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.

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.

|Food Allergy, Egg Protein Allergy, Immune Tolerance|
Oral immunotherapy (OIT) is a therapeutic approach, where gradually increasing doses of a specific food allergen are administered orally. OIT can desensitize up to 80% of children with persistent food allergy, and in a subset lead to sustained immune tolerance. The immunologic mechanisms induced by OIT are still poorly understood. In this randomized cross-over study, 50 children with challenge-confirmed hen's egg (HE) allergy will be randomized (2:1) to receive either active HE OIT or continue on an avoidance diet for 6 months after which active OIT is started. The immunological changes induced by OIT will be compared to the patient's initial status and to that of the patients on an avoidance diet. Serum antibody and humoral mediator analyses as well as gene expression of blood mononuclear cell (PBMC) by genome-wide microarray assays will be studied. PBMCs will be stimulated with HE allergens and innate immunity agonists, and the differences in the expression profiles of messenger-RNAs as well as microRNAs will be studied. Single-cell sequencing and sorting of regulator T cells (Tregs) will be performed focusing on their transcriptomic responses and gene methylation. Finally, clinical data, transcriptomics and epigenetic changes will be combined and analyzed by advanced system biology methods. This study will provide better understanding of the effects and mechanisms of OIT and identify biomarkers for selection of patients benefitting from personalized OIT.
