Efficacy and safety of once-daily single-inhaler triple therapy (FF/UMEC/VI) versus FF/VI in patients with inadequately controlled asthma (CAPTAIN): a double-blind, randomised, phase 3A trial.
Despite inhaled corticosteroid plus long-acting β2-agonist (ICS/LABA) therapy, 30-50% of patients with moderate or severe asthma remain inadequately controlled. We investigated the safety and efficacy of single-inhaler fluticasone furoate plus umeclidinium plus vilanterol (FF/UMEC/VI) compared with FF/VI.
In this double-blind, randomised, parallel-group, phase 3A study (Clinical Study in Asthma Patients Receiving Triple Therapy in a Single Inhaler [CAPTAIN]), participants were recruited from 416 hospitals and primary care centres across 15 countries. Participants were eligible if they were aged 18 years or older, with inadequately controlled asthma (Asthma Control Questionnaire [ACQ]-6 score of ≥1·5) despite ICS/LABA, a documented health-care contact or a documented temporary change in asthma therapy for treatment of acute asthma symptoms in the year before screening, pre-bronchodilator FEV1 between 30% and less than 85% of predicted normal value, and reversibility (defined as an increase in FEV1 of ≥12% and ≥200 mL in the 20-60 min after four inhalations of albuterol or salbutamol) at screening. Participants were randomly assigned (1:1:1:1:1:1), via central based randomisation stratified by pre-study ICS dose at study entry, to once-daily FF/VI (100/25 μg or 200/25 μg) or FF/UMEC/VI (100/31·25/25 μg, 100/62·5/25 μg, 200/31·25/25 μg, or 200/62·5/25 μg) administered via Ellipta dry powder inhaler (Glaxo Operations UK, Hertfordshire, UK). Patients, investigators, and the funder were masked to treatment allocation. Endpoints assessed in the intention-to-treat population were change from baseline in clinic trough FEV1 at week 24 (primary) and annualised moderate and/or severe asthma exacerbation rate (key secondary). Other secondary endpoints were change from baseline in clinic FEV1 at 3 h post-dose, St George's Respiratory Questionnaire (SGRQ) total score, and ACQ-7 total score, all at week 24. Change from baseline in Evaluating Respiratory Symptoms in Asthma total score at weeks 21-24 was also a secondary endpoint but is not reported here. Exploratory analyses of biomarkers of type 2 airway inflammation on treatment response were also done. This study is registered with ClinicalTrials.gov, NCT02924688, and is now complete.
Between Dec 16, 2016, and Aug 31, 2018, 5185 patients were screened and 2439 were recruited and randomly assigned to FF/VI (100/25 μg n=407; 200/25 μg n=406) or FF/UMEC/VI (100/31·25/25 μg n=405; 100/62·5/25 μg n=406; 200/31·25/25 μg n=404; 200/62·5/25 μg n=408), with three patients randomly assigned in error and not included in analyses. In the intention-to-treat population, 922 (38%) patients were men, the mean age was 53·2 years (SD 13·1) and body-mass index was 29·4 (6·6). Baseline demographics were generally similar across all treatment groups. The least squares mean improvement in FEV1 change from baseline for FF/UMEC/VI 100/62·5/25 μg versus FF/VI 100/25 μg was 110 mL (95% CI 66-153; p<0·0001) and for 200/62·5/25 μg versus 200/25 μg was 92 mL (49-135; p<0·0001). Adding UMEC 31·25 μg to FF/VI produced similar improvements (FF/UMEC/VI 100/31·25/25 μg vs FF/VI 100/25 μg: 96 mL [52-139; p<0·0001]; and 200/31·25/25 μg vs 200/25 μg: 82 mL [39-125; p=0·0002]). These results were supported by the analysis of clinic FEV1 at 3 h post-dose. Non-significant reductions in moderate and/or severe exacerbation rates were observed for FF/UMEC 62·5 μg/VI versus FF/VI (pooled analysis), with rates lower in FF 200 μg-containing versus FF 100 μg-containing treatment groups. All pooled treatment groups demonstrated mean improvements (decreases) in SGRQ total score at week 24 compared with baseline in excess of the minimal clinically important difference of 4 points; however, there were no differences between treatment groups. For mean change from baseline to week 24 in asthma control questionnaire-7 score, improvements (decreases) exceeding the minimal clinically important difference of 0·5 points were observed in all pooled treatment groups. Adding UMEC to FF/VI resulted in small, dose-related improvements compared with FF/VI (pooled analysis: FF/UMEC 31·25 μg/VI versus FF/VI, -0·06 (95% CI -0·12 to 0·01; p=0·094) FF/UMEC 62·5 μg/VI versus FF/VI, -0·09 (-0·16 to -0·02, p=0·0084). By contrast with adding UMEC, the effects of higher dose FF on clinic trough FEV1 and annualised moderate and/or severe exacerbation rate were increased in patients with higher baseline blood eosinophil count and exhaled nitric oxide. Occurrence of adverse events was similar across treatment groups (patients with at least one event ranged from 210 [52%] to 258 [63%]), with the most commonly reported adverse events being nasopharyngitis (51 [13%]-63 [15%]), headache (19 [5%]-36 [9%]), and upper respiratory tract infection (13 [3%]-24 [6%]). The incidence of serious adverse events was similar across all groups (range 18 [4%]-25 [6%)). Three deaths occurred, of which one was considered to be related to study drug (pulmonary embolism in a patient in the FF/UMEC/VI 100/31·25/25 μg group).
