A Study Assessing Esophageal Function and Remodeling With Dupilumab Compared With Placebo for 24 Weeks Followed by 104 Weeks Open Label in Adult Participants With EoE (REMOdeling With Dupilumab in Eosinophilic Esophagitis Long-term Trial)
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...

A Trial to Evaluate EP-104IAR in Adults With Eosinophilic Esophagitis (EoE).
An open-label, dose-escalation study to explore the safety, tolerability and pharmacokinetics of EP-104IAR in adults with eosinophilic esophagitis (EoE). Endoscopic and histologic assessments will also be evaluated to understand the local effects of EP-104IAR on eosinophilic EoE disease activity. The study will evaluate up to 8 doses of EP-104IAR (4 mg to 40 mg) in cohorts of 3 to 6 participants per cohort. If all planned cohorts are evaluated, or cohorts need to be repeated, up to 24 participants could be enrolled. The study involves 7 site visits spread over approximately 32 weeks. All participants will receive active...

A Trial to Learn if Dupilumab is Safe for and Helps Adult and Adolescent Participants With Eosinophilic Gastritis With or Without Eosinophilic Duodenitis
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 ...

BAT Cow's Milk for the Replacement of the Food Challenge Test
The prevalence of children suspected of a cow's milk allergy is 17% in the Netherlands. Cow's milk diagnosis is based on a food challenge test However, this food challenge test is expensive, time consuming, risky, with waiting lists of several months. This waiting time results in unnecessarily long-term use of expensive hypoallergenic milk formula Therefore, there is a great need to introduce a better and faster diagnostic test for cow's milk allergy diagnosis in standard care. The in vitro Basophil Activation Test (BAT) is cheap, quick (result < 1 day, no waiting list), safe for the child and is a reliable alternative for the food...

Blood Samples for the Study of Peanut, Tree Nut and Other Food Allergies
Food allergies are now a major problem. These experiments involve getting blood from people with food allergies and from people without food allergies. The blood collected will be used to answer questions and find information about peanut and other food allergies. Samples will come from: - People signed up by the investigators at the University of Colorado Denver - University of North Carolina, Massachusetts General Hospital, Children's Hospital of Colorado and the Immune Tolerance Network (Benaroya Research Institute) where people have been treated for peanut allergies - University of North...

Boiled Tree Nut for Oral Immunotherapy in Food-allergic Children
As the global prevalence of food allergy steadily increases, tree nut (TN) becomes one of the main triggers of food-allergic reactions and food anaphylaxis. Since there is no effective cure, TN-allergic patients and their families must continue to live with this chronic, disabling condition while avoiding allergens and responding to allergic reactions with emergency treatment. An emerging experimental treatment for food allergy is oral immunotherapy (OIT). Tree nut OIT appears promising in preliminary studies but there are concerns about the high risk of adverse reactions to TNs used in the treatment. The rate of remission with TN...

Brachyspira and Intestinal Allergy-like Immune Reactions in Patients With Irritable Bowel Syndrome (IBS)
The aim of this study is to define local immune responses in the GI tract to food antigens in IBS patients, with and without Brachyspira infection, using advanced imaging. We hypothesize that Brachyspira infection can cause IBS symptoms by inducing loss of oral tolerance to dietary antigens through development of food-specific intestinal immune reactions and subsequent development of visceral hypersensitivity. During this study, the investigators will perform either confocal laser endomiscroscopy (CLE) or colonoscopic antigen provocation test (COLAP) to test to which food items the participants react to. Furthermore, the...
