Revised IPSS intermediate risk patients can be considered after discussion with the Investigator. Exclusion Criteria: [Both Stratums] 1. Acute promyelocytic leukemia (APML) M3 subtype of AML. 2. Central nervous system manifestations of AML, unless treated and with no residual manifestations (either by cerebrospinal fluid (CSF) cytology, radiologically or by other clinical assessments) in the last 2 weeks. 3. Evidence or recent history of CNS disease, including primary or metastatic brain tumors, seizure disorders unless there is evidence for clearance of CNS leukemia (2 leukemia free CSFs by morphology and /or flow cytometry 1 week apart). 4. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, cirrhosis, chronic obstructive or restrictive pulmonary disease, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia. 5.
