Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discuses a preliminary phase II analysis of the HIF-2a inhibitor belzutifan in combination with cabozantinib, which showed antitumor activity in previously treated patients with metastatic clear cell renal cell carcinoma (Abstract 272).
A spirited discussion ensued when we asked Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, and Thomas Powles, MD, PhD, of Cancer Research UK Barts Centre, to compare notes on how they treat bladder, prostate, and kidney cancers.
Tracy L. Rose, MD, of the University of North Carolina at Chapel Hill, discusses phase II results of gemcitabine and split-dose cisplatin plus pembrolizumab as neoadjuvant therapy prior to radical cystectomy for patients with muscle-invasive bladder cancer. The trial showed this combination treatment is generally safe and may improve pathologic downstaging, but further study is warranted (Abstract 396).
Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses final results of the phase III TITAN study, which showed apalutamide plus androgen-deprivation therapy improved overall survival, reducing the risk of death up to 48%. This combination treatment also delayed castration resistance and maintained health-related quality of life for patients with metastatic castration-sensitive prostate cancer (Abstract 11).
Felix Y. Feng, MD, of the University of California, San Francisco, discusses study findings showing that molecular determinants may help clinicians select patients with nonmetastatic castration-resistant prostate cancer who may derive the most benefit from apalutamide and other androgen-signaling inhibitors (Abstract 8).
Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, discusses phase III findings from the IPATential150 trial, which showed the effectiveness of ipatasertib plus abiraterone as first-line treatment in patients with metastatic castration-resistant prostate cancer vs placebo plus abiraterone. Analyses of biomarkers linked to the PI3K/AKT pathway, a subtype with a poor prognosis, further support this therapeutic option (Abstract 13).
