Neil E. Fleshner, MD, MPH, on High-Risk Prostate Cancer: New Data on Abiraterone and Cabazitaxel
2022 ASCO Genitourinary Cancers Symposium
Neil E. Fleshner, MD, MPH, of the Princess Margaret Cancer Centre, discusses phase II results from the ACDC-RP trial, which indicate a significant tumor response to neoadjuvant abiraterone acetate plus prednisone and leuprolide, with or without cabazitaxel, in patients with high-risk prostate cancer. Those who exhibited either a complete response or minimal residual disease experienced higher rates of progression-free survival. According to Dr. Fleshner, genomic efforts are underway to determine predictors of response.

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).

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).

Tanya B. Dorff, MD, of City of Hope National Medical Center, discusses the first-in-human phase I findings showing that prostate stem cell antigen (PSCA) CAR T-cell therapy is feasible in patients with metastatic castration-resistant prostate cancer, with preliminary antitumor activity exhibited.

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).

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.
