Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with a confirmed diagnosis of Primary Biliary Cholangitis and evidence of compensated cirrhosis.

Probably not a fit

Patients who have previously been treated with Seladelpar or have other significant medical conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of Seladelpar in improving clinical outcomes for patients diagnosed with Primary Biliary Cholangitis (PBC) who also have compensated cirrhosis. Participants will receive either Seladelpar or a placebo, and their health will be monitored throughout the study. The trial aims to determine if Seladelpar can provide significant benefits in managing this chronic liver disease. Eligible participants must be at least 18 years old and have a confirmed diagnosis of PBC with evidence of cirrhosis.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of Primary Biliary Cholangitis and enhance the quality of life for affected patients.

How similar studies have gone: Other studies have shown promise in treating Primary Biliary Cholangitis, but the specific use of Seladelpar in this context is being evaluated for the first time.
