Detailed Description

This is an open-label (identity of assigned study drug will be known) study to evaluate safety, efficacy, and pharmacokinetics (study of what the body does to a drug) of decitabine in sequential administration with cytarabine in children with relapsed or refractory AML. The study will determine the maximum tolerated dose of cytarabine that can be given following decitabine (Phase 1) and the response rate to this combination (Phase 2). Participants may enter a continuation phase of single agent-decitabine infusions for as long as such treatment would be considered beneficial. Serial pharmacokinetic samples will be collected and safety and efficacy will be monitored throughout the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Phase 1: Maximum Tolerated Dose (MTD) of Cytarabine
Time Frame: Cycle 1 (42 days)
The maximum tolerated dose (MTD) for cytarabine was based on the number of participants experiencing a dose-limiting toxicity (DLT) by the end of Cycle 1. A non-hematological DLT was defined as: any Grade >=3 toxicity that persists for greater than (>) 5 days or any Grade 2 toxicity that persists for >7 days and that is intolerable to the participant. A hematological DLT was defined as Grade 4 neutropenia or thrombocytopenia due to a hypoplastic bone marrow at Day 42, in the absence of malignant infiltration. The nominal duration of each cycle was 28 days. However, participants who had not experienced bone marrow recovery at Day 28 were followed up to Day 42. Failure of marrow recovery (improvement to Grade 3) by Day 42 was considered a DLT. The maximum duration of Cycle 1 was therefore 42 days.
Cycle 1 (42 days)
Phase 1 and 2: Total Clearance of Decitabine
Time Frame: Cycle 1 (28 days) Day 5: pre-infusion, 0.5 hour during infusion, end of infusion and at 5 minute (min), 0.5 hour, 1 hour, and 2 hour after end of infusion
Total clearance of drug after intravenously administration was calculated as: dose/area under the plasma concentration-time curve.
Cycle 1 (28 days) Day 5: pre-infusion, 0.5 hour during infusion, end of infusion and at 5 minute (min), 0.5 hour, 1 hour, and 2 hour after end of infusion
Phase 1 and 2: Volume of Distribution at Steady-State (Vss) of Decitabine
Time Frame: Cycle 1 (28 days) Day 5: pre-infusion, 0.5 hour during infusion, end of infusion and at 5 min, 0.5 hour, 1 hour, and 2 hour after end of infusion
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug.
Cycle 1 (28 days) Day 5: pre-infusion, 0.5 hour during infusion, end of infusion and at 5 min, 0.5 hour, 1 hour, and 2 hour after end of infusion
Phase 2: Percentage of Participants Who Achieved CR or CRi at Cycle 1 Day 28
Time Frame: Cycle 1 (28 days) Day 28
Response rate (percentage of participants who achieved CR or CRi) was measured using international working group (IWG) criteria. Response rate is defined as complete remission (CR) or complete remission with incomplete blood count recovery (CRi) in children with relapsed or refractory acute myeloid leukemia. CRi is defined as morphologic CR with residual neutropenia (less than [<] 1,000/microliter) or thrombocytopenia <100,000/ microliter). CR is defined as morphologic leukemia-free state, with less than 5 percentage (%) blasts in aspirate sample with marrow spicules and with a count of greater than or equal to (>=) 200 nucleated cells, plus absolute neutrophil count (ANC) greater than (>) 1,000/ microliter, platelet count of >100,000/microliter and participant must be independent of transfusions for a minimum of 1 week before each marrow assessment.
Cycle 1 (28 days) Day 28
Phase 2: Percentage of Participants Who Achieved CR or CRi at Cycle 2 Day 28
Time Frame: Cycle 2 (28 days) Day 28
Response rate (percentage of participants who achieved CR or CRi) was measured using international working group (IWG) criteria. Response rate is defined as complete remission (CR) or complete remission with incomplete blood count recovery (CRi) in children with relapsed or refractory acute myeloid leukemia. CRi is defined as morphologic CR with residual neutropenia (less than [<] 1,000/microliter) or thrombocytopenia <100,000/ microliter). CR is defined as morphologic leukemia-free state, with less than 5 percentage (%) blasts in aspirate sample with marrow spicules and with a count of greater than or equal to (>=) 200 nucleated cells, plus absolute neutrophil count (ANC) greater than (>) 1,000/ microliter, platelet count of >100,000/microliter and participant must be independent of transfusions for a minimum of 1 week before each marrow assessment.
Cycle 2 (28 days) Day 28
Phase 2: Percentage of Participants Who Achieved CR or CRi at End of Study Treatment
Time Frame: End of study treatment (approximately 3 years)
Response rate (percentage of participants who achieved CR or CRi) was measured using international working group (IWG) criteria. Response rate is defined as complete remission (CR) or complete remission with incomplete blood count recovery (CRi) in children with relapsed or refractory acute myeloid leukemia. CRi is defined as morphologic CR with residual neutropenia (less than [<] 1,000/microliter) or thrombocytopenia <100,000/ microliter). CR is defined as morphologic leukemia-free state, with less than 5 percentage (%) blasts in aspirate sample with marrow spicules and with a count of greater than or equal to (>=) 200 nucleated cells, plus absolute neutrophil count (ANC) greater than (>) 1,000/ microliter, platelet count of >100,000/microliter and participant must be independent of transfusions for a minimum of 1 week before each marrow assessment.
End of study treatment (approximately 3 years)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Overall response rate is defined as percentage of participants with complete remission (CR) +complete remission with incomplete blood count recovery (CRi)+partial remission (PR) per IWG Criteria. CRi: morphologic CR with residual neutropenia (less than [<] 1,000/microliter) or thrombocytopenia <100,000/microliter). CR is defined as morphologic leukemia-free state, with less than 5 percentage (%) blasts in aspirate sample with marrow spicules and with a count of greater than or equal to (>=) 200 nucleated cells, plus absolute neutrophil count (ANC) greater than (>) 1,000/ microliter platelet count of >100,000/microliter and participant must be independent of transfusions for a minimum of 1 week before each marrow assessment. PR: all the same hematologic values of a CR, but with a decrease of >=50% of the percentage of blasts to 5% to 25% in the bone marrow aspirate.
Up to approximately 3 years 10 months
Phase 1 and 2: Overall Survival (OS)
Time Frame: From enrollment to death or withdrawal, whichever comes first, for up to approximately 3 years 10 months
OS is defined as the time from the date of first dose of study drug to date of death from any cause. If the participant is alive or the vital status is unknown, the participant will be censored at the date the participant will be last known to be alive.
