Outcomes

Primary Outcome Measures

Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12)
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) at 12 weeks after stopping study treatment.
Percentage of Participants Who Permanently Discontinue Study Drug Due to an Adverse Event

Secondary Outcome Measures

Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)
SVR4 and SVR24 were defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.
Percentage of Participants With HCV RNA < LLOQ On Treatment
Change From Baseline in HCV RNA
Percentage of Participants With Virologic Failure
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), or Virologic relapse: Confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit
