Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess antiviral activity when administered alone for 3 days or in combination with peginterferon and ribavirin for 12 weeks. This study will also evaluate the safety and tolerability of treatment with VCH-222 when given alone or in combination with peginterferon and ribavirin.

The study will also evaluate the pharmacokinetic profile of VCH-222 in HCV infected subjects.
