Day -3 prior to the single dose of enasidenib and at 0.5, 1, 2, 3, 4, 6, 8, 10, 24, 48, and 72 hours post-dose.

What was measured

The first 3 participants enrolled in each cohort of the dose escalation phase and the first 15 participants enrolled in each arm of Phase 1 Expansion received a single dose of enasidenib three days prior to starting the 28-day dosing regimen (Day -3). AGI-16903 is a primary metabolite of enasidenib. Plasma AGI-16903 was measured using validated liquid chromatography-mass spectrometry methods (LC-MS/MS). The lower limit of quantification (LLOQ) in plasma was 1.00 ng/mL.

Analysis population: Participants who received 1 dose of enasidenib on Day -3 with sufficient data to determine PK parameters. Participants who received 2 doses on Day -3 or who received the incorrect dose were excluded. Participants in the Phase 1 Escalation BID and QD cohorts and Phase 1 Expansion cohorts were were grouped by dose for Day -3 analyses.
