Dupixent® by Sanofi received FDA marketing authorization in October 2018 for use as an add-on maintenance therapy in patients aged 12 years and older with moderate-to-severe asthma, particularly those with an eosinophilic phenotype or other specific conditions. In May 2019, the European Commission granted approval for Dupixent® to serve as an add-on maintenance treatment in patients aged 12 years and older who have severe asthma with type 2 inflammation and are inadequately controlled by high-dose inhaled corticosteroids, in conjunction with another maintenance medicinal product.
