- ASTX727: Pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24 hours post-dose on Days 1, 2 and 5 of Cycle 1 and 2; Decitabine: Pre-dose, 0.25, 0.5, 1, 1.08, 1.5, 2, 3, 4, 6, 8 hours post-dose on Days 1 and 5 of Cycle 1 and 2 (each cycle= 28 days)
What was measured
Summarized data of t1/2 on Day 1, 2 and 5 respectively for Cycle 1 and 2 has been reported for ASTX727. Similarly, summarized data of t1/2 on Day 1 and 5 respectively for Cycle 1 and 2 has been reported for IV Decitabine.
Analysis population: Overall PK Analysis Set included participants not included in Primary Endpoint PK Analysis Set, received any amount of study treatment, complied with protocol sufficiently to ensure PK samples were collected, provided sufficient samples to measure available plasma concentrations for decitabine. Overall number of participants analyzed:Number of participants evaluable for this outcome measure. Number analyzed:Number of participants evaluable for this outcome measure at specified time point.
Groups in this outcome
MDS or CMML: IV Decitabine
Participants with MDS or CMML received decitabine 20 mg/m\^2 IV injection, once daily, on Days 1 to 5 in cycle 1 or 2 (each cycle = 28 days).
MDS or CMML: ASTX727
Participants with MDS or CMML received ASTX727 tablet, containing the fixed-dose combination of 35 mg decitabine and 100 mg cedazuridine, given by mouth, once daily, on Days 1 to 5 in cycle 1 or 2 (each cycle = 28 days). From cycle 3, participants received ASTX727 tablet, once daily, on Days 1 to 5 of each 28-day cycle until disease progression, unacceptable toxicity, participant discontinued treatment, or was withdrawn from the study.
AML: IV Decitabine
Participants with AML received decitabine 20 mg/m\^2 IV injection, once daily, on Days 1 to 5 in cycle 1 or 2 (each cycle = 28 days).
AML: ASTX727
Participants with AML received ASTX727 tablet, containing the fixed-dose combination of 35 mg decitabine and 100 mg cedazuridine, given by mouth, once daily, on Days 1 to 5 in cycle 1 or 2 (each cycle = 28 days). From cycle 3, participants received ASTX727 tablet, once daily, on Days 1 to 5 of each 28-day cycle until disease progression, unacceptable toxicity, participant discontinued treatment, or was withdrawn from the study.
