Abstract
Pulmonary delivery is an alternative route of administration with numerous advantages over conventional routes of administration. It provides low enzymatic exposure, fewer systemic side effects, no first-pass metabolism, and concentrated drug amounts at the site of the disease, making it an ideal route for the treatment of pulmonary diseases. Owing to the thin alveolar-capillary barrier, and large surface area that facilitates rapid absorption to the bloodstream in the lung, systemic delivery can be achieved as well. Administration of multiple drugs at one time became urgent to control chronic pulmonary diseases such as asthma and COPD, thus, development of drug combinations was proposed. Administration of medications with variable dosages from different inhalers leads to overburdening the patient and may cause low therapeutic intervention. Therefore, products that contain combined drugs to be delivered via a single inhaler have been developed to improve patient compliance, reduce different dose regimens, achieve higher disease control, and boost therapeutic effectiveness in some cases. This comprehensive review aimed to highlight the growth of drug combinations by inhalation over time, obstacles and challenges, and the possible progress to broaden the current options or to cover new indications in the future. Moreover, various pharmaceutical technologies in terms of formulation and device in correlation with inhaled combinations were discussed in this review. Hence, inhaled combination therapy is driven by the need to maintain and improve the quality of life for patients with chronic respiratory diseases; promoting drug combinations by inhalation to a higher level is a necessity.

Combination therapy with long-acting bronchodilators and the risk of major adverse cardiovascular events in patients with COPD: a systematic review and meta-analysis. Eur Respir J 2023; 61:2200302. [PMID: 36137586 DOI: 10.1183/13993003.00302-2022] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 09/07/2022] [Indexed: 11/05/2022]
Abstract
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.

[PMID: 35001708 PMCID: PMC8743917 DOI: 10.1177/17534666211066068] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 11/11/2021] [Indexed: 11/16/2022] Open
Abstract
OBJECTIVE This study aimed to quantitatively compare the efficacy and safety of long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combinations (FDCs) for the treatment of stable chronic obstructive pulmonary disease (COPD), especially in terms of their loss of efficacy in lung function. METHODS Randomized controlled clinical trials of LABA/LAMA FDCs for the treatment of stable COPD were comprehensively searched for in public databases. Pharmacodynamic models were established to describe the time course of the primary outcome [trough forced expiratory volume in the first second (FEV1)]. Secondary outcomes [COPD exacerbations, St. George's Respiratory Questionnaire (SGRQ), Transition Dyspnoea Index (TDI), and rescue medication use] and safety outcomes [mortality, serious adverse events (SAEs), and withdrawals due to adverse events (AEs)] were also compared via a meta-analysis. RESULTS A total of 22 studies involving 16,486 participants were included in this study. The results showed that in terms of primary outcome (change from baseline in trough FEV1), the efficacy of vilanterol/umeclidinium was the highest, while the efficacy of formoterol/aclidinium was the lowest, with a maximum effect value (Emax) of 0.185 L [95% confidence interval (CI): 0.173-0.197 L] and 0.119 L (95% CI: 0.103-0.135 L), respectively. The efficacy of other drugs, such as formoterol/glycopyrronium, indacaterol/glycopyrronium, and olodaterol/tiotropium, were comparable, and their Emax values were 0.150-0.177 L. Except for vilanterol/umeclidinium, the other four LABA/LAMA FDCs showed a certain degree of loss of efficacy. Compared with the efficacy at 2 days, the trough FEV1 (L) relative to baseline at 24 weeks decreased by 0.029-0.041 L. In terms of secondary outcomes, the efficacy of different LABA/LAMA FDCs was similar in TDI and rescue medication use. However, formoterol/aclidinium was better in preventing the COPD exacerbations, while vilanterol/umeclidinium was the best in terms of SGRQ. In addition, different LABA/LAMA FDCs and placebo had similar safety outcomes. CONCLUSION The present findings may provide necessary quantitative information for COPD medication guidelines.

Abstract
INTRODUCTION Few randomised controlled trials (RCTs) have directly compared long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) dual maintenance therapies for patients with chronic obstructive pulmonary disease (COPD). This systematic literature review and network meta-analysis (NMA) compared the efficacy of umeclidinium/vilanterol (UMEC/VI) versus other dual and mono-bronchodilator therapies in symptomatic patients with COPD. METHODS A systematic literature review (October 2015-November 2020) was performed to identify RCTs ≥ 8 weeks long in adult patients with COPD that compared LAMA/LABA combinations against any long-acting bronchodilator-containing dual therapy or monotherapy. Data extracted on changes from baseline in trough forced expiratory volume in 1 s (FEV1), St George's Respiratory Questionnaire (SGRQ) total score, Transitional Dyspnoea Index (TDI) focal score, rescue medication use and moderate/severe exacerbation rate were analysed using an NMA in a frequentist framework. The primary comparison was at 24 weeks. Fixed effects model results are presented. RESULTS The NMA included 69 full-length publications (including 10 GSK clinical study reports) reporting 49 studies. At 24 weeks, UMEC/VI provided statistically significant greater improvements in FEV1 versus all dual therapy and monotherapy comparators. UMEC/VI provided similar improvements in SGRQ total score compared with all other LAMA/LABAs, and significantly greater improvements versus UMEC 125 μg, glycopyrronium 50 μg, glycopyrronium 18 μg, tiotropium 18 μg and salmeterol 50 μg. UMEC/VI also provided significantly better outcomes versus some comparators for TDI focal score, rescue medication use, annualised moderate/severe exacerbation rate, and time to first moderate/severe exacerbation. CONCLUSION UMEC/VI provided generally better outcomes compared with LAMA or LABA monotherapies, and consistent improvements in lung function (measured by change from baseline in trough FEV1 at 24 weeks) versus dual therapies. Treatment with UMEC/VI may improve outcomes for symptomatic patients with COPD compared with alternative maintenance treatments.

Abstract
Rationale: There is uncertainty on the optimal first-line therapy for symptomatic chronic obstructive pulmonary disease (COPD). Long-acting β2-receptor agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) have long been mainstays of treatment, though it is still not clear if dual therapy with LABA/LAMA is superior to monotherapy for symptomatic COPD.Objectives: To clarify the evidence landscape, we conducted a systematic review to answer the following question: in patients with COPD who complain of dyspnea and/or exercise intolerance, is LABA/LAMA combination therapy more effective and equally safe compared with LABA or LAMA monotherapy?Methods: A search of Medline, EMBASE, and the Cochrane Library databases was conducted by a medical librarian for randomized controlled trials enrolling patients with COPD who complain of dyspnea and/or exercise intolerance that compare LABA/LAMA combination therapy to LABA or LAMA monotherapy. A systematic approach was used to screen, abstract, and critically appraise the emerging study evidence. The Grading of Recommendations Assessment, Development, and Evaluation method was applied to rate the certainty and quality of the evidence.Results: A total of 24 studies were eligible for inclusion (n = 45,441). Pairwise random-effects meta-analysis revealed reductions in hospital admissions (11% reduction; P < 0.01) and acute exacerbations of COPD (20% reduction; P < 0.002), all in favor of LABA/LAMA dual therapy. Although there is reduced dyspnea (0.10 standardized mean difference; P < 0.001) and improved health-related quality of life (-0.13 standardized mean difference; P < 0.001), both values did not meet a clinical meaningful difference threshold. LABA/LAMA combination therapy showed no difference in treatment-emergent adverse effects (risk ratio, 0.99; P = 0.34) when compared with either LAMA or LABA monotherapy.Conclusions: Based on the reviewed evidence, in patients with symptomatic COPD who complain of dyspnea and/or exercise intolerance, dual LABA/LAMA therapy is superior to either LABA or LAMA monotherapy based on the reduced risk of exacerbations and hospitalizations.

Abstract
OBJECTIVE The aim of this study was to review clinical evidence supporting the use of fixed-dose combination of tiotropium and olodaterol, a long-acting muscarinic antagonist (LAMA) and a long-acting β2-agonist (LABA), respectively, as the initial and follow-up treatment choice in patients with chronic obstructive pulmonary disease (COPD) as per Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020 recommendations-the impact of this treatment strategy on the reduction in the risk of exacerbations-and the importance of early therapeutic interventions. METHODS For this narrative review, the available literature was searched to identify studies including patients with COPD receiving tiotropium and olodaterol as either monotherapy or combination therapy and studies including patients with COPD receiving inhaled corticosteroids (ICS) in addition to long-acting bronchodilators. Relevant studies were included in the review. RESULTS Patients with COPD are often prescribed ICS therapy, which, when used over a long term, can be associated with local and systemic adverse effects. The GOLD 2020 report recommends dual bronchodilator therapy as both an initial and follow-up treatment option. A LABA + LAMA combination is mechanistically synergistic, and cumulative evidence surrounding the efficacy and safety of fixed-dose combination of tiotropium and olodaterol supports therapeutic advantages over monotherapy in most patients with COPD. CONCLUSIONS The early stages of COPD may represent a "window of therapeutic opportunity" during which initiation of tiotropium and olodaterol dual bronchodilator therapy may improve lung function and quality of life and reduce exacerbations in patients with COPD.

