Trial overview
Official title: Changes in Oral Corticosteroid Use Following Initiation of Mepolizumab Therapy in Patients with Asthma
Trial description: Asthma is a common chronic respiratory disorder that affects millions of children and adults in the United States (U.S). Asthma is characterized by periodic exacerbations by chronically hyperactive and inflamed airways that can be mild, moderate, or severe. The U.S. Food and Drug Administration (FDA) approved Nucala (mepolizumab) in November-2015 for add-on maintenance treatment in subjects 12 years or older with severe asthma. Mepolizumab is a humanized interleukin-5 antagonist monoclonal antibody administered by subcutaneous injection by a health care professional via subcutaneous injection in a hospital outpatient setting, infusion center, or physician’s office. It is critical to understand the real-world impact of mepolizumab on OCS. This retrospective observational study will investigate impact of mepolizumab on OCS use by comparing the year prior to the administration of mepolizumab to the year after using a commercial insurance database. The MarketScan Commercial Claims and Encounters Database will be used for this study.

- Subjects with mepolizumab administration between 01-November-2015 and 30-September-2017. The date of the first claim for mepolizumab during the patient identification period will be considered as the index date.
- Subjects with at least 12 months of continuous enrollment with medical and pharmacy benefits before the index date (baseline period).
- Subjects with evidence of mepolizumab use during the 12-month baseline period.
- Subjects with evidence of omalizumab, reslizumab, benralizumab, or dupilumab use (as assessed by Healthcare Common Procedure Coding System (HCPCS) or National Drug Code (NDC) codes) during the 12-month baseline or follow-up period.

- Subjects with least 12 months of continuous enrollment with medical and pharmacy benefits after the index date (follow-up period).
- Subjects with at least 12 years of age on the index date.
- Subjects with more than 1 asthma diagnosis (International Classification of Diseases ([CD]-9: 493.xx, ICD-10: J45.xx) in any position on a non-diagnostic medical claim during the 12-month baseline period.
- Subjects with more than or equal to 2 mepolizumab administrations during the first 6 months of the follow-up period.
