Proton Pump Inhibitor (PPI) Response in Eosinophilic Esophagitis Assessed by Transnasal Endoscopy (TNE)

Study Purpose

This study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE). Upon study enrollment, the participant will begin a proton pump inhibitor (PPI), Omeprazole 20mg twice daily. After taking Omeprazole for four weeks, the participant will have a Transnasal Endoscopy, and biopsies will be taken to determine the histological change. If the biopsies are abnormal, the participant continues Omeprazole and will undergo another endoscopy at eight weeks. The study aims to determine the percentage of children with Eosinophilic Esophagitis who improve with PPI use and to determine the length of time and effectiveness of PPI therapy in the management of EoE. The investigators hypothesize that following the initiation of PPI for treatment of Eosinophilic Esophagitis, biopsies obtained will show decreasing eosinophil counts at four weeks, which is sooner than the previously reported eight week period.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04149470
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Eosinophilic Esophagitis
Additional Details

This study aims to learn more about the subset of children with Eosinophilic Esophagitis (EoE) who are on treatment with a proton pump inhibitor (PPI). EoE is an increasingly common allergic condition of the esophagus for which we have limited treatment options. This study will be helpful in evaluating the minimal time frame required for histological improvement with the use of high dose PPI. The study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE) and are recommended by their physician to begin PPI treatment with Omperazole 20 mg twice daily. After taking Omeprazole for four weeks, the participant will undergo an unsedated Transnasal Endoscopy (TNE) in the outpatient clinic at Children's Hospital Colorado. TNE is a test in which the doctor inserts a skinny bendable tube with a camera through the nose to look directly into the esophagus (the tube connecting the mouth to the stomach when you swallow) and is an alternative method to assess esophageal mucosa without requiring general anesthesia. Biopsies will be collected during the TNE to determine if there is histological change. If the biopsies are normal, the participant will complete the study. If biopsies are abnormal, and EoE is still active, the participant will continue the Omperazole and undergo the standard of care endoscopy at eight weeks. The participant will chose the type of endoscopy- unsedated TNE or esophagogastroduodenoscopy (EGD) under anesthesia. Participants will also complete surveys during study enrollment about medication compliance, Eosinophilic Esophagitis symptoms, anxiety, TNE experience, and undergo a physical exam. The investigators hypothesize that following the initiation of PPI for treatment of Eosinophilic Esophagitis, biopsies obtained will show decreasing eosinophil counts at four weeks, which is sooner than the previously reported eight week period. Results from this study will be generalizable to the pediatric EoE population and the knowledge gained will provide key preliminary data to support clinical recommendations for pediatric EoE patients.
