The use of adjunctive therapies during oral immunotherapy: A focus on biologics.

Oral immunotherapy (OIT), thus far, is the most evaluated therapeutic approach for food allergy. However, OIT is not known to lead to a cure, and it carries a risk for allergic reactions. Adjunct therapies to OIT are currently being investigated to evaluate their effect on safety and outcome. Of these therapies, omalizumab is the most evaluated biologic. There is mounting evidence that omalizumab is effective in inducing rapid desensitization of OIT in both single-food and multiallergen OIT, while diminishing the rate of adverse reactions. Evaluation of other adjunct biologics, such as dupilumab and bacterial therapy, is underway.
