Summary:

      Patients with muscle-invasive bladder cancer (MIBC) who can not receive cisplatin or refuse
      cisplatin therapy will receive nivolumab or nivolumab/lirilumab before a planned surgical
      procedure called a radical cystectomy (RC) to remove the bladder.

      Nivolumab works by attaching to and blocking a molecule called Programmed Death-1 (PD-1).
      Lirilumab attaches to and blocks a group of molecules called Killer Cell Immunoglobulin-Like
      Receptor (KIR). PD-1 and KIR are proteins present mainly on immune system cells, and each
      controls part of the immune system by shutting it down. It is hoped that by binding to and
      inactivating these proteins, these drugs can enhance the body's ability to detect, attack and
      destroy cancer cells.

      The purpose of this research study is to see whether nivolumab alone or combination of
      nivolumab and lirilumab given before surgery is effective in treating people who have bladder
      cancer, and to examine the side effects, good and bad, associated with nivolumab and
      lirilumab.
    

Eligibility criteria:

        -  Patients must have histologically confirmed MIBC (T2-T4a, N0-N1, M0 per American Joint
             Commission on Cancer [AJCC]) pure or mixed histology urothelial carcinoma. Clinical
             node-positive (N1) patients are eligible provided the lymph nodes (LNs) are confined
             to the true pelvis and are within the planned surgical LN dissection template.

          -  The most recent TURBT that showed muscularis propria invasion should be within 10
             weeks prior to beginning study therapy. Patients must have sufficient baseline tumor
             tissue from either initial or repeat TURBTs. The local site pathologist will be asked
             to estimate and record the rough approximate percentage of viable tumor in the TURBT
             sample (initial or repeat TURBT with highest tumor content) to document at least 20%
             viable tumor content prior to registration.

          -  Patients must be ineligible for cisplatin-based chemotherapy due to any of the
             following below OR refused cisplatin-based chemotherapy:
