What this Trial Is About

Researchers are evaluating the long-term safety, tolerability, and effectiveness of Livmarli treatment in patients diagnosed with either Alagille Syndrome (ALGS) or Progressive Familial Intrahepatic Cholestasis (PFIC). The study focuses on monitoring possible liver toxicity and, for PFIC patients, the potential impact of prolonged exposure to propylene glycol. This open-label, low-intervention trial aims to collect clinical outcomes over an extended period to better understand the treatment's effects. Participants will receive Livmarli as part of their standard care throughout the study. The trial includes a primary cohort of at least 45 treatment-naïve ALGS patients and a supplemental ALGS cohort already using Livmarli. Additionally, a minimum of 130 PFIC patients treated with Livmarli will be enrolled. Treatment and assessments follow a defined schedule during the study period. Participants will undergo regular evaluations every 3 to 4 months for up to 5 years, including liver function tests, fat-soluble vitamin levels, international normalized ratio measurements, and monitoring of propylene glycol toxicity for PFIC patients. Adverse events are tracked up to 7 days after the last dose. Researchers will assess long-term clinical outcomes to understand treatment impact, with participants continuing their care according to standard practice during the study.
