RESUMEN
BACKGROUND: The benefits of triple therapy for chronic obstructive pulmonary disease (COPD) with an inhaled glucocorticoid, a long-acting muscarinic antagonist (LAMA), and a long-acting ß2-agonist (LABA), as compared with dual therapy (either inhaled glucocorticoid-LABA or LAMA-LABA), are uncertain. METHODS: In this randomized trial involving 10,355 patients with COPD, we compared 52 weeks of a once-daily combination of fluticasone furoate (an inhaled glucocorticoid) at a dose of 100 µg, umeclidinium (a LAMA) at a dose of 62.5 µg, and vilanterol (a LABA) at a dose of 25 µg (triple therapy) with fluticasone furoate-vilanterol (at doses of 100 µg and 25 µg, respectively) and umeclidinium-vilanterol (at doses of 62.5 µg and 25 µg, respectively). Each regimen was administered in a single Ellipta inhaler. The primary outcome was the annual rate of moderate or severe COPD exacerbations during treatment. RESULTS: The rate of moderate or severe exacerbations in the triple-therapy group was 0.91 per year, as compared with 1.07 per year in the fluticasone furoate-vilanterol group (rate ratio with triple therapy, 0.85; 95% confidence interval [CI], 0.80 to 0.90; 15% difference; P<0.001) and 1.21 per year in the umeclidinium-vilanterol group (rate ratio with triple therapy, 0.75; 95% CI, 0.70 to 0.81; 25% difference; P<0.001). The annual rate of severe exacerbations resulting in hospitalization in the triple-therapy group was 0.13, as compared with 0.19 in the umeclidinium-vilanterol group (rate ratio, 0.66; 95% CI, 0.56 to 0.78; 34% difference; P<0.001). There was a higher incidence of pneumonia in the inhaled-glucocorticoid groups than in the umeclidinium-vilanterol group, and the risk of clinician-diagnosed pneumonia was significantly higher with triple therapy than with umeclidinium-vilanterol, as assessed in a time-to-first-event analysis (hazard ratio, 1.53; 95% CI, 1.22 to 1.92; P<0.001). CONCLUSIONS: Triple therapy with fluticasone furoate, umeclidinium, and vilanterol resulted in a lower rate of moderate or severe COPD exacerbations than fluticasone furoate-vilanterol or umeclidinium-vilanterol in this population. Triple therapy also resulted in a lower rate of hospitalization due to COPD than umeclidinium-vilanterol. (Funded by GlaxoSmithKline; IMPACT ClinicalTrials.gov number, NCT02164513 .).

Rationale: In the IMPACT (Informing the Pathway of Chronic Obstructive Pulmonary Disease Treatment) trial, fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) significantly reduced exacerbations compared with FF/VI or UMEC/VI in patients with symptomatic chronic obstructive pulmonary disease and a history of exacerbations.Objectives: To understand whether inhaled corticosteroid (ICS) withdrawal affected IMPACT results, given direct transition from prior maintenance medication to study medication at randomization.Methods: Exacerbations and change from baseline in trough FEV1 and St. George's Respiratory Questionnaire results were analyzed by prior ICS use. Exacerbations were also analyzed while excluding data from the first 30 days.Measurements and Main Results: FF/UMEC/VI significantly reduced the annual moderate/severe exacerbation rate compared with UMEC/VI in prior ICS users (29% reduction; P < 0.001), but only a numerical reduction was seen among prior ICS nonusers (12% reduction; P = 0.115). To minimize impact from ICS withdrawal, in an analysis excluding the first 30 days, FF/UMEC/VI continued to significantly reduce the annual on-treatment moderate/severe exacerbation rate (19%; P < 0.001) compared with UMEC/VI. The benefit of FF/UMEC/VI compared with UMEC/VI was seen for severe exacerbation rates, regardless of prior ICS use (prior ICS users, 35% reduction; P < 0.001; non-ICS users, 35% reduction; P = 0.018), and overall when excluding the first 30 days (29%; P < 0.001). Improvements from baseline with FF/UMEC/VI compared with UMEC/VI were also maintained throughout the study for both trough FEV1 and St. George's Respiratory Questionnaire, regardless of prior ICS use.Conclusions: These data support the important treatment effects of FF/UMEC/VI combination therapy on exacerbation reduction, lung function, and quality of life that do not appear to be related to abrupt ICS withdrawal.Clinical trial registered with www.clinicaltrials.gov (NCT02164513).

