The aim of this study is to investigate the efficacy and safety of an insulin-sensitizer (Actos) added to a standard Pegasys/Copegus combination therapy of chronic hepatitis C in patients who have previously failed a pegylated-interferon-alpha / ribavirin combination without the insulin sensitizer. The primary endpoint is the initial virological response (level of HCV RNA in serum) as evaluated after 12 weeks of triple therapy.

  • Changes (vs. baseline) of body weight, HOMA score, after 4, 12 and 48 weeks of therapy and after 24 weeks of follow-up [ Time Frame: Weeks 4, 12 and 48 of therapy ] [ Designated as safety issue: Yes ]
  • Improvement (vs. baseline) of glucose tolerance parameters after 12 and 48 weeks of therapy and after 24 weeks of follow-up [ Time Frame: Weeks 12 and 48 of therapy; week 24 of FU ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 35
Study Start Date: January 2007
Estimated Study Completion Date: July 2007
Primary Completion Date: July 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Pioglitazone
    Increase response to interferon alpha plus ribavirin by increasing insulin sensitivity
    Drug: Increase response to interferon alpha plus ribavirin by increasing insulin sensitivity
    Pioglitazone 15 mg PD will be given to chronic hepatitis C patients in addition to peginterferon-alpha2a and ribavirin (Standard of Care, SOC) for 12 weeks to improve virological response. All recruited patients will be previous non-responders to SOC.
