Inclusion Criteria:

• 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.

• 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