Rationale: The IMPACT (Informing the Pathway of Chronic Obstructive Pulmonary Disease Treatment) trial demonstrated a significant reduction in all-cause mortality (ACM) risk with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus UMEC/VI in patients with chronic obstructive pulmonary disease (COPD) at risk of future exacerbations. Five hundred seventy-four patients were censored in the original analysis owing to incomplete vital status information.Objectives: Report ACM and impact of stepping down therapy, following collection of additional vital status data.Methods: Patients were randomized 2:2:1 to FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg, or UMEC/VI 62.5/25 µg following a run-in on their COPD therapies. Time to ACM was prespecified. Additional vital status data collection and subsequent analyses were performed post hoc.Measurements and Main Results: We report vital status data for 99.6% of the intention-to-treat population (n = 10,355), documenting 98 (2.36%) deaths on FF/UMEC/VI, 109 (2.64%) on FF/VI, and 66 (3.19%) on UMEC/VI. For FF/UMEC/VI, the hazard ratio for death was 0.72 (95% confidence interval, 0.53-0.99; P = 0.042) versus UMEC/VI and 0.89 (95% confidence interval, 0.67-1.16; P = 0.387) versus FF/VI. Independent adjudication confirmed lower rates of cardiovascular and respiratory death and death associated with the patient's COPD.Conclusions: In this secondary analysis of an efficacy outcome from the IMPACT trial, once-daily single-inhaler FF/UMEC/VI triple therapy reduced the risk of ACM versus UMEC/VI in patients with symptomatic COPD and a history of exacerbations.

IMPACT, a 52-week, randomised, double-blind trial, assessed the efficacy and safety of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy versus FF/VI or UMEC/VI in patients with symptomatic COPD and a history of exacerbations.Subgroup analyses assessed whether the efficacy of FF/UMEC/VI versus FF/VI or UMEC/VI and UMEC/VI versus FF/VI varies according to prior exacerbation history, and the combined effects of exacerbation history and blood eosinophil counts. Three subgroups were defined: single moderate (1 moderate/no severe; n=3056 (30%)), frequent moderate (≥2 moderate/no severe; n=4628 (45%)) and severe (≥1 severe/any moderate; n=2671 (26%)). End-points included annual on-treatment moderate/severe exacerbation rate (pre-specified), lung function and health status (both post-hoc).Moderate/severe exacerbation rates (reduction % (95% CI)) were reduced in the FF/UMEC/VI group versus FF/VI (single moderate 20% (10-29), frequent moderate 11% (2-19), severe 17% (7-26)) and versus UMEC/VI (single moderate 18% (5-29), frequent moderate 29% (21-37), severe 26% (14-35)). Moderate/severe exacerbation rates were reduced in the FF/VI group versus UMEC/VI in the frequent moderate subgroup; a numerical reduction was observed in the severe subgroup (single moderate 2% (-12-18), frequent moderate 21% (11-29), severe 11% (-3-22)). Moderate/severe exacerbation rates were lower in the FF/VI group compared with UMEC/VI in patients with higher eosinophil counts. FF/UMEC/VI improved lung function and health status versus both dual therapies irrespective of exacerbation subgroup. UMEC/VI improved lung function versus FF/VI in all subgroups.Triple therapy was more effective than dual regardless of exacerbation history, consistent with results in the intent-to-treat population. Comparisons between dual therapies were influenced by prior exacerbation history and eosinophil counts.