Abstract
Background: Chronic obstructive pulmonary disease (COPD) guidelines recommend both long-acting and dual bronchodilator therapy. It is unclear if there are differences in efficacy and safety. Objective: This meta-analysis evaluates the efficacy of dual therapy with long-acting β-agonist (LABA) + long acting muscarinic antagonist (LAMA) compared with monotherapy with LAMA for COPD. Methods: We searched PubMed, CINAHL, and Web of Science databases from inception through March 2020 to identify English-language, prospective randomized controlled trials (RCTs) that compared dual therapy with monotherapy in adult patients with COPD. Risk of bias was assessed using the Jadad score. Overall analysis was performed using Review Manager 5.3. Treatment effect was determined with the random-effects model using the Mantel-Haenszel method and was reported as mean difference (MD) with 95% CI. Results: A total of 18 RCTs were included (n = 6086; median Jadad score 5/5) that compared LAMA + LABA with LAMA. There was a greater improvement in forced expiratory volume at 1 s (FEV1) with dual therapy compared with LAMA: MD = 0.08; 95% CI = [0.05, 0.11]. There was no difference in St George Respiratory Questionnaire (SGRQ) scores between groups: OR = −0.85; 95% CI = [−1.83, 0.13]. There were no differences in overall adverse events (OR = 1.00; 95% CI = 0.92, 1.09), serious adverse events (OR = 1.01; 95% CI = 0.86, 1.18), or cardiovascular events (OR = 0.88; 95% CI = 0.58, 1.34). Conclusion and Relevance: Dual therapy improves FEV1 and is as safe as LAMA. Dual therapy does not improve SGRQ scores more than LAMA.

Abstract
Background: This document provides clinical recommendations for the pharmacologic treatment of chronic obstructive pulmonary disease (COPD). It represents a collaborative effort on the part of a panel of expert COPD clinicians and researchers along with a team of methodologists under the guidance of the American Thoracic Society. Methods: Comprehensive evidence syntheses were performed on all relevant studies that addressed the clinical questions and critical patient-centered outcomes agreed upon by the panel of experts. The evidence was appraised, rated, and graded, and recommendations were formulated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Results: After weighing the quality of evidence and balancing the desirable and undesirable effects, the guideline panel made the following recommendations: 1) a strong recommendation for the use of long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) combination therapy over LABA or LAMA monotherapy in patients with COPD and dyspnea or exercise intolerance; 2) a conditional recommendation for the use of triple therapy with inhaled corticosteroids (ICS)/LABA/LAMA over dual therapy with LABA/LAMA in patients with COPD and dyspnea or exercise intolerance who have experienced one or more exacerbations in the past year; 3) a conditional recommendation for ICS withdrawal for patients with COPD receiving triple therapy (ICS/LABA/LAMA) if the patient has had no exacerbations in the past year; 4) no recommendation for or against ICS as an additive therapy to long-acting bronchodilators in patients with COPD and blood eosinophilia, except for those patients with a history of one or more exacerbations in the past year requiring antibiotics or oral steroids or hospitalization, for whom ICS is conditionally recommended as an additive therapy; 5) a conditional recommendation against the use of maintenance oral corticosteroids in patients with COPD and a history of severe and frequent exacerbations; and 6) a conditional recommendation for opioid-based therapy in patients with COPD who experience advanced refractory dyspnea despite otherwise optimal therapy. Conclusions: The task force made recommendations regarding the pharmacologic treatment of COPD based on currently available evidence. Additional research in populations that are underrepresented in clinical trials is needed, including studies in patients with COPD 80 years of age and older, those with multiple chronic health conditions, and those with a codiagnosis of COPD and asthma.

Abstract
Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

Abstract
BACKGROUND Combinations of long-acting bronchodilators with different mechanisms of action are recommended to improve prognosis and reduce risk of adverse events of chronic obstructive pulmonary disease (COPD). It is unclear whether the new combination therapy with long-acting muscarinic antagonist (LAMA) tiotropium (TIO) and long acting beta-agonists (LABA) olodaterol (OLO) was superior to tiotropium alone. METHODS We measured the efficacy of the TIO/OLO combination vsTIO alone for COPD patients based on electronic databases up to February 2019. After rigorous quality review, data was extracted from eligible trials. All the main outcomes were pooled analysis using RevMan software. RESULTS A total of 6 randomized controlled trials (RCTs) were identified. The pooled results of our meta-analysis demonstrated that FEV1 [MD = 0.03, 95% CI (-0.01,0.07), P = .18], FVC [MD = -0.03, 95%CI (-0.06,0.00), P = .09] and FEV1%pred [MD = 0.35, 95%CI (-0.30, 0.99), P = .29] all showed no significant difference between the 2 groups. The overall incidence of adverse effects (AEs) [OR = 1.01,95%CI (0.93,1.09), P = .87] and serious AEs [OR = 1.04,95% CI (0.82, 1.32), P = .72] in the combination group was similar to that of the TIO alone group, without statistical significance. CONCLUSION These studies reported that the TIO/OLO combination did not show superior effects than tiotropium alone for COPD. Additionally, both therapies were well tolerated.

