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.
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).
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).
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.
Petros Grivas, MD, PhD, of the University of Washington and Fred Hutchinson Cancer Research Center, discusses results from Cohort 3 of the TROPHY-U-01 study, which assessed sacituzumab govitecan-hziy in combination with pembrolizumab in patients with metastatic urothelial cancer who experienced disease progression after platinum-based regimens (Abstract 434).
