  Purpose

This study is a 24-week multicenter, randomized, double-blind control trial with ursodeoxycholic acid (UDCA) in patients with chronic hepatitis C in Japan. The primary objectives of this study are to verify the superiority of efficacy of UDCA 600 or 900mg/day to that of 150mg/day and the safety of UDCA treatment.

Primary Outcome Measures:
  • Alanine Aminotransferase at Baseline [ Time Frame: 0 week ] [ Designated as safety issue: No ]
  • Percentage Change of Alanine Aminotransferase From Baseline at Week 24 [ Time Frame: 24 weeks (from baseline to Week 24) ] [ Designated as safety issue: No ]
    Percentage change=[(measured value at Week 24 - measured value at baseline)/measured value at baseline]*100


Secondary Outcome Measures:

  • Percentage Change of Aspartate Aminotransferase From Baseline at Week 24 [ Time Frame: 24 weeks (from baseline to Week 24) ] [ Designated as safety issue: No ]
    Percentage change=[(measured value at Week 24 - measured value at baseline)/measured value at baseline]*100

  • Gamma-glutamyl Transpeptidase at Baseline [ Time Frame: 0 week ] [ Designated as safety issue: No ]
  • Percentage Change of Gamma-glutamyl Transpeptidase From Baseline at Week 24 [ Time Frame: 24 weeks (from baseline to Week 24) ] [ Designated as safety issue: No ]
    Percentage change=[(measured value at Week 24 - measured value at baseline)/measured value at baseline]*100

Detailed Description:

This study is a 24-week multicenter, randomized, double-blind control trial with ursodeoxycholic acid (UDCA) in patients with chronic hepatitis C in Japan. The primary objectives of this study are to verify the superiority of efficacy of UDCA 600 or 900mg/day to that of 150mg/day and the safety of UDCA treatment. The primary endpoint was percent changes of serum alanine aminotransferase(ALT) levels at 24-week of administration compared to pre-administration levels and secondary endpoints, serum aspartate aminotransferase(AST) and gamma-glutamyltranspeptidase(gamma-GTP) levels. Further, changes of bile acid composition and HCV-RNA levels at 24-week of administration were examined.
