New study aims to unlock secrets of food allergy tolerance in kids

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: NAT-cohort: * Cow´s Milk and/or Hen´s Egg allergic patients 4 to 10 years old * sIgE levels to milk OR egg extracts between 0.35 to 35kUA/L * Positive entry Open food challenge with milk/egg with oFASS5 classification ≥2 with a maximum cumulative dose of up to 4193.7 mg of milk protein or 3110.8 mg of egg white protein * Having a mild to moderate food allergy severity per the Definition of Food Allergy Severity (DEFASE) score (\<13 points) * Having signed the informed consent OIT-cohort: * Patients in the compITO study (NCT06976775) who are undergoing OIT and have achieved full desensitization to the food by month 7 of the study (end of study) * Patients in the compITO study who are undergoing OIT and have achieved partial desensitization (tolerating a dose lower than the total dose, and a minimum of 3 doses above the entry challenge threshold) to the food by month 7 of the study (end of study) * Having signed the informed consent Exclusion Criteria: NAT-cohort: * Positive reaction in the entry open oral food challenge with a baseline Eliciting Dose (ED) 20 below the target ED20 for food.
