Eosinophilic and Noneosinophilic Asthma
2021
Background Phenotypic characteristics of patients with eosinophilic and noneosinophilic asthma are not well characterized in global, real-life severe asthma cohorts. Research Question What is the prevalence of eosinophilic and noneosinophilic phenotypes in the population with severe asthma, and can these phenotypes be differentiated by clinical and biomarker variables? Study Design and Methods This was an historical registry study. Adult patients with severe asthma and available blood eosinophil count (BEC) from 11 countries enrolled in the International Severe Asthma Registry (January 1, 2015-September 30, 2019) were categorized according to likelihood of eosinophilic phenotype using a pre…
Effective Management of Severe Asthma with Biologic Medications in Adult Patients: A Literature Review and International Expert Opinion
2021
International audience; Severe asthma often remains uncontrolled despite effective treatments and evidence-based guidelines. A group of global experts in asthma and biologic medications from nine countries considered the most relevant clinical variables to manage severe asthma in adult patients and guide treatment choice. The resulting recommendations address the investigation of biomarker levels (blood eosinophil count along with fractional concentration of exhaled nitric oxide [FeNO]), clinical features (oral corticosteroid [OCS] dependency, specific comorbid disease entities associated with severe type 2 asthma), and safety considerations. Current evidence suggests that biomarkers, inclu…
Characterising individual response to mepolizumab treatment
2020
Background: Patients with severe eosinophilic asthma (SEA) often have heterogenous phenotypes with periods of asthma worsening, making it difficult to assess mepolizumab treatment response. Aims: To define patient level variables for mepolizumab treatment response. Methods: In this post-hoc analysis we examined mepolizumab response in patients with SEA (≥2 exacerbations in prior year) in the 32-week, randomised, placebo-controlled MENSA study and the following 52-week, open-label COSMOS study. Patients who completed both studies and received mepolizumab throughout were included (n=311). Results: In MENSA, 67% and 21% of patients had 0 or 1 exacerbations, respectively, and were considered re…
