Syed Muneeb Alam, MD, of Memorial Sloan Kettering Cancer Center, discusses study findings evaluating links among microsatellite instability status, tumor mutational burden, and response to immune checkpoint blockade in patients with microsatellite instability–high urothelial carcinoma (Abstract 536).
Rohit K. Jain, MD, MPH, of the H. Lee Moffitt Cancer Center and Research Institute, discusses a novel phase II trial of pembrolizumab plus cabozantinib. The study showed this combination may be efficacious as first-line therapy for patients with metastatic urothelial carcinoma, including those who are ineligible for cisplatin. Further investigation with a focus on predictive biomarkers is ongoing (Abstract 539).
Michiel S. Van Der Heijden, MD, PhD, of the Netherlands Cancer Institute, discusses phase III results from the global EV-302 study, showing that enfortumab vedotin-ejfv plus pembrolizumab improves outcomes in patients with previously untreated locally advanced metastatic urothelial carcinoma compared with chemotherapy. Overall survival benefit was observed across select prespecified subgroups. According to Dr. Van Der Heijden, this immunotherapy combination is a potential new standard of care for first-line locally advanced metastatic urothelial carcinoma (Abstract LBA530).
Thomas Powles, MD, of Barts Cancer Institute, Cancer Research UK Experimental Cancer Medicine Centre, and Queen Mary University of London, discusses overall survival results from the phase III KEYNOTE-564 study of adjuvant pembrolizumab vs placebo in patients with clear cell renal cell carcinoma (Abstract LBA359).
Andrea B. Apolo, MD, of the National Cancer Institute, National Institutes of Health, discusses the results of the AMBASSADOR Alliance A031501 study, which showed adjuvant pembrolizumab improved disease-free survival vs observation for patients with high-risk muscle-invasive urothelial carcinoma after radical surgery. According to Dr. Apolo, the findings support adjuvant pembrolizumab as a new treatment option for this population (Abstract LBA531).
Saby George, MD, of Roswell Park Comprehensive Cancer Center, discusses pharmacokinetics, efficacy, and safety results from CheckMate 67T, a phase III trial comparing the use of subcutaneous vs intravenous nivolumab in patients with advanced or metastatic clear cell renal cell carcinoma who have received prior systemic therapy (Abstract LBA360).
