Primary Outcome Measures:
  • Percentage of subjects in each treatment group with sustained virologic response 12 weeks post-treatment [ Time Frame: 12 weeks after last actual dose of study drug ] [ Designated as safety issue: No ]
    Hepatitis C virus ribonucleic acid less than the lower limit of quantification

Secondary Outcome Measures:
  • Changes in hemoglobin laboratory values during treatment [ Time Frame: During treatment (from baseline through Week 12) ] [ Designated as safety issue: Yes ]
    Hemoglobin laboratory values below the the lower limit of normal.

  • Percentage of subjects with virologic failure during treatment [ Time Frame: During treatment (up to 12 weeks) ] [ Designated as safety issue: No ]
    Hepatitis C virus ribonucleic acid greater than the lower limit of quantification

  • Percentage of subjects with virologic relapse after treatment [ Time Frame: After last dose until 12 weeks post-treatment ] [ Designated as safety issue: No ]
    Hepatitis C virus ribonucleic acid greater than the lower limit of quantification
