BACKGROUND: In the United States, dupilumab is approved for moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma, and omalizumab is approved for managing moderate-to-severe allergic asthma uncontrolled by inhaled corticosteroids. However, limited comparative effectiveness data exist for these biologics due to differing patient characteristics and treatment histories.
OBJECTIVE: This study assessed the real-world effectiveness of dupilumab and omalizumab for asthma in patients in the United States.
METHODS: In this retrospective observational study, TriNetX Dataworks electronic medical record data were used to identify patients with asthma age ≥12 years who initiated (index) dupilumab or omalizumab between November 2018 and September 2020 and who had at least 12 months of pre- and post-index clinical information. Inverse probability of treatment weighting was applied to balance potential confounding in treatment groups. Asthma exacerbation rates and systemic corticosteroid (SCS) prescriptions were compared using a doubly robust negative binomial regression model, adjusting for baseline exacerbation/SCS rates and patient characteristics with ≥10% standardized differences after inverse probability of treatment weighting.
RESULTS: All inclusion and exclusion criteria were met by 2138 dupilumab patients and 1313 omalizumab patients. After weighting, the majority of baseline characteristics were balanced (standard difference <10%) between the 2 groups. Dupilumab was associated with a 44% lower asthma exacerbation rate (P < .0001) versus omalizumab. Additionally, dupilumab treatment significantly (P < .05) reduced SCS prescriptions by 28% during the follow-up period compared with omalizumab treatment.
CONCLUSIONS: The US ADVANTAGE real-world study demonstrated a significant reduction in severe asthma exacerbations and SCS prescriptions for patients prescribed dupilumab compared with patients prescribed omalizumab during 12 months of follow-up.
