Official title: Health care resource use and costs associated with use of mepolizumab versus placebo in a clinical trial setting
Trial description: Estimating the economic impact of clinically significant exacerbations in patients with severe asthma can help payers make more informed decisions about the management of the severe eosinophilic asthma. The MEA115588 study (a Phase 3 clinical trial of mepolizumab + standard of care (SOC) versus placebo + SOC) provides an opportunity to assess, quantify, and evaluate health care resource use (HCRU) associated with a new therapy. The clinical trial data, combined with cost data from major United States (US) payers, will allow a comparison of cost estimates associated with exacerbations in patients with recurrent severe asthma with signs of eosinophilic inflammation based on randomized treatments. The primary objective of this study is to estimate the incremental asthma exacerbation-related medical costs (defined as costs associated with exacerbations requiring treatment with oral corticosteroids (OCS) or treatment in an emergency department (ED) or a hospitalization) for patients receiving mepolizumab+SOC compared to those receiving placebo+SOC based results from the MEA115588 study. The secondary objective is to estimate the asthma exacerbation-related ED visit/Hospitalization costs for patients receiving mepolizumab+SOC compared to those receiving placebo+SOC based on the MEA115588 study.The current study will be a post-hoc analysis of the MEA115588 trial data where patients with history of recurrent severe asthma exacerbations were randomized to receive mepolizumab versus placebo. However, this protocol finalization will be prior to SAC (statistical analyses complete) milestone for the MEA115588 study hence will represent an a priori analysis. The study is limited to an analysis of direct medical health care costs applied to the rates of HCRU associated with asthma-related exacerbations reported in the MEA115588 clinical trial. A unit-cost method (using standardized costs) will be used to calculate direct medical costs. Each HCRU will be assigned cost weights based on the unit costs estimates.
