Glycopyrronium once-daily significantly improves lung function and health status when combined with salmeterol/fluticasone in patients with COPD: the GLISTEN study, a randomised controlled trial

Outcomes Following Initiation of Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol versus Multiple-Inhaler Triple Therapy Among Medicare Advantage with Part D Beneficiaries and Those Commercially Enrolled for Health Care Insurance in the United States

Purpose

Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US.

Methods

Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators.

Results

In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant.

Conclusion

FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

The Management of Acute Exacerbations in COPD: A Retrospective Observational Study and Clinical Audit

(1) Background: Acute exacerbations of chronic obstructive pulmonary disease (COPD) are not only associated with increased patient morbidity and mortality, but with extensive healthcare costs. Thus, adequate clinical management is crucial. The aim of this project was to evaluate the management of acute COPD exacerbations in a public teaching hospital in Switzerland. (2) Methods: We retrospectively analyzed clinical routine data of patients presenting with an acute exacerbation of COPD at the emergency department of a Swiss hospital between January 2019 and February 2020. Management was evaluated against recommendations from the GOLD 2019 report and previous audits. (3) Results: The data of 184 patients (mean age 73.5 years, range 41-95 years, 53% male) with 226 visits were included. While the documentation of GOLD stage (I-IV) and smoking status was consistent (81.0% and 91.6%), GOLD risk category (A-D) was only documented in 36% of the cases. Patients' respiratory rate upon presentation was measured in 73%, and blood gas analysis was performed in 70%. A total of 94% of the patients received a chest imaging; spirometry was performed in 10%. Initial symptomatic therapy with short acting bronchodilators was applied in 56%. Systemic steroid treatment was installed in 86%. Antibiotics were given in 56%, but in one fourth the indication was not clear. Non-invasive ventilation was applied in 25% of the indicated cases. Smoking cessation was recommended to 26% of the current smokers and referral to pulmonary rehabilitation was given in 16%. (4) Conclusion: GOLD recommendations were not comprehensively implemented, especially with regard to the assessment of severity, initial symptomatic therapy, and non-invasive ventilation. These results show the importance of the frequent revision of routine practice and may help to create awareness among practitioners and ultimately improve the quality of COPD management.

Real-World Experience of Treating Chronic Obstructive Pulmonary Disease with Triple Therapy

Background

Double-blind randomized controlled trials have compared patients with chronic obstructive pulmonary disease (COPD) taking triple therapy, which can improve lung function, dyspnea, and quality of life and reduce acute exacerbation and mortality, with those taking long-acting muscarinic antagonist/long-acting β2-agonist; however, the real-word treatment scenario may be different from that of a strict and well-designed study. The aim of our study was to assess long-term outcomes among patients with COPD who received triple therapy in real-world practice.

Methods

Data from Taiwan's National Health Insurance Research Database (NHIRD) from 2005 and 2016 were used to identify COPD patients who were over 40 years of age with diagnosis codes 490-492, 496 (ICD-9-CM) or J41-44 (ICD-10-CM). After matching for age, sex, and COPD exacerbations, COPD patients who did and did not receive triple therapy were enrolled in this study. Cox proportional regression was used to estimate the mortality risk between smoking status and COPD patients with and without triple therapy.

Results

A total of 19,358 patients with COPD who did or did not receive triple therapy were enrolled in this study. The prevalence rates of some comorbidities were higher among patients with COPD who received triple therapy than among those who did not receive triple therapy. These comorbidities included lung cancer, thoracic malignancies, bronchiectasis, and heart failure. The risk of mortality was higher among patients who received triple therapy than among those who did not receive triple therapy after matching for age, sex, and COPD exacerbations, with a crude hazard ratio, fully adjusted model hazard ratio and stepwise approach reduced hazard ratio of 1.568 (95% CI, 1.500-1.639), 1.675 (95% CI, 1.596-1.757), and 1.677 (95% CI, 1.599-1.76), respectively.

Conclusion

Over 5 years of observation, patients with COPD who received triple therapy did not show a survival benefit compared with those who did not receive triple therapy in a real-world scenario.

Combination therapy with long-acting bronchodilators and the risk of major adverse cardiovascular events in patients with COPD: a systematic review and meta-analysis

INTRODUCTION

Accumulated high-quality data from randomised controlled trials (RCTs) indicate that long-acting muscarinic antagonist (LAMA)/long-acting β2 agonist (LABA) combination therapy significantly improves clinical symptoms and health status in patients with chronic obstructive pulmonary disease (COPD) and reduces exacerbation risk. However, there is a growing concern that LAMA/LABA therapy may increase the risk of cardiovascular disease in patients with COPD. The aim of this paper is to determine whether the use of LAMA/LABA combination therapy modifies the risk of cardiovascular disease in patients with COPD.

METHODS

Two reviewers independently searched Embase, PubMed and Cochrane Library to identify relevant RCTs of LAMA/LABA or LABA/LAMA/inhaled corticosteroids (ICS) for the management of patients with COPD that reported on cardiovascular end-points. The primary outcome was major adverse cardiovascular events (MACE), which was a composite of cardiovascular death, myocardial infarction or stroke.

RESULTS

A total of 51 RCTs enrolling 91 021 subjects were analysed. Both dual LAMA/LABA (1.6% versus 1.3%; relative risk 1.42, 95% CI 1.11-1.81) and triple therapy (1.6% versus 1.4%; relative risk 1.29, 95% CI 1.03-1.61) significantly increased the risk of MACE compared with ICS/LABA. The excess risk was most evident in RCTs in which the average underlying baseline risk for MACE was >1% per year. Compared with LAMA only, LABA only or placebo, dual LAMA/LABA therapy did not significantly increase the risk of MACE, though these comparisons may have lacked sufficient statistical power.

CONCLUSION

Compared with ICS/LABA, dual LAMA/LABA or triple therapy increases cardiovascular risk in patients with COPD. This should be considered in the context of the incremental benefits of these therapies for symptoms and exacerbation rates in patients with COPD, especially in those with a MACE risk of >1% per year.

Different inhaled corticosteroid doses in triple therapy for chronic obstructive pulmonary disease: systematic review and Bayesian network meta-analysis

A systematic review and Bayesian network meta-analysis is necessary to evaluate the efficacy and safety of triple therapy with different doses of inhaled corticosteroids (ICS) in stable chronic obstructive pulmonary disease (COPD). We selected 26 parallel randomized controlled trials (41,366 patients) comparing triple therapy with ICS/long-acting beta-agonist (LABA), LABA/long-acting muscarinic antagonist (LAMA), and LAMA in patients with stable COPD for ≥ 12 weeks from PubMed, EMBASE, the Cochrane Library, and clinical trial registries (search from inception to June 30, 2022). Triple therapy with high dose (HD)-ICS exhibited a lower risk of total exacerbation in pre-specified subgroups treated for ≥ 48 weeks than that with low dose (LD)-ICS (odds ratio [OR] = 0.66, 95% credible interval [CrI] = 0.52–0.94, low certainty of evidence) or medium dose (MD)-ICS (OR = 0.66, 95% CrI = 0.51–0.94, low certainty of evidence). Triple therapy with HD-ICS exhibited a lower risk of moderate-to-severe exacerbation in pre-specified subgroups with forced expiratory volume in 1 s < 65% (OR = 0.6, 95% CrI = 0.37–0.98, low certainty of evidence) or previous exacerbation history (OR = 0.6, 95% CrI = 0.36–0.999, very low certainty of evidence) than triple therapy with MD-ICS. Triple therapy with HD-ICS may reduce acute exacerbation in patients with COPD treated with other drug classes including triple therapy with LD- or MD-ICS or dual therapies.

