Krings JG, Beasley R. The Role of ICS-Containing Rescue Therapy Versus SABA Alone in Asthma Management Today. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2024; 12:870-879. [PMID: 38237858 PMCID: PMC10999356 DOI: 10.1016/j.jaip.2024.01.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/14/2023] [Accepted: 01/01/2024] [Indexed: 02/05/2024]
Abstract
The Global Initiative for Asthma (GINA) recommends that short-acting β2-agonist (SABA) monotherapy should no longer be prescribed, and that as-needed combination inhaled corticosteroids (ICS)-formoterol is the preferred reliever therapy in adults and adolescents with mild asthma. These recommendations are based on the risks of SABA monotherapy, the evidence that ICS-formoterol reliever therapy markedly decreases the occurrence of severe asthma exacerbations compared with SABA reliever therapy alone, and because ICS-formoterol reliever therapy has a favorable risk/benefit profile compared with maintenance ICS plus SABA reliever therapy. Data supporting the use of combination ICS-albuterol reliever therapy in mild asthma are more limited, but there are studies that inform its use in this population. In this review, we compare, using a pros and cons format, the (1) long-term safety and efficacy of ICS-formoterol reliever therapy versus SABA reliever therapy alone, (2) long-term safety and efficacy of ICS-albuterol reliever therapy versus SABA reliever therapy alone, (3) immediate bronchodilator effects of ICS-formoterol versus SABA alone, and (4) clinical and regulatory factors that may inform reliever therapy prescription decisions. By presenting the evidence of these reliever inhaler options, we hope to inform the reader while also calling for necessary future effectiveness and implementation research.

Abstract
The Global Initiative for Asthma recommends that low-dose inhaled corticosteroid (ICS)/formoterol be preferred to short-acting beta2-agonists as reliever therapy in adolescents and adults with asthma, across the range of asthma severity. This recommendation represents the most fundamental change in asthma management for many decades. In this commentary, we review the rationale for combination ICS/formoterol therapy, the evidence on which this recommendation has been made, the limitations in the evidence, the practical issues relevant to the implementation of ICS/formoterol reliever-based regimens in clinical practice, and the emerging evidence for the efficacy and safety of combination ICS/salbutamol reliever therapy regimens.

Vähätalo I, Lehtimäki L, Tuomisto LE, Karjalainen J, Niemelä O, Ilmarinen P, Kankaanranta H. Long-Term Use of Short-Acting β 2-Agonists in Patients With Adult-Onset Asthma. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2074-2083.e7. [PMID: 35398551 DOI: 10.1016/j.jaip.2022.03.027] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 03/15/2022] [Accepted: 03/25/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Short-term studies have associated high use of short-acting β2-agonists (SABA) with increased risk of exacerbations, emergency visits, and asthma-related costs. However, no studies exist on long-term SABA use, and previous studies on the topic have not included information about adherence to inhaled corticosteroids (ICS) nor disease control, both affecting the need of SABA. OBJECTIVE To evaluate the clinical characteristics of SABA and ICS usage in newly diagnosed adult-onset asthma patients during a 12-year follow-up period. METHODS In the Seinäjoki Adult Asthma Study, 203 patients with adult-onset asthma were followed for 12 years. Information on dispensed SABA and ICS during the follow-up was obtained from the Finnish Social Insurance Institution. High SABA use was defined as ≥36 canisters in 12 years, corresponding to an average of ≥3 dispensed canisters/y. RESULTS Patients were dispensed median 6 (interquartile range: 3-16) SABA canisters and 48 (18-67) ICS canisters over 12 years, corresponding to 2 (1-4) and 11 (5-16) puffs/week, respectively. Only 10% of the patients were classified as high SABA users during this period. Obesity (body mass index ≥30) and high Airways Questionnaire 20 symptom scores at baseline predicted high long-term SABA use (incidence rate ratio: 1.53 [1.01-2.30] and 1.04 [1.00-1.08], respectively). High SABA users had higher ICS adherence, higher blood neutrophil counts, more comorbidities, and used more oral corticosteroid and antibiotic courses versus low SABA users. CONCLUSION High SABA use was infrequent in patients with confirmed adult-onset asthma. However, as high SABA use is associated with more severe asthma, these patients should be recognized in clinical practice.

Abstract
Background: The efficacy of budesonide + formoterol therapy compared with high-dose salmeterol + fluticasone therapy plus short-acting β-agonist (SABA) has not been evaluated specifically in children. Objectives: To evaluate the efficacy and safety of budesonide + formoterol combination therapy two times a day plus as needed compared with salmeterol + fluticasone two times a day plus SABA (as needed) in children in China. Methods: This prospective cohort study included 164 children with persistent asthma (aged 12-17 years) who had experienced a minimum of one asthma exacerbation in 12 months prior to the study. The primary outcome was the time to the first severe exacerbation. Results: Eighty-two children were assigned to each of two groups. The exacerbation rate per 100 patients per year was not found to be significantly different. The number of patients with hospitalization/emergency room therapy was lower in budesonide + formoterol group, but the risk difference was not statistically significant. Asthma control measures showed comparable effects. Both treatments were well-tolerated. Conclusion: No significant differences were observed in the outcome measures between the groups. Budesonide + formoterol therapy is a favorable approach in terms of a low load of ICS, steroid exposure, need for multiple inhalers and cost.

Lugogo N, Gilbert I, Tkacz J, Gandhi H, Goshi N, Lanz MJ. Real-world patterns and implications of short-acting β 2-agonist use in patients with asthma in the United States. Ann Allergy Asthma Immunol 2021; 126:681-689.e1. [PMID: 33515710 DOI: 10.1016/j.anai.2021.01.024] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 12/18/2020] [Accepted: 01/19/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Short-acting β2-agonist (SABA) use is one measure reflecting asthma control. OBJECTIVE To evaluate the associations between real-world SABA use and severe asthma exacerbations in the United States. METHODS Patients with asthma 12 years of age or older receiving SABA in the IBM MarketScan research databases of US administrative claims from September 30, 2014, to September 30, 2016, were evaluated. Patients with 12 months' continuous eligibility before and after their first SABA claim (index SABA), an asthma diagnosis before through 60 days postindex, and either one additional SABA or at least 1 maintenance fill(s) were included. SABA claims postindex (including index fill) were grouped as follows: low: index only; medium: 2 to 3 canisters per year; and high: 4 or more canisters per year. Differences in SABA exposure with respect to disease severity groups and severe asthma exacerbations (hospitalizations, emergency visits, or outpatient systemic corticosteroids) were analyzed by analysis of variance and χ2 (significance, P ≤ .05). RESULTS A total of 135,540 patients were included: 62.8% women; mean (SD) age, 40.9 (18.3) years; SABA fills per 12-months postindex: 3.0(2.7). Furthermore, 28% of patients filled 1 SABA, 47% 2 to 3, and 25% 4 or more canisters per year. Despite higher maintenance medication possession ratio with increasing SABA (low, 0.53 (0.37); medium, 0.59 (0.35); high, 0.66 (0.32)), annual exacerbation rate per person per year and percent of patients within each SABA group having at least 1 exacerbation rose as SABA fills increased (low, 1.00 (1.45), 45.8%; medium, 1.20 (1.62), 54.3%; high, 1.50 (1.94), 58.7%). Mean SABA fills differed between patients with 0 exacerbation, 2.8 (2.6); 1 exacerbation, 2.9 (2.5); and 2 or more exacerbations, 3.3 (2.9). CONCLUSION Exacerbation risk increased with increasing SABA fills. Management strategies ensuring adequate anti-inflammatory therapy delivered to the airways when symptoms occur may be needed to mitigate asthma morbidity.

Effects of a novel roflumilast and formoterol fumarate dry powder inhaler formulation in experimental allergic asthma. Int J Pharm 2020; 588:119771. [PMID: 32805379 DOI: 10.1016/j.ijpharm.2020.119771] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 08/10/2020] [Accepted: 08/11/2020] [Indexed: 12/14/2022]
Abstract
In this study we aimed to develop a roflumilast (R) and formoterol fumarate (F) dry powder inhaler formulation (DPI) incorporating HPβCD by spray drying and evaluated if it attenuates the inflammatory process and improves lung function in a murine model of ovalbumin induced allergic asthma. The DPI was characterized by powder X-ray diffraction, thermal analysis, scanning electron microscopy, particle size, density, specific surface area and dynamic vapor sorption analyses. In vitro deposition studies were performed using a NGI, while transepithelial permeability and in vivo effects on lung mechanics and inflammation in a model of allergic asthma were also assessed. The R:F formulation was amorphous with high glass transition temperatures, comprised of wrinkled particles, had low bulk and tapped densities, high surface area, suitable particle size for pulmonary delivery and exhibited no recrystallization even at high relative humidities. MMAD were statistically similar of 4.22 ± 0.19 and 4.32 ± 0.13 µm for F and R, respectively. Fine particle fractions (<5 µm) were of more than 50% of the emitted dose. The R:F formulation led to reduced eosinophil infiltration and airway collagen fiber content, yielding decreased airway hyperresponsiveness. In the current asthma model, the R:F formulation combination decreased inflammation and remodeling, thus improving lung mechanics.

