What was measured

Tmax is the time to reach maximum plasma concentration for decitabine. PK parameters for plasma decitabine are reported for the dose confirmation and fixed-dose combination stages.

Analysis population: Participants with evaluable PK measurements are included.

Groups in this outcome

Phase 2 Dose Confirmation

Participants were randomized in a 1:1 ratio to receive either oral cedazuridine (100 mg) + decitabine (35 mg) capsules Dailyx5 in Course 1 followed by IV decitabine (20 mg/m\^2) Dailyx5 in Course 2 (28 days per course) or the converse. In Courses ≥ 3, all participants received cedazuridine and decitabine capsules Dailyx5 in 28-day courses until disease progression, unacceptable toxicity, withdrawal of consent or withdrawal from the study.

Phase 2 Fixed-Dose Combination

Participants were randomized in a 1:1 ratio to receive either the fixed-dose combination (FDC) tablet (100 mg cedazuridine/35 mg decitabine) Dailyx5 in Course 1 followed by IV decitabine (20 mg/m\^2) Dailyx5 in Course 2 (28 days per course) or the converse. In Courses ≥ 3, all participants received the FDC tablet Dailyx5 in 28-day courses until disease progression, unacceptable toxicity, withdrawal of consent or withdrawal from the study.
