What was measured

Dose-limiting toxicities were defined as AEs occurring during this period that meet any of the following criteria, were not related to the primary disease, complication(s), or concomitant medication(s), and has a reasonable relationship with ASTX660. The Common Terminology Criteria for Adverse Events Version 4.03 (CTCAE v4.03) was used to determine severity. 1. Grade 4 thrombocytopenia, Grade 3 or higher clinically significant bleeding, or anemia requiring a new erythrocyte transfusion 2. Febrile neutropenia that does not resolve within 3 days or Grade 4 neutropenia that lasts for more than 7 days under appropriate treatment 3. Liver-associated abnormalities 4. Excepting the above AEs, any other Grade 3 or higher nonhematologic or Grade 4 hematologic toxicity except Grade 3 nausea, vomiting, or diarrhea lasting less than 48 hours

Analysis population: The DLT analysis population include all subjects who received at least 1 dose of IMP and have available data necessary for DLT assessment during the DLT assessment period.

Groups in this outcome

Cohort 1

ASTX660 120mg was orally administered once a day for 7 consecutive days every other week of each 28-day cycle (ie, \[7 days on/ 7 days off\] ×2; daily dosing on Days 1-7 and 15-21).

Cohort 2

ASTX660 150mg was orally administered once a day for 7 consecutive days every other week of each 28-day cycle (ie, \[7 days on/ 7 days off\] ×2; daily dosing on Days 1-7 and 15-21).
