Testing the Addition of an Anti-cancer drug, SNDX-5613, to the Standard Chemotherapy Treatment (Daunorubicin and Cytarabine) for Newly Diagnosed Patients with Acute Myeloid Leukemia that has Changes in NPM1 or MLL/KMT2A Gene

Inclusion Criteria

• Induction therapy: Patients ages 18-75 years at time of diagnosis with NPM1-mutated/FLT3-ITD wildtype and NPM1-mutated/FLT3-TKD wildtype or MLL (KMT2A) rearranged untreated AML and who are candidates for intensive induction chemotherapy
• Because no dosing or adverse event data are currently available on the use of SNDX-5613 in combination with daunorubicin and cytarabine in patients < 18 years of age, children are excluded from this study
• Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
• Total bilirubin =< 2 x institutional upper limit of normal (ULN), except for patients with Gilbert’s syndrome
• Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamic pyruvate transaminase [SGPT]) =< 3 x institutional upper limit of normal (ULN)
• Glomerular filtration rate (GFR) >= 60 mL/min/1.73 m^2 (via the Chronic Kidney Disease Epidemiology [CKD-EPI] glomerular filtration rate estimation)
• Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
• For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
• Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
• Ejection fraction >= 50% (or >= 45% if no evidence of congestive heart failure [CHF] or other cardiac symptoms) by transthoracic echocardiogram (TTE) or multi-gated acquisition (MUGA) scan
• White blood cells (WBC) must be < 25 x 10^9/L. Hydroxyurea and leukapheresis are permitted to control the WBC prior to enrollment and initiation of protocol-defined therapy but must be stopped within 24 hours of initiation of protocol therapy. Must not have had any signs of leukostasis requiring cytoreduction
• Female patients of childbearing potential must agree to use 2 forms of contraception from screening visit until 120 days following the last dose of study treatment. Male patients of childbearing potential having intercourse with females of childbearing potential must agree to abstain from heterosexual intercourse or have their partner use 2 forms of contraception from screening visit until 120 days until the last dose of study treatment. They must also refrain from sperm donation from screening visit until 120 days following the last dose of study treatment
• Patients must have previously untreated AML with no prior treatment other than hydroxyurea. No chemotherapy for AML outside of hydroxyurea for treatment of leukostasis or all-trans retinoic acid (ATRA) for initially suspected acute promyelocytic leukemia (APL) (that is ruled out) is allowed
• Ability to understand and the willingness to sign a written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants

Exclusion Criteria

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to SNDX-5613, daunorubicin or cytarabine
• Patients with uncontrolled intercurrent illness that would make participation in this study unduly burdensome or unsafe for patient
• Patient must not have received known strong or moderate CYP3A4 inhibitors, or strong CYP3A4 inducers (with the exception of the antifungal) or sensitive/narrow therapeutic substrates of MATE1 within 7 days of enrollment. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
• Pregnant women are excluded from this study because SNDX-5613 is a menin-KMT2A inhibitor agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with SNDX-5613, breastfeeding should be discontinued if the mother is treated with SNDX-5613. These potential risks may also apply to other agents used in this study
• Isolated myeloid sarcoma (i.e., patients must have blood or marrow involvement with AML to enter the study)
• Acute promyelocytic leukemia (French-American-British [FAB] M3)
• Active central nervous system (CNS) involvement by AML
• Uncontrolled symptomatic disseminated intravascular coagulopathy with active bleeding or signs of thrombosis
• Patients with Fridericia's correction formula (QTcF) >= 450 ms at screening; patients with right, left, or partial bundle branch blocks or a pacemaker who are asymptomatic are eligible regardless of QTC if cleared by cardiology for enrollment in the trial. Any factors that increase the risk of QTc prolongation or risk of arrhythmic event such as congenital long QT syndrome or family history of long QT syndrome
• Patients who will exceed a lifetime anthracycline exposure of > 550 mg/m^2 daunorubicin or equivalent (or > 400 mg/m^2 daunorubicin or equivalent in the event of prior mediastinal radiation) if they receive the maximum potential exposure to anthracyclines per protocol (including both induction and reinduction cycles)
• Patients with any gastrointestinal issue of the upper gastrointestinal (GI) tract that might affect oral drug absorption or ingestion (eg, gastric bypass, gastroparesis, etc)
• Patients who have cirrhosis with a Child-Pugh score of B or C
• Patients with Down Syndrome due to higher rates of chemotherapy-associated toxicities, and may have different pharmacokinetics, as well. Toxicities that occur at higher frequencies include cardiotoxicity, a known risk of SNDX-5613 treatment (i.e., QTcF prolongation)
• Patients with myelodysplastic syndromes (MDS) treated with previous intensive induction regimens similar to 7+3
