To compare outcomes in people who stopped or continued asthma biologics. We identified a cohort of people with asthma who stopped or continued asthma biologics in the Optum Labs Database Warehouse, using a propensity matching method for case and control groups with the variables of age, sex, race, region, insurance, income, specialist access, Charlson comorbidity, specific medical conditions, pre-index exacerbation count, pre-index rescue inhaler pharmacy fills, and pre-index inhaled corticosteroid with or without long-acting β-agonist pharmacy fills. Primary outcome used to assess failure of stopping was an increase of 50% or more in the asthma exacerbation rate in the 6 months after discontinuing the biologic compared with the 6-month period before biologic initiation. Among a cohort of 4960 asthma biologic users, 1249 were observed to stop use after 6 to 12 months of use. We identified a matched cohort of 1247 stoppers and 1247 people who continued biologic use for at least 18 months. In the first 6 months after stopping or sham stopping, 10.2% of stoppers and 9.5% of continuers had an increase of 50% or more in asthma exacerbations. We found a similar adjusted odds of failing among stoppers and continuers (odds ratio= 1.085; 95% confidence interval, 0.833-1.413). An increase in asthma exacerbations is infrequently observed in people who stopped asthma biologics and was observed at similar rates as in matched controls who continued asthma biologics.
