Outcomes

Primary Outcome Measures

Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Cessation 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 Prematurely Discontinued Study Drug Due to Any Adverse Event

Secondary Outcome Measures

Percentage of Participants With Sustained Virologic Response 4 Weeks After Cessation of Therapy (SVR4)
SVR4 was defined as HCV RNA < LLOQ at 4 weeks after stopping study treatment.
Percentage of Participants With HCV RNA < LLOQ at Week 2
Percentage of Participants With HCV RNA < LLOQ at Week 4
Percentage of Participants With HCV RNA < LLOQ at Week 8

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 on 2 consecutive measurements 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 12 weeks of treatment) Virologic 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
