Outcome Measures

Primary Outcome Measures

1. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) [12 weeks after the last actual dose of study drug]

   SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug.

Secondary Outcome Measures

1. Percentage of Participants With On-treatment Virologic Failure [Treatment Weeks 1, 2, 4, 8, and 12 (end of treatment) or premature discontinuation from treatment]

   On-treatment virologic failure was defined as confirmed increase of > 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline HCV RNA during treatment; confirmed HCV RNA ≥ 100 IU/mL after HCV RNA < LLOQ during treatment, or HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment.

2. Percentage of Participants With Post-treatment Relapse [From the end of treatment through 12 weeks after the last dose of study drug]

   Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA levels < LLOQ at the end of treatment, excluding reinfection.
