Low-Dose Oral Methotrexate Versus Colchicine for Primary Biliary Cirrhosis
I. Compare the efficacy of low-dose oral pulse methotrexate (MTX) and ursodiol versus colchicine and ursodiol in patients with primary biliary cirrhosis (PBC).
II. Determine the optimum dose and duration of MTX treatment.
III. Investigate the role of fibrogenic cytokines (FC) in PBC pathogenesis and the effect of treatment on FC production.

|Official Title:||Phase III Randomized, Double-Blind, Placebo-Controlled Study of Low-Dose Oral Methotrexate Versus Colchicine for Primary Biliary Cirrhosis|
|Study Start Date:||November 1989|
This is a randomized, double-blind study. Patients are stratified by prior/concurrent medical management.
Patients in the first group are treated with oral methotrexate 3 times a week and a daily oral placebo.
Patients in the second group are treated with daily oral colchicine and an oral placebo 3 times a week.
Therapy continues for 10 years. Beginning year 2, daily oral ursodiol is administered to all patients. Patients with disease progression are crossed to the alternate group or undergo liver transplantation if clinically indicated.
