6. Participants who have chronic (≥ 6 months) moderate or severe hepatic insufficiency (of any etiology) that has been clinically stable (no acute episodes of illness due to deterioration in hepatic function) for at least 1 month prior to Screening and must also remain stable throughout the Screening period.

Exclusion Criteria

6. History of a major surgical procedure within 30 days prior to Screening;

7. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs except that appendectomy and hernia repair will be allowed. Bariatric surgery will not be allowed;

9. Poor peripheral venous access;

10. Receipt of blood products within 2 months prior to Check-In Visit;

11. Significant history or clinical manifestation of any metabolic (including thyroid), allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular (including any prior history of cardiomyopathy or cardiac failure), gastrointestinal (GI), neurological, or psychiatric disorder;

12. Positive serologic test for hepatitis B surface antigen or for hepatitis C virus antibody at Screening;

13. Frequent headaches (> twice a month) and/or migraines, recurrent nausea and/or vomiting, diarrhea;

14. Participants with symptomatic hypotension at Screening, whatever the decrease of blood pressure, or asymptomatic postural hypotension;

15. History of unstable diabetes mellitus;

16. Participants who have a transjugular intrahepatic portosystemic shunt and/or have undergone portacaval shunting;

17. Participant has shown evidence of hepatorenal syndrome or has creatinine clearance ≤ 60 mL/min;

18. Participants has required treatment for GI bleeding within the 6 months prior to Check-In Visit;
