Integrating Selective Targeted Monoclonal Antibody Therapies for Improved Outcomes in Uncontrolled Asthma

Abstract

Asthma is one of the most common chronic diseases, with ≤25% of patients experiencing uncontrolled disease.1Patients with uncontrolled, moderate-to-severe asthma are at increased risk of recurrent exacerbations, accelerated decline in lung function, fixed airway obstruction, and have increased utilisation of health care resources.2,3Furthermore, reduced lung function, as assessed by measures such as forced expiratory volume in 1 second (FEV1), is a strong independent predictor of exacerbations, progressive decline in lung function, and all-cause pulmonary and cardiovascular mortality in patients with asthma.2 Achieving asthma control in these patients is therefore critical. The recognition of distinct inflammatory phenotypes within this population has been instrumental in addressing this need. In these patients, there is robust evidence of the pathogenic role of Th2 cytokines, such as IL-4 and IL-13, in the eosinophilic and allergic inflammatory processes.4This in turn has driven the development of targeted biological therapies, particularly selective targeted monoclonal antibodies such as dupilumab which inhibit the biological effects of both IL-4 and IL-13.5 This article reviews four posters displayed at the European Respiratory Society (ERS) International Congress 2019 that presented results demonstrating the efficacy and safety of dupilumab, an anti-IL-4 receptor human monoclonal antibody, compared to placebo for the treatment of uncontrolled, moderate-to-severe asthma, as measured by a range of outcomes.
