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.
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.
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).
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).
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).
Axel Bex, MD, PhD, of The Netherlands Cancer Institute, discusses an efficacy, safety, and biomarker analysis of neoadjuvant avelumab and axitinib in patients with localized renal cell carcinoma who are at high risk of relapse after nephrectomy (Abstract 289).
