This study is to determine the antiviral efficacy of sofosbuvir (SOF)/ledipasvir (LDV) fixed-dose combination (FDC) with and without ribavirin (RBV), and to evaluate the safety and tolerability of each regimen as assessed by review of the accumulated safety data. Approximately 150 participants with genotype 1 HCV infection, who have previously received treatment for HCV, and who have a diagnosis for cirrhosis will be enrolled. Participants will be randomized to 1 of 2 groups.
Group 1: SOF/LDV FDC tablet plus placebo to match RBV for 24 weeks
Group 2: Delayed treatment group: placebo to match SOF/LDV FDC plus placebo to match RBV for 12 weeks, followed by SOF/LDV FDC once daily plus RBV in a divided daily dose for 12 weeks
Randomization will 1:1 to the two groups and will be stratified by HCV genotype (1a, 1b; mixed or other genotype 1 results will be stratified as genotype 1a), and prior HCV therapy treatment response (never achieved HCV RNA < the lower limit of quantitation (LLOQ), or achieved HCV RNA < LLOQ).

- 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.
- 1 participant who was randomized to the LDV/SOF + RBV group who received placebo discontinued prior to receiving LDV/SOF + RBV and is excluded from the Full Analysis Set.
- 1 participant who was randomized to the LDV/SOF + RBV group received LDV/SOF + placebo, and is counted in the LDV/SOF group for the safety analysis, and in the LDV/SOF+RBV group for the efficacy analysis (ie, in the Full Analysis Set).
- 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 (ie, < 25 IU/mL) at Weeks 1, 2, 4, 8, 12, and 24 [ Time Frame: Weeks 1, 2, 4, 8, 12, and 24 ]
- Change From Baseline in HCV RNA at Weeks 1, 2, 4, 8, and 12 [ Time Frame: Baseline; Weeks 1, 2, 4, 8, and 12 ]
- Percentage of Participants With Virologic Failure [ Time Frame: Baseline to Posttreatment Week 24 ]
Virologic failure is defined as
-
On-treatment virologic failure:
- 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:
- Confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.