BACKGROUND: This analysis of the IMPACT study assessed the cardiovascular (CV) safety of single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI and UMEC/VI dual therapy. METHODS: IMPACT was a 52-week, randomized, double-blind, multicenter Phase III study comparing the efficacy and safety of FF/UMEC/VI 100/62.5/25 mcg with FF/VI 100/25 mcg or UMEC/VI 62.5/25 mcg in patients ≥40 years of age with symptomatic chronic obstructive pulmonary disease (COPD) and ≥1 moderate/severe exacerbation in the previous year. The inclusion criteria for the study were intentionally designed to permit the enrollment of patients with significant concurrent CV disease/risk. CV safety assessments included proportion of patients with and exposure-adjusted rates of on-treatment CV adverse events of special interest (CVAESI) and major adverse cardiac events (MACE), as well as time-to-first (TTF) CVAESI, and TTF CVAESI resulting in hospitalization/prolonged hospitalization or death. RESULTS: Baseline CV risk factors were similar across treatment groups. Overall, 68% of patients (n = 7012) had ≥1 CV risk factor and 40% (n = 4127) had ≥2. At baseline, 29% of patients reported a current/past cardiac disorder and 58% reported a current/past vascular disorder. The proportion of patients with on-treatment CVAESI was 11% for both FF/UMEC/VI and UMEC/VI, and 10% for FF/VI. There was no statistical difference for FF/UMEC/VI versus FF/VI or UMEC/VI in TTF CVAESI (hazard ratio [HR]: 0.98, 95% confidence interval [CI]: 0.85, 1.11; p = 0.711 and HR: 0.92, 95% CI: 0.78, 1.08; p = 0.317, respectively) nor TTF CVAESI leading to hospitalization/prolonged hospitalization or death (HR: 1.19, 95% CI: 0.93, 1.51; p = 0.167 and HR: 0.96, 95% CI: 0.72, 1.27; p = 0.760, respectively). On-treatment MACE occurred in ≤3% of patients across treatment groups, with similar prevalence and rates between treatments. CONCLUSIONS: In a symptomatic COPD population with a history of exacerbations and a high rate of CV disease/risk, the proportion of patients with CVAESI and MACE was 10-11% and 1-3%, respectively, across treatment arms, and the risk of CVAESI was low and similar across treatment arms. There was no statistically significant increased CV risk associated with the use of FF/UMEC/VI versus FF/VI or UMEC/VI, and UMEC/VI versus FF/VI.

RATIONALE: Many patients with chronic obstructive pulmonary disease (COPD) have an accelerated loss of lung function. It is unclear whether drug treatment can modify this in patients with moderately severe disease. OBJECTIVES: In a prespecified analysis of the key secondary outcome in SUMMIT (Study to Understand Mortality and Morbidity), we investigated whether the inhaled corticosteroid fluticasone furoate (FF; 100 µg), the long-acting ß-agonist vilanterol (VI; 25 µg), or their combination (FF/VI) modified the rate of decline in FEV1 compared with placebo. We also investigated how baseline covariates affected this decline. METHODS: Spirometry was measured every 12 weeks in this event-driven, randomized, placebo-controlled trial of 16,485 patients with moderate COPD and heightened cardiovascular risk. An average of seven spirometric assessments per subject among the 15,457 patients with at least one on-treatment measurement were used in the analysis of rate of FEV1 decline. All statistical comparisons are considered nominal. MEASUREMENTS AND MAIN RESULTS: The adjusted rates of FEV1 decline were -46 ml/yr (-3.0% of baseline) with placebo, -47 ml/yr (-3.1%) with VI, -38 ml/yr (-2.5%) with FF, and -38 ml/yr (-2.3%) with FF/VI. FF-containing regimens had lower rates of decline than placebo (P < 0.03), and FF/VI had a lower rate of decline than VI alone (P < 0.005). The FEV1 decline was faster in current smokers, those with a lower body mass index, males, and patients with established cardiovascular disease. CONCLUSIONS: In patients with moderate COPD and heightened cardiovascular risk, FF alone or in combination with VI appears to reduce the rate of FEV1 decline.

