Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To determine the safety and tolerability and recommended phase 2 dose (RP2D) of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase Ib) II. To determine the overall response rate (complete response \[CR\], complete remission with incomplete hematologic recovery \[CRh\], morphologic leukemia-free state \[MLFS\] and partial response \[PR)\] of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase 2)
SECONDARY OBJECTIVES:
I. To determine duration of response (DOR), event-free survival (EFS), and overall survival (OS).
II.To evaluate occurrence of minimal residual disease (MRD) negative status by multiparameter flow cytometry and molecular evaluation.
III. To determine the overall response rate (CR, CRh, Cri, MLFS and PR)
IV. Characterize the pharmacokinetic (PK) profiles of venetoclax in plasma samples (Phase 1b only)
EXPLORATORY OBJECTIVE:
I. To investigate global gene expression profiles, deoxyribonucleic acid (DNA) methylation profiles, BH3 profiling and other potential prognostic markers to explore predictors of antitumor activity and/or resistance to treatment.
OUTLINE: Patients are assigned to 1 of 2 arms.
ARM A: Patients receive decitabine/cedazuridine orally (PO) daily on days 1-5, venetoclax PO daily on days 1-14, and ivosidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive decitabine/cedazuridine PO daily on days 1-5, venetoclax PO daily on days 1-14, and enasidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients (\> 60 year old) with newly diagnosed AML not eligible for intensive chemotherapy are also eligible
* To be considered not eligible for intensive chemotherapy, participants must be defined by the following: Age 75 years or older, or Age 18 to 74 years with at least one of the following comorbidities:
* Severe cardiac disorder (eg, congestive heart failure requiring treatment, ejection fraction ≤50%, or chronic stable angina).
* Severe pulmonary disorder (eg, DLCO ≤65% or forced expiratory volume in 1 second \[FEV1\] ≤65%).
* Creatinine clearance ≥30 mL/min to \<45 mL/min.
* Moderate hepatic impairment with total bilirubin \>1.5 to ≤3.0 × upper limit of normal (ULN)
* ECOG performance status of 2 or 3
* Age \>= 18 years
* Subjects must have documented IDH1 or IDH2 gene mutation
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2
* Adequate renal function including creatinine \< 2 unless related to the disease
* Direct bilirubin \< 2 x upper limit of normal (ULN) unless increase is due to Gilbert's disease or leukemic involvement
* Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) \< 3 x ULN unless considered due to leukemic involvement, in which case direct bilirubin or AST and/or ALT \< 5 x ULN will be considered eligible)
* In the absence of rapidly proliferative disease, the interval from prior treatment to time of initiation will be at least 7 days for cytotoxic or non-cytotoxic (immunotherapy agent(s). Oral hydroxyurea and/or cytarabine (up to 2 g/m\^2) for patients with rapidly proliferative disease is allowed before the start of study therapy, as needed, for clinical benefit and after discussion with the principle investigator (PI). Concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted
* Male subjects who are sexually active with a women of childbearing potential (WOCBP) and who have not had vasectomies must be willing to use a barrier method of contraception and refrain from sperm donation from initial study drug until 90 days after last dose of study drug
* Willing and able to provide informed consent
Exclusion Criteria
* Patients with any concurrent uncontrolled clinically significant medical condition including life-threatening severe infection, or psychiatric illness, which could place the patient at unacceptable risk of study treatment
* Patients with active graft-versus-host-disease (GVHD) status post stem cell transplant (patients without active GVHD on chronic suppressive immunosuppression and/or phototherapy for chronic skin GVHD are permitted after discussion with the PI)
* Patients with any severe gastrointestinal or metabolic condition which could interfere with the absorption of oral study medications
* Corrected QT (QTc) interval using Fridericia's formula (QTcF) \>= 450 msec. Bundle branch block and prolonged QTc interval are permitted after discussion with the PI
* Known active hepatitis B (HBV) or hepatitis C (HCV) infection or known human immunodeficiency virus (HIV) infection
* Subject has a white blood cell count \> 25 x 10\^9/L. (Note: Hydroxyurea is permitted to meet this criterion)
* Nursing women, women of childbearing potential (WOCBP) with positive urine pregnancy test, or women of childbearing potential who are not willing to maintain adequate contraception
* Appropriate highly effective method(s) of contraception include oral or injectable hormonal birth control, intrauterine device (IUD), and double barrier methods (for example a condom in combination with a spermicide)
