About this study

The purpose of this study is to assess the antitumor efficacy and safety of perioperative enfortumab vedotin (EV) plus pembrolizumab and radical cystectomy (RC) + pelvic lymph node dissection (PLND) compared with the current standard of care (neoadjuvant chemotherapy \[gemcitabine plus cisplatin\] and RC + PLND) for participants with MIBC who are cisplatin-eligible. The primary hypothesis is perioperative EV and pembrolizumab and RC + PLND (Arm A) will achieve superior event free survival (EFS) compared with neoadjuvant gemcitabine + cisplatin and RC + PLND (Arm B).
