Trial overview
Official title: Effectiveness of Nucala in Severe Eosinophilic Asthma in Japan using MDV
Trial description: The Japanese Ministry of Health, Labor and Welfare approved NUCALA® (mepolizumab) in March 2016 for treatment of participants with refractory asthma. Mepolizumab has been shown to reduce asthma exacerbations by greater than 50 percent (%) in participants with severe asthma in clinical trials. This is a retrospective observational study to assess the changes in asthma exacerbations among participants who have 12 months of continuous enrolment prior to and following the date of first mepolizumab administration (index date) by using real-world data derived from the Medical Data Vision (MDV) database. This study will also analyze treatments and healthcare costs associated with asthma exacerbations. Participants who administered mepolizumab between 07-Jun-2016 and 30-Sep-2018 will be included. NUCALA is a registered trademark of GlaxoSmithKline group of companies.
