Brief summary
The primary purpose of this study is to evaluate the pharmacodynamic (i.e. hepatitis C virus (HCV) viral load), pharmacokinetic and safety profiles between two treatment groups receiving different doses of DEB025 in combination with ribavirin (RBV) during the first 12 weeks treatment in chronic hepatitis C genotype (GT)-2 and GT-3 patients who had previously failed interferon therapy or were intolerant or unable to take interferon.
Interventions
ALV 100 and 200 mg soft gel capsules administered orally
RBV 200 mg tablets (weight-based dose: \< 75 mg = 1000 mg/day; ≥ 75 kg = 1200 mg/day) administered orally in a divided daily dose
