Efficacy and Safety of Dupilumab in Glucocorticoid-Dependent Severe Asthma
BACKGROUND: Dupilumab is a fully human anti-interleukin-4 receptor α monoclonal antibody that blocks both interleukin-4 and interleukin-13 signaling. Its effectiveness in reducing oral glucocorticoid use in patients with severe asthma while maintaining asthma control is unknown. METHODS: ) before bronchodilator use were also assessed. RESULTS: that was 0.22 liters (95% CI, 0.09 to 0.34) higher. Injection-site reactions were more common with dupilumab than with placebo (9% vs. 4%). Transient blood eosinophilia was observed in more patients in the dupilumab group than in the placebo group (14% vs. 1%). CONCLUSIONS: . Transient eosinophilia was observed in approximately 1 in 7 dupilumab-treated patients.
