Background and objective: Benralizumab (Fasenra (TM)) has recently been approved as add-on maintenance treatment for adult patients with severe eosinophilic asthma inadequately controlled despite high-dosage inhaled corticosteroids plus long-acting beta(2)-agonists. We aimed to identify and describe the clinical characteristics and disease burden of patients with severe, uncontrolled, eosinophilic asthma in France who may be eligible for treatment with benralizumab. Patients and methods: This was a retrospective analysis of a prospective, noninterventional, observational study of patients in France enrolled in the Asthma and Bronchial Obstruction Cohort (COBRA). First, we selected adult patients with severe asthma, a documented blood eosinophil count, 12 months of baseline data, and 12 months of follow-up data. Of these study-eligible patients, we next determined the prevalence and described the clinical characteristics and disease burden of patients who would be eligible to receive benralizumab, namely those with >= 2 asthma exacerbations in the previous 12 months and a blood eosinophil count >= 300/mu L who were receiving high-dosage inhaled corticosteroids/long-acting beta(2)-agonists. Results: Of the 441 patients eligible for this study, 85 (19%) met the criteria for benralizumab therapy. At study inclusion, benralizumab-eligible patients had a smaller prebronchodilator forced expiratory volume in 1 second and less effective asthma control compared with benralizumab-ineligible patients. During the 12-month follow-up period, benralizumab-eligible patients had greater frequencies of asthma exacerbations and hospitalizations compared with benralizumab-ineligible patients. Conclusion: Of patients with severe asthma, approximately 20% were qualified for benralizumab treatment. Benralizumab-eligible patients had increased bronchial obstruction, worse asthma control, and a greater frequency of asthma exacerbations and hospitalizations during follow-up care compared with benralizumab-ineligible patients, demonstrating inadequate disease control for these patients.
