Abstract
Isolated airway smooth muscle has been extensively investigated since 1840 to understand the pharmacology of airway diseases. There has often been poor predictability from murine experiments to drugs evaluated in patients with asthma or chronic obstructive pulmonary disease (COPD). However, the use of isolated human airways represents a sensible strategy to optimise the development of innovative molecules for the treatment of respiratory diseases. This review aims to provide updated evidence on the current uses of isolated human airways in validated in vitro methods to investigate drugs in development for the treatment of chronic obstructive respiratory disorders. This review also provides historical notes on the pioneering pharmacological research on isolated human airway tissues, the key differences between human and animal airways, as well as the pivotal differences between human medium bronchi and small airways. Experiments carried out with isolated human bronchial tissues in vitro and ex vivo replicate many of the main anatomical, pathophysiological, mechanical and immunological characteristics of patients with asthma or COPD. In vitro models of asthma and COPD using isolated human airways can provide information that is directly translatable into humans with obstructive lung diseases. Regardless of the technique used to investigate drugs for the treatment of chronic obstructive respiratory disorders (i.e., isolated organ bath systems, videomicroscopy and wire myography), the most limiting factors to produce high-quality and repeatable data remain closely tied to the manual skills of the researcher conducting experiments and the availability of suitable tissue.

Abstract
Vilanterol is a once-daily dose inhaler prescribed for asthma and chronic obstructive pulmonary disease. This study involved an investigation of vilanterol stability under acidic, basic, oxidative, thermal, and photolytic stress conditions. UPLC method was developed and validated for the analysis of vilanterol with its degradants. The drug was stable under photolytic and thermal stress conditions and degraded under acidic, basic, and oxidative stress conditions. Degradation kinetics was performed for acidic, basic and oxidative stress conditions. Kinetics parameters, K, half-life time (t1/2) and shelf-life time (t90) were assessed, and the degradation followed first order reaction. The method was linear from 0.10 to 100.00 µg mL-1 with accuracy, inter-day and intra-day precision from 99.45 to 100.02%, 0.391-0.694 and 0.041-0.345, respectively. Mass spectrometry was employed to elucidate the structure of the degradants, and the results revealed that certain degradation products were comparable to vilanterol metabolites. The World Anti-Doping Agency has prohibited the presence of vilanterol and its metabolites in athletes' urine except for exercise bronchoconstriction with limited dose. So, quantification of vilanterol in the presence of its degradants was performed in human urine. The results revealed that the method was linear in range of 1.00 to 100.00 µg mL-1. Samples collection and experimental protocol was performed according to the guidelines of the Research Ethics Committee of the Faculty of Pharmacy, the British University in Egypt with approval No. CH-2305.

Abstract
Given the prevalent use of inhaled beta2 -agonists in sports, there is an ongoing debate as to whether they enhance athletic performance. Over the last decades, inhaled beta2 -agonists have been claimed not to enhance performance with little consideration of dose or exercise modality. In contrast, orally administered beta2 -agonists are perceived as being performance enhancing, predominantly on muscle strength and sprint ability, but can also induce muscle hypertrophy and slow-to-fast fiber phenotypic switching. But because inhaled beta2 -agonists are more efficient to achieve high systemic concentrations than oral delivery relative to dose, it follows that the inhaled route has the potential to enhance performance too. The question is at which inhaled doses such effects occur. While supratherapeutic doses of inhaled beta2 -agonists enhance muscle strength and short intense exercise performance, effects at low therapeutic doses are less apparent. However, even high therapeutic inhaled doses of commonly used beta2 -agonists have been shown to induce muscle hypertrophy and to enhance sprint performance. This is concerning from an anti-doping perspective. In this paper, we raise awareness of the circumstances under which inhaled beta2 -agonists can constitute a performance-enhancing benefit.

Abstract
Nocturnal and early morning symptoms are common and uncomfortable in many patients with COPD, and are likely to affect their long-term outcomes. However, it is still debated whether it is better to give long-acting bronchodilators once- or twice-daily to symptomatic COPD patients. The functional link between circadian rhythms of autonomic tone and airway calibre explains why the timing of administration of bronchodilators in chronic airway diseases can induce different effects when taken at different biological (circadian) times. However, the timing also depends on the pharmacological characteristics of the bronchodilator to be used. Because the profile of bronchodilation produced by once-daily vs. twice-daily long-acting bronchodilators differs throughout 24 h, selecting long-acting bronchodilators may be customized to specific patient preferences based on the need for further bronchodilation in the evening. This is especially helpful for people who experience respiratory symptoms at night or early morning. Compared to placebo, evening bronchodilator administration is consistently linked with persistent overnight improvements in dynamic respiratory mechanics and inspiratory neural drive. The current evidence indicates that nocturnal and early morning symptoms control is best handled by a LAMA taken in the evening. In contrast, it seems preferable to use a LABA for daytime symptoms. Therefore, it can be speculated that combining a LAMA with a LABA can improve bronchodilation and control symptoms better. Both LAMA and LABA must be rapid in their onset of action. Aclidinium/formoterol, a twice-daily combination, is the most studies of the available LAMA/LABA combinations in terms of impact on daytime and nocturnal symptoms.

Abstract
Asthma has been recognised as a respiratory disorder for millennia and the focus of targeted drug development for the last 120 years. Asthma is one of the most common chronic non-communicable diseases worldwide. Chronic obstructive pulmonary disease (COPD), a leading cause of morbidity and mortality worldwide, is caused by exposure to tobacco smoke and other noxious particles and exerts a substantial economic and social burden. This chapter reviews the development of the treatments of asthma and COPD particularly focussing on the β-agonists, from the isolation of adrenaline, through the development of generations of short- and long-acting β-agonists. It reviews asthma death epidemics, considers the intrinsic efficacy of clinical compounds, and charts the improvement in selectivity and duration of action that has led to our current medications. Important β2-agonist compounds no longer used are considered, including some with additional properties, and how the different pharmacological properties of current β2-agonists underpin their different places in treatment guidelines. Finally, it concludes with a look forward to future developments that could improve the β-agonists still further, including extending their availability to areas of the world with less readily accessible healthcare.

Abstract
BACKGROUND In recent years, the combination of fluticasone furoate and vilanterol (FF/VI) has emerged as an alternative therapy, since it is administered every 24 h, in contrast to other ICS/LABAs such as fluticasone propionate plus salmeterol (FP/Salm), which requires administration every 12 h. Concerns have arisen over whether the benefit generated by FF/VI justifies the additional costs it involves over FP/Salm. This study aimed at assessing the health and economic consequences of FF/VI in patients with moderate-severe persistent asthma. METHODS A probabilistic Markov model was created to estimate the cost and quality-adjusted life-years (QALYs) of patients with persistent asthma. Total costs and QALYs for FF/VI and FP/Salm were calculated over a lifetime horizon. Multiple sensitivity analyses were conducted. Cost-effectiveness was evaluated at a willingness-to-pay value of $19,000. RESULTS We estimated a gain of 16.8 and 10.7 QALYs per patient per year on FF/VI and FP/Salm, respectively. At the same time, we observed a difference of US$216 in total discounted cost per person-year on FF/VI with respect to FP/Salm. The incremental cost-effectiveness ratio (ICER) of FF/VI was USD $70 per QALY with respect to FP/Salm. In the deterministic and probabilistic sensitivity analyses, our base-case results were robust to variations in all assumptions and parameters. CONCLUSION FF/VI is more cost-effective than FP/Salm. The evidence supports using FF/VI therapy in Colombia, and the study should be replicated in other middle-income countries.

