* Individuals with histological confirmation of AML by WHO criteria who achieved a CR or CRi with presence of MRD (MRD positive by flow cytometry assay, defined as = 0.1% detectable MRD) after intensive induction chemotherapy with or without consolidation therapy, prior to starting maintenance therapy for newly diagnosed AML, and who are not candidates for hematopoietic stem cell transplantation (SCT) within 1 year of achievement of initial remission
* ECOG performance status of 0 to 2
* Individuals without malabsorption syndrome or other conditions that preclude enteral route of administration

* Current participation in another interventional clinical trial
* Known inherited or acquired bleeding disorders
* Clinical suspicion of or documented active CNS involvement with AML
* Individuals who have acute promyelocytic leukemia

This includes, but is not limited to, acute myocardial infarction within the last 6 months, unstable angina, uncontrolled diabetes mellitus, significant active infections, and congestive heart failure New York Heart Association Class III-IV
* Second malignancy, except MDS, treated basal cell or localized squamous skin carcinomas, localized prostate cancer, or other malignancies for which individuals are not on active anti-cancer therapies and have had no evidence of active malignancy for over 1 year. Previous hormonal therapy with luteinizing hormone-releasing hormone (LHRH) agonists for prostate cancer and treatment with bisphosphonates and receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitors are not criteria for exclusion

* Note: Individuals on maintenance therapy alone who have no evidence of active malignancy for at least = 1 year are eligible.
* Known active or chronic hepatitis B or C infection or human immunodeficiency virus