RATIONALE: Inhaled corticosteroids have been shown to decrease exacerbations in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Their effects in patients with milder airflow obstruction remain unclear. OBJECTIVES: This was an analysis of exacerbations in the SUMMIT (Study to Understand Mortality and Morbidity) study. METHODS: In a double-blind, randomized controlled trial, once-daily inhaled placebo, fluticasone furoate (FF; 100 µg), vilanterol (VI; 25 µg), or the combination of FF/VI was administered. The primary outcome was all-cause mortality. Exacerbations of COPD were an additional predefined endpoint. A total of 1,368 centers in 43 countries and 16,485 patients with moderate COPD and heightened cardiovascular risk were included in the study. MEASUREMENTS AND MAIN RESULTS: Compared with placebo, FF/VI reduced the rate of moderate and/or severe exacerbations by 29% (95% confidence interval [CI], 22-35; P < 0.001) and the rate of hospitalized exacerbations by 27% (95% CI, 13-39; P < 0.001). These relative effects were similar regardless of whether subjects had a history of exacerbation in the year before the study or an FEV1 <60% or ≥60% of predicted. The number needed to treat was not influenced by baseline FEV1 but was influenced by the history of exacerbations. FF/VI also reduced the rate of exacerbations treated with corticosteroids alone or with corticosteroids and antibiotics but not the rates of those treated with antibiotics alone. CONCLUSIONS: Patients with moderate chronic airflow obstruction experienced a reduction in exacerbations with FF/VI compared with placebo, irrespective of a history of exacerbations or baseline FEV1.

INTRODUCTION: Clinically important deterioration (CID) is a multicomponent measure for assessing disease worsening in chronic obstructive pulmonary disease (COPD). This analysis investigated the prognostic value of a CID event on future clinical outcomes and the effect of single-inhaler triple versus dual therapy on reducing CID risk in patients in the IMPACT trial. METHODS: IMPACT was a phase III, double-blind, 52-week, multicentre trial. Patients with symptomatic COPD and at least one moderate/severe exacerbation in the prior year were randomised 2:2:1 to fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25â µg, FF/VI 100/25â µg or UMEC/VI 62.5/25â µg. CID at the time-point of interest was defined as a moderate/severe exacerbation, ≥100â mL decrease in trough forced expiratory volume in 1â s or deterioration in health status (increase of ≥4.0â units in St George's Respiratory Questionnaire total score or increase of ≥2.0â units in COPD Assessment Test score) from baseline. A treatment-independent post hoc prognostic analysis compared clinical outcomes up to week 52 in patients with/without a CID by week 28. A prospective analysis evaluated time to first CID with each treatment. RESULTS: Patients with a CID by week 28 had significantly increased exacerbation rates after week 28, smaller improvements in lung function and health status at week 52 (all p<0.001), and increased risk of all-cause mortality after week 28 versus patients who were CID-free. FF/UMEC/VI significantly reduced CID risk versus dual therapies (all p<0.001). CONCLUSIONS: Prevention of short-term disease worsening was associated with better long-term clinical outcomes. FF/UMEC/VI reduced CID risk versus dual therapies; this effect may improve long-term prognosis in this population.
RESUMEN
Rationale: In the IMPACT (Informing the Pathway of COPD Treatment) trial, single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy reduced exacerbation risk versus FF/VI and UMEC/VI and mortality risk versus UMEC/VI. However, pneumonia incidence was higher in the inhaled corticosteroid (FF)-containing arms, raising questions about the relative benefit of exacerbation reduction compared with the increased risk of pneumonia.Objectives: Determine benefit-risk of the three treatments by evaluating time-to-first and rates of composite exacerbation or pneumonia outcomes.Methods: We evaluated time-to-first (prespecified) and rates (post hoc) of investigator-reported pneumonia, serious pneumonia leading to hospitalization or death, and the composite endpoints of 1) moderate (required antibiotics/corticosteroids)/severe (hospitalized) exacerbation or pneumonia and 2) severe exacerbation or serious (hospitalized) pneumonia. Analyses were repeated for radiographically confirmed pneumonia (post hoc).Results: Moderate/severe exacerbations occurred in 47%, 49%, and 50% of patients randomized to FF/UMEC/VI, FF/VI and UMEC/VI, and pneumonias in 8%, 7%, and 5%, respectively. FF/UMEC/VI reduced the risk of combined moderate/severe exacerbation or pneumonia (time-to-first) versus FF/VI (hazard ratio, 0.87 [95% confidence interval (CI), 0.82-0.92]) and UMEC/VI (0.87 [0.81-0.94]), as well as the risk of combined severe exacerbation or serious pneumonia versus UMEC/VI (0.83 [0.72-0.96]). FF/UMEC/VI reduced the rate of combined moderate/severe exacerbation or pneumonia (rate ratio, 0.78 [0.72-0.84]) and combined severe exacerbation or serious pneumonia (rate ratio, 0.76 [0.65-0.89]) versus UMEC/VI. Results were similar for radiographically confirmed pneumonia endpoints.Conclusions: Despite higher incidence of pneumonia in FF-containing arms, these composite exacerbation/pneumonia outcomes support a favorable benefit-risk profile of FF/UMEC/VI versus FF/VI and UMEC/VI in patients with symptomatic chronic obstructive pulmonary disease and a history of exacerbations.

