David H. Aggen, MD, PhD, on Advanced Bladder Cancer: HER2 and PD-L1 Immunohistochemistry and HER2 Genomic Alterations
2024 ASCO GU Cancers Symposium
David H. Aggen, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses reportedly the first data to describe an inverse correlation between HER2 immunohistochemistry expression and PD-L1 combined positive score. According to Dr. Aggen, these and other findings by his team may provide a foundation for further HER2-directed advanced bladder cancer studies (Abstract 538).
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).
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).
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).
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).
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).
