Molecular Basis of Food Allergy

Study Purpose

The Study examines the molecular basis of food allergy. It explores the interaction between T cells, InKT cells and cytokines in the development of food allergy. The study also explores these factors in development of tolerance "outgrowing" food allergy. It will also explore the genetic factors that lead to the development of food allergy. The study examines all type of food allergy including IgE mediated reactions, Eosinophilic Esophagitis and Food Protein Induced Enterocolitis

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

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.

Eligible Ages 1 Month - 65 Years
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria for Study Group: 1. Males or females age 1 month to 65 years. 2. Diagnosis of Food Allergy. Food Allergy can be either IgE or non-IgE mediated food allergy including Eosinophilic Esophagitis and Food Protein Induced Enterocolitis. Inclusion Criteria for Control group: 1. Age and sex matched patients without food allergies. 2. Sibling and parents of patients with food allergies. Inclusion Criteria for Control group with atopy: 1. Age and sex matched patients without food allergies. 2. Sibling and parents of patients with food allergies. 3. Patients with atopy. Exclusion Criteria. 1. Underlying disease or medical problem that is judged to serious or risky to allow 3 ml/kg of blood to be drawn from a vein (such as serious anemia, cancer, poor vein abscess, serious infections). 2. Subjects that do not meet the enrollment criteria may not be enrolled. Any violations of these criteria will be reported in accordance with Institutional Review Board (IRB) policies and procedures study procedures.

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.


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.

Food Allergy, Eosinophilic Esophagitis
Additional Details

Food Allergy (FA) is a common pediatric atopic disease. Characteristically children affected by FA become sensitized to food in the first few months of life and spontaneously outgrow the disease by 5-6 years of age in about 80% of cases. At the present time, diagnosis of FA is made by a combination of history, skin testing and food challenge. The pathogenic mechanisms leading to food sensitization and subsequent spontaneous tolerance development are not understood.
