Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Doctors leading this study plan to collect new information about the lowest effective dose of abiraterone acetate in study participants with prostate cancer who are taking abiraterone in combination with prednisone for the first time. The duration of this study will be about 3 months (12 weeks). How long you stay on abiraterone, and at what dose after completion of the 12 weeks of study drug administration, will be up to you and your treating physician.