Front Physiol 2023; 14:1131949. [PMID: 37179838 PMCID: PMC10170765 DOI: 10.3389/fphys.2023.1131949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 04/03/2023] [Indexed: 05/15/2023] Open
Abstract
Background: The Japanese drug use system allowed the once-daily use of inhaled corticosteroid fluticasone furoate (FF) combined with a long-acting beta-2 agonist vilanterol (VI) and a long-acting muscarinic antagonist umeclidinium (UMEC) against asthma on 18 February 2021. We investigated the real-world effects of these drugs (FF/UMEC/VI) mainly on lung function tests. Methods: This was an open-label, uncontrolled, within-group time-series (before-after) study. Prior asthma treatment (inhaled corticosteroid with/without a long-acting beta-2 agonist with/without a long-acting muscarinic antagonist) was switched to FF/UMEC/VI 200/62.5/25 μg. Subjects were evaluated by lung function tests prior to, and 1-2 months after, initiation of FF/UMEC/VI 200/62.5/25 μg. Patients were asked questions regarding the asthma control test and preference for drugs. Results: Overall, 114 asthma outpatients (97% Japanese) were enrolled from February 2021 to April 2022: 104 subjects completed the study. Forced expiratory volume in 1 s, peak flow, and asthma control test score of FF/UMEC/VI 200/62.5/25 μg-treated subjects were significantly increased (p < 0.001, p < 0.001, and p < 0.01, respectively). In contrast with FF/VI 200/25 μg, instantaneous flow at 25% of the forced vital capacity and expiratory reserve volume were significantly increased by FF/UMEC/VI 200/62.5/25 μg (p < 0.01, p < 0.05, respectively). Sixty-six percent of subjects declared they wanted to continue FF/UMEC/VI 200/62.5/25 μg in the future. Adverse effects, mainly local, were seen in 30% of patients, but no serious adverse effects were seen. Conclusion: Once-daily FF/UMEC/VI 200/62.5/25 μg was effective against asthma without serious adverse events. This is the first report that demonstrated FF/UMEC/VI dilated peripheral airways using lung function tests. This evidence on drug effects may improve our understanding of pulmonary physiology and the pathophysiology of asthma.

Effects of Adherence to Once-Daily Treatment on Lung Function, Bronchial Hyperreactivity and Health Outcomes in Adolescents with Mild-to-Moderate Asthmoka: A Twelve-Month Survey. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121854. [PMID: 36553298 PMCID: PMC9776553 DOI: 10.3390/children9121854] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 11/19/2022] [Accepted: 11/22/2022] [Indexed: 11/30/2022]
Abstract
Adolescents with asthma are usually insufficiently adherent to regular inhalation treatments, thus limiting their effectiveness. The aim of this study is to investigate the role of adherence to single-inhaler long-acting LABA/ICS dry-powder combination o.d. in affecting lung function, bronchial hyperreactivity, and health outcomes over a twelve-month survey of a group of non-smoking adolescents with mild to moderate asthma. Methods: Age, gender, BMI and atopy, forced expiratory volume in 1 s (FEV1), maximum mid-expiratory flow (MMEF), and maximum expiratory flow at 25% of lung filling (MEF25) were assessed via a Boolean selection process from the institutional database at recruitment, as well as after 6 and 12 months, together with the incidence of exacerbation, school days that were taken off, GP and specialist visits, and systemic steroid and/or antibiotic courses. Adherence was checked monthly via a direct telephone call. Statistics were calculated with an ANOVA trend analysis, assuming p < 0.05. Results: Two well-matched sample groups of 54 subjects each were obtained. The mean annual adherence to treatment ranged from 48.2% doses ± 10.9 sd to 79.3% doses ± 8.8 sd (p < 0.001), regardless of age and gender. Only adolescents that adhered to the o.d. ICS/LABA inhalation regimen progressively achieved complete control of all lung function parameters (FEV1: 0.001; MMEF: p < 0.002; MEF25 < 0.001; <0.001), minimized their bronchial hyperreactivity (p < 0.001), and optimized all health outcomes (p < 0.001—p < 0.002) over the survey duration. Discussion: A good adherence to treatment is essential for asthma management, particularly in young patients. Factors that are totally independent of the complexity of the therapeutic regimen adopted (namely, only a once-daily inhalation in the present survey) probably represent the major reasons limiting the adolescents’ adherence. Cultural, educational, behavioral, and psychological factors are frequently involved, are difficult to control, and can present barriers to adolescents’ asthma management. Further studies aiming to deeply understand and possibly remove the reasons for such adolescents’ attitudes are needed, in cooperation with actions oriented in this direction by families, educators, and health professionals.

Chest 2022; 163:799-814. [PMID: 36442662 DOI: 10.1016/j.chest.2022.11.027] [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: 05/17/2022] [Revised: 10/17/2022] [Accepted: 11/16/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Researchers have yet to obtain conclusive evidence differentiating among fixed-dose combinations (FDCs) of long-acting muscarinic antagonists (LAMAs) and long-acting beta-agonists (LABAs) for COPD in terms of real-world clinical outcomes. RESEARCH QUESTION What are the differences between available LAMA/LABA FDCs on the risk of acute exacerbation (AE) and cardiovascular events? STUDY DESIGN AND METHODS This retrospective cohort study based on a national insurance claims database included patients with COPD ≥ 40 years of age who were newly prescribed glycopyrronium (GLY)/indacaterol (IND), umeclidinium (UMEC)/vilanterol (VI), or tiotropium (TIO)/olodaterol (OLO) FDC between January 1, 2015, and June 30, 2019. Propensity score matching and Cox regression models were used to compare outcomes of AE and cardiovascular events associated with LAMA/LABA FDC treatment. RESULTS Among the 44,498 patients identified and included, 15,586 received GLY/IND, 20,460 received UMEC/VI, and 8,452 received TIO/OLO. Baseline characteristics were well balanced after 1:1 matching of UMEC/VI and GLY/IND, 2:1 matching of UMEC/VI and TIO/OLO, and 2:1 matching of GLY/IND and TIO/OLO. Risk of severe AE was lower among patients treated with UMEC/VI or GLY/IND than among those who received TIO/OLO (UMEC/VI vs TIO/OLO: 17.85 vs 29.32 per 100 person-years; hazard ratio, 0.76; 95% CI, 0.68-0.84; GLY/IND vs TIO/OLO: 15.54 vs 25.53 per 100 person-years; hazard ratio, 0.77; 95% CI, 0.67-0.88). In addition, GLY/IND users tended to have a lower risk of cardiovascular events than TIO/OLO users, but the difference dissipated when restricting follow up to a shorter duration. INTERPRETATION Our results revealed that the risk of severe AE was lower among patients with COPD receiving UMEC/VI or GLY/IND than among those receiving TIO/OLO, whereas the incidence of cardiovascular events was similar across groups but was slightly lower in GLY/IND users when compared with TIO/OLO users. Further research will be required to confirm these findings.

ICS/Ultra LABA in the Treatment of Obstructive Airway Diseases: A Consensus of Indian Experts. Adv Respir Med 2022; 90:407-424.

Abstract
Inhaled corticosteroid and ultra-long-acting beta-agonist (ICS/uLABA) combination is a recent advancement in the armamentarium against obstructive airways diseases (OADs). The combination of ICS/uLABA has several advantages, creating a favorable landscape for its utilization. Fluticasone furoate/vilanterol trifenatate (FF/Vi) is one such example of an ICS/uLABA. It offers several benefits from both drugs, such as a convenient once daily dosing schedule; high lipophilicity; high receptor affinity of fluticasone furoate along with high functional selectivity and a quick onset of action of vilanterol. However, the Global Initiative for Asthma (GINA) as well as the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines do not clearly define the positioning of ICS/uLABA compared to conventional ICS/LABAs. There are a few areas of uncertainty especially around the appropriate reliever strategy with ICS/uLABA in Asthma. The current consensus was planned with a group of Indian pulmonology experts to provide more clarity on the potential use of FF/Vi in Asthma and COPD. The clinical statements highlighted in this consensus manuscript address crucial clinical questions revolving around the efficacy and safety of FF/Vi as compared to conventional ICS/LABAs and identify the ideal patient profile for its use. This consensus paper also sheds light upon the appropriate reliever to be used along with FF/Vi in Asthma and the utilization of FF/Vi-based triple therapy in OADs. Expert recommendations mentioned in this paper will serve as guidance to pulmonologists as well as consultant physicians who are involved in providing care to OAD patients and will help them weigh the various factors that need to be taken into account while prescribing ICS/uLABA combination.

