NCT07411716
The purpose of this study is to create a national, multi-centre registry for children with Alagille syndrome (ALGS) and Genetic Intrahepatic Cholestasis (GIC) that follows participants long-term, ensuring standardized, high-quality data capture across all participating pediatric hepatology centres. Inclusion criteria: • Pediatric participants (\<18 years old) with genetically confirmed or clinically diagnosed ALGS or any of the various subtypes of GIC, each associated with a distinct genetic mutation: A. PFIC Type 1 (FIC1 Deficiency) - Mutation in ATP8B1 gene. B. PFIC Type 2 (BSEP Deficiency) - Mutation in ABCB11 gene. C. PFIC Type 3 (MDR3 Deficiency) - Mutation in ABCB4 gene. D. PFIC Type 4 (TJP2 Deficiency) - Mutation in TJP2 gene. E. PFIC Type 5 (FXR Deficiency) - Mutation in NR1H4 gene. F. PFIC Type 6 (MYO5B-Associated) - Mutation in MYO5B gene. G. Progressive cholestasis of northwestern Quebec (PCNQ)-Mutation in UTP4 gene. * Enrollment within Canadian pediatric liver centers participating in the registry. * Written informed consent obtained from participant if they have the capacity, or parents/guardians, and assent from participants as appropriate. Exclusion criteria: • Inability to comply with follow-up requirements (lost to follow-up). Participants will be recruited from our hepatology clinics retrospectively (diagnosed on or after January 1, 2022) and prospectively (newly diagnosed). Written consent/assent will be obtained from all participants prior to data collection from the participants' medical chart.
NCT07293897
This study is a database study in Japan for maralixibat (TAK-625) used to treat participants with Alagille Syndrome (ALGS) and Progressive Familial Intrahepatic Cholestasis (PFIC). The main aim of the study is to evaluate the risk of liver disorder during the use of maralixibat in Japanese patients with ALGS or PFIC. This database study will conduct in use of medical database called Comprehensive and Informative Registry system for Childhood Liver Disease (CIRCLe).
NCT05543174
The main aim of the study is to check if TAK-625 improves symptoms of Alagille Syndrome (ALGS), side effect from the study treatment or TAK-625, and how much TAK-625 stays in their blood over time. This will help the study sponsor (Takeda) to work out the best dose to give people in the future. The participants will be treated with TAK-625 for up to the end of study (about 34 months). Participants will visit their study clinic 9 times from the start of study. After 9 times visits, participants will visit their study clinic every 12 weeks up to the end of study.
