Julie N. Graff, MD, on Castration-Resistant Prostate Cancer: Results From KEYNOTE-199 on Pembrolizumab Plus Enzalutamide
2020 Genitourinary Cancers Symposium
Julie N. Graff, MD, of Oregon Health & Science University and Knight Cancer Institute, discusses study findings that show pembrolizumab plus enzalutamide after progression on enzalutamide produced clinical activity and can lead to durable responses, with a manageable safety profile. The phase III KEYNOTE-641 trial will test patients who are enzalutamide-naive (Abstract 15).
David P. Dearnaley, MD, of The Institute of Cancer Research and Royal Marsden NHS Foundation Trust, discusses 8-year outcomes of the phase III CHHiP trial, which showed that modest hypofractionation is noninferior to conventional fractionation in localized prostate cancer, with no increase in side effects. Disease control was also reported in patients older than age 75 (Abstract 325).
Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, describes a currently recruiting phase III study (COSMIC-313) of cabozantinib in combination with nivolumab and ipilimumab vs nivolumab/ipilimumab for patients with previously untreated advanced renal cell carcinoma of intermediate or poor risk (Abstract TPS767).
Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discusses study results which showed that, in first-line cisplatin-ineligible patients with metastatic urothelial carcinoma, enfortumab vedotin/pembrolizumab demonstrated activity and durability, with a manageable safety profile (Abstract 441).
Thomas Powles, MD, PhD, of Queen Mary University of London, summarizes two papers on metastatic renal cell carcinoma for which he was the discussant: nivolumab in combination with stereotactic body radiotherapy in pretreated patients, and combining dual immune checkpoint inhibition with stereotactic radiation (Abstracts 613 & 614).
Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses findings from a phase I/II trial that found MK-6482 was well tolerated and demonstrated activity in heavily pretreated patients with clear cell renal cell carcinoma (Abstract 611).
