  Purpose

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.

Primary Outcome Measures:
  • To assess the antiviral activity of VCH-222, in subjects with genotype 1 hepatitis C virus (HCV) infection after once (QD) or twice (b.i.d.) daily dosing for 3 days (Part A) [ Time Frame: Daily for the first 3 days and at each study visit ] [ Designated as safety issue: Yes ]
  • To assess the antiviral activity of VCH-222, in subjects with genotype 1 HCV infection after b.i.d. daily dosing for 12 weeks in combination with Peg-interferon-alfa-2a and ribavirin (Part B) [ Time Frame: Week 4 and Week 12 ] [ Designated as safety issue: Yes ]
  • Assess the safety and tolerability of VCH-222 when administered in combination with Peg-IFN-alfa-2a/RBV for 12 weeks (Part B) [ Time Frame: Study visits throughout part B ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To assess the safety and tolerability of VCH-222 when administered for 3 days in monotherapy (Part A) [ Time Frame: Study visits throughout Part A ] [ Designated as safety issue: Yes ]
  • To evaluate the pharmacokinetic (PK) profile of VCH-222 in HCV infected subjects (Part B) [ Time Frame: Time points through Part B ] [ Designated as safety issue: No ]
