Measure
Placebo
Xolair will be administered in week 0 through 16 of the study. Starting at week 8, food doses will be serially increased, per protocol, to up to 2000 milligrams per food. At week 30, the cohort will be randomized into 3 groups (placebo, low dose food, and high dose food). Participants will continue on this dose for 6 weeks. The oat placebo food, will be compared to high dose (2000 milligrams or low dose 300 milligrams food immunotherapy). At week 36 a food challenge will be performed to assess study endpoints. Omalizumab: Omalizumab is administered per product insert from weeks 0 -16 of the study. Food Flour Buildup: Food flours identified as allergic (based on food challenge), will be introduced at week 8. The food dose will be escalated every 2 weeks up to 2000 milligrams of each of the food flours. Subjects are required to reach 300 milligrams at week 16 to continue to week 30. Subjects must tolerate 2000 milligrams per food by week 28 in order to be randomized.
Low Dose Food
Xolair will be administered in week 0 through 16 of the study. Starting at week 8, food doses will be serially increased, per protocol, to up to 2000 milligrams per food. At week 30, the cohort will be randomized into 3 groups (placebo, low dose food, and high dose food). Participants will continue on this dose for 6 weeks. The oat placebo food, will be compared to high dose (2000 milligrams or low dose 300 milligrams food immunotherapy). At week 36 a food challenge will be performed to assess study endpoints.

Omalizumab: Omalizumab is administered per product insert from weeks 0 -16 of the study. Food Flour Buildup: Food flours identified as allergic (based on food challenge), will be introduced at week 8. The food dose will be escalated every 2 weeks up to 2000 milligrams of each of the food flours. Subjects are required to reach 300 milligrams at week 16 to continue to week 30. Subjects must tolerate 2000 milligrams per food by week 28 in order to be randomized.
