Effektivität von Dupilumab bei COPD-Patienten: Paradigmenwechsel in der Therapie?

Background: Previous randomized controlled trials have established the efficacy of dupilumab among patients with chronic obstructive pulmonary disease (COPD) treated with triple therapy over 52 weeks of follow-up. Objective: This population-based cohort study aimed to explore the long-term safety and effectiveness of dupilumab in patients with COPD. Methods: The study included US patients with COPD who were seen between April 2017 and August 2024. Patients initiating dupilumab and therapies that incorporated long-acting β2-agonist (LABA) inhalers were included. Patients with asthma or lung cancer were excluded. The risk of outcomes occurring after 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. Results: A total of 1521 dupilumab initiators and 1521 propensity score-matched patients who were receiving LABA-based therapies were included. Receiving dupilumab was associated with lower all-cause mortality (hazard ratio [HR] = 0.53, 95% CI = 0.43-0.65), fewer emergency department visits (HR = 0.78, 95% CI = 0.69-0.89), and lower acute exacerbation rates (HR = 0.59, 95% CI = 0.53-0.65). Dupilumab was also associated with reductions in the requirement for short-acting β2-agonists (HR = 0.48, 95% CI = 0.43-0.52) and short-acting muscarinic antagonists (HR = 0.43, 95% CI = 0.37-0.49) for symptom control. Additionally, dupilumab decreased rates of 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). Conclusions: In patients with COPD, dupilumab was associated with a lower mortality rate, fewer emergency department visits, and a reduced risk of acute exacerbations, respiratory symptoms, and respiratory infections. More studies are needed to validate the efficacy of dupilumab among patients with COPD of various severities.
