Efficacy and Safety of Benralizumab in Patients With Eosinophilic Gastritis and/or Gastroenteritis (The HUDSON GI Study)
This is a 3-part study. Part A and B have identical designs and are randomized, double-blinded, placebo-controlled studies, which will include patients with eosinophilic gastritis and/or duodenal-only disease. Part A will be enrolled first, followed by Part B. After completing Part A or Part B, participants will continue to Part C - open-label benralizumab treatment period.
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 Three Doses of Florence Oral Suspension in Adults With Eosinophilic Esophagitis
The purpose of this study is to evaluate the efficacy of three doses of Florence oral suspension on changes of eosinophilic infiltration in esophageal biopsies.
Efficacy of Low-Dose Topical Steroids in Maintaining Remission of Eosinophilic Esophagitis in Children
This study evaluates the decrease in steroid dosing for patients who have achieved remission on a full dose of steroids. Once a patient is in remission they will be enrolled in this study if they choose to decrease the steroid dosing.
Egg Allergy Oral Desensitization
This study evaluates whether tolerance to eggs can be induced in patients through a process of oral immunotherapy. Participants will be randomized into groups receiving oral immunotherapy and a control group that will receive no intervention
EoE Food Desensitization
This is a single-center, prospective, pilot clinical trial in which children ages 3-17 years with eosinophilic esophagitis (EoE) who have a known food that triggers EoE flares receive oral desensitization with that specific food antigen, followed by reintroduction of that food into the diet. The purpose of this study is to investigate the safety and feasibility of oral desensitization in children with EoE so that, if determined to be safe, can be repeated on a larger scale to determine efficacy.
EoE RCT Fluticasone and Omeprazole vs Fluticasone Alone
The purpose of this study is to evaluate the efficacy of combination therapy with omeprazole and swallowed fluticasone vs fluticasone therapy and placebo in the treatment of Eosinophilic Esophagitis (EoE) in children and adults. This study will be a double-blinded, randomized controlled trial. The primary outcome measured will be histologic assessment of esophageal tissue biopsies measuring number of eosinophils per high power field (eos/hpf). Secondary outcomes will be endoscopic findings and symptomatic changes following therapy using validated endoscopic scoring measures and participant surveys, respectively.
Eosinophilic Esophagitis Steroid Safety Study
This observational study will follow pediatric patients with eosinophilic esophagitis who are scheduled to begin topical steroid treatment, from the initiation of treatment longitudinally to determine the safety profile of the drug.
Eosinophilic Gastrointestinal Disorders Registry
The purpose of this study is to learn more about Eosinophilic Gastrointestinal Disorders (EGIDs). With this registry we hope to find out more about the symptoms that patients have during their treatment, the quality of life they have with the diagnosis, what the disease looks like throughout the different treatment methods, and if there is a connection between EGIDs and connective tissue disorders. The goal of this study is to be able to better understand EGIDs and use information gained from all the information collected on this study for more precise treatments in the future. We want to create a large collection of samples,...
Epidemiology and Management of Pediatric Anaphylaxis and Allergy in the Pediatric Emergency Department of Montpellier
Anaphylaxis is a severe life-threatening reaction following exposure to an antigen. Its incidence is progressively increasing in the general population over years, especially among children. The diagnosis can be difficult, and recommendations for follow up and prescription for an emergency kit are rarely provided after emergency visit. The Investigators will evaluate the management of pediatric anaphylaxis and clinical signs of allergy in the pediatric emergency department of Montpellier University Hospital
