Percentage of Participants With Virologic Failure - Virologic failure was 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
Timepoint [4] 0 0
Up to Posttreatment Week 24

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.
