Eosinophilic Esophagitis Clinical Trial

Official title: Efficacy of Dupilumab on Facilitated Food Introduction in Eosinophilic Esophagitis

Status Active, not recruiting

Clinical Trial Summary

Eosinophilic Esophagitis (EoE) is a food driven non-immunoglobulin E (IgE) mediated disease involving eosinophils and type 2 inflammation. Current therapies include diet and the off label use of medications including proton pump inhibitors, topical steroids or biologics. Food elimination creates a decrease quality of life in many children. The goal of the study is to examine a T2 inhibitor (dupilumab) can allow successful reintroduction of allergic EoE foods into the diet. This is a single site study, enrolling subjects 6 to 25 years of age.

Clinical Trial Description

This study is an open label exploratory study to examine if patients controlled with dupilumab can successful introduce EoE trigger foods back into their diet.

This is a single site study, enrolling subjects 6 to 25 years of age. In the initial 12 week period, patients will be start on dupilumab on the doses used in the phase 3 trials to control disease. If disease is controlled based on histologic and symptom control at week 12 endoscopy, patients will be start on EoE trigger food. The trigger foods will be based on both a combination of history and histology results. The food will have trigger EoE by histology in the last 2 years and symptoms in the last year when reintroduced into the diet. The study will focus on the the four most common foods that trigger EoE: milk, egg, wheat and soy. For the initial food introduction, the subjects will add one serving size of the food daily for 12 weeks. After 12 weeks, the subjects will have a 2nd endoscopy if the 2nd endoscopy is normal, the subjects will increase the trigger food to 2 serving sizes a day or add an additional trigger food. A 3rd endoscopy will be done if the patients increases the food amount or adds a new food at week 36 (12 weeks after adding the new food). If the subject does not increase or add new foods at week 24, the 3rd endoscopy will not be obtained. All subjects will have end of study endoscopy at week 48.

If the subjects have abnormal endoscopy or increase in symptoms, the amount food will be reduced by 50% and repeat endoscopy will be obtained at the same time schedule-12 weeks later. ;
