Abstract
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.
期刊介绍：
The Journal of Allergy and Clinical Immunology is a prestigious publication that features groundbreaking research in the fields of Allergy, Asthma, and Immunology. This influential journal publishes high-impact research papers that explore various topics, including asthma, food allergy, allergic rhinitis, atopic dermatitis, primary immune deficiencies, occupational and environmental allergy, and other allergic and immunologic diseases. The articles not only report on clinical trials and mechanistic studies but also provide insights into novel therapies, underlying mechanisms, and important discoveries that contribute to our understanding of these diseases. By sharing this valuable information, the journal aims to enhance the diagnosis and management of patients in the future.
