Purpose
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.

| Official Title: | Phase 2 Study of Omalizumab in Oral Peanut Desensitization |
- The ability of omalizumab-treated subjects to successfully complete the build-up phase of peanut, and tolerate daily 4,000 mg doses of peanut flour after discontinuing omalizumab. [ Time Frame: 14 wks after the start of oral peanut desensitization (wk 26 of study). ] [ Designated as safety issue: Yes ]
- The ability of subjects to tolerate an oral dose of 4,000 mg peanut. [ Time Frame: 8 wks after the start of oral peanut desensitization (study wk 20). ] [ Designated as safety issue: Yes ]

Detailed Description:
36 subjects will receive Xolair, and 8 subjects will receive placebo. The study will occur at 4 sites: Boston Children's Hospital, Children's Hospital of Philadelphia, Stanford University and Lurie Children's Hospital.
Patients will be pre-treated with Xolair or placebo before rapid oral peanut desensitization. Patients will continue to receive Xolair during the 8 subsequent weeks of desensitization, receiving their final dose of Xolair one week after reaching the highest tolerated dose of peanut.
