FARE Clinical Trial Finder
Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
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.
|Eligible Ages||18 Years - 70 Years|
- - Adults ages 18-70 years of age - Diagnosis of EoE, i.e. symptoms of esophageal dysfunction with histologic finding of 15 or more eosinophils per high power field on esophageal biopsy despite 8 weeks of high dose proton pump inhibitor therapy.
Exclusion criteria:- Clinical evidence of infectious process potentially contributing to dysphagia (e.g. candidiasis, CMV, herpes) - Other cause of dysphagia identified at endoscopy (e.g. reflux esophagitis, stricture, web, ring, achalasia, esophageal neoplasm) - Esophageal minimal diameter < 13 mm on structured barium esophagram - Inability to read due to: Blindness, cognitive dysfunction, or English language illiteracy - Pregnant women
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.
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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Dietary therapy has been shown to be successful in the treatment of adult and pediatric patients with eosinophilic esophagitis (EoE). Dietary studies were initially reported in children, but the results appear to be similar in adult patients. Elemental diets are successful in 70-95% of patients but are poorly tolerated. The six food elimination diet (SFED) involves the elimination of the six most common food allergens (i.e. milk, wheat, soy, eggs, nuts, and fish) for six weeks and has become the mainstay of dietary therapy in EoE. A six week SFED has demonstrated excellent efficacy and durability in both pediatric and adult EoE. However, compliance with the SFED for a total of six weeks can be challenging for patients. Previous studies have found the esophageal sponge to be an accurate technique of accessing esophageal eosinophilia in EoE . The sponge is swallowed as a 12 mm capsule on a string. The capsule rapidly dissolves upon entering the stomach and the sponge then expands and can be pulled out the mouth five minutes after ingestion. In previous studies, the procedure was very well tolerated and all patients preferred the sponge to endoscopy. Therefore the sponge is a well tolerated, inexpensive, very low risk procedure that would be an ideal option to replace EGD esophageal sampling in the evaluation of dietary treatment of EoE. Although initially described as a six week trial, it is possible that a shorter duration food elimination diet of 2 or 4 weeks would have equal efficacy. This would have important implications for patients as it would make the diet more tolerable.
