Filter by:The purpose of this research study is to determine how well an FDA-approved drug, dupilumab, works to treat patients with severe strictures and active Eosinophilic Esophagitis (EoE). This is an open-label study, meaning everyone in the study will receive dupilumab. Participants will have a screening visit where they will complete surveys and undergo an endoscopy (EGD). Blood and biopsies (small tissue samples) will also be collected. If eligible and enrolled into the study, participants will receive weekly subcutaneous (under the skin) injections of dupilumab for 52 weeks (one year). The first dose of dupilumab will be administered at the week 1 visit by a clinician and participants will receive training on how to self-administer the remaining doses. Participants will return for study visits every at weeks 4, 8, 12, 18, 24, 30, 36, 44, and 52. During these visits, vital signs (temperature, heart rate, etc.) will be collected and participants will complete surveys. During visits at week 12, 24, and 52, blood will be collected and an endoscopy with biopsy will be performed. At 64 weeks (12 weeks after the last dose of dupilumab), participants assigned male at birth (AMAB) will be contacted about their / their partner's pregnancy status and participants assigned female at birth (AFAB) may be asked to come for an in-person visit to complete a urine pregnancy test.
The investigator would like to create a prospective cohort of patients in order to describe eosinophilic esophagitis with the specificities corresponding to our geographical territory, and to study their evolution at 3 months, 6 months, 12 months, 18 months and 24 months. This study would also enable us to investigate the quality of life of these chronically ill patients
Feeding dysfunction and/or dysphagia are the main symptoms of eosinophilic esophagitis (EoE). Also, these symptoms may be a part of sensory processing disorders. Therefore, the present study compared sensory processing abilities between children with EoE and typically developing (TD) controls.
Eosinophilic oesophagitis (EoE) is an inflammatory condition of the oesophagus (food pipe) that can lead to difficulty swallowing and to food to getting stuck and has become increasingly common over the past 40 years. EoE is triggered by a protein in the diet but alterations to the types of bacteria (microbiome) in the oesophagus may also be involved. EoE is diagnosed with gastroscopy (a thin camera test via the mouth) where 6 tiny samples (biopsies) are taken. Treatment is either with removing food groups from the diet or medications including steroids (budesonide) or a proton pump inhibitor (PPI, omeprazole). The aim is to improve symptoms and to stop scar tissue forming that can cause food to get stuck. Patients with EoE will need to undergo many gastroscopies over their life, which even with sedation can be a daunting experience. There has been research into less invasive tests and two previous studies have shown that a thin swallowed string may be able to detect substances (biomarkers) that indicate how severe the EoE is. These studies were small and it is not known how the biomarkers change with different treatments or how well they relate to symptoms and findings with endoscopy. In this study the investigators will ask adults with EoE to swallow a thin string made of rayon for 30 minutes, with one end taped to the cheek, which the investigators will analyse for biomarkers and bacteria, on the same day as their routine gastroscopy and also perform a symptom survey. The investigators will also take an extra 2 biopsies to analyse the nerves which may explain why some patients have more symptoms than others. The investigators will repeat the string test on their next endoscopy, to assess what the changes have been in response to their treatments. These findings may improve understanding on how to monitor EoE in less invasive ways in future.
This is parallel, Phase 4 study which consists of a 24 week (0.5 years) randomized, double blind, placebo controlled, 2-arm treatment period followed by an open label segment of 104 weeks (2 years) for a total of 128 weeks (2.5 years) to evaluate the effect of dupilumab treatment on esophageal function, and remodeling in adults with eosinophilic esophagitis. Duration of study period (per participant) - Screening period: Up to 12 weeks before Week 0 - Randomized double-blind period: 24 weeks - Open label period: 104 weeks - Post Investigational Medicinal Product (IMP) intervention follow-up period: up to 12 weeks or until the participants switch to commercialized dupilumab, whatever comes first. There will be ten (10) site visits, and five (5) direct-to-participant IMP delivery visits (except if prohibited by local regulatory authorities or if participant is not willing. In this case, IMP will be dispensed at the study site).
