Brief Summary

This is a multi-center Phase II study to determine the safety and efficacy of nivolumab when given in combination with cisplatin and gemcitabine as neoadjuvant treatment in patients with muscle-invasive bladder cancer (MIBC) prior to standard of care radical cystectomy. Patients will receive neoadjuvant treatment with nivolumab in combination with gemcitabine-cisplatin (GC) every 3 weeks for 4 treatment cycles over 12 weeks followed by standard of care radical cystectomy.

Primary Outcomes:

Primary Outcome 1 - Measure: Pathologic Response Rate (PaR) at time of radical cystectomy. PaR is defined as absence of residual MIBC at cystectomy in the surgical specimen (pathologic down-staging to ≤pT1pN0, which includes pT0, pT1,pTa and pTis)

representative to provide written and signed consent prior to the initiation of any
research related procedures.

embedded (FFPE) slides of 5-10 microns in thickness) from TURBT and radical cystectomy
tissues. If archived samples are not available fresh tissue will be used.

Exclusion Criteria:

- Ineligible to receive cisplatin by meeting one or more of the following criteria;

- Creatinine clearance of < 50 mL/min

- Hearing loss of 25 dB at two contiguous frequencies with testing required if a
patient has hearing loss - At the investigator's discretion, and after discussion
with the patient, this exclusion may be waived if the potential benefit of
cisplatin therapy is felt to outweigh the risk of further hearing loss.

- CTCAE v4 Grade 2 or higher peripheral neuropathy,

- New York Heart Association Class III or IV heart failure

- Prior treatment with anti-PD-1, CTLA-4, or anti-PD-L1 therapeutic antibody or
pathway-targeting agents.

need for a major surgical procedure during the course of the study.

sclerosis, systemic vasculitis, or glomerulonephritis.

pneumonia, etc.), or evidence of active pneumonitis on screening chest computed
tomography (CT) scan, history of radiation pneumonitis in the radiation field
(fibrosis) is permitted.

hepatitis B surface antigen [HBsAg] test at screening) or hepatitis C antibody.
Patients with past HBV infection or resolved HBV infection (defined as the presence of
hepatitis B core antibody [HBc Ab] and absence of HBsAg) are eligible. HBV DNA must be
obtained in these patients prior to Cycle 1, Day 1 and confirmed to be negative.
Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase
chain reaction is negative for HCV RNA.

- Active tuberculosis or BCG infection

- Active infection requiring systemic antibiotics for more than 7 days within 3 days

area (BSA) and must be well controlled at baseline and only requiring topical

- Any other chronic medical condition or psychiatric condition, physical examination
finding, or clinical laboratory finding giving reasonable suspicion of a disease or
condition that contraindicates the use of an investigational drug or that may affect
the interpretation of the results or render the patient at high risk from treatment

Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the
skin or in situ cervical cancer that has undergone potentially curative therapy.

for prostate cancer or patients on adjuvant hormonal therapies for breast cancer will
