Healthy male and female subjects (aged 18 to 55 years inclusive, at the time of informed consent)\n2. Body mass index (BMI) ≥ 18 kg/m2 and ≤ 32 kg/m2 at Screening\n3. Platelet count between 120 x 109/L and 300 x 109/L inclusive at Screening, Baseline Period 1, or Baseline Period 3\n4. Platelet count below the upper limit of normal at Baseline Period 2\n5. Females must not be lactating or pregnant at Screening or Baseline (as documented by a negative serum beta-human chorionic gonadotropin \\[β-hCG\\] test with a minimum sensitivity 25 IU/L or equivalent units of β-hCG). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.\n6. All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing).\n7. Females of childbearing potential must not have had unprotected sexual intercourse within 30 days before study entry and must agree to use a highly effective method of contraception (e.g., total abstinence, a nonhormonal-based intrauterine device, a double barrier method \\[such as condom plus spermicide or diaphragm plus spermicide\\], non-estrogen-based hormonal therapy, progesterone-only contraceptive implant/injection, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. The use of estrogen-based hormonal contraceptives is not allowed because of a potential increase in the risk of venous thrombosis.\n\n All females who are of reproductive potential and have been using estrogen-containing oral contraceptives must have discontinued the contraceptive product for at least 30 days before dosing, throughout the entire study period, and for 30 days after study drug discontinuation, and have been using use the aforementioned methods.\n8. Male subjects must have had a successful vasectomy (confirmed azoospermia) or they and their female partners must meet the criteria above (i.e., not of childbearing potential or practicing highly effective contraception throughout the study period and for 90 days after study drug discontinuation). No sperm donation is allowed during the study period and for at least 90 days after the last dose of study drug.\n9. Provide written informed consent\n10. Willing and able to comply with all aspects of the protocol\n\nExclusion Criteria\n\nSubjects who meet any of the following criteria will be excluded from this study:\n\n1. Evidence of clinically significant cardiovascular, hepatic, gastrointestinal, renal, respiratory, endocrine, hematologic, neurologic, or psychiatric disease or abnormalities or a known history of any gastrointestinal surgery that could impact the PK of study drug\n2. Agents associated with thrombotic events (including oral contraceptives) are required to be discontinued 30 days prior to first study drug administration\n3. Evidence of organ dysfunction or any clinically significant deviation from normal in medical history, e.g., history of splenectomy\n4. History of arterial or venous thrombosis, including partial or complete thromboses (e.g., stroke, transient ischemic attack, myocardial infarction, deep vein thrombosis, or pulmonary embolism)\n5. Known family history of hereditary thrombophilic disorders (e.g., Factor V Leiden, antithrombin III deficiency, etc.)\n6. Hemoglobin less than the lower limit of normal\n7. Clinically significant illness within 8 weeks, or a clinically significant infection within 4 weeks, of dosing\n8. Evidence of clinically significant deviation from normal in physical examination, vital signs, or clinical laboratory determinations at Screening or Baseline Periods 1 or 3\n9. A corrected QT interval using Fridericia's formula (QTcF) \\> 450 ms at Screening\n10. A known or suspected history of drug or alcohol misuse within 6 months before Screening, or a positive drug test at Screening or Baseline Periods 1 or 3\n11. Positive results for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), and hepatitis C antibody (HCVAb) tests at Screening\n12. Receipt of blood products within 4 weeks, donation of blood within 8 weeks, or donation of plasma within 1 week before dosing\n13. Known history of clinically significant drug or food allergies or experiencing significant seasonal allergy (e.g., hay fever) or hypersensitivity to avatrombopag and/or any of its excipients\n14. Use of prescription drugs within 4 weeks or within five times the drug's half-life (if that time is \\>4 weeks) before Screening\n15. Participation in another clinical trial within 60 days before dosing or concurrent enrollment in another clinical trial\n16. Unwilling or unable to abide by the requirements of the study\n17. Any condition that would make them, in the opinion of the investigator, unsuitable for the study or who, in the opinion of the investigator, are not likely to complete the study for any reason\n18. Females who are pregnant (positive β-hCG test) or breastfeeding\n19. Hypersensitivity to aspirin\n20.