Variability in airway inflammation, symptoms, lung function and reliever use in asthma: anti-inflammatory reliever hypothesis and STIFLE study design. ERJ Open Res 2020; 6:00333-2019.

Abstract
Asthma is a chronic inflammatory airway disease. Increase in airway inflammation is hypothesised to contribute to worsening of asthma symptoms and deterioration in lung function, resulting in the use of reliever medication. Short-acting β2-agonists only treat the symptoms, whereas an anti-inflammatory reliever is believed to treat both symptoms and the underlying inflammation, thereby arresting the progression to an exacerbation. As-needed budesonide/formoterol as an anti-inflammatory reliever reduces the risk of severe exacerbations. However, supporting mechanistic evidence has not yet been described, specifically the temporal dynamics of parameters including airway inflammation, over time and during asthma worsening. The STIFLE study aims to characterise daily variability in airway inflammation, symptoms, lung function and reliever use in people with asthma. This phase IV, open-label, parallel-group, multicentre, exploratory study will enrol 60-80 adult patients with asthma receiving low- or medium-dose inhaled corticosteroids/long-acting β2-agonists (EudraCT identifier number 2018-003467-64). Participants will be randomised 1:1 to either as-needed budesonide/formoterol dry-powder inhaler or salbutamol reliever for 24 weeks, in addition to their maintenance therapy. Daily data will be captured for fractional exhaled nitric oxide, spirometry, asthma symptoms and medication use using devices connected to a smartphone via the STIFLE application. STIFLE will thereby enable not only characterisation of the variability of airway inflammation and clinical outcomes in relation to asthma worsening, but also elucidate the effect of as-needed budesonide/formoterol on airway inflammation against a background of daily maintenance therapy.

Abstract
Despite access to diagnostic tests and effective therapies, asthma often remains misdiagnosed and/or poorly controlled or uncontrolled. In this review, we address the key issues of asthma diagnosis and management, recent evidence for levels of asthma control, the consequences of poor control and, in line with that, explore the potential reasons for poor asthma control and acute exacerbations. Based on recent evidence and current guidelines, we also aim to provide practical answers to the key questions of how to improve asthma management, with the best possible prevention of exacerbations, addressing the basics-adherence, inhaler misuse, obesity and smoking-and how to facilitate a new era of asthma care in the twenty-first century. We hope this review will be useful to busy primary care clinicians in their future interactions with their patients with both suspected and proven asthma.

Abstract
Inhaled corticosteroids (ICS) adherence is important for asthma management. Current evidence on the impact of ICS adherence on outcomes is mostly based on correlational analyses of between-person data. Although it is widely acknowledged that asthma outcomes fluctuate over time, evidence on predictors of within-person change is scarce. We aimed to quantify these fluctuations and the longitudinal relationships between ICS adherence and outcomes at both between- and within-person levels.A prospective cohort of persistent asthma patients in France and the UK (n=847, age 6-40 years) provided 3756 reports over up to 2 years via computer-assisted telephone interviews and text messages on ICS adherence, asthma control, reliever medication use and exacerbations. We examined adherence-outcome relationships via longitudinal models, controlling for confounders, including severity.Considerable within-person variability was found for exacerbations (91%), asthma control (59%) and reliever use (52%); 431 (11.5%) reports signalled exacerbations and 2046 (54.5%) poor control. At between-person level, patients with higher average adherence were more likely to report asthma control (OR 1.25, 95% CI 1.06-1.47), but not asthma exacerbations (OR 0.99, 95% CI 0.87-1.12) or lower reliever use (b -0.0004, 95% CI -0.089-0.088). At within-person level, higher-than-usual adherence was associated with higher concomitant reliever use (b 0.092, 95% CI 0.053-0.131) and lower subsequent reliever use (b -0.047, 95% CI -0.005- -0.088); it was unrelated to asthma control (OR 0.93, 95% CI 0.84-1.02) or exacerbations (OR 1.04, 95% CI 0.94-1.16).Patients maintaining high ICS adherence over time have better asthma control. Temporarily increasing ICS adherence tends to be simultaneous to higher reliever use and reduces reliever use later on. Causes of within-person variation in outcomes require more investigation.

Abstract
Introduction: In recognition of the value of long-term real-world data, a postauthorization
safety study of the inhaled corticosteroid (ICS) fluticasone propionate and
long-acting β2-agonist (LABA) formoterol fumarate
(fluticasone/formoterol; Flutiform®) was conducted. Methods: This was a 12-month observational study of outpatients with asthma aged ⩾ 12
years in eight European countries. Patients were prescribed
fluticasone/formoterol according to the licensed indication, and
independently of their subsequent enrolment in the study. They were then
treated according to local standard practice. The study objectives were to
evaluate the safety and effectiveness of fluticasone/formoterol under
real-world conditions. Results: The safety population for this study comprised 2539 patients (mean age 47.7
years; 94.3% aged ⩾ 18 years; 63.4% female). Most patients (1538/2539,
60.6%) had switched to fluticasone/formoterol from another ICS/LABA,
primarily due to lack of efficacy (1150/2539, 45.3%). Three quarters (77.4%)
of patients were treated for 12 months, and 80.6% continued
fluticasone/formoterol treatment after the study. Adverse events (AEs)
occurred in 60.0% patients, and 10.2% had AEs considered possibly related to
fluticasone/formoterol [most commonly asthma exacerbation (2.0% patients),
dysphonia (1.8%) and cough (1.1%)]. Thirty-six severe AEs, but no serious
AEs, were considered possibly related to fluticasone/formoterol. The
proportion of patients with controlled asthma (based on Asthma Control Test
score ⩾ 20) increased from 29.4% at baseline to 67.4% at study end (last
observation carried forward). The proportion of patients experiencing at
least one severe exacerbation decreased from 35.8% in the year prior to
enrolment to 9.8% during the study. Improvements from baseline to study end
were also observed in Asthma Quality of Life scores and physician/patient
reports of satisfaction with treatment. Conclusion: In this real-world postauthorization safety study, fluticasone/formoterol
demonstrated a safety profile consistent with that seen in controlled
clinical trials, with effectiveness in improving asthma control.

Abstract
The repurposing of drug delivery by the pulmonary route has been applied to treatment and prophylaxis of an increasingly wide range of respiratory diseases. Repurposing has been most successful for the delivery of inhaled bronchodilators and corticosteroids in patients with asthma and chronic obstructive pulmonary disease (COPD). Repurposing utilizes the advantages that the pulmonary route offers in terms of more targeted delivery to the site of action, the use of smaller doses, and a lower incidence of side-effects. Success has been more variable for other drugs and treatment indications. Pulmonary delivery is now well established for delivery of inhaled antibiotics in cystic fibrosis (CF), and in the treatment of pulmonary arterial hypertension (PAH). Other inhaled treatments such as those for idiopathic pulmonary fibrosis (IPF), lung transplant rejection or tuberculosis may also become routine. Repurposing has progressed in parallel with the development of new drugs, inhaler devices and formulations.

Abstract
Pulmonary drug delivery is relatively complex because the respiratory tract has evolved defense mechanisms to keep inhaled drug particles out of the lungs and to remove or inactivate them once deposited. In addition to these mechanical, chemical and immunological barriers, pulmonary drug delivery is adversely affected by the behavioral barriers of poor adherence and poor inhaler technique. Strategies to mitigate the effects of these barriers include use of inhaler devices and formulations that deliver drug to the lungs efficiently, appropriate inhaler technique and improved education of patients. Owing to the advantages offered by the pulmonary route, the challenges that the route poses are worth addressing, and if successfully addressed, the pulmonary route offers huge opportunities, often fulfilling unmet clinical needs.

