Best Overall Response RateCycle(C)1Day(D)22 and at C2 between D20 and 28 and at C4 and beyond C4 after completion of every 3rd C between D15 and 28 up to 30 days after last dose of study drug/before start of subsequent antineoplastic therapy, if that occurred sooner(up to 5 years)Disease response was based on best overall response as determined by an investigator based on revised recommendations of the International Working Group (IWG) Response Criteria for AML. Best overall response rate was defined as percentage of participants who had complete response (CR), partial response (PR), or CR/remission with incomplete blood count recovery (Cri). CR: free of leukemia-related symptoms, absolute neutrophil count (ANC) greater than (\>)1.0\*10\^9 per liter (/L), platelet count greater than or equal to (\>=) 100\*10\^9/L, normal bone marrow with \<5 percent (%) blasts and no Auer rods. CRi: As per CR but with residual thrombocytopenia (platelet count \<100\*10\^9/L) or residual neutropenia (ANC \<1.0\*10\^9/L). PR: \>=50% decrease bone marrow blasts to 5 to 25% abnormal cells, or CR with less than or equal to (\<=) 5% blasts if Auer rods present.
Duration of ResponseFrom the date of first documented CR, PR or CRi up to the date of first disease progression (Up to 5 years)The duration of response was defined in participants with disease response (CR, CRi, or PR) as the time between the first documentation of response and disease progression. Duration of response was determined by an investigator based on revised recommendations of the IWG Response Criteria for AML. CR: free of leukemia-related symptoms, absolute neutrophil count (ANC) greater than (\>)1.0\*10\^9 per liter (/L), platelet count greater than or equal to (\>=) 100\*10\^9/L, normal bone marrow with \<5 percent (%) blasts and no Auer rods. CRi: As per CR but with residual thrombocytopenia (platelet count \<100\*10\^9/L) or residual neutropenia (ANC \<1.0\*10\^9/L). PR: \>=50% decrease bone marrow blasts to 5 to 25% abnormal cells, or CR with less than or equal to (\<=) 5% blasts if Auer rods present.
Overall SurvivalFrom the first dose of study drug up to date of death (up to 5 years)Overall survival was defined as the time from the first dose of study drug to the date of death. The Kaplan-Meier method was used to estimate overall survival, along with the corresponding 95% confidence interval.

Best Overall Response Rate

Disease response was based on best overall response as determined by an investigator based on revised recommendations of the International Working Group (IWG) Response Criteria for AML. Best overall response rate was defined as percentage of participants who had complete response (CR), partial response (PR), or CR/remission with incomplete blood count recovery (Cri). CR: free of leukemia-related symptoms, absolute neutrophil count (ANC) greater than (\>)1.0\*10\^9 per liter (/L), platelet count greater than or equal to (\>=) 100\*10\^9/L, normal bone marrow with \<5 percent (%) blasts and no Auer rods. CRi: As per CR but with residual thrombocytopenia (platelet count \<100\*10\^9/L) or residual neutropenia (ANC \<1.0\*10\^9/L). PR: \>=50% decrease bone marrow blasts to 5 to 25% abnormal cells, or CR with less than or equal to (\<=) 5% blasts if Auer rods present.

Time frame: Cycle(C)1Day(D)22 and at C2 between D20 and 28 and at C4 and beyond C4 after completion of every 3rd C between D15 and 28 up to 30 days after last dose of study drug/before start of subsequent antineoplastic therapy, if that occurred sooner(up to 5 years)

Population: The response-evaluable population was defined as all participants who received at least 1 dose of study drug, had measurable disease at baseline, and had at least 1 post baseline disease assessment. Participants who were evaluable at a particular time point for this outcome measure were included in the assessment.

Duration of Response

The duration of response was defined in participants with disease response (CR, CRi, or PR) as the time between the first documentation of response and disease progression. Duration of response was determined by an investigator based on revised recommendations of the IWG Response Criteria for AML. CR: free of leukemia-related symptoms, absolute neutrophil count (ANC) greater than (\>)1.0\*10\^9 per liter (/L), platelet count greater than or equal to (\>=) 100\*10\^9/L, normal bone marrow with \<5 percent (%) blasts and no Auer rods. CRi: As per CR but with residual thrombocytopenia (platelet count \<100\*10\^9/L) or residual neutropenia (ANC \<1.0\*10\^9/L). PR: \>=50% decrease bone marrow blasts to 5 to 25% abnormal cells, or CR with less than or equal to (\<=) 5% blasts if Auer rods present.

Time frame: From the date of first documented CR, PR or CRi up to the date of first disease progression (Up to 5 years)

Population: The response-evaluable population was defined as all participants who received at least 1 dose of study drug, had measurable disease at baseline, and had at least 1 post baseline disease assessment.

Overall Survival

Overall survival was defined as the time from the first dose of study drug to the date of death. The Kaplan-Meier method was used to estimate overall survival, along with the corresponding 95% confidence interval.

Time frame: From the first dose of study drug up to date of death (up to 5 years)

Population: The safety population was defined as all enrolled participants who receive at least 1 dose of any study drug, MLN4924 or azacitidine.
