Inclusion criteria

Inclusion criteria: 1. Histological confirmed diagnosis of high risk non-muscle invasive transitional cell carcinoma (TCC) of the urothelium of the urinary bladder (tumors of mixed transitional/non-transitional cell histology are allowed, but TCC must be the predominant histology) 2. Complete resection of all Ta/T1 papillary disease (including participants with concurrent CIS), with most recent positive TURBT occurring within 12 weeks prior to randomization or study intervention. A second TURBT must have been performed if indicated according to the current locally applicable guidelines, ie, American Urological Association, European Association of Urology 3. (Cohorts B1 and B2 only): Histological confirmed diagnosis of BCG-unresponsive high-risk, non-muscle invasive TCC of the urothelium within 12 months (CIS only) or 6 months (recurrent Ta/T1 disease) of completion of adequate BCG therapy. 4. (Cohorts B1 and B2 only): Have refused or are ineligible for radical cystectomy

Exclusion criteria

Exclusion criteria: 1. Evidence of muscle-invasive, locally advanced or metastatic urothelial cancer or concurrent extravesical, non-muscle invasive TCC of the urothelium 2. (Cohort A only): Intravesical BCG therapy within 2 years prior to randomization. Prior intravesical chemotherapy for NMIBC is allowed. 3. (Cohorts B1 and B2 only): Any systemic or intravesical chemotherapy or immunotherapy from the time of most recent positive TURBT to initiation of study intervention. 4. Prior immunotherapy with anti PD-1, anti PD-L1, anti PD-L2, or anti cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody 5. Prior treatment with immunostimulatory agents including interleukin (IL)-2, IL-15, interferon (INF) 6. Prior radiation therapy to the bladder 7. (Cohorts B1 and B2 only): Prior participation in Cohort A of this study.
