Pembrolizumab (MK-3475) and Bacillus Calmette-Guérin (BCG) as First-Line Treatment for High-Risk T1 Non-Muscle-Invasive Bladder Cancer (NMIBC) and High-Grade Non-Muscle-Invasive Upper Tract Urothelial Carcinoma (NMI-UTUC)] (NCT03504163)

Phase II Study of Pembrolizumab (MK-3475) and Bacillus Calmette-Guérin (BCG) as First-Line Treatment for High-Risk T1 Non-Muscle- Invasive Bladder Cancer (NMIBC) and High- Grade Non-Muscle- Invasive Upper Tract Urothelial Cell Carcinoma (NMI-UTUCC)

🔵 Active, Not Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: Memorial Sloan Kettering Cancer Center

🩺 Plain-English Summary (8th-Grade Level)

The purpose of this study is to find out the effectiveness of pembrolizumab in combination with BCG as a first line therapy for participants with high grade T1 bladder cancer who are at "high risk" for BCG alone to be ineffective and are seeking an alternative treatment option to radical cystectomy. There is biologic rationale for combining pembrolizumab and BCG as two distinct immunotherapies with possible additive or synergistic activity in urothelial cancer. The combination of pembrolizumab with BCG will also be evaluated in an exploratory cohort of patients with upper tract urothelial cancer.