Why small particle fixed dose triple therapy? An excursus from COPD pathology to pharmacological treatment evolution

Although bronchodilators are the cornerstone in chronic obstructive pulmonary disease (COPD) therapy, the treatment with a single-agent bronchodilator may not provide adequate symptoms control in COPD. The combination of drugs with different mechanisms of action may be more effective in inducing bronchodilation and preventing exacerbations, with a lower risk of side-effects in comparison with the increase of the dose of a single molecule. Several studies comparing the triple therapy with the association of long-acting ß2 agonist (LABA)/inhaled corticosteroid (ICS) or long-acting muscarinic antagonist (LAMA)/LABA reported improvement of lung function and quality of life. A significant reduction in moderate/severe exacerbations has been observed with a fixed triple combination of beclometasone dipropionate (BDP), formoterol fumarate (FF) and glycopyrronium (G) in a single inhaler. The TRILOGY, TRINITY and TRIBUTE studies have provided confirming evidence for a clinical benefit of triple therapy over ICS/LABA combination treatment, LAMA monotherapy and LABA/LAMA combination, with prevention of exacerbations being a key finding. A pooled post hoc analysis of the published clinical studies involving BDP/FF/G fixed combination demonstrated a reduction in fatal events in patients treated with ICS-containing medications, with a trend of statistical significance [hazard ratio = 0.72, 95% confidence interval (CI) 0.50-1.02, p = 0.066], that becomes significant if we consider reduction in fatal events for non-respiratory reasons (hazard ratio = 0.65, 95% CI 0.43-0.97, p = 0.037). In conclusion, a fixed combination of more drugs in a single inhaler can improve long-term adherence to the therapy, reducing the risk of exacerbations and hospital resources utilization. The twice a day administration may provide a better coverage of night, particularly in COPD patients who are highly symptomatic. The inhaled extrafine formulation that allows drug deposition in both large and small - peripheral - airways, is the value added.

Efficacy and safety of revefenacin for nebulization in patients with chronic obstructive pulmonary disease taking concomitant ICS/LABA or LABA: subgroup analysis from phase III trials

Background:

Combinations of a long-acting muscarinic receptor antagonist (LAMA), long-acting β-agonist (LABA), and inhaled corticosteroid (ICS) are used for patients with persistent chronic obstructive pulmonary disease (COPD) exacerbations on bronchodilator monotherapy. In this prespecified subgroup analysis, we assessed the efficacy and safety of the LAMA revefenacin in patients with COPD taking concomitant LABA, including ICS/LABA (LABA subgroup).

Methods:

Efficacy data were obtained from two 12-week, replicate, placebo-controlled trials and safety data were pooled from the 12-week and a 52-week tiotropium-controlled trial. Patients received revefenacin 175 µg or placebo in the 12-week or tiotropium 18 µg in the 52-week studies. The efficacy endpoint was least squares (LS) mean change from baseline in trough forced expiratory volume in 1 second (FEV₁). Clinical health outcomes were assessed using the St. George’s Respiratory Questionnaire (SGRQ).

Results:

Revefenacin produced similar improvements from baseline in trough FEV₁ in the non-LABA and LABA subgroups [placebo-adjusted LS mean change (95% confidence interval) in day 85 trough FEV₁, 150.9 (110.3−191.6) ml and 139.2 (82.9−195.5) ml; p < 0.0001 versus placebo]. Similar improvements were observed in SGRQ scores in the non-LABA and LABA subgroups [−3.3 (−5.4 to −1.2) and −3.4 (−6.3 to −0.6)]. Improvements in lung function and health outcomes were observed regardless of airflow obstruction severity. Revefenacin was well tolerated with more adverse events reported in the LABA than the non-LABA subgroup.

Conclusions:

Once daily revefenacin for nebulization can be an effective and well-tolerated treatment for patients who require concomitant use of LABA with or without ICS.

Comparisons of Efficacy and Safety between Triple (Inhaled Corticosteroid/Long-Acting Muscarinic Antagonist/Long-Acting Beta-Agonist) Therapies in Chronic Obstructive Pulmonary Disease: Systematic Review and Bayesian Network Meta-Analysis

BACKGROUND

Various combinations of inhaled corticosteroid (ICS), long-acting muscarinic antagonist (LAMA), and long-acting beta-agonist (LABA) have been used as triple therapy for stable chronic obstructive pulmonary disease (COPD).

OBJECTIVE

Our study was conducted to answer whether there were significant differences among various combinations in efficacy, for reducing exacerbation or mortality, and in safety, for increasing cardiovascular events or pneumonia.

METHOD

We searched parallel-group randomized controlled trials (RCTs) comparing ICS/LAMA/LABA with other inhaled drugs in patients with stable COPD for at least 12 weeks in PubMed, EMBASE, the Cochrane Library, and clinical trial registries from inception to December 31, 2019. We conducted a network meta-analysis with Bayesian statistics using a random-effects model with heterogeneous variance structure (PROSPERO, CRD42019126757).

RESULTS

Nine different combinations of ICS/LAMA/LABA were identified in 21 RCTs containing 29,892 patients with moderate to very severe COPD. We could not find any significant evidence suggesting a better treatment for reducing total exacerbations or all-cause mortality among ICS/LAMA/LABA combinations. There were also no significant differences in moderate to severe exacerbation, COPD-related mortality, or cardiovascular disease-related mortality among ICS/LAMA/LABA combinations, and the risk of major adverse cardiovascular events was not different. A significantly lower risk of pneumonia was found in fluticasone propionate (FP)/glycopyrrolate/salmeterol (SAL) than FP/tiotropium/SAL {median odds ratio [OR] (95% credible interval [CrI]) = 0 [0-0.72]} and FP/umeclidinium/SAL {median OR (95% Crl) = 0 [0-0.97]}.

CONCLUSION

There were no significant differences in clinical outcomes, including acute exacerbation and all-cause mortality among various ICS/LAMA/LABA combinations in patients with moderate to very severe COPD.

Treatment Preferences of Patients with Chronic Obstructive Pulmonary Disease: Results from Qualitative Interviews and Focus Groups in the United Kingdom, United States, and Germany

BACKGROUND

A wide range of therapeutic regimens, including single-inhaler triple therapies (SITTs), are now available for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Thus, an improved understanding of patient preferences may be valuable to inform physician prescribing decisions. This study was performed to assess the factors considered by patients when making decisions about their COPD treatments using qualitative techniques.

METHODS

In the United Kingdom, United States and Germany, individual qualitative interviews (n=10 per country) and focus groups (1 per country; [United Kingdom, n=4; United States, n=6; Germany, n=6 participants]) were conducted. Interviews and focus groups were semi‑structured, lasting approximately 60 minutes, and focused on treatment preferences. Data were analyzed according to emerging themes identified from the interviews; qualitative thematic analysis of the data was performed using specialist software.

RESULTS

In interviews and focus groups, efficacy, ease of use, and lower frequency of use were favored attributes for current treatment, while side effects, medication taste, and more complex administration techniques were key dislikes. In interviews, most participants would consider a switch in medication, mainly for improved efficacy, but also to reduce medication frequency or following physician advice. Overall, efficacy and ease of use were the 2 most important attributes reported in interviews in all 3 countries.

CONCLUSION

Patients with COPD have preferences for certain attributes of medication, highlighting the multi-faceted nature of treatment effectiveness and the importance of the delivery device.These results were subsequently used to inform the design of a discrete choice experiment.

Effect of Triple Therapy with Budesonide-Formoterol-Tiotropium Versus Placebo-Tiotropium on Sleep Quality in Patients with Chronic Obstructive Pulmonary Disease

Background

Factors responsible for poor sleep quality in patients with chronic obstructive pulmonary disease (COPD) includes the effects of medications. This study evaluates the effect of the inhaled triple therapy of budesonide-formoterol-tiotropium versus placebo-tiotropium on sleep quality in COPD patients.

Methods

Twenty-three patients (11 [48%] males; age 55 [51-60, 48--5] years; body mass index [BMI] 25 [22-30, 18-40] kg/m²; forced expiratory volume in 1 second [FEV₁]1.10 [0.80 -1.90, 0.60-2.80] L, 42 [31-62, 24-75] % predicted) were studied. Ten patients were randomized to budesonide-formoterol-tiotropium and 13 patients to placebo-tiotropium. At baseline and after 28 days, patients completed spirometry, polysomnography, an Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), COPD-specific St George's Respiratory Questionnaire (SGRQ-C) and short form 36 (SF 36).

