Active clinical trials for "Protein-Losing Enteropathies"

The primary objective of the study is to determine the effect of pozelimab on active CD55-deficient protein-losing enteropathy (PLE; CHAPLE). The secondary objectives of the study are: To evaluate the safety and tolerability of pozelimab in patients with CD55-deficient PLE disease To evaluate the effect of pozelimab on CD55-deficient PLE (both patients with active disease at baseline and those with inactive disease on eculizumab, switching to pozelimab) To determine the effects of pozelimab on albumin and other serum proteins (total protein, immunoglobulins) To determine the effects of pozelimab on ascites To determine the effects of pozelimab on stool consistency To determine the effect of pozelimab on health-related quality of life To determine the effect of pozelimab on lab abnormalities observed in CD55-deficient PLE such as hypertriglyceridemia, thrombocytosis, and hypovitaminosis B12 To describe the effects of pozelimab on the sparing of concomitant medications and reduction in hospitalization days To determine the effects of pozelimab on growth To characterize the concentration of pozelimab in patients with CD55-deficient PLE To assess the incidence of treatment-emergent ADA for pozelimab in patients with CD55-deficient PLE disease

Plastic bronchitis (PB) is a rare, most often pediatric disease characterized by the formation of obstructive airway casts primarily composed of fibrin. There is presently no FDA-approved pharmacotherapy for PB, but acute exacerbations of the illness are often treated with inhaled tissue plasminogen activator (tPA). To date, this is done somewhat anecdotally because there has been no safety or efficacy testing of this treatment. In addition, there is presently no reliable surrogate marker of adverse drug events. Nevertheless, in the absence of inhaled tPA treatment, PB-induced respiratory distress can be severe, often warranting urgent or emergent bronchoscopy for cast removal, or can sometimes result in respiratory failure. As such there is a significant unmet need for safety and efficacy testing of inhaled tPA and for biomarkers of drug response. Objectives and Endpoints: The objectives of this protocol are to: 1) test the safety and efficacy of an inhaled tPA regimen in children with PB; and 2) identify potential candidate biomarkers of inhaled tPA drug response. Safety endpoints will consist of the development of new, active bleeding that is systemic and/or pulmonary and/or new hematuria (defined as gross hematuria). Secondary endpoints of efficacy will also be measured (e.g., frequency of cast production). Urine and blood will also be collected for the development of potential biomarkers of inhaled tPA drug response. Funding source- FDA OOPD

This study is phase 2 open-label, single-arm, multi-center clinical trial to evaluate the efficacy and safety of Camostat mesylate in patients with Protein-losing enteropathy after Fontan operation.

Patients that have undergone a Fontan procedure (surgical correction for single ventricle congenital heart disease) may develop a complication known as protein-losing enteropathy (PLE). Some studies suggest PLE is primarily caused by impaired lymph flow. Use of continuous dopamine infusion can improve PLE. Evidence suggests the effect of dopamine may be through its effect on lymphatic function. This observational study looks at markers of lymph flow and PLE symptoms after treatment using dopamine and other standard therapies during disease exacerbations.

Protein Losing Enteropathy (PLE) is a serious medical condition that may develop in children and adults with congenital heart disease for which a palliative procedure known as the "Fontan procedure" has been performed. The loss of serum proteins into the gastrointestinal tract that is associated with PLE can cause serious symptoms and life-threatening complications. A number of clinical studies have suggested that heparin administration can have clinical benefit in children with PLE, however the risk of bleeding associated with the administration of heparin is an important concern and commonly limits its administration. ODSH is a desulfated heparin with minimal anticoagulation properties but which, in pre-clinical studies, appears to have the potential to replace heparin and greatly reduce the risk of bleeding. This open label study is to assess the safety and evidence of therapeutic effect of the administration of ODSH as a 4-day continuous intravenous infusion in patients with an exacerbation of their PLE.

The investigators are studying what causes Plastic Bronchitis and Protein Losing Enteropathy. The investigators think that these problems are from too much of two small proteins called Vasoactive Intestinal Peptide (VIP) and Substance P. VIP and Substance P are important proteins in the body that normally tell the body to make small amounts of fluid and they help the intestines work. Normally, VIP and Substance P are made in the intestines and then destroyed in the lungs after they do their normal work. The investigators think that kids who have Plastic Bronchitis and/or Protein Losing Enteropathy who also had the Fontan surgery might have too much VIP and Substance P in their bodies. The investigators think this causes too much fluid to go in the lungs and too much protein in the intestines.

The program is to provide access to an experimental drug called pozelimab and to document the long-term safety of pozelimab in patients with Protein-Losing Enteropathy (PLE). CD55-deficient PLE/CHAPLE disease is a rare inherited disease of the immune system. This can be a life-threatening condition that is usually found when patients are children.

The Fontan procedure has revolutionized the treatment of patients born with a congenital univentricular heart defect. However, over time, it is associated with severe lymphatic complications such as plastic bronchitis, protein-losing enteropathy (PLE) and peripheral edema. The hypothesis is that patients with a univentricular circulation have a changed morphology which may be associated with both the degree of lymphatic complications and their physical capacity. The morphology will be described using T2-weighted non-contrast MRI.

The aim of the current study is to investigate if there is GIT involvement in pt's with SLE particularly protein losing enteropathy also its prevalence among the studied cases and it's relation to disease activity .

CHAPLE syndrome (complement hyperactivation, angiopathic thrombosis, protein losing enteropathy) is a newly discovered genetic disorder, which is caused by deleterious mutations in the CD55 gene. Patients often suffer from chronic manifestations that may lead to life-threatening complications despite conventional treatment options.The cause of gastrointestinal protein loss is distorted lacteals in the gut, referred to as primary intestinal lymphangiectasia (PIL). There is a second group of patients with PIL with intact CD55, referred to here as "non-CHAPLE PIL". The current study aims to explore the signatures of CHAPLE and non-CHAPLE PILs, discover druggable molecular targets and identify biomarkers that can direct therapy. A subgroup of patients with CHAPLE syndrome receive treatment with a complement C5 blocker, eculizumab, on an off-label basis. This study involves serial transcriptome and metabolic profiling of biological samples under eculizumab therapy and correlates them with the clinical response. Overall, the aim of this research is to integrate clinical data and high-throughput metabolic profiling approaches to better characterize the etiology of PILs and develop novel therapeutic approaches.
