Could a daily pill replace hormone shots for prostate cancer?
NCT ID NCT07299292
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests whether taking abiraterone 250 mg with food and prednisone can lower testosterone to castration levels in prostate cancer patients, without using standard hormone-blocking injections or surgery. The study enrolls 60 men with prostate cancer who need hormone therapy. If it works, it could offer a more convenient, all-oral treatment option.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- abiraterone 250 mg with food plus prednisone
- What this could lead to
- If successful, this could offer a simpler, pill-only option to lower testosterone in prostate cancer patients, avoiding the need for injections or surgery.
- What could go wrong
- This is a small, early-phase trial with only 60 participants. It may not work as well as standard treatments, and abiraterone can cause side effects like high blood pressure or liver issues.
