Brief 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

Detailed 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 Childrens 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 metabolomics cytokines and proteomics in 30 patients with a history of IgE-mediated reaction to 1 or more foods assessed by sensitization food extracts using skin prick tests serum IgE to specific foods andor relevant component proteins and an IgE-mediated clinical reaction to a food on OFC
2 Confirm the diagnosis of IgE-mediated FA in all patients with a positive OFC
3 Treat all 30 patients with omalizumab for 4 months
4 Repeat OFC after 4 months of omalizumab therapy
5 To analyze TEWL STS Lipidomics metabolomics proteomics and cytokines in all 30 patients who were treated with omalizumab and completed the end of study OFC
Sample size will be 30 completed subjects Enrollment will occur over the course of 16 months with 2-4 participants enrolling each month Up to ten healthy control subjects will also be enrolled for skin tape strip analysis and TEWL as a comparator group to the FA group
All participants will have an initial screening visit where their clinical history of having an IgE-mediated reaction to specified foods will be elucidated along with review of relevant skin prick test SPT food-specific IgE values and Total IgE If these values were not obtained within the last 12 months SPT sIgE andor Total IgE will be performed at screening All food-allergic participants will undergo an open Screening OFC to one of their food allergens For continuation in the study the participant must experience dose-limiting symptoms consistent with an IgE-mediated reaction at or before 444mg of food protein cumulatively If they have a negative OFC additional screening OFCs may be performed to any eligible food STS and TEWL measurements will be performed prior to the first dose as well as before the second and third doses Ifwhen the participant has dose-limiting symptoms STS and TEWL will be stopped immediately
All food-allergic participants will receive omalizumab for 4 months All injections will be administered by a research nurse on the clinical research unit At the midway point of the study 2 months after the first omalizumab injection the participant will have STS and TEWL measurements performed
After 4 months of omalizumab administration an end of study OFC will be performed to the same food that was positive at the screening OFC to assess treatment effect along with analysis of the STS and TEWL
