Takeaway

  • Budesonide-formoterol inhaler was as effective as fluticasone-salmeterol in reducing the incidence of moderate-severe exacerbations in patients with chronic obstructive pulmonary disease (COPD) who had ≥1 exacerbation in the year prior to treatment initiation.

  • However, budesonide-formoterol was found to be more effective in reducing the incidence of severe exacerbation and pneumonia than fluticasone-salmeterol, particularly in patients with higher blood eosinophil counts.

Why this matters

  • The findings could add a new dimension to treatment recommendations for the use of the initial long-acting beta2-agonist (LABA)-inhaled corticosteroid (ICS) combined inhaler.

Study design

  • The study included 86,224 patients with COPD (age, ≥50 years) who subsequently were new users of a LABA-ICS combination (2002-2018), identified from the UK Clinical Practice Research Datalink.

  • Efficacy outcomes: the occurrence of a first moderate or severe COPD exacerbation during follow-up and the incidence of a severe exacerbation.

  • Safety outcome: the occurrence of first severe pneumonia requiring hospitalisation.

  • Funding: Canadian Institutes of Health Research and the Canadian Foundation for Innovation.

Key results

  • The adjusted HR (aHR) of a first moderate or severe exacerbation with budesonide-formoterol relative to fluticasone-salmeterol was 0.98 (95% CI, 0.95-1.01).

  • Budesonide-formoterol vs fluticasone-salmeterol was associated with a lower risk of severe exacerbation (aHR, 0.92; 95% CI, 0.85-0.99).

  • The aHR of severe pneumonia requiring hospitalisation with budesonide-formoterol was 0.76 (95% CI, 0.70-0.83) which dropped to 0.62 (95% CI, 0.51-0.77) at a blood eosinophil count >300 cells/μL.

Limitations

  • Study used physician diagnoses to identify patients with COPD, which may have misclassified some patients with asthma.
