Airway eosinophils are considered to play an important role in the pathogenesis of asthma. Interleukin-5 is believed to be a key cytokine for the development, proliferation and activation of eosinophils. Benralizumab is an anti-interleukin-5 receptor α monoclonal antibody that depletes blood and airway eosinophils. We conducted a phase 2a study in South Korea and Japan to evaluate the effect of benralizumab in an East Asian population. The primary objective was to evaluate the effect of benralizumab in adults with uncontrolled eosinophilic asthma with 2-6 incidences of exacerbations in the past year using a medium/high dose of inhaled corticosteroids and long-acting β2-agonists.
