Participants will be randomized in a 2:1 ratio to receive either multi-OIT or standard management consisting of an elimination diet. The primary objective is to evaluate immunotherapy efficacy defined as achieving tolerance to a cumulative dose of 4444 mg of protein during an oral food challenge (OFC-2) for at least one allergen that elicited a reaction during baseline challenge (OFC-1), compared with the control group. Secondary outcomes include the proportion of participants tolerating multiple allergens at the target cumulative dose; the incidence, type, and severity of adverse events classified according to the World Allergy Organization (WAO) grading system; changes in immunological parameters, including allergen-specific IgE and IgG4 levels; changes in skin prick test responses; changes in the quality of life of patients and their families.",[116,117,118,119,120],"Food Allergies","Food Allergy in Children","Peanut Allergies","Tree Nut Allergies","Oral Immunotherapy for Food Allergy","NOT_YET_RECRUITING","2026-08-11",{"date":124,"type":125},"2026-08-13","ACTUAL",{"date":127,"type":110},"2026-09",{"date":129,"type":110},"2031-12",{"name":5,"class":6},4]
