Study Description

Brief Summary

The purpose of this study is to find out the highest safe dose and examine the side effects and effectiveness of eltrombopag olamine in patients with acute myeloid leukemia (AML) treated with chemotherapy that have not responded to previous therapy or have suffered a relapse

Detailed Description

PRIMARY OBJECTIVES:

To estimate the maximum tolerated dose (MTD) and examine the tolerability of daily oral eltrombopag (eltrombopag olamine) (14 days +/- 2 days after initiation of cytarabine) in patients receiving high dose cytarabine and mitoxantrone for the treatment of acute myeloid leukemia patients with hypoplastic bone marrow 14 days +/- 2 days from initiation of cytarabine.
To examine platelet count recovery to >= 100 x 10^9/L when eltrombopag is administered following high dose cytarabine and mitoxantrone for the treatment of acute myeloid leukemic patients.

OUTLINE: This is a dose-escalation study.

Patients receive eltrombopag olamine orally (PO) once daily (QD) from day 1 up to day 62. Treatment continues for up to 9 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Outcome Measures

Primary Outcome Measures

MTD and tolerability of eltrombopag olamine in patients with AML, determined according to incidence of dose-limiting toxicity (DLT) graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4 [Up to day 15]
Platelet count recovery to >= 100 x 10^9/L when eltrombopag olamine is administered following high dose cytarabine and mitoxantrone for the treatment of AML patients [Up to 9 weeks]

Secondary Outcome Measures

Platelet recovery to >= 100 x 10^9/L and platelet response, assessed based on a modified International Working Group Consensus Criteria for hematologic improvement [Up to 9 weeks]
Number of platelet transfusions and duration of time without platelet transfusions from the first dose of eltrombopag olamine will be measured.
Platelet response based on a modified International Working Group Consensus Criteria for hematologic improvement [Up to 9 weeks]
Platelet transfusion requirements [Up to 9 weeks]

Accepts Healthy Volunteers:

Inclusion Criteria:

Relapsed/refractory AML patients who received standard of care cytarabine and mitoxantrone as their chemotherapy regimen
Patients must either have Grade 4 thrombocytopenia (platelet counts < 25 x 10^9/L) due to chemotherapy unless transfusion within 24-72 hours
Current systemic treatment for AML, with the exception of granulocyte colony-stimulating factor (G-CSF) must have been discontinued at least 7 days prior to entry into the study; in addition:
At least 4 weeks before Day 1 for interleukin (IL)-11 (oprelvekin)
At least 8 weeks before Day 1 for antithymocyte/antilymphocyte globulin
Patients with a prior stem cell transplant (SCT) must have failed the SCT