Abstract
Inhaled long-acting β-adrenergic agonists (LABAs) and short-acting β-adrenergic agonists are approved for the treatment of obstructive lung disease via actions mediated by β2 adrenergic receptors (β2-ARs) that increase cellular cAMP synthesis. This review discusses the potential of β2-AR agonists, in particular LABAs, for the treatment of acute respiratory distress syndrome (ARDS). We emphasize ARDS induced by pneumonia and focus on the pathobiology of ARDS and actions of LABAs and cAMP on pulmonary and immune cell types. β2-AR agonists/cAMP have beneficial actions that include protection of epithelial and endothelial cells from injury, restoration of alveolar fluid clearance, and reduction of fibrotic remodeling. β2-AR agonists/cAMP also exert anti-inflammatory effects on the immune system by actions on several types of immune cells. Early administration is likely critical for optimizing efficacy of LABAs or other cAMP-elevating agents, such as agonists of other Gs-coupled G protein-coupled receptors or cyclic nucleotide phosphodiesterase inhibitors. Clinical studies that target lung injury early, prior to development of ARDS, are thus needed to further assess the use of inhaled LABAs, perhaps combined with inhaled corticosteroids and/or long-acting muscarinic cholinergic antagonists. Such agents may provide a multipronged, repurposing, and efficacious therapeutic approach while minimizing systemic toxicity. SIGNIFICANCE STATEMENT: Acute respiratory distress syndrome (ARDS) after pulmonary alveolar injury (e.g., certain viral infections) is associated with ∼40% mortality and in need of new therapeutic approaches. This review summarizes the pathobiology of ARDS, focusing on contributions of pulmonary and immune cell types and potentially beneficial actions of β2 adrenergic receptors and cAMP. Early administration of inhaled β2 adrenergic agonists and perhaps other cAMP-elevating agents after alveolar injury may be a prophylactic approach to prevent development of ARDS.

Abstract
INTRODUCTION Asthma, a heterogeneous disease, is characterized by chronic airway inflammation and hyperreactivity. β2-adrenoreceptor agonists (β2-agonists) remain pivotal for asthma management. Short-acting β2-agonists (SABAs) result in rapid symptomatic alleviation and bronchospasm prevention. Patients experience significant clinical benefits from therapy with long-acting β2-agonists (LABAs) with efficacy to bronchodilate, and prolonged lung function betterment. Recently discovered β2-agonists with longer half-lives offer once-daily dosing. AREAS COVERED The authors provide a thorough review of the pharmacokinetics, pharmacodynamics, efficacy, tolerability, classification, and safety of β2-agonists through an in-depth review of current literature using these databases: U.S. National Institutes of Health's National Library of Medicine (NIH/NLM), PubMed Central, and NLM clinical trials. EXPERT OPINION β2- agonists act primarily on airway smooth muscle cells and are quintessential for adequate asthma management. Given their pharmacodynamic and pharmacokinetic properties, SABAs are used as rescue medication. Notably, the current Global Initiative for Asthma (GINA) strategy document recommends using LABA/inhaled corticosteroid combinations both as a daily controller and as a rescue medication. Clinicians should assess this new treatment plan on a per-case basis, making sure to evaluate inhaler adherence and treat modifiable risk factors. The development of next-generation β2- agonists is an exciting research area that could significantly improve patients' adherence to treatment regimens and, consequently, asthma control and quality of life.

Abstract
Treatment of obesity with repurposed or novel drugs is an expanding research field. One approach is to target beta2 -adrenergic receptors because they regulate the metabolism and phenotype of adipose and skeletal muscle tissue. Several observations support a role for the beta2 -adrenergic receptor in obesity. Specific human beta2 -adrenergic receptor polymorphisms are associated with body composition and obesity, for which the Gln27Glu polymorphism is associated with obesity, while the Arg16Gly polymorphism is associated with lean mass in men and the development of obesity in specific populations. Individuals with obesity also have lower abundance of beta2 -adrenergic receptors in adipose tissue and are less sensitive to catecholamines. In addition, studies in livestock and rodents demonstrate that selective beta2 -agonists induce a so-called 'repartitioning effect' characterized by muscle accretion and reduced fat deposition. In humans, beta2 -agonists dose-dependently increase resting metabolic rate by 10-50%. And like that observed in other mammals, only a few weeks of treatment with beta2 -agonists increases muscle mass and reduces fat mass in young healthy individuals. Beta2 -agonists also exert beneficial effects on body composition when used concomitantly with training and act additively to increase muscle strength and mass during periods with resistance training. Thus, the beta2 -adrenergic receptor seems like an attractive target in the development of anti-obesity drugs. However, future studies need to verify the long-term efficacy and safety of beta2 -agonists in individuals with obesity, particularly in those with comorbidities.

Abstract
Respiratory inflammation is caused by an air-mediated disease induced by polluted air, smoke, bacteria, and viruses. The COVID-19 pandemic is also a kind of respiratory disease, induced by a virus causing a serious effect on the lungs, bronchioles, and pharynges that results in oxygen deficiency. Extensive research has been conducted to find out the potent natural products that help to prevent, treat, and manage respiratory diseases. Traditionally, wider floras were reported to be used, such as Morus alba, Artemisia indica, Azadirachta indica, Calotropis gigantea, but only some of the potent compounds from some of the plants have been scientifically validated. Plant-derived natural products such as colchicine, zingerone, forsythiaside A, mangiferin, glycyrrhizin, curcumin, and many other compounds are found to have a promising effect on treating and managing respiratory inflammation. In this review, current clinically approved drugs along with the efficacy and side effects have been studied. The study also focuses on the traditional uses of medicinal plants on reducing respiratory complications and their bioactive phytoconstituents. The pharmacological evidence of lowering respiratory complications by plant-derived natural products has been critically studied with detailed mechanism and action. However, the scientific validation of such compounds requires clinical study and evidence on animal and human models to replace modern commercial medicine.

Abstract
PURPOSE Relvar® (Fluticasone furoate (FF)/Vilanterol (VI)) is a once-daily inhaler with bronchodilator effect lasting 24 hours. Our aim was to investigate the short- and long-term effects of FF/VI on exercise-induced asthma (EIA) in adolescents. METHODS Ninety-three adolescent asthmatics aged 12-18 years were referred for evaluation of EIA. Following a positive exercise challenge test (ECT), 22/44 were allocated to a single administration of salbutamol (400 μg) and 22/44 to FF/VI (92/22 μg) in a double-blind method. Thirty-five subjects were reassessed by repeat ECT 30-60 days of FF/VI. RESULTS Median FEV1 change post-ECT at baseline was -22.8% predicted (IQR -26.1 and -18.0) for salbutamol and -21.0 (IQR -30.7 and -16.8) for FF/VI. Following bronchodilator, FEV1 improved similarly in both groups. Repeat ECT following 30-60 days of FF/VI resulted in negative exercise challenge test in 33/35 subjects; the median decrease in FEV1 of these 35 subjects was 22.6% predicted (IQR 29-18) before, and 4.6% predicted (IQR 8.7-2.5) after 30-60 days of FF/VI treatment; p<0.0001). CONCLUSIONS FF/VI is effective in reversing EIA after 15 minutes in adolescents and in protecting EIA after 30-60 days in adolescents. Larger studies are needed to assess the effect of FF/VI on EIA.

Abstract
Introduction Inhaled β-agonists have been foundational medications for maintenance COPD management for decades. Through activation of cyclic adenosine monophosphate pathways, these agents relax airway smooth muscle and improve expiratory airflow by relieving bronchospasm and alleviating air trapping and dynamic hyperinflation improving breathlessness, exertional capabilities, and quality of life. β-agonist drug development has discovered drugs with increasing longer durations of action: short acting (SABA) (4-6 h), long acting (LABA) (6-12 h), and ultra-long acting (ULABA) (24 h). Three ULABAs, indacaterol, olodaterol, and vilanterol, are approved for clinical treatment of COPD. Purpose This article reviews both clinically approved ULABAs and ULABAs in development. Conclusion Indacaterol and olodaterol were originally approved for clinical use as monotherapies for COPD. Vilanterol is the first ULABA to be approved only in combination with other respiratory medications. Although there are many other ULABA's in various stages of development, most clinical testing of these novel agents is suspended or proceeding slowly. The three approved ULABAs are being combined with antimuscarinic agents and corticosteroids as dual and triple agent treatments that are being tested for clinical use and efficacy. Increasingly, these clinical trials are using specific COPD clinical characteristics to define study populations and to begin to develop therapies that are trait-specific.

