Feeding kids tiny bits of allergens may help them beat food allergies
NCT ID NCT05738798
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether giving very small, daily doses of foods like peanut butter or boiled egg to children under 30 months can help them outgrow their food allergies. 500 kids with proven allergies will receive oral immunotherapy for one year, then be checked for tolerance. The goal is to see if this approach is safe, effective, and cost-saving compared to natural allergy resolution.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oral immunotherapy with common foods like peanut butter or boiled egg
- What this could lead to
- If it works, this could offer a practical way to help young children safely outgrow common food allergies without needing lifelong avoidance.
- What could go wrong
- This is an early-stage study with no FDA-approved product; the therapy uses everyday foods, which may still trigger allergic reactions. Success depends on long-term tolerance, which is not guaranteed.

Inclusion Criteria: * An IgE-mediated food allergy to peanut, cashew, hazelnut, walnut, cow's milk and/or hen's egg as proven by sensitization to the specific allergen (sIgE \> 0.35kU/l) and a positive oral food challenge. * The fore-mentioned allergens are introduced into the diet of the child (the child is tolerant for the specific allergen(s)), or the child is diagnosed with a food allergy for the specific allergen(s). Exclusion Criteria: * (Suspected) eosinophilic oesophagitis * Uncontrolled asthma/ viral wheeze. * The inability of parents to follow instructions, recognize allergic reactions or administer emergency medication. * Participation in any other intervention study at the time of the OIT study, with the exception of studies on guided early introduction of highly allergenic foods.
