---|---|---|---|---|
Primary | Dose-limiting toxicity (DLT) | DLT is defined as an adverse event (AE) that meets protocol defined DLT criteria during cycle 1 (28 days every cycle)and is at least possibly related to study drug. | Up to 28 days after first dose of study drug | |
Primary | Number of Participants With Adverse Events (AEs) | The intensity of each AE was graded from 1 to 5 according to the NCI CTCAE Version 5.0. | From the first dose of the study drug to 30 days after the last dose of study drug | |
Primary | Rate of CR/CRh (complete remission with incomplete hematologic recovery) | CR was defined as < 5% blasts in the bone marrow and full recovery of peripheral blood counts (platelets > 100 x 10^9/L and ANC > 1.0 x 10^9/L); CRh was defined as < 5% blasts in the bone marrow and partial recovery ofperipheral blood counts (platelets > 50 x 10^9/L and ANC > 0.5 x 10^9/L). | From the first dose of study drug to the time of progressive disease, assessed up to 36 months | |
