Active clinical trials for "Alagille Syndrome"

Double-blind, randomized, placebo-controlled, Phase 3 study to investigate the efficacy and safety of odevixibat compared to placebo in Patients with Alagille Syndrome.

The primary objectives of the study are to evaluate the safety, tolerability and pharmacokinetics of A4250 after single or multiple oral doses in healthy subjects. In addition, will evaluate A4250 in combination with cholestyramine.

The purpose of this extension study is to determine the long-term safety and tolerability of an investigational treatment (LUM001 also known as Maralixibat) in children with ALGS who have completed participation in a core LUM001 treatment protocol. Efficacy will be assessed by evaluating the effect of LUM001 on pruritus, biochemical markers of pruritus, as well as biochemical markers of cholestasis and liver disease.

This is a long-term, open-label study with a double-blind, placebo-controlled, randomized drug withdrawal period in children with Alagille Syndrome (ALGS) designed to evaluate the safety and efficacy of LUM001 (Also known as maralixibat or MRX).

OBJECTIVES: I. Determine the role of magnesium deficiency in the pathogenesis of decreased serum vitamin D and reduced bone density in children with chronic cholestatic liver disease.

Noninvasive monitoring of liver fibrosis is an unmet need within the clinical management of pediatric chronic liver disease. While liver biopsy is often used in the initial diagnostic evaluation, subsequent biopsies are rarely performed because of inherent invasiveness and risks. This study will evaluate the role of non-invasive FibroScan™ technology to detect and quantify liver fibrosis.

The primary objectives of the study are to assess the mass balance recovery after a single dose of carbon-14 [14C]-A4250 as a capsule and to provide plasma, urine and faecal samples for metabolite profiling and structural identification in healthy male subjects.

Patients who have Alagille Syndrome (AGS) also frequently have blockages (or "stenoses") of their pulmonary arteries. Little is known about the degree or variability of these stenoses, or the effect of this disease on the right ventricle (the chamber of the heart which pumps blood to the lungs). This study will first quantify and describe pulmonary artery stenosis in patients with Alagille Syndrome. The study will also assess the effect of these stenoses on the right ventricle. The investigators hope to learn the degree and characteristics of pulmonary artery stenosis in Alagille Syndrome. The investigators also hope to learn the effect of this pulmonary artery stenosis on the right ventricle in patients with Alagille Syndrome. This information is critical in the management of patients with Alagille syndrome, as there is currently no data to guide clinicians on the management of pulmonary artery stenosis. Furthermore, the information from this study may help physicians manage pulmonary artery stenosis in other patients as well.

The purpose of the study is to validate the ItchRO instrument (a clinical outcome assessment measure of itching) prior to the analysis of longitudinal treatment effect data being generated in ongoing clinical trials.

The goal of the project is to identify and clone the gene(s) responsible for the Alagille Syndrome (AGS) by a positional cloning approach. The first step towards this goal is to define the smallest genomic candidate region for AGS at 20p12 and to begin to identify genes within this region which are, by definition, candidate genes for the disease. In a collaborative effort with clinician-investigators studying the Alagille syndrome, metaphase chromosomes and genomic DNA from affected individuals will be studied for subchromosomal deletions and for mutations in the candidate genes. Characterization of genes involved in Alagille syndrome could provide important insight into the pathophysiology of the disease, the development of normal liver and treatment of this disease. Recently, we and others found that mutations in Jagged1, a Notch1 receptor are responsible for Alagille Syndrome.
