             described by the protocol prior to study entry, for the duration of pre-operative
             study participation and until definitive hysterectomy/bilateral salpingo-oophorectomy.

             document (or that of legally authorized representative, if applicable).

        Exclusion Criteria:

          -  Radiographic imaging demonstrating uterine cancer that is probably stage I or II.

          -  Prior treatment for endometrial cancer.

          -  Prior treatment with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.

          -  Prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to first dose of
             MK-3475 or has not recovered (i.e., to ≤ grade 1 or baseline) from adverse events due
             to agents administered more than 4 weeks earlier.

          -  Prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2
             weeks prior to the first dose of MK-3475 or has not recovered (i.e., to ≤ grade 1 or
             baseline) from adverse events due to a previously administered agent. Note, subjects
             with ≤ grade 2 neuropathy are an exception to this criterion and may qualify for the
             study. Note, if a subject received major surgery, she must have recovered adequately
             from the toxicity and/or complications from the intervention prior to starting
             therapy.

             live vaccines include, but are not limited to, the following: measles, mumps, rubella,
             varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG),
             and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed
             virus vaccines and are allowed; however, intranasal influenza vaccines (e.g. FluMist)
             are live attenuated vaccines and are not allowed.

             first dose of MK-3475 and any neurologic symptoms have returned to baseline), have no
             evidence of new or enlarging brain metastases, and are not using steroids for at least

             underlying pulmonary disease, or psychiatric illness/social situations that would
             limit compliance with study requirements.

          -  Has an active autoimmune disease that has required systemic treatment in the past 2
             years (i.e. with use of disease modifying agents, corticosteroids, or
             immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or
             physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency,
             etc.) is not considered a form of systemic treatment.
