Summary:

      The primary purpose of this research study is to assess whether the participant's disease,
      Myelodysplastic Syndromes (MDS), responds favorably to INCB024360. The study will also
      evaluate the long-term outcomes of the participant's disease after they have finished taking
      INCB024360.
