All cases have to be histopathologically confirmed by a diagnostic bone marrow biopsy. Use of granulocyte colony-stimulating factor (G-CSF) for any indication must have been discontinued at least 7 days prior to entry into the study.

- No morphological evidence of disease on day 14 bone marrow examination following IC
- Must be able to give voluntary informed written consent to participate in the study; informed consent will be obtained prior to initiation of remission IC and before any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care
Women of childbearing potential should be advised to avoid becoming pregnant and men should be advised to not father a child while receiving treatment. All men and women of childbearing potential must use acceptable methods of birth control throughout the study as described below:
- Females of childbearing potential: Recommendation is for 2 effective contraceptive methods during the study. Adequate forms of contraception are double-barrier methods (condoms with spermicidal jelly or foam and diaphragm with spermicidal jelly or foam), oral, depo provera, or injectable contraceptives, intrauterine devices, and tubal ligation.
- Male patients with female partners who are of childbearing potential: Recommendation is for male and partner to use at least 2 effective contraceptive methods, as described above, during the study or to abstain.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
Exclusion Criteria:

Patients with relapsed or refractory AML will be excluded.
- Radiation therapy, cytotoxic chemotherapy, and combined modality (both radiation and chemotherapy) used to treat other cancers or medical conditions and administered within 12 months prior to signing informed consent. Use of hydroxyurea or emergent leukapheresis (for cytoreduction of highly elevated white blood cell counts) is permissible. Those AML patients who initially receive treatment with all-trans retinoic acid (ATRA) for presumptive diagnosis of APL but if APL is ruled out in final pathology will be eligible for the study.

5. Study Description
Brief Summary
This phase II trial studies how well eltrombopag olamine works in improving the recovery of platelet counts in older patients with Acute Myeloid Leukemia (AML) undergoing induction (the first treatment given for a disease) chemotherapy. Platelet counts recover more slowly in older patients, leading to risk of complications and the delay of post-remission therapy. Eltrombopag olamine may cause the body to make platelets after chemotherapy.
Detailed Description
PRIMARY OBJECTIVES:
I.To determine whether eltrombopag leads to early platelet recovery in older AML patients (≥ 60years) who attain morphologic remission on day 14 (range, day 14-17) bone marrow assessment following remission induction chemotherapy (IC).
SECONDARY OBJECTIVES:
I. To determine the effect of eltrombopag on megakaryopoiesis - median time to reach platelet count ≥50,000 /μL and ≥100,000 /μL, number of days of platelet transfusion, rates of platelet transfusion-independence and the median time to reach platelet transfusion independence.
II. To determine the effect of eltrombopag on the rates of clinically significant bleeding events (CSBE).
III. To determine the effect of eltrombopag on erythropoiesis the median time to red blood cell transfusion independence.
IV. To determine the effect of eltrombopag on granulopoiesis- the time taken to reach an absolute neutrophil count of ≥ 500 /μL. V. To determine the safety and tolerability of eltrombopag in AML patients undergoing remission IC - incidence and severity of eltrombopag-related adverse events. VI. To determine rates of complete remission (CR), rates of partial complete remission (CRp), time to attain CR, and time to initiation of post-remission consolidation therapy.
OUTLINE:
Participants receive eltrombopag olamine orally (PO) once daily (QD) until platelet counts reach ≥50,000/uL or for 8 weeks, whichever comes earlier. Treatment continues in the absence of unacceptable toxicity.
After completion of study treatment, participants are followed up for 2 years.
