  Purpose

This is a multicenter, randomized, controlled trial of high dose ursodiol versus placebo for patients with primary sclerosing cholangitis (PSC). The average duration of follow-up will be approximately five years with important clinical endpoints such as death, eligibility for liver transplantation, changes in histology and cholangiogram as well as liver biochemistries and quality of life data collected.

Primary Outcome Measures:
  • To complete the evaluation of the effects of urso at a dose of 28-30 mg/kg/day on time to the development of cirrhosis, varices, cholangiocarcinoma, meeting minimal listing criteria for liver transplantation, or death in patients with PSC. [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Compare high dose urso vs placebo on liver biochemistries, histology stage, cholangiography, Mayo Risk Score, quality of life, toxicity, tolerability, development of cholangitis. Establish a serum, tissue & data bank for future studies. [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 150
  Eligibility

Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria
  • Chronic cholestatic disease of at least six months' duration.
  • Serum alkaline phosphatase at least 1 ½ times the upper limits of normal.
  • Retrograde, operative, percutaneous, or magnetic resonance cholangiography demonstrating intrahepatic and/or extrahepatic biliary duct obstruction, beading, or narrowing consistent with PSC within one year of the study entry.
  • Liver biopsy in the previous one year which is available for review and compatible with the diagnosis of PSC. Compatible biopsy features include fibrous cholangitis, ductopenia with periportal inflammation and biliary fibrosis.
