11. Severe or moderate renal dysfunction or a history of kidney, other organ, bone marrow, or stem cell transplant
12. If male, unwilling to refrain from donating sperm or to use appropriate birth control when engaging in sexual intercourse for the duration of the study and a period of 14 days after discharge from the clinic. Surgically sterile male subjects were eligible

Surgically sterile (as a result of hysterectomy or bilateral oophorectomy), or postmenopausal (absence of menses greater than 12 months and age > 45 years) female subjects were eligible. All females were to have had a negative pregnancy test at Screening and at clinic admission

15. Pre existing thrombocytopenia (platelet blood count < 30,000 platelets) at Screening or other clinically significant findings in complete blood count (CBC) test.
16. A history of current febrile illness, hepatocellular carcinoma, acute liver disease, severe hepatic encephalopathy, or biliary liver cirrhosis.
17. A history of significant acute medical illness (new conditions and/or exacerbation of pre existing conditions or major surgery within 4 weeks of study drug administration), active alcoholic hepatitis, current or recent (within 2 months before Day 0) history of significant gastrointestinal disease
18. Clinical evidence of severe ascites, as judged by the Investigator
19. A history of surgical portosystemic shunt

20. For subjects in the healthy control group only:

    • A seated systolic blood pressure (SBP) of < 90 or > 140 mmHg, confirmed by repeat measurement
    • A seated diastolic blood pressure (DBP) of < 40 or > 90 mmHg
    • A history of vitamin preparation or supplement use (including St. John's Wort and ginseng) within 7 days prior to Day 0, or caffeine and methylxanthine (e.g., tea, chocolate) containing foods/beverages within 48 h prior to Day 0
    • A history of prescription or over-the-counter (OTC) drug use within 7 days or 5 half lives of the drug, whichever was longer, prior to Day 0
    • A history of liver disease or liver injury as indicated by an alanine aminotransferase (ALT), aspartate aminotransferase (AST), > 2.5 × the upper limit of normal (ULN) at Screening, or serum bilirubin > 1.5 × ULN
    • Evidence of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection

21. For subjects in the hepatic impairment group only:

    • A seated SBP of < 80 or > 160 mmHg, confirmed by repeat measurement
    • A seated DBP of < 40 or > 100 mmHg
