Subjects with Hepatic Impairment Only

9. Documented chronic stable liver disease based on Child-Pugh score and classification (Child-Pugh Class A [mild], B [moderate], or C [severe]; at Screening and Check-in (if the classification differs when assessed at Check-in compared to Screening, enrollment of the subject into a hepatic category will be based on the score at Screening):

• 'Documented' is defined by at least 1 of the following: medical history, physical examination, hepatic ultrasound, computed axial tomography scan, magnetic resonance imaging, and/or liver biopsy.

• 'Chronic' is defined as >6 months.

• 'Stable' is defined as no clinically significant change in disease status within the last 1 month (30 days), as documented by the subject's recent medical history (eg, no worsening of clinical signs of hepatic impairment, or no worsening of total bilirubin or prothrombin time, at the discretion of the Investigator [or designee] or Medical Monitor).

10. Subjects with mild, moderate, or severe hepatic impairment may have medical findings consistent with their hepatic dysfunction as determined by medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations at Screening and Check-in (Day -1), as assessed by the Investigator (or designee).
