Likely a good fit

Ideal candidates for this study are patients with a clinically and/or genetically confirmed diagnosis of Alagille syndrome or Progressive familial intrahepatic cholestasis who have been prescribed Livmarli.

Probably not a fit

Patients who have previously participated in a clinical study involving Livmarli or have received an investigational drug within 30 days prior to the study 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 is a 5-year, prospective, observational cohort study aimed at assessing the long-term safety and clinical outcomes of patients diagnosed with Alagille syndrome (ALGS) or Progressive familial intrahepatic cholestasis (PFIC) who are treated with Livmarli. Livmarli is a novel medication that works by inhibiting the ileal bile acid transporter, thereby reducing bile acid levels in the body. The study will include participants who have a confirmed diagnosis of ALGS or PFIC and are prescribed Livmarli, allowing researchers to gather data on its effectiveness and safety over time.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and efficacy of Livmarli, potentially improving treatment options for patients with ALGS and PFIC.

How similar studies have gone: Other studies have shown promising results with similar approaches in treating cholestatic liver diseases, but this specific observational study is novel in its long-term focus on Livmarli.
