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).
Amanda Nizam, MD, of the Cleveland Clinic, discusses results from the UNITE study, which shows patients with advanced urothelial cancer who were treated with enfortumab vedotin-ejfv (EV) after switch maintenance avelumab had outcomes consistent with data with EV in platinum- and immune checkpoint inhibitor–refractory disease (Abstract 537).
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).
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).
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.
