Pharmacokinetics and Safety of ABT-493 and ABT-530 in Subjects With Normal and Impaired Renal Function

Up to 48 subjects will be selected and enrolled according to the subject selection criteria:
8 subjects with mild renal impairment (Group 1), 8 subjects with moderate renal impairment
(Group 2), 8 subjects with severe renal impairment (Group 3), 8 subjects with end stage
renal disease that are not yet on dialysis (Group 4), 8 healthy subjects with normal renal
function (Group 5), and 8 subjects with end stage renal disease on hemodialysis (Group 6).

Inclusion Criteria: All Subjects

- Females must have negative results for pregnancy tests performed:

- At Screening on a urine specimen, and

- On a serum sample obtained on Study Day -2 (prior to dosing).

- Body Mass Index (BMI) is ≥ 18 to ≤ 38 kg/m2, inclusive.

- Body Weight > 50 kg.

Subjects with Normal Renal Function

In addition to the main inclusion criteria above for all subjects, the following criteria
must be met for subjects with normal renal function enrolled in Group 5:

- Judged to be in general good health based upon the results of a medical history,
physical examination, and 12-lead electrocardiogram (ECG).

- At screening, estimated GFR (by MDRD equation) should be ≥ 90 mL/min/1.73 m2.

Subject with Renal Impairment

In addition to the main inclusion criteria for all subjects, the following criteria must
be met for all subjects with renal impairment enrolled in Groups 1, 2, 3, 4 and 6:

- Judged to be in stable condition and acceptable for study participation based upon
the results of a medical history, physical examination, laboratory profile and ECG.

- Presence of chronic renal impairment as indicated by medical history and a screening
estimated GFR (by MDRD equation) < 90 mL/min/1.73 m2.

- Subjects with ESRD undergoing hemodialysis should have been receiving dialysis for at
least 1 month.

Exclusion Criteria: - History of significant sensitivity to any drug.

- Pregnant or breastfeeding female.

- Recent (6-month) history of drug or alcohol abuse.

- Positive test result for hepatitis A virus immunoglobulin M (HAV-IgM), hepatitis B

Ab). Negative HIV status will be confirmed at Screening and the results will be
maintained confidentially by the study site.

- Subjects on strict vegetarian diet.
