Eligibility criteria: Inclusion Criteria:

1. Age ≥ 18 years.
2. Histologically-confirmed diagnosis of high risk non-muscle-invasive urothelial cell carcinoma of the bladder (mixed histology tumors allowed if urothelial carcinoma histology is \>50%).
3. Fully resected disease at study entry (residual CIS acceptable).
4. BCG-unresponsive high risk non-muscle-invasive bladder cancer after treatment with adequate BCG therapy(at least five times a week during the induction phase and at least two times a week during the maintenance phase).
5. Ineligible for radical cystectomy or refusal of radical cystectomy.
6. Consent to tissue specimen retrieval and testing.
7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

16. Evidence of apparently uncontrolled concomitant disease that may affect compliance with the protocol or interpretation of the results, including significant liver disease (e.g. cirrhosis, uncontrolled major seizures or superior vena cava syndrome).
17. Significant cardiovascular disease, such as New York Heart Association heart attack (class II or higher), myocardial infarction, unstable arrhythmia or unstable angina within 3 months prior to study entry.
18. Patients who have had major surgery within 4 weeks prior to study entry, or who are expected to require major surgery during the course of the study, except diagnostic procedures such as TURBT or biopsy.
19. History of autoimmune diseases, including but not limited to severe muscle weakness, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, angio-thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, dry syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis.
20. History of severe allergy, sensitisation or other hypersensitivity reactions to chimeric or humanised antibodies or fusion proteins.
21. Patients who, in the opinion of the investigator, are otherwise unable to participate in this trial.
