Axel S. Merseburger, MD, on Prostate Cancer: New Data From the PRESIDE Trial on Enzalutamide, Docetaxel, and Prednisolone
2022 ASCO Genitourinary Cancers Symposium
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).

Hielke-Martijn de Vries, MD, of the Netherlands Cancer Institute, discusses phase II findings on the use of atezolizumab with or without radiotherapy for patients with advanced squamous cell carcinoma of the penis. The study was designed to address the poor prognosis for this disease by exploring whether a protracted schedule of radiotherapy for locoregional disease, in combination with immunotherapy, could improve outcomes (Abstract 3).

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).

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).

Karim Fizazi, PhD, MD, of Gustave Roussy and University of Paris-Saclay, discusses results from a first-in-human phase I/II trial, which showed that administering ODM-208—an oral, nonsteroidal inhibitor of the enzyme CYP11A1—to men with metastatic castration-resistant prostate cancer who were pretreated with abiraterone/enzalutamide and taxanes was effective in blocking the production of steroid hormones. It also showed antitumor activity, especially in men with AR mutation–positive cancers.

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses a 30-month follow-up of results from the KEYNOTE-564 trial, which further support the use of adjuvant pembrolizumab when treating patients with renal cell carcinoma at intermediate-high or high risk of recurrence, or with an M1 NED (no evidence of disease) status after nephrectomy. The data show a disease-free survival benefit vs placebo (Abstract 290).
