You may be eligible if
Histologically confirmed non-muscle-invasive transitional cell carcinoma (TCC) of the bladder with carcinoma in-situ (CIS)
High-risk NMIBC defined by the following:
BCG-unresponsive NMIBC:
Persistence of high-grade CIS at 6 months following an adequate course of BCG; or Stage/grade progression at 3 months after induction BCG; or Recurrence of high-grade CIS after achieving a disease-free state (i.e., CR) following induction of an adequate course of BCG that occurs less than (\<) 6 months after the last exposure to BCG
BCG-relapsing NMIBC:
Recurrence of high-grade CIS after achieving a disease-free state following induction of an adequate course of BCG that occurs greater than or equal to (\>/=) 6 months after the last exposure to BCG
Very high-risk (VHR) BCG-naïve NMIBC:
VHR NMIBC, defined as having at least 1 of the following: Multiple and/or large (greater than \[\>\] 3 centimeters \[cm\]) T1, (HG/G3) tumors; T1, (HG/G3) tumor with concurrent CIS; T1, G3 with CIS in prostatic urethra; Micropapillary variant of non-muscle invasive urothelial carcinoma
For BCG-unresponsive and BCG-relapsing NMIBC, participants must have received an adequate course of BCG
Resection of all pTa/pT1 papillary disease
No prior radiation to bladder or pelvic region
Eastern Cooperative Oncology Group (ECOG) performance status of less than or equal to (\</=) 2;
Life expectancy \>/=12 weeks
Adequate hematologic and end-organ function
Creatinine clearance \>/=30 milliliters per minute (mL/min) (calculated using the Cockcroft-Gault formula)
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of \<1% per year during the treatment period and for at least 5 months after the last dose of study drug. Women must refrain from donating eggs during this same period.
For men receiving BCG: Agreement to remain abstinent (refrain from sexual intercourse) or use a condom
Tumor tissue biopsy within 60 days prior to study entry or availability of an archival specimen obtained within 60 days of study screening

Administration of a live/attenuated vaccine within 4 weeks prior to the first dose of study treatment, within 5 months following the administration of the last dose of study drug, or anticipation that such a live/attenuated vaccine will be required during the study
History of prior significant toxicity or intolerance to BCG requiring discontinuation of treatment
History of prior systemic BCG infection
History of immunosuppression, or conditions associated with congenital or acquired immune deficiency
Concurrent febrile illness, urinary tract infection, or gross hematuria
Prior treatment with cluster of differentiation 137 (CD137) agonists or immune checkpoint blockade therapies
Treatment with systemic immunostimulatory agents within 6 weeks or five half-lives of the drug, whichever is shorter, prior to the first dose of study treatment
Treatment with systemic immunosuppressive medications within 2 weeks prior to the first dose of study treatment, or anticipated requirement for systemic immunosuppressive medications during the trial