BACKGROUND: In the Informing the Pathway of COPD Treatment (IMPACT) trial, single-inhaler triple-therapy fluticasone furoate (FF), umeclidinium (UMEC), and vilanterol (VI) reduced moderate/severe exacerbation rates vs FF/VI and UMEC/VI in patients with symptomatic COPD and a history of exacerbations, with a similar safety profile. RESEARCH QUESTION: Are trial outcomes with single-inhaler triple-therapy FF/UMEC/VI vs FF/VI and UMEC/VI affected by age in patients with symptomatic COPD and a history of exacerbations? STUDY DESIGN AND METHODS: IMPACT was a phase III, double-blind, 52-week trial. Patients ≥ 40 years of age with symptomatic COPD and ≥ 1 moderate/severe exacerbation in the previous year were randomly assigned 2:2:1 to FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg, or UMEC/VI 62.5/25 µg. End points assessed by age included annual rate of moderate/severe exacerbations, change from baseline (CFB) in trough FEV1, proportion of St. George's Respiratory Questionnaire (SGRQ) responders (≥ 4 units decrease from baseline in SGRQ total score), and safety. RESULTS: The intention-to-treat population comprised 10,355 patients; 4,724 (46%), 4,225 (41%), and 1,406 (14%) were ≤ 64, 65 to 74, and ≥ 75 years of age, respectively. FF/UMEC/VI reduced on-treatment moderate/severe exacerbation rates vs FF/VI (% reduction [95% CI]: ≤ 64 years, 8% [-1 to 16]; P = .070; 65-74 years, 22% [14-29]; P < .001; ≥ 75 years, 18% [3-31]; P = .021) and vs UMEC/VI (≤ 64 years, 16% [7-25]; P = .002; 65-74 years, 33% [25-41]; P < .001; ≥ 75 years, 24% [6-38]; P = .012), with greatest rate reduction seen in the 65 to 74 and ≥ 75 years subgroups. Post hoc analyses of CFB in trough FEV1 and proportion of SGRQ responders at week 52 were significantly greater with FF/UMEC/VI than with FF/VI or UMEC/VI in all subgroups. No new safety signals were identified. INTERPRETATION: FF/UMEC/VI reduced the rate of moderate/severe exacerbations and improved lung function and health status vs FF/VI and UMEC/VI irrespective of age for most end points, with a similar safety profile.

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.

INTRODUCTION: The phase 3 InforMing the PAthway of COPD (chronic obstructive pulmonary disease) Treatment (IMPACT) trial, single-inhaler therapy with fluticasone furoate (FF) 100 µg, umeclidinium (UMEC) 62.5 µg, and vilanterol (VI) 25 µg demonstrated a reduction in the rate of moderate or severe exacerbations compared with FF/VI or UMEC/VI in patients with symptomatic COPD at risk of exacerbations. This article reports additional evidence of improvements in symptoms and health-related quality of life (HRQoL) with FF/UMEC/VI compared with either FF/VI or UMEC/VI from the IMPACT study. METHODS: Patient-reported HRQoL assessments and symptom measures included as pre-specified IMPACT end points were the St George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), and Baseline Dyspnea Index (BDI) as the anchor for the Transitional Dyspnea Index (TDI) focal score (BDI/TDI) in a subset of patients enrolled at study sites in North America and Europe. Change from baseline was assessed at weeks 4, 28, and 52. RESULTS: The intent-to-treat population included 10,355 patients (TDI population: 5058 patients). Clinically meaningful improvements in SGRQ total score between baseline and week 52 favored FF/UMEC/VI over FF/VI (- 1.8 units, p < 0.001) and UMEC/VI (- 1.8 units, p < 0.001). Similar improvements in the CAT and TDI focal score were also observed with FF/UMEC/VI versus FF/VI or UMEC/VI. CONCLUSIONS: This study demonstrates that in patients with symptomatic COPD at risk of exacerbations, once-daily FF/UMEC/VI, compared with FF/VI or UMEC/VI, improves patient-perceived HRQoL and symptoms.

