Adverse Events

Time Frame Adverse events (AEs) were collected from Induction phase Cycle 1, Day 1 up to 35 days after last completed cycle in Consolidation phase, up to approximately 1 year.
Adverse Event Reporting Description A treatment-emergent AE was defined as an AE that emerges (or worsens) from the first dose of study drug and coadministered drugs to the follow-up visit, 35 days after the last dose of study drug and co-administered drugs, or the start date of new acute myeloid leukemia post-treatment, whichever was earlier. The serious AEs (SAEs) reported occurred only in the Induction phase. No SAEs occurred during the consolidation phase. TEAEs at ≥5% are reported for both induction and consolidation phases.
