  Outcome Measures

1.  Primary:   Response Rate (Complete Response [CR] Plus Partial Response [PR]) of Clofarabine Plus Cytarabine in Patients With Relapsed/Refractory AML, Untreated MDS, CML in Blast Phase, or in Selected Untreated Patients With High Risk of Anthracycline Toxicity   [ Time Frame: Proportion of confirmed responses was estimated by the number of patients who achieved a CR or PR, defined as two consecutive evaluations at least 4 weeks apart, divided by the number of eligible participants in the study. ]

2.  Secondary:   Number of Participants Who Had an Adverse Event While on Treatment With Clofarabine Plus Cytarabine   [ Time Frame: Up to five months (includes follow up period of 30 days) from the day patient received their first dose of study drug ]
