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||7 Years - 65 Years|
- - Participant must be able to understand and provide informed consent - Males and Females ≥7 years of age to 65 years of age - Have diagnosis of EoE - Have histologically confirmed active disease ≥15 eosinophils/hpf - Symptomatic (have experienced symptoms within the last one months prior to enrollment).
Exclusion Criteria:- Inability or unwillingness of a participant to give written informed consent or comply with study protocol - Secondary causes of eosinophilia - Pregnancy - Immunodeficiency states - Have participated in any investigative drug study within 6 weeks prior to study entry - Unable to complete study procedures including endoscopy - Luminal stricture identified <13mm which would prevent passage of the EST and prevent assessment of mucosal inflammation - Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study
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 disease, disorder, syndrome, illness, or injury that is being studied.
This is an adult and pediatric prospective, longitudinal study in which we will measure symptoms, QOL and inflammation at baseline and again at 2, 4 and 6 weeks after starting stand of care (SOC) four food elimination diet (FFED) (Aim 1). Newly or previously diagnosed patients with EoE with active disease who will be undergoing SOC FFED will be offered entry into the study by the PI's or their local co-investigators at each of their institutions. EoE patients who are in remission on SOC FFED from Aim 1 will be recruited to participate in this food reintroduction trial in Aim 2. Eligible subjects will undergo SOC sequential food reintroductions and during the food introduction, ESTs will be performed at 2 and 4 week intervals during a clinic visit. If inflammation is detected by the EST, this food will be eliminated from the diet for six weeks and a repeat EST will be administered at this time to assess inflammation. If inflammation has resolved based on EST results, food reintroduction will resume. If no inflammation is detected by the EST at the 4 week interval, a new food will be added. EST will be performed after each food reintroduction as outlined above. Based on known allergenic properties of these foods, the order of food reintroduction will be soy, eggs, wheat and milk.
Experimental: Four Food Elimination Diet (FFED)
There is one arm to the study. All participants meeting eligibility will be assigned to intervention / treatment with a previously defined four food elimination diet (FFED) (Aim 1). This is a longitudinal study in which outcome measures including symptoms, QOL and inflammation at baseline and at 2, 4 and 6 weeks after starting stand of care (SOC) FFED will be measured. Participants meeting eligibility for Aim 2 will have foods added back to the diet using a specified protocol.
Other: - Four Food Elimination Diet
Food allergens are thought to initiate eosinophilic inflammation and dietary elimination of trigger allergens is an effective treatment for EoE. Previous work demonstrates that in both children and adult EoE patients, the food antigens including cow's milk, wheat, egg, soy, peanut/tree nut and fish/shell fish, are the most common food triggers causing esophageal inflammation. Participants will be assigned to single arm treatment / intervention with a diet restricted of the four most common food allergens, milk, soy, wheat and egg, or a four food elimination diet (FFED). With the goal to optimize diet treatment, in Aim 2, eligible participants will undergo sequential food reintroductions based on protocol.
