Primary Outcome Measures:
  • Percentage of subjects in each treatment group with sustained virologic response 12 weeks post-treatment [ Time Frame: 12 weeks after the actual dose of active 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: Day 1 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: Up to Week 12 ] [ 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: Up to post-treatment Week 48 ] [ Designated as safety issue: No ]
    Hepatitis C virus ribonucleic acid greater than the lower limit of quantification

Enrollment: 305
Study Start Date: March 2013
Study Completion Date: September 2014
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
