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).
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).
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).
Enrique Grande, MD, of MD Anderson Cancer Center Madrid, discusses findings from the CABATEN/GETNE-T1914 study, in which cabozantinib plus atezolizumab showed modest activity in patients with locally advanced or metastatic adrenocortical carcinoma, a rare malignancy with a poor prognosis and limited therapeutic options. According to Dr. Grande, the existence of long-lasting responders makes it worthwhile to continue investigating predictive factors that may help to select patients for this combination therapy (Abstract 1).
Maha H.A. Hussain, MD, of the Robert H. Lurie Comprehensive Cancer Center, Northwestern University, discusses phase II findings from the BRCAAway trial. This study showed that in patients with metastatic castration-resistant prostate cancer with BRCA1/2 or ATM alterations, abiraterone and prednisone plus olaparib was well tolerated and resulted in a longer progression-free survival than either agent alone or sequentially.
