Active clinical trials for "Cholangitis, Sclerosing"

Primary sclerosing cholangitis (PSC) is an idiopathic condition with intrahepatic cholangitis and fibrosis, leading to multifocal bile duct stricture. Its main clinical manifestations are chronic cholestatic lesions and is deemed as autoimmune liver disease. PSC are immune abnormalities that occurs in patients with genetic susceptibility. No other pathogenesis is revealed yet. Ursodeoxycholic acid is used as an empirical treatment, and there is no approved drug or a acceptable treatment regimen. The disease often progresses to liver decompensation and requires liver transplantation. In recent years, the clinical application of stem cell therapy has seen many important advances. Stem cells are characterized with properties of multiple differentiation, repair of damaged tissue and immuno-modulation. This study aims to employ UCMSCs to treat PSC patients and observe its efficacy and safety, and to explore the possible therapeutic mechanisms.

A Phase 2a, multicenter, randomized, double-blind, dose-ranging, placebo-controlled, study to evaluate the safety, tolerability, and PK of PLN-74809 in participants with primary sclerosing cholangitis and suspected liver fibrosis

Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine. Bile is a liquid produced by the liver that helps us absorb and use the nutrients in the food we eat. In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: Collect medical and other data to learn more about PSC, how it progresses, and identify factors that may cause the disease to progress more quickly. Ask questions about how PSC symptoms affect your child's life to learn more about its impact on your child's daily functioning Children with PSC who are seen at one of the participating clinical sites in the Childhood Liver Disease Research Network (ChiLDReN) will be asked to contribute information, DNA, and other specimens. The information and specimens will be available to investigators to carry out approved research aimed at learning more about the possible causes and long-term effects of PSC.

Autoimmune liver diseases (AILD), which include Primary Sclerosing Cholangitis (PSC) and Autoimmune Hepatitis (AIH) are a common etiological factor for chronic liver disease among adolescents. This is a longitudinal study to identify surrogate endpoints with an accurate predictive value for the progression of hepatobiliary damage in subjects with pediatric onset AILD. This study will involve collection of MRI-based data at the time of enrollment and at year 1 and 2 of follow up, and collection of clinical data for 10 years following enrollment. There is a strong possibility that MRI quantitative techniques may be more sensitive to disease progression than standard clinical and laboratory tests. To investigate predictivity of MRI based biomarkers, summary measures of MRCP/MREL from baseline, Year 1 and Year 2, e.g. change rate, maximum, and average will be calculated as predictors for Year 10 clinical outcomes. The same predictors will also be used to model native liver survival in a proportional hazard regression. Findings from this study may be used to assess disease progression and to predict complications and survival of liver disease patients.

Primary sclerosing cholangitis (PSC) a rare, chronic fibroinflammatory disease of the liver. No data about the disease epidemiology exist in Italy. Therefore this study aims to develop a national PSC patient database linked to a biological sample storage.

Primary sclerosing cholangitis (PSC) is a chronic liver disease that can lead to liver cirrhosis, liver failure and liver cancer. Assessment of disease status is important to determine optimal treatment but the diagnosis of PSC is challenging. There is a dire need of an accurate non-invasive tool for longitudinal assessment of PSC. MR Elastography (MRE) has been recently proven to estimate liver fibrosis noninvasively and accurately. Estimation of liver fibrosis by MRE along with imaging derived morphological information (MRCP) will be utilized in this study comprehensively to provide a surrogate non-invasive imaging biomarker for monitoring disease status in PSC. Successful outcomes will provide an opportunity for optimal treatment triage including liver transplantation via accurate and non-invasive estimation of true disease status in PSC.

