Natural History and Genetics of Food Allergy and Related Conditions
NCT02504853 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- About 15 million Americans have a food allergy. Because there are no cures or effective prevention or treatment for food allergies, researchers want to learn more about them. Objective: \- To learn more about the causes and effects of food allergy and related conditions. Eligibility: * People ages 2 99 who have food allergy and/or a related genetic or other condition * Their relatives * Healthy relatives and volunteers Design: * Participants will have at least 3 visits over 1 2 years, and then once a year for up to 12 years. Each may last a day or longer. * Participants will be screened with medical history, physical exam, and questionnaires. * Participants may have the following: * Blood tests * Allergy skin prick tests: Drops of allergens are placed on the back or arm. The skin is scratched under each drop. * Leukapheresis: blood is taken from a needle in one arm, passed through a machine, and returned through a needle in the other arm. * X-rays * Esophageal string test: One end of a string is taped to the cheek and the other end is packed into a capsule. When the capsule is swallowed, the string unwinds; it is left in for at least 1 hour. * EGD and colonoscopy: Biopsies are taken from the gastrointestinal system. * Tiny biopsies of skin * Photographs of the body * Collection of cells through: * Swab of nose, inside of cheek, or skin * Gentle skin scrape * Tape stripping: piece of tape is put on the skin and pulled off.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02504853
The ClinicalTrials.gov registry entry for NCT02504853 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,800 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Atopic Dermatitis appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02504853 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
