Pharmaceuticals (Basel) 2023; 16:1609. [PMID: 38004474 PMCID: PMC10675027 DOI: 10.3390/ph16111609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 11/06/2023] [Accepted: 11/11/2023] [Indexed: 11/26/2023] Open
Abstract
INTRODUCTION Adding LAMA to LABA/ICS is recommended to improve control in patients with persistent asthma. METHODS This observational, retrospective, before-and-after study considered patients diagnosed with asthma who started LABA/ICS + LAMA treatment (triple therapy, TT) between 1 January 2017 and 31 December 2018 and had been treated with LABA/ICS (dual therapy, DT) in the year before. Changes in lung function and exacerbation rates, healthcare resource utilization, and healthcare and non-healthcare costs (€2019) were estimated in patients with asthma in clinical practices in Spain. Data from computerized medical records from seven Spanish regions were collected ±1 year of LAMA addition. RESULTS 4740 patients (64.1 years old [SD: 16.3]) were included. TT reduced the incidence of exacerbations by 16.7% (p < 0.044) and the number of patients with exacerbations by 8.5% (p < 0.001) compared to previous DT. The rate of patients with severe exacerbations requiring systemic corticosteroids and their hospitalization rates significantly decreased by 22.5% and 29.5%. TT significantly improved FEV1, FVC, and FEV1/FVC, saving €571/patient for society. Younger patients with asthma (18-44 years old) and patients with severe asthma (FEV1 < 60%) performed better upon the initiation of TT. CONCLUSIONS TT reduced asthma exacerbations, improved lung function and reduced healthcare costs vs. DT, particularly in patients requiring systemic corticosteroids to treat severe exacerbations.

Efficacy of mometasone/indacaterol/glycopyrronium in patients with inadequately controlled asthma with respect to baseline eosinophil count: Post hoc analysis of IRIDIUM study. Respir Med 2023; 217:107334. [PMID: 37392789 DOI: 10.1016/j.rmed.2023.107334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 06/09/2023] [Accepted: 06/16/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND Baseline characteristics could potentially guide asthma treatments. We evaluated whether baseline eosinophil levels affect the efficacy of mometasone/indacaterol/glycopyrronium (MF/IND/GLY) in patients with inadequately controlled asthma. METHOD In this post hoc analysis of IRIDIUM study, efficacy of high-dose MF/IND/GLY (160/150/50 μg, once-daily [o.d.]) versus high-dose MF/IND (320/150 μg o.d.) and high-dose fluticasone/salmeterol (FLU/SAL [500/50 μg, twice-daily [b.i.d.]); and efficacy of pooled MF/IND/GLY (160/150/50 μg and 80/150/50 μg) versus pooled MF/IND (320/150 μg and 160/150 μg) was evaluated in patient subgroups with baseline blood eosinophil count of <300 cells/μL or ≥300 cells/μL. RESULTS Overall, 3065 patients were included. At Week 26, high-dose MF/IND/GLY showed improved trough FEV1 versus high-dose MF/IND (Δ78mL [<300 cells/μL]; Δ54mL [≥300 cells/μL]) and FLU/SAL (Δ112mL [<300 cells/μL]; Δ98mL [≥300 cells/μL]). Similarly, pooled MF/IND/GLY also showed improved trough FEV1 versus pooled MF/IND (Δ75mL [<300 cells/μL]; Δ68mL [≥300 cells/μL]). Over 52 weeks, high-dose MF/IND/GLY reduced the annualized rate of moderate or severe asthma exacerbations by 23% and 10%, severe exacerbations by 31% and 15%, and all exacerbation by 33% and 10% versus high-dose MF/IND for subgroups with <300 cells/μL and ≥300 cells/μL, respectively; and by 33% and 41%, 45% and 42%, 42% and 39% versus FLU/SAL, respectively. Similarly, pooled MF/IND/GLY reduced exacerbations by 22% and 8%, 21% and 7%, 27% and 8%, versus pooled MF/IND, for the respective subgroups. CONCLUSION MF/IND/GLY showed improvement in lung function and reduction in asthma exacerbations over MF/IND and FLU/SAL independent of baseline eosinophil levels, indicating that eosinophil levels did not affect the efficacy of MF/IND/GLY in patients with inadequately controlled asthma.

Abstract
The journey of using anticholinergics in the treatment of asthma started with anticholinergic-containing plants such as Datura stramonium and Atropa belladonna, followed by ipratropium bromide and continued with tiotropium, glycopyrronium, and umeclidinium. Although antimuscarinics were used in the maintenance treatment of asthma over a century ago, after a long time (since 2014), it has been recommended to be used as an add-on long-acting antimuscarinic agent (LAMA) therapy in the maintenance treatment of asthma. The airway tone controlled by the vagus nerve is increased in asthma. Allergens, toxins, or viruses cause airway inflammation and inflammation-related epithelial damage, increased sensory nerve stimulation, ganglionic and postganglionic acetylcholine (ACh) release by inflammatory mediators, intensification of ACh signaling at M1 and M3 muscarinic ACh receptors (mAChRs), and dysfunction of M2 mAChR. Optimal anticholinergic drug for asthma should effectively block M3 and M1 receptors, but have minimal effect on M2 receptors. Tiotropium, umeclidinium, and glycopyrronium are anticholinergic agents with this feature. Tiotropium has been used in a separate inhaler as an add-on treatment to inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA), and glycopyrronium and umeclidinium have been used in a single inhaler as a combination of ICS/LABA/LAMA in asthma in recent years. Guidelines recommend this regimen as an optimization step for patients with severe asthma before initiating any biologic or systemic corticosteroid therapy. In this review, the history of antimuscarinic agents, their effectiveness and safety in line with randomized controlled trials, and real-life studies in asthma treatment will be discussed according to the current data.

Abstract
PURPOSE Recently, single-inhaler triple therapy (SITT) has demonstrated efficacy in patients with uncontrolled asthma who were symptomatic despite treatment with inhaled corticosteroids/long-acting β2 agonists. However, the characteristics of patients who benefit from SITT remain unclear in the real-world. The aim of this study was to examine the predictors of responsiveness to SITT in patients with asthma. PATIENTS AND METHODS A total of 45 patients with asthma who had regularly visited our respiratory clinic and were started on SITT from March 2019 to March 2021 were retrospectively analyzed. Patients' demographic characteristics, residual respiratory symptoms, type 2 biomarkers, and lung function before SITT were assessed from the patients' medical records. Predictors of responsiveness to four-week SITT were evaluated in these patients. The definition of responders was based on the physician-assessed global evaluation of treatment effectiveness. RESULTS Thirty-four (75%) of 45 patients were identified as responders to SITT. Non-responders showed significantly lower forced vital capacity (FVC) (%predicted) values, and complained of dyspnea more frequently than responders before SITT (p = 0.01 and p = 0.02, respectively). There were no significant differences in demographic characteristics and type 2 biomarkers between responders and non-responders. Clinical predictors of poor response to SITT were residual dyspnea (OR = 0.14, p = 0.02), low FVC (%predicted) values (OR = 1.05, p = 0.01), and FVC (%predicted) <80% (OR = 0.11, p = 0.02). Multivariate analysis showed that poor response to SITT was associated with residual dyspnea before SITT (OR = 0.14, p = 0.02). On the other hand, patients with residual dyspnea had significantly lower FEF25-75 (%predicted) values than patients without residual dyspnea before SITT (p = 0.04). CONCLUSION Residual dyspnea, reflecting small airways dysfunction, may predict poor responsiveness to short-term SITT in patients with asthma.

