• Moderate renal impairment: Have eGFR determined by CKD-EPI of greater than or equal to 30 mL/min and less than 60 mL/min.
• Are not currently or have not previously been on hemodialysis, including peritoneal dialysis.
• Have acceptable blood pressure as defined by systolic blood pressure less than 160 mmHg and diastolic blood pressure less than 95 mmHg, as well as acceptable pulse rate as defined by no less than 50 bpm and no greater than 100 bpm

Exclusion Criteria:

• Have history of chronic liver disease, or any evidence for hepatic impairments, or

  * ALT or AST greater than 2.5 × ULN without any increase in TBL or * TBL greater than 1.5 × ULN without any increase in aminotransferase.