Background: Primary sclerosing cholangitis is a rare chronic liver disease. It affects the bile ducts of the liver. It can result in bile duct infections, cirrhosis, cancer, and end stage liver disease. Researchers want to learn more about this disease. Objective: To understand the biological causes of primary sclerosing cholangitis. Eligibility: Adults age 18 and older who have primary sclerosing cholangitis. Design: Participants will be screened with a medical history, physical exam, and blood tests. Participants will give blood, saliva, urine, and stool samples. They will have nasal swabs. They will complete surveys. Participants will get an intravenous (IV) catheter. A plastic tube is inserted into an arm vein. Participants will have a colonoscopy. A tube with a video camera at the end is inserted into the rectum. Participants will have an upper endoscopy. A scope with a light and camera at its tip is used to look inside the upper digestive tract. Participants will have a liver biopsy, entering through the chest wall or a neck vein. Blood is drawn from a blood vessel that carries blood to the liver. A liver tissue sample is taken. Participants will have magnetic resonance imaging or spectroscopy. They will get a contrast agent through an IV. Participants may have an optional bone marrow aspiration. A large needle is inserted into the hip to withdraw marrow. Participants will have a liver ultrasound. Participants will complete a 3-day food diary. They will have a nutrition assessment. Participants may give contact details for people who live with them, to also take part in this study. Participation will last for 12 months....

Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). Although rare, PSC is associated with significant and disproportionate unmet needs; with heightened risks of colorectal cancer and colectomy, and greater all-cause mortality rates compared to matched IBD patients. Unfortunately, no medical therapy has been proven to slow disease progression in PSC-IBD, and liver transplantation is the only lifesaving intervention for patients. The strong association between PSC and IBD has led to several pathogenic hypotheses, in which dysregulated mucosal immune responses are proposed to contribute. Of note, the investigators recently identified distinct mucosal transcriptomic profiles in PSC-IBD; with regards bile acid metabolism, bile acid signalling, and a central role of enteric dysbiosis. In parallel, pilot data from other groups have shown that treatment with oral vancomycin (a non-absorbable, gut-specific antibiotic) attenuates colonic inflammation and improves biochemical markers of cholestasis in PSC. However, there is no mechanistic data exploring the host-microbial alterations under vancomycin treatment in PSC-IBD, neither the impact of vancomycin on bile acid circulation. The investigators of this study hypothesize that oral vancomycin attenuates colonic mucosal inflammation in PSC-IBD, by restoring gut microbiota mediated bile acid homeostatic pathways. Through these means the study aims to identify druggable gut microbial and host molecular pathways associated with bile acid mediated colonic mucosal inflammation in PSC-IBD.

The Autoimmune Liver disease Network for Kids (A-LiNK) is a multi-institutional group with the mission to deliver the best care to kids with pediatric autoimmune liver disease (AILD). This study will establish a shared clinical registry and a learning health network for the participating sites focusing on collecting and transmitting clinical measurement data, information about processes, and participation in an improvement collaborative. Pediatric Autoimmune Hepatitis (AIH) and Primary Sclerosing Cholangitis (PSC), represent a spectrum of AILD which present unique diagnostic and therapeutic challenges.A lack of accepted guidelines for disease monitoring or symptom management results in wide treatment variation with liver transplants indicated in refractory, progressive disease. The aims of A-LiNK are to: 1.) Create a learning health network focused on patient-centered outcomes research characterized by transparent sharing among centers, common priorities, and feasible plans for implementing new practices; 2) shift from traditional investigator-driven study to a patient and family-centered approach, and 3.) improve clinical outcomes and quality of life for pediatric AILD patients.

This study is a clinical trial being done to investigate the efficacy of drug BRS201 as a treatment in patients with primary sclerosing cholangitis. Participation in this study will take 8 weeks long and the study is structured as a cross-over study in which participants will take the study drug for 4 weeks and a placebo drug for 4 weeks in a randomized order in the form of an oral medication. Participation may also involve receiving an IV dose of the medication. The study will require participants to attend 9 study visits, all of which will be remote. Participation will involve taking an oral medication twice daily, tracking the medication in a log, and getting blood drawn and giving a stool sample for a few lab tests throughout the study. For the lab tests, a research nurse will visit the participant in-home for the convenience of the participant.
