Biologics and Novel Therapies for Food Allergy

Abstract

Food allergy is a significant public health burden affecting around 10% of adults and 8% of children. Although the first peanut oral immunotherapy product received Food and Drug Administration approval in 2020, there is still an unmet need for more effective therapeutic options that minimize the risk of anaphylaxis, nutritional deficiencies, and patient's quality of life. Biologics are promising modalities, as they may improve compliance, target multiple food allergies, and treat other concomitant atopic diseases. Although omalizumab has been evaluated extensively, most biologics are more novel and have broader immunologic impact. Careful evaluation of their safety profile should therefore be conducted.
