- Primary Outcome Measures
Name Time Method Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) Posttreatment Week 12 SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ; ie, 15 IU/mL) at 12 weeks after stopping study treatment.
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event Up to 12 weeks
- Secondary Outcome Measures
Name Time Method Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24) Posttreatment Weeks 4 and 24 SVR4 and SVR 24 were defined as HCV RNA \< LLOQ at 4 and 24 weeks after stopping study treatment, respectively.
Percentage of Participants With Virologic Failure Up to Posttreatment Week 24 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.
