Samenvatting

Purpose: The 24-week INTREPID trial demonstrated the clinical benefits of once-daily single-inhaler triple therapy (SITT) with fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) versus non-ELLIPTA multiple-inhaler triple therapy (MITT) in patients with symptomatic chronic obstructive pulmonary disease (COPD). This analysis assessed the cost-effectiveness of FF/UMEC/VI versus non-ELLIPTA MITT for the treatment of symptomatic COPD from a United Kingdom (UK) National Health Service (NHS) perspective.

Patients and Methods: The analysis was conducted using the validated GALAXY COPD disease progression model. Baseline characteristics, treatment effect parameters (forced expiratory volume in 1 second and St. George’s Respiratory Questionnaire score [derived from exploratory COPD Assessment Test score mapping]), and discontinuation data from INTREPID were used to populate the model. UK healthcare resource and drug costs (2020 British pounds) were applied, and costs and outcomes were discounted at 3.5%. Analyses were conducted over a lifetime horizon from a UK NHS perspective. Model outputs included exacerbation rates, total costs, life years (LYs), quality-adjusted LYs (QALYs) and incremental cost-effectiveness ratio per QALY. Sensitivity analyses were conducted to assess the robustness of the results by varying parameter values and assumptions.

Results: Over a lifetime horizon, FF/UMEC/VI provided an additional 0.174 (95% confidence interval [CI]: 0.024, 0.344) LYs (approximately 2 months), and 0.253 (95% CI: 0.167, 0.346) QALYs (approximately 3 months), at a cost saving of £1764 (95% CI: −£2600, −£678) per patient, compared with non-ELLIPTA MITT. FF/UMEC/VI remained the dominant treatment option, meaning greater benefits at lower costs, across all scenario and sensitivity analyses.

Conclusion: Based on this analysis, in a UK setting, FF/UMEC/VI would improve health outcomes and reduce costs compared with non-ELLIPTA MITT for the treatment of patients with symptomatic COPD. SITT may help to reduce the clinical and economic burden of COPD and should be considered by physicians as a preferred treatment option.