Abstract
Bronchodilators, including long-acting β2-agonists and long-acting muscarinic antagonists, are the mainstay for treatment of patients with chronic obstructive pulmonary disease (COPD) to prevent exacerbations or reduce symptoms. Formoterol is a highly selective and potent β2-agonist that relaxes airway smooth muscle to significantly improve lung function. Inhaled formoterol works within 5 minutes of administration and provides improvements in spirometry measurements over 12 hours. The lipophilicity of formoterol allows it to form a depot within the smooth muscle to provide a prolonged duration of action. Following therapeutic doses, plasma concentrations are very low or undetectable. Determination of the pharmacokinetics of formoterol following high-dose administration to healthy volunteers revealed that the drug was rapidly absorbed and excreted unchanged in the urine with a half-life of 10 hours. Inhaled formoterol, as monotherapy or in combination with other agents, is an effective and safe treatment option for patients with moderate to severe COPD. Clinical studies have demonstrated improvements in lung function and COPD symptoms, particularly dyspnea; reductions in the risk of exacerbations; and improvement in patients' health status. The adverse event profile of inhaled formoterol is similar to that of placebo, with few adverse cardiovascular events. Formoterol is a valuable bronchodilator used in the maintenance treatment of COPD. This review describes the mechanism of action, pharmacodynamics, and pharmacokinetics of inhaled formoterol. It also reviews the results of large, randomized, controlled clinical trials that evaluated the use of formoterol as monotherapy and in combination with inhaled corticosteroids, long-acting muscarinic antagonists, and triple therapy regimens in the treatment of patients with moderate to severe COPD.

Abstract
Research using animal models of asthma is currently dominated by mouse models. This has been driven by the comprehensive knowledge on inflammatory and immune reactions in mice, as well as tools to produce genetically modified mice. Many of the identified therapeutic targets influencing airway hyper-responsiveness and inflammation in mouse models, have however been disappointing when tested clinically in asthma. It is therefore a great need for new animal models that more closely resemble human asthma. The guinea pig has for decades been used in asthma research and a comprehensive table of different protocols for asthma models is presented. The studies have primarily been focused on the pharmacological aspects of the disease, where the guinea pig undoubtedly is superior to mice. Further reasons are the anatomical and physiological similarities between human and guinea pig airways compared with that of the mouse, especially with respect to airway branching, neurophysiology, pulmonary circulation and smooth muscle distribution, as well as mast cell localization and mediator secretion. Lack of reagents and specific molecular tools to study inflammatory and immunological reactions in the guinea pig has however greatly diminished its use in asthma research. The aim in this position paper is to review and summarize what we know about different aspects of the use of guinea pig in vivo models for asthma research. The associated aim is to highlight the unmet needs that have to be addressed in the future.

Abstract
The topic of 24-hour management of COPD is related to day-to-night symptoms management, specific follow-up and patients’ adherence to therapy. COPD symptoms strongly vary during day and night, being worse in the night and early morning. This variability is not always adequately considered in the trials. Night-time symptoms are predictive of higher mortality and more frequent exacerbations; therefore, they should be a target of therapy. During night-time, in COPD patients the supine position is responsible for a different thoracic physiology; moreover, during some sleep phases the vagal stimulation determines increased bronchial secretions, increased blood flow in the bronchial circulation (enhancing inflammation) and increased airway resistance (broncho-motor tone). Moreover, in COPD patients the circadian rhythm may be impaired. The role of pharmacotherapy in this regard is still poorly investigated. Symptoms can be grossly differentiated according to the different phenotypes of the disease: wheezing recalls asthma, while dyspnea is strongly related to emphysema (dynamic hyperinflation) or obstructive bronchiolitis (secretions). Those symptoms may be different targets of therapy. In this regard, GOLD recommendations for the first time introduced the concept of phenotype distinction suggesting the use of inhaled corticosteroids (ICS) particularly when an asthmatic pattern or eosiophilic inflammations are present, and hypothesized different approaches to target symptoms (ie, dyspnea) or exacerbations. Pharmacotherapy should be evaluated and possibly directed on the basis of circadian variations, for instance, supporting the use of twice-daily rapid-action bronchodilators and evening dose of ICS. Recommendations on day and night symptoms monitoring strategies and choice of the specific drug according to patient’s profile are still not systematically investigated or established. This review is the summary of an advisory board on the topic “24-hour control of COPD and role of pharmacotherapy”, held by five pulmonologists, experts in respiratory pathophysiology, pharmacology and sleep medicine. ![]()

Abstract
Background This study evaluated the efficacy of switching therapy from fluticasone propionate/salmeterol (FP/SM) or budesonide/formoterol (BD/FM) to fluticasone furoate and vilanterol (FF/VI) at the equivalent corticosteroid dose in a real-world setting. Methods A prospective, 3-month, open-label, parallel group, switching therapy trial was performed in symptomatic asthma patients under routine management. Patients using 1 puff of FP 250 µg/SM 50 µg b.i.d or 2 puffs of BD 160 µg/FM 4.5 µg b.i.d were switched to FF 100 µg/VI 25 µg once daily, while patients using 1 puff of FP 500 µg/SM 50 µg b.i.d or 4 puffs of BD 160/FM b.i.d was switched to FF 200 µg/VI 25 µg once daily. The primary outcome was improvement of the predicted forced expiratory volume in 1 second % (%FEV1), while secondary outcomes were improvement of asthma symptoms evaluated by the asthma control test (ACT) and fractional exhaled nitric oxide (FeNO). Results The %FEV1 was improved at 4 weeks after switching, and the improvement was maintained until 12 weeks. ACT also improved after switching. Patients with ACT <20 before switching showed greater improvement of symptoms at 4 weeks and 62% had an ACT score >20. FeNO decreased from 8 weeks. Conclusions In symptomatic asthma patients showing insufficient control, improvement of asthma was obtained by switching to FF/VI at the equivalent corticosteroid dose accompanied with the improvement of biomarkers. FF/VI can be a useful option for better control of asthma because of its high efficacy, long duration of action, and delivery via a single-action device.

Abstract
Asthma is a heterogeneous inflammatory disease of the airways that is associated with airway hyperresponsiveness and airflow limitation. Although asthma was once simply categorized as atopic or nonatopic, emerging analyses over the last few decades have revealed a variety of asthma endotypes that are attributed to numerous pathophysiological mechanisms. The classification of asthma by endotype is primarily routed in different profiles of airway inflammation that contribute to bronchoconstriction. Many asthma therapeutics target G protein-coupled receptors (GPCRs), which either enhance bronchodilation or prevent bronchoconstriction. Short-acting and long-acting β 2-agonists are widely used bronchodilators that signal through the activation of the β 2-adrenergic receptor. Short-acting and long-acting antagonists of muscarinic acetylcholine receptors are used to reduce bronchoconstriction by blocking the action of acetylcholine. Leukotriene antagonists that block the signaling of cysteinyl leukotriene receptor 1 are used as an add-on therapy to reduce bronchoconstriction and inflammation induced by cysteinyl leukotrienes. A number of GPCR-targeting asthma drug candidates are also in different stages of development. Among them, antagonists of prostaglandin D2 receptor 2 have advanced into phase III clinical trials. Others, including antagonists of the adenosine A2B receptor and the histamine H4 receptor, are in early stages of clinical investigation. In the past decade, significant research advancements in pharmacology, cell biology, structural biology, and molecular physiology have greatly deepened our understanding of the therapeutic roles of GPCRs in asthma and drug action on these GPCRs. This review summarizes our current understanding of GPCR signaling and pharmacology in the context of asthma treatment. SIGNIFICANCE STATEMENT: Although current treatment methods for asthma are effective for a majority of asthma patients, there are still a large number of patients with poorly controlled asthma who may experience asthma exacerbations. This review summarizes current asthma treatment methods and our understanding of signaling and pharmacology of G protein-coupled receptors (GPCRs) in asthma therapy, and discusses controversies regarding the use of GPCR drugs and new opportunities in developing GPCR-targeting therapeutics for the treatment of asthma.

Abstract
:
Triple inhaled therapy for Chronic Obstructive Pulmonary Disease (COPD) includes an
inhaled corticosteroid (ICS), a long-acting b2-agonist (LABA) and a long-acting muscarinic
antagonist (LAMA) taken in combination. Triple therapy is recommended by the Global Initiative for
Chronic Obstructive Lung Disease (GOLD) for patients who experience recurrent exacerbations
despite treatment with either a dual bronchodilator or LABA/ICS combination. There is consistent
evidence that the LABA/LAMA/ICS combination has significantly greater effects on trough FEV1,
symptoms, quality of life, and exercise performance compared to comparator treatments.
:
The role of triple therapy in reducing exacerbations in COPD patients is debatable, but recent trials
have revealed some intriguing insights.
:
Three pivotal studies, namely TRILOGY, TRINITY and TRIBUTE have been conducted to evaluate
the safety and efficacy of extrafine Beclomethasone/Formoterol Fumarate/Glycopyrronium Bromide
(BDP/FF/GB) versus different treatment options for COPD. Extrafine BDP/FF/GB has been
compared to an ICS/LABA (BDP/FF) combination in the TRILOGY study, to a LAMA
monotherapy (Tiotropium-TIO) and an extemporary triple combination of ICS/LABA + LAMA
(BDP/FF + TIO) in the TRINITY study, and to one inhalation of LABA/LAMA per day (Indacaterol/
Glycopyrronium - IND/GLY) in the TRIBUTE study.
:
Another triple therapy with Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI) was
recently tested in two further studies that included patients with COPD. The FULFIL study compared
the efficacy of the triple FF/UMEC/VI therapy to the ICS/LABA association budesonide/formoterol,
while the IMPACT study compared the rate of moderate and severe exacerbations between singleinhaler
FF/UMEC/VI and single-inhaler FF/VI or UMEC/VI.

Abstract
Fluticasone furoate (FF) and vilanterol trifenatate (VT) is a widely prescribed combination in the management of asthma and chronic obstructive pulmonary disease. In the present study, two quantitative methods based on HPLC-UV and spectrofluorimetric analysis had been developed and validated for simultaneous estimation of FF and VT in rabbit plasma using baclomethasone as internal standard (ISTD). Analytes and ISTD were separated from plasma using simple step of protein precipitation with acetonitrile. Chromatographic separation was achieved on Spherisorb S5 ODS2 (250 mm × 4.6 mm, 5.0 µm) column using mobile phase that constitute acetonitrile-0.01% glacial acetic acid in water (70:30, v/v) and then detected on a UV detector at 235 nm wavelength. Spectrofluorimetric detection was performed using absorption/emission wavelength (λabs/em) of 286/352 nm and 362/407 nm for FF and VT, respectively. For both analytes, linearity ranged from 4-200 ng/mL to 10-200 ng/mL using HPLC-UV and spectrofluorimetric method, respectively. Methods were validated as per FDA recommendations. Statistical analysis revealed that these detection methods are statistically insignificant difference and can be used interchangeably without any bias. Further, these methods were applied in pharmacokinetic study for simultaneous estimation of FF and VT in rabbit plasma.

Once-daily fluticasone furoate/vilanterol combination versus twice-daily budesonide/formoterol combination in the treatment of controlled stable asthma: a randomized crossover trial. J Asthma Allergy 2019; 12:253-261. [PMID: 31571932 PMCID: PMC6756272 DOI: 10.2147/jaa.s223093] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2019] [Accepted: 09/03/2019] [Indexed: 11/23/2022] Open
Abstract
Introduction Fluticasone furoate (FF)/vilanterol (VI) dry powder inhaler (DPI) is the only once-daily maintenance inhaled corticosteroid (ICS)/long-acting β2 adrenergic agonist (LABA) combination for asthma. We aimed to compare the clinical effects of once-daily FF/VI and twice-daily budesonide (BUD)/formoterol (FM) DPI in patients with controlled stable asthma. Methods We performed a randomized crossover trial in which stable asthmatic patients controlled on ICS/LABA received 8 weeks of FF/VI (100/25 μg 1 puff once-daily) or BUD/FM (160/4.5 μg 2 puffs twice-daily) DPI treatment. After a 4–8-week washout period, patients received another crossover treatment for 8 weeks. We assessed pulmonary function, the 5-item version asthma control questionnaire (ACQ5), the asthma control test (ACT), and fractional exhaled nitric oxide (FeNO) at baseline and after 8 weeks of treatment (week 8). As the primary outcome was change in force expiratory volume in 1 s (FEV1) between baseline and week 8, we evaluated the incidence of asthma exacerbation and adherence barrier questionnaire (Ask-12) at week 8. Results Twenty-three patients were initially enrolled in this study; however, one patient had to be excluded. The FF/VI DPI treatment group showed a similar magnitude of change in FEV1 between baseline and week 8 as the BUD/FM DPI treatment group. In addition, there were no significant differences in pulmonary function tests, ACQ5 scores, ACT scores, and FeNO between baseline and week 8 in both groups. Although the incidence of exacerbation did not differ between groups, the Ask-12 score in the FF/VI DPI group was significantly lower than that in the BUD/FM DPI group. Conclusions The present study indicates that once-daily FF/VI DPI is not inferior to twice-daily BUD/FM DPI in clinical effect and more likely to improve inconvenience and forgetfulness in inhalation adherence barriers for stable asthma control therapy. Once-daily FF/VI DPI may be an effective alternative for asthma maintenance treatment.

Abstract
BACKGROUND β2-adrenoreceptors have recently been identified as regulators of the α-synuclein gene, which is implicated in the pathogenesis of Parkinson's disease. OBJECTIVE The objectives of this study were to assess the association between use of β2-agonists and β-antagonists and the risk of developing PD. METHODS We conducted a nested case-control study in a cohort of 1,762,164 adults without a diagnosis of PD. They were identified on January, 1, 2004, from the electronic medical records of the largest health care provider in Israel. Participants were followed up until June 30, 2017, for the occurrence of PD. Ten randomly selected controls were matched to each case of PD on age, sex, ethnic group, and duration of follow-up. RESULTS During follow-up 11,314 patients were newly diagnosed with PD and were matched with 113,140 controls. An increased risk of PD was seen with the use of nonselective β-antagonists (RR, 2.04 [1.90-2.20]) but not with the use of selective β1-antagonists (RR, 1.00 [0.95-1.05]). Use of β2-agonists was associated with reduced risk of PD (RR, 0.89 [0.82-0.96] for short-acting; RR, 0.84 [0.76-0.93] for long-acting; and RR, 0.49 [0.25-0.92] for ultra-long-acting β2-agonists). In an analysis of individual drugs, propranolol and salbutamol were significantly associated with PD risk, even when these drugs were ascertained 5 years prior to the index date, compared with nonusers (RR, 1.31 [1.08-1.58] and 1.89 {1.53-2.33]) in patients who filled <6 and ≥6 propranolol prescriptions, respectively; the corresponding RRs for salbutamol were 0.95 (0.83-1.08) and 0.65 (0.45-0.94), respectively. CONCLUSIONS Use of propranolol appears to be associated with an increased risk of PD, whereas use of β2-agonists is associated with a decreased risk of PD. © 2018 International Parkinson and Movement Disorder Society.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common respiratory disease that is predicted to be one of the leading causes of death worldwide. Pharmacologic treatment options of COPD are bronchodilators, using either long-acting β2-agonists (LABAs), or long-acting muscarinic antagonists (LAMAs), or a combination of two. Anoro Ellipta (umeclidinium + vilanterol) dry powder inhaler, a fixed-dose combination of LAMA and LABA, was Food and Drug Administration (FDA) approved in 2013 for COPD. The objective of this study is to evaluate the efficacy and safety of once daily umeclidinium/vilanterol (62.5 mcg/25 mcg) in COPD patients, focusing on pharmacodynamic and pharmacokinetic characteristics, efficacy and safety in clinical studies and cost. Literature search was done through PubMed (2004-2017) using the terms umeclidinium, vilanterol, COPD, LABA and LAMA. Recent and significant clinical trials about the monocomponents and their combination were identified, in addition to reviews, guidelines for COPD, data from manufacturer and FDA product labels. The search was limited to English language studies on human subjects. Clinical data published on the combination of umeclidinium/vilanterol in patients with COPD have shown greater improvements in lung function compared to monotherapies. However, further studies comparing umeclidinium/vilanterol FDC (ANORO) to other LABA/LAMA combinations are needed.

Ultra-LABAs for the treatment of asthma. Respir Med 2019; 156:47-52.

Abstract
The term ultra-LABA indicates once-daily β2-AR agonists (abediterol, indacaterol, olodaterol and vilanterol) that are single enantiomers of the (R)-configuration. All have a near full-agonist profile at human β2-AR. They can be prescribed in asthmatics only when associated with an with ICS, although further confirmations need to clarify what really these agents add if used in association to ICS and in what asthmatic patients this association may have more value. They are also under development in triple inhalers that include an ultra-LABA, a LAMA and an ICS. The once-daily posology might increase adherence in long-term treatment of asthma but superiority to twice-daily LABAs has not yet been fully demonstrated. In any case, still no ultra-LABA can be recommended as preferred.

Abstract
Vilanterol trifenatate is a novel chiral long-acting β2-agonist developed. Vilanterol combined with inhaled corticosteroids can treat COPD and asthma. A simple liquid chromatographic method is developed for the quantitative determination of R-vilanterol and S-vilanterol (impurity S). HPLC separation was achieved on Chiralpak ID (250 × 4.6 mm; particle size 5 μm) column using hexane-ethanol-ethanolamine (75:25:0.1, v/v/v) as mobile phase at a flow rate of 1.0 mL/min. The resolution is greater than 3.3. Ethanolamine in the mobile phase is vital to enhance chromatographic efficiency and resolution between the isomers. The method was validated with respect to accuracy, specificity, precision, LOD, LOQ, linearity, and robustness as ICH guidelines.

Abstract
OBJECTIVE Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is of increasing interest because ACO patients have significantly worse outcomes, leading to greater social and economic burdens compared with asthma or COPD alone. Some guidelines for ACO recommend triple therapy with inhaled corticosteroids, long-acting β2 agonists, and long-acting muscarinic antagonists. However, this approach is based on extrapolating data from patients with asthma or COPD alone. Therapeutic studies for ACO have not previously been conducted. MATERIALS AND METHODS A 12-week, randomized, open-label cross-over pilot study was conducted in 17 ACO patients to evaluate the effect of umeclidinium (UMEC) 62.5 µg once-daily added to fluticasone furoate/vilanterol (FF/VI) 200/25 µg once-daily. A 4-week run-in, a first and a second 4-week treatment period were included. Respiratory function, respiratory impedance, fractional exhaled nitric oxide, COPD assessment test, and asthma control test scores were evaluated 0, 4, and 8 weeks after randomization. RESULTS Mean values of post-bronchodilator forced expiratory volume in 1 second as a percentage of the predicted value (%FEV1), after UMEC was added to FF/VI, were significantly higher than after the run-in (p < 0.01). Mean values of resonant frequency during inspiration (Fres), after UMEC was added to FF/VI, were significantly lower than after the run-in (p < 0.01). CONCLUSION Adding UMEC to FF/VI provides greater improvement in lung function, indicating that triple therapy is a suitable regular treatment for ACO.

Abstract
Background: Fluticasone furoate/vilanterol (FF/V) is an effective long-acting β2 agonist/inhaled corticosteroid combination for managing persistent bronchial asthma. The aim of the study was to assess the outcomes achievable in patients with mild to moderate asthma receiving FF/V 92/22 µg once daily for 12 months. Methods: Data were automatically and anonymously obtained from the institutional database: forced expiratory volume in 1 s predicted values; the exacerbation and hospitalization rates; days of hospitalization; general practitioner (GP) or specialist visits; days of inactivity; courses of systemic steroids or antibiotics were recorded at baseline and after 3, 6 and 12 months of treatment. The overall adherence to treatment was also calculated. Analysis of variance was used for checking the trends of variables. The improvement in lung function was significant (p < 0.001) and time dependent. The mean (±standard error) exacerbation rate per patient changed from 1.05 (±0.16) at baseline to 0.28 (±0.07) after 3 months, 0.33 (±0.08) after 6 months and 0.18 (±0.08) after 12 months (p < 0.001). The mean hospitalization rate per patient changed from 0.30 (±0.07) at baseline to 0.08 (±0.04) after 3 months, 0.10 (±0.05) after 6 months and 0.03 (±0.03) after 12 months (p < 0.001). Also mean duration of hospitalization and days of inactivity were reduced over time (p < 0.001). GP visits were also reduced, together with specialist visits (both p < 0.001). Steroid and antibiotic courses dropped significantly (p < 0.001 and p < 0.001, respectively). Moreover, changes in all outcomes considered proved time dependent, particularly over the second semester. Finally, over time, adherence to treatment was high. Conclusions: The once-daily inhalation of combined FF/V 92/22 µg optimized systematically the exacerbation and hospitalization rates in mild to moderate asthma, together with all other outcomes over time. The effectiveness of FF/V 92/22 µg once daily proved to be time dependent over the period of the study.

Abstract
Background and purpose Fixed-dose combinations of a long-acting beta agonist and an inhaled corticosteroid are more effective than the individual components in COPD. The primary study objective was to demonstrate that the combination indacaterol acetate/mometasone furoate (IND/MF [QMF149]) was non-inferior to the twice-daily combination salmeterol xinafoate/fluticasone propionate (Sal/Flu) in terms of trough FEV1 at week 12 (day 85). Secondary objectives were to compare the efficacy of IND/MF (QMF149) vs Sal/Flu with respect to other lung function parameters, COPD exacerbations, symptoms and dyspnea, health status/health-related quality of life, and rescue medication use. Materials and methods This was a 12-week multicenter, randomized, double-blind, double-dummy, parallel-group, Phase II study in patients with moderate-to-very-severe COPD, who were randomized (1:1) to IND/MF (QMF149) (150/160 µg once daily; n=316) or Sal/Flu (50/500 µg twice daily; n=313). Results Over 90% of patients completed the study: 94.6% in the IND/MF (QMF149) group and 92.0% in the Sal/Flu group. The primary objective of non-inferiority of IND/MF (QMF149) to Sal/Flu for trough FEV1 at week 12 (day 85) was met: the lower limit of the CI (95% CI: 27.7, 83.3 mL) was greater than −60 mL. The analysis for superiority of IND/MF (QMF149) to Sal/Flu demonstrated superiority of IND/MF (QMF149), with a difference of 56 mL (P<0.001). In addition, IND/MF (QMF149) treatment significantly improved COPD exacerbation-related parameters during the 12-week period. Other significant improvements with IND/MF (QMF 149) vs Sal/Flu were noted for dyspnea at week 12 and other COPD symptoms and COPD rescue medication use over the 12 weeks. The safety and tolerability profiles of both the treatments were similar.

Abstract
OBJECTIVES The aim of this study was to assess the current evidence for long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combinations (FDCs) in the treatment of COPD. MATERIALS AND METHODS A systematic literature search of randomized controlled trials published in English up to September 2017 of LABA/LAMA FDCs vs LABA or LAMA or LABA/inhaled corticosteroid (ICS) FDCs in COPD patients was performed using PubMed, Embase, Scopus, and Google Scholar. Outcomes including forced expiratory volume in 1 second (FEV1), Transition Dyspnea Index (TDI) scores, St George's Respiratory Questionnaire (SGRQ) scores, exacerbations, exercise tolerance (endurance time [ET]), inspiratory capacity (IC), and rescue medication use were evaluated. RESULTS In total, 27 studies were included in the review. LABA/LAMA FDCs significantly improved lung function (FEV1) at 12 weeks compared with LABA or LAMA or LABA/ICS. These effects were maintained over time. Significant improvements with LABA/LAMA FDCs vs each evaluated comparator were also observed in TDI and SGRQ scores, even if significant differences between different LABA/LAMA FDCs were detected. Only the LABA/LAMA FDC indacaterol/glycopyrronium has shown superiority vs LAMA and LABA/ICS for reducing exacerbation rates, while olodaterol/tiotropium and indacaterol/glycopyrronium have been shown to improve ET and IC vs the active comparators. Rescue medication use was significantly reduced by LABA/LAMA FDCs vs the evaluated comparators. LABA/LAMA FDCs were safe, with no increase in the risk of adverse events with LABA/LAMA FDCs vs the monocomponents. CONCLUSION Evidence supporting the efficacy of LABA/LAMA FDCs for COPD is heterogeneous, particularly for TDI and SGRQ scores, exacerbation rates, ET, and IC. So far, indacaterol/glycopyrronium is the LABA/LAMA FDC that has the strongest evidence for superiority vs LABA, LAMA, and LABA/ICS FDCs across the evaluated outcomes. LABA/LAMA FDCs were safe; however, more data should be collected in a real-world setting to confirm their safety.

