Key clinical point: The addition of bone resorption inhibitors (BRIs) to abiraterone acetate with prednisone prolongs overall survival (OS) in patients with metastatic castration-resistant prostate cancer (CRPC) and bone metastases. The OS was similar regardless of the BRI type used.
Major finding: The median follow-up was 23.5 months. Concomitant use of BRIs was reported in 29.0% of patients. BRI use was associated with OS improvement (31.8 months vs 23.0 months; hazard ratio [HR], 0.65; P less than .001) and shorter time to the first skeletal-related event (32.4 months vs 42.7 months; HR, 1.27; P = .04). Both denosumab and zoledronic acid were associated with similar OS (P = .79).
Study details: A retrospective study of 745 consecutive patients with metastatic CRPC and bone metastases who received abiraterone acetate plus prednisone between 2013 and 2016.
Disclosures: No funding source was reported. The authors received grants, personal fees, travel expenses, and research funding from and/or owned stocks in pharmaceutical companies outside the submitted work.
