N2 - Background: Biologic modifiers targeting type 2 (T2) airway inflammation are effective in reducing asthma exacerbation. However, real-world and comparative effectiveness studies remain limited. Objective: To examine and compare the real-world impact of anti-T2 asthma biologics. Methods: In this retrospective, new user cohort study, we used the MarketScan, a Commercial Claims and Encounters Database, to identify adult patients with asthma who began to receive an anti-T2 biologic agent (anti-IL-5s, dupilumab, or omalizumab). We examined the influence of the biologic class on asthma exacerbation by comparing the average number of asthma exacerbation 1 year before and after biologic initiation. We conducted multivariable regression analyses to compare the effectiveness of these asthma biologics on reducing the incidence of asthma exacerbations within 18 months of the initial administration of biologics while controlling for demographic variables, comorbidities, and asthma severity. Results: We identified 5,538 asthma patients who were new to taking an anti-T2 biologic [mean age [±SD], 45.6 (12.78) years; 65.8% female). Asthma biologics reduced asthma exacerbation by 11% to 47%, particularly among patients with two or more asthma exacerbations in the year preceding biologic initiation (31% to 65% reduction). Biologics were especially effective in reducing asthma-related hospitalizations (44.6% to 60%). After adjusting for baseline demographics, asthma medication, and comorbidities, dupilumab was associated with a lower estimated mean number of asthma exacerbation per year and lower adjusted odds ratio for developing an asthma exacerbation relative to other biologics (50% to 80% less likely). Conclusions: Anti-T2 asthma biologics reduced asthma exacerbation in real-word settings. Evidence supports growing literature reporting that dupilumab might have a more favorable impact on asthma exacerbation relative to other asthma biologics.
