Abstract
Multiple biologic agents are approved for the treatment of severe persistent asthma not controlled by inhaled corticosteroid/beta-agonist therapy. Appropriate phenotyping can aid in picking the right biologic for the right patient. Here is a unique case of a patient with severe asthma and respiratory arrest, with fraction of exhaled nitric oxide >300 ppb whose asthma became completely controlled with dupilumab.
