Eligibility Criteria

18 Years - 55 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Signed, written, informed consent
  • Male or female subjects, 18 to 55 years of age.
  • Subject must have chronic infection HCV, genotype 1.
  • Serum HCV-RNA concentrations 100,000 IU/mL to 10,000,000 IU/mL
  • No prior treatment for HCV.
