Multi Immunotherapy to Test Tolerance and Xolair

Completed · Phase 2 · Has a placebo group

Conditions studied: Food Allergy

In brief

This is a phase 2 randomized, double-blind, placebo controlled study which will be conducted at multiple centers in the U.S. All subjects will receive oral immunotherapy for their specific food allergies (limited to 5 of those food allergens in Investigational New Drug (IND) 14831). All subjects will receive Omalizumab for 16 weeks. The subject's allergens will be introduced in a rush desensitization day at week 8. Subjects will return to clinic to escalate the dose of their allergens until 2,000mg protein of each allergen is reached Subjects will return to clinic for a DBPCFC to each allergen at week 30. If subjects are nonreactive to 2 or more allergens during their DBPCFC at week 30 they will be randomized to one of three double blinded arms: Arm A- continue with current dose (2000 mg each food allergen protein), Arm B-300 mg of each food allergen protein, Arm C-placebo (avoiding food allergen protein), their current dose. All subjects will return to clinic for a DBPCFC to each allergen at week 36. The final challenge of week 36 will be the final end of study visit. Safety is a paramount concern in the study design and will be monitored carefully throughout the study. Study subjects and their parents/guardians will receive extensive education on food allergy reactions and medication use.

You may not qualify if…

• Inability or unwillingness of a participant/parent/guardian to give written informed consent or comply with study protocol
• History of cardiovascular disease
• History of other chronic disease (other than asthma, atopic dermatitis, or rhinitis) requiring therapy (e.g., heart disease, diabetes) that, in the opinion of the Principal Investigator, would represent a risk to the participant's health or safety in this study or the participant's ability to comply with the study protocol
• A total IgE at screening of >2,000 kU/L

• A history of severe anaphylaxis (defined as requiring intubation or admission to an ICU) to food allergens that will be used in this study
• Unstable angina, significant arrhythmia, uncontrolled hypertension, current smokers, chronic sinusitis, or other chronic or immunological diseases that, in the judgment of the investigator, might interfere with the evaluation or administration of the test drug or pose additional risk to the participant.
• Current use of oral, intramuscular, or intravenous corticosteroids, tricyclic antidepressants, or betablockers (oral or topical)
• Routine use of medication that could induce adverse gastrointestinal reactions during the study
• Refusing to sign the Epinephrine autoinjector Training Form
• Pregnant or breast feeding women
• A history of oat allergy (since oat is the placebo agent in the DBPCFC), or an objective reaction to the screening DBPCFC to oat
• Unwilling to avoid all food allergen-containing items except those given as part of the Oral Immunotherapy as well as any other food allergens you are allergic to that are not included in the 10 foods listed in the study
