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.

Addition of a single food lead to exacerbation of esophageal eosinophilia (increase of greater than 15 eos/hpf) or. 2.

History of either milk, egg, soy or wheat induced EoE based on introduction of the food and symptoms in the last 12 months. 4. Weight > 10 kg. 5. Ability to remain on stable dose of Proton Pump Inhibitor (PPI) therapy throughout the study. 6. Girls > 11 years of age must have a negative urine/serum pregnancy test. 7. Parental/guardian permission (informed consent) and if appropriate, child assent.
Exclusion Criteria:1. Tracheo-esophageal fistulas, inflammatory bowel disease, Barrett's disease, or other significant inflammatory disease of the gastrointestinal tract. 2. Biopsy evidence of eosinophilic infiltration in any other organ system. 3. History of significant esophageal procedures e.g. sclerotherapy or esophagectomy. 4. Systemic immunosuppressant usage in prior 3 months. 5. Narrow caliber esophagus defined as the inability to pass a 9.5 mm endoscopy into the esophagus. 6. IgE mediated reaction to food (milk, egg, soy or wheat) being introduced in the last 12 months. 7. Therapy with biologic molecule (e.g. omalizumab, infliximab) in prior 12 months. 8. Any factors that may pose a significant risk for undergoing anesthesia/sedation. 9. Subjects undergoing any type of immunotherapy to any food (oral immunotherapy, sublingual immunotherapy, specific oral tolerance induction) within 3 months prior to Visit 1. 10. Active IgE- mediated milk, egg, wheat or soy allergy based on skin test or history (if those foods are being introduced back into the diet). 11. Allergy or known hypersensitivity to the dupilumab. 12. Subjects (or parents of subjects) with obvious excessive anxiety and unlikely to cope with the conditions of an upper Endoscopy and biopsy. 13. Past or current disease(s), which in the opinion of the Investigator or the Sponsor, may affect the subject's participation in this study, including but not limited to active autoimmune disorders, immunodeficiency, malignancy, uncontrolled diseases (hypertension, psychiatric (especially anxiety), cardiac), or other disorders (e.g., liver, gastrointestinal, kidney, cardiovascular, pulmonary disease, or blood disorders). 14. Participation in another clinical intervention study in the three months prior to Visit 1. 15. Subjects unable to follow the protocol and the protocol requirements. 16. Subjects on any experimental drugs or treatments. 17. Subjects unable to read/understand English or follow the protocol and the protocol requirements.
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.

The disease, disorder, syndrome, illness, or injury that is being studied.
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.
