Abstract
BACKGROUND Indacaterol is an inhaled long-acting beta2-agonist that is administered once daily and has been investigated as a treatment for chronic obstructive pulmonary disease (COPD). Four different doses have been investigated (75 mcg, 150 mcg, 300 mcg and 600 mcg). The relative effects of different doses of once-daily indacaterol in the management of patients with COPD are uncertain. OBJECTIVES To compare the efficacy and safety of indacaterol versus placebo and alternative twice-daily long-acting beta2-agonists for the treatment of patients with stable COPD. SEARCH METHODS We identified trials from the Cochrane Airways Group Specialised Register of trials (CAGR), handsearched respiratory journals and meeting abstracts and searched the Novartis trials registry and ClinicalTrials.gov. The date of the most recent search was 8 November 2014. SELECTION CRITERIA We included all randomised controlled trials comparing indacaterol at any dose versus placebo or alternative long-acting beta2-agonists. Trials were required to be of at least 12 weeks' duration and had to include adults older than 18 years with a confirmed spirometric diagnosis of COPD. DATA COLLECTION AND ANALYSIS Two review authors (JBG, EJD) independently assessed for possible inclusion all citations identified as a result of the search. Disagreements were resolved through discussion or, if required, through resolution by a third review author (RWB). One review author (JBG) extracted data from trials identified by the search and entered these data into Review Manager 5.1 for statistical analysis. Data entry was cross-checked by a second review author (EJD, CJC). MAIN RESULTS A total of 13 trials with 9961 participants were included in the review. Ten trials with a total of 8562 participants involved an indacaterol versus placebo comparison. Five trials with a total of 4133 participants involved an indacaterol versus twice-daily beta2-agonist comparison. The comparator beta2-agonists were salmeterol, formoterol and eformoterol. One of these trials, with a total of 90 participants, provided no data that could be used in this review. Two trials included both indacaterol versus placebo and indacaterol versus twice-daily beta2-agonist comparisons. Trials were between 12 weeks and 52 weeks in duration. Overall the quality of the evidence was strong, and risk of significant bias was minimal in most of the included studies. Enrolled participants had stable COPD across a range of spirometric severities. Forced expiratory volume in 1 second (FEV1) was generally between 30% and 80% predicted, and a mean FEV1 of approximately 50% was predicted in most studies. Patients with concurrent respiratory disease, including asthma, were excluded. Concomitant use of inhaled corticosteroids was permitted.The primary objectives were to compare trough FEV1 at the end of dosing, exacerbation rates and quality of life. Significant adverse events, mortality and dyspnoea were included as secondary outcomes. Compared with placebo, a significant and clinically relevant improvement in trough FEV1 was noted with indacaterol (mean difference (MD) 149.11, 95% confidence interval (CI) 137.09 to 161.12). In addition, compared with placebo, a significant improvement in mean St George Respiratory Questionaire (SGRQ) score (MD -3.60, 95% CI -4.36 to -2.83) was reported, and the proportion of participants experiencing clinically relevant improvement in SGRQ score was significantly greater (odds ratio (OR) 1.63, 95% CI 1.46 to 1.84). Compared with twice-daily beta2-agonists, a small but statistically significant increase in trough FEV1 was seen with indacaterol (MD 61.71 mL, 95% CI 41.24 to 82.17). Differences between indacaterol and twice-daily beta2-agonists in mean SGRQ scores (MD -0.81, 95% CI -2.28 to 0.66) and in the proportions of participants achieving clinically relevant improvements in SGRQ scores (OR 1.07, 95% CI 0.87 to 1.32) were not statistically significant, but the confidence intervals are too wide to permit the conclusion that the treatments were equivalent. Data were insufficient for analysis of differences in exacerbation rates for both placebo and twice-daily beta2-agonist comparisons. AUTHORS' CONCLUSIONS For patients with stable COPD, use of indacaterol versus placebo results in statistically significant and clinically meaningful improvements in lung function and quality of life. The clinical benefit for lung function is at least as good as that seen with twice-daily long-acting beta2-agonists. The comparative effect on quality of life remains uncertain, as important differences cannot be excluded.

Abstract
Purpose In the absence of head-to-head clinical trials comparing the once-daily, long-acting beta2-agonists olodaterol and indacaterol for the treatment of chronic obstructive pulmonary disease (COPD), an indirect treatment comparison by systematic review and synthesis of the available clinical evidence was conducted. Methods A systematic literature review of randomized, controlled clinical trials in patients with COPD was performed to evaluate the efficacy and safety of olodaterol and indacaterol. Network meta-analysis and adjusted indirect comparison methods were employed to evaluate treatment efficacy, using outcomes based on trough forced expiratory volume in 1 second (FEV1), Transition Dyspnea Index, St George’s Respiratory Questionnaire total score and response, rescue medication use, and proportion of patients with exacerbations. Results Eighteen trials were identified for meta-analysis (eight, olodaterol; ten, indacaterol). Olodaterol trials included patients of all severities, whilst indacaterol trials excluded patients with very severe COPD. Concomitant maintenance bronchodilator use was allowed in most olodaterol trials, but not in indacaterol trials. When similarly designed trials/data were analyzed for change from baseline in trough FEV1 (liters), the following mean differences (95% confidence interval) were observed: trials excluding concomitant bronchodilator: indacaterol 75 mcg versus olodaterol 5 mcg, −0.005 (−0.077 to 0.067), and indacaterol 150 mcg versus olodaterol 5 mcg, 0.020 (−0.036 to 0.077); trials with concomitant tiotropium: indacaterol 150 mcg versus olodaterol 5 mcg, 0.000 (−0.043 to 0.042). In sensitivity analyses of the full network, results for change from baseline in trough FEV1 favored indacaterol, but this dataset suffered from trial design heterogeneity. For the other endpoints investigated, no statistically significant differences were found when analyzed in the full network. Conclusion When compared under similar trial conditions, olodaterol and indacaterol have similar efficacy in patients with COPD. This research highlights the importance of considering the concomitant COPD medication when evaluating treatment effects in COPD.

Abstract
Background Indacaterol is a novel, once-daily, inhaled, long-acting b2-agonist for patients with chronic obstructive pulmonary disease (COPD). The study objective was to evaluate the efficacy of indacaterol on quality of life and pulmonary function in patients with COPD in a real-world setting, and also to evaluate its inhaler device (Breezhaler®), which is important for both adherence and management. Methods Twenty-eight outpatients with COPD were treated with indacaterol (150 μg once daily for 8 weeks), and the effects on pulmonary function were evaluated using a questionnaire survey with the modified Medical Research Council (mMRC) dyspnea scale and COPD assessment test (CAT) before and after treatment. Similar investigations were also performed separately among different baseline medications. Moreover, original questionnaire surveys for indacaterol and its device were performed. Results Overall, mMRC dyspnea scale and CAT scores significantly improved (1.96±1.04 to 1.57±1.07 and 17.39±8.23 to 12.82±8.42, respectively; P<0.05). Significant improvements in forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were also observed on pulmonary function tests (2.91±0.66 L to 3.07±0.65 L and 1.46±0.60 L to 1.58±0.59 L, respectively; P<0.05). Replacement therapy from salmeterol to indacaterol significantly improved mMRC and FVC values, but did not significantly improve CAT scores or other pulmonary functions. Add-on therapy with indacaterol significantly improved mMRC score, CAT score, FVC, and FEV1, regardless of whether tiotropium was used as a baseline treatment. All subjects in a questionnaire survey found the inhaler device easy to use. There were no serious adverse events leading to treatment discontinuation. Conclusion Indacaterol is thought to be effective and well tolerated as a bronchodilator for the management of COPD. Treatment with indacaterol in addition to a long-acting muscarinic antagonist was also useful.

Abstract
Background Once-daily long-acting β2-agonists (LABAs) are an important treatment option, either alone or in combination with other inhaled long-acting bronchodilators in the management of chronic obstructive pulmonary disease (COPD). Aims/objectives To audit the effectiveness of indacaterol as maintenance therapy in patients with moderate-to-severe COPD (Global initiative for chronic Obstructive Lung Disease [GOLD] stage II/III). Methods This was a single-center audit of a primary care COPD cohort comprising all patients treated with indacaterol following treatment escalation (as per National Institute for Health and Care Excellence guidelines) or failure with other therapies. The sample was restricted to patients treated for a minimum of 12 months with indacaterol, for whom preswitching and follow-up spirometry as well as exacerbation frequency data were available (GOLD spirometry guidelines). Pulmonary function was assessed by spirometry (recorded as forced expiratory volume in 1 second [FEV1] expressed as percentage predicted). Relevant self-reported qualitative information was recorded in descriptive terms for quality of life (QoL) assessment. Results A total of 15 patients met the audit inclusion criteria (66.6% male, mean age 64.9±7.7 years). COPD disease duration ranged from 1 to 22 years; 93% had GOLD stage II or III COPD. Follow-up ranged in duration from 12 to 27 months. Indacaterol was associated with a significant reduction in exacerbation frequency compared with the 12 months prior to initiation (P=0.02). In those patients who experienced three or more exacerbations/year, mean exacerbation rate fell from 5.43±1.07 to 2.43±0.2 after 12 months treatment with indacaterol (P=0.02). A reduction in dyspnea was noted in 53% of patients. Similarly, improvements in exercise tolerance and well-being were self-reported in 67% and 93%, respectively. Conclusion Indacaterol was found to be an effective LABA as an escalation or switch medication in patients with moderate-to-severe COPD. Indacaterol was effective both as monotherapy and in combination with a long-acting muscarinic antagonist. Switching to indacaterol from a LABA/inhaled corticosteroid fixed-combination inhaler significantly reduced the number of acute exacerbations and also improved self-reported QoL.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow obstruction that can lead to lung destruction and dyspnea. Although there has been a slight reduction in mortality in recent decades, COPD is still a serious health problem that has enormous costs and utilizes significant medical resources. There have been a number of pharmacologic interventions that have been developed for the treatment of COPD. Current guidelines recommend the use of long-acting bronchodilators for the treatment of moderate and severe stage COPD, since they have been shown to improve lung function, respiratory symptoms, and quality of life. Indacaterol is a once-daily beta2-agonist (β2-agonist) delivered by a single-dose dry powder inhaler used for the treatment of COPD. It is currently approved at a dose of 75 μg in the United States and a dose of 150 μg with a maximal dose of 300 μg in Europe and other countries. Several studies show that indacaterol was statistically superior to both long-acting β2-agonist, formoterol and salmeterol, as well as, noninferior to tiotropium. Indacaterol is generally well tolerated and has a good safety profile. Other studies show that there is an additive bronchodilator response with the addition of indacaterol to tiotropium, which would provide a once-daily treatment option for patient with moderate to severe COPD. This review discusses the pharmacokinetic, comparative efficacy and safety data for indacaterol.

