Researchers are evaluating the use of olaparib in adult male patients with metastatic castration-resistant prostate cancer (mCRPC) in a real-world setting across multiple centers in France. This observational longitudinal study aims to understand how olaparib is used in treatment sequences, its effectiveness, safety, and patterns of BRCA genetic testing to help improve future clinical care for this condition. The study includes patients who have started olaparib treatment within the last two months before joining the study or who participated in an early access program funded for olaparib use. Treatment decisions are made by the patients' physicians, and researchers observe and collect data without intervening. The study follows patients for up to 24 months from the start of olaparib treatment to track how long they continue the treatment and other outcomes. Participants will be monitored through their routine medical care, and data will be collected on treatment duration, safety, and BRCA testing patterns. The main outcome measured is the time until patients stop olaparib treatment, observed over a period of up to two years. The study relies on patient records and does not involve additional experimental procedures, focusing on real-life treatment experiences and outcomes.
