Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: GEOMETRIC_MEAN
Unit: ng/mL
Interval / dispersion: Geometric Coefficient of Variation
Time frame: Pre-dose, 0.5 hour from start of infusion, 1 hour (at end of infusion) and 2, 3 and 4 hours from start of infusion on Cycle 1/Day 1 and Cycle 1/Day 2

Analysis population: PK concentration population: all treated participants who had at least 1 concentration of any of the study drugs.

Groups in this outcome

Phase 1B: Glasdegib 100 mg + Decitabine

Participants received oral doses of glasdegib tablets 100 mg starting on Day 2 of Cycle 1 for PK assessment purposes and thereafter QD and continuously for 28-day cycles (starting on Day 1 for all other cycles). Decitabine was given at a dose of 20 mg/m\^2 as an intravenous (IV) infusion over 1 hour on Days 1-5 of the 28-day cycles.

Phase 1B: Glasdegib 200 mg + Decitabine

Participants received oral doses of glasdegib tablets 200 mg starting on Day 3 of Cycle 1 for PK assessment purposes and thereafter QD and continuously for 28-day cycles (starting on Day 1 for all other cycles). LDAC was given at a dose of 20 mg subcutaneously BID on Days 1-10 of the 28-day cycles. In March 2013, all active participants receiving glasdegib 200 mg were required to reduce dose to 100 mg. Participants who had glasdegib dose reduction were reported as the starting glasdegib dose level received. Two (2) participants in this cohort had dose reduction to 100 mg starting from Cycle 2/Day 1 and Cycle 2/Day 16, respectively.
