Outcome Measures

Primary Outcomes (1)

  • Mean Change in HCV-RNA (Hepatitis C Virus Ribonucleic Acid) Levels From Baseline Through 24 Weeks of Treatment

    Measure the mean absolute changes in HCV-RNA (Hepatitis C virus ribonucleic acid, also known as "viral load") levels in the blood from before treatment (baseline) through 24 weeks of treatment. Mean Absolute Change in HCV-RNA (log) = log10(HCV-RNA Week 24) - log10(HCV-RNA Baseline)

    Baseline and 24 weeks

Secondary Outcomes (1)

  • Mean Change in Aminotransferases From Baseline to 24 Weeks of Treatment

    Baseline and 24 weeks
