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)]
Sponsor:

Memorial Sloan Kettering Cancer Center

Brief Summary:

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.

Condition or disease

Bladder Cancer

Intervention/treatment

Pembrolizumab (MK-3475)

Bacillus Calmette-Guérin (BCG)

Phase

PHASE2

Detailed Description:

Patients will receive pembrolizumab (MK-3475) administered after TUR in combination with BCG as initial therapy. Pembrolizumab (MK-3475) will be administered as a 400 mg IV infusion at 6-week intervals (Q6W) for 9 doses over a 48 week period, unless there is unacceptable toxicity or other reasons that would warrant the discontinuation of treatment. Patients will receive once-weekly BCG therapy (TICE strain, 50 mg) for 6 consecutive weeks as a standard induction course, given as intravesical BCG for patients with T1 bladder cancer, and administered through a percutaneous nephrostomy tube in antegrade fashion for patients with high-grade NMI-UTUC, consistent with standard clinical practice. BCG will start on week 3 after the first infusion of pembrolizumab (400 mg) to allow for initial priming of T cells to further enhance the effects of BCG treatment. Initiation of induction BCG may be delayed (up to 14 days) if deemed clinically indicated by the treating physician due to side effects from TURBT or ureteroscopy and with permission from the Principal Investigator (PI).
