ABSTRACT: Purpose
Patients with severe asthma are eligible for asthma-specific biologics as add-on therapies, such as mepolizumab and omalizumab, when optimized controller therapies are unable to control their symptoms. However, few real-world data are available to describe the characteristics and associated economic burden of patients considered to be candidates for mepolizumab or omalizumab therapy.Methods
This retrospective cohort study investigated patients with asthma (?12 years of age) identified at the time of first mepolizumab or omalizumab administration (index date) in the MarketScan™ Commercial Database. Data were collected during the 12-month period before the index date (baseline period) for two mutually exclusive patient groups (patients prescribed mepolizumab and omalizumab, respectively). Baseline demographics, history of exacerbations, healthcare resource utilization (HCRU), and medical costs were investigated.Results
In total, 413 and 1,834 patients who had been prescribed mepolizumab or omalizumab, respectively, were identified. During the baseline period, patients prescribed mepolizumab experienced more exacerbations (81.4% vs 57.5%, P<0.001), had higher asthma-related HCRU for outpatient services (all P<0.01), and had higher total asthma-related healthcare costs (US$11,000 vs US$7,400, P<0.001) compared with patients prescribed omalizumab. Allergic rhinitis, atopic dermatitis, and chronic idiopathic urticaria were more common among patients prescribed omalizumab vs mepolizumab. In contrast, sinusitis, nasal polyps, and comorbid COPD were more common among patients prescribed mepolizumab vs omalizumab. Prescriptions of fixed-dose inhaled corticosteroids (ICSs) with long-acting ?2-agonists (LABAs) and ICS/LABA/long-acting muscarinic antagonist triple therapy during the baseline period were higher among patients prescribed mepolizumab vs omalizumab (80.4% vs 56.8% and 27.1% vs 14.4%, respectively, both P<0.001).Conclusion
In the 12 months prior to initiation of asthma-specific biologics, patients prescribed mepolizumab had a different prevalence of certain comorbidities, higher disease burden, higher HCRU, and higher healthcare costs compared with patients prescribed omalizumab.