Abstract
INTRODUCTION Childhood asthma is a complex heterogenous inflammatory disease that can pose a large burden on patients and their caregivers. There is a strong need to adapt asthma treatment to the individual patient taking into account underlying inflammatory profiles, moving from a 'one size fits all' approach toward a much-needed personalized approach. AREAS COVERED This review article aims to provide an overview of recent advances in the management and treatment of pediatric asthma, including novel insights on the molecular heterogeneity of childhood asthma, the emergence of biologicals to treat severe asthma, and innovative e-health and home monitoring techniques to make asthma management more convenient and accessible. EXPERT OPINION Molecular technologies have provided new treatment leads. E-health and home monitoring technologies have helped to gain more insights into disease dynamics and improve adherence to treatment while bringing health care to the patient. However, uncontrolled childhood asthma is still a major unmet clinical need and precision-medicine approaches are still scarce in clinical practice. Advanced omics methods may help researchers or clinicians to more accurately phenotype and treat subtypes of childhood asthma and gain more insight into the complexity of the disease.

Abstract
INTRODUCTION Since long-acting muscarinic antagonists (LAMA) are only indicated as add-on therapy in subjects with moderate-to-severe asthma, there are concerns whether LAMA monotherapy is associated with worse asthma control. AIM To study the prevalence of LAMA monotherapy and its potential association with severe asthma exacerbations (SAE) in patients with asthma. METHODS A cohort study (2007-2017) in the IPCI primary care database, in asthma patients aged 6-50, using LAMA during follow-up. Respiratory prescriptions were retrieved from the electronic medical records based on ATC code. Asthma treatment periods were created and categorized as LAMA mono, dual (LAMA + ICS), or triple therapy (LAMA + ICS + LABA). Relative rates (RR) of SAE, adjusting for patient characteristics, were estimated to compare treatments. RESULTS From a total of 66,508 asthma patients, 1236 (1.9%) LAMA users were identified. Median age was 41 years, 65.9% were females. LAMA users were responsible for 3596 LAMA treatment periods of which 1390 (38.7%) were LAMA monotherapy, 553 (15.4%) dual therapy and 1653 (46.0%) triple therapy. The RR of SAE during LAMA monotherapy compared to dual therapy was 1.5 (95% CI 0.6-3.8). In patients alternating between mono and dual therapy (but never triple therapy), the RR for LAMA monotherapy increased to 5.7 (95% CI 1.4-23.6). CONCLUSIONS This observational study shows that when LAMA is prescribed, it is often prescribed without concurrent ICS (LAMA monotherapy). LAMA monotherapy was associated with an increased risk of exacerbations when not used concurrently with ICS. This emphasizes the importance that LAMA should never be prescribed without concomitant ICS use in patients with asthma.

Abstract
Background A number of single-inhaler triple therapies are being developed for asthma, including the extrafine formulation of beclometasone dipropionate (BDP), formoterol fumarate (FF), and glycopyrronium (G). Given asthma is a heterogenous disease, we investigated whether the clinical response to the addition of the long-acting muscarinic antagonist component within inhaled triple therapy was impacted by a range of clinical characteristics. Methods These were pre-specified and post-hoc sub-group analyses of TRIMARAN and TRIGGER, which were double-blind, 52-week studies comparing medium-strength (100/6/10 µg; TRIMARAN) and high-strength (200/6/10 µg; TRIGGER) BDP/FF/G with the respective BDP/FF strengths in adults with uncontrolled asthma and a history of ≥ 1 exacerbation. Co-primary endpoints were pre-dose forced expiratory volume in 1 s (FEV1) at Week 26 and the rate of moderate-to-severe exacerbations over 52 weeks. Key secondary endpoints: peak FEV1 at Week 26 and average morning peak expiratory flow over the first 26 weeks in each study, and severe exacerbation rate over 52 weeks (pooled data). Results Baseline clinical characteristics (pre-specified analyses) had no consistent effect on the lung function improvements with BDP/FF/G. For the exacerbation endpoints, sub-groups with higher reversibility gained greatest relative benefit from BDP/FF/G versus BDP/FF. In post-hoc analyses with patients sub-grouped by screening blood eosinophil values, in TRIMARAN the greatest relative effect of BDP/FF/G versus BDP/FF on the lung function endpoints was in the ≤ 300 cells/µL group; in TRIGGER, eosinophil levels did not markedly influence the relative efficacy of BDP/FF/G versus BDP/FF. Eosinophil levels did not influence relative efficacy on moderate-to-severe or severe exacerbations. Conclusion Overall, the relative efficacy of extrafine BDP/FF/G versus BDP/FF was not influenced by a range of clinical characteristics. However, some patient sub-groups gained additional benefit from BDP/FF/G for certain endpoints. In particular, for exacerbations the relative efficacy of BDP/FF/G was greater in more reversible patients. Trial registration ClinicalTrials.gov: TRIMARAN, NCT02676076 (registered February 8, 2016, https://clinicaltrials.gov/ct2/show/NCT02676076?term=NCT02676076&draw=2&rank=1,); TRIGGER, NCT02676089 (registered February 8, 2016, https://clinicaltrials.gov/ct2/show/NCT02676089?term=NCT02676089&draw=2&rank=1)

