A Bridging Study of Liposomal Cytarabine-Daunorubicin in Treating Olderly Patients With Treatment-naive High-Risk (Secondary) Acute Myeloid Leukemia

First induction: 100 units/m\^2 by 90-minute IV infusion on Days 1, 3, 5. Second induction: 100 units/m\^2 by 90-minute IV infusion on Days 1 and 3. Consolidation therapy: 65 units/m\^2 by 90-minute IV infusion on Days 1 and 3.

"First induction: 7+3 will be administered as: cytarabine at a dose of 100 mg/m\^2/day on Days 1 through 7 by continuous infusion, and daunorubicin at a dose of 60 mg/m\^2/day on Days 1, 2, and 3.~Second induction: 5+2 will be administered as: cytarabine at a dose of 100 mg/m\^2/day on Days 1 through 5 by continuous infusion and daunorubicin at a dose of 60 mg/m\^2/day on Days 1 and 2.~Consolidation therapy: 5+2 will be administered as: cytarabine at a dose of 100 mg/m\^2/day on Days 1 through 5 by continuous infusion, and daunorubicin at a dose of 60 mg/m\^2/day on Days 1 and 2."
