BACKGROUND: Real-world evidence characterizing the clinical outcomes and economic impact on patients with severe eosinophilic asthma treated with benralizumab is limited.
OBJECTIVE: To characterize patients with severe asthma treated with benralizumab and assess its clinical and economic impact in the United States.
METHODS: A pre-post benralizumab comparison was performed using a large US insurance claims database between November 2016 and November 2019. The primary cohort included patients with asthma aged 12 years or more with 2 or more records of benralizumab. Secondary cohorts included persistent users (6 or more records of benralizumab), patients switching to benralizumab from mepolizumab or omalizumab, and stratified by Medicaid vs non-Medicaid. Exacerbations, concomitant medications, and exacerbation-related health care resource utilization (HCRU) and costs were compared in the 12-month periods pre- and post-benralizumab initiation (index).
RESULTS: Of the 204 patients in the primary cohort, mean age at index was 45.3 years and 68.6% were of female sex. The patients experienced a significant 55% reduction in rates of exacerbations post-benralizumab initiation (3.25 pre-index vs 1.47 post-index per person-year; P < .001), and 41% of the patients had no exacerbations post-benralizumab initiation. The proportion of oral corticosteroid-dependent patients decreased from 82% to 50% (P < .001). Reductions in HCRU were 42%, 46%, and 57% for asthma exacerbation-related inpatient hospitalizations, emergency department, and outpatient visits, respectively (all P < .001). Exacerbation-related costs decreased by $6439 ($13,559 vs $7120; P < .001). Similar results for all outcomes were observed for the persistent cohort, switch cohorts, and Medicaid vs non-Medicaid cohorts.
CONCLUSION: Patients with severe asthma treated with benralizumab experienced clinical and economic benefits in the real world, as demonstrated by the reduction in exacerbations and HCRU.