Respir Res 2018; 19:65. [PMID: 29650006 PMCID: PMC5897944 DOI: 10.1186/s12931-018-0770-7] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Accepted: 04/02/2018] [Indexed: 12/15/2022] Open
Abstract
Background Corticosteroids increase the expression of β2-adrenoceptors (β2-ARs) and protect them against down-regulation. Conversely, β2-AR agonists improve the anti-inflammatory action of corticosteroids. Nevertheless, it is still uncertain whether adding a long-acting β2-AR agonist (LABA) to an inhaled corticosteroid (ICS) results in an additive effect, or there is true synergy. Therefore, the aim of this study was to pharmacologically characterize the interaction between the ICS beclomethasone diproprionate (BDP) and the LABA formoterol fumarate (FF) in a validated human ex vivo model of bronchial asthma. Methods Human medium and small airways were stimulated by histamine and treated with different concentrations of BDP and FF, administered alone and in combination at concentration-ratio reproducing ex vivo that of the currently available fixed-dose combination (FDC; BDP/FF 100:6 combination-ratio). Experiments were performed in non-sensitized (NS) and passively sensitized (PS) airways. The pharmacological interaction was assessed by using Bliss Independence and Unified Theory equations. Results BDP/FF synergistically increased the overall bronchorelaxation in NS and PS airways (+ 15.15% ± 4.02%; P < 0.05 vs. additive effect). At low-to-medium concentrations the synergistic interaction was greater in PS than in NS bronchioles (+ 16.68% ± 3.02% and + 7.27% ± 3.05%, respectively). In PS small airways a very strong synergistic interaction (Combination Index: 0.08; + 20.04% ± 2.18% vs. additive effect) was detected for the total concentrations of BDP/FF combination corresponding to 10.6 ng/ml. Conclusion BDP/FF combination synergistically relaxed human bronchi; the extent of such an interaction was very strong at low-to-medium concentrations in PS small airways.

Abstract
INTRODUCTION The Global Initiative for Asthma (GINA) annual report summarizes the latest evidence for asthma management. GINA recommends stepwise pharmacological treatment, advocating inhaled corticosteroids (ICS) plus rapid, long-acting β2-agonists (LABA) delivered in a single inhaler for maintenance and relief at Steps 3 (moderate persistent asthma requiring 1-2 controllers plus as-needed reliever), 4 (severe persistent asthma requiring ≥2 controllers plus as-needed reliever), and 5 (higher level care and/or add-on treatment). Areas covered: Randomized controlled trials and real-world evidence demonstrate that flexibly dosed budesonide/formoterol for maintenance and relief (Symbicort® Maintenance And Reliever Therapy [SMART]) is associated with reductions in severe exacerbations, prolongs time to first exacerbation, and provides fast symptom relief. Expert commentary: SMART provides greater or equal levels of sustained asthma control than similar or higher fixed doses of ICS/LABA plus short-acting β2-agonist (SABA) as needed or higher ICS plus SABA as needed, with lower overall ICS doses and cost. The simplified dosing strategy may improve adherence and overall asthma control but relies on patient education. Budesonide/formoterol as needed in mild asthma (patients qualifying for regular low-dose ICS) is currently under investigation in two double-blind randomized studies, SYGMA1/2 (NCT02149199/NCT02224157), comparing budesonide/formoterol as needed with budesonide plus SABA and SABA alone.

Abstract
The aim of this study was to examine the daily practice patterns of Symbicort® Maintenance and Reliever Therapy (SMART) in Korean asthmatic patients and to analyze clinical signs related to overuse. This study used an observational, multicenter, noninterventional, prospective, uncontrolled design for examining asthmatic patients prescribed SMART to assess the frequency and pattern of Symbicort® usage as a maintenance and reliever medication. The characteristics of patients showing signs of overuse (frequency of inhalation: 8 or more times per day) were also analyzed. Among the 1,518 patients analyzed, 1,292 (85.1%) completed the trial. The number of mean inhalations per day was 2.14±1.15; the number of patients who had at least 1 as needed usage (PRN) inhalation per day was 843 (55.5%); the mean frequency of PRN use was 0.25±0.67 inhalations per day. The number of patients who overused for at least 1 day was 260 (17.1%). In particular, young patients, patients with limited physical activity, and patients with nocturnal symptoms demonstrated high frequency of overuse. The frequency of overuse during SMART was not high in Korean asthmatic patients and the asthma status of follow-up outpatients improved overall. However, there is a need for careful education targeted toward younger patients, patients with limited physical activity, and patients with nocturnal symptoms owing to their tendency to frequently overuse.

Abstract
Glucocorticosteroids are the most effective anti-inflammatory therapy for asthma but are relatively ineffective in COPD. Glucocorticoids are broad-spectrum anti-inflammatory drugs that suppress inflammation via several molecular mechanisms. Glucocorticoids suppress the multiple inflammatory genes that are activated in asthma by reversing histone acetylation of activated inflammatory genes through binding of ligand-bound glucocorticoid receptors (GR) to coactivator molecules and recruitment of histone deacetylase-2 (HDAC2) to the activated inflammatory gene transcription complex (trans-repression). At higher concentrations of glucocorticoids GR homodimers interact with DNA recognition sites to activate transcription through increased histone acetylation of anti-inflammatory genes and transcription of several genes linked to glucocorticoid side effects (trans-activation). Glucocorticoids also have post-transcriptional effects and decrease stability of some proinflammatory mRNAs. Decreased glucocorticoid responsiveness is found in patients with severe asthma and asthmatics who smoke, as well as in all patients with COPD. Several molecular mechanisms of glucocorticoid resistance have now been identified which involve phosphorylation and other post-translational modifications of GR. HDAC2 is markedly reduced in activity and expression as a result of oxidative/nitrative stress and pi3 kinase-δ inhibition, so that inflammation is resistant to the anti-inflammatory actions of glucocorticoids. Dissociated glucocorticoids and selective GR modulators which show improved trans-repression over trans-activation effects have been developed to reduce side effects, but so far it has been difficult to dissociate anti-inflammatory effects from adverse effects. In patients with glucocorticoid resistance alternative anti-inflammatory treatments are being investigated as well as drugs that may reverse the molecular mechanisms of glucocorticoid resistance.

Abstract
Introduction In adult asthma, combination inhaled corticosteroid (ICS)/fast-onset long-acting beta agonist (LABA) used solely as reliever therapy may represent an effective and safe alternative to ICS maintenance and short-acting beta agonist (SABA) reliever therapy. Objective To compare the efficacy and safety of ICS/fast-onset LABA reliever therapy with ICS maintenance and SABA reliever therapy in adults with asthma. Methods and analysis A 52-week, open-label, parallel group, multicentre, phase III randomised controlled trial with 1:1 randomisation to either budesonide/formoterol Turbuhaler 200/6 µg, one actuation as required for symptom relief, or budesonide Turbuhaler 200 µg, one actuation twice daily and terbutaline Turbuhaler 250 µg, two actuations as required for symptom relief. 890 adults aged 18–75 years with asthma for whom maintenance ICS and SABA reliever therapy is indicated by current guidelines will be recruited in New Zealand. The primary outcome variable is the rate of severe exacerbations per patient per year. This study will investigate a novel treatment regimen that might lead to a paradigm shift in asthma management for adults for whom guidelines currently recommend maintenance ICS and SABA reliever therapy. Ethics and dissemination Ethical approval has been granted (15/NTB/178). Study findings will be published according to Iinternational Committee of Medical Journal Editors' recommendations.

Abstract
Objective: To evaluate the effectiveness of combined epinephrine and corticosteroid therapy for acute bronchiolitis in infants. Methods: Four electronic databases (MEDLINE, EMBASE, CINAHL, and CENTRAL) were searched from their inception to February 28, 2017 for studies involving infants aged less than 24 months with bronchiolitis which assessed the use of epinephrine and corticosteroid combination therapy. The methodological quality of the included studies was assessed using the Cochrane Collaboration's Risk of Bias Tool. A random-effects meta-analysis was used to pool the effect estimates. The primary outcomes were hospital admission rate and length of hospital stay. Results: Of 1,489 citations identified, 5 randomized controlled trials involving 1,157 patients were included. All studies were of high quality and low risk of bias. Results of the meta-analysis showed no significant differences in the primary outcomes. Hospitalization rate was reduced by combinatorial therapy of epinephrine and corticosteroid in only one out of five studies, whereas pooled data indicated no benefit over epinephrine plus placebo. Clinical severity scores were significantly improved in all five RCTs when assessed individually, but no benefit was observed compared to epinephrine monotherapy when the data were pooled together. Pooled data showed that combination therapy was more effective at improving oxygen saturation level (mean difference: −0.70; 95% confidence interval: −1.17 to −0.22, p = 0.004). There was no difference in the risk of serious adverse events in infants treated with the combined epinephrine and corticosteroid therapy. Conclusions: Combination treatment of epinephrine and dexamethasone was ineffective in reducing hospital admission and length of stay among infants with bronchiolitis.

