Per-arm endpoint measurements with 95% confidence intervals where reported. Source: trial results section.
Percentage of Participants Experiencing Dose Limiting Toxicities (DLTs)Primary· Group A: Cycle 0 Day 1 to Cycle 2 Day 28; Group B: Cycle 0 Day 1 to Cycle 1 Day 28; Group C: Cycle 1 Day 1 to Cycle 1 Day 28 (Cycle length: for Cycle 0 = 14 days, for all other cycles = 28 days)
DLTs refer to toxicities experienced during the first 28 days of study treatment that have been judged to be clinically significant and related to study treatment. DLT assessment was applicable only for Phase 1b and Phase 2 safety run-in participants.

Percentage of Participants With Morphologic Complete Remission (CR) at the End of InductionPrimary· At the end of induction (Group A: up to end of Cycle 2; Group B: up to end of Cycle 4) (cycle length = up to 28 days); Group C: From Day 1 until meeting the criteria for study treatment discontinuation (up to approximately 3 years)
Clinical response was assessed according to the International Working Group criteria (Cheson 2003). Morphologic CR included CR and cytogenetic CR (CRc). CR required all of the following: \< 5% blasts in bone marrow aspirate; Neutrophils ≥ 1,000/microliter (mcL); Platelets ≥ 100,000/mcL; No extramedullary disease; No blasts with Auer rods detected; and Independent of transfusions. CRc, in addition to CR criteria, required reversion to a normal karyotype with an abnormal karyotype at the time of diagnosis.
