Summary
The anti-interleukin-5 monoclonal antibody mepolizumab is approved as an add-on therapy in Europe, Canada, USA, and other countries, to standard of care for the treatment of patients with severe eosinophilic asthma. Mepolizumab has been shown to reduce exacerbation rates and dependency on oral corticosteroid use in clinical trials in patients with severe eosinophilic asthma compared with placebo, both in addition to standard of care. Other trials had also showed that treatment with mepolizumab resulted in significant improvements in quality of life (SGRQ) and asthma control (ACQ-5 score) . Mepolizumab has only recently been approved in Brazil. There is still no data regarding its efficacy and safety in the Brazilian population and it is important to emphasize that no Brazilian center participated in the previous large, international and multicentric phase III mepolizumab studies. Therefore, it is crucial to perform a local study in order to validate external results in the Brazilian population.
Description
Severe asthma is associated with substantial morbidity, mortality, health-care costs, and impaired quality of life. Recurrent asthma exacerbations are a major problem in some patients and can predominate in a subgroup with eosinophilic airway inflammation. Mepolizumab is a humanised monoclonal antibody against interleukin 5 that effectively inhibits eosinophilic airway inflammation.

Our group belongs to a public academic institution with a focus on assistance, teaching and research. It is a tertiary-referral hospital with an outpatient clinic specializing severe asthma patients. In 2012, the investigators published the first study with the clinical characterization of their cohort of severe asthma and its respective phenotypes. Since then, the investigators have carried out several studies in order to identify prognostic factors and interventions that could improve the control and quality of life of this population. Among them, there are the impact of weight control in asthma symptoms, evaluation of standardized and systematic protocol based on high doses of inhaled corticosteroid plus LABA and 2 weeks course of oral corticosteroids and pathophysiological studies based on bronchial biopsy samples from patients with severe asthma. Since obesity is a serious and prevalent problem in several severe asthma cohorts, another area of interest of the group is to assess the impact of physical activity on this population. Finally, it is important to mention the commitment of the group to evaluate the incorporation of new treatments in the severe asthma population within the Brazilian scenario as done in a specific publication to systematically evaluate the use of omalizumab in our center.
Therefore, the investigators consider that our center has full capacity to conduct a systematic evaluation study of the use of mepolizumab in the population of severe asthma. The investigators aimed to examine the effects of mepolizumab on quality of life, lung function, asthma symptoms and exacerbation rate in patients with severe eosinophilic asthma in a tertiary reference center in Brazil based on real world data.
