Brief summary

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

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

Interventions

DRUGLivmarli

The recommended dosage is 380 mcg/kg once daily.

MeasureTime frameDescription
Incidence of Long-Term Clinical OutcomesLong-term clinical outcomes (SBD, LT, portal hypertension, all-cause mortality) up to 180 days after discontinuation of Livmarli will be recorded.The dates, and reasons for the following first events (of this first endpoint) will be collected: Surgical Biliary Diversion (SBD), Liver Transplant (LT), and all-cause mortality. In addition, manifestations of clinically evident portal hypertension (CEPH) will be captured during each interval event assessments.
Liver Transplant Indication and Waitlist StatusLT waitlist status will be collected at enrollment and every 6 months for 5 years.LT waitlist status will be collected, including when placed on or removed from LT waitlist.
Assessment of Growth and DevelopmentWeight (kilograms) and height (centimeters) z-scores will be collected every year for 5 years.Height and weight will be collected both at the time the participant started Livmarli and at the time of enrollment in the study. Subsequent weight will be collected for up to 5 years. Weight z-score (kilograms) and height z-score (centimeters) will be assessed and reported every year for 5 years.
Incidence of Clinical Events Potentially Related to Fat-Soluble Vitamin Deficiencies and Their Long-Term SequelaeThe incidence of events will be assessed and reported every year for 5 years.Bleeding events (including all gastrointestinal \[GI\] or non-GI bleeding requiring hospitalization, emergency department care, or transfusion) and fracture events will be reported.
