NCT01867671

Brief Summary

This is a randomized, double-blind, placebo-controlled, multi-center study comparing peanut oral immunotherapy (OIT) to placebo in the induction of tolerance and desensitization in peanut-allergic children. Eligible participants with peanut allergy will be randomly assigned to receive either peanut OIT or placebo for 134 weeks followed by peanut avoidance for 26 weeks.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants Desensitized to Peanut Protein After 134 Weeks of Oral Immunotherapy (OIT)

    Definition of desensitized to peanut: A participant who passed the blinded (masked) oral food challenge (OFC) to10 grams of peanut flour (=5 grams of peanut protein) without significant symptoms.\* \*Significant symptoms include hives, wheezing, vomiting, or laryngeal edema.

    Week 134

Secondary Outcomes (4)

  • Percentage of Tolerant Participants at Week 160

    Week 160

  • Count of Participants With Transient Desensitization

    Week 134, Week 160

  • Highest Tolerated Cumulative Dose

    Initial Dose Escalation through Week 160 (Tolerance Assessment)

Study Arms (2)

Peanut Oral Immune Therapy (OIT)

EXPERIMENTAL

Peanut OIT for 134 weeks followed by peanut avoidance for 26 weeks.

Biological: Peanut Oral Immunotherapy - Liquid ExtractBiological: Peanut Oral Immunotherapy - Peanut Flour

Peanut Placebo

PLACEBO COMPARATOR

Peanut placebo for 134 weeks followed by peanut avoidance for 26 weeks. The placebo extract will be derived from oat flour source material.

Biological: Placebo for Peanut Oral Immunotherapy - Liquid Extract formBiological: Placebo for Peanut Oral Immunotherapy - Peanut Flour

Interventions

Used during initial dose escalation for doses 0.1 to 0.8 mg.

Peanut Oral Immune Therapy (OIT)

Similar in appearance, texture, and taste to peanut liquid extract.

Peanut Placebo

This will be used for the remainder of dose escalation, build-up, and maintenance.

Peanut Oral Immune Therapy (OIT)

Similar in appearance, texture, and taste to peanut flour.

Peanut Placebo

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Wheal ≥ 3mm on skin prick test to peanut extract compared to a negative control;
  • A clinical reaction at or below ingestion of 1 g peanut flour (500 mg peanut protein) during screening OFC;
  • Written informed consent from parent/guardian.

You may not qualify if:

  • History of severe anaphylaxis with hypotension to peanut;
  • Documented clinical history of allergy to oat;
  • Suspected allergy to oat and a wheal ≥7mm on skin prick test to oat extract compared to a negative control;
  • Chronic disease other than asthma, atopic dermatitis, rhinitis requiring therapy; e.g., heart disease or diabetes;
  • Active eosinophilic gastrointestinal disease in the past 2 years;
  • Participation in any interventional study for the treatment of food allergy in the 6 months prior to visit -1;

  • Severe asthma, as indicated by repeated hospitalizations or hospital emergency department visits;
  • Moderate asthma defined according to National Asthma Education and Prevention Program Expert;
  • Panel that requires more than fluticasone 440 mcg or its equivalent daily for adequate control;
  • Inability to discontinue antihistamines for skin testing, OFC and the initial dose escalation;
  • Use of omalizumab or other non-traditional forms of allergen immunotherapy (e.g., oral or sublingual) in the 12 months prior to visit -1;
  • Any systemic therapy which in the judgment of the investigator could be immunomodulatory (e.g. rituximab) in the 12 months prior to visit -1, systemic corticosteroid therapy of up to a total of three weeks is allowed;
  • Use of any investigational drug in 90 days prior to visit -1;
  • Plan to use any investigational drug during the study period;