Abstract
Background Reduced physical activity is associated with increased morbidity and mortality in patients with COPD. Studies suggest that treatment with the long-acting muscarinic antagonist tiotropium and the long-acting β2-agonist olodaterol increases exercise capacity. This study assessed the effects of a fixed-dose combination (FDC) of tiotropium/olodaterol (delivered via Respimat®) on physical functioning in patients with stable COPD in a “real-world setting”. Methods An international, open-label, single-arm, non-interventional study conducted in nine countries measuring changes in self-reported physical functioning in COPD patients treated with tiotropium/olodaterol 5/5 μg FDC for approximately 6 weeks. The primary endpoint was therapeutic success, defined as a minimum 10-point increase in the 10-question Physical Functioning Questionnaire (PF-10) score. Secondary endpoints included absolute change in PF-10 from Visit 1 to Visit 2, patient general condition (measured by Physician’s Global Evaluation score) and patient satisfaction with the treatment and device (assessed by Patient Satisfaction Questionnaire at the end of the study period). Results Therapeutic success was observed in 67.8% of 7218 patients (95% CI 66.7, 68.8) in the final analysis set after approximately 6 weeks of treatment with tiotropium/olodaterol. Mean change in PF-10 score between Visit 1 and Visit 2 was 16.6 points (95% CI 16.2, 17.0). Therapeutic success was 64.3% (95% CI 63.0–65.6%) in patients with infrequent (≤1) and 76.1% (95% CI 74.3–77.9%) in patients with frequent (≥2) exacerbations (p<0.0001). Patient general condition improved as indicated by an improvement in Physician’s Global Evaluation scores between visits. Most patients were very satisfied or satisfied with tiotropium/olodaterol treatment in general (81%), reported inhalation satisfaction (85%), and satisfactory handling of the device (84%). 1.3% of patients reported an investigator-defined drug-related adverse event. Conclusion Treatment with tiotropium/olodaterol led to an improvement in self-reported physical functioning in patients with COPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a respiratory condition causing accumulation of mucus in the airways, cough, and breathlessness; the disease is progressive and is the fourth most common cause of death worldwide. Current treatment strategies for COPD are multi-modal and aim to reduce morbidity and mortality and increase patients' quality of life by slowing disease progression and preventing exacerbations. Fixed-dose combinations (FDCs) of a long-acting beta2-agonist (LABA) plus a long-acting muscarinic antagonist (LAMA) delivered via a single inhaler are approved by regulatory authorities in the USA, Europe, and Japan for the treatment of COPD. Several LABA/LAMA FDCs are available and recent meta-analyses have clarified their utility versus their mono-components in COPD. Evaluation of the efficacy and safety of once-daily LABA/LAMA FDCs versus placebo will facilitate the comparison of different FDCs in future network meta-analyses. OBJECTIVES We assessed the evidence for once-daily LABA/LAMA combinations (delivered in a single inhaler) versus placebo on clinically meaningful outcomes in patients with stable COPD. SEARCH METHODS We identified trials from Cochrane Airways' Specialised Register (CASR) and also conducted a search of the US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization International Clinical Trials Registry Platform (apps.who.int/trialsearch). We searched CASR and trial registries from their inception to 3 December 2018; we imposed no restriction on language of publication. SELECTION CRITERIA We included parallel-group and cross-over randomised controlled trials (RCTs) comparing once-daily LABA/LAMA FDC versus placebo. We included studies reported as full-text, those published as abstract only, and unpublished data. We excluded very short-term trials with a duration of less than 3 weeks. We included adults (≥ 40 years old) with a diagnosis of stable COPD. We included studies that allowed participants to continue using their ICS during the trial as long as the ICS was not part of the randomised treatment. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results to determine included studies, extracted data on prespecified outcomes of interest, and assessed the risk of bias of included studies; we resolved disagreements by discussion with a third review author. Where possible, we used a random-effects model to meta-analyse extracted data. We rated all outcomes using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) system and presented results in 'Summary of findings' tables. MAIN RESULTS We identified and included 22 RCTs randomly assigning 8641 people with COPD to either once-daily LABA/LAMA FDC (6252 participants) or placebo (3819 participants); nine studies had a cross-over design. Studies had a duration of between three and 52 weeks (median 12 weeks). The mean age of participants across the included studies ranged from 59 to 65 years and in 21 of 22 studies, participants had GOLD stage II or III COPD. Concomitant inhaled corticosteroid (ICS) use was permitted in all of the included studies (where stated); across the included studies, between 28% to 58% of participants were using ICS at baseline. Six studies evaluated the once-daily combination of IND/GLY (110/50 μg), seven studies evaluated TIO/OLO (2.5/5 or 5/5 μg), eight studies evaluated UMEC/VI (62.5/5, 125/25 or 500/25 μg) and one study evaluated ACD/FOR (200/6, 200/12 or 200/18 μg); all LABA/LAMA combinations were compared with placebo.The risk of bias was generally considered to be low or unknown (insufficient detail provided), with only one study per domain considered to have a high risk of bias except for the domain 'other bias' which was determined to be at high risk of bias in four studies (in three studies, disease severity was greater at baseline in participants receiving LABA/LAMA compared with participants receiving placebo, which would be expected to shift the treatment effect in favour of placebo).Compared to the placebo, the pooled results for the primary outcomes for the once-daily LABA/LAMA arm were as follows: all-cause mortality, OR 1.88 (95% CI 0.81 to 4.36, low-certainty evidence); all-cause serious adverse events (SAEs), OR 1.06 (95% CI 0.88 to 1.28, high-certainty evidence); acute exacerbations of COPD (AECOPD), OR 0.53 (95% CI 0.36 to 0.78, moderate-certainty evidence); adjusted St George's Respiratory Questionnaire (SGRQ) score, MD -4.08 (95% CI -4.80 to -3.36, high-certainty evidence); proportion of SGRQ responders, OR 1.75 (95% CI 1.54 to 1.99). Compared with placebo, the pooled results for the secondary outcomes for the once-daily LABA/LAMA arm were as follows: adjusted trough forced expiratory volume in one second (FEV1), MD 0.20 L (95% CI 0.19 to 0.21, moderate-certainty evidence); adjusted peak FEV1, MD 0.31 L (95% CI 0.29 to 0.32, moderate-certainty evidence); and all-cause AEs, OR 0.95 (95% CI 0.86 to 1.04; high-certainty evidence). No studies reported data for the 6-minute walk test. The results were generally consistent across subgroups for different LABA/LAMA combinations and doses. AUTHORS' CONCLUSIONS Compared with placebo, once-daily LABA/LAMA (either IND/GLY, UMEC/VI or TIO/OLO) via a combination inhaler is associated with a clinically significant improvement in lung function and health-related quality of life in patients with mild-to-moderate COPD; UMEC/VI appears to reduce the rate of exacerbations in this population. These conclusions are supported by moderate or high certainty evidence based on studies with an observation period of up to one year.

Abstract
PURPOSE OF REVIEW Recent updates to the GOLD guidelines emphasize the use of combination LABA and LAMA bronchodilators for patients with chronic obstructive pulmonary disease with persistent dyspnea despite monotherapy or frequent exacerbations despite LAMA monotherapy. There are several commercially available LABA/LAMA fixed dose combination inhalers, which are likely to become the principle therapy for many patients with COPD. RECENT FINDINGS In the last 4 years, there have been a number of large clinical trials evaluating the efficacy and safety of combined LAMA and LABA bronchodilators. LAMA/LABA fixed dose combination therapies have consistently demonstrated clinically significant improvements to airway obstruction, dyspnea, and quality of life whenever compared with placebo, and more modest improvements compared with bronchodilator monotherapies and combined bronchodilator/inhaled corticosteroid therapy. SUMMARY New guidelines emphasize combination bronchodilators as a mainstay of therapy for many patients with symptomatic COPD and there are several new combination bronchodilator therapies available to patients. It is important for physicians and patients to understand the range and degree of expected clinical effects and the safety profiles of these new medications.

Abstract
Background Increasing availability of therapeutic options for COPD may drive new treatment pathways. This study describes COPD treatment in France, focusing on identifying initial treatment modifications in patients with COPD who either initiated long-acting bronchodilator (LABD)-based therapy or escalated to triple therapy (long-acting muscarinic antagonist [LAMA] + long-acting β2-agonist [LABA] + inhaled corticosteroid [ICS]). Methods This retrospective analysis of patients with COPD in a large general practitioner database (IQVIA Longitudinal Patient Database) in France included two cohorts: Cohort 1 – new initiators of LABD-based therapy (LAMA, LABA, LAMA + LABA, LAMA + ICS, LABA + ICS or LAMA + LABA + ICS); Cohort 2 – patients escalating to triple therapy from mono- or dual-bronchodilator-based maintenance treatment. Both cohorts were indexed on the date of initiation/escalation (January 2008–December 2013), and the first treatment modification (at class level) within the 18-month post-index observational period was described. Five mutually exclusive outcomes were defined: continuous use (no modification), discontinuation (permanent [≥91 days with no restart] or temporary [≥91 days with subsequent restart]), switch, and augmentation (Cohort 1 only). Exploratory analysis of Cohort 1 explored potential drivers of treatment initiation. Results Overall, 5,065 patients initiated LABD-based therapy (Cohort 1), and 501 escalated to triple therapy (Cohort 2). In Cohort 1, 7.0% of patients were continuous users, 46.5% discontinued permanently, 28.5% discontinued temporarily, 2.8% augmented (added LAMA and/or LABA and/or ICS), and 15.2% switched therapy. In Cohort 2, 18.2% of patients were continuous users, 7.2% discontinued permanently, 27.9% discontinued temporarily, and 46.7% switched therapy. Exploratory analyses showed that time since COPD diagnosis was first recorded, pre-index exacerbation events, and concomitant medical conditions were potential drivers of initial maintenance treatment choices. Conclusion Discontinuation among new initiators of LABD-based therapy was high in France, whereas few switched or augmented treatment. In comparison, permanent discontinuation within 18 months was low in patients escalating to triple therapy.

