About this trial
The goal of this interventional study is to evaluate whether skin barrier abnormalities occur in subjects with a food allergy, as determined by positive oral food challenge (OFC). The main question it aims to answer is whether these skin barrier abnormalities can be reversed by omalizumab.
If there is a comparison group: Researchers will compare non-food allergic participants (who do not receive omalizumab) to see if they experience skin barrier abnormalities.
All food allergic participants will receive 4 months of Omalizumab treatment as well as two Oral Food Challenges. Participants will all undergo skin barrier assessments.

Male or female, 1-55 years old at screening.

Participant must meet the following clinical FA criteria: Food sensitization to peanut, hen's egg, a tree nut, sesame seed, cow's milk, wheat, or soy, within 1 year of screening AND experience dose-limiting, IgE mediated symptoms at or before 444mg of food protein cumulatively during screening OFC to peanut, hen's egg, a tree nut, sesame seed, cow's milk, wheat, or soy.
Disqualifiers
Inability or unwillingness of a participant and/or parent/legal guardian to give written informed consent and/or assent or comply with the study protocol.
Clinically significant laboratory abnormalities at Screening.
Sensitivity or suspected/known allergy to any ingredients (including excipients) of the active OFC material (other than the study food), or drugs related to omalizumab (e.g., monoclonal antibodies, polyclonal gamma globulin).
