Omalizumab
Omalizumab, sold under the brand name Xolair among others, is an injectable medication to treat severe persistent allergic forms of asthma, nasal polyps, urticaria (hives), and immunoglobulin E-mediated food allergy.
Omalizumab is a recombinant DNA-derived humanized IgG1 monoclonal antibody which specifically binds to free human immunoglobulin E (IgE) in the blood and interstitial fluid and to the membrane-bound form of IgE (mIgE) on the surface of mIgE-expressing B lymphocytes. Its primary adverse effect is anaphylaxis.
In 1987, Tanox filed its first patent application on the anti-IgE drug candidate. Omalizumab was approved for medical use in the United States in June 2003, and authorized in the European Union in October 2005.
In the United States, omalizumab is indicated to treat moderate to severe persistent asthma; chronic rhinosinusitis with nasal polyps; immunoglobulin E (IgE)-mediated food allergy; and chronic spontaneous urticaria.
In the European Union, omalizumab is indicated to treat allergic asthma, chronic (long-term) spontaneous urticaria (itchy rash), and severe chronic rhinosinusitis with nasal polyps.
In Australia, omalizumab is indicated to treat allergic asthma and chronic spontaneous urticaria.
Omalizumab is used to treat people with severe, persistent allergic asthma that is not controlled with oral or injectable corticosteroids. Those patients have already failed step I to step IV treatments and are in step V of treatment. Such a treatment scheme is consistent with the widely adopted guidelines for the management and prevention of asthma, issued by Global Initiative of Asthma (GINA), which was a medical guidelines organization launched in 1993 in collaboration with the National Heart, Lung, and Blood Institute, National Institutes of Health, US, and the World Health Organization. A 2014 Cochrane review found that omalizumab was effective in reducing exacerbations and hospitalisations related to asthma when used as an adjunct to steroids.
Omalizumab is indicated for chronic spontaneous urticaria in adults and adolescents (>12 years old) poorly responsive to H1-antihistamine therapy. When administered subcutaneously once every four weeks, omalizumab has been shown to significantly decrease itch severity and hive count.
