Asthma Biologics

The development of multiple targeted biologic therapies over the past two decades has revolutionized the management of asthma. Currently, there are 6 monoclonal antibodies that target specific inflammatory mediators involved in the pathophysiology of asthma, and together, they provide the opportunity for personalized treatment options beyond bronchodilators and inhaled or systemic glucocorticoids in severe and difficult-to-control cases of asthma. These agents are the anti-IgE antibody omalizumab, the anti-IL-5 antibodies mepolizumab and reslizumab, the IL-5 receptor alpha antagonist benralizumab, the IL-4 receptor alpha antagonist dupilumab, and the anti-thymic stromal lymphopoietin antibody tezepelumab.
