- Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, < 25 IU/mL in Korea and Taiwan and < 15 IU/mL in China) 12 weeks following the last dose of study drug.
- Percentage of Participants Who Permanently Discontinued Study Drug Due to an Adverse Event [ Time Frame: Up to 12 weeks ]
- Percentage of Participants With Sustained Virologic Response at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24) [ Time Frame: Posttreatment Weeks 4 and 24 ]SVR4 and SVR24 were defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study drug, respectively.
- Percentage of Participants Experiencing Viral Breakthrough [ Time Frame: Up to 12 weeks ]Viral breakthrough were defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) during treatment, but did not achieve a sustained virologic response (SVR).
- Percentage of Participants Experiencing Viral Relapse [ Time Frame: Week 12 to Posttreatment Week 24 ]Viral relapse is defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) within 4 weeks of end of treatment, but did not achieve an SVR.
- HCV RNA and Change From Baseline in HCV RNA Through Week 12 for China Only [ Time Frame: Baseline; Week 12 ]
