A Pilot Study of Boceprevir for the Treatment of Genotype 6 HCV

Summary

The purpose of this study is to evaluate the antiviral efficacy of Boceprevir-based therapy for the treatment of genotype 6 chronic hepatitis C infection. Boceprevir has recently been approved for the treatment of genotype 1 chronic hepatitis C infection. Recent in vitro studies suggest similar efficacy against genotype 6 chronic hepatitis C infection. The investigators therefore hypothesise that: i) Boceprevir is a potent inhibitor of genotype 6 hepatitis C replication in vivo. ii) Boceprevir in combination with pegylated interferon-alpha and ribavirin for 24 weeks will cure a high proportion of patients chronically infected with genotype 6 chronic hepatitis C infection.