Abstract
Chronic obstructive pulmonary disease (COPD) has traditionally been considered an inexorably progressive disease, associated with a constant increase of symptoms that occur as the forced expiratory volume in 1 second (FEV1) worsens, only intermittently interrupted by exacerbations. However, this paradigm has been challenged in recent decades by the available evidence. Recent studies have pointed out that COPD-related symptoms are not consistently perceived by patients in the same way, showing not only seasonal variation, but also changes in symptom perception during a week or even within a single day. According to the available data, patients experience the biggest increase in respiratory symptoms during the first hours of the early morning, followed by the nighttime. This variation over time is of considerable importance, since it impacts on daily life activities and health-related quality of life, as measured by a recently developed ad hoc questionnaire. Additionally, recent clinical trials have suggested that the use of rapid-onset long-acting bronchodilators may have an impact on morning symptoms, despite their current use as maintenance treatment for a determined period. Although this hypothesis is to be validated in future long-term clinical trials comparing fast-onset versus slow-onset inhaled drugs in COPD, it may bring forward a new concept of long-term bronchodilator therapy. At the present time, the two available long-acting, fast-onset bronchodilators used in the treatment of COPD are formoterol and the recently marketed indacaterol. Newer drugs have also been shown to have a rapid onset of action in preclinical studies. Health care professionals caring for COPD patients should consider this variation in the perception of symptoms during their clinical interview as a potential new target in the long-term treatment plan.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common disease in the general population and it places a considerable burden on patients, with the disease negatively affecting quality of life. In practice, patients with COPD generally seek medical attention because of symptoms, particularly breathlessness, and the resulting physical limitations, which affect the health-related quality of life (HR-QOL) in patients. The defining feature of COPD is airflow limitation that causes air trapping and increased hyperinflation as the ventilation rate increases during physical effort. Hyperinflation causes or worsens breathlessness as breathing becomes inefficient, with the end result being an avoidance of physical exertion and a cycle of increasing dyspnea caused by inactivity and deconditioning, with deleterious effects on HR-QOL. Current published guidelines for COPD state that the goals of pharmacologic therapy should be to control symptoms, improve health status and exercise tolerance, and reduce the frequency of COPD exacerbations. Effective and sustained bronchodilation has emerged as a key strategy for improving dyspnea and ability to exercise. As there is no cure for COPD, a major goal of treatment and of research into new therapies is to improve HR-QOL in COPD patients.

Abstract
Background The current mainstay of therapy for chronic obstructive pulmonary disease (COPD) is long-acting bronchodilators. To date, the effect of indacaterol, a β2-agonist, on activities of daily living in COPD patients is not well understood. The aim of this study was to evaluate the efficacy of indacaterol with regard to activities of daily living in patients with COPD. Methods In this nonrandomized open-label study, 23 patients with COPD were instructed to carry an accelerometer for 4 weeks without indacaterol therapy and then for another period of 4 weeks while receiving indacaterol therapy. Results The number of steps, duration of moderate or greater physical activity, and energy expenditure were significantly increased after treatment with indacaterol compared with baseline data in all patients with COPD; the metabolic equivalent of task was also significantly enhanced after treatment with indacaterol. Conclusion This study provides early evidence that indacaterol improves daily physical activity in patients with COPD.
