Omalizumab to Treat Eosinophilic Gastroenteritis
GastroenteritisThis study will evaluate the safety and usefulness of omalizumab (anti-IgE, Xolair) in reducing eosinophil counts and improving symptoms in patients with eosinophilic gastroenteritis (EG). EG is a disorder of unknown cause in which eosinophils, a type of white blood cell, are increased in the blood and gut tissue. Patients with EG have symptoms like stomach pain, bloating, and vomiting. About 50 percent of EG patients have food or environmental allergies, which may play a role in EG. Some patients with EG improve significantly on diets avoiding foods to which they are allergic. Immunoglobulin E (IgE) is an antibody that plays an important role in initiating allergic reactions. Omalizumab is a monoclonal antibody directed against IgE. The Food and Drug Administration approved omalizumab in 2003 for treating patients 12 years of age and older with allergic asthma. Patients between 12 and 76 years of age with eosinophilic gastroenteritis who have a blood eosinophil count of 500 or more and who have a food allergy or allergy to an inhaled allergen may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood and urine tests. Participants undergo the following procedures: Leukapheresis. This procedure is done to collect quantities of white blood cells to study the effects of omalizumab on eosinophils and other immune substances. Blood flows from a needle placed in an arm vein through a catheter (plastic tube) into a machine that separates the blood into its components by centrifugation (spinning). Some of the white cells are removed and the rest of the blood (red cells, plasma and platelets) is returned to the body through a needle in the other arm. Skin testing. Participants are tested for allergies to specific substances. A small amount of various allergens (substances that cause allergies) are placed on the subject's arm. The skin is pricked at the sites of the allergens and the skin reaction after several minutes is observed. Upper and lower endoscopy. One or both of these procedures is done, depending on the part of the gastrointestinal tract that is involved, to examine the tract. If both procedures are done, they are performed at the same time. For the upper endoscopy, the subject's throat is sprayed with a numbing medicine and a long, flexible tube is passed through the esophagus, stomach and small intestine. For the lower endoscopy, the tube is passed through the rectum into t...

Efficacy, Safety, and Pharmacokinetics of APT-1011 in Subjects With Eosinophilic Esophagitis (EoE)...
Eosinophilic EsophagitisEosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus, characterized by eosinophilic infiltration and gastrointestinal symptoms. Swallowed, topically acting corticosteroids, such as fluticasone, appear to be effective in resolving acute clinical and pathological features of EoE. APT-1011 is an orally disintegrating tablet (ODT) formulation of fluticasone propionate. This study is designed to compare the efficacy and safety of APT-1011 with placebo in adults with EoE for an initial 12-week treatment period, followed by an additional 40-week maintenance treatment phase. Histologic response, pharmacokinetics, and dysphagia will be assessed.

Eosinophilic GastritisEosinophilic DuodenitisThis is a Phase 3, multi-center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of lirentelimab (AK002), given monthly for 6 doses, in patients with moderately to severely active Eosinophilic Gastritis and/or Eosinophilic Duodenitis (formerly referred to as Eosinophilic Gastroenteritis) who have an inadequate response with, lost response to, or were intolerant to standard therapies
A Study to Assess the Safety and Efficacy of Oral Etrasimod in Adult Participants With Eosinophilic...
Eosinophilic EsophagitisThe purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for active eosinophilic esophagitis (EoE) in adult participants.
SAD, MAD and Food Effect Evaluation of Safety, Tolerability, and PK of AQ280 in Healthy Subjects...
Eosinophilic Esophagitis (EoE)The principal aim of this study is to obtain safety and tolerability data when AQ280 is administered orally as single and multiple doses to healthy subjects. This information, together with the pharmacokinetic (PK) data, will help establish the doses and dosing regimen suitable for future studies in patients.

Eosinophilic EsophagitisThe purpose of this study is to asses the efficacy, safety and tolerability of repeat doses of IRL201104 in Adult Participants with Active Eosinophilic Esophagitis (EoE)
An Extension Study to Evaluate Maintenance of Efficacy and Long-term Treatment Effect of Oral Budesonide...
Eosinophilic Esophagitis (EoE)This is a multicenter, double- blind extension study of Oral Budesonide Suspension (OBS) in adults and adolescents (11 to 55 years of age, inclusive) with Eosinophilic Esophagitis (EoE) who have completed participation in the SHP621-301 induction study (NCT02605837). The primary objective is to evaluate the maintenance of efficacy of OBS over 36 weeks. Maintenance of efficacy will be measured by the peak eosinophilic count and Dysphagia Symptom Questionnaire (DSQ) score.
Dietetic Versus Topical Steroids for Pediatric Eosinophilic Esophagitis
Eosinophilic EsophagitisTherapeutic strategies for eosinophilic esophagitis (EoE) actually include: 1) allergen avoidance through dietary modifications, and 2) pharmacologic antiinflammatory therapy. Medical treatment is mainly based on topical administration of corticosteroids by swallowing fluticasone propionate or budesonide spray. Dietetic treatment with highest efficacy is elemental diet, consisting in exclusive feeding with amino-acid based formulas, often administered trough SNG. Alternative choices of acceptable efficacy are empirical six-foods elimination diet (cow's milk, egg, soy, wheat, peanuts, fish) and targeted elimination diet based on the results of allergy tests. Most of the paediatric patients with EE respond to elemental or targeted elimination diets, and therefore such authors recommend elimination diets to be considered the treatment of choice in children. However, elimination diets can often be complex to follow and may be associated with poor adherence owing to the low palatability of a highly restricted diet. In non-compliant patients, especially in adolescents and young adults, it may be more practical to proceed first with corticosteroid treatment. In the case of partial response to elimination diets or corticosteroids, a combination of both treatment mod. However, there has been limited testing of these regimens in randomized controlled trials, while most of available literature is based on case series. The aim of this study was to compare the efficacy of six-foods elimination diet, swallowed fluticasone, swallowed budesonide and oral viscous budesonide (OVB) in pediatric patients with active EoE. The investigators assessed the effects of randomly assigned treatment on clinical and endoscopic/histologic severity as primary and secondary outcomes, respectively. The investigators describe clinical, allergological, endoscopic and histological features, and pH study results, of our pediatric population.
