Background Real-world evidence comparing long-acting muscarinic antagonist/long-acting β2-agonist dual therapies on acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is limited.

Aim and Objectives To compare AECOPD rates in patients newly initiating single-inhaler umeclidinium/vilanterol (UMEC/VI) or indacaterol/glycopyrronium (IND/GLY) in England.

Methods Retrospective cohort study using linked primary and secondary healthcare data. Non-inferiority (NI; 10% pre-defined margin) of UMEC/VI versus IND/GLY on rate of AECOPDs (moderate-to-severe, moderate, severe) was assessed in patients indexed on initiation of single-inhaler UMEC/VI or IND/GLY (01/2015–09/2019) at 6, 12 and 18 months post-index. Inverse probability of treatment weighting (IPTW) was used to balance treatment groups on potential confounders.

Results In 12 031 eligible patients (UMEC/VI: 8753; IND/GLY: 3278), weighted AECOPD rates with UMEC/VI versus IND/GLY were below the pre-specified NI margin at all time points and significantly lower at 6 months for severe AECOPD. Unweighted analyses were similar. Groups were well balanced on potential confounders after IPTW.

Conclusions Newly prescribed UMEC/VI was non-inferior to IND/GLY on rate of moderate-to-severe, moderate, and severe AECOPD in patients with COPD in England.

Funding GSK (study 214887)

Tab. 1 aThe pre-specified NI margin was 10%, which meant that the UMEC/VI cohort could have at most a 10% greater rate of AECOPDs versus IND/GLY (corresponding to a rate ratio of 1.1) to demonstrate NI.
