Pilot Study of Budesonide for Patients With Primary Sclerosing Cholangitis

Pilot Study of Budesonide for Patients With Primary Sclerosing Cholangitis

OBJECTIVES: I. Assess the safety and effectiveness of budesonide in patients with primary sclerosing cholangitis or primary biliary cirrhosis experiencing a suboptimal response to ursodeoxycholic acid.

II. Estimate the efficacy of this therapy in these patient groups as a means of evaluating the feasibility of a long-term randomized trial.

PROTOCOL OUTLINE:

Patients receive budesonide by mouth 3 times daily for a minimum of 6 months. If liver biochemistries become normal, dosage is reduced to once daily. Treatment discontinues after 1 year.

PROTOCOL ENTRY CRITERIA:

--Disease Characteristics--

Pathologically confirmed primary sclerosing cholangitis (PSC) meeting the following criteria:

• Chronic cholestatic disease for at least 6 months
• Liver biopsy within the past 6 months compatible with the diagnosis of PSC Intra and/or extrahepatic biliary duct obstruction, beading, or narrowing

OR

Pathologically confirmed primary biliary cirrhosis (PBC) that is experiencing suboptimal response to ursodeoxycholic acid and meeting the following criteria:

• Chronic cholestatic liver disease for at least 6 months
• Positive antimitochondrial antibody
• No biliary obstruction by ultrasound, CT, or cholangiography
• Prior liver biopsy compatible with diagnosis of PBC
• Received ursodeoxycholic acid for at least 6 months

--Prior/Concurrent Therapy--

Biologic therapy:

• At least 3 months since prior D-penicillamine
• No planned transplantation for at least 1 year

Chemotherapy:
