Abstract
BACKGROUND Although clinical trials including asthma and COPD patients have revealed much about exacerbation frequencies, most studies are limited in that they recruited patients only with a clear diagnosis of one disease or the other, based on conventional diagnostic criteria, which may exclude many real-world patients with mixed symptoms. METHODS NOVELTY is a global prospective observational study of patients with asthma and/or COPD from real-world practice. In this subanalysis, we compared patient characteristics of obstructive pulmonary diseases between the Japanese population (n = 820) and the overall population excluding Japanese patients (n = 10,406). RESULTS The Japanese population had fewer exacerbations than the overall population across most of the physician-assessed disease severities and all diagnoses. The difference in exacerbation frequencies was more prominent in patients with COPD and asthma + COPD. The Japanese population was older, had higher former smoking rates, lower BMI, fewer respiratory symptoms, and better health-related quality of life compared with the overall population across all diagnoses. CONCLUSIONS We clarified differences in patient characteristics among patients with asthma and/or COPD in Japan compared with non-Japanese patients. Importantly, we found that Japanese patients with asthma and/or COPD had significantly fewer exacerbations compared with patients overall. The results from our study may contribute to the development of precision medicine and guidelines specific to Japan.

Abstract
Chronic obstructive pulmonary disease (COPD) and asthma are the most common chronic airway diseases and are characterized by chronic airway inflammation and airflow limitation. Japanese patients with COPD or asthma have characteristics different from those of Westerners. Therefore, understanding the characteristics and clinical course of Japanese patients with COPD and those with asthma, particularly severe asthma, is critical for their management and appropriate treatment. The Hokkaido COPD cohort and Hokkaido-based Investigative Cohort Analysis for Refractory Asthma (Hi-CARAT) are high-quality cohort studies of COPD and asthma in the Japanese population and provide valuable data. This report summarizes the clinical findings from the two cohort studies and provides data for more appropriate management of Japanese patients with COPD and/or asthma. Overall, 279 patients with COPD were followed up for up to 10 years in the Hokkaido COPD cohort study, and 127 with severe asthma were followed up for up to 6 years in the Hi-CARAT study. Seventy-nine patients with mild-to-moderate asthma provided baseline data for the Hi-CARAT study. In each disease, several distinct factors, including systemic status and non-pulmonary factors, were associated with important clinical outcomes, such as lung function decline, exacerbations, impaired quality of life, and mortality. Therefore, multifaceted evaluation based on the characteristics of the Japanese population is necessary for the management of COPD and asthma.

Abstract
Purpose Low body mass index (BMI) has been reported to be associated with poor prognosis in patients with chronic obstructive pulmonary disease (COPD). In contrast, a detailed analysis of the association between body weight change over time and prognosis is not sufficient, particularly in Japanese patients with COPD who have been reported to be much thinner compared to Westerners. This study aimed to investigate the relationship between annual body weight change and long-term prognosis in Japanese patients with COPD in two independent cohorts. Patients and Methods We analyzed 279 patients with COPD who participated in the Hokkaido COPD cohort study as a discovery cohort. We divided participants into three groups according to quartiles of annual body weight change calculated by the data from the first 5 years: weight loss group (<-0.17 kg/year), no change group (−0.17 to ≤0.20 kg/year), and weight gain group (>0.20 kg/year). The association between annual body weight change and prognosis was replicated in the Kyoto University cohort (n = 247). Results In the Hokkaido COPD cohort study, the weight loss group had significantly worse mortality than the other groups, whereas there was no difference in BMI at baseline. In the multivariate analysis, annual body weight change was an independent risk factor for all-cause mortality, which was confirmed in the Kyoto University cohort. Conclusion Annual body weight loss is associated with poor prognosis in Japanese patients with COPD, independent of baseline BMI. Longitudinal assessment of body weight is important for the management of COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) may coexist with lung cancer, but the impact on prognosis is uncertain. Moreover, it is unclear whether pharmacological treatment for COPD improves the patient's prognosis. We retrospectively investigated patients with advanced non-small-cell lung cancer (NSCLC) who had received chemotherapy at Kyoto University Hospital. Coexisting COPD was diagnosed by spirometry, and the association between pharmacological treatment for COPD and overall survival (OS) was assessed. Of the 550 patients who underwent chemotherapy for advanced NSCLC between 2007 and 2014, 347 patients who underwent spirometry were analyzed. Coexisting COPD was revealed in 103 patients (COPD group). The median OS was shorter in the COPD group than the non-COPD group (10.6 vs. 16.8 months). Thirty-seven patients had received COPD treatment, and they had a significantly longer median OS than those without treatment (16.7 vs. 8.2 months). Multivariate Cox regression analysis confirmed the positive prognostic impact of COPD treatment. Additional validation analysis revealed similar results in patients treated with immune checkpoint inhibitors (ICIs). Coexisting COPD had a significant association with poor prognosis in advanced NSCLC patients if they did not have pharmacological treatment for COPD. Treatment for coexisting COPD has the potential to salvage the prognosis.

