          -  Histologically confirmed urothelial cancer by TURBT performed at MSKCC.

          -  TURBT within 6 weeks of protocol entry with complete resection of all papillary
             lesions.

          -  Patients with high risk, BCG-naïve non-muscle-invasive urothelial cancer defined as
             having one of the following disease states:

               -  T1 on restaging biopsy, plus cis

               -  Multiple (≥ 1) T1 recurrences, plus cis

               -  T1b, plus cis

               -  T1 with lymphovascular invasion plus cis

          -  Patient refusal of cystectomy and bilateral pelvic lymphadenectomy

          -  No prior intravesical therapy.

          -  No prior radiation therapy for bladder cancer. Prior radiation therapy for prostate
             cancer is allowed.

             control, be surgically sterile, or abstain from heterosexual activity for the course
             of the study through 120 days after the last dose of the study medication (reference
             section 9.5.2). Subjects of childbearing potential are those who have not been
             surgically sterilized or have not been free from menses for >1 year.

             the first dose of study therapy through 120 days after the last dose of study therapy.

          -  Patients must not have other invasive malignancies within the past 5 years (with the
             exception of non-melanoma skin cancers, localized prostate cancer, and carcinoma in
             situ of the cervix).

             or a documented history of clinically severe autoimmune disease, or a syndrome that
             requires systemic or immunosuppressive agents. Subjects with vitiligo, diabetes Type
             I, or resolved childhood asthma/atopy would be an exception to this rule. Subjects
