This pilot phase II trial studies omacetaxine mepesuccinate after cytarabine and daunorubicin hydrochloride, idarubicin, or mitoxantrone hydrochloride in treating older patients with acute myeloid leukemia in first remission (a decrease in or disappearance of signs and symptoms of cancer). Drugs used in chemotherapy, such as omacetaxine mepesuccinate, cytarabine, daunorubicin hydrochloride, idarubicin, and mitoxantrone hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving omacetaxine mepesuccinate after cytarabine and daunorubicin hydrochloride, idarubicin, or mitoxantrone hydrochloride may kill more cancer cells.

PRIMARY OBJECTIVES:
I. To assess the safety and tolerability of delivering omacetaxine mepesuccinate (omacetaxine) for consolidation in adult patients age 55 and older with acute myelogenous leukemia (AML) in first complete remission following induction with chemotherapy.
II. To assess the safety and tolerability of delivering omacetaxine for maintenance in adult patients age 55 and older with acute myelogenous leukemia (AML) in first complete remission following 3 consolidation courses with omacetaxine.
SECONDARY OBJECTIVES:
I. To assess the duration of remission.
II. To evaluate disease-free survival (DFS).
III. To evaluate overall survival (OS).
IV. To assess for minimal residual disease (MRD) during consolidation and maintenance therapy with omacetaxine.
OUTLINE:
INDUCTION THERAPY: Patients receive cytarabine intravenously (IV) continuously daily on days 1-7 and daunorubicin hydrochloride, idarubicin, or mitoxantrone hydrochloride at standard dosing daily on days 1-3. Patients may receive a second induction therapy consisting of cytarabine alone on days 1, 3, and 5 according to standard of care. Patients achieving complete response proceed to consolidation therapy.
CONSOLIDATION THERAPY: Patients receive omacetaxine mepesuccinate subcutaneously (SC) twice daily (BID) on days 1-5. Treatment repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity. Patients achieving continuous remission proceed to maintenance therapy.
MAINTENANCE THERAPY: Patients receive omacetaxine mepesuccinate SC BID on days 1-3. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
