Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)Posttreatment Week 12

SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ, ie, \< 25 IU/mL) 12 weeks following the last dose of study drug. Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.

Adverse Events Leading to Permanent Discontinuation of Study Drug(s)Up to 24 weeks

The percentage of participants experiencing an adverse event leading to permanent discontinuation of study drug(s) was analyzed.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)Posttreatment Weeks 4 and 24

SVR4 and SVR24 was defined as HCV RNA \< LLOQ at 4 and 24 weeks following the last dose of study drug, respectively. Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.

Percentage of Participants Experiencing Viral Breakthrough or Viral RelapseUp to Posttreatment Week 24

Viral breakthrough was defined as having confirmed detectable HCV RNA levels (HCV RNA \> LLOQ) after having previously had undetectable HCV RNA levels (HCV RNA \< LLOQ) while on treatment.

Viral relapse was defined as having achieved undetectable HCV RNA levels (HCV RNA \< LLOQ) at end of treatment, but did not achieve an SVR.

Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.
