- Has an active infection requiring systemic therapy
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject’s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial

I. To evaluate the anti-tumor activity of pembrolizumab (MK3475) added to standard chemotherapy and radiation as definitive treatment for patients with cT2-4aN0 muscle-invasive urothelial bladder cancer who are not candidates for or refuse radical cystectomy.
I. Safety as defined by National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0.
II. Complete response (CR) rate in the bladder as assessed by pathologic assessment of exam under anesthesia and transurethral resection of bladder tumor (TURBT) specimen obtained at the completion of all protocol therapy.
III. Metastasis-free survival as assessed by time to the development of radiographic distant metastases from beginning of protocol therapy.
IV. Overall survival as measured by time to death from beginning of protocol therapy.
I. Evaluate PD-1, PD-L1, PD-L2, TIM-3 and VISTA expression in pre and post-treatment tumor samples and correlate to response.
II. Evaluate the type, density and distribution of tumor infiltrating lymphocytes in pre- and post-treatment tumor samples and correlate to response.
III. Evaluate changes in T-cell clonal diversity via T-cell receptor next-generation sequencing and clonotype diversity analysis.
IV. Determine presence of and changes in T-cell responses to common viral and microbial antigens with treatment and correlate to outcomes.
V. Determine the presence of and changes in antibody responses to a broad range of antigens with treatment.
Patients receive a single dose of pembrolizumab intravenously (IV) over 30 minutes and undergo TURBT 2-3 weeks later. After 3-5 weeks, patients receive gemcitabine hydrochloride IV over 30 minutes twice per week for a total of 8 doses, pembrolizumab IV on day 1 once every 3 weeks (Q3W) for 3 doses and external beam radiation therapy (EBRT) on days 1-5 over 4 weeks for a total of 20 fractions. Approximately 12 weeks after completion of radiation, patients undergo TURBT. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 5 years.
