  Purpose
This study is to evaluate the safety, tolerability, and antiviral efficacy of ledipasvir/sofosbuvir fixed dose combination (FDC) with or without ribavirin (RBV) administered for 12 or 24 weeks in treatment-experienced subjects with chronic genotype 1 hepatitis C virus (HCV) infection.

Condition Intervention Phase
Chronic Hepatitis C Virus Drug: LDV/SOF Drug: RBV Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 3, Multicenter, Randomized, Open-Label Study to Investigate the Efficacy and Safety of Sofosbuvir/GS-5885 Fixed-Dose Combination ± Ribavirin for 12 and 24 Weeks in Treatment-Experienced Subjects With Chronic Genotype 1 HCV Infection

Primary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) 12 weeks following the last dose of study drug.

  • Incidence of Adverse Events Leading to Permanent Discontinuation From Any Study Drug [ Time Frame: Up to 24 weeks ]
    The percentage of participants who experienced an adverse event leading to permanent discontinuation from any study drug was summarized.


Secondary Outcome Measures:
  • Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24) [ Time Frame: Posttreatment Weeks 4 and 24 ]
    SVR4 and SVR24 were defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study drug, respectively.

  • Percentage of Participants With HCV RNA < LLOQ at Week 1 [ Time Frame: Week 1 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 2 [ Time Frame: Week 2 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 4 [ Time Frame: Week 4 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 8 [ Time Frame: Week 8 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 12 [ Time Frame: Week 12 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 24 [ Time Frame: Week 24 ]
  • Change From Baseline in HCV RNA at Week 1 [ Time Frame: Baseline; Week 1 ]
  • Change From Baseline in HCV RNA at Week 2 [ Time Frame: Baseline; Week 2 ]
  • Change From Baseline in HCV RNA at Week 4 [ Time Frame: Baseline; Week 4 ]
  • Change From Baseline in HCV RNA at Week 8 [ Time Frame: Baseline; Week 8 ]
  • Percentage of Participants With Virologic Failure [ Time Frame: Baseline to posttreatment Week 24 ]

    Virologic failure was defined as on-treatment virologic failure or virologic relapse.

    • On-Treatment Virologic Failure was defined as

      • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while on treatment), or
      • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
      • Non-response (HCV RNA persistently ≥ LLOQ through 8 weeks of treatment)

    Virologic relapse was defined as confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.