In patients with uncontrolled moderate or severe asthma on ICS/LABA, adding UMEC improved lung function but did not lead to a significant reduction in moderate and/or severe exacerbations. For such patients, single-inhaler FF/UMEC/VI is an effective treatment option with a favourable risk-benefit profile. Higher dose FF primarily reduced the rate of exacerbations, particularly in patients with raised biomarkers of type 2 airway inflammation. Further confirmatory studies into the differentiating effect of type 2 inflammatory biomarkers on treatment outcomes in asthma are required to build on these exploratory findings and further guide clinical practice.

Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI) Triple Therapy Compared with Other Therapies for the Treatment of COPD: A Network Meta-Analysis.
Randomized controlled trials (RCTs) comparing triple therapies (inhaled corticosteroid [ICS], long-acting β2-agonist [LABA], and long-acting muscarinic antagonist [LAMA]) for the treatment of chronic obstructive pulmonary disease (COPD) are limited. This network meta-analysis (NMA) investigated the comparative efficacy of single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus any triple (ICS/LABA/LAMA) combinations and dual therapies in patients with COPD.
This NMA was conducted on the basis of a systematic literature review (SLR), which identified RCTs in adults aged at least 40 years with COPD. The RCTs compared different ICS/LABA/LAMA combinations or an ICS/LABA/LAMA combination with any dual therapy (ICS/LABA or LAMA/LABA). Outcomes of interest included forced expiratory volume in 1 s (FEV1), annualized rate of combined moderate and severe exacerbations, St George's Respiratory Questionnaire (SGRQ) total score and SGRQ responders, transition dyspnea index focal score, and rescue medication use (RMU). Analyses were conducted at 24 weeks (primary endpoint), and 12 and 52 weeks (if feasible).
The NMA was informed by five trials reporting FEV1 at 24 weeks. FF/UMEC/VI was statistically significantly more effective at increasing trough FEV1 (based on change from baseline) than all triple comparators in the network apart from UMEC + FF/VI. The NMA was informed by 17 trials reporting moderate or severe exacerbation endpoints. FF/UMEC/VI demonstrated statistically significant improvements in annualized rate of combined moderate or severe exacerbations versus single-inhaler budesonide/glycopyrronium bromide/formoterol fumarate (BUD/GLY/FOR). At 24 weeks, the NMA was informed by five trials. FF/UMEC/VI showed statistically significant improvements in annualized rate of combined moderate or severe exacerbations versus UMEC + FF/VI and BUD/GLY/FOR. FF/UMEC/VI also demonstrated improvements in mean SGRQ score versus other triple therapy comparators at 24 weeks, and a significant reduction in RMU compared with BUD/GLY/FOR (160/18/9.6).
The findings of this NMA suggest favorable efficacy with single-inhaler triple therapy comprising FF/UMEC/VI. Further analysis is required as additional evidence becomes available.

The IMPACT Study - Single Inhaler Triple Therapy (FF/UMEC/VI) Versus FF/VI And UMEC/VI In Patients With COPD: Efficacy And Safety In A Japanese Population.
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.
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.
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.
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.
