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).

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).

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).

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).