Abstract
BACKGROUND Long-acting bronchodilators such as long-acting β-agonist (LABA), long-acting muscarinic antagonist (LAMA), and LABA/inhaled corticosteroid (ICS) combinations have been used in people with moderate to severe chronic obstructive pulmonary disease (COPD) to control symptoms such as dyspnoea and cough, and prevent exacerbations. A number of LABA/LAMA combinations are now available for clinical use in COPD. However, it is not clear which group of above mentioned inhalers is most effective or if any specific formulation works better than the others within the same group or class. OBJECTIVES To compare the efficacy and safety of available formulations from four different groups of inhalers (i.e. LABA/LAMA combination, LABA/ICS combination, LAMA and LABA) in people with moderate to severe COPD. The review will update previous systematic reviews on dual combination inhalers and long-acting bronchodilators to answer the questions described above using the strength of a network meta-analysis (NMA). SEARCH METHODS We identified studies from the Cochrane Airways Specialised Register, which contains several databases. We also conducted a search of ClinicalTrials.gov and manufacturers' websites. The most recent searches were conducted on 6 April 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) that recruited people aged 35 years or older with a diagnosis of COPD and a baseline forced expiratory volume in one second (FEV1) of less than 80% of predicted. We included studies of at least 12 weeks' duration including at least two active comparators from one of the four inhaler groups. DATA COLLECTION AND ANALYSIS We conducted NMAs using a Bayesian Markov chain Monte Carlo method. We considered a study as high risk if recruited participants had at least one COPD exacerbation within the 12 months before study entry and as low risk otherwise. Primary outcomes were COPD exacerbations (moderate to severe and severe), and secondary outcomes included symptom and quality-of-life scores, safety outcomes, and lung function. We collected data only for active comparators and did not consider placebo was not considered. We assumed a class/group effect when a fixed-class model fitted well. Otherwise we used a random-class model to assess intraclass/group differences. We supplemented the NMAs with pairwise meta-analyses. MAIN RESULTS We included a total of 101,311 participants from 99 studies (26 studies with 32,265 participants in the high-risk population and 73 studies with 69,046 participants in the low-risk population) in our systematic review. The median duration of studies was 52 weeks in the high-risk population and 26 weeks in the low-risk population (range 12 to 156 for both populations). We considered the quality of included studies generally to be good.The NMAs suggested that the LABA/LAMA combination was the highest ranked treatment group to reduce COPD exacerbations followed by LAMA in the both populations.There is evidence that the LABA/LAMA combination decreases moderate to severe exacerbations compared to LABA/ICS combination, LAMA, and LABA in the high-risk population (network hazard ratios (HRs) 0.86 (95% credible interval (CrI) 0.76 to 0.99), 0.87 (95% CrI 0.78 to 0.99), and 0.70 (95% CrI 0.61 to 0.8) respectively), and that LAMA decreases moderate to severe exacerbations compared to LABA in the high- and low-risk populations (network HR 0.80 (95% CrI 0.71 to 0.88) and 0.87 (95% CrI 0.78 to 0.97), respectively). There is evidence that the LABA/LAMA combination reduces severe exacerbations compared to LABA/ICS combination and LABA in the high-risk population (network HR 0.78 (95% CrI 0.64 to 0.93) and 0.64 (95% CrI 0.51 to 0.81), respectively).There was a general trend towards a greater improvement in symptom and quality-of-life scores with the combination therapies compared to monotherapies, and the combination therapies were generally ranked higher than monotherapies.The LABA/ICS combination was the lowest ranked in pneumonia serious adverse events (SAEs) in both populations. There is evidence that the LABA/ICS combination increases the odds of pneumonia compared to LAMA/LABA combination, LAMA and LABA (network ORs: 1.69 (95% CrI 1.20 to 2.44), 1.78 (95% CrI 1.33 to 2.39), and 1.50 (95% CrI 1.17 to 1.92) in the high-risk population and network or pairwise OR: 2.33 (95% CI 1.03 to 5.26), 2.02 (95% CrI 1.16 to 3.72), and 1.93 (95% CrI 1.29 to 3.22) in the low-risk population respectively). There were significant overlaps in the rank statistics in the other safety outcomes including mortality, total, COPD, and cardiac SAEs, and dropouts due to adverse events.None of the differences in lung function met a minimal clinically important difference criterion except for LABA/LAMA combination versus LABA in the high-risk population (network mean difference 0.13 L (95% CrI 0.10 to 0.15). The results of pairwise meta-analyses generally agreed with those of the NMAs. There is no evidence to suggest intraclass/group differences except for lung function at 12 months in the high-risk population. AUTHORS' CONCLUSIONS The LABA/LAMA combination was the highest ranked treatment group to reduce COPD exacerbations although there was some uncertainty in the results. LAMA containing inhalers may have an advantage over those without a LAMA for preventing COPD exacerbations based on the rank statistics. Combination therapies appear more effective than monotherapies for improving symptom and quality-of-life scores. ICS-containing inhalers are associated with an increased risk of pneumonia.Our most comprehensive review including intraclass/group comparisons, free combination therapies, 99 studies, and 20 outcomes for each high- and low-risk population summarises the current literature and could help with updating existing COPD guidelines.

Abstract
Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy. The TOviTO programme has investigated the benefits of treatment with a combination of tiotropium and olodaterol administered via a single inhaler. Tiotropium+olodaterol 5/5 μg significantly improved forced expiratory volume in 1 second (FEV₁) area under the curve from 0 to 3 hours, trough FEV₁ health status and breathlessness versus the mono-components and placebo. Tiotropium+olodaterol 5/5 μg also increased endurance time and reduced dynamic hyperinflation during constant work rate cycle ergometry. On the basis of these and other studies the 2017 GOLD report recommends escalating to dual bronchodilator therapy in patients in groups B and C if they remain symptomatic or continue to have exacerbations and as initial therapy for patients in group D.

Abstract
Background Long-acting bronchodilators are the cornerstone of pharmacologic treatment of COPD. The new combination of long-acting muscarinic antagonist (LAMA) tiotropium (TIO) and long acting beta-agonists (LABA) olodaterol (OLO) has been introduced as fist line therapy for COPD. This article analyses the evidence of efficacy and safety of the TIO/OLO combination. Methods A systematic review and metaanalysis of randomized controlled trials (RCT) with a period of treatment of at least 6 weeks, in patients with COPD confirmed by spirometry, comparing combined treatment with TIO/OLO (approved doses only), with any of the mono-components or any other active comparator administered as an inhalator. Results A total of 10 Randomized controlled trials (RCT) were identified (N = 10,918). TIO/OLO significantly improved trough FEV1 from baseline to week 12 versus TIO, OLO and LABA/ICS (0.06 L, 0.09 L and between 0.04 and 0.05 L, respectively). TIO/OLO improved transitional dyspnea index (TDI) and St. George’s Respiratory Questionnaire (SGRQ) compared with mono-components, with patients more likely to achieve clinically important improvements in TDI (risk ratio [RR]: 1.17, 95% confidence interval [CI]: [1.07, 1.28] versus TIO and RR: 1.14, 95%CI: [1.01, 1.28] versus OLO) and in SGRQ (RR: 1.21, 95%CI: [1.12, 1.30] versus TIO and RR: 1.28, 95%CI: [1.18, 1.40] versus OLO). Patients treated with TIO/OLO showed a significant reduction in the use of rescue medication and no significant differences in frequency of general and serious adverse events were observed between TIO/OLO and mono-components.

Abstract
INTRODUCTION We report the results of the first direct comparison of the once-daily fixed-dose long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) combinations umeclidinium/vilanterol (UMEC/VI) and tiotropium/olodaterol (TIO/OLO) in patients with COPD. METHODS This was a randomized, two-period crossover open-label study in symptomatic patients with COPD [age 40 years or older, postbronchodilator forced expiratory volume in 1 s (FEV1) of 70% or less and 50% or more of predicted normal values, and modified Medical Research Council Dyspnoea Scale score of 2 or greater] not receiving inhaled corticosteroid therapy. Patients were randomized to receive UMEC/VI (62.5/25 µg once daily) via a multidose dry powder inhaler (ELLIPTA) followed by TIO/OLO (5/5 µg once daily) via a soft mist inhaler (Respimat), each for 8 weeks with an interim 3-week washout or vice versa. The primary end point was the change from baseline in trough FEV1 at week 8 with a noninferiority margin of - 50 mL in the per-protocol (PP) population. The incidence of adverse events was also assessed. RESULTS In total, 236 patients (mean age 64.4 years, 60% male) were included in the intent-to-treat population and 227 were included in the PP population. UMEC/VI treatment was noninferior in the PP population and superior in the intent-to-treat population to TIO/OLO treatment with regard to trough FEV1 at week 8 [FEV1 change from baseline 180 mL vs 128 mL; difference 52 mL (95% confidence interval 28-77 mL); p < 0.001]. Patients receiving UMEC/VI had twofold increased odds of experiencing a clinically meaningful increase (100 mL or more) from baseline in trough FEV1 at week 8 compared with patients receiving TIO/OLO (odds ratio 2.05; 95% confidence interval 1.34-3.14). Adverse events occurred in 25% of patients in the UMEC/VI group and in 31% of patients in the TIO/OLO group. CONCLUSION In this first direct comparison of two once-daily fixed-dose LAMA/LABA combinations, superiority was observed for the primary end point of trough FEV1 at week 8 with UMEC/VI compared with TIO/OLO in patients with symptomatic COPD. Both treatments had similar safety profiles. These findings confirm the results of previous indirect LAMA/LABA comparisons, and show that an efficacy gradient exists within the LAMA/LABA class.

