Pretreatment Tumor NECTIN4 RNA Expression Is Associated with First-line Enfortumab Vedotin Plus Pembrolizumab Efficacy in Metastatic Urothelial Cancer.
Enfortumab vedotin (EV) + pembrolizumab (P; EV + P) is the preferred first-line standard-of-care treatment for metastatic urothelial carcinoma (mUC), yet predictive biomarkers remain lacking. We retrospectively investigated whether tumor NECTIN4 RNA expression and tumor mutational burden (TMB) are associated with outco...
