Maralixibat (Livmarli) use in Alagille syndrome and PFIC — Japanese database analysis
Official title: A Cohort Study to Investigate the Risk of Liver Disorder of Livmarli Oral Solution in Patients With Japan Alagille Syndrome (ALGS) and Progressive Familial Intrahepatic Cholestasis (PFIC) Registered in the Comprehensive and Informative Registry System for Childhood Liver Disease (CIRCLe)
Run by Takeda · NCT07293897 · Data updated 2026-11-12
This project will look at Japanese patients with Alagille syndrome or PFIC who received maralixibat (Livmarli) to see if taking the drug is linked to liver problems.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are Japanese patients with a recorded diagnosis of ALGS or PFIC who have at least one prescription for Livmarli during the enrollment window.
✕Probably not a fit
Patients without a diagnosis of ALGS or PFIC, those who never received Livmarli, or individuals whose care is not captured in the CIRCLe database would not be included and are unlikely to benefit directly.

What this trial studies
This observational database analysis uses the Comprehensive and Informative Registry system for Childhood Liver Disease (CIRCLe) in Japan to identify patients diagnosed with ALGS or PFIC who were prescribed maralixibat during the enrollment period. The index date is the first prescription of Livmarli, and existing medical records will be reviewed to document occurrences of liver disorders during treatment. No exclusion criteria are specified and the work involves retrospective data analysis rather than new interventions or visits. The project is sponsored by Takeda and aims to estimate the risk profile of maralixibat in a Japanese patient cohort.
Why it matters
Potential benefit: If successful, the study could clarify the risk of liver disorders with maralixibat in Japanese patients and help doctors make safer prescribing decisions.
How similar studies have gone: Clinical trials of maralixibat and other IBAT inhibitors have shown improvements in symptoms like pruritus and bile acid levels in pediatric cholestatic liver disease, but targeted database safety analyses in Japanese ALGS/PFIC patients are relatively limited.
