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 transplanation, changes in histology and cholangiogram as well as liver biochemistries
and quality of life data collected.
Official title: Multicentered Randomized Trial of High-Dose Urso in Primary Sclerosing Cholangitis
Study design: Treatment, Randomized, Double-Blind, Placebo Control, Single Group Assignment, Safety/Efficacy Study
Minimum age: 18 Years.
Maximum age: 75 Years.
- 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.
