Virologic failure was defined as: * 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), or * Relapse (HCV RNA ≥ LLOQ during the post-treatment period having achieved HCV RNA \< LLOQ at end of treatment, confirmed with 2 consecutive values or last available post-treatment measurement)
