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).
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).
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).
Andrew Johns, MD, of The University of Texas MD Anderson Cancer Center, discusses efficacy, safety, and tolerability data on tivozanib. The agent yielded a modest clinical benefit in a minority of patients with advanced clear cell renal cell carcinoma who received prior immune checkpoint–based therapies, cabozantinib, and lenvatinib with or without everolimus (Abstract 419).
Umang Swami, MD, of Huntsman Cancer Institute at the University of Utah, describes the molecular and immunologic mechanisms of metastatic tropism in advanced prostate cancer, data that may facilitate future drug development. In patients with metastatic disease, specific sites are associated with differential overall survival, but the biological reasons have not been fully explored (Abstract 21).
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).
