RESUMEN
OBJECTIVES: The IMPACT trial has compared the benefit in the reduction of moderate/severe exacerbations of single inhaler triple therapy (SITT) with fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) versus dual therapy with FF/VI (ICS/LABA) and UMEC/VI (LAMA/LABA) in the treatment of patients with chronic obstructive disease (COPD). This study performs a subgroup analysis of the cohort from Spain in the IMPACT study. MATERIALS AND METHODS: In IMPACT, a 52-week randomized, double-blind, parallel-group, multicenter study (N = 10,355), patients ⩾40 years of age with COPD and ⩾1 moderate/severe exacerbations in the previous year were randomized 2:2:1 to once-daily FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg or UMEC/VI 62.5/25 µg administered via the Ellipta inhaler. Here, we present a subgroup analysis of the 499 patients from Spain, included in the intent-to-treat (ITT) population in the study. Endpoint assessed included exposure-adjusted rate of moderate and severe exacerbations. RESULTS: In the Spain cohort, the exposure-adjusted rate of on-treatment moderate/severe COPD exacerbations per year for FF/UMEC/VI was 1.31 versus 1.43 and 1.57 for FF/VI and UMEC/VI, respectively. No new adverse events were identified. The results are consistent with those observed in the overall ITT study population. CONCLUSION: In the Spain cohort of the IMPACT study, patients receiving triple therapy with FF/UMEC/VI had a lower exposure-adjusted rate of exacerbations compared with FF/VI and UMEC/VI, similar to the overall population.Study Title: A Phase III, 52 Week, Randomized, Double-blind, 3-arm Parallel Group Study, Comparing the Efficacy, Safety and Tolerability of the Fixed Dose Triple Combination FF/UMEC/VI With the Fixed Dose Dual Combinations of FF/VI and UMEC/VI, All Administered Once-daily in the Morning Via a Dry Powder Inhaler in Subjects With Chronic Obstructive Pulmonary DiseaseURL: https://www.clinicaltrialsregister.eu/ctr-search/search?query=CTT116855/ https://clinicaltrials.gov/ct2/show/NCT02164513Registration number: GSK (CTT116855/NCT02164513).The reviews of this paper are available via the supplemental material section.
