Peanut Reactivity Reduced by Oral Tolerance in an Anti-IgE Clinical Trial

Summary

The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.