Abstract
INTRODUCTION Several dual bronchodilator fixed-dose inhaler medications were recently approved for the treatment of chronic obstructive pulmonary disease (COPD). These products combine a long-acting β2 -agonist (LABA) and long-acting muscarinic antagonist (LAMA). In clinical trials, the separate mechanisms of the bronchodilators resulted in improved lung function. COPD treatment guidelines currently recommend combination LABA/LAMA as alternative therapy to combination LABA/inhaled corticosteroid (ICS). Evidence is limited on the comparative effectiveness of LABA/LAMA and LABA/ICS in COPD. The objective of this study was to compare real-world COPD exacerbation rates among patients treated with LABA/LAMA with those treated with LABA/ICS. METHODS This was a retrospective observational study of COPD patients in the United States treated with LABA/LAMA or LABA/ICS combination. Insurance claims from January 1, 2004, through December 31, 2014, were used as the data source. Patients were required to have greater than one prescription filled for the combination medications, and they were followed from 30 days after drug initiation. Individuals were censored if they discontinued a study medication, initiated medication from the opposite cohort (LAMA or ICS), lost enrollment eligibility, or at the study period end. Exacerbation rates were compared using Poisson regression. RESULTS There were 5384 patients in the LABA/LAMA cohort and 473,388 patients in the LABA/ICS cohort. The LABA/LAMA cohort was older, had more comorbidities, and more severe COPD. Unadjusted annual exacerbation rates were 2.87 events per person-year (standard deviation [SD] 5.14) in the LABA/LAMA cohort and 1.68 (SD 9.82) in the LABA/ICS cohort. The adjusted incidence rate ratio was 0.98 (95% confidence interval 0.95-1.01) for LABA/LAMA compared with LABA/ICS. CONCLUSIONS The LABA/LAMA combination had similar effectiveness to LABA/ICS as measured by exacerbation rates in COPD patients. As a result, characteristics other than effectiveness, such as symptom control, cost, patient preferences, and adverse events, may be important in selecting between the two regimens.

Abstract
In asthma and chronic obstructive pulmonary disease (COPD), an important step in simplifying management and improving adherence with prescribed therapy is to reduce the dose frequency to the minimum necessary to maintain disease control. Fixed-dose combination (FDC) therapy might enhance compliance by decreasing the number of medications and/or the number of daily doses. Furthermore, they have the potential for enhancing, sensitizing, and prolonging the effects of monocomponents. Combination therapy with an inhaled corticosteroid (ICS) and a long-acting β-agonist (LABA) is considered an important approach for treating patients with asthma and patients with severe COPD who have frequent exacerbations. Several ICS/LABA FDCs are now commercially available or will become available within the next few years for the treatment of COPD and/or asthma. Several studies demonstrate that there are a number of added benefits in using combinations of β2-agonists and antimuscarinic agents. In particular, LABA/long-acting antimuscarinic agent (LAMA) combination seems to play an important role in optimizing bronchodilation. Several once-daily and twice-daily LABA/LAMA FDCs have been developed or are in clinical development. LAMA/ICS FDCs seem to be useful in COPD and mainly in asthma, in patients with severe asthma and persistent airflow limitation. The rationale behind the ICS/LABA/LAMA FDCs seems logical because all three agents work via different mechanisms on different targets, potentially allowing for lower doses of the individual agents to be used, accompanied by improved side effect profiles. In effect, in clinical practice, concomitant use of all three compounds is common, especially in more severe COPD but also in the treatment of adults with poorly controlled asthma despite maintenance treatment with high-dose ICS and a LABA.

Abstract
Parasympathetic activity is increased in patients with chronic obstructive pulmonary disease (COPD) and asthma and appears to be the major reversible component of airway obstruction. Therefore, treatment with muscarinic receptor antagonists is an effective bronchodilator therapy in COPD and also in asthmatic patients. In recent years, the accumulating evidence that the cholinergic system controls not only contraction by airway smooth muscle but also the functions of inflammatory cells and airway epithelial cells has suggested that muscarinic receptor antagonists could exert other effects that may be of clinical relevance when we must treat a patient suffering from COPD or asthma. There are currently six muscarinic receptor antagonists licenced for use in the treatment of COPD, the short-acting muscarinic receptor antagonists (SAMAs) ipratropium bromide and oxitropium bromide and the long-acting muscarinic receptor antagonists (LAMAs) aclidinium bromide, tiotropium bromide, glycopyrronium bromide and umeclidinium bromide. Concerns have been raised about possible associations of muscarinic receptor antagonists with cardiovascular safety, but the most advanced compounds seem to have an improved safety profile. Further beneficial effects of SAMAs and LAMAs are seen when added to existing treatments, including LABAs, inhaled corticosteroids and phosphodiesterase 4 inhibitors. The importance of tiotropium bromide in the maintenance treatment of COPD, and likely in asthma, has spurred further research to identify new LAMAs. There are a number of molecules that are being identified, but only few have reached the clinical development.

Abstract
Inhaled bronchodilator medications are central to the management of COPD and are frequently given on a regular basis to prevent or reduce symptoms. While short-acting bronchodilators are a treatment option for people with relatively few COPD symptoms and at low risk of exacerbations, for the majority of patients with significant breathlessness at the time of diagnosis, long-acting bronchodilators may be required. Dual bronchodilation with a long-acting β2-agonist and long-acting muscarinic antagonist may be more effective treatment for some of these patients, with the aim of improving symptoms. This combination may also reduce the rate of exacerbations compared with a bronchodilator-inhaled corticosteroid combination in those with a history of exacerbations. However, there is currently a lack of guidance on clinical indicators suggesting which patients should step up from mono- to dual bronchodilation. In this article, we discuss a number of clinical indicators that could prompt a patient and physician to consider treatment escalation, while being mindful of the need to avoid unnecessary polypharmacy. These indicators include insufficient symptomatic response, a sustained increased requirement for rescue medication, suboptimal 24-hour symptom control, deteriorating symptoms, the occurrence of exacerbations, COPD-related hospitalization, and reductions in lung function. Future research is required to provide a better understanding of the optimal timing and benefits of treatment escalation and to identify the appropriate tools to inform this decision.

Abstract
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.

The effect of tiotropium in combination with olodaterol on house dust mite-induced allergic airway disease. Pulm Pharmacol Ther 2017; 45:210-217.

Abstract
One of the major goals of asthma therapy is to maintain asthma control and prevent acute exacerbations. Long-acting bronchodilators are regularly used for the treatment of asthma patients and in clinical studies the anti-cholinergic tiotropium has recently been shown to reduce exacerbations in patients with asthma. So far it is unclear how tiotropium exerts this effect. For this purpose, we designed an allergen-driven rechallenge model of allergic airway inflammation in mice, to assess the effectiveness of tiotropium and the long-acting β-2 adrenoceptor agonist olodaterol on allergen-induced exacerbations of airway disease. Female C57BL/6J mice were sensitized intranasally (i.n.) with 1 μg of house dust mite (HDM) extract followed by a challenge regime (5 consecutive days 10 μg HDM extract i.n.) after one week. Mice were exposed to a secondary challenge five weeks after sensitization and were treated i.n. with different concentrations of tiotropium or olodaterol (1, 10 and 100 μg/kg) or a combination thereof (10 μg/kg each) prior to and during the secondary challenge period. Three days after the last challenge, bronchoalveolar lavage (BAL) fluid and lung tissue were collected for flow cytometry and histologic analysis, respectively. Secondary challenge with HDM extract strongly induced allergic airway disease reflected by inflammatory cell infiltration and goblet cell metaplasia. Treatment with tiotropium, but not with olodaterol reduced tissue inflammation and goblet cell metaplasia in a dose-dependent manner. The combination of tiotropium and olodaterol was more effective in significantly reducing tissue inflammation compared to tiotropium treatment alone, and also led to a decrease in BAL cell counts. These data suggest that in a model of relapsing allergic airway disease tiotropium directly prevents exacerbations by reducing inflammation and mucus production in the airways. In addition, the combination of tiotropium and olodaterol exerts synergistic effects.

Abstract
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.

