NCT00200343

Brief Summary

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.
