The Benefit of Benralizumab Monoclonal Antibody Treatment for Severe Eosinophilic Asthma in a Case Series (Pulmonology Clinic Târgu Mureș, Romania)

Background: Monoclonal antibody therapy is currently an additional treatment option to reduce exacerbations and improve symptom control in patients with severe eosinophilic asthma (SEA) that is uncontrolled despite treatment with high-dose inhaled corticosteroids and long-acting beta-2 agonists. Benralizumab, a monoclonal antibody that binds to the interleukin-5 receptor (IL-5), significantly reduces symptoms and annual exacerbations, as well as the use of systemic corticosteroids in patients with SEA. However, few studies are available on the effectiveness of this biological treatment in real life. The aim of this case series was to evaluate the efficacy of benralizumab by analyzing changes in clinical parameters and blood eosinophils in patients with SEA.
