Biochemical response and health outcomes in people with primary biliary cholangitis
Official title: Impact of Enhanced Biochemical Response on Clinical Outcomes in Patients With Primary Biliary Cholangitis: A Bidirectional Cohort Study
Run by RenJi Hospital · NCT07449793 · Data updated 2026-11-12
We will follow adults with primary biliary cholangitis who are taking ursodeoxycholic acid (UDCA) to see if their alkaline phosphatase levels after treatment predict how long they stay free of complications.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) with a confirmed PBC diagnosis per the 2018 AASLD criteria who are receiving standard-dose UDCA (13–15 mg/kg/day) and can complete study follow-up are ideal candidates.
✕Probably not a fit
Patients with other active liver diseases (such as active hepatitis B or C, autoimmune hepatitis, or primary sclerosing cholangitis), suspected hepatocellular carcinoma, recent other malignancies, pregnant or breastfeeding women, or those not on standard-dose UDCA or unable to adhere to follow-up are unlikely to benefit from the study findings.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a bidirectional cohort study using a mainland China database at RenJi Hospital that continuously collects demographics, symptoms, and biochemical data from diagnosed PBC patients. Investigators will track post-treatment alkaline phosphatase (AKP/ALP) levels in patients treated with standard-dose UDCA and record complication-free survival outcomes. The team will analyze the association between different post-treatment ALP levels and time to complications and will develop a predictive survival model. The work is observational and aims to validate prognostic markers within this Chinese patient cohort.
Why it matters
Potential benefit: If successful, the results could help clinicians identify patients at higher risk of complications and tailor monitoring or treatment decisions accordingly.
How similar studies have gone: Previous research has shown that post-treatment alkaline phosphatase levels correlate with outcomes in PBC and several prognostic models exist, though validation in a mainland China cohort is limited.
