• FOR PATIENTS IN STAGE 1 (PATIENTS #1-#17)
• >= 55 years of age with AML of any risk classification, or 18-54 years of age with high-risk AML disease based on one of the following: * Antecedent hematologic disorder including myelodysplasia (MDS)-related AML (MDS/AML) and prior myeloproliferative disorder (MPD) * Treatment-related myeloid neoplasms (t-AML/t-MDS) * AML with FLT3-ITD * Myeloid sarcoma * AML with multilineage dysplasia (AML-MLD) * Adverse cytogenetics (defined as -5/-5q; -7/-7q; abnormal 3q, 9q, 11q, 20q, 21q or 17p; t(6;9); t(9;22); trisomy 8; trisomy 13; trisomy 21; complex karyotypes (>= 3 clonal abnormalities); monosomal karyotypes
• FOR PATIENTS IN STAGE 2 (ENROLLED PATIENT #18 AND BEYOND)
• >= 55 years of age with AML of any risk classification, or 18-54 years of age with intermediate or high risk AML as defined by National Comprehensive Cancer Network (NCCN) risk assignment

Exclusion Criteria

• STAGE I
• Patients 18-54 years of age with “good risk” AML defined as the presence of t(8;21), inv(16), or t(16;16) as diagnosed by morphologic criteria, flow cytometric characteristics, and rapid cytogenetics or fluorescence in situ hybridization (FISH) (patients with t(8;21), inv(16), t(16;16) who are unable to receive anthracycline based induction will be allowed to enroll provided the medical reason they are unable to receive anthracyclines is clearly documented and provided they fulfill all other eligibility and criteria)
• STAGES 1 AND 2
• Patients with acute promyelocytic leukemia (APL) as diagnosed by morphologic criteria, flow cytometric characteristics, and rapid cytogenetics or FISH or molecular testing
• Any previous treatment with vosaroxin
• Concomitant chemotherapy, radiation therapy * For patients with hyperleukocytosis with > 50,000 blasts/uL; leukapheresis or hydroxyurea may be used prior to study drug administration for cytoreduction at the discretion of the treating physician; hydroxyurea must be stopped 24 hours prior to initiation of protocol defined therapy
• Active central nervous system (CNS) leukemia
• Active, uncontrolled infection; patients with infection under active treatment and controlled with antibiotics are eligible
• Active, uncontrolled graft vs. host disease (GVHD) following allogeneic transplant for non-AML condition (e.g. MDS, lymphoid malignancy, aplastic anemia); patients with GVHD controlled on stable doses of immunosuppressants are eligible
• Known human immunodeficiency virus (HIV) seropositivity
• Any other medical, psychological, or social condition that may interfere with study participation or compliance, or compromise patient safety in the opinion of the investigator or medical monitor
• Left ventricular ejection fraction (LVEF) < 40% as measured by echocardiogram or multi gated acquisition scan (MUGA)
• Women who are pregnant or breastfeeding
• Renal insufficiency requiring hemodialysis or peritoneal dialysis
