詳細な説明
This is an interventional, open-label, multicenter, randomized clinical trial enrolling 39 children aged 1-12 years with confirmed allergy to at least two of the following allergens: peanut, cashew, walnut, hazelnut and almond.
Participants will be randomized in a 2:1 ratio to either the experimental group receiving multi-food oral immunotherapy (multi-OIT) or the control group receiving standard of care consisting of an elimination diet and rescue medications. Multi-OIT will be administered using a standardized mixture of peanut and tree nuts proteins, with a dose-escalation phase followed by a maintenance phase targeting 300 mg of protein per allergen per day. Treatment duration will be approximately 18 months.
All participants will undergo oral food challenges at baseline (OFC-1) and at the end of the study (OFC-2). The primary efficacy endpoint is defined as the proportion of participants achieving tolerance to a cumulative dose of 4444 mg of protein during OFC-2 for at least one allergen that elicited a reaction during OFC-1, compared with the control group. Safety will be monitored throughout the study based on adverse events recorded in symptom diaries and classified according to established grading systems.
Secondary outcomes include the proportion of participants tolerating multiple allergens at the target cumulative dose, the frequency 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), skin prick test responses and quality of life of patients and their families.
Participants in the control group will be offered the option to receive immunotherapy after completion of the study.

実験的:Multi-Food Oral Immunotherapy (Multi-OIT)
Participants will receive multi-food oral immunotherapy (multi-OIT) using a standardized mixture of peanut and tree nuts proteins (cashew, walnut, hazelnut, and almond).
Treatment includes a dose-escalation phase (1-300 mg protein per allergen) followed by a maintenance phase for 12 months (+/- 3 months) with a target daily dose of 300 mg of protein per allergen.
Dose increases will be performed under medical supervision, and daily dosing will be continued at home.
The total treatment duration is approximately 18 months.
