Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this 5-year, prospective, observational cohort study is to evaluate the long-term safety and clinical outcomes of patients with Alagille syndrome (ALGS) or Progressive familial intrahepatic cholestasis (PFIC) treated with Livmarli.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Livmarli® is a novel, minimally absorbed, pharmacological product that inhibits the ileal bile acid transporter (IBAT) in the terminal ileum, leading to reduced levels of bile acids. Livmarli (maralixibat) has been developed by Mirum Pharmaceuticals and was the first treatment approved by the US Food and Drug Administration (FDA) for the treatment of cholestatic pruritus in patients 3 months of age and older with Alagille syndrome (ALGS). Subsequently, Livmarli was approved by the FDA for the treatment of cholestatic pruritus in patients 12 months of age and older with Progressive familial intrahepatic cholestasis (PFIC). To be eligible for the study, participants must meet the following criteria:

* A clinically and/or genetically confirmed ALGS diagnosis or PFIC diagnosis
* Prescribed Livmarli
