Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse EventUp to 12 weeks
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.

Secondary Outcome Measures
NameTimeMethod
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 FailureUp 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.
