NCT02470858

Brief Summary

The study is designed to test the hypothesis that the addition of a protease inhibitor to dual NS5a-NS5B nucleoside prodrug analog will enhance antiviral efficacy and hence shorten the treatment duration to 3 weeks.

Outcome Measures

Primary Outcomes (2)

  • Proportion of participants with sustained virologic response 12 weeks after discontinuation of therapy (SVR12)

    SVR12 is defined as HCV RNA \< lower limit of quantification (LLOQ) 12 weeks after last dose of study drug.

    Post treatment Week 12

  • Proportion of participants with adverse events leading to permanent discontinuation of study drug(s)

    Baseline up to Week 24

Secondary Outcomes (3)

  • Proportion of participants with unquantifiable HCV viral load at specified time points during and after treatment.

    Baseline up to Week 24

  • HCV RNA levels and change during and after treatment.

    Baseline up to Week 24

  • Proportion of participants with on-treatment virologic breakthrough and relapse

    Baseline up to Week 24
