Study Summary

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).

Primary Outcome

EFS is defined as the time from randomization to the first occurrence of following events: radiographic disease progression precluding RC + PLND, failure to undergo surgery in participants with residual disease, gross residual disease left behind at time of surgery, local or distant recurrence based on blinded independent central review (BICR) or death due to any cause.
