A Study to Assess Subcutaneous AK002 in Eosinophilic Gastritis and/or Eosinophilic Duodenitis

Eosinophilic GastritisEosinophilic Duodenitis

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, tolerability, and pharmacodynamic effect of subcutaneous lirentelimab (AK002), given monthly for 6 doses, in subjects with moderate to severe Eosinophilic Gastritis and/or Eosinophilic Duodenitis who have an inadequate response with, lost response to, or were intolerant to standard therapies.

Allergy Immunotherapy in the Management of Eosinophilic Esophagitis

Eosinophilic Esophagitis

Eosinophilic esophagitis (EoE) is a disease that has increased in incidence over the past decade that affects males predominantly, and in adults, is characterized by heartburn, dysphagia, strictures and food impactions. These symptoms may require emergent endoscopic removal of foods and esophageal dilations due to remodeling causing significant impairment in quality of life. Treatment options are limited and often not well tolerated or effective. There is poor understanding of the natural history and long term prognosis. It has been associated with allergic sensitization; a high percentage of affected individuals having associated atopy and current literature demonstrates a seasonal distribution of incidence and severity of symptoms. Allergy immunotherapy (AIT) is a well established and effective treatment for allergic rhinitis and asthma which can induce tolerance to environmental allergens. Given the efficacy of AIT and the association of aeroallergen sensitization and even seasonal variation of EoE symptoms, we hypothesized that AIT may be a treatment option for patients with EoE.

The Frequency of Eosinophilic Esophagitis in Patients With Heartburn That is Refractory to Proton...

Gastroesophageal Reflux DiseaseEosinophilic Esophagitis

Background: Up to 40% of patients who are treated with PPIs for symptoms that are thought to be due to GERD experience only incomplete relief of their symptoms. Those patients are deemed "PPI failures." Esophageal pH monitoring studies have shown that PPI failure rarely is due to persistent acid reflux. Recently, heartburn that is refractory to treatment with PPIs has been described in patients with eosinophilic esophagitis, a disorder of unknown etiology in which eosinophils infiltrate the squamous epithelium of the esophagus, where they cause symptoms and tissue injury. Presently, it is not clear how often eosinophilic esophagitis underlies PPI failure for patients with GERD symptoms. Purpose: To estimate the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. Methods: Patients referred to the Division of Gastroenterology at the Dallas VA Medical Center for the evaluation of heartburn that is refractory to PPI therapy will be invited to participate in the study. Patients who provide informed consent will have a medical history taken. Women of child bearing potential will have a pregnancy test. The patients' current PPI therapy will be discontinued, and patients will be treated with lansoprazole 30 mg BID for one week. The patient will return to the clinic one week later. Patients who feel that their heartburn has not improved by more than 50% from baseline will have an endoscopic evaluation. During the endoscopic examination, biopsy specimens will be taken as follows: A. Two specimens from the proximal esophagus at 20 cm from the incisor teeth. B. Two specimens from the mid-esophagus at 28 cm from the incisor teeth. C. Two specimens from the distal esophagus, 3 cm above the squamo-columnar junction. D. Two specimens from the distal esophagus, 1 cm above the squamo-columnar junction. E. Two specimens from the second portion of the duodenum (to see if the eosinophilia is confined to the esophagus, or part of a more extensive eosinophilic gastroenteritis). A diagnosis of eosinophilic esophagitis will be made if there is at least one high-power field with >25 eosinophils, or two or more high-power fields with >15 eosinophils. Potential Benefits: This study will provide an estimate on the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. This has substantial potential importance for patient management.

San Raffaele EoE Biobank

Eosinophilic Esophagitis

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.

A Randomized Double Blind Placebo Controlled Study of the Effect of Swallowed Beclomethasone Dipropionate...

Eosinophilic Esophagitis

The investigators hypothesize that swallowed beclomethasone leads not only to improvement of symptoms and decreased number of eosinophils in esophageal mucosa, but also to a decrease in other markers of tissue inflammation like mast cells, CD4+ T lymphocytes, IL4, IL-5, IL13, GM-CSF and TGF-beta as well as serum ultra-sensitive C-Reactive Protein (CRP). The investigators aim to characterize the response of esophageal inflammation to swallowed topical glucocorticoids, and identify biomarkers to assess response to treatment. This research will elucidate the effect of treatment with beclomethasone on various inflammatory markers in EoE, which is currently not well-understood. This work will explore the pathophysiology of EoE, and has the potential to find a non-invasive biomarker such as high-sensitivity CRP that can be used to monitor the response to treatment.

Cytosponge and Dietary Therapy in EoE

Eosinophilic Esophagitis

This study is being done to see if the investigators can use only the cytosponge ( A 10 minute, in office procedure that does not require sedation) to replace the 6-10 endoscopies routinely perform during dietary restriction and food reintroduction in EoE?

Pilot Study of Esocheck in Eosinophilic Esophagitis

Eosinophilic EsophagitisDiagnoses Disease

Eosinophilic esophagitis (EoE) is a prevalent chronic inflammatory condition of the esophagus characterized by esophageal eosinophilia that can lead to inflammation and stricture formation. To assess remission, esophagogastroduodenoscopies (EGD) with biopsies are performed. This can lead to multiple EGDs, which are invasive and costly procedures. EsoCheck is a promising noninvasive device. It is an encapsulated balloon that can be easily swallowed and collect cells from the distal esophagus. The primary aim of this study is to determine the feasibility and safety of EsoCheck compared with standard endoscopy and biopsies in the assessment of EoE. This will be a prospective cross-sectional study of adult patients (greater than or equal to 22 years of age) at the University of Pennsylvania with a diagnosis of EoE scheduled for a clinically indicated upper endoscopy.