Results

After 28 days, there was a significant 29% increase in the bedtime FEV₁ in the budesonide-formoterol-tiotropium group (from 0.75 [0.55-1.30, 0.50-2.40] L to 1.00 [0.75-1.55, 0.50-3.00] L, p=0.031), with no change in the placebo-tiotropium group (from 1.20 [0.80-1.50, 0.60-1.90] L to 1.15 [0.75-1.55, 0.50-1.80] L, p=0.91). No significant change was found post treatment in sleep efficiency or total sleep time in both the budesonide-formoterol-tiotropium group (from 78 [72-92, 62-98]% to 88 [77-92, 40-98]%, p=0.70 and 290 [268-358, 252-382] min to 342 [303-358, 157-372] min, p=0.77, respectively) and the placebo-tiotropium group (from 82 [75-88, 46-93]% to 84 [77-87, 62-94]%, p=0.96 and 320 [292-350, 180-378] min to 339 [303-349, 241-366] min, p=0.79, respectively). While there was no significant change in the arousal index in the budesonide-formoterol-tiotropium group (9 [5-16, 0-48] arousals/hour to 14 [9-17, 2-36] arousals/hour, p=0.43), a significant increase was seen in the placebo-tiotropium group (11 [4-13, 3--2] arousals/hour to 17 [11-21, 2-33] arousals/hour, p=0.027). Similarly, there was no change in the ESS in the budesonide-formoterol-tiotropium group (6 [3-8, 0-11] to 6 [5-8, 0-1]), p=0.44), but a marginally significant increase in the placebo-tiotropium group (8 [5-12, 2-18] to 10 [7-13, 5-18], p=0.07), with a significant difference in the ESS 28 days post treatment between the 2 groups (6 [5-8, 0-11] versus 10 [7-13, 5-18], p=0.043). There was no significant change in nocturnal oxygenation, sleep architecture, PSQI, SGRQ-C, or SF 36 in both groups.

Conclusion

In patients with COPD, inhaled triple therapy with budesonide-formoterol-tiotropium as compared to placebo-tiotropium improves pulmonary function while preserving sleep quality and architecture.

Real-Life Clinical and Functional Effects of Fluticasone Furoate/Umeclidinium/Vilanterol-Combined Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease

BACKGROUND

Triple therapy consisting of a drug association including an inhaled corticosteroid, a long-acting muscarinic receptor antagonist and a long-acting β2-adrenergic agonist, delivered via a single device, can be a valuable treatment for chronic obstructive pulmonary disease (COPD) patients experiencing frequent disease exacerbations.

OBJECTIVES

The aim of this real-life, single-center, observational study was to evaluate, in 44 COPD patients with recurrent exacerbations, the effects of the triple inhaled therapy combining fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI).

METHODS

Within such a therapeutic context, several clinical and lung functional parameters were considered at baseline and after 24 weeks of treatment with combined inhaled triple therapy.

RESULTS

With respect to baseline, after 24 weeks of treatment with FF/UMEC/VI, significant changes were recorded with regard to Modified British Medical Research Council (p < 0.0001) and COPD Assessment Test (p < 0.0001) scores, COPD exacerbations (p < 0.001), forced expiratory volume in the first second (p < 0.001), residual volume (p < 0.01), forced mid-expiratory flow between 25 and 75% of FVC (p < 0.0001), inspiratory capacity (p < 0.01), forced vital capacity (p < 0.05), and peak expiratory flow (p < 0.0001). Moreover, in a subgroup of 28 patients, a significant increase of diffusion lung capacity (p < 0.01) was also detected.

CONCLUSIONS

In conclusion, our real-life results suggest that triple inhaled therapy with FF/UMEC/VI, when given to COPD patients with frequent exacerbations, is able to positively impact on dyspnea and global health status as well as to significantly decrease COPD exacerbations and improve airflow limitation and lung hyperinflation.

Triple therapy for COPD: a crude analysis from a systematic review of the evidence

We systematically reviewed the current knowledge on fixed-dose triple therapies for the treatment of chronic obstructive pulmonary disease (COPD), with a specific focus on its efficacy versus single bronchodilation, double fixed dose combinations, and open triple therapies. Articles were retrieved from PubMed, Embase, and Scopus up to 3 August 2018. We selected articles with randomized controlled or crossover design conducted in patients with COPD and published as full-length articles or scientific letters, evaluating triple therapy combinations in a single or different inhaler, and with efficacy data versus monocomponents, double combinations, or open triple therapies. Our systematic search reported 108 articles, of which 24 trials were finally selected for the analysis. A total of 7 studies with fixed dose triple therapy combinations, and 17 studies with open triple therapies combinations. Triple therapy showed improvements in lung function [trough forced expiratory volume (FEV₁₎ ranging from not significant (NS) to 147 ml], health status using the St. George’s Respiratory Questionnaire [(SGRQ) from NS to 8.8 points], and exacerbations [risk ratio (RR) from NS to 0.59 for all exacerbations] versus single or double therapies with a variability in the response, depending the specific combination, and the comparison group. The proportion of adverse effects was similar between study groups, the exception being the increase in pneumonia for some inhaled corticosteroid (ICS) containing groups.

Once-daily single-inhaler versus twice-daily multiple-inhaler triple therapy in patients with COPD: lung function and health status results from two replicate randomized controlled trials

Background

The comparative efficacy of inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β₂-agonist (ICS/LAMA/LABA) triple therapy administered via single or multiple inhalers in patients with chronic obstructive pulmonary disease (COPD) has not been evaluated comprehensively. We conducted two replicate trials comparing single- with multiple-inhaler ICS/LAMA/LABA combination in COPD.

Methods

207608 and 207609 were Phase IV, 12-week, randomized, double-blind, triple-dummy non-inferiority trials comparing once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 μg via Ellipta inhaler, with twice-daily budesonide/formoterol (BUD/FOR) 400/12 μg via metered-dose inhaler plus once-daily tiotropium (TIO) 18 μg via HandiHaler. Patients had symptomatic COPD and forced expiratory volume in 1 s (FEV₁) < 50% predicted, or FEV₁ < 80% predicted and ≥ 2 moderate or 1 severe exacerbations in the prior year. The primary endpoint in both trials was weighted mean change from baseline (wmCFB) in 0–24-h FEV₁ at Week 12. Secondary endpoints included CFB in trough FEV₁ at Day 84 and 85. Other endpoints included serial FEV₁ and health status outcomes at Week 12. Safety was evaluated descriptively.

Results

The modified per-protocol population included 720 and 711 patients in studies 207608 and 207609 (intent-to-treat population: 728 and 732). FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0–24-h FEV₁ at Week 12 (Study 207608 treatment difference [95% confidence interval]: 15 mL [− 13, 43]; Study 207609: 11 mL [− 20, 41]). FF/UMEC/VI improved trough FEV₁ CFB versus BUD/FOR+TIO at Day 84 and 85 (Day 85 treatment difference: Study 207608: 38 mL [10, 66]; Study 207609: 51 mL [21, 82]) and FEV₁ at 12 and 24 h post-morning dose at Week 12 in both studies. No treatment differences were seen in health status outcomes. Safety profiles were similar between treatments; pneumonia occurred in 7 (< 1%) patients with FF/UMEC/VI and 9 (1%) patients with BUD/FOR+TIO, across both studies.

Conclusions

FF/UMEC/VI was non-inferior to BUD/FOR+TIO for wmCFB in 0–24-h FEV₁ at Week 12 in patients with COPD. Greater improvements in trough and serial FEV₁ measurements at Week 12 with FF/UMEC/VI versus BUD/FOR+TIO, together with similar health status improvements and safety outcomes including the incidence of pneumonia, suggest that once-daily single-inhaler FF/UMEC/VI triple therapy is a viable option for patients looking to simplify their treatment regimen.

ELLIPTA Versus DISKUS plus HandiHaler in COPD: A Randomized, Open-Label, Crossover Study in a Clinical Trial Setting

BACKGROUND

Inhaler errors among patients with chronic obstructive pulmonary disease (COPD) can reduce treatment efficacy.

