Overview
Brief Summary
The primary objective of this study is to evaluate the efficacy, safety and tolerability of treatment with sofosbuvir/velpatasvir (Epclusa®; SOF/VEL) with ribavirin (RBV) for 24 weeks in adults with chronic hepatitis C virus (HCV) infection who participated in a prior Gilead sponsored study and did not achieve sustained virologic response (SVR).

Outcomes
Primary Outcomes
Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)
Time Frame: Posttreatment Week 12
SVR12 is defined as HCV RNA \< the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study drug.
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event
Time Frame: Up to 24 weeks
Secondary Outcomes
- Percentage of Participants With Sustained Virologic Response 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)(Posttreatment Weeks 4 and 24)
- Percentage of Participants With HCV RNA < LLOQ On-treatment(Baseline to Week 24)
- HCV RNA Change From Baseline(Baseline to Week 24)
- Percentage of Participants With Virologic Failure(Up to Posttreatment Week 24)
