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).

Matthew R. Smith, PhD, MD, of Massachusetts General Hospital Cancer Center, discusses overall survival findings from the ARASENS trial, which assessed the efficacy of the androgen receptor inhibitor darolutamide vs placebo in combination with androgen-deprivation therapy and docetaxel for patients with metastatic hormone-sensitive prostate cancer (Abstract 13).

Simon J. Crabb, PhD, MBBS, of the Southampton Experimental Cancer Medicine Centre, discusses data from the ATLANTIS trial, in which the authors hypothesized that switch maintenance therapy with the PARP inhibitor rucaparib, in patients who have derived clinical benefit from first-line chemotherapy, may improve outcomes for those with metastatic urothelial carcinoma that harbored a composite biomarker for DNA repair deficiency (Abstract 436).

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).

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).

Wesley Yip, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II results on neoadjuvant gemcitabine and cisplatin for high-grade upper tract urothelial carcinoma, which was well tolerated and demonstrated a favorable pathologic response rate. Dr. Yip notes that this treatment, given prior to nephroureterectomy, did not significantly delay surgery or increase perioperative complication rates.
