What was measured

Plasma enasidenib 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. Area under the plasma concentration-time curve from time 0 to 24 hours post-dose (AUC0-24) was calculated using the linear trapezoidal rule.

Analysis population: Participants who received enasidenib on Cycle 1 Day 1 or Cycle 2 Day 1 with sufficient data to determine PK parameters. Participants who took less than 80% of their planned continuous dosing regimen were excluded from the analysis of Cycle 2 Day 1.

Groups in this outcome

Phase 2: Enasidenib 100 mg QD

Participants received enasidenib 100 mg QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.
