Fred Saad, MD, on Prostate Cancer: Results From the PROpel Trial on Olaparib and Abiraterone
2022 ASCO Genitourinary Cancers Symposium
Fred Saad, MD, of the University of Montreal Health Centre, discusses phase III findings demonstrating for the first time the clinical benefits of olaparib plus abiraterone in patients with metastatic castration-resistant prostate cancer, irrespective of their homologous recombination repair mutation status. This regimen led to significantly longer radiographic progression-free survival than placebo plus abiraterone (Abstract 11).

Kim Nguyen Chi, MD, of the University of British Columbia, BC Cancer-Vancouver Center, discusses first phase III results from the MAGNITUDE study, which explored the use of the PARP inhibitor niraparib with abiraterone acetate and prednisone as first-line therapy in patients with metastatic castration-resistant prostate cancer with and without homologous recombination repair gene alterations (Abstract 12).

Alicia K. Morgans, MD, MPH, of Dana-Farber Cancer Institute, discusses findings from the largest digital survey conducted in patients with prostate cancer, allowing identification of unmet needs in the patient journey. Preliminary data suggest that lower rates of screening may correlate with higher rates of symptoms at diagnosis and potentially later-stage diagnosis.

Axel S. Merseburger, MD, of the University Hospital Schleswig-Holstein, discusses results from a phase IIIb study of chemotherapy-naive patients with metastatic castration-resistant prostate cancer who have been treated with docetaxel plus prednisolone and experienced disease progression on enzalutamide. The data suggest that continued enzalutamide plus docetaxel improved progression-free survival compared with placebo plus docetaxel (Abstract 15).

Xin Gao, MD, of Massachusetts General Hospital, discusses phase I/II findings on bavdegalutamide, an androgen receptor protein degrader, which showed clinical activity in heavily pretreated patients with metastatic castration-resistant prostate cancer who received one to two prior novel hormonal agents.

Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II findings from the BAYOU trial, which studied durvalumab in combination with olaparib for first-line treatment of platinum-ineligible patients with unresectable, stage IV urothelial carcinoma. Because secondary analyses indicated a potential progression-free survival benefit with this combination, there may be a role for PARP inhibitors in the treatment of advanced disease with homologous recombination repair mutation (Abstract 437).