Abstract
BACKGROUND Dyspnea is a common symptom in patients with COPD. It causes physical inactivity and impaired health-related quality of life. Although optimal breathing methods alleviate dyspnea, it is unclear whether breathing instability has a clinical impact on patients with COPD. This study aimed to investigate whether resting breathing instability during wakefulness was associated with dyspnea assessed by the modified Medical Research Council (mMRC) dsypnea scale and whether breathing instability can be a novel predictor of clinical outcomes. METHODS Forty-four subjects with stable COPD were enrolled (mean age, 71.0 y). Resting breathing was monitored for 15 min by using respiratory inductance plethysmography. Breathing instability was evaluated with the coefficient of variation for breath-by-breath respiratory duration and tidal volume ([Formula: see text]) by using an artifact-free respiratory signal for 5 min. Pulmonary function testing and blood gas analysis were performed (mean FEV1 percent of predicted, 68.5%). Questionnaires with regard to dyspnea and health-related quality of life were also completed. Exacerbations were recorded prospectively for 1 year after the initial assessment. RESULTS The coefficients of variation for [Formula: see text] were significantly higher in the subjects with an mMRC dyspnea scale score ≥ 2 versus those with an mMRC dyspnea scale score < 2 (26.4 ± 7.4% vs 20.3 ± 6.4%, P = .006) . The coefficients of variation for respiratory duration and VT were not associated with age, body mass index, and pulmonary function variables. In multivariate analysis, FEV1 percent of predicted and coefficient of variation for [Formula: see text] remained significant predictors for an mMRC dyspnea scale score ≥ 2 (P = .004 and P = .01, respectively). Coefficient of variation values were also correlated with several health-related quality of life domains. The exacerbation frequency was associated with the coefficient of variation for [Formula: see text]. CONCLUSIONS Resting breathing pattern during wakefulness is a novel assessment tool for severity of dyspnea, which can be one of the predictors for exacerbation in patients with COPD.

Real-world effectiveness of early intervention with fixed-dose tiotropium/olodaterol vs tiotropium in Japanese patients with COPD: a high-dimensional propensity score-matched cohort analysis. Respir Res 2021; 22:180.

Abstract
Background Escalation to triple therapy (long-acting muscarinic antagonist/β2-agonist, inhaled corticosteroid [ICS]) in chronic obstructive pulmonary disorder (COPD) is recommended for patients on LAMA/LABA combinations with frequent exacerbations and severe symptoms. An extended time-to-escalation to triple therapy suggests patients are in a stable condition and is an indicator of treatment effectiveness. No studies in Japanese clinical practice have compared the effectiveness of LAMA/LABA fixed-dose combination therapies with LAMA monotherapy in terms of time-to-escalation to triple therapy. The primary objective of this real-world study in Japan was to compare time-to-escalation to triple therapy among new users of tiotropium/olodaterol or tiotropium monotherapy for COPD without asthma. Methods In this active-comparator cohort study, new users of tiotropium/olodaterol (n = 1436) and tiotropium monotherapy (n = 5352) were identified from a large Japanese hospital-based database (Medical Data Vision Co., Ltd., Tokyo; prespecified study period: 1 April 2015 to 31 March 2019); patients in each group were matched 1:1 using high-dimensional propensity scores (hdPS). The primary outcome was time-to-escalation to triple therapy. Results For the prespecified study period in the hdPS-matched cohort, escalation to triple therapy was infrequent among new users of tiotropium/olodaterol (n = 1302, 7 escalation events) and tiotropium monotherapy (n = 1302, 8 escalation events). The difference in time-to-escalation to triple therapy between groups was not statistically significant (median [interquartile range]: 28 days [15.0–139.2] for tiotropium monotherapy vs 193 days [94.5–302.0] for tiotropium/olodaterol; hazard ratio: 0.89; 95% CI: 0.32–2.46). Similar findings (hazard ratio: 0.71; 95% Cl: 0.36–1.40) were observed in a post hoc analysis, which extended the study period by 1 year to 31 March 2020. Risks of first moderate and/or severe COPD exacerbation were lower for tiotropium/olodaterol than tiotropium monotherapy (between-group differences not significant). There were no significant between-group differences for the risks of all-cause inpatient mortality, major adverse cardiovascular events, and first use of home oxygen therapy. Conclusions ICS monotherapy or ICS/LABA added to tiotropium or tiotropium/olodaterol is limited in Japanese clinical settings. The number of escalations to triple therapy was very limited in the dataset and there was insufficient power to detect differences between the treatment groups in the primary hdPS-matched cohort.

Abstract
The effectiveness and safety of fixed dual long-acting bronchodilators for chronic obstructive pulmonary disease (COPD) patients have been well established; however, there is a paucity of clinical effectiveness comparison in patients with COPD treatment. The aim of the current study was to compare the effectiveness of three once-daily dual bronchodilator agents in patients with COPD. Patients with diagnosed COPD and treated with a long-acting beta-agonist (LABA) + long-acting muscarinic antagonist (LAMA) fixed-dose combination therapy (UME/VIL (umeclidinium and vilanterol inhalation powder), IND/GLY (indacaterol and glycopyrronium), and TIO/OLO (tiotropium and olodaterol)) were enrolled in this retrospective study over a period of 12 months. Effectiveness assessments were evaluated using a COPD assessment test (CAT) and lung function parameters. Besides, times for acute exacerbation were also assessed. The enrolled patients’ number was 177 in IND/GLY, 176 in UME/VIL and 183 in TIO/OLO. Lung function measurements with FEV1 had significantly improved for patients using TIO/OLO (98.7 mL) compared to those of IND/GLY (65.2 mL) and UME/VIL (64.4 mL) (p < 0.001). CAT scores were also significantly decreased in patients treated with TIO/OLO (CAT down 5.6) than those with IND/GLY (3.8) and UME/VIL (3.9) (p = 0.03). Acute exacerbation was also reduced in patients using TIO/OLO (4.9%) compared with those using IND/GLY (10.2%) and UME/VIL (11.9%) (p = 0.01). Significant improvement in pulmonary function, symptoms were demonstrated after 12 months of LABA/LAMA fixed-dose combination therapy with three different treatment options. TIO/OLO demonstrated higher therapeutic effects compared with UME/VIL or IND/GLY. Determining clinical relevance will require a well-designed randomized controlled trial.

Abstract
BACKGROUND In symptomatic COPD patients with a history of exacerbations, additional treatment with inhaled corticosteroid (ICS) to long-acting muscarinic antagonist (LAMA) and long-acting beta-agonist (LABA) combination therapy is recommended based on the evidence of low incidence of exacerbations but with a caution for pneumonia. However, ethnic differences may affect the response to drugs. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of this treatment in the Japanese population (PROSPERO: CRD42020191978). METHODS We searched relevant randomized control trials and analyzed the exacerbations, quality of life, lung function, and adverse events including pneumonia and mortality as the outcomes of interest. RESULTS We identified a total of three RCTs (N = 632). Treatment with ICS/LAMA/LABA triple therapy significantly decreased the exacerbations (rate ratio, 0.56; 95% CI, 0.38 to 0.85) and improved the trough FEV1 (mean difference, 0.04; 95% CI, 0.01 to 0.07) compared to LAMA/LABA therapy. However, triple therapy showed a significantly higher incidence of pneumonia compared to LAMA/LABA (odds ratio, 3.38; 95% CI, 1.58 to 7.22). Concerning other adverse events including mortality, there were no significant difference between these therapies. CONCLUSIONS In the current meta-analysis of the Japanese population, we confirmed that triple therapy causes a higher incidence of pneumonia than LAMA/LABA treatment but is a more preferable treatment since it showed a lower incidence of exacerbations and higher trough FEV1 in patients with symptomatic moderate to severe COPD. However, since the sample sizes were not statistically large enough, further trials involving Japanese patients are needed.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease with a complex progression of many clinical presentations, and clinically important deterioration (CID) has been proposed in the Western studies as a composite endpoint of disease progression. The aim of this study was to investigate the relationships between 1-year CID and the following long-term clinical outcomes in Japanese patients with COPD who have been reported to have different characteristics compared to the Westerners. METHODS Among Japanese patients with COPD enrolled in the Hokkaido COPD cohort study, 259 patients who did not drop out within the first year were analyzed in this study. Two definitions of CID were used. Definition 1 comprised ≥ 100 mL decrease in forced expiratory volume in 1 s (FEV1), ≥ 4-unit increase in St George's Respiratory Questionnaire (SGRQ) score from baseline, or moderate or severe exacerbation. For Definition 2, the thresholds for the FEV1 and SGRQ score components were doubled. The presence of CID was evaluated within the first year from enrollment, and analyzed the association of the presence of CID with following 4-year risk of exacerbations and 9-year mortality. RESULTS Patients with CID using Definition 1, but not any single CID component, during the first year had a significantly worse mortality compared with those without CID. Patients with CID using Definition 2 showed a similar trend on mortality, and had a shorter exacerbation-free survival compared with those without CID. CONCLUSIONS Adoption of CID is a beneficial and useful way for the assessment of long-term disease progression and clinical outcomes even in Japanese population with COPD. The definition of CID might be optimized according to the characteristics of COPD population and the observation period for CID.

