- Primary Outcome Measures
Name Time Method The Number of Participants Experiencing Dose-limiting Toxicities (DLTs): Phase 1B (Dose Finding Stage) From first dose to 28 days after first dose Dose-limiting toxicities (DLTs) are defined as an event that constitute a change from baseline irrespective of outcome and determined by the investigator to be related to treatment. The DLT-evaluable participants were defined as participants who took at least 1 dose of study drug in the Phase 1b Dose-Finding Stage and either had a DLT during Cycle 1 (regardless of amount of study drug exposure), or had no DLT and completed at least 75% of AG-120 or AG-221 doses (21 out of 28 days) and a minimum of 5 doses of AZA, at least 50% of the planned combination doses for AG-120 or AG-221 and AZA administered together (in the same day for 4 out of 7 days) in the first 28 days from C1D1, and were also considered by the Clinical Study Team to have sufficient safety data available to conclude that a DLT did not occur during Cycle 1.
The Number of Participants Experiencing Adverse Events: Phase 1B (Dose Finding and Expansion Stage) From first dose to 28 days after last dose (up to approximately 13 months) The number of participants experiencing different types of adverse events (AE). An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. A Serious Adverse Event (SAE) is any AE occurring at any dose that: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, and/or constitutes an important medical event. Adverse events were analyzed in terms of treatment-emergent AEs (TEAEs). Treatment-emergent adverse events (TEAE) was defined as events that began on or after the start of study drug through 28 days after the last study treatment. The severity/intensity of AEs were graded based upon the Common Terminology Criteria for Adverse Events (CTCAE, Version 4.03) where Grade 3 = Severe, Grade 4 = Life-threatening, and Grade 5 = Death.
Overall Response Rate: Phase 2 (Randomized Stage) From first dose up to approximately 26 months The percent of participants with MLFS + CR + CRi + CRp + PR according to modified International Working Group Acute Myeloid Leukemia (IWG AML) response criteria as assessed by investigator. Complete response (CR) and morphologic leukemia-free state (MLFS) are defined as \<5% blasts in a BM aspirate sample with marrow spicules and a count of ≥200 nucleated cells. There should be no blasts with Auer rods and no extramedullary disease. CR must also include: absolute neutrophil count (ANC) ≥1,000/μL, Platelet count ≥100,000/μL, and independent of red cell transfusions for ≥1 week before each response assessment. Complete remission with incomplete neutrophil recovery (CRi) is all criteria of CR except ANC. Complete remission with incomplete platelet recovery (CRp) is all criteria of CR except platelet count. Partial remission (PR) is defined as all hematologic criteria of CR with a \>50% decrease in the percentage of BM blasts to 5% to 25%. (\<5% considered if Auer rods are present).

Change From Baseline in Visual Analogue Scale (VAS) Scores of the EQ-5D-5L: Phase 2 (Randomized Stage) Baseline and Day 1 Cycle 5 The European Quality of Life 5D-5L (EQ-5D-5L) instrument has a respondent's self-rated today's health scale which is recorded on a VAS with endpoints labeled "the best health you can imagine" and "the worst health you can imagine." The scale is numbered from 0 to 100 with 0 corresponding to the worst imaginable health state and 100 corresponding to the best imaginable health state. A high score represents a better level of QoL.

Subscale scores are transformed to a 0 to 100 scale, with higher scores on functional scales indicating better function and higher scores on symptom scales indicating worse symptoms. Baseline results are obtained just prior to the start of study treatment on Day 1 of Cycle 1 and will serve as the baseline values. EORTC QLQ-C30 is assessed prior to dosing and prior to interaction with study personnel.
Change From Baseline in Health Utility Indices of the EQ-5D-5L: Phase 2 (Randomized Stage) Baseline and Day 1 Cycle 5 The European Quality of Life 5D-5L Scale (EQ-5D-5L) assesses general health-related quality of life. Health is defined in 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses are coded so that a '1' indicates no problem, and '5' indicates the most serious problem. The responses for the 5 dimensions are combined in a 5-digit number. These health states are converted to a single index value using the crosswalk method to the EQ-5D-3L value set from the United Kingdom (UK). The EQ-5D-3L health utility index based on the UK population weights range from -0.594 to 1.0 with higher scores indicating higher health utility. Baseline results are obtained just prior to the start of study treatment on Day 1 of Cycle 1 and will serve as the baseline values.

Progression (PD) is defined as a \> 50% increase of BM blast count percentage from baseline to ≥ 20% for participants with 5 to 70% BM blasts at baseline or a doubling of absolute blast count in peripheral blood from baseline to ≥ 10 x 109/L (10,000/μL) for participants with \> 70% BM blasts at baseline or the development of new extramedullary disease.
