Detailed Description
The primary efficacy endpoint was to assess whether dociparstat in conjunction with standard induction therapy for AML increased the complete remission rate based on the International Working Group AML response criteria.
A total of 75 subjects were to be randomized in a 1:1:1 ratio to 1 of the following treatment groups:
- Group 1: cytarabine + idarubicin
- Group 2: cytarabine + idarubicin + dociparstat 0.125 mg/kg/hr
- Group 3: cytarabine + idarubicin + dociparstat 0.25 mg/kg/hr
Subjects received up to 2 induction cycles and up to 2 consolidation cycles and participated in the study for up to 18 months. Clinical laboratory tests were conducted routinely, and bone marrow aspirates and biopsies were performed during the induction cycles. Safety was monitored through adverse events and clinical laboratory results.

Time Frame |
---|---|---|
Number of Subjects Who Achieved Composite Complete Remission

Assessments were performed every 3 months until death or 18 months after the last subject was randomized, whichever occurred first.
|
Randomization until disease relapse or patient death from any cause, whichever occurs first, assessed up to 30 months
|
Number of Subjects Who Achieved Overall Survival
Time Frame: Randomization to end of study (18 months)
|
Overall survival was measured from the date of randomization until death from any cause.
Assessments were performed every 3 months and continued until death or 18 months after the last patient was randomized, whichever came first.
|
Randomization to end of study (18 months)
|
Duration of Morphologic Complete Remission
Time Frame: Randomization to end of study (18 months)
|
The duration of morphologic complete remission was assessed only in subjects who had achieved morphologic complete remission and was defined as the time from achievement of complete response to the detection or relapse. Relapse was defined as the reappearance of leukemia blasts in the peripheral blood, >5% blasts in the bone marrow not attributable to another cause, or appearance/reappearance of extramedullary disease and with a bone marrow blast percentage of >5% but ≤20%. If the latter, a repeat bone marrow examination was performed at least 7 days after the first marrow examination; documentation of the bone marrow blast percentage of >5% was necessary to establish relapse. Assessments were performed every 3 months and continued until death or 18 months after the last subject was randomized, whichever occurred first.