Abstract
Bronchodilators remain the cornerstone of the treatment of airway disorders such as asthma and chronic obstructive pulmonary disease (COPD). There is therefore considerable interest in understanding how to optimize the use of our existing classes of bronchodilator and in identifying novel classes of bronchodilator drugs. However, new classes of bronchodilator have proved challenging to develop because many of these have no better efficacy than existing classes of bronchodilator and often have unacceptable safety profiles. Recent research has shown that optimization of bronchodilation occurs when both arms of the autonomic nervous system are affected through antagonism of muscarinic receptors to reduce the influence of parasympathetic innervation of the lung and through stimulation of β 2-adrenoceptors (β 2-ARs) on airway smooth muscle with β 2-AR-selective agonists to mimic the sympathetic influence on the lung. This is currently achieved by use of fixed-dose combinations of inhaled long-acting β 2-adrenoceptor agonists (LABAs) and long-acting muscarinic acetylcholine receptor antagonists (LAMAs). Due to the distinct mechanisms of action of LAMAs and LABAs, the additive/synergistic effects of using these drug classes together has been extensively investigated. More recently, so-called "triple inhalers" containing fixed-dose combinations of both classes of bronchodilator (dual bronchodilation) and an inhaled corticosteroid in the same inhaler have been developed. Furthermore, a number of so-called "bifunctional drugs" having two different primary pharmacological actions in the same molecule are under development. This review discusses recent advancements in knowledge on bronchodilators and bifunctional drugs for the treatment of asthma and COPD. SIGNIFICANCE STATEMENT: Since our last review in 2012, there has been considerable research to identify novel classes of bronchodilator drugs, to further understand how to optimize the use of the existing classes of bronchodilator, and to better understand the role of bifunctional drugs in the treatment of asthma and chronic obstructive pulmonary disease.

Abstract
Asthma imposes a significant burden on the health system and patients' quality of life. Within Asia, there is large variability in several cultural, social and economic factors ultimately influencing the management of asthma. Differences in risk factors and asthma management practices across Asia make asthma a truly 'mixed-bag' phenomenon. With the advent of biological agents and the consequent emphasis on asthma phenotyping and endotyping, it is more important than ever to understand the diverse nature of asthma as a disease. This is a collaborative review within Asia to highlight the differences in management of adult asthma, and the local modifications that are made to international guidelines. This review paves the way for a future Asian collaborative network in asthma epidemiological research.

Abstract
INTRODUCTION There is increasing evidence that tiotropium, a long-acting muscarinic agent (LAMA), is useful in the presence of severe-uncontrolled asthma despite the optimization of therapy with inhaled corticosteroids (ICSs) and long-acting β2 agonists (LABAs) as recommended by the current guidelines. Furthermore, in recent years there have been several preclinical and clinical studies on the pharmacological and therapeutic impact of other LAMAs in asthma. AREAS COVERED We have conducted an extensive search on muscarinic antagonists in asthma therapy throughout several sources and discuss what has emerged in the last 3 years (January 2017-March 2020). EXPERT OPINION New evidence indicates that the effectiveness of adding a LAMA, at least tiotropium, is independent of the degree of the type 2 inflammation and age of patient. Therefore, tiotropium can be administered without the need for patient phenotyping. Umeclidinium and glycopyrronium also appear effective in asthma. Initial treatment with LAMA+ICS for those with mild asthma may be an equally effective therapeutic option as LABA+ICS but this hypothesis should be confirmed by statistically powered trials.

