Immediate Release Formulations
详细描述
This was a single centre, 2 part, open-label study in healthy male subjects. Parts 1 and 2 were conducted in separate cohorts of subjects; subjects were not permitted to participate in both parts. Part 1 was a part-randomised, 4 period crossover study planned to include 24 healthy male subjects. Part 2 was a randomised 2-period crossover study in 12 healthy male subjects. The aim was to evaluate the pharmacokinetic profiles of abiraterone following administration of immediate release prototype formulations in healthy male subjects.
