Study Summary

Multicenter PK study of ASTX727 versus IV decitabine. Adult participants who were candidates to receive IV decitabine were randomized 1:1 to receive the ASTX727 tablet Daily×5 in Cycle 1 followed by IV decitabine 20 mg/m\^2 Daily×5 in Cycle 2, or the converse order. After completion of PK studies during the first 2 treatment cycles, participants continued to receive treatment with ASTX727 from Cycle 3 onward (in 28-day cycles) until disease progression, unacceptable toxicity, or the participants discontinued treatment or withdrew from the study.

Primary Outcome

Total 5-day ASTX727 AUC0-24 exposures were calculated using PK data from 3 days of serial PK sampling, Day 1 AUC0-24 (first ASTX727 dose) was added to (Day 2 AUC0-24+ Day 5 AUC0-24) × 2. Decitabine 5-day AUC0-24 exposures after IV decitabine were calculated as follows: (Day 1 AUC0-24+ Day 5 AUC0-24) / 2 was multiplied by 5. If AUC0-24 on Day 2 (for ASTX727) or Day 1 (IV decitabine) was not available, it was replaced by AUC0-24 on Day 5; the converse was also true.