METHODS

This randomized, open-label, crossover study evaluated correct use of ELLIPTA versus DISKUS plus HandiHaler. Participants with COPD attended at least 3 study visits (Day 1 [Visit 1], Day 28 [Visit 2], and Day 56 [Visit 3]). Inhalers contained placebo; usual maintenance medication was continued. Participants were randomized to an inhaler sequence (ELLIPTA then DISKUS plus HandiHaler, or the reverse) and preference questionnaire at Visit 1. Participants read the instructions for use in the approved prescribing information for their inhaler(s) and correct use was assessed at Visit 1 (verbal guidance provided if required). Correct use was reassessed at Visit 2, and with the next inhaler(s) at Visit 3. Primary endpoint was the proportion of participants demonstrating correct use (0 errors) with the assigned inhaler(s) after 28 days.

RESULTS

A greater proportion of study participants (n = 217) correctly used ELLIPTA (96%) versus DISKUS plus HandiHaler (87%) after 28 days. The odds of demonstrating correct use with ELLIPTA were 6.88 times that of DISKUS plus HandiHaler (p < 0.001). Overall, > 99% of participants made 0 critical errors (errors leading to no or significantly reduced medication inhaled) with ELLIPTA versus 89% with DISKUS plus HandiHaler after 28 days. ELLIPTA was the patient-preferred option versus DISKUS plus HandiHaler or no preference (p < 0.001).

CONCLUSIONS

Delivery of COPD maintenance therapy via ELLIPTA demonstrates higher correct use rates and lower critical error rates compared with DISKUS plus HandiHaler.

Triple Therapy in COPD

:

Triple inhaled therapy for Chronic Obstructive Pulmonary Disease (COPD) includes an inhaled corticosteroid (ICS), a long-acting b2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) taken in combination. Triple therapy is recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) for patients who experience recurrent exacerbations despite treatment with either a dual bronchodilator or LABA/ICS combination. There is consistent evidence that the LABA/LAMA/ICS combination has significantly greater effects on trough FEV1, symptoms, quality of life, and exercise performance compared to comparator treatments.

:

The role of triple therapy in reducing exacerbations in COPD patients is debatable, but recent trials have revealed some intriguing insights.

Three pivotal studies, namely TRILOGY, TRINITY and TRIBUTE have been conducted to evaluate the safety and efficacy of extrafine Beclomethasone/Formoterol Fumarate/Glycopyrronium Bromide (BDP/FF/GB) versus different treatment options for COPD. Extrafine BDP/FF/GB has been compared to an ICS/LABA (BDP/FF) combination in the TRILOGY study, to a LAMA monotherapy (Tiotropium-TIO) and an extemporary triple combination of ICS/LABA + LAMA (BDP/FF + TIO) in the TRINITY study, and to one inhalation of LABA/LAMA per day (Indacaterol/ Glycopyrronium - IND/GLY) in the TRIBUTE study.

Another triple therapy with Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI) was recently tested in two further studies that included patients with COPD. The FULFIL study compared the efficacy of the triple FF/UMEC/VI therapy to the ICS/LABA association budesonide/formoterol, while the IMPACT study compared the rate of moderate and severe exacerbations between singleinhaler FF/UMEC/VI and single-inhaler FF/VI or UMEC/VI.

The effects of single inhaler triple therapy vs single inhaler dual therapy or separate triple therapy for the management of chronic obstructive pulmonary disease: a systematic review and meta-analysis of randomized controlled trials

Background

This study aims to compare the effects of single inhaler triple therapy comprised of inhaled corticosteroids (ICSs), long-acting β2-agonists (LABAs), and long-acting muscarinic receptor antagonists (LAMAs) with dual therapies comprised of either LABA/LAMA, ICS/LABA or separate ICS/LABA plus LAMA triple therapy.

Methods

The Pubmed, Embase, and Cochrane databases were searched up to October 31st 2018. Only randomized controlled trials were included in the meta-analysis. The primary outcome was the rate of moderate-to-severe chronic obstructive pulmonary disease (COPD) exacerbations.

Results

Seven studies fulfilling the inclusion criteria were included in the meta-analysis. Single inhaler triple therapy was associated with a significantly lower risk of COPD exacerbation compared with LABA/LAMA (rate ratio, 0.69; 95% confidence interval [CI] 0.55 to 0.87, I²=85%), and ICS/LABA (rate ratio, 0.81; 95% CI 0.73 to 0.89, I²=29%) dual therapy. Single inhaler triple therapy led to a more significant improvement in lung function and quality of life compared with LABA/LAMA and ICS/LABA dual therapy. Single inhaler triple therapy was associated with a higher risk of pneumonia compared with LABA/LAMA (risk ratio, 1.38, 95% CI 1.14 to 1.67, I²=0) dual therapy.

Conclusions

The use of single inhaler triple therapy for COPD patients can result in lower rates of moderate or severe exacerbations of COPD as well as improved lung function and quality of life compared with dual therapy with LABA/LAMA or ICS/LABA.

Triple versus dual inhaler therapy in moderate-to-severe COPD: A systematic review and meta-analysis of randomized controlled trials

INTRODUCTION

Treatment of chronic obstructive pulmonary disease (COPD) is evolving specially with triple inhaler therapy.

OBJECTIVES

To perform a meta-analysis to ascertain the safety and efficacy of triple inhaler therapy consisting of an inhaled-glucocorticoid (ICS), long-acting muscarinic antagonist (LAMA) and long-acting beta2-agonist (LABA) when compared with dual therapy (ICS-LABA or LAMA-LABA).

METHODS

We performed an electronic database search to include randomized controlled trials (RCTs) comparing between triple and dual inhalers. Pooled rate-ratio (RR) or odds-ratio (OR) for dichotomous data and weighted mean difference (MD) for continuous data were calculated with their corresponding 95% confidence interval (CI).

RESULTS

Our study included 12 RCTs totaling 19,322 patients, mean age of 65 ± 8.2 years and 68.2% were male. Pooled analysis demonstrated a significant reduction in moderate-to-severe COPD exacerbations with triple therapy (RR 0.75; 95% CI 0.69-0.83; P < 0.01). Additionally, triple therapy caused significant increase in trough FEV1 (MD 0.09 L; 95% CI 0.07-0.12; P < 0.01), significant reduction in the mean St. George's Respiratory Questionnaire (SGRQ) score (MD -1.67; 95% CI -2.02- -1.31; P < 0.01), and more patients experienced ≥ 4 points reduction of SGRQ score (OR 1.27; 95% CI 1.19-1.35; P < 0.01). Triple therapy was associated with an increased risk of pneumonia when compared to LABA/LAMA (OR 1.25; 95% 1.03-1.97; P = 0.03) but there were no significant differences in other adverse events between triple and dual inhalers.

CONCLUSIONS

Among patients with moderate-to-severe COPD, triple inhaler therapy was associated with a reduction of moderate-to-severe COPD exacerbations, improved lung function and improved quality of life when compared to dual inhaler therapy but with an increased pneumonia risk.

Clinical burden of illness among patients with severe eosinophilic COPD

Background: There are currently limited real-world data on the clinical burden of illness in patients with COPD who continue to exacerbate despite receiving triple therapy. The aim of this study was to compare the burden of COPD in patients with and without a phenotype characterized by a high blood eosinophil count and high risk of exacerbations while receiving triple therapy.

Methods: This retrospective cohort study (GSK ID: 207323/PRJ2647) used UK Clinical Practice Research Datalink records linked with Hospital Episode Statistics. Eligible patients had a COPD medical diagnosis code recorded between January 1, 2004 and December 31, 2014, and a blood eosinophil count recorded on/after that date. Patients were followed from index date (first qualifying blood eosinophil count) until December 31, 2015. The study phenotype was defined as ≥2 moderate/≥1 severe acute exacerbation of COPD (AECOPD) in the year prior to the index date, current use of multiple-inhaler triple therapy (MITT), and blood eosinophil count ≥150 cells/µL on the index date. Outcomes measured during follow-up included moderate/severe AECOPDs, severe AECOPDs, all-cause mortality, primary care (GP) clinical consultations, and non-AECOPD-related unscheduled hospitalizations.

