Active clinical trials for "Biliary Atresia"

The purpose of this study is twofold. First, is to determine whether vancomycin is effective in the early treatment of Biliary Atresia (BA) and Primary Sclerosing Cholangitis (PSC), and if so, by what mechanism. Secondly, to characterize human intestinal microbial communities and their interactions with the host.

the study of the effect o the hanging of the jejunal loop to the peri KPE Glisson capsule on the rate of bile drainage and requirement of liver transplantation

The Investigators propose to test the hypothesis that GCSF enhances the clinical outcome of biliary atresia in a multi-institutional Phase 2 trial to prospectively evaluate the safety and efficacy of GCSF in each of the 2 groups of newly diagnosed BA patients: KBA (i.e., Kasai-operated) or NoK (i.e., patients who did not undergo Kasai surgery). Subjects who participate in the trial will be followed for 2 years.

Double-blind, randomized, placebo-controlled, Phase 3 study to investigate the efficacy and safety of odevixibat compared to placebo in children with biliary atresia who have undergone a Kasai hepatoportoenterostomy.

This study aims to assess the efficacy and safety of prophylactic intraoperative norepinephrine infusion versus the standard technique on decreasing the incidence of intraoperative hypotension in infants undergoing Kasai portoenterostomy operation.

An Open-label Extension Study to Evaluate Long-term Efficacy and Safety of Odevixibat (A4250) in Children with Biliary Atresia

This study is a prospective, single-center, randomized controlled, parallel, and open clinical study.

Although considered a rare disease, Biliary Atresia (BA) is the leading cause of neonatal cholestasis and liver transplantation in children. Little is known about the molecular mechanisms that drive BA. The purpose of this study is to collect the fluid samples, explanted liver tissue samples and dermal biopsy samples to enable investigators to perform the genetic and molecular analyses that might point to the gene(s) and cellular pathway involved in etiology of BA disease.

A study to evaluate the efficacy and safety of maralixibat in infants with Biliary Atresia (BA) after Hepatoportoenterostomy (HPE, also known as the Kasai procedure).

Biliary atresia (BA) is a devastating liver disease of infancy, characterized by bile duct obstruction leading to liver fibrosis, cirrhosis, and eventual need for transplantation in most cases. BA is treated with Kasai portoenterostomy (KP). KPs can achieve bile drainage and improve outcomes. However, even with standard evidence of "good bile flow," bile flow rarely normalizes completely and liver disease continues to progress. In this study, the investigators test whether intravenous N-acetylcysteine (NAC) can improve bile flow after KP. The rationale is that NAC leads to synthesis of glutathione, which is a powerful stimulator of bile flow. The primary objective is to determine whether NAC normalizes total serum bile acid (TSBA) concentrations within 24 weeks of KP. Achieving normal TSBAs is uncommon with current standard-of-care, and is predicted to be associated with better long-term outcomes. The secondary objectives are to describe how other parameters commonly followed in BA change with NAC therapy, as well as report adverse events occurring with therapy and in the first two years of life. This study follows the "minimax" Phase 2 clinical trial design.
