However, its real-life effectiveness for COPD has not been evaluated. This study compared the clinical effectiveness of BDP/FF against other licensed ICS/LABA combination inhalers: the Seretide® Accuhaler® (FP/SAL) and the Symbicort® Turbohaler® (BUD/FF). Methods: A matched historical cohort study was conducted using records of patients with diagnostic codes for COPD from the Optimum Patient Care Research Database (OPCRD). Patients who had received BDP/FF as their first ICS/LABA were matched 1:1 with patients who had received FP/SAL or BUD/FF, resulting in two matched comparisons. Additional analysis was conducted on patients who had never had diagnostic codes for asthma. Noninferiority in terms of the proportion of patients with moderate/severe COPD exacerbations on the different inhalers in the following year was assessed. Noninferiority was achieved if the upper CI limit were ≤1.2. Results: This study included 537 and 540 patient pairs in the BDP/FF vs FP/SAL cohort and the BDP/FF vs BUD/FF cohort, respectively. The proportion of patients with COPD exacerbations in the BDP/FF group was not significantly different from either the FP/SAL (68.7% vs 70.2%, AOR 0.89, 95% CI 0.67–1.19) or BUD/FF group (68.5% vs 69.4%, AOR 0.79, 95% CI 0.58–1.08). Noninferiority of BDP/FF in preventing COPD exacerbations was fulfilled in both comparisons. In patients without asthma, BDP/FF was also noninferior to BUD/FF (proportion with COPD exacerbations, 67.8% vs 64.7%, AOR 0.79, 95% CI 0.51– 1.1997). Additionally, a significantly lower proportion of patients prescribed BDP/FF had COPD exacerbations than FP/SAL (64.8% vs 73.7%, AOR 0.64 95% CI 0.43–0.96). Conclusion: Initiating ICS/LABA treatment of COPD with extrafine-formulation BDP/ FF was noninferior in preventing moderate/severe exacerbations compared to FP/SAL and BUD/FF.
