Chronic Hepatitis C Infection
Conditions
Brief summary
The purpose of this study is to assess the safety, tolerability, and efficacy of Sofosbuvir containing regimens in treatment-naive or treatment-experienced patients with HCV genotypes 2 infection.
Interventions
Sofosbuvir (SOF) 400 mg tablet administered orally once daily. Ribavirin (RBV) tablets administered orally in a divided daily dose according to package insert weight-based dosing recommendations (\< 75kg = 1000 mg and ≥ 75 kg = 1200 mg).
Sofosbuvir (SOF) 400 mg tablet administered orally once daily. Daclatasvir (DCV) 60mg tablet administered once daily.
Ledipasvir 90 mg /Sofosbuvir 400 mg (LDV/SOF) FDC tablet administered orally once daily

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with sustained virologic response 12 weeks after discontinuation of therapy | Post treatment Week 12 | SVR12 is defined as HCV RNA \< lower limit of quantification (LLOQ) 12 weeks after last dose of study drug. |
| Proportion of participants with adverse events leading to permanent discontinuation of study drug(s) | Baseline up to Week 24 | — |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with unquantifiable HCV viral load at specified time points during and after treatment | Baseline up to Week 24 | — |
| HCV RNA levels and change during and after treatment. | Baseline up to Week 24 | — |
| Proportion of participants with on-treatment virologic breakthrough and relapse | Baseline up to Week 24 | Viral breakthrough is defined as having achieved undetectable HCV RNA levels (HCV RNA \< LLOQ) during treatment, but did not achieve a sustained virologic response (SVR). Viral relapse is defined as having achieved undetectable HCV RNA levels (HCV RNA \< LLOQ) within 4 weeks of end of treatment, but did not achieve an SVR. |