Abstract
BACKGROUND Fluticasone furoate/Vilanterol trifenatate (FF/VI) is an inhaled corticosteroid/long-acting beta-agonist combination with a prolonged bronchodilator duration of action. We characterised the time-course of onset and offset of airway anti-inflammatory action of FF/VI, as assessed by fraction of exhaled nitric oxide (FeNO), and compared this to the bronchodilator duration of action. METHODS A single-centre, randomised, double-blind, placebo-controlled, two-period, crossover study was undertaken in 28 steroid-naïve adults with asthma. Participants with an FEV1 ≥ 60% predicted, reversible airway disease, and FeNO > 40 ppb received FF/VI 100/25 mcg or placebo once daily for 14 days. FeNO and peak expiratory flow were measured twice-daily during treatment and during a 21-day washout period. FEV1 was measured for five days from treatment cessation. The primary outcome measure was FeNO change from baseline ratio for 21 days following treatment cessation. RESULTS In the 27 subjects who completed the study, median (range) baseline FeNO was 87 ppb (42-212). FF/VI 100/25 mcg reduced FeNO by day 3, ratio FF/VI versus placebo 0.72 (95% confidence interval 0.61-0.86) with the maximum reduction occurring at day 14, 0.32 (0.27-0.37). Following cessation of treatment FeNO remained suppressed for 18 days, ratio on day 18 0.77 (0.59-1.00), whereas improvements in FEV1 and peak flow were maintained for 3 to 4 days post-treatment. CONCLUSIONS The anti-inflammatory duration of action of FF/VI is consistent with the high glucocorticoid receptor affinity and long lung retention of fluticasone furoate. The anti-inflammatory effect of FF/VI was of greater duration than its bronchodilator effect in adults with mild asthma. Funding GlaxoSmithKline (201499).

Abstract
BACKGROUND Ultra-long-acting β2 agonists (uLABA) are relatively new anti-asthma medications of which there are three different formulations currently available: olodaterol, indacaterol, and vilanterol. The first 2 formulations have been shown to exert bronchoprotective effects; they are able to prevent airway smooth muscle contraction on exposure to constricting stimuli. However, studies have found that these 2 drugs produce different degrees and durations of bronchoprotection against methacholine. OBJECTIVE The objective of this study was to investigate the degree of bronchoprotection provided by vilanterol against methacholine-induced bronchoconstriction. METHODS Fourteen patients with mild-to-moderate asthma (8 male; baseline percent predicted forced expiratory volume in 1 second [FEV1] > 65%; provocative concentration of methacholine causing a 20% reduction in FEV1 [PC20] ≤ 8 mg/mL) completed this randomized, double-blind, 3-way crossover study. Methacholine challenges were performed before treatment administration (placebo, 100 μg fluticasone furoate, or 25 μg vilanterol + 100 μg fluticasone furoate) and at 0.5 and 24 hours posttreatment. Each treatment arm was separated by a minimum 7-day washout period. A combination therapy of vilanterol+fluticasone furoate was used, because vilanterol is not available as a monotherapy. RESULTS Significant bronchoprotection was evident after the combination treatment at both 0.5 and 24 hours with doubling dose shifts in methacholine PC20 of 2.0 (P = .0004) and 1.6 (P = .0001), respectively. Clinically significant bronchodilation was only recorded at 24 hours after combination treatment (P < .05). CONCLUSION These findings suggest that vilanterol (in combination with fluticasone furoate) provides significant bronchoprotection against methacholine-induced bronchoconstriction for at least 24 hours in patients with mild-to-moderate asthma.

Abstract
Background Bronchial asthma is an inflammatory disease of the airways. Beclomethasone dipropionate/Formoterol (BDP/F) and Fluticasone furoate/Vilanterol (FF/V) are two of the most effective LABA/ICS combinations for managing persistent bronchial asthma. Aim of the study was to compare the outcomes achieved in mild-to-moderate asthma patients assuming BDP/F 100/6 μg b.i.d. (Group A) or FF/V 92/22 μg once-daily (Group B) for 12-months. No head-to-head long-term comparison is available at present. Methods Data were automatically and anonymously obtained from the institutional database: FEV1% predicted values; the exacerbation and hospitalization rates; days of hospitalization; GP and/or specialist visits; days of inactivity; courses of systemic steroids and/or antibiotics were recorded at baseline and after 3, 6 and 12 months of both treatments. The overall adherence to treatments was also calculated. The propensity score method was used for matching and comparing the two cohorts of patients; Anova and Wilcoxon tests were used for checking the trends and time-to-time comparisons over the period; statistical significance was accepted for p < 0.05. Results The PS-matching process returned a cohort of 40 group A patients matched with 40 patients of group B, fully comparable for demographics, clinical characteristics, and comorbidities. The improvement in lung function was significant in both groups (p < 0.001), even if it was significantly higher and time-dependent in group B. The mean (±SE) exacerbation rate/patient changed from 0.63 (±0.13) at baseline to 0.53 (±0.12) after three; to 0.58 (±0.13) after six, and to 0.60 (±0.18) after twelve months in group A (p = ns), while from of 1.05 (±0.16) at baseline, to 0.28 (±0.07) after three; to 0.33 (±0.08) after six, and to 0.18 (±0.08) after twelve months in group B (p < 0.001), respectively. The mean hospitalization rate/patient changed from 0.25 ± 0.07 at baseline to 0.15 (±0.06) after three; to 0.08 (±0.04) after six, and to 0.13 (±0.05) after twelve months in group A (p = ns), while from 0.30 (±0.07) at baseline to 0.08 (±0.04) after three; to 0.10 (±0.05) after six, and to 0.03 (±0.03) after twelve months in group B (p < 0.001), respectively. Also mean duration of hospitalization and days of inactivity were in favour of FF/V treatment over time (in both cases p < 0.001). GP’s visits were reduced by both treatments (p < 0.007 in group A and p < 0.001 in group B, respectively, while Specialist’s visits only dropped during FF/V (p < 0.001). Steroid and antibiotic courses were significantly reduced by both treatments, even if more systematically in group B (p < 0.001 vs p < 0.007, and p < 0.001 vs p < 0.044, respectively). Moreover, changes in all outcomes considered proved time-dependent during the FF/V treatment only, particularly over the second semester. Finally, the overtime adherence to treatment was higher by 22 days during FF/V . Conclusions Both the ICS/LABA combinations proved effective, even if characterized by different patterns of effectiveness either in terms of lung function and of long-term clinical outcomes. Only the once-daily inhalation of combined FF/V 92/22 μg once-daily optimized systematically the exacerbation and hospitalization rates in mild-to-moderate asthma, together with all other outcomes over time. The effectiveness of FF/V 92/22 once-daily μg proved progressive and time-dependent over the twelve-month period of the study, and associated to a higher adherence to treatment.

Abstract
Inhaled administration is underutilised because the drug discovery process is viewed as challenging, risky, and expensive. However, unmet medical need continues to grow, and significant opportunities exist to discover novel inhaled medicines delivering the required lung concentrations while minimising systemic exposure. This profile could be achieved by a combination of properties, including lung retention and low oral bioavailability. Property-based rules exist for orally administered compounds, but there has been limited progress defining in silico predictors to guide the discovery of novel inhaled drugs. Recently, the use of informative cell- and tissue-based screens has greatly facilitated the identification of compounds with optimal characteristics for inhaled delivery. Here, we address opportunities for novel inhaled drugs, and the key challenges and uncertainties hampering progress.

