Researchers are conducting a prospective, observational study to describe the real-world clinical experience of patients with metastatic castration-resistant prostate cancer mCRPC treated with a combination of olaparib and abiraterone. The study aims to assess clinical outcomes in patients who are either new to novel hormonal agents NHA-naive or have been previously exposed to these agents before starting olaparib plus abiraterone treatment. Patient demographics, clinical characteristics, and treatments before and after olaparib plus abiraterone will also be documented. Participants will be observed from the start of their olaparib plus abiraterone treatment, with no investigational interventions administered by the study team, reflecting real-world treatment usage. The study plans to enroll patients for up to two years and will follow each patient for one year after the last patient begins treatment. The primary outcome measured is the time to treatment discontinuation within 12 months, along with secondary outcomes such as the time to the first subsequent therapy within 24 months. During the study, participants clinical data, treatment histories, and outcomes will be collected and analyzed. There are no specific study visits or procedures imposed beyond routine clinical care. Safety and treatment adherence will be monitored through observational data. Participants are expected to be involved for the duration of their treatment and follow-up, which may extend to approximately three years from enrollment start to last follow-up.
