Mucosal Immunotherapy for Peanut Allergy in Young Children
Determining the Efficacy and Value of Immunotherapy on the Likelihood of Peanut Tolerance: The DEVIL Study

Peanut allergy is known to cause severe anaphylactic reactions.The goal of this proposal is to produce a new treatment that would benefit young subjects who have recently been diagnosed with peanut allergy by lowering the risk of anaphylactic reactions (desensitization), and changing the peanut-specific immune response in subjects who have peanut allergy (tolerance).

Peanut allergy is known to cause severe anaphylactic reactions. Compared with other food allergies, it tends to be more persistent and its prevalence seems to be rising. Currently, there is no proven treatment other than strict avoidance. We are attempting to decrease the risk of anaphylaxis on accidental ingestion by desensitizing subjects to peanut using peanut mucosal immunotherapy (PMIT). We are also studying the effect of PMIT on the peanut-specific immune response to determine if tolerance to peanut protein will develop. Based on our preliminary work and recent studies supporting the importance of early oral exposure in tolerance induction, we propose that early treatment of peanut allergy with PMIT will be safe and effective. Children ages 9 to 36 months with peanut allergy will be randomized to receive high or low dose PMIT using peanut flour. Peanut-allergic subjects receiving no intervention will serve as controls. Subjects will undergo desensitization on the first day and then increase the doses gradually to a maintenance dose. Doses will be taken daily at home except for dose increases which will be done on the research unit. Subjects will undergo a double-blinded, placebo-controlled food challenge (DBPCFC) if challenge criteria are met. Subjects passing the first challenge will stop PMIT and repeat the DBPCFC to assess tolerance. Outcome variables of interest include response to oral food challenges (OFC), skin prick testing, peanut specific serum immunoglobin E (IgE), immunoglobin G (IgG), and immunoglobin G4 (IgG4) and stool immunoglobin A (IgA), T and B cell responses, quality of life, and adverse events. These longitudinal results will be compared between high and low dose PMIT groups and controls using appropriate statistical analysis.

Phase 1
Phase 2
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Food Hypersensitivity
  • Drug: Peanut and placebo flour
    Peanut flour mixed with placebo will be given in gradually increasing doses.
  • Drug: Peanut protein flour
    Peanut flour will be given in gradually increasing doses.
  • Experimental: Low dose peanut protein
    Subject will be randomized to receive a low dose of peanut protein mixed with a placebo protein.
    Intervention: Drug: Peanut and placebo flour
  • Experimental: High dose peanut protein
    Subject will be randomized to receive a high dose of peanut protein.
    Intervention: Drug: Peanut protein flour
  • No Intervention: Historical Control
    This group will be followed for the same amount of time as the active subjects, to observe the natural history of peanut allergy.
