NCT ID NCT06173362
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase II trial compares the side effects of two standard treatments for advanced prostate cancer: abiraterone plus prednisone versus darolutamide alone. Researchers will track how many patients experience severe side effects (grade 3 or higher) over the course of treatment. The goal is to help doctors and patients choose the option with fewer serious side effects.