Abstract
When there are no randomised clinical trials directly comparing all relevant treatment options, an indirect treatment comparison via meta-analysis of the available clinical evidence is an acceptable alternative. However, meta-analyses may be very misleading if not adequately performed. Here, we propose and validate a simple and effective approach to meta-analysis for exploring the effectiveness of long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combinations in chronic obstructive pulmonary disease.14 articles with 20 329 patients (combinations n=9292; monocomponents n=11 037) were included in this study. LABA/LAMA combinations were always more effective than the monocomponents in terms of the improvement in trough forced expiratory volume in 1 s, transition dyspnoea index and St George's Respiratory Questionnaire scores after 3, 6 and 12 months of treatment. No significant publication bias was identified. Significant discrepancies with previous network meta-analyses have been found, with overall differences ranging from 26.7% to 43.3%.Results from previous network meta-analyses were misleading because no adequate attention was given to formulating the review question, specifying eligibility criteria, correctly identifying studies, collecting appropriate information and deciding what it would be pharmacologically relevant to analyse. The real gradient of effectiveness of LABA/LAMA fixed-dose combinations remains an unmet medical need; however, it can be investigated indirectly using a high-quality meta-analytic approach.

Abstract
AIMS Olodaterol is a novel inhaled long-acting β2 -agonist (LABA) that showed efficacy as a bronchodilator for patients with chronic obstructive pulmonary disease (COPD) and asthma. However, it is unclear whether olodaterol reduces mortality; the safety issues of olodaterol have not been fully evaluated. METHODS Randomized controlled trials comparing olodaterol with placebo for patients with COPD or asthma, which evaluated mortality or serious adverse events, were included. Eighteen trials reporting mortality and 26 trials reporting nonfatal serious adverse events were included. RESULTS Inhaled olodaterol did not reduce the risk of mortality (Peto fixed OR 1.31; 95% CI 0.90-1.89) and had no significant impacts on nonfatal serious adverse events (Peto fixed OR 1.03; 95% CI 0.91-1.15). CONCLUSIONS Inhaled olodaterol has no impact on mortality risk in clinical trials conducted on patients with COPD and asthma. However, the interpretation is limited by a high OR (1.31) and a wide CI that includes the hazardous effect. We could not find any relationship between inhaled olodaterol use and nonfatal serious adverse events.

Abstract
Tiotropium-olodaterol, formulated in the Respimat soft-mist inhaler, is an inhaled fixed-dose combination (FDC) of a long-acting muscarinic antagonist (LAMA) and a long-acting β2-agonist (LABA), commercialized under the name of Spiolto or Stiolto. The efficacy of tiotropium-olodaterol 5-5 μg once daily in adult patients with COPD was documented in eleven large, multicenter trials of up to 52 weeks duration. Tiotropium-olodaterol 5-5 μg not only improved spirometric values to a significantly greater extent than placebo but also resulted in statistically significant beneficial effects on dyspnea, markers of hyperinflation, use of rescue medication, health-related quality of life, and exercise endurance. Improvements exceeded the minimal clinically important difference (MCID) for forced expiratory volume in 1 second (FEV1), dyspnea, and quality of life. Differences between tiotropium-olodaterol 5-5 μg and the respective monocomponents were statistically significant for FEV1, dyspnea, markers of hyperinflation, use of rescue medication, and health-related quality of life, but did not reach the MCID. However, dual bronchodilatation significantly increased the number of patients who exceeded the MCID for dyspnea and quality of life. Moreover, tiotropium-olodaterol 5-5 μg was significantly more effective than salmeterol-fluticasone (FDC) twice daily at improving pulmonary function. Differences between tiotropium-olodaterol and other LAMA/LABA FDCs were not observed for FEV1 or other efficacy markers. Therefore, tiotropium-olodaterol is a valuable option in the treatment of COPD patients who remain symptomatic under monotherapy.

Abstract
Long-acting muscarinic antagonist (LAMA) or long-acting β2-agonist (LABA) bronchodilators and their combination are recommended for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Although the efficacy of LAMAs and LABAs has been well established through randomized controlled trials (RCTs), questions remain regarding their cardiovascular (CV) safety. Furthermore, while the safety of LAMA and LABA monotherapy has been extensively studied, data are lacking for LAMA/LABA combination therapy, and the majority of the studies that have reported on the CV safety of LAMA/LABA combination therapy were not specifically designed to assess this. Evaluation of CV safety for COPD treatments is important because many patients with COPD have underlying CV comorbidities. However, severe CV and other comorbidities are often exclusion criteria for RCTs, contributing to a lack in external validity and generalizability. Real-world observational studies are another important tool to evaluate the effectiveness and safety of COPD therapies in a broader population of patients and can improve upon the external validity limitations of RCTs. We examine what is already known regarding the CV and cerebrovascular safety of LAMA/LABA combination therapy from RCTs and real-world observational studies, and explore the advantages and limitations of data derived from each study type. We also describe an ongoing prospective, observational, comparative post-authorization safety study of a LAMA/LABA combination therapy (umeclidinium/vilanterol) and LAMA monotherapy (umeclidinium) versus tiotropium, with a focus on the relative merits of the study design.

Abstract
Current guidelines recommend inhaled pharmacologic therapy as the preferred route of administration for treating COPD. Bronchodilators (β2-agonists and antimuscarinics) are the mainstay of pharmacologic therapy in patients with COPD, with long-acting agents recommended for patients with moderate to severe symptoms or those who are at a higher risk for COPD exacerbations. Dry powder inhalers and pressurized metered dose inhalers are the most commonly used drug delivery devices, but they may be inadequate in various clinical scenarios (eg, the elderly, the cognitively impaired, and hospitalized patients). As more drugs become available in solution formulations, patients with COPD and their caregivers are becoming increasingly satisfied with nebulized drug delivery, which provides benefits similar to drugs delivered by handheld inhalers in both symptom relief and improved quality of life. This article reviews recent innovations in nebulized drug delivery and the important role of nebulized therapy in the treatment of COPD.

Abstract
Purpose The fixed-dose dual bronchodilator combination (FDC) of tiotropium and olodaterol showed increased effectiveness regarding lung function and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD) compared with the use of its mono-components. Yet, while effectiveness and safety have been shown, the health economic implication of this treatment is still unknown. The aim of this study was to assess the cost–utility and budget impact of tiotropium–olodaterol FDC in patients with moderate to very severe COPD in the Netherlands. Patients and methods A cost–utility study was performed, using an individual-level Markov model. To populate the model, individual patient-level data (age, height, sex, COPD duration, baseline forced expiratory volume in 1 second) were obtained from the tiotropium–olodaterol TOnado trial. In the model, forced expiratory volume in 1 second and patient-level data were extrapolated to utility and survival, and treatment with tiotropium–olodaterol FDC was compared with tiotropium. Cost–utility analysis was performed from the Dutch health care payer’s perspective using a 15-year time horizon in the base-case analysis. The standard Dutch discount rates were applied (costs: 4.0%; effects: 1.5%). Both univariate and probabilistic sensitivity analyses were performed. Budget impact was annually assessed over a 5-year time horizon, taking into account different levels of medication adherence. Results As a result of cost increases, combined with quality-adjusted life-year (QALY) gains, results showed that tiotropium–olodaterol FDC had an incremental cost-effectiveness ratio of €7,004/QALY. Without discounting, the incremental cost-effectiveness ratio was €5,981/QALY. Results were robust in univariate and probabilistic sensitivity analyses. Budget impact was estimated at €4.3 million over 5 years assuming 100% medication adherence. Scenarios with 40%, 60%, and 80% adherence resulted in lower 5-year incremental cost increases of €1.7, €2.6, and €3.4 million, respectively. Conclusion Tiotropium–olodaterol FDC can be considered a cost-effective treatment under current Dutch cost-effectiveness thresholds.

Abstract
PURPOSE Published data on the pharmacology, pharmacokinetics, efficacy, and safety of the once-daily, long-acting β2-agonist (LABA) olodaterol are reviewed. SUMMARY Olodaterol (Striverdi Respimat, Boehringer Ingelheim), a LABA with high selectivity for β2-adrenergic receptors, is indicated for the treatment of chronic obstructive pulmonary disease (COPD); the recommended dose is 5 μg, to be delivered once daily via the Respimat inhaler. In 48- and 6-week Phase III clinical trials of olodaterol evaluating various lung function and symptomatic outcomes in patients with moderate to very severe COPD, olodaterol use was associated with significant improvements in spirometry outcomes, such as postbronchodilator forced expiratory volume in one second (FEV1), as well as dyspnea severity and quality-of-life measures. Other clinical trials demonstrated that olodaterol produced beneficial effects on FEV1 measures throughout the 24-hour dosing interval. A meta-analysis of data from 20 published research reports indicated that olodaterol's efficacy was comparable to that of the once-daily LABA indacaterol and that the combination of olodaterol and tiotropium provided improvements in lung function greater than those provided by tiotropium alone. Analysis of pooled data from four long-term trials showed that olodaterol's safety profile was comparable to that of formoterol; the most frequently reported adverse effects associated with olodaterol use were bronchitis, nasopharyngitis, and upper respiratory tract infection. CONCLUSION Once-daily olodaterol 5 μg is an effective therapy in improving lung function and symptomatic outcomes in patients with moderate to very severe COPD receiving other maintenance therapy, with a satisfactory safety profile.

