Clinical Trial 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.

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.

9.Female subjects of childbearing potential should be willing to use 2 methods of birth control or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication 10.Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

Exclusion Criteria:

1. Currently has active or progressive metastatic disease.

2. Currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment.

3. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.

4. Prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

5. Prior systemic chemotherapy, targeted small molecule therapy, or radiation therapy for bladder cancer.

6. If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.

7. Known additional malignancy that is progressing or requires active treatment.

8. Active autoimmune disease that has required systemic treatment in past 2 years.

9. Has evidence of interstitial lung disease or active, non-infectious pneumonitis.

10. Active infection, including a concurrent febrile illness, requiring systemic therapy.

11. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

12. Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

13. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 4 months after the last dose of trial treatment.

14. Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways) including anti-CD40 and anti-OX40 antibodies.

16. Has known active Hepatitis B (e.g., HBs Ag reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected).

17. Has known active tuberculosis. Subjects will not be specifically tested for the study; however, subjects that are tested within 28 days of beginning study or while on study and test positive with the PPD test before treatment should have active tuberculosis ruled out before therapy begins for their superficial bladder cancer.

18. Has received a live vaccine within 30 days prior to the first dose of trial treatment.

19. Has an active urinary tract infection, gross hematuria, or known broken mucosal barrier of the bladder.

20. Less than 14 days post bladder biopsy, TUR, or traumatic catheterization.

21. Evidence of muscle invasive bladder cancer, or transitional cell carcinoma of the upper urinary tract
