Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
