Study Details

Study Description

Brief Summary

This study is to evaluate the safety, tolerability, and antiviral efficacy of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) with or without ribavirin (RBV), administered for 8 or 12 weeks of treatment in participants with chronic genotype 1 hepatitis C virus (HCV) infection who are treatment-naive, and for 12 weeks in participants who had previously received a regimen containing a protease inhibitor for the treatment of HCV.

    Outcome Measures

    Primary Outcome Measures

    1. Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After Discontinuation of Therapy (SVR12) [Posttreatment Week 12]

      SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) 12 weeks after stopping study treatment.

    2. Incidence of Adverse Events Leading to Permanent Discontinuation of Study Drug(s) [Baseline to Week 12]

      The number of participants experiencing an adverse event leading to permanent discontinuation of study drug(s) was summarized.

    Secondary Outcome Measures

    1. Percentage of Participants With SVR at 2, 4, 8, and 24 Weeks After Discontinuation of Therapy (SVR2, SVR4, SVR8, and SVR24) [Posttreatment Weeks 2, 4, 8, and 24]

      SVR2, SVR4, SVR8, and SVR24 was defined as HCV RNA < LLOQ at 2, 4, 8, and 24 weeks following the last dose of study drug, respectively.

    2. Percentage of Participants Experiencing Viral Breakthrough or Viral Relapse [Baseline to Posttreatment Week 24]

      Viral breakthrough was defined as HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while receiving treatment, confirmed with 2 consecutive values (second confirmation value could be posttreatment), or last available on-treatment measurement with no subsequent follow-up values. Viral relapse was defined as HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement.

Viral relapse was defined as HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement.
    Time Frame Baseline to Posttreatment Week 24

    Arm/Group Description Treatment-naive participants were randomized to receive LDV 90 mg/SOF 400 mg for 8 weeks. Treatment-naive participants were randomized to receive LDV 90 mg/SOF 400 mg plus weight-based RBV (1000-1200 mg) for 8 weeks. Treatment-naive participants were randomized to receive LDV 90 mg/SOF 400 mg for 12 weeks. Treatment-experienced participants (had virologic failure following prior therapy with a PI+PEG+RBV regimen) were randomized to receive LDV 90 mg/SOF 400 mg for 12 weeks. Treatment-experienced participants (had virologic failure following prior therapy with a PI+PEG+RBV regimen) were randomized to receive LDV 90 mg/SOF 400 mg plus weight-based RBV (1000-1200 mg) for 12 weeks.
