Primary Outcome Measures:
  • - Efficacy: Undetectable plasma HCV RNA (less than 100 copies/mL) at the end of the 24-week post-treatment follow-up period.
  • - Safety: The proportion of patients with hemoglobin less than 10 g/dL at any time during treatment or at least 2.5 g/dL drop from baseline.

Secondary Outcome Measures:
  • - Efficacy: Undetectable plasma HCV RNA at treatment week 24
  • - Efficacy: Undetectable or at least a 2-log drop from baseline at treatment weeks 12 and 24
  • - Safety: Monitoring of adverse events
  • - Safety: Monitoring of abnormal changes in laboratory parameters that are not disease-related

Estimated Enrollment: 900
Study Start Date: June 2004
Study Completion Date: May 2006
Primary Completion Date: May 2006 (Final data collection date for primary outcome measure)
Detailed Description:

Compare the efficacy and safety of viramidine 600 mg twice a day (BID) versus ribavirin 1000/1200 mg/day, both drugs administered in combination with pegylated interferon alfa-2a to treatment-naive patients with chronic hepatitis C (CHC)
