A Study of Pembrolizumab (MK-3475) Plus V940 in Participants With Bladder Cancer Post-Radical Resection (V940-005)
The purpose of this study is to assess the safety and efficacy of V940 in combination with pembrolizumab (MK-3475) compared to pembrolizumab alone as an adjuvant treatment for participants with pathologic high-risk muscle-invasive urothelial carcinoma (MIUC) after radical resection. The primary study hypothesis is that V940 in combination with pembrolizumab results in a superior disease-free survival (DFS) as assessed by the investigator compared to pembrolizumab alone in participants with high-risk MIUC after radical resection.
