Abstract

Introduction: Phenotyping allergic rhinitis (AR) by immunoglobulin E (IgE) sensitivity and comorbidities may help characterize AR and provide a framework for treatment decisions. Methods: This prospective, noninterventional study evaluated the effectiveness of MP-AzeFlu (azelastine hydrochloride plus fluticasone propionate intranasal spray formulation) across AR phenotypes. Patients with moderate-to-­severe seasonal or perennial AR for whom MP-AzeFlu was prescribed were enrolled. AR subpopulations (ARPs) were assigned based on the classification of IgE response and comorbidities. AR symptoms over the previous 24 h were documented using an AR visual analog scale (AR-VAS), with ratings from “not at all bothersome” (0 mm) to “extremely bothersome” (100 mm), at the inclusion visit and on days 1, 3, 7, and the last day of the study (approximately day 14). AR quality-of-life measures were recorded using a VAS. Results: A total of 1,103 patients with AR were included. Mean baseline AR-VAS scores ranged from 70.3 to 75.1 mm (severe) across ARPs. In the overall population, 86.6% of patients responded to treatment (AR-VAS score <50 mm on ≥1 days). In the ARPs, response rates ranged from 79.3 to 89.6%. Mean reduction in AR-VAS scores ranged from 47.9 to 40.9 mm, a decrease from severe to mild across all ARPs. Quality-of-life VAS scores were similarly reduced in the total population and ARPs. Discussion/Conclusion: MP-AzeFlu treatment reduced VAS severity and quality-of-life scores from baseline in the total population and ARPs, supporting MP-AzeFlu as an effective treatment for all patients with moderate-to-severe AR, regardless of AR phenotype or comorbidities.