Abstract
Background Maintaining and improving physical functioning is key to mitigating the cycle of deconditioning associated with chronic obstructive pulmonary disease (COPD). We evaluated the impact of free combination of the long-acting anticholinergic tiotropium plus the long-acting β2-agonist olodaterol on physical functioning in a real-world clinical setting. Methods In this open-label noninterventional study, Global initiative for chronic Obstructive Lung Disease (GOLD) B–D patients with COPD aged ≥40 years were treated for 4–6 weeks with either tiotropium 5 μg + olodaterol 5 μg (both via Respimat® inhaler) or tiotropium 18 μg (HandiHaler®) + olodaterol 5 μg (Respimat®) once daily. Physical functioning was assessed by the self-reported 10-item Physical Functioning Questionnaire (PF-10). The primary end point was the percentage of patients achieving therapeutic success, defined as a 10-point increase in the PF-10 between baseline (visit 1) and weeks 4–6 (visit 2). Secondary end points included absolute PF-10 scores, Physicians’ Global Evaluation, satisfaction with Respimat® and adverse events. Results A total of 1,858 patients were treated: 1,298 (69.9%) with tiotropium 5 μg + olodaterol 5 μg and 560 (30.1%) with tiotropium 18 μg + olodaterol 5 μg. At study end, 1,683 (92.6%) and 1,556 patients (85.6%) continued using tiotropium and olodaterol, respectively; 48.9% (95% confidence interval: 46.5, 51.3) achieved the primary end point. Therapeutic success rates were significantly higher for maintenance-naïve patients compared to those who had received prior therapy (59.1% vs 44.5%; P<0.0001), largely driven by maintenance-treatment-naïve GOLD B (59.8%) and C (63.0%) patients. Absolute physical functioning scores increased from an average baseline of 44.0 (standard deviation: 25.2) to 54.2 (standard deviation: 26.9) at visit 2. Patients’ general condition improved from baseline to visit 2, and patients were largely satisfied with the Respimat® inhaler. Adverse events were reported by 7.5% of patients; the most common were respiratory in nature. Conclusion Tiotropium + olodaterol improved physical functioning within 4–6 weeks in patients with moderate-to-very severe COPD. GOLD B and C patients with no prior maintenance treatment demonstrated the greatest benefit.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major cause of death and disability worldwide. Inhaled bronchodilators are the mainstay of COPD pharmacological treatment. Long-acting muscarinic antagonists (LAMAs) are a major class of inhaled bronchodilators. Some LAMA/device systems with different characteristics and dosing schedules are currently approved for maintenance therapy of COPD and a range of other products are being developed. They improve lung function and patient-reported outcomes and reduce acute bronchial exacerbations with good safety. LAMAs are used either alone or associated with long-acting β₂-agonists, eventually in fixed dose combinations. Long-acting β₂-agonist/LAMA combinations assure additional benefits over the individual components alone. The reader will obtain a view of the safety and efficacy of the different LAMA/device systems in COPD patients.

Abstract
β2-agonists were introduced in the 1940s as bronchodilators to be used in obstructive respiratory diseases. Long-acting β2-agonists have been a mainstay of bronchodilating treatment for decades. Recently, agents extending their effect to 24 hours and thus allowing the once-daily administration were introduced, defined as very-long-acting β2-agonists. Olodaterol is a new very-long-acting β2-agonist that has been shown, in controlled trials, to improve lung function as well as clinical outcomes and quality of life. Most of these trials included patients with moderate, severe, or very severe chronic obstructive pulmonary disease (COPD). Olodaterol has a rapid onset of action (comparable to formoterol) and provides bronchodilation over 24 hours. In controlled trials, olodaterol was shown to be as effective as formoterol twice daily, but significantly superior in terms of quality of life in patients with COPD. The safety profile of olodaterol was very good, with a rate of adverse events, including the cardiac events that are particularly important for β2-agonists, comparable to placebo. Also, the efficiency of the Respimat(®) device concurs to the effectiveness of treatment.

Abstract
Current guidelines differ slightly on the recommendations for treatment of Chronic Obstructive Pulmonary Disease (COPD) patients, and although there are some undisputed recommendations, there is still debate regarding the management of COPD. One of the hindrances to deciding which therapeutic approach to choose is late diagnosis or misdiagnosis of COPD. After a proper diagnosis is achieved and severity assessed, the choice between a stepwise or "hit hard" approach has to be made. For GOLD A patients the stepwise approach is recommended, whilst for B, C and D patients this remains debatable. Moreover, in patients for whom inhaled corticosteroids (ICS) are recommended, a step-up or "hit hard" approach with triple therapy will depend on the patient's characteristics and, for patients who are being over-treated with ICS, ICS withdrawal should be performed, in order to optimize therapy and reduce excessive medications. This paper discusses and proposes stepwise, "hit hard", step-up and ICS withdrawal therapeutic approaches for COPD patients based on their GOLD group. We conclude that all approaches have benefits, and only a careful patient selection will determine which approach is better, and which patients will benefit the most from each approach.

Abstract
The quality of care can be improved by the development and implementation of evidence-based treatment guidelines. Different national guidelines for chronic obstructive pulmonary disease (COPD) exist in Europe and relevant differences may exist among them.This was an evaluation of COPD treatment guidelines published in Europe and Russia in the past 7 years. Each guideline was reviewed in detail and information about the most important aspects of patient diagnosis, risk stratification and pharmacotherapy was extracted following a standardised process. Guidelines were available from the Czech Republic, England and Wales, Finland, France, Germany, Italy, Poland, Portugal, Russia, Spain and Sweden. The treatment goals, criteria for COPD diagnosis, consideration of comorbidities in treatment selection and support for use of long-acting bronchodilators, were similar across treatment guidelines. There were differences in measures used for stratification of disease severity, consideration of patient phenotypes, criteria for the use of inhaled corticosteroids and recommendations for other medications (e.g. theophylline and mucolytics) in addition to bronchodilators.There is generally good agreement on treatment goals, criteria for diagnosis of COPD and use of long-acting bronchodilators as the cornerstone of treatment among guidelines for COPD management in Europe and Russia. However, there are differences in the definitions of patient subgroups and other recommended treatments.

Abstract
Chronic obstructive pulmonary disease (COPD), a respiratory disease characterized by a progressive decline in lung function, is considered to be a leading cause of morbidity and mortality. Long-acting inhaled bronchodilators, such as long-acting β2 agonists (LABAs) or long-acting muscarinic antagonists (LAMAs), are the cornerstone of maintenance therapy for patients with moderate-to-very-severe COPD. For patients not sufficiently controlled on a single long-acting bronchodilator, a combination of different bronchodilators has shown a significant increase in lung function. Tiotropium, a once-daily dosing LAMA, demonstrated sustained improvements in lung function as well as improved health-related quality of life, reduced exacerbations, and increased survival without altering the rate of decline in the mean forced expiratory volume in 1 second (FEV1) with fairly tolerable side effects. Olodaterol is a once-daily dosing LABA that has proven to be effective in improving lung function, reducing rescue medication use, and improving dyspnea and health-related quality of life, as well as improving exercise endurance with an acceptable safety profile. The combination of olodaterol and tiotropium provided additional improvements in lung function greater than monotherapy with each drug alone. Several well-designed randomized trials confirmed that the synergistic effect of both drugs in combination was able to improve lung function and health-related quality of life without a significant increase in adverse effects. The objective of this paper is to review available evidence on the clinical efficacy and safety of tiotropium, olodaterol, and their combination in patients with COPD.