Purpose: The Informing the Pathway of COPD Treatment (IMPACT) study demonstrated that single-inhaler triple therapy fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) reduces moderate/severe exacerbation rates and improves lung function and health status versus FF/VI or UMEC/VI dual therapy in patients with symptomatic COPD and a history of exacerbations. This analysis evaluated the efficacy and safety of FF/UMEC/VI in patients enrolled in Japan. Patients and methods: IMPACT was a 52-week, randomized, double-blind, multicenter study comparing FF/UMEC/VI 100/62.5/25 µg with FF/VI 100/25 µg or UMEC/VI 62.5/25 µg in patients ≥40 years with symptomatic COPD and ≥1 moderate/severe exacerbation in the previous year. Endpoints included annual rate of on-treatment moderate/severe exacerbations (primary endpoint), time-to-first on-treatment moderate/severe exacerbation and change from baseline at Week 52 in trough FEV1, post-bronchodilator FEV1, St. George's Respiratory Questionnaire, and COPD Assessment Test score. Safety was also assessed. Results: The Japan subgroup accounted for only 4% (378/10,355) of the overall IMPACT intent-to-treat (ITT) population. In the Japan subgroup, FF/UMEC/VI reduced the annual rate of on-treatment moderate/severe exacerbations by 15% (95% CI: -20, 40) versus FF/VI (compared with 15% [10, 20] in the ITT) and 36% (95% CI: 6, 57) versus UMEC/VI (compared with 25% [19, 30] in the ITT). FF/UMEC/VI reduced moderate/severe exacerbation risk (time-to-first), improved lung function and health status at Week 52 versus both dual therapies. These results were in the same direction and of a generally similar magnitude to those seen in the overall ITT population. No new safety signals were identified in the Japan subgroup compared with the ITT population. Pneumonia incidence was higher with FF/UMEC/VI and FF/VI versus UMEC/VI. Conclusion: These results highlight the favorable benefit-risk profile of FF/UMEC/VI single-inhaler triple therapy compared with FF/VI or UMEC/VI dual therapy in patients in Japan with symptomatic COPD and ≥1 exacerbation in the prior year.

RATIONALE: Pneumonia risk with inhaled corticosteroid use in chronic obstructive pulmonary disease (COPD) has not been thoroughly assessed in patients with moderate airflow limitation. OBJECTIVES: To determine the incidence of pneumonia and risk factors in COPD patients with moderate airflow limitation who had, or were at high risk for cardiovascular disease. METHODS: In the Study to Understand Mortality and MorbidITy in COPD (SUMMIT), 16,590 subjects with moderate airflow limitation (50% ≤ FEV1 ≤ 70% predicted) and heightened cardiovascular risk were randomized double-blind 1:1:1:1 to inhaled once-daily vilanterol 25 µg (VI), fluticasone furoate 100 µg (FF), vilanterol 25 µg combined with 100 µg fluticasone furoate (FF/VI), or matched placebo. In a pre-specified analysis, we assessed investigator-reported adverse pneumonia events, and independently-adjudicated fatal events. MEASUREMENTS AND MAIN RESULTS: The safety population comprised 16,568 subjects who actually received study medication. There were 1017 pneumonia events reported from 842 subjects. For placebo, FF, VI and FF/VI, reported pneumonia incidence was 5%, 5%, 4% and 6%, respectively. When adjusted for time on treatment, event rates were similar in the placebo, FF and FF/VI containing arms (3.84, 4.24 and 3.95/100 treatment years, respectively) but lower in the VI group (2.77/100 treatment years). Risk factors for pneumonia risk included: greater degree of airflow limitation (i.e. FEV1 <60% predicted), prior exacerbation history, and BMI <25 kg/m2. CONCLUSIONS: In contrast to previous studies in patients with severe disease, increased pneumonia risk with inhaled corticosteroid use was not evident in COPD subjects with moderate airflow limitation and heightened cardiovascular risk.

