Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this study is to find out if patients with prostate cancer being treated with the medications abiraterone and prednisone can discontinue hormone injections (examples include leuprolide, goserelin, triptorelin and degarelix). Abiraterone and prednisone are pills used to treat patients with prostate cancer. When abiraterone and prednisone are used, hormone injections are usually continued to maintain a low testosterone level in the blood. This study is being done to find out if testosterone in the blood will stay low while abiraterone and prednisone are used without continued hormone injections.