Abstract
BACKGROUND Long-acting bronchodilators, comprising long-acting beta2-agonists (LABA) and long-acting anti-muscarinic agents (LAMA, principally tiotropium), are commonly used for managing persistent symptoms of chronic obstructive pulmonary disease (COPD). Combining these treatments, which have different mechanisms of action, may be more effective than the individual components. However, the benefits and risks of combining tiotropium and LABAs for the treatment of COPD are unclear. OBJECTIVES To compare the relative effects on markers of quality of life, exacerbations, symptoms, lung function and serious adverse events in people with COPD randomised to LABA plus tiotropium versus tiotropium alone; or LABA plus tiotropium versus LABA alone. SEARCH METHODS We searched the Cochrane Airways Group Specialised Register of trials and ClinicalTrials.gov up to July 2015. SELECTION CRITERIA We included parallel-group, randomised controlled trials of three months or longer comparing treatment with tiotropium in addition to LABA against tiotropium or LABA alone for people with COPD. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and then extracted data on trial quality and the outcome results. We contacted study authors for additional information. We collected information on adverse effects from the trials. MAIN RESULTS This review included 10 trials on 10,894 participants, mostly recruiting participants with moderate or severe COPD. All of the trials compared tiotropium in addition to LABA to tiotropium alone, and four trials additionally compared LAMA plus LABA with LABA alone. Four studies used the LABA olodaterol, three used indacaterol, two used formoterol, and one used salmeterol.Compared to tiotropium alone, treatment with tiotropium plus LABA resulted in a slightly larger improvement in mean health-related quality of life (St George's Respiratory Questionnaire (SGRQ) (mean difference (MD) -1.34, 95% confidence interval (CI) -1.87 to -0.80; 6709 participants; 5 studies). The MD was smaller than the four units that is considered clinically important, but a responder analysis indicated that 7% more participants receiving tiotropium plus LABA had a noticeable benefit (greater than four units) from treatment in comparison to tiotropium alone. In the control arm in one study, which was tiotropium alone, the SGRQ improved by falling 4.5 units from baseline and with tiotropium plus LABA the improvement was a fall of a further 1.3 units (on average). Most of the data came from studies using olodaterol. High withdrawal rates in the trials increased the uncertainty in this result, and the GRADE assessment for this outcome was therefore moderate. There were no significant differences in the other primary outcomes (hospital admission or mortality).The secondary outcome of pre-bronchodilator forced expiratory volume in one second (FEV1) showed a small mean increase with the addition of LABA over the control arm (MD 0.06, 95% CI 0.05 to 0.07; 9573 participants; 10 studies), which showed a change from baseline ranging from 0.03 L to 0.13 L with tiotropium alone. None of the other secondary outcomes (exacerbations, symptom scores, serious adverse events, and withdrawals) showed any statistically significant differences between the groups. There was moderate heterogeneity for both exacerbations and withdrawals.This review included data on four LABAs: two administered twice daily (salmeterol, formoterol) and two once daily (indacaterol, olodaterol). The results were largely from studies of olodaterol and there was insufficient information to assess whether the other LABAs were equivalent to olodaterol or each other.Comparing LABA plus tiotropium treatment with LABA alone, there was a small but significant improvement in SGRQ (MD -1.25, 95% CI -2.14 to -0.37; 3378 participants; 4 studies). The data came mostly from studies using olodaterol and, although the difference was smaller than four units, this still represented an increase of 10 people with a clinically important improvement for 100 treated. There was also an improvement in FEV1 (MD 0.07, 95% CI 0.06 to 0.09; 3513 participants; 4 studies), and in addition an improvement in exacerbation rates (odds ratio (OR) 0.80, 95% CI 0.69 to 0.93; 3514 participants; 3 studies). AUTHORS' CONCLUSIONS The results from this review indicated a small mean improvement in health-related quality of life and FEV1 for participants on a combination of tiotropium and LABA compared to either agent alone, and this translated into a small increase in the number of responders on combination treatment. In addition, adding tiotropium to LABA reduced exacerbations, although adding LABA to tiotropium did not. Hospital admission and mortality were not altered by adding LABA to tiotropium, although there may not be enough data. While it is possible that this is affected by higher attrition in the tiotropium group, one would expect that participants withdrawn from the study would have had less favourable outcomes; this means that the expected direction of attrition bias would be to reduce the estimated benefit of the combination treatment. The results were largely from studies of olodaterol and there was insufficient information to assess whether the other LABAs were equivalent to olodaterol or each other.

Abstract
Bronchodilators are the most important drugs used for the treatment of chronic obstructive pulmonary disease (COPD). In particular, these therapeutic agents are mostly long-acting compounds utilized via inhalation, and include LAMA (long-acting muscarinic receptor antagonists) and LABA (long-acting β2-adrenoceptor agonists). Because LAMA and LABA induce bronchodilation by distinct mechanisms of action, LABA/LAMA combinations provide a reciprocal potentiation of the pharmacological effects caused by each component. Hence, many COPD patients who do not achieve a satisfactory control of their symptoms using a single, either LAMA or LABA bronchodilator, can experience relevant benefits with the use of LAMA/LABA fixed combinations. Many different LAMA/LABA combinations have been recently developed and evaluated in randomized clinical trials. In this context, our review focuses on the pharmacological mechanisms underpinning the bronchodilation elicited by the LAMA tiotropium bromide and the LABA olodaterol. We also discuss the results of the most important clinical studies carried out in COPD patients to assess the efficacy and safety of tiotropium/olodaterol combinations.

Abstract
Background Combination of the inhaled long-acting muscarinic antagonist umeclidinium (UMEC; GSK573719) with the long-acting β2-agonist vilanterol (VI) is an approved maintenance treatment for COPD in the US and EU. We compared the efficacy and safety of UMEC/VI with placebo in patients with COPD of Asian ancestry. Patients and methods In this 24-week, Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study, patients were randomized 1:1:1 to UMEC/VI 125/25 μg, UMEC/VI 62.5/25 μg, or placebo. The primary efficacy end point was trough forced expiratory volume in 1 second (FEV1) on day 169; secondary end points were Transition Dyspnea Index (TDI) focal score at week 24 and weighted mean (WM) FEV1 over 0–6 hours postdose on day 1. Additional end points and safety were also assessed. Results Both UMEC/VI 125/25 μg and UMEC/VI 62.5/25 μg statistically significantly improved trough FEV1 at day 169 versus placebo (UMEC/VI 125/25 μg, 0.216 L, [95% confidence interval [CI] 0.175–0.257]; UMEC/VI 62.5/25 μg, 0.151 L, 95% CI 0.110–0.191; both P<0.001). Statistically significant improvements in TDI score were observed for both UMEC/VI groups versus placebo (UMEC/VI 125/25 μg, 0.9, 95% CI 0.3–1.4, P=0.002; UMEC/VI 62.5/25 μg, 0.7, 95% CI 0.1–1.2, P=0.016). On day 1, both UMEC/VI groups improved 0–6-hour WM FEV1 versus placebo (UMEC/VI 125/25 μg, 0.182 L 95% CI 0.161–0.203; UMEC/VI 62.5/25 μg, 0.160 L, 95% CI 0.139–0.181; both P<0.001). Statistically significant improvements for UMEC/VI groups versus placebo were observed for rescue albuterol use at weeks 1–24 (puffs/day, both P<0.001). The incidence of adverse events was similar across groups. Conclusion In Asian patients with COPD, once-daily UMEC/VI 125/25 μg and UMEC 62.5/25 μg resulted in clinically meaningful and statistically significant improvements in lung-function end points versus placebo. Symptomatic and quality of life measures also improved. The safety profile of UMEC/VI was consistent with previous studies.

Abstract
The most widely used maintenance therapies in chronic obstructive pulmonary disease (COPD) are long-acting muscarinic antagonists (LAMAs), and a number of these drugs are now available in combination with long-acting β2-agonists (LABAs). LAMAs inhibit the parasympathetic muscarinic pathway, while LABAs, as sympathomimetics, reduce airway smooth muscle (ASM) tone. As well as directly controlling the constriction and relaxation of ASM, muscarinic and adrenergic receptors are found on inflammatory cells, and drugs that target these receptors may also reduce inflammation in COPD. Evidence suggests that the muscarinic and adrenergic pathways cross-talk at the level of neuronal input to the ASM via second-messenger pathways within ASM cells. Although the cross-talk is not completely understood, pharmacologically targeting both pathways in COPD can maximize bronchodilation. Combining LAMAs and LABAs demonstrated improved efficacy compared with the individual therapies and so, for greater convenience, several fixed-dose combinations for once-daily use have been developed. These fixed-dose combinations demonstrate improvements in both lung-function and patient-reported outcomes compared with well-established monotherapies, with similar tolerability profiles to the individual agents.
