These patients are eligible as long as they are not greater than 2 months from their last consolidation therapy and will be designated as COHORT 1 (intensive induction cohort) * Patients who have received lower intensity therapy (defined as receiving low-dose cytarabine \[LDAC\] or hypomethylating agent \[HMA\]-based therapy) to achieve remission should have received at least 2 cycles of lower intensity therapy between the time they have achieved CR/CRi and enrollment on this protocol. They will be designated as COHORT 2 (lower intensity induction cohort) * For either subgroup (lower or higher intensity), patients who have measurable residual disease may be enrolled on their respective cohort at any time without maximum 'time from consolidation' requirement * Eastern Cooperative Oncology Group (ECOG) performance status of \< or = 3 * Serum total bilirubin \< or = to 1.5 x the upper limit of normal (ULN) * Serum creatinine \< or = to 2.5 x ULN * Absolute neutrophil count (ANC) \> 0.5 x k/uL * Platelet count \> or = 50 x k/uL * For females of childbearing age, they may participate if they: * Have a negative serum or urine pregnancy test within 10 to 14 days of enrolling * Agree to either abstinence or 2 effective contraceptive methods (such as barrier methods or hormonal contraception) throughout the treatment period and up to 30 days after discontinuing treatment * For male patients with a female partner of childbearing age, they may participate if they agree to either abstinence or 2 effective contraceptive methods throughout the treatment period and up to 30 days after discontinuing treatment * Ability to understand and sign informed consent Exclusion Criteria: * Diagnosis of acute promyelocytic leukemia (APL), AML - M3 by French-American-British (FAB) classification based on morphology, immunophenotype, molecular, or cytogenetics studies * Diagnosis of AML associated t(15;17) or APL variant. Patients with t(9;22) are also ineligible unless they are unable or unwilling to receive therapy with a tyrosine kinase inhibitor * Uncontrolled intercurrent illness including, but not limited to active uncontrolled infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements * Patients with active CNS (central nervous system) disease * Patients with documented hypersensitivity to any components of the study program * Females who are pregnant or lactating or intending to become pregnant during the study * Patients with history of extramedullary AML, except for CNS involvement that is currently controlled, will not be eligible for enrollment * Patient should be removed from current trial if they wish to participate and get treatment on another trial
