INTRODUCTION: Before the availability of biologic therapies, the main treatment for patients with severe asthma in Asia, Latin America, and the Middle East was oral corticosteroids (OCS), despite long-term use causing serious adverse effects. This post hoc analysis of the NUCALA Effectiveness Study (NEST) evaluated the effectiveness of mepolizumab, an anti-interleukin-5 monoclonal antibody, in patients with severe asthma and OCS dependence from regions with limited representation in real-world studies.
METHODS: NEST was a multicountry, observational cohort study in adults with severe asthma from Colombia, Chile, India, Türkiye, Saudi Arabia, United Arab Emirates, Kuwait, Oman, and Qatar. Patients received ≥ 1 dose of 100 mg mepolizumab. OCS dependence was defined as receiving maintenance OCS at mepolizumab initiation or for ≥ 26 weeks during the 12 months prior. Data were collected 12 months pre- and post-initiation. Outcomes included OCS use, rate of clinically significant exacerbations (CSEs), and level of asthma symptom control.
RESULTS: Of 524 patients with OCS use data, 58.4% (n = 306) had OCS dependence pre-initiation. Mean (standard deviation) age was 49.2 (13.4) years; 73.9% (n = 226) were women. Of 251 patients with available data, 87.6% (n = 220) received lower OCS doses post-initiation and 68.9% (n = 173) stopped OCS use altogether. CSEs were reduced by 76.9% post-initiation. Of 222 patients with available data, 72.5% (n = 161) had improvements in Asthma Control Test scores post-initiation.
CONCLUSION: In patients with severe asthma and OCS dependence from the countries studied, mepolizumab reduced OCS use and dose, asthma exacerbations, and improved symptom control.