Abstract
Viral bronchiolitis is a common clinical syndrome affecting infants and young children. Concern about its associated morbidity and cost has led to a large body of research that has been summarised in systematic reviews and integrated into clinical practice guidelines in several countries. The evidence and guideline recommendations consistently support a clinical diagnosis with the limited role for diagnostic testing for children presenting with the typical clinical syndrome of viral upper respiratory infection progressing to the lower respiratory tract. Management is largely supportive, focusing on maintaining oxygenation and hydration of the patient. Evidence suggests no benefit from bronchodilator or corticosteroid use in infants with a first episode of bronchiolitis. Evidence for other treatments such as hypertonic saline is evolving but not clearly defined yet. For infants with severe disease, the insufficient available data suggest a role for high-flow nasal cannula and continuous positive airway pressure use in a monitored setting to prevent respiratory failure.

Abstract
Introduction Pressurized metered-dose inhalers (pMDI) such as fluticasone propionate and salmeterol (FP/SAL) are commonly used for the treatment of asthma in the UK. Previously, a budget impact analysis demonstrated that use of FP and formoterol fumarate (FP/FORM) pMDI as an alternative to FP/SAL pMDI, would be a cost-saving option for the UK National Health Service (NHS). This budget impact analysis aimed to update the existing analysis with prescription volume data and real-world evidence since the introduction of FP/FORM to the UK market. Methods Patient Data (IMS Information Solutions UK Ltd) moving annual total (MAT) August 2015 were used to ascertain the number of units of pMDI prescribed. Annual costs to the NHS in terms of drug, administration, monitoring and adverse event costs, were used to estimate the potential budget impact for FP/FORM and FP/SAL. Costs were calculated for current prescription volumes (12% FP/FORM, 88% FP/SAL), and for different prescription volume scenarios (FP/FORM at 0%, 25%, 50% and 100%). Real-world evidence and budget impact at a clinical commissioning group (CCG) level were also considered. Results Total annual costs per person year were less with FP/FORM (£625) than with FP/SAL (£734). Annual costs to the NHS based on the current prescription volumes and clinical trial data were estimated at £210.0M, however, based on real-world evidence, costs were estimated at £179.8M. For all scenarios with increased FP/FORM prescription volumes, the annual total costs to the NHS decreased. This was reflected at a CCG level. Conclusion The use of FP/FORM as an alternative to FP/SAL can result in cost savings for the NHS when assessing drug, administration, monitoring and adverse events costs. The inclusion of data released since the launch of FP/FORM within the budget impact analysis demonstrates that the potential cost savings to the NHS that were previously published are being translated to clinical practice.

Abstract
Inhaled therapy is often considered the cornerstone of asthma management and international guidelines recommend combination therapy of inhaled corticosteroids (ICS) and long-acting-beta2-agonists (LABA) in a large proportion of asthmatic patients. The effectiveness of ICS/LABA is dependent on the correct choice of device and proper inhalation technique, this influences drug delivery and distribution along the bronchial tree, including the most peripheral airways. The fixed combination of beclometasone dipropionate/formoterol fumarate (BDP/FF) is the only extrafine formulation available in pressurized metered dose inhaler (pMDI) and in dry powder inhaler (DPI). Here, we focus on the recent significant advances regarding BDP/FF fixed combination for the treatment of asthma.

Comparison of early effects of budesonide/formoterol maintenance and reliever therapy with fluticasone furoate/vilanterol for asthma patients requiring step-up from inhaled corticosteroid monotherapy. Pulm Pharmacol Ther 2016; 37:15-23. [PMID: 26850307 DOI: 10.1016/j.pupt.2016.01.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Revised: 01/28/2016] [Accepted: 01/31/2016] [Indexed: 11/26/2022]
Abstract
BACKGROUND If asthma patients fail to achieve symptom control using a medium dose of inhaled corticosteroid (ICS) alone, addition of a long-acting β2 agonist (LABA) is the preferred treatment. Currently, there are several combinations of ICS/LABA that are available, each of which has a different property. Here, we aimed to compare the early effects of budesonide/formoterol (BUD/FM; Symbicort(®)) for maintenance and reliever therapy (SMART) with a fixed dose of fluticasone furoate/vilanterol (FF/VI; Relvar(®)). METHODS Inadequately controlled asthma patients (defined as having an Asthma Control Questionnaire, 5-item version [ACQ5] score≥1.5) with a fractional exhaled nitric oxide (FeNO) value > 35 ppb, who had been treated with a medium dose of ICS alone, were enrolled. Patients were randomized into two groups and treated with two inhalations twice-daily of BUD/FM 160/4.5 μg plus as-needed BUD/FM (SMART group, n = 15) or one inhalation once-daily of FF/VI 100/25 μg plus as-needed procaterol (FF/VI group, n = 15) for 4 weeks. Outcomes including FeNO, impulse oscillometry (IOS) parameters and ACQ5 scores were measured at 0, 2 and 4 weeks. RESULTS Both groups showed improvement in airway inflammation, pulmonary function and symptoms from baseline to 2 weeks. From 2 to 4 weeks, the SMART group exhibited continuous improvement in most measured parameters, whereas improvement in the FF/VI group seemed to reach a plateau transiently. Consequently, the SMART group showed significant improvement in the FeNO, IOS parameters (resonance frequency and integrated area of low frequency reactance) and ACQ5 score as compared with the FF/VI group at 4 weeks. CONCLUSION As compared with the FF/VI group, the SMART group achieved a greater improvement in FeNO, small airway parameters regarding IOS and ACQ score, in patients with airway inflammation and uncontrolled symptoms treated with a medium dose of ICS alone. In this 4-week study, these two ICS/LABA combination therapies showed different treatment outcomes; they must be investigated further to clarify suitable patient characters and the long term efficacies for each combination.

Abstract
Fixed dose combinations (FDC) of inhaled corticosteroid (ICS) and long-acting beta agonist (LABA) are well established in asthma treatment. The budesonide/salmeterol (B/S) FDC is now about to reach the market. It is provided as powder in hard capsules of two strengths: 120/20μg and 240/20μg when expressed as delivered doses, equivalent to 150/25μg and 300/25μg when expressed as nominal doses. Its development involved 9 pharmacokinetic (320 subjects), 3 phase II (123 subjects) and 4 phase III (1206 patients with different asthma severity) studies. Delivery is effectuated via low resistance inhaler device, Axahaler®, generating also fine particles targeting the small airways. B/S safety, assessed in 1401 subjects, did not outline novel concerns specific for this FDC. In conclusion, the B/S dry powder FDC can be used for asthma treatment in adults not adequately controlled on ICS alone, or to maintain control of ICS/LABA treated patients, in whom switching to alternative FDC is indicated.

Abstract
INTRODUCTION Since the 1970s, the treatment options for asthma and chronic obstructive pulmonary disease have increasingly relied upon the use of inhaled drug formulations, generally from handheld inhaler devices. The introduction of combinations of a corticosteroid with a long-acting β2 agonist has dramatically transformed the accepted treatment paradigm. This has led to a dramatic increase in the development of novel combinations of inhaled drugs, including long-acting muscarinic antagonists with long-acting β2 agonists, as well as triple combinations, and of devices for their delivery. AREAS COVERED This review considers recent patent filings claiming inhaled drug combinations, or devices delivering them, that are useful in the treatment of asthma and/or chronic obstructive pulmonary disease. EXPERT OPINION The modest level of activity in patent filings relating to inhaled combinations is surprising. Many of the patents are from the major players in the respiratory market segment, with only one inhalation technology specialist showing significant activity. The limited activity from generics companies is explained by the limited range of active ingredients whose use they can usefully claim.

Santus P, Radovanovic D, Paggiaro P, Papi A, Sanduzzi A, Scichilone N, Braido F. Why use long acting bronchodilators in chronic obstructive lung diseases? An extensive review on formoterol and salmeterol. Eur J Intern Med 2015; 26:379-84. [PMID: 26049917 DOI: 10.1016/j.ejim.2015.05.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2015] [Revised: 04/27/2015] [Accepted: 05/01/2015] [Indexed: 10/23/2022]
Abstract
Long-acting β2-adrenoceptor agonists, formoterol and salmeterol, represent a milestone in the treatments of chronic obstructive lung diseases. Although no specific indications concerning the choice of one molecule rather than another are provided by asthma and COPD guidelines, they present different pharmacological properties resulting in distinct clinical employment possibilities. In particular, salmeterol has a low intrinsic efficacy working as a partial receptor agonist, while formoterol is a full agonist with high intrinsic efficacy. From a clinical perspective, in the presence of low β2-adrenoceptors availability, like in inflamed airways, a full agonist can maintain its bronchodilatory and non-smooth muscle activities while a partial agonist may be less effective. Furthermore, formoterol presents a faster onset of action than salmeterol. This phenomenon, combined with the molecule safety profile, leads to a prompt amelioration of the symptoms, and allows using this drug in asthma as an "as needed" treatment in patients already on regular treatment. The fast onset of action and the full agonism of formoterol need to be considered in order to select the best pharmacological treatment of asthma and COPD.

