Title: Phase I Study of Eltrombopag for Promoting Thrombopoiesis in Patients Undergoing Stem Cell Transplantation After Total Body Irradiation
Brief Summary: Patients who undergo total body irradiation (TBI) for stem cell transplantation have prolonged periods of low counts of specific blood cells called platelets. These low platelets counts can cause bleeding and infection. Thus far, no drug is available for use to speed the recovery of platelets, and therefore transfusions are often necessary.

The purpose of this study is to test the safety of a drug called eltrombopag in patients who have received TBI. The investigators want to find out what effects, good or bad, it has on people with low platelet counts due to treatment with TBI. The investigators will also be testing how well eltrombopag may work at different doses and determine if this drug speeds up the recovery of the platelets.


Options:
A: Inclusion Criteria:

1. Healthy subjects with no clinically significant abnormality identified by physician by evaluation of medical history, physical examination, clinical laboratory tests or electrocardiogram (ECG).
2. Male and female subjects between the ages of 18 to 64 years of age inclusive, at the time of signing the informed consent.
3. Subject is able to understand and comply with the protocol requirements, instructions and restrictions.
4. Capable of giving written informed consent which includes compliance with the requirements and restrictions listed in the consent form.
5. Body weight ≥ 50kg (110 lbs) for men and ≥ 45 kg (99 lbs) for women and body mass index (BMI) of 18.5 to 29.9 kg/m2 inclusive.
6. A platelet count within normal range and not \> 400,000 plt/uL.
7. Male subjects, who are not surgically sterile, must agree on abstinence or to use a double barrier method, such as, a condom plus spermicidal agent (foam/gel/film/cream/suppository). This criterion must be followed from the time of the first dose of study medication until 14 days after the last dose of medication.
8. A female subject is eligible to participate if she is neither pregnant nor lactating, and falls into one of the following categories:

   * non-childbearing potential including pre-menopausal females with documented (medical report verification) hysterectomy or bilateral oophorectomy, or post-menopausal females defined as being amenorrheic for greater than one year and having serum estradiol and follicle stimulating hormone levels consistent with menopause.
   * child-bearing potential with negative beta human chorionic gonadotropin (beta/hCG) test and agrees to comply with recognized non-hormonal contraceptive methods from screening or at least two weeks prior to first dose (whichever is earlier) until the follow-up visit. Recognized non-hormonal contraceptive methods include: complete abstinence from intercourse, male partner sterilization, two forms of barrier contraception (e.g. condom and occlusive cap (diaphragm or cervical/vault caps with spermicide), or intrauterine device (IUD), or intrauterine system (IUS) with a \< 1% failure rate stated in the product label.

Exclusion Criteria:

1. History of Gilbert's syndrome.
2. Any previous history of deep vein thrombosis or any other thromboembolic event.
3. History of thrombocytopenia or bleeding due to abnormal platelet number or function.

5. Elevated blood pressure (BP) at screening (systolic \> 140 mm Hg, diastolic \> 85 mm Hg). If the subject's BP is elevated on the first measurement, complete two additional BP measurements two minutes apart and average the three assessments to evaluate this criteria. If averaged BP exceeds the safety criteria, the subject should be excluded.
6. History of atrial fibrillation, mitral valve prolapse, significant heart murmur or vascular bruit.
7. Prolonged QTc interval (Bazett's) at screening (for females \> 450 msec and for males \> 430 msec). If the QTc interval is prolonged on the initial ECG, then complete two additional ECGs 5 minutes apart and take the average QTc measurements of all three ECGs to evaluate this criteria. If averaged QTc exceeds the safety criteria, the subject should be excluded.
8. Female subjects currently receiving hormone replacement therapy (HRT).
9. Positive for HIV, hepatitis B virus or hepatitis C virus assays at screening.
10. Positive urine drug screen including alcohol at screening or pre-dose (Day -1).
11. History of alcohol/drug abuse or dependence within 12 months of the study.
12. History of alcohol consumption in the past six months exceeding 7 units/week for women and 14 units/week for men (where 1 unit = 5 ounces of wine or 12 ounces of beer or 1.5 ounces of hard liquor).
13. Urinary cotinine levels indicative of smoking at screening or pre-dose (Day -1). History of regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
14. Treatment with an investigational drug within 30 days or five half-lives (whichever is longer) preceding the first dose of study medication.
15. Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
16. Use of prescription or non-prescription drugs (including aspirin and non-steroidal anti-inflammatory drugs \[NSAIDs\]), vitamins, herbal and dietary supplements within seven days (or 14 days if the drug is a potential enzyme inducer, such as St. John's Wort) or five half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the investigator and sponsor the medication will not interfere with the study procedures or compromise subject safety.
17. Subjects who have donated plasma within seven days prior to the screening visit or where participation in this study would result in donation of blood in excess of 500 mL within a 56-day period.
18. History of sensitivity to any of the study medications, or components thereof.