Results: Of 46,814 patients eligible for inclusion, 2512 (5.4%) met the definition of the study phenotype. Adjusted rate ratios (95% CI) of moderate/severe AECOPDs and all-cause mortality in patients with the study phenotype versus those without were 2.32 (2.22, 2.43) and 1.26 (1.16, 1.37), respectively. For GP visits and non-AECOPD-related unscheduled hospitalizations, adjusted rate ratios (95% CI), in patients with the study phenotype versus those without, were 1.09 (1.05, 1.12) and 1.31 (1.18, 1.46), respectively.

Conclusion: Patients with COPD and raised blood eosinophil counts who continue to exacerbate despite MITT represent a distinct subgroup who experience substantial clinical burden and account for high healthcare expenditure. There is a need for more effective management and therapeutic options for these patients.

Exacerbations and health care resource use among patients with COPD in relation to blood eosinophil counts

Purpose

Current understanding of the relationship between COPD phenotype and health care resource utilization (HCRU) is limited. This real-world study evaluated disease burden and HCRU for COPD subgroups prone to exacerbation as defined by blood eosinophil (EOS) count and multiple inhaler triple therapy (MITT) use.

Methods

This was a large-scale, retrospective, longitudinal, observational cohort study using data from the US IBM Watson Explorys real-world database (GSK Study HO-17-18395). The population of interest comprised patients with COPD ≥40 years of age with ≥2 moderate or ≥1 severe exacerbations (prior year) while on inhaled maintenance therapy, with ≥1 blood EOS count. Data were analyzed during the year prior to index date (last COPD encounter between January 1, 2011 and December 31, 2016). Four subgroups were analyzed based on a combination of EOS counts (<150 and ≥150 cells/μL) and MITT use (receiving or not receiving). Among these groups, clinical characteristics, exacerbations, and HCRU were described. A sensitivity analysis that further stratified EOS into four categories (<150, ≥150-<300, ≥300-<500, and ≥500 cells/μL) was also performed.

Results

The COPD population of interest comprised 34,268 patients. Subgroups with EOS ≥150 cells/μL vs <150 cells/μL had more comorbidities and experienced significantly higher mean numbers of moderate exacerbations (not receiving MITT, ≥150 cells/μL vs <150 cells/μL: 1.93 vs 1.82, P<0.0001; receiving MITT 2.26 vs 2.16, P=0.0062) and COPD-related emergency visits (not receiving MITT, ≥150 cells/μL vs <150 cells/μL: 3.0 vs 2.5, P<0.001; receiving MITT 3.4 vs 3.1, P=0.0011). Increasing EOS category was associated with higher HCRU.

Conclusion

Blood EOS ≥150/μL cells were associated with increased HCRU and higher exacerbation rates compared with EOS <150 cells/μL, irrespective of MITT use. COPD phenotyping using blood EOS could help identify candidates for additional therapies that target eosinophilic inflammatory pathways.

Adding a LAMA to ICS/LABA Therapy: A Meta-analysis of Triple Combination Therapy in COPD

BACKGROUND

Inhaled corticosteroid (ICS)/long-acting β₂-agonist (LABA) combination is commonly prescribed to treat COPD; therefore, we performed a meta-analysis on the effect of adding a long-acting muscarinic receptor antagonist (LAMA) to ICS/LABA combination in COPD.

METHODS

Studies were identified by searching in different databases the randomized controlled trials that investigated the effect of ICS/LABA/LAMA combination in COPD. The primary end points were the effect of triple therapy on trough FEV₁, risk of acute exacerbation of COPD (AECOPD), and risk of cardiovascular serious adverse events (SAEs), compared with ICS/LABA combination. The Grading of Recommendations Assessment, Development, and Evaluation system was used to assess the quality of evidence.

RESULTS

Thirteen randomized controlled trials including 15,519 patients with COPD (ICS/LABA/LAMA combination, 53.1%; ICS/LABA combination, 46.9%) were meta-analyzed. ICS/LABA/LAMA combination improved trough FEV₁ (mean difference, +104.86 mL; 95% CI, 86.74-122.99; high quality of evidence) and protected against AECOPD (relative risk, 0.78; 95% CI, 0.71-0.85; high quality of evidence) vs ICS/LABA combination. For every approximately four patients treated with triple therapy, one increased FEV₁ > 100 mL, and approximately 26 patients had to be treated for 1 year with ICS/LABA/LAMA combination to prevent one AECOPD, compared with ICS/LABA combination. Adding a LAMA to ICS/LABA therapy did not modulate the risk of cardiovascular SAEs (moderate quality of evidence).

CONCLUSIONS

Triple therapy provides significant clinical benefit in patients with COPD on ICS/LABA combination. ICS/LABA therapy can be escalated to triple therapy without a real risk to increase cardiovascular SAEs when a LAMA is added to the combination.

Triple therapy (ICS/LABA/LAMA) in COPD: time for a reappraisal

Recently, two "fixed triple" single-inhaler combinations of an inhaled corticosteroid (ICS), a long-acting β₂-agonist (LABA), and a long-acting muscarinic antagonist (LAMA) have become available for patients with COPD. This review presents the clinical evidence that led to the approval of these triple therapies, discusses the role of ICS in patients with COPD, and presents data on the relative efficacy of "fixed triple" (ICS/LAMA/LABA) therapy vs LAMA, ICS/LABA, and LAMA/LABA combinations, and summarizes studies in which ICS/LABAs were combined with LAMAs to form "open triple" combinations. Of the five main fixed triple studies completed so far, three evaluated the efficacy and safety of an extrafine formulation of beclometasone dipropionate, formoterol fumarate, and glycopyrronium; the other two studies evaluated fluticasone furoate, vilanterol, and umeclidinium. Overall, compared to LAMA, ICS/LABA, or LAMA/LABA, triple therapy decreased the risk of exacerbations and improved lung function and health status, with a favorable benefit-to-harm ratio. Furthermore, triple therapy showed a promising signal in terms of improved survival. The evidence suggests that triple therapy is the most effective treatment in moderate/severe symptomatic patients with COPD at risk of exacerbations, with marginal if any risk of side effects including pneumonia. Ongoing studies are examining the role of triple therapy in less severe symptomatic patients with COPD and asthma-COPD overlap.

Fluticasone furoate, umeclidinium bromide, and vilanterol as a combination therapy for chronic obstructive pulmonary disease

Introduction: Triple therapy with two bronchodilators (LABA plus LAMA) and an inhaled corticosteroid (ICS) is recommended for patients suffering from severe chronic obstructive pulmonary disease (COPD). Areas covered: All 12-52 week-long studies comparing triple therapy with umeclidinium (UM) added to either fluticasone furoate/vilanterol (FF/VI) or fluticasone propionate/salmeterol (FP/SAL) vs. other comparators in COPD patients of group B or D (2011 GOLD classification) were considered. When UM was added to ICS/LABA with separate devices or within a single device, triple combination was more effective than comparators (usually, ICS/LABA combinations) regarding improvements to pulmonary function, symptoms, quality of life and, in the longer studies, rate of moderate-severe exacerbations. The IMPACT study (a large trial comparing UM/FF/VI with both FF/VI and UM/VI combinations) showed that triple therapy had a greater effect compared to dual therapies in reducing the rate of moderate-severe exacerbations, improving trough FEV1 and improving quality of life. The safety profile was good, without excess cardiovascular effects or pneumonia, however, the presence of comorbidities was frequent. Expert commentary: UM/FF/VI combination represents a good option for severe COPD patients who remain symptomatic and/or with frequent exacerbations despite dual therapies. Once daily administration with a simple and effective device may increase adherence and efficacy of the treatment.

Triple therapy in the management of chronic obstructive pulmonary disease: systematic review and meta-analysis

OBJECTIVE

To compare the rate of moderate to severe exacerbations between triple therapy and dual therapy or monotherapy in patients with chronic obstructive pulmonary disease (COPD).

DESIGN

Systematic review and meta-analysis of randomised controlled trials.

DATA SOURCES

PubMed, Embase, Cochrane databases, and clinical trial registries searched from inception to April 2018.

