Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving Sustained Virologic Response (SVR)12Posttreatment Week 12

SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ; ie, 25 IU/mL) 12 weeks after cessation of therapy.

Number of Participants Experiencing Adverse Events Leading to Permanent Discontinuation of Study DrugBaseline to Week 12

The number of participants experiencing adverse events leading to permanent discontinuation of study drug was summarized. Adverse events may or may not have been related to study treatment. Participants discontinuing study drug were permitted to remain on the study for further assessments.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Viral BreakthroughBaseline to Week 12

Viral breakthrough was defined as HCV RNA ≥ LLOQ after having previously had HCV RNA \< LLOQ while receiving treatment, confirmed with 2 consecutive values (second confirmation value could be posttreatment), or last available on-treatment measurement with no subsequent follow-up values.

Percentage of Participants With Viral RelapseEnd of treatment to post-treatment Week 24

Viral relapse was defined as HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA \< LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement.

Percentage of Participants Achieving SVR4Posttreatment Week 4

SVR4 was defined as HCV RNA \< LLOQ 4 weeks after cessation of therapy

Percentage of Participants Achieving SVR24Posttreatment Week 24

SVR24 was defined as HCV RNA \< LLOQ 24 weeks after cessation of therapy
