Real-world effectiveness of umeclidinium/vilanterol versus fluticasone propionate/salmeterol as initial maintenance therapy for chronic obstructive pulmonary disease (COPD): a retrospective cohort study.
Int J Chron Obstruct Pulmon Dis 2019; 14:1721-1737IJ

Abstract

Background and objective

Retrospective claims data in patients with chronic obstructive pulmonary disease (COPD) initiating maintenance therapy with inhaled fixed-dose combinations of long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) versus inhaled corticosteroid (ICS)/LABA have not been reported.

Methods

Retrospective observational study in a COPD-diagnosed population of commercial and Medicare Advantage with Part D (MAPD) enrollees aged ≥40 years from a US health insurer database. Patients initiated umeclidinium/vilanterol (UMEC/VI [62.5/25 µg]) or fluticasone propionate/salmeterol (FP/SAL [250/50 µg]) between April 1, 2014 and August 31, 2016 (index date) and had 12 months continuous enrollment pre- and post-index. Exclusion criteria included an asthma diagnosis in the pre-index period/index date; ICS-, LABA-, or LAMA-containing therapy during the pre-index period; or pharmacy fills for both UMEC/VI and FP/SAL, multiple-inhaler triple therapy, a non-index therapy, or COPD exacerbation on the index date. Adherence (proportion of days covered [PDC] ≥80%) was modeled using weighted logistic regression following inverse probability of treatment weighting (IPTW). Weighted Kaplan-Meier and Cox proportional hazards regression following IPTW were performed for incidence of COPD exacerbation and escalation to multiple-inhaler triple therapy.

Results

The study population included 5306 patients (1386 initiating UMEC/VI and 3920 initiating FP/SAL). Adjusted odds of adherence were 2.00 times greater among UMEC/VI than FP/SAL initiators (95% confidence interval [CI]: 1.62─2.46; P<0.001). The adjusted hazard ratio (HR) for first exacerbation was 0.87 (95% CI: 0.74-1.01; P=0.067) among UMEC/VI versus FP/SAL initiators. UMEC/VI initiators had 35% lower adjusted risk of escalation to multiple-inhaler triple therapy (HR 0.65; 95% CI: 0.47-0.89; P=0.008) versus FP/SAL. On-treatment, UMEC/VI initiators had an adjusted 30% reduced risk of a first moderate/severe COPD exacerbation (HR 0.70; 95% CI: 0.54-0.90; P=0.006).

Conclusion

Patients with COPD initiating UMEC/VI had higher adherence and longer time before escalation to multiple-inhaler triple therapy than FP/SAL initiators.
