Dupilumab Treatment for Aspirin-Exacerbated Respiratory Disease in a Real-World Setting: Impact on Quality of Life and Healthcare Utilization.

Abstract

Background: Patients with aspirin-exacerbated respiratory disease (AERD) have difficult-to-treat asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) and often require treatment with biologic therapy for asthma or CRSwNP. Healthcare utilization in patients with AERD has not been well described since the advent of respiratory biologics.

Objective: To determine real-world healthcare utilization and quality of life among patients with AERD and to understand the impact of dupilumab, a monoclonal antibody targeting the interleukin 4 receptor, on patient-reported health outcomes and healthcare utilization.

Methods: We conducted a longitudinal survey study of 98 patients with AERD recruited from the Brigham and Women's Hospital AERD registry. Patients completed online questionnaires describing their medication history, healthcare utilization, and quality of life every 3 months for 2 years.

Results: At the end of 24 months, participants who were on dupilumab at the start of the study and those who started dupilumab had a significant reduction in the number of reported poor health days in the preceding month compared to patients not on dupilumab (P < .001 and P < .01, respectively). Participants on dupilumab and those who started dupilumab also had significantly lower overall sinonasal outcome test-22 and asthma control test scores compared to those not on dupilumab over 24 months (P < .05 for both groups).

Conclusion: Dupilumab therapy significantly improves health-related quality of life in patients with AERD, specifically as it pertains to patient assessment of days of overall poor health and quality of life related to sinonasal and asthma symptoms.
