Andrea B. Apolo, MD, on Urothelial Carcinoma: Phase III Findings on Pembrolizumab vs Observation
2024 ASCO GU Cancers Symposium
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).
Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses results of the CONTACT-2 trial, which showed cabozantinib plus atezolizumab improved radiographic progression–free survival of patients with metastatic castration-resistant prostate cancer vs a second novel hormonal therapy (NHT) in patients who had experienced disease progression on a prior NHT and have extrapelvic nodal or visceral disease. The benefits were more pronounced in patients with liver metastasis and in those who previously received docetaxel (Abstract 18).
Thomas Powles, MD, of Barts Cancer Institute, Cancer Research UK Experimental Cancer Medicine Centre, and Queen Mary University of London, discusses outcomes reported by patients with previously treated renal cell carcinoma (RCC), taking part in the phase III LITESPARK-005 study. Belzutifan was associated with a prolonged time to deterioration, fewer disease-specific symptoms, and better quality of life compared with everolimus (Abstract 361).
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.
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).