ELIGIBILITY CRITERIA

Randomised controlled trials comparing triple therapy with dual therapy or monotherapy in patients with COPD were eligible. Efficacy and safety outcomes of interest were also available.

DATA EXTRACTION AND SYNTHESIS

Data were collected independently. Meta-analyses were conducted to calculate rate ratios, hazard ratios, risk ratios, and mean differences with 95% confidence intervals. Quality of evidence was summarised in accordance with GRADE methodology (grading of recommendations assessment, development, and evaluation).

RESULTS

21 trials (19 publications) were included. Triple therapy consisted of a long acting muscarinic antagonist (LAMA), long acting β agonist (LABA), and inhaled corticosteroid (ICS). Triple therapy was associated with a significantly reduced rate of moderate or severe exacerbations compared with LAMA monotherapy (rate ratio 0.71, 95% confidence interval 0.60 to 0.85), LAMA and LABA (0.78, 0.70 to 0.88), and ICS and LABA (0.77, 0.66 to 0.91). Trough forced expiratory volume in 1 second (FEV1) and quality of life were favourable with triple therapy. The overall safety profile of triple therapy is reassuring, but pneumonia was significantly higher with triple therapy than with dual therapy of LAMA and LABA (relative risk 1.53, 95% confidence interval 1.25 to 1.87).

CONCLUSIONS

Use of triple therapy resulted in a lower rate of moderate or severe exacerbations of COPD, better lung function, and better health related quality of life than dual therapy or monotherapy in patients with advanced COPD.

Preventing Clinically Important Deterioration of COPD with Addition of Umeclidinium to Inhaled Corticosteroid/Long-Acting β2-Agonist Therapy: An Integrated Post Hoc Analysis

INTRODUCTION

Assessing clinically important measures of disease progression is essential for evaluating therapeutic effects on disease stability in chronic obstructive pulmonary disease (COPD). This analysis assessed whether providing additional bronchodilation with the long-acting muscarinic antagonist umeclidinium (UMEC) to patients treated with inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) therapy would improve disease stability compared with ICS/LABA therapy alone.

METHODS

This integrated post hoc analysis of four 12-week, randomized, double-blind trials (NCT01772134, NCT01772147, NCT01957163, NCT02119286) compared UMEC 62.5 µg with placebo added to open-label ICS/LABA in symptomatic patients with COPD (modified Medical Research Council dyspnea scale score ≥ 2). A clinically important deterioration (CID) was defined as: a decrease from baseline of ≥ 100 mL in trough forced expiratory volume in 1 s (FEV1), an increase from baseline of ≥ 4 units in St George's Respiratory Questionnaire (SGRQ) total score, or a moderate/severe exacerbation. Risk of a first CID was evaluated in the intent-to-treat (ITT) population and in patients stratified by Global initiative for chronic Obstructive Lung Disease (GOLD) classification, exacerbation history and type of ICS/LABA therapy. Adverse events (AEs) were also assessed.

RESULTS

Overall, 1637 patients included in the ITT population received UMEC + ICS/LABA (n = 819) or placebo + ICS/LABA (n = 818). Additional bronchodilation with UMEC reduced the risk of a first CID by 45-58% in the ITT population and all subgroups analyzed compared with placebo (all p < 0.001). Improvements were observed in reducing FEV1 (69% risk reduction; p < 0.001) and exacerbation (47% risk reduction; p = 0.004) events in the ITT population. No significant reduction in risk of a SGRQ CID was observed. AE incidence was similar between treatment groups.

CONCLUSION

Symptomatic patients with COPD receiving ICS/LABA experience frequent deteriorations. Additional bronchodilation with UMEC significantly reduced the risk of CID and provided greater short-term stability versus continued ICS/LABA therapy in these patients.

Effect of background long-acting beta2-agonist therapy on the efficacy and safety of a novel, nebulized glycopyrrolate in subjects with moderate-to-very-severe COPD

Background

Phase III studies demonstrated efficacy and safety of nebulized glycopyrrolate inhalation solution (GLY) in subjects with COPD. Secondary analyses were performed to examine the effect of background long-acting beta₂-agonist (LABA) use on the efficacy and safety of nebulized GLY.

Methods

In two 12-week placebo-controlled studies (GOLDEN 3 and GOLDEN 4) and one 48-week, open-label active-controlled study (GOLDEN 5), a total of 2,379 subjects were stratified by background LABA use (LABA-yes: n=861; LABA-no: n=1,518) and randomized to placebo vs GLY 25 or 50 µg twice daily, or GLY 50 µg twice daily vs tiotropium (TIO) 18 µg once daily. Lung function, patient-reported outcomes, exacerbations, and safety were assessed.

Results

Compared with placebo, pooled data from the 12-week studies showed significant improvements from baseline with GLY 25 and 50 µg across LABA subgroups in trough FEV₁ (LABA-yes: 0.101 and 0.110 L; LABA-no: 0.092 and 0.101 L, respectively; P<0.001) and St George’s Respiratory Questionnaire total score (SGRQ; LABA-yes: −2.957 and −3.888; LABA-no: −3.301 and −2.073, respectively; P<0.05). Incidence of treatment-emergent adverse events (TEAEs) was similar in LABA subgroups, and lower in GLY 25 µg vs placebo. In the 48-week active-controlled study, GLY and TIO both showed improvement from baseline across LABA subgroups in FEV₁ (LABA-yes: 0.106 and 0.092 L; LABA-no: 0.096 and 0.096 L, respectively) and in SGRQ total score (LABA-yes: −5.190 and −3.094; LABA-no: −4.368 and −4.821, respectively). Incidence of TEAEs was similar between GLY and TIO, and across LABA subgroups. Exacerbation rates were similar across treatments and LABA subgroups, and cardiovascular events of special interest were more frequent in the LABA-no subgroup. Nebulized GLY, combined with LABA, did not generate any additional safety signals.

Conclusion

Nebulized GLY demonstrated efficacy and was well tolerated up to 48 weeks in subjects with COPD with/without background LABA.

Treatment of Chronic Obstructive Pulmonary Disease in the Primary Care Setting: How Can We Achieve More for Our Patients?

Chronic obstructive pulmonary disease is a debilitating and progressive disease that is both underdiagnosed and undertreated, affecting up to 1 in 10 older adults. Common symptoms, including dyspnea, productive cough, chest tightness, and fatigue, can reduce quality of life, the ability to participate in all types of activities, and overall health status in patients. Minimizing the impact of symptoms on patients' quality of life should be a key goal for physicians, and modest changes in current practice could make improvements in patients' lives. Here we review chronic obstructive pulmonary disease, its impact on patients, and how to improve symptom management.

A randomized trial of symptom-based management in Japanese patients with COPD

Background

The Global initiative for chronic Obstructive Lung Disease strategy document for COPD recommends treatment changes according to the persistence of symptoms or exacerbations. This study assessed the feasibility and outcomes of a structured step-up/step-down treatment approach in a randomized controlled clinical trial setting.

Methods

Japanese patients with moderate-to-severe COPD were randomized to blinded, double-dummy treatment with twice-daily fluticasone propionate/salmeterol (FP/SAL) 250/50 µg or once-daily tiotropium bromide (TIO) 18 µg for 24 weeks (dual bronchodilator was not available). At 4-weekly intervals, patients remaining symptomatic (COPD Assessment Test score >10) or experiencing an exacerbation were offered the option to use triple therapy. Primary endpoint was the proportion of patients remaining on randomized therapy.

Results

In total, 406 patients participated (mean FEV₁ 59%±13% predicted; COPD Assessment Test 12±6). Of these, 204 and 201 patients were included in the FP/SAL and TIO groups, respectively, of whom 67% and 63% continued treatment throughout the study; this difference was not statistically significant. Time to first therapy switch was longer with FP/SAL, but not significantly (P=0.21). More patients in Global initiative for chronic Obstructive Lung Disease (2011 criteria) groups C/D switched (FP/SAL 55%, TIO 63%) than in groups A/B (FP/SAL 27%, TIO 27%).

Conclusion

Given the choice, patients with more symptoms or those experiencing an exacerbation will agree to step-up therapy. Effectiveness of disease management pathways can be tested using double-blind studies.

