Data and Sample Collection Study to Elucidate the Mechanisms of Eosinophilic Disorders
The purpose of this study is to elucidate the mechanisms underlying eosinophil growth, survival, migration, and function and to investigate and further characterize the pathophysiology of, clinical manifestations of, and spectrum of disease severity of eosinophilic inflammation in humans.
Determine Immunoglobulin G4 (IgG4) Standards for Cow's Milk and Egg in Different Populations of Allergic and Non-allergic Children
The study objectives are : Determine standards of plasma levels of casein-specific immunoglobulin G4 (IgG4) and egg-specific immunoglobulin G4 (IgG4) as a function of age, in non-allergic children, in allergic children, and in cured former allergic patients. Analyze the plasma IgG4 / IgE ratio, according to the result of the oral provocation test (tolerance versus allergy) and, in the event of a reaction, according to the reactogenic dose (dose which caused the reaction).Determine whether analysis of the plasma metabolome can identify children with a cured allergy to cow's milk protein or to egg from those with a ...
Diagnostic Accuracy and Safety of DBV1605 for the Diagnosis of Non-IgE Mediated Cow's Milk Allergy in Children
Study to assess the diagnostic accuracy (sensitivity, specificity, positive and negative predictive value) of DBV1605 for the diagnosis of non-Immunoglobulin E (IgE) mediated cow's milk allergy (CMA) in children with symptoms suggestive of non-IgE mediated CMA.
Do Patients With Fish or Shellfish Allergy Tolerate the Consumption of Fish Oil Supplements? A Clinical Study
The purpose of this clinical study is to test whether patients with fish or shellfish allergy can ingest different types of fish oil supplements without having an allergic reaction. To achieve this, the recruited participants will be asked to: - provide a blood sample (used for Basophil Histamine Release Assay) - undergo a skin-prick-test - partake in multiple oral provocations These three tests will indicate the likelihood that the participants can consume fish oil supplements without adverse allergic reactions (See the detailed description for an explanation of the tests). The investigators will...
Dose Escalation Study to Evaluate an Experimental New Treatment (CALY-002) in Healthy Subjects and Subjects With Celiac Disease and Eosinophilic Esophagitis
This is a single and multiple ascending study to characterize the safety, PK, PD and clinical effect in healthy volunteers and participants with Celiac Disease and Eosinophilic Esophagitis.
Dupilumab and Milk OIT for the Treatment of Cow's Milk Allergy
This is a phase 2, multicenter, randomized, double-blind, parallel group, 2 arm study in approximately 40 subjects aged 4 to 50 years, inclusive, who are allergic to cow's milk. The primary objective is to assess whether dupilumab as an adjunct to milk oral immunotherapy (OIT) compared to placebo improves the safety of milk OIT and rates of desensitization, defined as an increase in the proportion of subjects who pass a double-blind placebo-controlled food challenge (DBPCFC) to at least 2040 mg cumulative milk protein at week 18.
Dupilumab in Eosinophilic Gastritis
40 participants with Eosinophilic Gastritis 12-70 years of age will be randomly assigned with dupilumab or placebo subcutaneous injections every two weeks for a total of 12 weeks. Study subjects who complete the 12-week treatment phase, may continue into an open label extension study, where dupilumab will be administered every two weeks for a total of 24 weeks.
Effect of Personalized Elimination Diet on Food Sensitivity Related Symptoms
The goal is to identify food sensitivity in patients and assess whether the avoidance of the reaction-inducing foods via an 'elimination diet' leads to improvement in patient symptoms and overall well-being.
Efficacy and Safety of QGE031 (Ligelizumab) in Patients With Peanut Allergy
This is a 52-week, Phase 3 multi-center, randomized, double-blind and placebo-controlled study to assess the safety and clinical efficacy of two dosing regimens of ligelizumab (240 mg and 120 mg) subcutaneous injection every 4 weeks (SCq4w) in participants with a medically confirmed diagnosis of IgE-mediated peanut allergy.
Efficacy and Safety of Tezepelumab in Patients With Eosinophilic Esophagitis
A randomized, double-blind, placebo-controlled multicenter, phase 3 study to evaluate the efficacy and safety of tezepelumab administered subcutaneously (SC) using an accessorized pre-filled syringe (APFS) versus placebo in adult and adolescent patients with eosinophilic esophagitis (EoE).