Introduction In the IMPACT trial, single-inhaler triple therapy fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) reduced moderate/severe exacerbation rates versus FF/VI or UMEC/VI dual therapy in patients with chronic obstructive pulmonary disease (COPD); however, pneumonia incidence was higher in FF-containing arms. As COPD is a growing problem in Asia, we compared the efficacy and safety of FF/UMEC/VI in Asia versus non-Asia regions. Methods IMPACT was a double-blind, 52-week trial in symptomatic COPD patients with ≥ 1 moderate/severe exacerbation in the prior year. This pre-specified analysis evaluated the annual rate of moderate/severe exacerbations, change from baseline in trough forced expiratory volume in 1 s, and St George’s Respiratory Questionnaire total score, mortality, and safety (including pneumonia) in Asia versus non-Asia regions. Results The intent-to-treat population comprised 10,355 patients (Asia n = 1644 [16%]). Rate ratios (95% confidence intervals) for moderate/severe exacerbations with FF/UMEC/VI were 0.89 (0.76–1.05) versus FF/VI and 0.86 (0.71–1.04) versus UMEC/VI in Asia, and 0.84 (0.79–0.90) and 0.74 (0.68–0.80) in non-Asia. Efficacy of FF/UMEC/VI on other endpoints was similar in both regions. There was an increased incidence of investigator-reported pneumonia in patients in Asia (FF/UMEC/VI: 13%; FF/VI: 14%; UMEC/VI: 6%) compared with non-Asia (FF/UMEC/VI: 6%; FF/VI: 5%; UMEC/VI: 4%). The increased risk of pneumonia in patients in Asia was most marked in patients with lower body mass index, lower lung function, and taking inhaled corticosteroids. In post hoc analysis of adjudicated on-treatment all-cause mortality, probabilities of death were numerically lower in both regions with FF/UMEC/VI (Asia: 1.16%; non-Asia: 1.35%) and FF/VI (Asia: 1.77%; non-Asia: 1.21%) versus UMEC/VI (Asia: 1.91%; non-Asia: 2.23%). Conclusions FF/UMEC/VI provides similar benefits in COPD patients in Asia and non-Asia regions. Clinical benefits of treatment, including reduction in mortality risk, should be weighed against risk of pneumonia, taking account of all known risk factors.

Efficacy and safety of glycopyrrolate/formoterol fumarate metered dose inhaler delivered using co-suspension delivery technology in Japanese patients with moderate-to-very severe chronic obstructive pulmonary disease. Respir Investig 2020; 59:135-144. [PMID: 32917556 DOI: 10.1016/j.resinv.2020.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 06/12/2020] [Accepted: 06/28/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND PINNACLE-4 evaluated the efficacy and safety of the long-acting muscarinic antagonist/long-acting β2-agonist fixed-dose combination glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI) in patients from Asia, Europe, and the USA with moderate-to-very severe chronic obstructive pulmonary disease (COPD). This pre-specified analysis included Japanese patients in PINNACLE-4. METHODS In this double-blind randomized study (NCT02343458), patients received GFF MDI (18/9.6 μg), glycopyrrolate (GP) MDI (18 μg), formoterol fumarate (FF) MDI (9.6 μg), or placebo MDI twice daily for 24 weeks. The primary endpoint was change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over Weeks 12-24. Secondary lung function endpoints, patient-reported outcomes, and safety were assessed. The Japanese subpopulation (n = 150) analyses were exploratory. RESULTS GFF MDI improved change from baseline in morning pre-dose trough FEV1 over Weeks 12-24 versus GP MDI, FF MDI, and placebo MDI (least squares mean [LSM] differences [95% confidence interval]: 69 [8-131], 60 [-1 to 121], and 275 [180-370] mL, respectively). GFF MDI numerically improved Transition Dyspnea Index focal score and change from baseline in St George's Respiratory Questionnaire total score versus placebo MDI (LSM differences 0.19 and -3.78, respectively). Treatment-related adverse events occurred in ≤4.5% of patients in any treatment group. CONCLUSIONS GFF MDI improved lung function versus monocomponents and placebo MDI in the Japan subpopulation of PINNACLE-4. The efficacy and safety results were generally consistent with those of the global study population, supporting the use of GFF MDI in Japanese patients with moderate-to-very severe COPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is one of the major causes of morbidity and mortality worldwide and in China. For patients with more severe symptoms, initial treatment with long acting β2-agonists and long-acting muscarinic antagonists combination therapy is recommended. Tiotropium + olodaterol fixed-dose combination (Tio + Olo FDC) is an aqueous solution of tiotropium bromide and olodaterol delivered by the RESPIMAT® Soft Mist™ inhaler for patients with moderate to very severe COPD. METHODS This single site, open-label, phase Ib clinical study assessed the pharmacokinetic (PK) and safety profiles of once-daily Tio + Olo FDC (5 μg/5 μg) after single dose and at steady state in Chinese patients with moderate to severe COPD over 3 weeks. The PK and safety profiles of Japanese and Caucasian populations from 2 independent COPD studies were provided for comparison. RESULTS A total of 12 Chinese patients received Tio + Olo FDC. After multiple inhaled administration of Tio + Olo FDC, tiotropium and olodaterol were rapidly absorbed and reached peak plasma concentration at about 5 and 25 min, respectively. The accumulation ratios after multiple administrations were 1.3 and 1.6 for tiotropium and olodaterol in Chinese patients. Tio + Olo FDC was well-tolerated; all AEs were mild. CONCLUSION Tio + Olo FDC (5 μg/5 μg) was rapidly absorbed and had a good safety profile in Chinese patients with COPD.

Abstract
Purpose Causes of death may be unique and different in Japanese patients with COPD because they are generally older, thinner, experience fewer exacerbations, and live longer than those in other countries. We investigated the detailed mortality profile in the Hokkaido COPD cohort study, which completed a 10-year follow-up with a very low dropout rate. Patients and Methods We prospectively examined the 10-year natural history in 279 Japanese patients with COPD (GOLD 1, 26%; GOLD 2, 45%; GOLD 3, 24%; and GOLD 4, 5%). The majority of patients were male, and the average age at baseline was 69 years old. About 95% of all patients had accurate mortality data. The risk factors for mortality were also analyzed. Results During the 10 years, 112 patients (40%) died. Their median survival time was 6.1 years (interquartile range: 4.7–7.9 years), and age at death was 79 ± 6 years old (mean ± SD). Respiratory diseases, including pneumonia, were the leading causes of death in 45 (40%), followed by lung cancer in 24 (21%), other cancers in 18 (16%), and cardiovascular diseases in 12 (11%). In particular, lung cancer-related death was equally distributed across all COPD stages, with a higher proportion of lung cancer in the relatively younger generation (<64 years old). Older age at baseline, lower BMI, and severer emphysema were significant risk factors for all-cause mortality. Conclusion The unique mortality profile observed in this study should be considered when designing strategies for the management of patients with COPD in any geographic region.

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 KRONOS, a Phase III, multicenter, randomized, double-blind study (NCT02497001) conducted in Canada, China, Japan, and the USA, assessed the efficacy and safety of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI), a triple fixed-dose combination therapy, relative to dual therapies in patients with moderate-to-very severe COPD. Here we present findings from the Japanese subgroup of KRONOS. Methods Patients received BGF MDI 320/18/9.6μg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6μg, budesonide/formoterol fumarate (BFF) MDI 320/9.6μg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12μg twice-daily for 24 weeks. The primary endpoint was the change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over Weeks 12-24. Symptoms, quality of life, exacerbations, and safety were also assessed. Results In total, 416 Japanese patients (21.9% of the global KRONOS population) were randomized and treated with BGF MDI (n=139), GFF MDI (n=138), BFF MDI (n=70), or BUD/FORM DPI (n=69). Nominally significant improvements in the change from baseline in morning pre-dose trough FEV1 over Weeks 12-24 were observed for BGF MDI vs GFF MDI (least squares mean [LSM] difference 37 mL, 95% confidence interval [CI] 3, 72; P=0.0337) and BFF MDI (67 mL; 95% CI 25, 109; P=0.0020). Treatment with BGF MDI led to a nominally significant reduction in the rate of moderate/severe exacerbations vs GFF MDI (rate ratio 0.40, 95% CI 0.19, 0.83; P=0.0142). Compared with dual therapies, numerical improvements were observed with BGF MDI for Transition Dyspnea Index focal score and the change from baseline in Evaluating Respiratory Symptoms in COPD total score (P≤0.3899). All treatments were generally well tolerated. Conclusion BGF MDI nominally significantly improved lung function and numerically improved symptoms vs GFF MDI and BFF MDI. BGF MDI nominally significantly reduced exacerbations vs GFF MDI in Japanese patients with COPD. Efficacy and safety findings were generally comparable to those in the global KRONOS population.

Abstract
Tiotropium/olodaterol (Stiolto® Respimat®; Spiolto® Respimat®) is an inhaled fixed-dose combination of the long-acting muscarinic antagonist tiotropium bromide (hereafter referred to as tiotropium) and the long-acting β2-adrenergic agonist olodaterol. It is available in several countries, including the USA, Japan, China and those of the EU, where it is indicated for the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). The efficacy of tiotropium/olodaterol 5/5 μg/day in patients with COPD was evaluated in phase III or IV trials of 6-52 weeks' duration. Tiotropium/olodaterol improved lung function to a greater extent than each of its individual components or placebo in 12- and 52-week trials. In 6-week trials, tiotropium/olodaterol provided greater lung function benefits over 24 h than the individual components, placebo or twice-daily fluticasone propionate/salmeterol. Tiotropium/olodaterol also demonstrated beneficial effects on health-related quality of life (HR-QoL), dyspnoea, inspiratory capacity, exercise endurance and the need for rescue medication. In an 8-week open-label trial, umeclidinium/vilanterol was superior to tiotropium/olodaterol for the primary endpoint of trough forced expiratory volume in 1 s. The tolerability profile of tiotropium/olodaterol was generally similar to that of the individual components. In conclusion, tiotropium/olodaterol provides a useful option for the maintenance treatment of COPD, with the convenience of once-daily administration via a single inhaler.

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
Maintenance bronchodilator therapy with long-acting β-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) is the cornerstone treatment for patients with stable chronic obstructive pulmonary disease (COPD). Fixed-dose combinations (FDCs) of LABA/LAMA are recommended for the majority of symptomatic COPD patients by global guidelines; regional guidelines such as the Japanese and Korean guidelines also provide similar recommendations for the use of LABA/LAMA FDCs. This review comprehensively describes the latest clinical evidence from key studies on the efficacy and safety of four approved LABA/LAMA fixed-dose combinations: indacaterol/glycopyrronium, vilanterol/umeclidinium, formoterol/aclidinium, and olodaterol/tiotropium. Additionally, in this review we describe the rationale behind the use of LABA/LAMA FDC therapy, key findings from the preclinical and clinical trial evaluation of respective LABA and LAMA monocomponents, and the efficacy and safety of LABA/LAMA FDCs. Special emphasis is placed on the clinical evidence for the monocomponents and LABA/LAMA FDCs from the Asian population. This detailed overview of the efficacy and safety of LABA/LAMA FDCs in global and Asian COPD patients is envisaged to provide a better understanding of the benefits of these therapies and to inform healthcare providers and patients on their appropriate use.Funding: Novartis Pharma K.K.

Ther Adv Respir Dis 2019; 13:1753466619843426.

Abstract
Long-acting bronchodilators are the cornerstone of pharmacologic treatment of chronic obstructive pulmonary disease (COPD). Spiolto® or Stiolto® is a fixed-dose combination (FDC) containing two long-acting bronchodilators, the long-acting muscarinic receptor antagonist tiotropium (TIO) and the long-acting β2-adrenoceptor agonist olodaterol (OLO), formulated in the Respimat® Soft Mist™ inhaler. A total of 13 large, multicentre studies of up to 52 weeks' duration have documented its efficacy in more than 15,000 patients with COPD. TIO/OLO 5/5 µg FDC significantly increases pulmonary function compared with placebo and its respective constituent mono-components TIO 5 µg and OLO 5 µg. TIO/OLO 5/5 µg also results in statistically and clinically significant improvements in patient-reported outcomes, such as dyspnoea, use of rescue medication, and health status. Addition of OLO 5 µg to TIO 5 µg reduces the rate of moderate-to-severe exacerbations by approximately 10%. Compared with placebo and TIO 5 µg, TIO/OLO 5/5 µg significantly improves exercise capacity (e.g. endurance time) and physical activity, the latter increase being reached by a unique combination behavioural modification intervention, dual bronchodilatation and exercise training. Overall, the likelihood for patients to experience a clinically significant benefit is higher with TIO/OLO 5/5 µg than with its constituent mono-components, which usually yield smaller improvements which do not always reach statistical significance, compared with baseline or placebo. This supports the early introduction of TIO/OLO 5/5 µg in the management of patients with symptomatic COPD.

Abstract
Background The use of inhaled corticosteroid (ICS) in patients with chronic obstructive pulmonary disease (COPD) decreases the frequency of COPD exacerbations. Recently, pneumonia was reported as a complication of ICS in patients with COPD. However, there have been few reports concerning the relationship between ICS and pneumonia in Japan. Moreover, there is little information on the types of ICS. Patients and methods To clarify these issues, we investigated the occurrence of pneumonia in Japanese patients with COPD. We retrospectively investigated the occurrence of pneumonia in patients with COPD in our hospital from January 2009 to August 2013. Morbidity and mortality, ICS use, age, sex, and COPD classification were investigated. A group of patients with COPD who received ICS and a group of patients with COPD who did not receive ICS were compared each other. Results Fifty-one patients developed pneumonia among 639 (7.98%) patients with COPD. Among 252 ICS-treated patients with COPD, 13 (5.16%) developed pneumonia, and among 387 ICS-untreated patients with COPD, 38 (9.82%) developed pneumonia. The mortality rate in ICS-treated patients with COPD was 7.7%, while that in ICS-untreated patients was 10.5% (P=0.767). Fluticasone/salmeterol use tended to show a higher risk of pneumonia than budesonide/formoterol use. The use of ICS did not increase the risk of pneumonia or mortality due to pneumonia in Japanese patients with COPD. Conclusion ICS might not increase the risk of pneumonia in Japanese patients with COPD. In regard to pneumonia, ICS can be safely used in Japanese patients with COPD. Because there are apparent differences in lung diseases among races, appropriate treatment should be investigated in each country.