PURPOSE: Dual therapy with bronchodilators of different pharmacological classes may produce greater lung function improvements than either drug alone. However, the relationship between a patient's response to monotherapy and response to dual bronchodilator therapy is currently unknown. We aimed to investigate whether dual therapy with umeclidinium/vilanterol provides additional benefit over umeclidinium or vilanterol monotherapy in patients with chronic obstructive pulmonary disease (COPD) identified as responsive (increase from baseline in forced expiratory volume in 1s [FEV1] of ≥ 12% and ≥ 200 mL, Day 1) or non-responsive to monotherapy. METHODS: In two randomised, double-blind, three-way complete-block, cross-over studies (DB2116132 n = 207; DB2116133 n = 182; intent-to-treat), all patients (moderate-to-very severe COPD) were randomised to 1 of 6 sequences and received once-daily umeclidinium 62.5 mcg, vilanterol 25 mcg, and umeclidinium/vilanterol 62.5/25 mcg (one treatment/14-day period; 10-14-day washout). Key endpoints were 0-6 h weighted mean FEV1 (Day 14) and trough FEV1 (Day 15). Adverse events, vital signs and COPD exacerbations were assessed. Pooled data are presented. RESULTS: Umeclidinium/vilanterol significantly (p ≤ 0.001, unless stated otherwise) increased 0-6 h weighted mean FEV1 versus umeclidinium in umeclidinium-responders (+114 mL), versus vilanterol in vilanterol-responders (+92 mL) and versus umeclidinium (+70 mL) and vilanterol (+62 mL) in non-responders. Improvements in trough FEV1 occurred with umeclidinium/vilanterol versus umeclidinium in umeclidinium-responders (+77 mL), versus vilanterol in vilanterol-responders (+86 mL), and versus umeclidinium (+42 mL [p = 0.020]) and vilanterol (+58 mL) in non-responders. All treatments were well tolerated. CONCLUSIONS: Once-daily umeclidinium/vilanterol significantly improved lung function in patients with COPD, with quantitatively greater improvements in patients identified as responders to umeclidinium and vilanterol monotherapy than non-responders.

BACKGROUND AND OBJECTIVES: A fixed-dose combination of the bronchodilators umeclidinium and vilanterol is in development for the long-term, once-daily treatment of chronic obstructive pulmonary disease (COPD). We characterized the pharmacokinetics of umeclidinium and vilanterol in ≈1,635 patients with COPD, evaluating the impact of patient demographics and baseline characteristics on umeclidinium and vilanterol exposure. METHODS: Plasma concentrations of umeclidinium and vilanterol were evaluated in patients enrolled in two phase III, randomized, double-blind, parallel-group, placebo-controlled trials using inhaled umeclidinium/vilanterol combination therapy and inhaled umeclidinium and vilanterol monotherapies as treatments. Population-pharmacokinetic models were developed using non-linear mixed-effects analyses, performed using NONMEM(®) software. A likelihood-based approach was used to characterize the data below limit of quantification. Umeclidinium and vilanterol exposures at clinical doses were simulated based on the population model. RESULTS: For the umeclidinium and vilanterol population-pharmacokinetic analyses, 1,635 and 1,637 patients provided 8,498 and 8,405 observations, respectively. Umeclidinium and vilanterol pharmacokinetics were best described by a two-compartment model with first-order absorption. For umeclidinium, bodyweight, age, and creatinine clearance (CLCR) were statistically significant covariates for apparent inhaled clearance (CL/F); bodyweight was a statistically significant covariate for volume of distribution of central compartment (V 2/F).The population parameter estimates namely CL/F and V 2/F for umeclidinium were 218 L/h and 1,160 L and 40.9 L/h and 268 L for vilanterol. For vilanterol, bodyweight and age were statistically significant covariates for CL/F. The effect of covariates on umeclidinium and vilanterol systemic exposure was marginal. The population model indicates that a 10 % increase in bodyweight will result in a 2 % increase in CL/F for umeclidinium and vilanterol and 6 % increase in umeclidinium V 2/F. A 10 % increase in age will provide a 7 and 4 % decrease in umeclidinium and vilanterol CL/F, respectively. A 10 % decrease in CLCR will result in a 3 % decrease in umeclidinium CL/F. Umeclidinium and vilanterol population-pharmacokinetic model-based systemic exposure predictions showed no pharmacokinetic interactions between umeclidinium and vilanterol when administered in combination. CONCLUSIONS: There were no apparent pharmacokinetic interactions when umeclidinium and vilanterol were co-administered in patients with COPD. The effects of patient demographics, including age, bodyweight, and CLCR, on umeclidinium or vilanterol systemic exposure were minimal, and therefore no dose adjustments are necessary.

