About this study
OBJECTIVES: I. Compare the effects of ursodiol (ursodeoxycholic acid), with and without methotrexate, on pruritus, incapacitation index, and serum markers of activity and severity in patients with primary biliary cirrhosis.
II. Compare the effects of these regimens on the development of ascites, encephalopathy, varices (or bleeding from pre-existing varices), histologic liver changes, transplantation, and survival.
III. Compare the toxicity and safety of each regimen.

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution and Ludwig histologic stage.
All patients are treated with ursodiol (ursodeoxycholic acid, UDCA) for 6 months. If entry criteria continue to be met, patients are randomly assigned to UDCA/methotrexate or UDCA/placebo.
Combination therapy continues for at least 5 years.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing methotrexate and ursodiol in people with Liver Cirrhosis, Biliary, run by National Center for Research Resources (NCRR).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
