Abstract
ABSTRACT
Background
Aspirin‐exacerbated respiratory disease (AERD), also termed nonsteroidal anti‐inflammatory drug exacerbated respiratory disease (NERD), is characterized by asthma, chronic rhinosinusitis with nasal polyposis, and hypersensitivity to cyclooxygenase‐1 inhibitors, frequently resulting in severe, treatment‐refractory airway disease. Biologic therapies targeting type 2 inflammation are increasingly used in AERD; though their relative efficacy remains incompletely defined.
Methods
We conducted a semi‐systematic narrative review of biologic therapies in AERD, guided by established narrative review frameworks. PubMed/Medline, ScienceDirect, and
ClinicalTrials.gov
were searched for studies reporting clinical outcomes in AERD/NERD or clearly defined AERD/NERD subgroups. This review synthesizes current evidence and presents an evidence‐informed clinical framework to support biologic selection in patients with AERD.
Results
Eighteen studies identified, including randomized controlled trials, observational studies, and real‐world studies. Across these studies, dupilumab was most consistently associated with improvements in both upper and lower airway outcomes. Anti–IL‐5 and anti–IL‐5Rα therapies reduced eosinophilia and asthma exacerbations, with variable sinonasal benefit. Omalizumab demonstrated efficacy in selected atopic phenotypes and in conjunction with aspirin therapy following desensitization. Emerging subgroup data suggests that Tezepelumab may reduce asthma exacerbations in AERD.
Conclusions
Current evidence suggests biologic therapies provide meaningful benefit in AERD, although available evidence is limited by small sample sizes and heterogeneous designs. Prospective comparative studies are needed to inform optimal biologic selection and sequencing.
