Summary:

      The purpose of this study is to evaluate the safety and efficacy of CC-486 in previously
      treated patients with locally advanced or metastatic nasopharyngeal carcinoma having failed
      one to two previous regimens, including platinum-based chemotherapy. Participants will be
      enrolled according to a Simon two-stage design; if the predefined activity is met (>4
      responses [complete response; partial response {CR/PR}] out of the first 17 evaluable
      participants based on independent radiological assessment), then the study will continue to
      enroll an additional 34 participants. If 4 or less responses out of 17 are observed, then the
      study enrollment will be stopped.

        Exclusion Criteria:

          -  History of, or current brain metastasis. Any other malignancy within 5 years prior to
             randomization with the exception of adequately treated in situ carcinoma of the
             cervix, uteri, or non-melanomatous skin cancer (all treatment of which should have
             been completed 6 months prior to enrollment), in situ squamous cell carcinoma of the
             breast, or incidental prostate cancer.

          -  Previous treatment with azacitidine (any formulation), decitabine, any other
             hypomethylating agent.

          -  History of gastrointestinal disorder or defect. Impaired ability to swallow oral
             medication. Persistent diarrhea or malabsorption.

          -  Active cardiac disease and human immunodeficiency virus (HIV) infection

          -  Active bleeding; pathological condition that carries a high risk of bleeding; risk of
             pseudoaneurysm of the internal carotid artery and carotid blowout syndrome.

          -  Major surgery within 14 days prior to starting Investigational Product or has not
             recovered from major side effects.

          -  Another investigational therapy within 28 days or 5 half lives of
             randomization/enrollment, whichever is shorter.

          -  Patient has not recovered from the acute toxic effects of prior anticancer therapy,
             radiation, or major surgery/significant trauma.

          -  Radiotherapy < or = 4 weeks or limited field radiation for palliation < or = 2 weeks
             prior to starting with the investigational product.

          -  Pregnancy/Breast feeding

          -  Any condition that places the patient at unacceptable risk if he/she were to
             participate in the study or that confounds the ability to interpret data from the
             study.