Abstract
Severe asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are chronic lung diseases with a clear need for development of new and more efficient therapy. In preclinical research, the mouse model has been instrumental in advancing our knowledge of the biology and immunology. However, it has been proven rather difficult and time consuming to develop new treatments that can impact on the clinical course of these diseases. Many challenges need to be overcome for upgrading the quality of currently available experimental disease models in order to enhance the translation rate of basic research to clinical practice. Establishment of transgenic mouse overexpressing disease-causing genes may provide tools to discover new pathological pathways and to evaluate the possibility of molecular targeted therapy in chronic lung diseases. Personalized medicine, if developed, might be the solution for 'disease heterogeneity' and for improving clinical outcome.

Budesonide/formoterol maintenance and reliever therapy in asthma control: acute, dose-related effects and real-life effectiveness. Respirology 2014; 20:264-72. [PMID: 25366969 DOI: 10.1111/resp.12425] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2014] [Revised: 08/18/2014] [Accepted: 09/15/2014] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND OBJECTIVE The efficacy of budesonide/formoterol maintenance and reliever therapy (BFMRT) in asthma control is well documented in large randomized controlled trials. However, the acute reliever effects and real-life effectiveness are seldom reported. METHODS This multicenter trial enrolled steroid-naïve, symptomatic asthmatics with baseline exhaled nitric oxide (eNO) of ≥ 40 ppb. There were 120 eligible patients who were randomized and received a dose of inhaled budesonide/formoterol 320/9 μg (lower dose budesonide/formoterol), 640/18 μg (higher dose budesonide/formoterol (HDBF)), or terbutaline (TERB) 1 mg. Inflammatory cells and mediators in induced sputum, eNO and lung function were measured at baseline and 6 h (acute phase). Subsequently, all patients used BFMRT as real-life practice for 24 weeks (maintenance phase). RESULTS In the acute phase, the degree of post-treatment reduction in total eosinophil counts, interleukin-8 and matrix metalloproteinase-9 in induced sputum were significantly greater in group HDBF (vs TERB, P < 0.05). The increase in forced expiratory volume in first second (FEV1 ) in group HDBF was significantly higher (vs LDBF and TERB, P < 0.05) 3 h after dosing. In the maintenance phase, significant improvement of asthma control (presented by eNO, FEV1 and a five-item asthma control questionnaire) in real-life settings was observed at 4 weeks and sustained to the end of study. The rate of patients who followed scheduled visits declined over time (87% at week 4 and 42% at week 24). CONCLUSIONS Budesonide/formoterol as reliever exerts acute, dose-related anti-inflammatory effects and FEV1 improvement in symptomatic asthmatics. BFMRT is effective in asthma control. However, the decrease in long-term follow-up rate remains an issue to overcome in real-life settings.

Abstract
Background Long-acting β2 adrenergic agonists (LABAs) are commonly used combined with inhaled corticosteroids (ICS) to treat asthmatic patients. Previous reports suggest that LABAs have an anti-inflammatory effect in bronchial asthma, and this should be further investigated. The aim of this study was to investigate whether LABAs inhibit allergic airway inflammation and how this occurs. Results We assessed the effect of the LABA formoterol (FORM) on inflammatory cell responses in airway, lung and regional lymph nodes, using an HDM-induced murine allergic asthma model in vivo. The effect of FORM on cytokine production from bone marrow derived dendritic cells (BMDCs) stimulated with HDM was evaluated in vitro. Adoptive transfer of BMDCs pulsed with HDM in the presence or absence of FORM to naïve mice was performed and the inflammatory response to subsequent HDM challenge was analyzed. FORM treatment suppressed HDM-induced changes and caused an increase in the number of eosinophils and neutrophils in bronchoalveolar lavage. The concentration of IL-4 and IL-17 in lung tissue homogenate was elevated and led to an accumulation of IL-4, IL-13, IL-5 and IL-17 producing cells in regional lymph nodes. FORM inhibited the production of IL-6 and IL-23 from BMDCs stimulated with HDM in vitro, and enhanced IL-10 production. The BMDCs adoptive transfer experiment indicated that dendritic cells mediate the effect of FORM, since FORM treatment of BMDCs in vitro attenuated airway inflammation. Conclusion These results suggested that FORM modulates dendritic cell function and attenuates Th2 and Th17 responses induced by HDM. Thus, we propose that the clinical significance of LABAs should be re-investigated taking into account these immune-modulating effects.

Abstract
In the Single combination inhaler as Maintenance And Reliever Therapy (SMART) regimen, asthma patients use a corticosteroid/fast-onset long-acting beta-agonist inhaler as both regular maintenance and reliever therapy. In this multicenter, double-blind randomized controlled trial, Papi et al. have demonstrated that treatment with the combination beclometasone/formoterol hydrofluoroalkane (HFA)-MDI when used as both maintenance and reliever therapy significantly prolongs the time to the first severe asthma exacerbation and reduces severe exacerbations compared with the same fixed dose of maintenance beclometasone/formoterol HFA-MDI with salbutamol MDI for relief. These findings are consistent with those of the prior studies of the SMART regimen with the budesonide/formoterol DPI and extend the evidence for use of the SMART regimen to the extrafine beclometasone/formoterol HFA-MDI, to patients with high baseline reliever use, and to patients in whom the SMART regimen results in a step up, step down or no change in baseline inhaled corticosteroid dose.

Abstract
International guidelines describe asthma control as the main outcome of asthma management. Prevention of symptoms, improved quality of life, and reduction of exacerbations are the main components, consequently decreasing health care costs. However, many of these objectives remain unmet in real life: several surveys show that a large proportion of asthmatic patients are not well controlled despite the efficacy of current available treatment. Several randomized controlled clinical trials indicate that combining inhaled corticosteroids and long-acting β2-agonists, by means of a single inhaler, greatly improves the management of the disease. The results of 9 multicenter phase III clinical studies demonstrate that the fixed combination of fluticasone propionate/formoterol in a single inhaler is effective in terms of lung function and symptom control. These studies highlight the dose flexibility, safety and tolerability of this new inhaled combination. These characteristics meet the recommendations of international guidelines, and the preferences of respiratory physicians who identified these aspects as critical components of a successful asthma therapy. Combination of fluticasone propionate/formoterol in a single inhaler provides potent anti-inflammatory activity of fluticasone propionate and rapid onset of action of the β2-agonist formoterol making this association a viable treatment option both in terms of effectiveness and compliance.

Abstract
Pharmacologic treatment of asthma should be done with a stepwise approach recommended in treatment guidelines. If inhaled corticosteroids (ICSs) alone are not adequate, ICSs in combination with long-acting β-agonists (LABAs) are now established and widely used as the next step in effective controller therapy. Fixed-dose ICS/LABA combinations in a single device are the preferred form of delivery and improve compliance by enabling patients to get symptom relief from the LABA while receiving the anti-inflammatory benefits of ICSs. Fluticasone propionate/formoterol fumarate is one of the newest fixed-dose combinations. It has been in use in Europe in 2012, but is still under regulatory review in the US. Fluticasone is a synthetic ICS with potent anti-inflammatory effects, while formoterol is a selective β2-adrenergic receptor agonist with a rapid onset of bronchodilation within 5-10 minutes and a 12-hour duration of action. Fluticasone/formoterol has shown superior efficacy when compared to fluticasone or formoterol alone in multiple well-designed studies. The combination has shown comparable or "noninferior" benefits in lung function, clinical symptoms, and asthma control when compared with fluticasone and formoterol administered concurrently in separate inhalers. Fluticasone/formoterol provides similar efficacy with fluticasone/salmeterol, but with more rapid symptom relief. It has been compared directly with budesonide/formoterol with comparable results. Fluticasone/formoterol is well tolerated, with no unusual or increased safety concerns versus each individual component or other available ICS/LABA combinations. Fluticasone/formoterol is the latest entry into a relatively crowded market of branded fixed-dose preparations. Upcoming generic fixed-dose combinations and once-daily agents pose significant market challenges. In clinical practice, most practitioners consider all the currently available fixed-dose preparations to be of comparable efficacy and safety.

