Abstract
BackgroundPrevious randomized controlled trials had established the efficacy of dupilumab among patients with chronic obstructive pulmonary disease (COPD) treated with triple therapy over 52 weeks of follow-up. ObjectiveThis population-based cohort study aimed to explore the long-term clinical effectiveness of dupilumab in COPD patients. MethodsThis population-based cohort study included U.S. patients with COPD between April 2017 and August 2024. Patients initiating dupilumab and therapies that incorporated long-acting β2-agonists (LABA) inhalers were included. Patients with asthma or lung cancer were excluded. The risk of outcomes after the initiation of dupilumab versus LABA-containing therapies was measured. For detailed Methods, please see the Methods section in this article's Online Repository at www.jacionline.org. ResultsA total of 1,521 dupilumab initiators and 1,521 propensity score-matched patients receiving LABA-based therapies were included. Dupilumab recipients were associated with lower all-cause mortality (HR:0.53, 95% CI:0.43-0.65), emergency visits (HR:0.78, 95% CI:0.69-0.89), and acute exacerbation (AE) rates (HR:0.59, 95% CI:0.53-0.65). Dupilumab was also associated with reductions in the requirement of short-acting β2-agonists (HR:0.48, 95% CI:0.43-0.52), short-acting muscarinic antagonists (HR:0.43, 95% CI:0.37-0.49) for symptoms control. Additionally, dupilumab decreased subsequent pneumonia (HR:0.65, 95% CI:0.50-0.86), and COPD-relevant comorbidities including new-onset heart failure (HR:0.69, 95% CI:0.53-0.90) and new-onset anxiety (HR:0.70, 95% CI:0.53-0.93). ConclusionsDupilumab was associated with a lower rate of mortality, emergency visits, reduced risk of AEs, respiratory symptoms, and respiratory infections in COPD patients. More studies are required to validate the effectiveness of dupilumab among patients with COPD across various severities.
