Brief Summary:
This is a single center Phase I safety and efficacy study of MK-3475 therapy used in combination with bladder infused BCG treatment for patients, 18 years or older, with high risk superficial bladder cancer (cancer not yet involving the muscle of the bladder wall) who have had removal of their bladder tumor. Patients will be enrolled to a single treatment group of a fixed dose of MK 3475 and BCG.

Condition or disease Intervention/treatment Phase
Bladder Cancer Drug: Intravenous MK-3475/ Intravesical BCG Phase 1

Detailed Description:

Bladder cancer is the fifth most common cancer in the United States. This is a single center Phase I safety and efficacy study of MK-3475 therapy used in combination with bladder infused BCG treatment. The study will determine the safety of administering MK-3475 at a fixed dose every three weeks in conjunction with intravesicular BCG treatment in non-muscle invasive bladder cancer patients who had recurrence after two courses of induction (6 doses) intravesical therapy (two BCG courses, or one BCG course and one other approved intravesical therapies) administered within 12 months, or after one induction (6 doses) and one maintenance (3 doses) intravesical therapy (BCG). Subjects will have confirmation of bladder cancer non-invasive to the muscle. Approximately 20 subjects will be screened to treat 15 eligible subjects with high risk superficial bladder cancer who have had transurethral resection of their bladder tumor.

The rationale for the use of the indicated dose of TICE® BCG is based upon FDA approved and commercially provided package insert/ instructions for use of the product. BCG installation has been used to treat non-muscle-invasive bladder cancer for more than 30 years. It is one of the most successful biotherapies for cancer in use. Despite long clinical experience with BCG, the mechanism of its therapeutic effect is still under investigation.

The first 3 subjects will be treated at a dose of 100 mg MK-3475 to ensure safety for the combination. If no safety or efficacy issues are present, dosing will be escalated to 200 mg MK-3475 every 3 weeks.
