• Subjects must test negative for HIV

• Subjects must test negative for drugs of abuse at screening

Exclusion Criteria:

All Subjects :

• Concomitant Medication: Treatment with CYP3A4 inducers, such as rifampin and St. John's Wort within 14 days of Day 1 until they leave the clinic on Day 7

• Donation of blood within 30 days of Day 1

• Recent participation in an investigational drug study during which active medication was given within 30 days of Day 1

Healthy Volunteer:

• Existing failure of a major organ system, or a medical disorder that would impair the subject's ability to complete the study (in the opinion of the investigator or the sponsor), eg history of blood coagulation disorders

• Hematocrit value < 34% in the control group at screening

Renal Impairment Groups:

• Existing failure of a major organ system or a medical disorder (other than the target disease) which would impair the subject's ability to complete the study (in the opinion of the investigator or the sponsor)

• Concomitant Medication: Renal impairment subjects taking phosphate binders, ion exchange resins and/or iron supplements may take them with their meals, but must withhold them on the morning of Day 1 (dosing day) until after their 4 hour post-dose tests and procedures are performed.

• Myocardial infarction, coronary artery bypass graft or percutaneous transluminal coronary angiography within 6 months of Day 1; unstable angina; uncontrolled significant hypertension within 3 months of Day 1; cerebral vascular accident or transient ischemic attack within 12 months of Day 1

• Subjects with hypertension who have had a medication or dose change within one week of Day 1

• Subjects requiring dialysis

• Subjects with kidney transplants

• Liver transaminase (AST, ALT) greater than 5 times the ULN at screening; any active liver disease or unexplained or persistent elevations in liver function tests

• Hematocrit value < 24% in the renal impaired groups
