Summary
Brief summary
The primary objectives of this study are to evaluate the safety and efficacy of treatment
with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in adults with chronic hepatitis C
virus (HCV) infection who have previously received treatment with direct-acting antiviral
therapy.

Participants randomized to placebo may be eligible for deferred treatment with active
SOF/VEL/VOX.
