Brief 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.

Eligibility Criteria
You may qualify if:
- Moderate to severe peanut allergy-sensitive subjects between the ages of 7 to 25 years old.
- Sensitivity to peanut allergen will be documented by a positive skin prick test result (6 mm diameter wheal or greater)
- ImmunoCAP IgE level to peanut \> 10 kU/L.
- Sensitivity to peanut allergen based on a double-blind placebo-controlled oral food challenge (DBPCFC) at maximum of cumulative 175 mg of peanut protein dose.
You may not qualify if:
- Subjects with a total IgE at screening of \< 50 kU/L \> 2,000 kU/L.
- Positive reaction to the placebo on DBPCFC.
- Previous reaction to omalizumab.
- Subjects having a history of severe anaphylaxis to peanut requiring intubation or admission to an ICU, frequent allergic or non-allergic urticaria, or history consistent with poorly controlled persistent asthma, or gastrointestinal or gastroesophageal disease.