BACKGROUND: Combination long-acting bronchodilator therapy may be more effective than long-acting bronchodilator monotherapy in chronic obstructive pulmonary disease (COPD). OBJECTIVES: To compare the efficacy and safety of once-daily umeclidinium/vilanterol (UMEC/VI) 125/25 mcg with placebo and UMEC or VI monotherapy in COPD. METHODS: This was a double-blind, placebo-controlled, parallel-group study. A total of 1493 patients were randomized (3:3:3:2) to 24 weeks of treatment with UMEC/VI 125/25 mcg, UMEC 125 mcg, VI 25 mcg, or placebo once-daily via dry powder inhaler. RESULTS: Primary efficacy endpoint was trough forced expiratory volume in one second (FEV1) on Day 169 (23-24 h post-dose). Additional lung-function, symptomatic and health-related quality of life endpoints were also assessed. Safety evaluations included: adverse events, vital signs, electrocardiography and clinical laboratory measurements. All active treatments significantly improved trough FEV1 vs placebo (0.124-0.238 L, all p<0.001). Improvements with UMEC/VI 125/25 mcg were significantly greater than for UMEC 125 mcg or VI 25 mcg (0.079 L and 0.114 L; both p≤0.001). Improvements for UMEC/VI 125/25 mcg vs placebo were observed for the transition dyspnea index (1.0 unit; p<0.001), rescue albuterol use at Weeks 1-24 (-1.5 puffs/day) and St. George's Respiratory Questionnaire (-3.60 units, p<0.001). No safety signals were observed. CONCLUSIONS: Once-daily UMEC/VI 125/25 mcg was well tolerated and provided greater improvements in lung function, health status, and dyspnea scores compared with monotherapy components and placebo over 24 weeks. This study supports the use of UMEC/VI 125/25 mcg for the maintenance treatment of COPD. CLINICAL TRIAL REGISTRATION: protocol number: DB2113361; ClinicalTrials.gov identifier: NCT01313637.

BACKGROUND: Once-daily combination treatment is an attractive maintenance therapy for COPD. However, the dose of inhaled corticosteroid to use in a once-daily combination is unknown. We compared two strengths of fluticasone furoate (FF) plus vilanterol (VI), the same strengths of the individual components, and placebo. METHODS: Multicentre, randomised, 24-week, double-blind, placebo-controlled, parallel-group study in stable, moderate-to-severe COPD subjects (N = 1224). Subjects were randomised to FF/VI (200/25 µg; 100/25 µg), FF (200 µg; 100 µg), VI 25 µg, or placebo, once daily in the morning. Co-primary efficacy endpoints; 0-4 h weighted mean (wm) FEV(1) on day 168, and change from baseline in trough (23-24 h post-dose) FEV(1) on day 169. The primary safety objective was adverse events (AEs). RESULTS: There was a statistically significant (p < 0.001) increase in wm FEV(1) (209 ml) and trough FEV(1) (131 ml) for FF/VI 200/25 µg vs. placebo; similar changes were seen for FF/VI 100/25 µg vs. placebo. Whereas the difference between FF/VI 200/25 µg and VI 25 µg in change from baseline trough FEV(1) (32 ml) was not statistically significant (p = 0.224), the difference between FF/VI 200/25 µg and FF 200 µg for wm FEV(1) (168 ml) was significantly different (p < 0.001). VI 25 µg significantly improved wm and trough FEV(1) vs. placebo (185 ml and 100 ml, [corrected] respectively). No increase was seen in on-treatment AEs or serious AEs (SAEs), with active therapy vs. placebo. CONCLUSIONS: FF/VI provides rapid and significant sustained improvement in FEV(1) in subjects with moderate-to-severe COPD, which was not influenced by the dose of FF. These data suggest that FF/VI may offer clinical efficacy in COPD and warrants additional study. GSK study number: HZC112207. ClinicalTrials.gov: NCT01054885.
