|
Percentage of Participants Achieving SVR12
Prazo: Posttreatment Week 12
|
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ, ie, < 25 IU/mL) 12 weeks after cessation of therapy. For the purposes of this efficacy analysis, the posttreatment period began after the end of active treatment (following Week 12 for the SOF+RBV+placebo arm, and Week 16 for the SOF+RBV arm). |
Posttreatment Week 12

Adverse Events Leading to Permanent Discontinuation of Study Drug
Prazo: Baseline to Week 16
|
Adverse events which led to permanent discontinuation of study drug may or may not have been related to study treatment.

Percentage of Participants Achieving SVR4
Prazo: Posttreatment Week 4
|
SVR4 was defined as HCV RNA < LLOQ 4 weeks after cessation of therapy. For the purposes of this efficacy analysis, the posttreatment period began after the end of active treatment (following Week 12 for the SOF+RBV+placebo arm, and Week 16 for the SOF+RBV arm). |
Posttreatment Week 4
|
|
Percentage of Participants Achieving SVR24
Prazo: Posttreatment Week 24
|
SVR24 was defined as HCV RNA < LLOQ 24 weeks after cessation of therapy. For the purposes of this efficacy analysis, the posttreatment period began after the end of active treatment (following Week 12 for the SOF+RBV+placebo arm, and Week 16 for the SOF+RBV arm). |
Posttreatment Week 24
|
|
Percentage of Participants With Viral Breakthrough
Prazo: Up to 16 weeks
|
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. For the purposes of this efficacy analysis, assessments were made during active treatment (up to Week 12 for the SOF+RBV+placebo arm, and Week 16 for the SOF+RBV arm). |
Up to 16 weeks
|
|
Percentage of Participants With Viral Relapse
Prazo: End of treatment to posttreatment 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. For the purposes of this efficacy analysis, the posttreatment period began after the end of active treatment (following Week 12 for the SOF+RBV+placebo arm, and Week 16 for the SOF+RBV arm). |