Abstract
BACKGROUND The fixed combination of extrafine beclomethasone dipropionate and formoterol fumarate (BDP/FF) pMDI (Foster(®)) is approved for treatment of adult asthmatic patients. In order to provide an alternative drug delivery system for BDP/FF to physicians and patients, a dry powder inhaler (NEXThaler(®)) has been developed, capable to deliver extrafine particles to the lungs and therefore improve the dosing of the drugs, especially in patients with poor hand-breath coordination. OBJECTIVE This trial was performed to compare efficacy and safety of extrafine BDP/FF NEXThaler(®) with extrafine BDP/FF pMDI or non-extrafine BDP DPI alone in adult patients with controlled asthma. METHODS In this 8-week randomised, double-blind, parallel-group trial, patients were randomized to receive either extrafine BDP/FF NEXThaler(®) 100/6 μg bid, extrafine BDP/FF 100/6 μg pMDI bid or non-extrafine BDP DPI 100 μg bid. The primary efficacy variable was change from baseline to the entire 8-week randomised treatment period in average pre-dose morning PEF. RESULTS The ITT population comprised 754 patients. Extrafine BDP/FF NEXThaler(®) was non-inferior (pre-defined margin: -15 L/min) relative to extrafine BDP/FF pMDI (mean difference: -1.84; 95% CI: -6.73, 3.05) in terms of the primary efficacy variable, change from baseline in average pre-dose morning PEF. Statistical superiority of both extrafine BDP/FF formulations over non-extrafine BDP DPI was demonstrated for the primary efficacy variable (providing evidence of assays sensitivity of the trial), ACQ score and percentage of rescue medication use-free days. No significant safety signals were observed. CONCLUSION NEXThaler(®) is an effective and well-tolerated delivery device for treatment of patients with asthma who need a regular treatment.

Abstract
Inhaled pharmaceuticals are formulated and delivered differently according to the therapeutic indication. However, specific device-formulation coupling is often fickle, and new medications or indications also demand new strategies. The discontinuation of chlorofluorocarbon propellants has seen replacement of older metered dose inhalers with dry powder inhaler formulations. High-dose dry powder inhalers are increasingly seen as an alternative dosage form for nebulised medications. In other cases, new medications have completely bypassed conventional inhalers and been formulated for use with unique inhalers such as the Staccato® device. Among these different devices, integration of software and electronic assistance has become a shared trend. This review covers recent device and formulation advances that are forming the current landscape of inhaled therapeutics.

Abstract
Novel inhaled therapeutics including antibiotics, vaccines and anti-hypertensives, have led to innovations in designing suitable delivery systems. These emerging design technologies are in urgent demand to ensure high aerosolisation performance, consistent efficacy and satisfactory patient adherence. Recent vibrating-mesh and software technologies have resulted in nebulisers that have remarkably accurate dosing and portability. Alternatively, dry powder inhalers (DPIs) have become highly favourable for delivering high-dose and single-dose drugs with the aid of advanced particle engineering. In contrast, innovations are needed to overcome the technical constrains in drug-propellant incompatibility and delivering high-dose drugs with pressurised metered dose inhalers (pMDIs). This review discusses recent and emerging trends in pulmonary drug delivery systems.

Abstract
Background: This study investigated the effect of combining oral dexamethasone with either nebulized racemic epinephrine or salbutamol compared to bronchodilators alone for the treatment of infants with bronchiolitis. Materials and Methods: This was a double-blind, randomized controlled trial on infants (1 to 12 months) who were diagnosed in the emergency department with moderate-to-severe bronchiolitis. The primary outcome was the rate of hospital admission within 7 days of the first dose of treatment, and the secondary outcomes were changes in respiratory distress assessment instrument score, heart rate, respiratory rate, and oxygen saturation (O2 Sat) over a 4-hour observation period. Infants (n = 162) were randomly assigned to four groups: A (dexamethasone + racemic epinephrine) = 45, B (placebo and racemic epinephrine) =39, C (dexamethasone and salbutamol) = 40, or D (placebo and salbutamol) = 38. Results: Patients who had received dexamethasone + epinephrine exhibited similar admission rates compared to placebo + epinephrine or salbutamol (P = 0.64). Similarly, no statistically significant difference was observed in the rate of hospitalization for patients who received dexamethasone + salbutamol compared to those who received placebo + epinephrine or salbutamol (P = 0.51). Clinical parameters were improved at the end of the 4-hour observation period for all treatment groups. Treatment with dexamethasone + epinephrine resulted in a statistically significant change in HR over time (P < 0.005) compared to the other groups. Conclusions: This study adds to a body of evidence suggesting that corticosteroids have no role in the management of bronchiolitis for young infants who are first time wheezers with no risk of atopy.

Abstract
The combination of an inhaled corticosteroid and a long acting beta-2 agonist is indicated for the regular treatment of persistent moderate-to-severe asthmatics whose asthma is not controlled by inhaled corticosteroids and the occasional use of a short acting beta-2 agonist. The aim of this review is to give an overview of the rationale of combining formoterol and fluticasone and to analyze the clinical data concerning a new fixed combination of fluticasone and formoterol in a pressurised metered-dose inhaler with a dose counter (Flutiform(®)) that was approved for the treatment of asthma in France in 2013. The clinical studies provide evidence that combined fluticasone/formoterol is more efficacious than fluticasone or formoterol given alone, and provides similar improvements in lung function to fluticasone (Flixotide(®)) and formoterol (Foradil(®)) administered concurrently. The combination of fluticasone/formoterol gave a more rapid bronchodilatation than the combination fluticasone/salmeterol. As a whole, the combination of fluticasone/formoterol had similar efficacy and tolerability profiles to the combinations of either budesonide/formoterol or fluticasone/salmeterol.

Combination corticosteroid/β-agonist inhaler as reliever therapy: a solution for intermittent and mild asthma? J Allergy Clin Immunol 2014; 133:39-41. [PMID: 24369798 DOI: 10.1016/j.jaci.2013.10.053] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2013] [Revised: 10/25/2013] [Accepted: 10/30/2013] [Indexed: 11/20/2022]
Abstract
The recommended treatment of mild asthma is regular maintenance inhaled corticosteroids (ICSs) with a short-acting β-agonist as a separate inhaler used when needed for symptom relief. However, the benefits of regular ICS use in actual clinical practice are limited by poor adherence and low prescription rates. An alternative strategy would be the symptom-driven (as-required or "prn") use of a combination ICS/short-acting β-agonist or ICS/long-acting β-agonist inhaler as a reliever rather than regular maintenance use. The rationale for this approach is to titrate both the ICS and β-agonist dose according to need and enhance ICS use in otherwise poorly adherent patients who overrely on their reliever β-agonist inhaler. This strategy will only work if the β-agonist component has a rapid onset of action for symptom relief. There is evidence to suggest that this regimen has advantages over regular ICS therapy and might represent an effective, safe, and novel therapy for the treatment of intermittent and mild asthma. In this commentary we review this evidence and propose that randomized controlled trials investigating different combination ICS/β-agonist inhaler products prescribed according to this regimen in intermittent and mild asthma are an important priority.

Abstract
Background: Recently, higher efficacy of the combination of long-acting beta2-adrenoceptor agonist and inhaled corticosteroids on controlling asthma symptoms has been hypothesized. This study aimed to examine the clinical effects of the combination of Budesonide with formoterol (Symbicort) and Budesonide (Pulmicort) alone in persistent asthma. Materials and Methods: In a randomized double-blinded clinical trial, 76 patients with definite diagnosis of moderate-to-severe asthma were randomized to receive Pulmicort 180 mcg/inhalation two puffs twice daily, or receive Symbicort 80/4.5 mg/inhalation two puffs twice daily, or receive Symbicort 160/4.5 mg/inhalation two puffs twice daily for 3 months. All participants were initially evaluated by spirometry for assessing respiratory parameters and also the level of asthma control was assessed by Asthma Control Test (ACT). Results: More significant improvement in spirometry parameters, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, as well as in peak expiratory flow (PEF) in both groups of Symbicort with the regimens 80/4.5 mg/inhalation or 160/4.5 mg/inhalation 2 puffs twice daily compared with Pulmicort group, ACT score was significantly improved in Symbicort group with the regimens 160/4.5 mg/inhalation compared with both Symbicort groups with lower dosage and Pulmicort group. Response to treatment in PEF parameter and also in ACT level was significantly more in those who received Symbicort with the regimens 160/4.5 mg/inhalation compared with other two interventional groups adjusted for gender and age. Conclusion: Symbicort with the regimens 160/4.5 mg/inhalation has higher efficacy in reducing asthma symptom and improving its control compared with low doses of this drug and with Pulmicort.

