Eksperimentel: SOF+RBV+placebo
Participants were randomized to receive SOF+RBV for 12 weeks followed by placebo to match SOF plus placebo to match RBV for 4 weeks.
|
Sofosbuvir (SOF) 400 mg tablet was administered orally once daily.
Andre navne:
Ribavirin (RBV) tablets was administered orally in a divided daily dose according to package insert weight-based dosing recommendations (< 75kg = 1000 mg and ≥ 75 kg = 1200 mg).
Placebo to match SOF was administered orally once daily.
Placebo to match RBV was administered orally twice daily.

Percentage of Participants Achieving SVR12
Tidsramme: 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). |

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
Tidsramme: 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
Tidsramme: 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). |
