Summary
Brief summary
The primary objectives of this study are to compare the efficacy, safety, and tolerability of
treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed dose combination (FDC)
for 8 weeks with that of SOF/VEL FDC for 12 weeks in direct-acting antiviral-naive
participants with chronic hepatitis C virus (HCV) infection.