Abstract
OBJECTIVES This study investigated the efficacy and tolerability of a new asthma therapy combining fluticasone propionate and formoterol fumarate (fluticasone/formoterol)*, administered twice daily (BID) via a single aerosol inhaler, compared with fluticasone propionate (fluticasone) or formoterol fumarate (formoterol) administered alone, in patients with mild to moderate asthma. METHODS Patients aged ≥12 years were evenly randomized to 12 weeks of treatment with fluticasone/formoterol (100/10 µg BID), fluticasone (100 µg BID), or formoterol (10 µg BID), in this multicenter, double-blind, parallel-group, study. The 2 coprimary end points were: (1) change in forced expiratory volume in 1 second (FEV(1)) from morning predose at baseline to predose at week 12 for the comparison of the combination product with formoterol alone; and (2) change in FEV(1) from morning predose at baseline to 2 hours postdose at week 12 for the comparison of the combination product with fluticasone alone. The secondary objective was to demonstrate the efficacy of fluticasone/formoterol using other pulmonary function tests and clinical end points. Tolerability was assessed based on adverse events, clinical laboratory tests and vital sign evaluations. RESULTS Statistically significant differences were demonstrated for the 2 coprimary end points. Fluticasone/formoterol combination therapy showed significantly greater improvements from baseline to end of study in the change in predose FEV(1) compared with formoterol (least squares [LS] mean treatment difference, 0.118 L [95% CI, 0.034-0.201; P = 0.006]) and the change in predose compared with 2 hours postdose FEV(1) versus fluticasone (LS mean treatment difference, 0.122 L [95% CI, 0.040-0.204; P = 0.004]). Statistical analyses of the secondary efficacy endpoints revealed that evaluations of lung function, asthma exacerbations, asthma symptoms, rescue medication use and asthma control were supportive overall of the superior efficacy of fluticasone/formoterol combination therapy compared with its individual components; were supportive overall of the efficacy of fluticasone/formoterol combination therapy compared with its individual components. Since the secondary endpoints were analyzed using the sequential gatekeeper approach, only the mean change from baseline to final week in morning peak expiratory flow rate between the combination-therapy and formoterol groups returned statistically significant results (least squares mean difference, 20.05 [95% CI, 7.631-32.472; P = 0.002]). The fluticasone/formoterol combination therapy had a good tolerability profile over the 12-week treatment period. CONCLUSIONS Fluticasone/formoterol had a good tolerability profile and showed statistically superior efficacy for the two co-primary endpoints compared to fluticasone or formoterol, in adolescents and adults with mild to moderate asthma.

Abstract
The effect of duration of administration of fluticasone propionate and salmeterol on tracheal responsiveness to ovalbumin and total and differential white blood cell in sensitized guinea pig was examined. Six groups of guinea pigs (n = 7) were sensitized to ovalbumin. Three groups of them were subjected to inhaled fluticasone propionate and salmeterol, one group during sensitization (A), one group after that (for 18 days, B), and the other one during sensitization but with 18 days delay before measurements (C). Three other groups were treated with placebo in the same manner. The tracheal responsiveness to ovalbumin and total and differential white blood cells of three placebo groups were significantly higher than those of control group (P < 0.001 for all cases). Tracheal responsiveness to ovalbumin and total and differential white blood cell in treated groups with fluticasone propionate and salmeterol were significantly decreased compared to those of placebo groups (nonsignificant to P < 0.001). The improvement in all variables in treatment groups A and C were more pronounced than group B. The results showed that fluticasone propionate and salmeterol had a prevention effect on tracheal hyperresponsiveness to ovalbumin and lung inflammation which was more pronounced when administered during than after sensitization.

Pulm Pharmacol Ther 2014; 27:190-6. [PMID: 24388868 DOI: 10.1016/j.pupt.2013.12.003] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2013] [Revised: 12/20/2013] [Accepted: 12/23/2013] [Indexed: 12/15/2022]
Abstract
BACKGROUND If asthma patients fail to achieve symptom control using a medium dose of inhaled corticosteroid (ICS) alone, adding a long-acting β2 agonist (LABA) is the preferred treatment. We aimed to compare the effect of two widely available ICS/LABA combinations in these patients in real-life conditions: budesonide/formoterol (BUD/FM; Symbicort(®)) for maintenance and reliever therapy (SMART) and a fixed dose of fluticasone propionate/salmeterol (FP/SM). METHODS Inadequately controlled asthma patients treated with a medium dose of ICS alone, with an Asthma Control Questionnaire (ACQ) score >0.75 and using a short-acting β2-agonist (SABA) 2-6 occasions/week, were enrolled. Patients were randomized into two groups and treated with two inhalation twice-daily BUD/FM 160/4.5 μg plus as-needed BUD/FM (SMART group, n = 15) or one inhalation twice-daily FP/SM 250/50 μg plus as-needed procaterol (FP/SM group, n = 15) for 8 weeks. RESULTS Both groups showed significant improvement in airway inflammation, pulmonary functions and symptoms from baseline. The SMART group showed significant improvement in the fraction of nitric oxide, ACQ score, rescue medication use and small airway parameter R5-R20 measured by impulse oscillometry compared with the FP/SM group. CONCLUSION For stepping up treatment from ICS alone to an ICS/LABA combination, SMART is preferable for controlling asthma symptoms by suppressing airway inflammation and improving small airway impairment compared with a fixed dose of FP/SM. It may be achieved by the property of BUD/FM itself and as-needed use, but the degree of each contribution must be investigated further.

Abstract
OBJECTIVE To demonstrate the efficacy and safety of fluticasone propionate/formoterol fumarate (flutiform) in a pressurised metered-dose inhaler (pMDI) compared to two formulations of the fluticasone propionate component (Skyepharma fluticasone [SKP FP] or Flovent, GlaxoSmithKline [GSK FP]) in adults and adolescents with moderate-to-severe asthma. METHODS Patients included in the study were ≥12 years, with symptomatic asthma for ≥1 year, steroid-requiring, had a forced expiratory volume in the first second (FEV1) of 40% to 80% (inclusive) of predicted normal values, and documented reversibility within 12 months of the study. Albuterol/salbuterol was given as rescue medication. The primary efficacy endpoint was the change in FEV1 from morning pre-dose at baseline (week 0) to 2 hours post-dose at week 12 for fluticasone/formoterol compared to SKP FP and, additionally, compared to GSK FP. RESULTS Fluticasone/formoterol was demonstrated to be statistically significantly superior to SKP FP. The least squares (LS) mean difference in FEV1 from baseline pre-dose to 2 hours post-dose at week 12 was 0.161 L (95% CI: 0.078, 0.245, p < 0.001). Fluticasone/formoterol also demonstrated superior efficacy against GSK FP (LS mean difference = 0.185 L, 95% CI: 0.102, 0.268, p < 0.001). Results from multiple secondary and tertiary efficacy endpoints assessing lung function, asthma symptoms, exacerbations and rescue medication use supported a superior efficacy of the fluticasone/formoterol combination over both fluticasone formulations. Treatment-emergent adverse events were lowest in the fluticasone/formoterol group (32.9%) compared to SKP FP (39.7%) or GSK FP (40.4%). CONCLUSIONS Results from this study demonstrate that fluticasone/formoterol 250/10 µg b.i.d. provides superior efficacy compared to fluticasone alone for the management of moderate-to-severe asthma, with a safety profile similar to that of fluticasone monotherapy.

