The goal of this clinical research study is to study how effective treatments with clofarabine alone and clofarabine given in combination with ara-C are in the treatment of leukemia and high-risk myelodysplastic syndrome (MDS) in patients who are 60 years or older. The safety of these treatments will also be compared.

Primary Outcome Measures:
  • Number of Participants With Response [ Time Frame: Every 2 to 8 weeks ] [ Designated as safety issue: No ]

    Participant responses are categorized as 'Complete Remission,' Complete Remission, No Platelet Recovery,' 'No Response.'

    Complete Remission: Disappearance of all clinical and/or radiologic evidence of disease. Neutrophil count > 1.0 x 109/L and platelet count > 100 x 109/L, and normal bone marrow differential (< 5% blasts); Complete Remission, No Platelet Recovery: Peripheral blood and bone marrow results as for CR, but with platelet counts of < 100 x 109/L.

    Blood draws once a week until remission then every 2 to 8 weeks during therapy.