Abstract
Background COPD remains a major health problem in Japan. Patients with COPD experience a reduced quality of life (QoL) and have a higher chance of work impairment and productivity loss. However, there is a lack of data on the impact of COPD in terms of QoL and work activity impairment in Japan. This study assessed the socioeconomic burden of COPD in Japan and the impact it may have on the working age population. Patients and methods This was a 2-year retrospective chart review in COPD patients aged ≥40 years, with at least one health care visit to clinic or hospital in the previous 12 months. Patients were required to have available medical charts for at least the previous 24 months. Symptoms were assessed using COPD assessment test score; EuroQoL Group 5 Dimension (EQ-5D-5L) and work productivity and activity impairment general health questionnaires were used to evaluate health-related QoL and work productivity, and health care resource utilization data were obtained from clinical charts. Results In total, 71 patients aged <65 years, and 151 patients aged ≥65 years were included; the majority of patients had moderate or severe airflow limitation. Exacerbations (moderate or severe) were reported by ~35% of patients in both age groups; 52.1% and 62.9% of patients in the <65-year and ≥65-year age groups had COPD assessment test scores ≥10. EQ-5D-5L index scores in the <65-year and ≥65-year age groups were 0.79 and 0.77, respectively. Work productivity and activity impairment scores were higher in <65-year age group. Annual costs of health care resource use per patient in the <65-year and ≥65-year age groups were ¥438,975 (US$4,389) and ¥467,871 (US$4,678), respectively. Costs due to productivity loss were estimated to be ¥5,287,024 (US$52,870) in the <65-year age group and ¥3,018,974 (US$30,187) in the ≥65-year age group. Conclusion COPD represents a significant socioeconomic burden in Japan. Patients with COPD report significant use of health care resources. Higher impact on work impairment and productivity loss was observed frequently in the working age population.

Abstract
Background The DYNAGITO study was a Phase IIIb, randomized, double-blind, multicenter, active-controlled, parallel-group, 52-week study designed to determine the efficacy and safety of tiotropium and olodaterol combination therapy (TIO+OLO 5/5 μg) versus tiotropium monotherapy (TIO 5 μg) for reducing moderate-to-severe exacerbations of COPD. This is a prespecified analysis of the DYNAGITO data in Japanese patients. Patients and methods Enrolled patients had a diagnosis of COPD with at least one moderate-to-severe exacerbation in the previous 12 months. Of the total 7,880 treated patients in the DYNAGITO study, 461 (TIO+OLO 5/5 μg: n=226, TIO 5 μg: n=235) were Japanese. The primary endpoint was the annualized rate of moderate-to-severe COPD exacerbations. The key secondary endpoint was the time to first moderate-to-severe COPD exacerbation, and other secondary endpoints included the annualized rate of exacerbations leading to hospitalization, time to first COPD exacerbation leading to hospitalization, and all-cause mortality. Safety data were analyzed descriptively. Results Combination therapy with TIO+OLO resulted in a 29% lower rate of moderate-to-severe COPD exacerbations relative to TIO monotherapy (rate ratio 0.71; 99% CI: 0.46, 1.10; p=0.0434). The risk of a first moderate-to-severe COPD exacerbation was 19% lower with TIO+OLO combination therapy than with TIO monotherapy (HR 0.81; 99% CI: 0.57, 1.17; p=0.1379), although this difference was not statistically significant. The annualized rate of COPD exacerbations requiring hospitalization was 14% lower in the TIO+OLO arm than in the TIO arm (rate ratio 0.86; 95% CI: 0.52, 1.42; p=0.5654). The adverse event incidence was balanced between treatment arms. Conclusion In a prespecified subgroup analysis of Japanese patients in the DYNAGITO study, combination therapy with TIO+OLO was more effective than TIO in reducing exacerbations. Both treatments were well tolerated.

Tuberc Respir Dis (Seoul) 2018; 81:198-215. [PMID: 29926556 PMCID: PMC6030660 DOI: 10.4046/trd.2018.0040] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2018] [Revised: 04/26/2018] [Accepted: 04/29/2018] [Indexed: 12/21/2022] Open
Abstract
Bronchodilators provide improvements in lung function and reductions in symptoms and exacerbations, and are the mainstay of pharmacological management of chronic obstructive pulmonary disease (COPD). The Global Initiative for Chronic Obstructive Lung Disease strategy recommends the use of a combination of long-acting β₂-agonist/long-acting muscarinic antagonists (LABA/LAMA) as the first-line treatment option in the majority of symptomatic patients with COPD. This review provides an indirect comparison of available LABA/LAMA fixed-dose combinations (FDCs) through discussion of important efficacy and safety data from the key literature, with the objective of providing physicians with a framework for informed decision-making. LABA/LAMA FDCs provided greater benefits compared with placebo and similar or greater benefits compared with tiotropium and salmeterol/fluticasone in improving lung function, dyspnea, health-related quality of life, reducing rescue medication use and preventing exacerbations, although with some variability in efficacy between individual FDCs; further, tolerability profiles were comparable among LABA/LAMA FDCs. However, there is a disparity in the amount of evidence generated for different LABA/LAMA FDCs. Thus, this review shows that all LABA/LAMA FDCs may not be the same and that care should be taken when extrapolating individual treatment outcomes to the entire drug class. It is important that physicians consider the efficacy gradient that exists among LABA/LAMA FDCs, and factors such as inhaler devices and potential biomarkers, when choosing the optimal bronchodilator treatment for long-term management of patients with COPD.

