Summary
This trial is testing a new way to give abiraterone acetate (a cancer drug) to see if it is safe and effective. It is also looking at why the drug stops working for some people.
Who is the study for?
This trial is for men over 18 with advanced prostate cancer that's resistant to hormone therapy and hasn't spread to the brain. They must have tried other treatments, stopped them at least 4 weeks ago, and still show signs of disease progression. Participants need good heart health, controlled blood pressure without too many medications, normal organ function, no major surgeries or therapies within the last month, and can't be on long-term steroids.
What is being tested?
The study tests if taking abiraterone acetate alone until worsening disease or toxicity symptoms is as safe and effective as taking it with prednisone from the start. It also explores why patients stop responding by analyzing blood and tissue samples.
What are the potential side effects?
Abiraterone acetate may cause high blood pressure, upset stomach, joint swelling or discomfort; liver function changes; increased cholesterol levels; low potassium in the blood; urinary tract infection; or an irregular heartbeat.

Experimental Treatment
Group I: abiraterone acetateExperimental Treatment1 Intervention
Participants will be treated with four 250 mg tablets (1,000 mg) of abiraterone acetate (AA) orally on 28-day cycles. For participants who experience persistent or severe mineralocorticoid excess or have PSA progression, prednisone 5 mg by mouth twice daily will be added.
Patients will be treated until radiographic disease progression and unacceptable AE or taken off study for other reason.