Single inhaler triple therapy with extrafine beclomethasone, formoterol, and glycopyrronium for the treatment of chronic obstructive pulmonary disease

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) management focuses on the alleviation of symptoms and prevention of exacerbations. Inhaled long acting bronchodilators and inhaled corticosteroids (ICS) are the main classes of treatment for COPD. Triple therapy with a long acting beta₂-agonist (LABA), long acting muscarinic antagonist (LAMA), and ICS is commonly prescribed for symptomatic COPD patients experiencing regular exacerbations. Triple therapy is usually administered using separate inhalers; there is little clinical trial evidence of an effect on exacerbation prevention with this approach. Areas covered: This evaluation reviews the single inhaler extrafine combination containing beclometasone diproprionate (BDP), formoterol fumarate (FF), and glycopyrronium bromide (GB) which has been developed as a simplified triple regime. BDP/FF/GB significantly reduced exacerbation rates in three clinical trials (1-year duration) compared against LAMA monotherapy (20% exacerbation reduction), ICS/LABA combination (23% exacerbation reduction), and LAMA/LABA combination (15% exacerbation reduction). Expert opinion: The practical benefits of single inhaler triple therapy in the real world have not been studied. However, the robust clinical trial evidence that BDP/FF/GB reduces exacerbations compared to double combination treatments and LAMA monotherapy cements triple therapy positioning as an escalation step in COPD management pathways.

Management of severe COPD exacerbations: focus on beclomethasone dipropionate/formoterol/glycopyrronium bromide

The major determinant of the decline in lung function, quality of life, and the increased mortality risk in patients with COPD is represented by severe acute exacerbations of the disease, that is, those requiring patients’ hospitalization, constituting a substantial social and health care burden in terms of morbidity and medical resource utilization. Different long-term therapeutic strategies have been proposed so far in order to prevent and/or reduce the clinical and social impact of these events, the majority of which were extrapolated from trials initially focused on the effect of long-acting muscarinic antagonist and subsequently on the efficacy of long-acting β2-agonists in combination or not with inhaled corticosteroids. The option to employ all three classes of molecules combined, despite the limited amount of evidence in our possession, represents a choice currently proposed by international guidelines; however, current recommendations are often based mainly on observational studies or on the results of secondary outcomes in randomized controlled trials. The present narrative review evaluates the available trials that investigated the efficacy of inhaled therapy to prevent COPD exacerbations and especially severe ones, with a particular focus on beclomethasone dipropionate/formoterol/glycopyrronium bromide fixed dose combination, which is the first treatment that comprises all the three drug classes, specifically tested for the prevention of moderate and severe COPD exacerbations.

Pharmacokinetics of Co-Suspension Delivery Technology Budesonide/Glycopyrronium/Formoterol Fumarate Dihydrate (BGF MDI) and Budesonide/Formoterol Fumarate Dihydrate (BFF MDI) Fixed-Dose Combinations Compared With an Active Control: A Phase 1, Randomized, Single-Dose, Crossover Study in Healthy Adults

This randomized, phase 1, single-dose, crossover study (NCT02189304) compared the 12-hour pharmacokinetic (PK) and safety profiles of budesonide/glycopyrronium/formoterol fumarate dihydrate metered dose inhaler (BGF MDI) 320/14.4/10 μg and budesonide/formoterol fumarate dihydrate (BFF) MDI 320/10 μg (both formulated using innovative co-suspension delivery technology) to an active comparator (budesonide/formoterol fumarate dihydrate dry powder inhaler [BUD/FORM DPI] 320/9-μg delivered dose) in healthy adults. The potential for PK interaction between glycopyrronium and budesonide/formoterol within BGF MDI was assessed. Of 72 subjects randomized, 59 completed treatment. Systemic budesonide exposure (primary objective) based on area under the plasma drug concentration-time curve 0-12 hours (AUC_0-12 ; % coefficient of variation) was 1598.38 (49.7), 1657.09 (50.4), and 1276.75 (70.4) pg·h/mL for BGF MDI, BFF MDI, and BUD/FORM DPI, respectively; and formoterol exposure (AUC_0-12 [% coefficient of variation]) was 39.16 (45.9), 39.53 (40.5), and 23.24 (59.2) pg·h/mL, respectively. BGF MDI and BFF MDI were bioequivalent for budesonide and formoterol. All treatments were well tolerated. While systemic exposure to budesonide and formoterol was higher for BGF MDI and BFF MDI than for BUD/FORM DPI, there were no appreciable differences in the incidence of pharmacologically predictable adverse events. This, coupled with the absence of PK interactions, suggests the BGF MDI safety profile will be comparable to BUD/FORM DPI.

Inhaled glycopyrrolate for the treatment of chronic obstructive pulmonary disease

Long-acting muscarinic antagonists (LAMAs), along with long-acting β2-agonists (LABAs), are the mainstay for treatment of patients with COPD. Glycopyrrolate, or glycopyrronium bromide, like other LAMAs, inhibits parasympathetic nerve impulses by selectively blocking the binding of acetylcholine to muscarinic receptors. Glycopyrrolate is unusual in that it preferentially binds to M3 over M2 muscarinic receptors, thereby specifically targeting the primary muscarinic receptor responsible for bronchoconstriction occurring in COPD. Inhaled glycopyrrolate is slowly absorbed from the lungs and rapidly eliminated from the bloodstream, most likely by renal excretion in its unmetabolized form, limiting the potential for systemic adverse events. Inhaled glycopyrrolate is a fast-acting, efficacious treatment option for patients with moderate-severe COPD. It improves lung function, reduces the risk of exacerbations, and alleviates the symptoms of breathlessness, which in turn may explain the improvement seen in patients' quality of life. Inhaled formulations containing glycopyrrolate are well tolerated, and despite being an anticholinergic, few cardiovascular-related events have been reported. Inhaled glycopyrrolate is thus of value as both monotherapy and in combination with other classes of medication for maintenance treatment of COPD. This review covers the mechanism of action of inhaled glycopyrrolate, including its pharmacokinetic, pharmacodynamic, and safety profiles, and effects on mucus secretion. It also discusses the use of inhaled glycopyrrolate in the treatment of COPD, as monotherapy and in fixed-dose combinations with LABAs and inhaled corticosteroid-LABAs, including a triple therapy recently approved in Europe.

Efficacy, safety, and pharmacokinetics of budesonide/formoterol fumarate delivered via metered dose inhaler using innovative co-suspension delivery technology in patients with moderate-to-severe COPD

Purpose

This study investigated the efficacy, safety, and pharmacokinetics of the inhaled corticosteroid/long-acting β₂-agonist fixed-dose combination budesonide/formoterol fumarate (BFF) metered dose inhaler (MDI), compared with the monocomponents budesonide (BD) MDI and formoterol fumarate (FF) MDI, in patients with moderate-to-severe COPD.

Materials and methods

In this Phase IIb, randomized, double-blind, four-period, five-treatment, incomplete-block, crossover study (NCT02196077), all patients received BFF MDI 320/9.6 μg and FF MDI 9.6 μg, and two of either BFF MDI 160/9.6 μg, BFF MDI 80/9.6 μg, or BD MDI 320 μg twice daily for 28 days. The primary efficacy endpoint was forced expiratory volume in 1 second area under the curve from 0 to 12 hours on Day 29. Secondary efficacy endpoints included additional lung function assessments, and evaluation of dyspnea and rescue medication use. Safety was monitored throughout. The systemic exposure to budesonide and formoterol was assessed on Day 29.

Results

Overall, 180 patients were randomized. For forced expiratory volume in 1 second area under the curve from 0 to 12 hours on Day 29, all BFF MDI doses showed significant improvements versus BD MDI 320 μg (least squares mean differences 186–221 mL; all p<0.0001), and BFF MDI 320/9.6 μg demonstrated a significant improvement versus FF MDI 9.6 μg (least squares mean difference 56 mL; p=0.0013). Furthermore, all BFF MDI doses showed significant improvements versus BD MDI 320 μg for all lung function, dyspnea, and rescue medication use secondary efficacy endpoints. All BFF MDI doses were well tolerated, and the safety profile was not substantially different from the monocomponents. There was no evidence of clinically meaningful pharmacokinetic interactions when budesonide and formoterol were formulated together in BFF MDI.

