Food allergy yardstick: Where does omalizumab fit?

ABSTRACT

Food allergy management has greatly evolved in the last several years, moving from passive approaches, such as strict food allergen avoidance, to more active treatments, including regulatory approval of the first specifically indicated immunotherapy product (for peanut) in 2020. In 2024, a second therapy, omalizumab, received regulatory approval for the treatment of 1 or more IgE-mediated food allergies, providing clinicians with multiple treatment options to offer patients and families. With this expanded armamentarium of food allergy treatment options, the practicing clinician requires detailed knowledge of benefits and risks of omalizumab, how omalizumab fits into the management landscape, and how to use shared decision-making to optimize therapy. This yardstick aims to provide the clinician with a review of data leading to omalizumab's food allergy indication and an evidence-based expert opinion approach regarding on how best to use this and other therapies available to optimize patient management.
