Overview
This Phase 1 study will assess the safety, tolerability, and preliminary antileukemic activity of ziftomenib in combination with venetoclax and azacitidine (ven/aza), ven, and 7+3 for two different molecularly-defined arms, NPM1-m and KMT2A-r.

Eligibility criteria
Key Inclusion Criteria:
* Patients must have a documented NPM1 mutation or KMT2A rearrangement and have either newly diagnosed or relapsed/refractory AML
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
* Adequate liver, renal, and cardiac function according to protocol defined criteria
* A female of childbearing potential must agree to use adequate contraception from the time of screening through 180 days following the last dose of study intervention. A male of childbearing potential must agree to use abstinence or adequate contraception from the time of screening through 90 days following the last dose of study intervention
Key Exclusion Criteria:
* Diagnosis of either acute promyelocytic leukemia or blast chronic myelomonocytic leukemia
* Known history of BCR-ABL alteration
* Advanced malignant hepatic tumor \[for patients receiving ven/aza combination\]
* Administration of live attenuated vaccines within 14 days prior to, during, or after treatment until B-cell recovery
* Active central nervous system (CNS) involvement by AML.
* Clinical signs/symptoms of leukostasis or WBC \> 25,000 / microliter. Hydroxyurea and/or leukapheresis are permitted to meet this criterion
* Not recovered to Grade ≤1 (NCI-CTCAE v5.0) from all nonhematological toxicities except for alopecia
* Known clinically active human immunodeficiency virus, active hepatitis B or active hepatitis C infection
* For newly diagnosed cohorts: received prior chemotherapy for leukemia, except hydroxyurea and/or leukapheresis to control leukocytosis, prior treatment with all-transretinoic acid for initially suspected acute promyelocytic leukemia, or non-HMA therapy for prior myelodysplastic syndrome
* For relapsed/refractory cohorts: received chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy that is considered to be investigational \< 14 days prior to the first dose of ziftomenib or within 5 drug half-lives prior to the first dose of study drug
* Uncontrolled intercurrent illness including, but not limited to, cardiac illness as defined in the protocol
* Mean corrected QT interval corrected for heart rate by Fredericia's formula (QTcF) \>480 ms on triplicate ECGs
* Uncontrolled infection
* Women who are pregnant or lactating
* An active malignancy and currently receiving chemotherapy for that malignancy or disease that is uncontrolled/progressing
* Patients must have a documented NPM1 mutation or KMT2A rearrangement and have either newly diagnosed or relapsed/refractory AML
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
* Adequate liver, renal, and cardiac function according to protocol defined criteria