Abstract
BACKGROUND Diabetes has been reported as a comorbidity of chronic obstructive pulmonary disease (COPD) in Western countries, but it has not been demonstrated in epidemiological reports in Japan. The purpose of this study was to clarify whether the relationship between airflow obstruction and diabetes can be confirmed in a Japanese general population. METHODS From 2004 to 2006, blood sampling and pulmonary function tests were performed on 3045 people over the age of 40 years in annual health check-ups held in Takahata, Yamagata Prefecture, Japan. Pulmonary function was re-evaluated in 2009 and 2011. RESULTS The prevalence of diabetes did not differ between subjects with and without airflow obstruction. Furthermore, although body mass index decreased, no increase in the prevalence of diabetes was observed with the progression of airflow obstruction. The annual changes in forced expiration volume in 1s (FEV1) did not differ depending on the presence or absence of diabetes in the study population. CONCLUSION There was no difference in the prevalence of diabetes between subjects with airflow obstruction and those without. As patients with COPD in Japan are thinner than in the West, diabetes may not be a common comorbidity in Japanese patients with COPD.

Abstract
Introduction The superiority of tiotropium/olodaterol is demonstrated in improvement of lung function, dyspnea, lung hyperinflation, and quality of life compared with either monotherapy in patients with chronic obstructive pulmonary disease (COPD). Japanese Respiratory Society Guidelines for COPD management include improvement of exercise tolerance and daily physical activity as the treatment goals; however, there is limited evidence in Japanese patients with COPD. Methods A protocol is developed for the VESUTO® study that investigates the efficacy of tiotropium/olodaterol fixed-dose combination (FDC) compared with tiotropium alone on inspiratory capacity (IC, volume from functional residual capacity to total lung capacity), exercise capacity, and daily physical activity in Japanese patients with COPD. Results A total of 180 Japanese patients with COPD, aged ≥40 years will be enrolled into the double-blind, multicenter, active-controlled, crossover study (NCT02629965) and will be randomized to receive either tiotropium/olodaterol FDC or tiotropium for 6 weeks each [two puffs via RESPIMAT® (Boehringer Ingelheim, Ingelheim, Germany) inhaler in the morning]. The primary endpoint is IC at rest measured at 60 min post-dose after 6 weeks treatment. The secondary endpoints include the 6-min walk distance (6MWD) at 90 min post-dose and physical activity measured by the activity monitor in the last 2 weeks of the 6-week treatment periods. Lung function tests will also be assessed after 6 weeks treatment. A mixed-effects model repeated measures approach will be used for the primary and secondary endpoints. Conclusion The VESUTO® study is the first randomized interventional study to investigate exercise capacity (6MWD) and physical activity measured by a 3-axis accelerometer in Japanese patients with COPD. The study could provide additional evidence of long-acting muscarinic antagonist (LAMA) + long-acting β2-agonist (LABA) combination therapy on patients’ physical activities as well as lung function. Trial registration ClinicalTrials.gov: NCT02629965 (registered on December 1, 2015). Funding The VESUTO study was funded by Nippon Boehringer Ingelheim Co., Ltd., Tokyo, Japan.

Abstract
BACKGROUND The efficacy and safety of once-daily tiotropium+olodaterol (T+O) (2.5/5µg or 5/5µg) for treating chronic obstructive pulmonary disease (COPD) have been demonstrated in the large, multinational, randomized, Phase III studies TONADO® 1 and 2, which included 413 Japanese patients (~80 in each group). This study was conducted to supplement the TONADO® study data to assess long-term safety in ≥100 Japanese patients treated for 1 year in compliance with International Conference on Harmonisation guidelines. Efficacy was evaluated descriptively as a secondary end point. METHODS Patients were randomized to 52 weeks of double-blind treatment with once-daily T+O (2.5/5 or 5/5µg) or O (5µg) monotherapy via the Respimat® inhaler. We report the safety and efficacy data descriptively. RESULTS The incidence of adverse events (AEs) was comparable in the T+O 2.5/5µg (75.0%), T+O 5/5µg (85.4%), and O 5µg (80.5%) groups, with drug-related AEs being reported in 5.0%, 7.3%, and 4.9% of patients, respectively. Serious AEs were reported in 14 patients (11.5%). The change from baseline in forced expiratory volume in 1s (FEV1) area under the curve from 0 to 3h and trough FEV1 were numerically higher in the T+O treatment groups than in the O monotherapy group throughout the study period. Overall safety of T+O was comparable to that in the TONADO® studies. CONCLUSIONS No safety concerns for long-term T+O treatment were identified in Japanese patients with COPD. A numerical improvement in lung function was observed with T+O treatment compared to O monotherapy.
