Circulating Tumor DNA Clearance Is Associated with Response and Survival in Metastatic Urothelial Carcinoma Treated with First-Line Enfortumab Vedotin Plus Pembrolizumab
Background/Objectives: Enfortumab vedotin plus pembrolizumab (EV+pembro) is the standard first-line treatment for metastatic urothelial carcinoma (mUC), yet no validated on-treatment biomarker identifies patients deriving a durable benefit. We evaluated whether circulating tumor DNA (ctDNA) clearance is associated with...
