Primary Outcome Measures
NameTimeMethod
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) at 12 weeks after stopping study treatment.

Percentage of Participants Who Permanently Discontinued Study Drug Due to an Adverse EventUp to 12 weeks
Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With HCV RNA < LLOQ at 4 Weeks After Discontinuation of Therapy (SVR4)Posttreatment Week 4

SVR4 was defined as HCV RNA \< LLOQ at 4 weeks after stopping study treatment.

Percentage of Participants With HCV RNA < LLOQ at 24 Weeks After Discontinuation of Therapy (SVR24)Posttreatment Week 24

SVR24 was defined as HCV RNA \< LLOQ at 24 weeks after stopping study treatment.

Percentage of Participants With HCV RNA < LLOQ on Treatment at Week 1Week 1

Change From Baseline in HCV RNA at Week 12Baseline (Day 1); Week 12
Percentage of Participants With Virologic FailureUp to Posttreatment Week 24

Virologic failure was defined as:

* 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

* 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)