Abstract
This study describes the association rate and residence time of abediterol, a novel long-acting β2-adrenoceptor agonist (LABA) in Phase II development for treatment of asthma and COPD, in comparison with indacaterol, olodaterol, vilanterol and salmeterol, for both human β1- and β2-adrenoceptors. Abediterol association and dissociation rates were monitored directly by using its tritiated form. Moreover, association was determined indirectly using experimental Ki and koff obtained from assays performed with unlabelled compound. Dissociation was also studied indirectly by measuring the association rate of 3H-CGP12177 to beta adrenoceptors previously occupied by unlabelled compounds. Abediterol shows a fast association for the β2-adrenoceptor (kon 1.4 × 107 ± 1.8 × 106M-1min-1) while its dissociation rate is between 30 and 64 times slower than that of the reference LABA compounds tested, with a residence time of 91.3 ± 13.3min (measured directly) and 185.5 ± 7.5min (measured indirectly). Abediterol shows kinetic selectivity for the β2- over the β1-adrenoceptor, with a dissociation rate from the β1-adrenoceptor similar to the other LABA compounds tested. In conclusion, abediterol is a potent LABA with a fast association rate and a long residence time at β2-adrenoceptors. These data are in agreement with the onset and duration of action of abediterol shown in humans.

Abstract
INTRODUCTION The current GOLD (Global Initiative for Chronic Obstructive Lung Disease) recommendations suggest using long acting β2 agonists (LABA) and long acting muscarinic antagonists (LAMA) in combination for group B COPD patients with persistent symptoms, group C COPD patients with further exacerbations on LAMA therapy alone and for group D COPD patients with or without combination with inhaled corticosteroids (ICS). Thus, there is a lot of interest in developing LABA/LAMA combinations for maintenance therapy of chronic stable COPD. Areas covered: Many LABA/LAMA combinations have successfully been approved through carefully designed pivotal clinical trials. The current clinical use of LABA/LAMA combinations in COPD will continue to evolve as new trials with and without inhaled corticosteroids are completed. Expert opinion: Combining different classes of bronchodilators in a single inhaler is an attractive concept that can potentially improve patient adherence to therapy. Because LABA/LAMA combinations are the preferred treatment option for preventing COPD exacerbations in the updated GOLD guidelines for COPD, they will be clinically used. Future treatment of COPD should revolve around a personalized approach based on characterization of the COPD phenotype.

Abstract
The long-acting β2-agonist (LABA) / long-acting muscarinic antagonist (LAMA) fixed dose combination (FDC) therapy represents the cornerstone for the treatment of chronic obstructive pulmonary disease (COPD). Nevertheless, conflicting clinical findings still exist on the real benefit of the LABA/LAMA FDCs. Therefore, we investigated whether combining the LABA vilanterol with the LAMA umeclidinium may induce synergistic bronchorelaxant effect in isolated airways. The effect of umeclidinium and vilanterol, administered alone, in combination at the ratio of concentrations reproducing the doses delivered by Anoro® Ellipta® (55:22), or at isoeffective low concentrations, was investigated on the cholinergic contractile tone induced by the parasympathetic activation of human isolated airways. The interaction was analyzed by using the Bliss Independence and Unified Theory models. Umeclidinium and vilanterol induced a concentration-dependent relaxation of isolated bronchi, with umeclidinium significantly (P < 0.05) more potent than vilanterol (Emax at 10Hz: umeclidium 102.6 ± 6.8%, vilanterol 75.1 ± 13.8%; pEC50 at 10Hz: umeclidinium 8.6 ± 0.4, vilanterol 6.9 ± 0.6). When administered at 55:22 concentration-ratio, umeclidinium plus vilanterol completely relaxed the isolated airways (Emax at 10Hz: 99.6 ± 8.0%; pEC50 at 10Hz: 8.2 ± 0.4). No synergistic interaction was detected for umeclidinium/vilanterol combined at 55:22 ratio, whereas strong synergism was elicited when the drugs were administered at low isoeffective concentrations (+ 41.4 ± 5.8% vs. monocomponents), leading to submaximal relaxant effect (81.4 ± 5.8%). Umeclidinium and vilanterol are imbalanced when combined at 55:22 ratio, with umeclidinium over-dosed, or vice versa vilanterol under-dosed. Specific studies are needed to identify the dose ratio of umeclidinium/vilanterol combination to guarantee equipotency concentrations of each component into the lung, and induce synergistic bronchodilation.

Abstract
Background Intracellular mechanisms of action of umeclidinium (UMEC), a long-acting muscarinic receptor antagonist, and vilanterol (VI), a long-acting β2-adrenoceptor (β2R) agonist, were investigated in target cells: human airway smooth-muscle cells (ASMCs). Materials and methods ASMCs from tracheas of healthy lung-transplant donors were treated with VI, UMEC, UMEC and VI combined, or control compounds (salmeterol, propranolol, ICI 118.551, or methacholine [MCh]). Cyclic adenosine monophosphate (cAMP) was measured using an enzyme-linked immunosorbent assay, intracellular free calcium ([Ca2+]i) using a fluorescence assay, and regulator of G-protein signaling 2 (RGS2) messenger RNA using real-time quantitative polymerase chain reaction. Results VI and salmeterol (10−12–10−6 M) induced cAMP production from ASMCs in a concentration-dependent manner, which was greater for VI at all concentrations. β2R antagonism by propranolol or ICI 118.551 (10−12–10−4 M) resulted in concentration-dependent inhibition of VI-induced cAMP production, and ICI 118.551 was more potent. MCh (5×10−6 M, 30 minutes) attenuated VI-induced cAMP production (P<0.05), whereas pretreatment with UMEC (10−8 M, 1 hour) restored the magnitude of VI-induced cAMP production. ASMC stimulation with MCh (10−11–5×10−6 M) resulted in a concentration-dependent increase in [Ca2+]i, which was attenuated with UMEC pretreatment. Reduction of MCh-induced [Ca2+]i release was greater with UMEC + VI versus UMEC. UMEC enhanced VI-induced RGS2 messenger RNA expression. Conclusion These data indicate that UMEC reverses cholinergic inhibition of VI-induced cAMP production, and is a more potent muscarinic receptor antagonist when in combination with VI versus either alone.

Abstract
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity, mortality and health care expenditure throughout the world. COPD guidelines recommend the use of long-acting muscarinic antagonist (LAMA) either alone or in combination with a long-acting β2 agonist (LABA). For over 10 years, tiotropium was the only LAMA that was used in the management of COPD. Over the past few years, various new drugs have been identified that act on the muscarinic receptors and β2 receptors. Umeclidinium (Umec) is a new LAMA currently approved for use in patients with COPD either as monotherapy or in combination with vilanterol (Vil). Both Umec alone and in combination with Vil delivered through a multi-dose dry powder Ellipta™ device have shown improvement in lung function, health-related quality of life and exacerbation frequency in patients with COPD. This review provides an overview of the pharmacology, pharmacodynamics and pharmacokinetics of Umec, and evaluates the clinical efficacy and safety studies in patients with COPD.

Abstract
INTRODUCTION Long-acting bronchodilators are pivotal in the therapeutic management of COPD patients with moderate-to-severe airflow obstruction. New ultra-long-acting β2-agnoists (ultra-LABAs) have been developed, some of which have been licensed for use as monotherapy and/or in combination with other bronchodilators or inhaled corticosteroids, for use in COPD patients with persistent symptoms and worsening airflow limitation. These new agents are faster in onset and have a prolonged duration of action, with a similar safety profile to the traditional twice-daily bronchodilators which may have an impact on patient concordance. Areas covered: A number of these ultra-LABAs are still under development and bi-functional hybrid molecules containing regions functioning as β2-agonists, and as muscarinic agonists (MABAs) has been developed. This review summarizes these (excluding the licensed ultra-LABAs) with attention on phase II studies data available to-date on their pharmacological profiles, clinical efficacy and safety, and future perspectives. Expert opinion: Despite all the new agents' available, the challenges that persist include any differences in efficacy and safety between the various possible LAMA/LABA combinations, relative advantages of MABAs over fixed-dose LAMA/LABAs, and the impact of these new molecules in terms of long term safety, especially in certain populations in co-morbidities frequently associated with COPD.
