Effect of Omalizumab in the Skin of Food Allergy Patients
National Jewish Health
Summary
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.
Description
This is a phase IV open-label interventional pilot study of 30 patients enrolled at National Jewish Health to examine skin barrier function and response to OFC in patients with FA before and after 4 months of treatment with omalizumab. If enrollment is insufficient at National Jewish, Children's Hospital Colorado or another similarly qualified site will be used as a back-up site. Efficacy assessment will be assessed by the ability of Omalizumab to reduce clinical response to OFC. The safety of omalizumab will be concomitantly recorded. Specifically, we will: 1. Examine TEWL, STS lipidomics, m…