Conclusion

The findings presented here confirm that BFF MDI 320/9.6 μg is an appropriate dose to take forward into Phase III studies in patients with COPD.

Practical considerations when prescribing a long-acting muscarinic antagonist for patients with COPD

COPD is characterized by persistent airflow limitation, progressive breathlessness, cough, and sputum production. Long-acting muscarinic antagonists (LAMAs) are one of the recommended first-choice therapeutic options for patients with COPD, and several new agents have been developed in recent years. A literature search identified 14 published randomized, placebo-controlled studies of the efficacy and safety of LAMAs in patients with COPD, with improvements seen in lung function, exacerbations, breathlessness, and health status. A greater weight of evidence currently exists for glycopyrronium (GLY) and tiotropium than for umeclidinium and aclidinium, especially in terms of exacerbation reductions. To date, there have been few head-to-head clinical studies of the different LAMAs. Available data indicate that GLY and aclidinium have similar efficacy to tiotropium in terms of improving lung function, dyspnea, exacerbations, and health status. Overall, evidence demonstrates that currently available LAMAs provide effective and generally well-tolerated therapy for patients with COPD. Delivery devices for the different LAMAs vary, which may affect individual patient's adherence to and preference for treatment. Subtle differences between individual therapeutic options may be important to individual patients and the final treatment choice should involve physician's and patient's experiences and preferences.

Triple therapy in COPD: new evidence with the extrafine fixed combination of beclomethasone dipropionate, formoterol fumarate, and glycopyrronium bromide

The goals of COPD therapy are to prevent and control symptoms, reduce the frequency and severity of exacerbations, and improve exercise tolerance. The triple combination therapy of inhaled corticosteroids (ICSs), long-acting beta₂ agonists (LABAs), and long-acting muscarinic antagonists (LAMAs) has become an option for maintenance treatment of COPD and as a “step-up” therapy from single or double combination treatments. There is evidence that triple combination ICS/LABA/LAMA with different inhalers improves lung function, symptoms, and health status and reduces exacerbations. A new triple fixed-dose combination of extrafine beclomethasone dipropionate (100 µg/puff)/formoterol fumarate (6 µg/puff)/glycopyrronium bromide (12.5 µg/puff) has been developed as a hydrofluoroalkane pressurized metered dose inhaler. Two large pivotal studies showed that this extrafine fixed ICS/LABA/LAMA triple combination is superior to fixed ICS/LABA combined therapy and also superior to the LAMA tiotropium in terms of lung function and exacerbation prevention in COPD patients at risk of exacerbation. This review considers the new information provided by these clinical trials of extrafine triple therapy and the implications for the clinical management of COPD patients.

Spotlight on glycopyrronium/formoterol fumarate inhalation aerosol in the management of COPD: design, development, and place in therapy

Long-acting bronchodilators are the mainstay of the treatment of COPD. With the advent of several combination inhalers with long-acting antimuscarinic agents (LAMAs) and long-acting beta agonists (LABAs), the choice of therapy in the treatment of COPD has been ever expanding. With the focus of COPD management shifting from FEV₁-based treatment escalation to symptoms and risk-based treatment, we are seeing a paradigm shift in COPD treatment with early introduction of LAMA-LABA combination as a single inhaler. Glycopyrronium/formoterol fumarate fixed-dose combination formulated in a familiar metered-dose inhaler format using proprietary co-suspension technology is a new option on the market. We purport to discuss the evidence behind the approval of the drug combination and its place in therapy.

Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Lung Disease 2017 Report. GOLD Executive Summary

This Executive Summary of the Global Strategy for the Diagnosis, Management, and Prevention of COPD, Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 report focuses primarily on the revised and novel parts of the document. The most significant changes include: (1) the assessment of chronic obstructive pulmonary disease has been refined to separate the spirometric assessment from symptom evaluation. ABCD groups are now proposed to be derived exclusively from patient symptoms and their history of exacerbations; (2) for each of the groups A to D, escalation strategies for pharmacologic treatments are proposed; (3) the concept of deescalation of therapy is introduced in the treatment assessment scheme; (4) nonpharmacologic therapies are comprehensively presented; and (5) the importance of comorbid conditions in managing chronic obstructive pulmonary disease is reviewed.

Bronchodilator efficacy of extrafine glycopyrronium bromide: the Glyco 2 study

An extrafine formulation of the long-acting muscarinic antagonist glycopyrronium bromide (GB) is in development for chronic obstructive pulmonary disease (COPD), in combination with beclometasone dipropionate and formoterol fumarate - a "fixed triple". This two-part study was randomized, double blind, placebo controlled in patients with moderate-to-severe COPD: Part 1: single-dose escalation, GB 12.5, 25, 50, 100 or 200 μg versus placebo; Part 2: repeat-dose (7-day), four-period crossover, GB 12.5, 25 or 50 μg twice daily (BID) versus placebo, with an open-label extension in which all patients received tiotropium 18 μg once daily. On the morning of Day 8 in all five periods, patients also received formoterol 12 μg. In study Part 1, 27 patients were recruited. All GB doses significantly increased from baseline forced expiratory volume in 1 second (FEV1) area under the curve (AUC0-12h) and peak FEV1, with a trend toward greater efficacy with higher GB dose. All adverse events were mild-moderate in severity, with a lower incidence with GB than placebo and no evidence of a dose-response relationship. In study Part 2, of 38 patients recruited, 34 completed the study. Adjusted mean differences from placebo in 12 h trough FEV1 on Day 7 (primary) were 115, 142 and 136 mL for GB 12.5, 25 and 50 μg BID, respectively (all P<0.001). GB 25 and 50 μg BID were superior (P<0.05) to GB 12.5 μg BID for pre-dose morning FEV1 on Day 8. For this endpoint, GB 25 and 50 μg BID were also superior to tiotropium. Compared with Day 7, addition of formoterol significantly increased Day 8 FEV1 peak and AUC0-12h with all GB doses and placebo (all P<0.001). All adverse events were mild-moderate in severity and there was no indication of a dose-related relationship. This study provides initial evidence on bronchodilation, safety and pharmacokinetics of extrafine GB BID. Overall, the results suggest that GB 25 μg BID is the optimal dose in patients with COPD.

Spanish Guidelines for Management of Chronic Obstructive Pulmonary Disease (GesEPOC) 2017. Pharmacological Treatment of Stable Phase

The clinical presentation of chronic obstructive pulmonary disease (COPD) varies widely, so treatment must be tailored according to the level of risk and phenotype. In 2012, the Spanish COPD Guidelines (GesEPOC) first established pharmacological treatment regimens based on clinical phenotypes. These regimens were subsequently adopted by other national guidelines, and since then, have been backed up by new evidence. In this 2017 update, the original severity classification has been replaced by a much simpler risk classification (low or high risk), on the basis of lung function, dyspnea grade, and history of exacerbations, while determination of clinical phenotype is recommended only in high-risk patients. The same clinical phenotypes have been maintained: non-exacerbator, asthma-COPD overlap (ACO), exacerbator with emphysema, and exacerbator with bronchitis. Pharmacological treatment of COPD is based on bronchodilators, the only treatment recommended in low-risk patients. High-risk patients will receive different drugs in addition to bronchodilators, depending on their clinical phenotype. GesEPOC reflects a more individualized approach to COPD treatment, according to patient clinical characteristics and level of risk or complexity.

Safety of inhaled long-acting anti-muscarinic agents in COPD

Evidence-based guidelines recommend inhaled long-acting anti-muscarinic agents (LAMAs) as first-line maintenance therapy for symptomatic patients with COPD. Several LAMAs are now available for use either as monotherapy or in combination with other COPD medications, including long-acting β₂-agonists (LABAs) or inhaled corticosteroids (ICS). The efficacy and long-term safety of these medications have been evaluated in multiple clinical trials and real-life studies. This review evaluates the evidence available on the safety of existing LAMAs alone or in combination with LABAs and ICS in patients with COPD.
