An Safety and Efficacy Study of Abiraterone Acetate in Participants With Advanced Prostate Cancer Who Failed Androgen Deprivation and Docetaxel-Based Chemotherapy

Completed · Phase 2

Conditions studied: Prostate Neoplasms

In brief

The purpose of this study is to assess the anti-tumor activities and safety of abiraterone acetate in participants with prostate cancer (a disease in which cells in the prostate gland \[a gland in the male reproductive system found below the bladder and in front of the rectum\] become abnormal and start to grow uncontrollably, forming tumors) who have failed taxane (docetaxel)-based chemotherapy.
