Transforming COPD Management: The Evolving Role of Biologic Therapies
The arrival of biologic therapies represents a turning point in chronic obstructive pulmonary disease care, with agents such as mepolizumab and dupilumab poised to redefine treatment of eosinophilic and type 2 inflammatory phenotypes.
Conventional inhaled regimens and systemic corticosteroids have often provided inadequate control for patients with persistent inflammation, driving interest in targeted interventions. Recent studies highlighting mepolizumab underscore its effectiveness in targeting eosinophilic COPD, marking a departure from one-size-fits-all approaches to disease management and offering hope for patients with elevated eosinophil counts.
This tension is compounded by variable responses across COPD phenotypes, where targeted antibodies can address underlying pathobiology. Mepolizumab selectively binds interleukin-5, depleting eosinophils that contribute to exacerbations, while dupilumab inhibits interleukin-4 and interleukin-13 signaling to modulate type 2 inflammation. As noted in earlier findings, dupilumab has demonstrated efficacy in type 2 inflammatory COPD, reflecting personalized medicine’s advance in pulmonology. These mechanisms illustrate how biologics enable personalized COPD treatment by precisely interrupting the cytokine cascades driving each phenotype.
In clinical practice, a 65-year-old former smoker with recurrent exacerbations and blood eosinophils above 300 cells/µL achieved a 50% reduction in exacerbation rate after initiating mepolizumab; however, this reflects an isolated case rather than typical outcomes, and broader clinical data should be considered for a comprehensive assessment.
Biologic therapies herald a new era in COPD care, yet questions remain regarding long-term safety, cost-effectiveness, and equitable access. As broader use unveils additional patient subsets, pulmonologists must adapt practice patterns and maintain vigilance in identifying candidates for these advanced therapies.
