Subject has provided written consent.
In the investigator's opinion, the subject is able to understand and comply with protocol requirements, instructions, and protocol stated restrictions and is likely to complete the study as planned.
Subject is in good health as deemed by the investigator.
Creatinine clearance of greater than 50 mL/min (Cockcroft-Gault)
Male or female, 18-55 years of age for HV and 18-65 years of age for subjects with CHC.
Body mass index (BMI) 18-32 kg/m2 inclusive for HV and 18-36 kg/m2 for subjects with CHC, minimum weight 50 kg in both populations.
A female is eligible to participate in this study if she is of non childbearing potential.
If male, subject is surgically sterile or practicing specific forms of birth control.

Additional inclusion criteria for subjects with CHC genotype 1 infection:

Positive HCV antibody and a positive HCV RNA at screening.
Documentation of CHC infection for greater than 6 months at screening
CHC genotype 1 infection at screening
HCV RNA viral load ≥ 105 and ≤108 IU/mL using a sensitive quantitative assay.
Liver biopsy within two years or Fibroscan evaluation within 6 months prior to screening that clearly excludes cirrhosis. Fibroscan liver stiffness score must be < 12 kPa.
Absence of hepatocellular carcinoma as indicated by an ultrasound scan conducted during screening
No prior treatment for CHC
Absence of history of clinical hepatic decompensation.

Laboratory values include:

Prothrombin time < 1.5x ULN
Platelets > 120,000/mm3
Albumin > 3.5 g/dL, bilirubin < 1.5 mg/dL at screening (subjects with documented Gilbert's disease allowed).
Serum alanine aminotransferase (ALT) concentration < 5 x ULN
Alpha Fetoprotein (AFP) concentrations ≤ ULN. If AFP is ≥ ULN, absence of a hepatic mass must be demonstrated by ultrasound within the screening period.

Exclusion Criteria:

Participation in an investigational drug trial or having received an investigational vaccine within 30 days or 5 half lives (whichever is longer) prior to study medication.
Clinically significant blood loss or elective blood donation of significant volume.
For healthy subjects, history of regular use of tobacco.
The subject has a positive pre-study drug screen.

Laboratory abnormalities including:

Thyroid Stimulating Hormone (TSH) > ULN
Hematocrit < 34 %
White blood cell counts < 3,500/mm3
