Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 148
Healthy volunteers: no

Brief summary:
The purpose of this randomized, blinded, placebo-controlled study was to provide clinical safety and exploratory efficacy data on the use of Eltrombopag in adult subjects with Acute Myeloid Leukemia (AML) receiving standard induction chemotherapy with daunorubicin plus cytarabine. A minimum of 120 evaluable subjects newly diagnosed with AML was stratified by antecedent malignant hematologic disorder and age.

Detailed description:

Arms:
arm 1: Subjects received induction chemotherapy consisting of daunorubicin bolus intravenous (IV) infusion on Days 1-3 + cytarabine continuous IV infusion on Days 1-7 followed by Eltrombopag once daily orally starting on Day 4 of initial induction chemotherapy. If platelet count was not greater than 100 Gi/L after 7 days the dose was increased until a platelet count of at least 200 Gi/L was achieved/until remission was assessed/ maximum of 42 days from the start of the chemotherapy induction. Subjects who were not aplastic after first cycle of induction chemotherapy received second induction chemotherapy with a modified daunorubicin dose on Days 1-3 + cytarabine on Days 1-7. arm 2: Subject received induction chemotherapy consisting of daunorubicin bolus IV infusion on Days 1-3 + cytarabine continuous IV infusion on Days 1-7 followed by matching placebo once daily oral dose starting on Day 4 of initial induction chemotherapy. If platelet count was not greater than 100 Gi/L after 7 days the matching placebo was given until a platelet count of at least 200 Gi/L was achieved/ until remission was assessed/ maximum of 42 days from the start of the chemotherapy induction. Subjects who were not aplastic after first cycle of induction chemotherapy received a second induction chemotherapy with a modified daunorubicin dose on Days 1-3 + cytarabine on Days 1-7.

Interventions: intervention 1: Daunorubicin intervention 2: Cytarabine intervention 3: Eltrombopag intervention 4: Placebo
Intervention descriptions: intervention 1: For subjects between the ages of 18 and 60 years, 90 mg/m2/day by bolus IV injection through a freshly established free-flowing IV line for 10-15 minutes on days 1, 2, and 3. For subjects \> 60 years: daunorubicin dose was adjusted to 60mg /m2. intervention 2: 100 mg/m2/day continuous IV infusion on Days 1 through 7. intervention 3: 200 mg orally, once daily, beginning on Day 4 of the first cycle of induction. After 7 days, the dose of the Investigational Product (IP) was to be increased to 300 mg if platelet counts were \<100 Gi/L. IP continued until achievement of platelet count of at least 200 Gi/L or assessment of remission of bone marrow status or a maximum of 42 days after initiation of most recent induction. In subjects of East Asian heritage 100 mg orally once daily (a 50% dose reduction) was used and after 7 days, the dose of IP was increased to 150 mg if platelet counts were \<100 Gi/L. intervention 4: Orally, once daily, beginning on Day 4 of the first cycle of induction. After 7 days, the dose given was matching 300 mg Eltrombopag if platelet counts were \<100 Gi/L. Placebo continued until achievement of platelet count of at least 200 Gi/L or assessment of remission of bone marrow status or a maximum of 42 days after initiation of most recent induction. In subjects of East Asian heritage placebo matching 100 mg Eltrombopag orally once daily was used and after 7 days, the placebo matching 150 mg Eltrombopag was given if platelet counts were \<100 Gi/L.
