Stratification factors

• de novo status (de novo AML vs secondary AML)
• geographic region

Inclusion criteria

• {"criterion_text":"- 1.\tBe ≥18 years of age and meet at least 1 of the following criteria defining ineligibility for intensive induction chemotherapy (IC): a.\t≥ 75 years old b.\tECOG PS = 2 c.\tSevere cardiac disorder (eg, congestive heart failure requiring treatment, LVEF ≤50%, or chronic stable angina) d.\tSevere pulmonary disorder (eg, diffusing capacity of the lungs for carbon monoxide ≤65% or forced expiratory volume in 1 second ≤65%) e.\tCreatinine clearance <45 mL/minute f.\tBilirubin >1.5 times upper limit of normal (× ULN) g.\tAny other comorbidity that the Investigator judges to be incompatible with intensive IC must be reviewed and approved by the Medical Monitor before study enrollment."}
• {"criterion_text":"- 10. If female with reproductive potential, must have a negative serum pregnancy test prior to the start of study therapy. Female subjects with reproductive potential are defined as sexually mature women who have not undergone a hysterectomy, bilateral oophorectomy, or tubal occlusion or who have not been naturally postmenopausal for at least 24 consecutive months. Females of reproductive potential, as well as fertile men with female partners of reproductive potential, must use 2 effective forms of contraception (including at least 1 barrier form) from the time of giving informed consent throughout the study and for 90 days (both females and males) following the last dose of study drug(s). Effective forms of contraception are defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal ligation, condoms with spermicide, or male partner sterilization. Coadministration of AG-120 may decrease the concentrations of hormonal contraceptives."}
• {"criterion_text":"- 2.\tHave previously untreated AML, defined according to World Health Organization criteria. Subjects with extramedullary disease alone (ie, no detectable bone marrow and no detectable peripheral blood AML) are not eligible for the study."}

Have an IDH1 mutation resulting in an R132C, R132G, R132H, R132L, or R132S substitution, as determined by central laboratory testing (using an investigational polymerase chain reaction [PCR] assay, Abbott RealTime IDH1) in their bone marrow aspirate (or peripheral blood sample if bone marrow aspirate is not available, with Medical Monitor approval). (Note: Local testing for eligibility and randomization is permitted with Medical Monitor approval; however, results must state an IDH1 mutation resulting in an R132C, R132G, R132H, R132L, or R132S substitution. Bone marrow aspirate [or peripheral blood sample if bone marrow aspirate is not available, with Medical Monitor approval] for central laboratory testing must have been sent with proof of shipment to the central laboratory prior to randomization.)"}

• {"criterion_text":"- 5. Have adequate hepatic function, as evidenced by: a. Serum total bilirubin ≤2 × ULN, unless considered to be due to Gilbert’s disease or underlying leukemia, where it must be <3 × ULN. b. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤3.0 × ULN, unless considered to be due to underlying leukemia."}
• {"criterion_text":"- 6. Have adequate renal function, as evidenced by serum creatinine ≤2.0 × ULN or creatinine clearance >30 mL/min based on the Cockcroft-Gault glomerular filtration rate."}
• {"criterion_text":"- 7. Have agreed to undergo serial blood and bone marrow sampling."}
• {"criterion_text":"- 8. Be able to understand and willing to sign an informed consent form."}
• {"criterion_text":"- 9. Be willing to complete QoL assessments during study treatment and at the designated time points following treatment discontinuation."}

Exclusion criteria

• {"criterion_text":"- 1. Are candidates for intensive IC for their AML."}
• {"criterion_text":"- 10. Have an active, uncontrolled, systemic fungal, bacterial, or viral infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment."}
• {"criterion_text":"- 11. Have a prior history of malignancy other than MDS or myeloproliferative disorder, unless the subject has been free of the disease for ≥1 year prior to the start of study treatment. However, subjects with the following history/concurrent conditions or similar indolent cancer are allowed to participate in the study: a. Basal or squamous cell carcinoma of the skin b. Carcinoma in situ of the cervix c. Carcinoma in situ of the breast d. Incidental histologic finding of prostate cancer"}
• {"criterion_text":"- 12. Have had significant active cardiac disease within 6 months prior to the start of study treatment, including New York Heart Association Class (NYHA) Class III or IV congestive heart failure, myocardial infarction, unstable angina, and/or stroke."}
• {"criterion_text":"- 13. Have a heart-rate corrected QT interval using Fridericia’s method (QTcF) ≥470 msec or any other factor that increases the risk of QT prolongation or arrhythmic events (eg, NYHA Class III or IV congestive heart failure, hypokalemia, family history of long QT interval syndrome). Subjects with prolonged QTcF interval in the setting of bundle branch block may participate in the study."}
• {"criterion_text":"- 14. Have a known infection caused by human immunodeficiency virus or active hepatitis B virus (HBV) or hepatitis C virus that cannot be controlled by treatment."}
• {"criterion_text":"- 15. Have dysphagia, short-gut syndrome, gastroparesis, or any other condition that limits the ingestion or gastrointestinal absorption of orally administered drugs."}
• {"criterion_text":"- 16. Have uncontrolled hypertension (systolic blood pressure [BP] >180 mmHg or diastolic BP >100 mmHg)."}
• {"criterion_text":"- 17. Have clinical symptoms suggestive of active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid during Screening is only required if there is a clinical suspicion of CNS involvement by leukemia during Screening."}

• {"criterion_text":"- 21. Subjects with a known medical history of progressive multifocal leukoencephalopathy."}
• {"criterion_text":"- 3. Have received a hypomethylating agent for myelodysplastic syndrome (MDS)."}
• {"criterion_text":"- 4. Subjects who had previously received treatment for an antecedent hematologic disorder, including investigational agents, may not be randomized until a washout period of at least 5 half lives of the investigational agent has elapsed since the last dose of that agent."}
• {"criterion_text":"- 5. Have received prior treatment with an IDH1 inhibitor."}
• {"criterion_text":"- 6. Have a known hypersensitivity to any of the components of AG-120, matched placebo, or azacitidine."}

Primary endpoints

• {"endpoint_text":"- The primary endpoint of the study is EFS, which is defined as the time from randomization until treatment failure, relapse from remission, or death from any cause, whichever occurs first. Treatment failure is defined as failure to achieve CR by Week 24.","definition_or_measurement_approach":"EFS defined as time from randomization until treatment failure, relapse from remission, or death from any cause; treatment failure = failure to achieve CR by Week 24."}

Secondary endpoints

• {"endpoint_text":"- • CR rate (CR defined as bone marrow blasts <5% and no Auer rods, absence of extramedullary disease, ANC ≥1.0 × 109/L [1000/µL], platelet count ≥100 × 109/L [100,000/µL], and independence of RBC transfusions). • OS, defined as the time from date of randomization to the date of death due to any cause.","definition_or_measurement_approach":"CR rate defined by bone marrow blasts <5%, no Auer rods, absence of extramedullary disease, ANC ≥1.0×109/L, platelets ≥100×109/L, independence from RBC transfusions.

• {"endpoint_text":"- • CR + CRh rate (CRh is defined as a CR with partial recovery of peripheral blood counts where ANC is >0.5 × 109/L [500/µL], and platelet count is >50 × 109/L [50,000/µL]; CRh will be derived by the Sponsor). • ORR, defined as the rate of CR, CRi (including CRp), PR, and MLFS.","definition_or_measurement_approach":"CRh defined as CR with partial peripheral blood recovery: ANC >0.5×109/L and platelets >50×109/L; ORR = rate of CR, CRi (including CRp), PR, and MLFS."}
