FDA Approves new indication for Xolair
The U.S. Food and Drug Administration (FDA) approved a new indication for Genentech/Novartis’ Xolair (omalizumab), an anti-immunoglobulin E (IgE) antibody. Xolair is now indicated for IgE-mediated food allergy in adult and pediatric patients 1 year of age and older for the reduction of allergic reactions (Type I). This includes anaphylaxis, that may occur with accidental exposure to one or more foods. Xolair is intended to be used in conjunction with food allergen avoidance.
Xolair was first approved in 2003 for moderate to severe persistent allergic asthma and has since been approved for perennial aeroallergen allergies, to treat chronic idiopathic urticaria, and as an add-on maintenance treatment for nasal polyps in adults with inadequate response to nasal corticosteroids. Xolair does not treat acute allergic food reactions and does not replace the use of epinephrine for such reactions. Patients taking Xolair for food allergies may need to continue to carry epinephrine for treating emergency allergic reactions.
Xolair is the first FDA-approved medication to reduce allergic reactions to more than one type of food after accidental exposure. Aimmune Therapeutics’ Palforzia (peanut [Arachis hypogaea] allergen powder-dnfp) is an oral immunotherapy product approved in patients 4–17 years of age for the mitigation of allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanut, but its use is restricted to peanut allergy. There are other agents in development for food allergies, including some for multiple food allergies.