Abstract
Background Asthma-COPD overlap (ACO; previously referred to as asthma-COPD overlap syndrome) is characterized by persistent airflow limitation consistent with COPD, together with several distinguishing features of asthma. Asthma-COPD overlap syndrome is a condition of mixing symptoms of asthma and COPD, because of its complexity, it is difficult to find effective diagnostic markers in clinic. Purpose Our aims were to detect the expression of serum cytokines in patients with asthma, explore the diagnostic potential of differential serum cytokines in ACOS. Patients and Methods Ninety asthmatic patients were divided into ACOS group and non-ACOS group according to the major and minor criteria of ACOS, 15 kinds of cytokines including IL-3, IL-4, IL-8, IL-9, IL-13, IL-17A, VEGFA, VEGFC, VEGFD, bFGF, Fit-1 PIGF, Tie-2 were detected by MSD, and IL-27 and TGF-beta were determined by ELISA assay. Results The serum levels of IL-9, VEGFA and PIGF in patients with ACOS were significantly higher than those in non-ACOS group (P<0.05, respectively), while the level of IL-8 and IL-17A in subjects with ACOS was lower than that in the non-ACOS group (P<0.05, respectively). We analyzed the correlation between several difference factors and FEV1/FVC% in the ACOS group, found VEGFA was negatively correlated with FEV1/FVC%, while IL-8 and IL-17A were positively correlated with FEV1/FVC%. Finally, three correlation factors were analyzed by ROC curve for the occurrence of ACOS. Conclusion The results suggested that IL-8 was highly sensitive and VEGFA was highly specificity, both of which could be used as biomarkers for the diagnosis of ACOS.

Abstract
Background According to several phase III studies, tiotropium [a long-acting muscarinic antagonist (LAMA)] is a well-tolerated add-on therapy to inhaled corticosteroids (ICS) for asthmatics with or without the addition of long-acting beta2-agonists (LABAs). However, real-world studies based on clinical phenotypes to predict the long-term need of tiotropium as an add-on therapy for asthmatics are limited. Methods This is a retrospective study conducted at a single medical center in Taiwan from July 2016 to July 2018. An asthma control test (ACT) is applied to uncontrolled asthmatics to evaluate the effectiveness of tiotropium as an add-on therapy. Asthmatic subgroups with different clinical phenotypes and needing long-term tiotropium as a maintenance treatment are identified. The effectiveness of tiotropium add-on therapy is defined as an improvement of ACT score ≥3 points 3 months after the treatment (vs. baseline), while the long-term requirement of tiotropium is defined as tiotropium dependency >1 year. Results The study analyzed a total of 160 uncontrolled asthmatics regardless of low- or medium-to-high-dose ICS plus LABA. One hundred and twelve patients responded well (ACT score increased ≥3 points) to tiotropium. These patients were further divided into two subgroups: one with tiotropium add-on therapy for ≥1 year due to patients' difficulties in stepping down from tiotropium; the other with tiotropium add-on therapy for <1 year due to successful step-down treatment according to Global Initiative for Asthma (GINA) score. All clinical characteristics of these two groups were collected and analyzed. Univariate and multivariate analyses showed that asthma-and-chronic obstructive pulmonary disease (COPD)-overlap (ACO), initial forced expiratory volume-one second (FEV1) % predicted <80%, or body mass index (BMI) >30 kg/m2 were predictors for asthmatics requiring long-term tiotropium add-on therapy. Conclusions Tiotropium add-on therapy is effective for uncontrolled asthmatics. Moreover, patients with ACO, initial FEV1% predicted <80%, or BMI >30 kg/m2 require long-term tiotropium add-on therapy for asthma control.
