• LVEF ≥ 50% by MUGA or ECHO at screening.
• Adequate renal function as demonstrated by a calculated creatinine clearance ≥ 60 mL/min; determined by the Cockcroft Gault formula.
• Adequate liver function as demonstrated by:
• aspartate aminotransferase (AST) ≤ 2.5 × ULN\
• alanine aminotransferase (ALT) ≤ 2.5× ULN\
• total bilirubin ≤ 1.5 × ULN\
• Unless considered due to leukemic organ involvement. Note: Subjects with Gilbert's Syndrome may have a total bilirubin \> 1.5 × ULN per discussion with the Sponsor-Investigator
• Resolution of adverse reactions to prior drug therapy (such as hydroxyurea) to ≤ grade 1
• Eligible for intensive cytarabine/daunorubicin (7+3) chemotherapy based on the opinion of the treating physician.
• Male subjects must agree to refrain from unprotected sex and sperm donation from initial study drug administration until 90 days after the last dose of study drug.
• Females of childbearing potential (i.e., not postmenopausal for at least 1 year or not surgically sterile) must have negative results by a serum or urine pregnancy test performed within 7 days of day 1.
• Ability to understand and the willingness to sign a written informed consent document. (Providing consents in as many languages as possible is encouraged)
• Consolidation should occur between 1-4 weeks following count recovery after induction and remission (must be confirmed by labs to document maximal response) is established. Subjects will receive medium intensity cytarabine -based consolidation in combination with midostaurin and revumenib if the following criteria are fulfilled.
• an induction response \< 5% blasts in the bone marrow and ANC \>1000 and PLT \>75000 for whom documented path report is submitted.
• sufficiently fit (performance status \<3)
• resolution of any adverse reactions to no greater than grade 1 severity

Exclusion criteria

• Subject has acute promyelocytic leukemia, inversion (16), t(8;21) AML as described below. Contact Sponsor-Investigator with questions. Inversion 16 and t(8;21): CBF chromosomal abnormalities may be assessed by molecular (PCR), metaphase cytogenetics, or FISH.
• Subject has known active CNS involvement with AML.
• Subject has received a strong CYP3A4 inducer (APPENDIX C) within 7 days prior to the initiation of study treatment
• Strong CYP3A4 inhibitors (APPENDIX C) are contraindicated except strong CYP3A4 inhibitor antifungal azole medications (systemic itraconazole, ketoconazole, posaconazole, voriconazole). For strong CYP3A4 inhibitor antifungal azole medications, the starting dose of revumenib has to be adjusted (Table 1).
• QTc using Fridericia's correction \[QTcF\]) \> 450 msec. Drugs that prolong QTc should be avoided if possible. A list of common QTc prolonging drugs and alternatives that are not QTc prolonging can be found in APPENDIX D.
• Subject has tested positive for HIV (due to potential drug-drug interaction between antiretroviral medications and Midostaurin/revumenib). Note: HIV testing is not required.
• Subject is known to be positive for hepatitis B or C infection with the exception of those with an undetectable viral load within 3 months. (Hepatitis B or C testing is not required). Subjects with serologic evidence of prior vaccination to HBV \[i.e., HBs Ag-, and antiHBs+\] are allowed.
• Subject has consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or Star fruit within 3 days prior to the initiation of study treatment.
• Subject has a cardiovascular disability status of New York Heart Association Class ≥ 2. Class 2 is defined as cardiac disease in which patients are comfortable at rest but ordinary physical activity results in fatigue, palpitations, dyspnea, or anginal pain.
• Subject has a significant history of renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, hepatic, cardiovascular disease, or any other medical condition that in the opinion of the investigator would adversely affect his/her participating in this study.
• Subject has chronic respiratory disease that requires continuous oxygen use.
• Subject has a malabsorption syndrome or other condition that precludes enteral route of administration.
• Subject exhibits evidence of other clinically significant uncontrolled condition(s) including, but not limited to uncontrolled systemic infection.
• Subject has a history of other malignancies prior to study entry, with the exception of:
• Adequately treated in situ carcinoma of the cervix uteri or carcinoma in situ of breast;
• Basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin;
• Previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
• Prior malignancies treated with (surgery+/- chemotherapy+/- radiation) that have remained disease free for at least two years after completion of therapy
• Subject treated with any form of chemotherapy, immunotherapy, or investigative agent within 1 month of enrollment.
• Patients who have had prior exposure to a menin inhibitor.
