• NOTE: The content and format of these specific notifications for the Outside Assay process will vary depending on the designated outside lab in question, as they are each responsible for their own outreach efforts; it is strongly recommended that the designated outside laboratory be contacted to confirm the format and receipt of this notification prior to registering any patients to Step 0
• Patients with an applicable "rare variant" must be able to meet the eligibility criteria for the appropriate subprotocols within 4 weeks following notification of treatment assignment
• NOTE: The receipt of this notification (and the start of the associated deadline for Step 1 registration) may occur shortly after Step 0 registration, since these patients will not be submitting tissue for screening purposes; however, for certain "rare variant" arms, submission of archival tissue for central immunohistochemistry (IHC) testing may be required

1. Disease Status and Prior Therapy: 1. Histologically confirmed AML with >20% blasts 2. Phase 1b: Participants with AML who are refractory to or have relapsed after initial treatment for their disease, with no more than three prior lines of therapy. Participants who have received prior treatment with cytarabine or decitabine are not excluded. 3. Phase 2: i. Participants with AML who are refractory to, or have relapsed after, initial treatment for their disease, with no more than one prior line of therapy, and are judged not to be candidates for re-induction therapy that includes hematopoietic cell transplantation. Participants who have received prior cytarabine or decitabine are not excluded. OR ii. Participants with newly diagnosed, untreated AML ineligible for, or who have refused, standard intensive induction therapy 2. Age ≥18 years 3. ECOG performance status ≤2 4. Participants must be willing and able to review, understand, and provide written consent before starting any study-specific procedures or therapy. 5. All men and women must agree to practice effective contraception during the entire study period and after discontinuing study drug, unless documentation of infertility exists 1. Sexually active, fertile women must use two effective forms of contraception (abstinence, intrauterine device, oral contraceptive, or double barrier device) from the time of informed consent and until at least 6 months after discontinuing study drug 2. Sexually active men and their sexual partners must use effective contraceptive methods from the time of participant informed consent and until at least 3 months after discontinuing study drug 1. Treatment-related AML or acute promyelocytic leukemia (APL) 2. Active malignancies within 12 months with the exception of those with a negligible risk of metastasis or death 3. Clinical evidence of active central nervous system leukemia at the time of screening 4. Alanine aminotransferase and/or aspartate aminotransferase ≥2.5 x upper limit of normal (ULN) 5. Total bilirubin > 2.0 mg/dL (or > 3.0 mg/dL in participants with documented Gilbert syndrome) 6. Serum creatinine ≥2.0 mg/dL 7. New York Heart Association Class III or IV heart disease, active ischemia or any other uncontrolled cardiac condition, or hypertensive or metabolic condition 8. Myocardial infarction in the previous 12 weeks (from the start of treatment) 9. Resting left ventricular ejection fraction <50% at the time of screening 10. QT (Interval from the beginning of the QRS complex to the end of the T wave on an electrocardiogram) interval with Fridericia's correction [QTcF] >450 milliseconds. The QTcF should be calculated as the arithmetic mean of the QTcF on triplicate ECGs. In the case of potentially correctible causes of QT prolongation (e.g., medications, hypokalemia), the triplicate ECG may be repeated once during screening and that result may be used to determine eligibility. 11. Planned concomitant use of medications known to prolong the QT/QTc interval 12. Presence of risk factors for torsade de pointes, including family history of Long QT Syndrome or uncorrected hypokalemia 13. Active and uncontrolled disease (other than AML) or infection as judged by the treating physician 14. Treatment with systemic therapy for the primary disease within 14 days (except for hydroxyurea or isolated doses of cytarabine or decitabine for white blood cell control) 15. Grade 2 or greater toxicities from prior therapy, except for Grade 2 toxicities that are not expected to resolve and that in the judgment of the Investigator do not pose a significant safety risk to subject participation. 16. Participants with any other medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with the participant's ability to sign the informed consent form or his/her ability to cooperate and participate in the study, or to interfere with the interpretation of the results