Eosinophilic esophagitis (EoE) is a chronic antigen-mediated inflammatory disease of the esophagus that affects both children and adults. The incidence and prevalence of EoE is rapidly increasing in Western countries with an estimated incidence of 6.6 per 100,000 person-years (95% CI, 3-11.7) in children and 7.7 per 100,000 person-years (95% CI, 1.8-17.8) in adults. Clinically, it is characterized by various symptoms related to esophageal dysfunction, including vomiting, regurgitation, feeding difficulties, epigastric heartburn, dysphagia, or food bolus impaction, and may cause growth retardation. Diagnosis is made on the basis of clinical symptoms and histological evidence of eosinophilic infiltration of the esophagus (at least 15 eosinophils/high power microscope field (eos /hpf), excluding other etiologies of esophageal eosinophilia (gastroesophageal reflux disease, infectious esophagitis, achalasia, celiac disease and Crohn's disease, connective tissue disorders, gra ft versus host disease, drug hypersensitivity and hypereosinophilic syndromes). EoE is primarily characterized by a T helper 2 type inflammation, but the pathogenesis and the immunopathological mechanisms underlying the pathology are not yet fully understood. Recent evidence suggests that in genetically predisposed individuals, interaction with environmental factors (e.g., dietary lifestyle) may play a role in activating several inflammatory pathways and cause EoE. Ultra-processed foods (UPFs) are food and beverage products resulting from industrial formulations, ready for consumption, typically obtained with five or more ingredients from different manufacturing processes (cooking methods, addition of additives such as stabilizers or preservatives). During the last decade, the consumption of the latter has increased significantly among the pediatric population to represent 30% of the daily caloric intake of an average child in Europe and America. Recent evidences show that UPFs favor the onset of chronic non-communicable diseases through the activation of different inflammatory pathways. The components mostly represented in UPFs are the advanced glycation end products (AGEs), a heterogeneous group of highly oxidizing compounds that are formed through non-enzymatic reactions (Maillard reaction) between reduced sugars and free amino groups of proteins, lipids, or nucleic acids. Evidence demonstrates that dietary AGEs are absorbed and contribute significantly to the total concentration of AGEs in the body. AGEs induce oxidative stress and inflammation, leading to structural and functional protein alterations, cellular apoptosis and multi-tissue/organ damage. These mechanisms are mediated at least in part by interactions with their cell-surface receptor for advanced glycation end-products (RAGE). The AGEs-RAGE interaction modulates the immune response. AGEs are able to activate le mast cells, to stimulate the release of histamine and to induce a chronic inflammatory state that promotes a T helper 2 type response.
This is a retrospective monocentric observational study involving patients with Eosinophilic esophagitis (EoE), gastroesophageal reflux disease (GERD), and controls (patients without EoE and GERD). To validate the EoE-related markers obtained with the EoE TaMMA web app (such as CCL26, TBX5, NOX4, FGF7, CXCL14, ADAMTS5, PDGFRA, CXCL12, ACVRL1, POSTN, and LTBP4), we will stain and analyze EoE, GERD, and controls Formalin-fixed paraffin-embedded (FFPE) tissue samples already stored in the pathological laboratory of OSR. For this reason, this project will be accomplished thanks to the collaboration with prof. Doglioni's team at OSR.
Eosinophilic esophagitis is a chronic condition of the esophagus. The symptoms of eosinophilic esophagitis can affect the quality of life of affected children. There is no French scale to specifically evaluate the quality of life of these patients. It will be a monocentric, prospective, descriptive study carried out at the Nice University Pédiatric Hospital. The main objective of this study will be the validation of a French version of the quality of life pediatric scale (PedsQL) module for eosinophilic esophagitis. It will take place in 2 distinct parts: - The translation of the questionnaire in French. - Collection of the quality of life questionnaires
Eosinophilic Esophagitis (EoE) is a immuno-mediated disease, characterised by a Th-2 food-antigen driven chronic inflammatory response of the esophagus. Main symptoms are dysphagia and food bolus impaction, frequently overlapping with most atypical and general symptoms like heartburn or regurgitation and difficulty to thrive in children. Overall incidence and prevalence of EoE are rapidly increasing. The complete comprehension of pathogenetic and molecular mechanism underlying this complex and relatively new disease is still to be conquered. For this reason, we created this EoE Biobank, in order to collect blood, oral and esophageal tissue samples of proven EoE patients to further exploit new insights of this disease.
The study is researching an experimental drug called dupilumab. The study is focused on participants with active eosinophilic gastritis (EoG) with or without eosinophilic duodenitis (EoD). Participants with EoD only are not eligible for enrollment. EoG and EoD are uncommon, persistent, allergic/immune diseases in which eosinophils (a type of white blood cell) gather in large numbers in the stomach and small intestine and cause inflammation and damage. The aim of the study is to evaluate the effect of dupilumab on relieving EoG (with or without EoD) symptoms and reducing inflammation in the stomach and, if applicable, small intestine in adults and adolescents aged 12 years and older, compared to placebo. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in your blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
