Timeframe: Up to 24 weeks

Population: Full Analysis Set

On-treatment virologic failure was defined as: 1. Viral breakthrough: HCV RNA ≥ LLOQ after having previously had HCV RNA \< LLOQ while on treatment, confirmed with 2 consecutive values (second confirmation value may have been posttreatment) or with a last available on-treatment measurement and no subsequent follow-up values, or 2. Viral rebound: \> 1 log10 IU/mL increase in HCV RNA from nadir while on treatment, confirmed with 2 consecutive values (second confirmation value may have been posttreatment) or with a last available on-treatment measurement and no subsequent follow-up values, or 3. Nonresponse: HCV RNA persistently ≥ LLOQ through 8 weeks of treatment