Abstract
BACKGROUND The potent inhaled corticosteroid, fluticasone propionate (fluticasone), and the long-acting β2-agonist with a rapid onset of action, formoterol fumarate (formoterol), have now been combined in a single aerosol inhaler, fluticasone/formoterol (flutiform). This study investigated the efficacy and safety of fluticasone/formoterol combination therapy compared with its individual components administered concurrently via two separate inhalers. METHODS Patients ≥ 12 years (N = 210) with mild to moderate-severe persistent, reversible asthma were evenly randomised to 12 weeks of treatment (b.i.d.) with fluticasone/formoterol combination therapy (100/10 μg b.i.d. or 250/10 μg b.i.d.) or fluticasone plus formoterol (Flixotide Evohaler, pMDI, Flovent [HFA]; Foradil, DPI, Foradil Aerolizer) administered concurrently (fluticasone + formoterol; 100 μg + 12 μg b.i.d. or 250 μg + 12 μg b.i.d.) in an open-label, parallel-group, multicentre study. The primary objective of this study was to show non-inferiority of fluticasone/formoterol compared with fluticasone + formoterol based on mean post-dose FEV1. RESULTS The mean FEV1 30-60 minutes post-dose on Day 84 was approximately 2.6 L in both the fluticasone/formoterol combination and the fluticasone + formoterol treatment groups (per protocol sets; treatment difference least squares (LS) mean: -0.03 L; 95% CI: -0.148, 0.081). The lower limit of the 95% CI (-0.148 L) was above the non-inferiority threshold of ≥-0.2 L. Analyses of other pulmonary function tests, patient reported outcomes, rescue medication use, asthma exacerbations and quality of life questionnaires were also comparable. The safety profiles of the two study groups were similar overall. TRIAL REGISTRATION Fluticasone/formoterol combination therapy had comparable efficacy to its individual components administered concurrently, when measured by post-dose FEV1 in patients aged ≥ 12 years with mild to moderate-severe asthma. The safety and tolerability profile of fluticasone/formoterol combination therapy was similar to that of its individual components administered concurrently. Although this was an open-label study, the results remain compelling: the primary efficacy measure was a physical endpoint and study statisticians were blinded to treatment allocations until analysis was completed.

Abstract
BACKGROUND The Single combination budesonide-formoterol inhaler Maintenance And Reliever Therapy (SMART) regimen reduces severe asthma exacerbations in patients, but whether the high doses of corticosteroid and β agonist increase the risk of adverse effects with both short-term and cumulative exposure is not certain. Our aim was to investigate whether the SMART regimen would reduce the risk of overuse of β agonist, reduce the likelihood of patients to seek medical review when such episodes occurred, and if any reduction in severe asthma exacerbations would be at the cost of a higher burden of systemic corticosteroid. METHODS In this 24-week trial undertaken at four primary health-care practices and one hospital in New Zealand, patients (aged 16-65 years) with a recent asthma exacerbation were randomly assigned in a 1:1 ratio to the SMART or standard fixed-dose regimen. Treatment in the SMART group consisted of two actuations of budesonide-formoterol (200 μg and 6 μg, respectively, per actuation) twice daily, delivered through a combination metered dose inhaler (MDI), with one extra actuation as needed for relief of symptoms; treatment in the standard group consisted of two actuations of budesonide-formoterol (200 μg and 6 μg, respectively, per actuation) twice daily through a combination MDI with one to two actuations of salbutamol (100 μg per actuation) by MDI as needed for relief of symptoms. MDIs were monitored electronically to measure actual use of medication. The allocation sequence for randomisation was computer generated, with a block size of eight per site. Participants, investigators, and the statistician were not masked to group assignment. The primary outcome was the proportion of participants with at least one high-use episode of β agonist (more than eight actuations per day of budesonide-formoterol in addition to the four maintenance doses in the SMART group or more than 16 actuations per day of salbutamol in the standard group). Analysis was by intention to treat. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12610000515099. FINDINGS 303 patients were randomly assigned to the SMART (n=151) or standard group (n=152). No significant difference was noted between the SMART and standard groups in the proportion of participants with at least one high-use episode of β agonist (84 [56%] vs 68 [45%], respectively, relative risk 1·24 [95% CI 0·99-1·56]; p=0·058). There were fewer days of high use in the SMART group (mean 5·1 days [SD 14·3] vs 8·9 days [20·9], relative rate 0·58 [0·39-0·88]; p=0·01). Of the patients who had at least one high-use episode, those in the SMART group had fewer days of high use without medical review (8·5 days [17·8] vs 18·3 days [24·8], 0·49 [0·31-0·75]; p=0·001). The SMART regimen resulted in higher inhaled corticosteroid exposure (943·5 μg budesonide per day [1502·5] vs 684·3 μg budesonide per day [390·5], respectively; ratio of means 1·22 [1·06-1·41]; p=0·006), but reduced oral corticosteroid exposure (77·5 mg prednisone [240·5] vs 126·6 mg prednisone [382·1], respectively; p=0·011), with no significant difference in composite systemic corticosteroid exposure (793·7 mg prednisone equivalent per year [893·1] vs 772·1 mg prednisone equivalent per year [1062·7], respectively; 1·03 [0·86-1·22]; p=0·76). Participants in the SMART group had fewer severe asthma exacerbations (35 [weighted mean rate per year 0·53] vs 66 [0·97]; relative rate 0·54 [0·36-0·82]; p=0·004). INTERPRETATION The SMART regimen has a favourable risk-to-benefit profile and can be recommended for use in adults at risk of severe asthma exacerbations.

Abstract
BACKGROUND The inhaled corticosteroid, fluticasone propionate, and the long-acting β(2)-adrenergic agonist, formoterol fumarate, are both highly effective treatments for bronchial asthma. This study (NCT00393952/EudraCT number: 2006-005989-39) compared the efficacy and safety of fluticasone/formoterol combination therapy (flutiform(®); 250/10 μg) administered twice daily (b.i.d.) via a single aerosol inhaler, with the individual components (fluticasone 250 μg b.i.d.; formoterol 10 μg b.i.d.), in adult and adolescent patients with moderate-to-severe asthma. METHODS This was a 12-week, double-blind, randomised, parallel-group, multicentre, placebocontrolled phase 3 study. The co-primary efficacy endpoints were: i) the mean change in the forced expiratory volume in the first second (FEV(1)) from morning pre-dose at baseline to pre-dose at week 12 (fluticasone/formoterol 250/10 μg vs. formoterol), ii) the mean change in FEV(1) from morning pre-dose at baseline to 2 h post-dose at week 12 (fluticasone/formoterol 250/10 μg vs. fluticasone), and iii) the number of patients who discontinued prematurely due to lack of treatment efficacy (fluticasone/formoterol 250/10 μg vs. placebo). The secondary endpoints included measures of lung function, disease control, and asthma symptoms. Safety was assessed based on adverse events, vital signs, and clinical laboratory evaluations. RESULTS Overall, 395 (70.9%) patients completed the study. Fluticasone/formoterol 250/10 μg b.i.d. was superior to the individual components and placebo for all three co-primary endpoints and demonstrated numerically greater improvements for multiple secondary efficacy analyses. Fluticasone/formoterol combination therapy had a good safety profile over the 12 weeks. CONCLUSION Fluticasone/formoterol combination therapy will provide clinicians with an efficacious alternative treatment option for patients with moderate-to-severe asthma.

Abstract
Background Budesonide/formoterol used for both maintenance and reliever therapy has been shown to benefit patients with persistent asthma. We evaluated patient satisfaction and asthma control among Malaysian patients prescribed budesonide/formoterol as single maintenance and reliever therapy in a real-life clinical practice. Methods Adult patients diagnosed with partially controlled or uncontrolled asthma were recruited in a 6-month, prospective, open-label study involving ten hospital-based chest clinics in Malaysia. Patients were prescribed one or two inhalations of budesonide/formoterol Turbuhaler (160/4.5 μg per inhalation) twice daily as maintenance therapy and additional inhalation as reliever therapy. Maintenance doses were decided by physicians based on Global Initiative for Asthma-defined treatment objectives. The primary outcome measure was the change in mean Satisfaction with Asthma Treatment Questionnaire (SATQ) scores from baseline to an average of 3 months and 6 months. Secondary outcome was the change in mean Asthma Control Questionnaire 5-item version (ACQ-5) scores from baseline to an average of 3 months and 6 months and the proportion of patients achieving the minimum clinically important difference. Results Of 201 eligible patients recruited, 195 completed the study. Overall, SATQ mean (standard deviation) score was significantly improved from 5.1 (0.76) at baseline to 5.5 (0.58) (P < 0.001). The increase was observed in all domains of SATQ and had occurred at 3 months for most patients. ACQ-5 mean (standard deviation) score was significantly reduced from 2.2 (1.13) at baseline to 1.2 (0.95) (P < 0.001). A total of 132 (67.7.1%) patients had achieved the minimal clinically important difference (≥0.5) of ACQ-5 scores at study end. Conclusion In a nationwide study, budesonide/formoterol maintenance and reliever therapy achieved greater patient satisfaction and better asthma control compared with previous conventional asthma regimes among Malaysian patients treated in a real-life practice setting. Such an approach may represent an important treatment alternative for our local patients with persistent asthma.

Abstract
BACKGROUND AND PURPOSE Muscarinic acetylcholine receptors (mAChRs) and β-adrenoceptors in the airways and lungs are clinically important in chronic obstructive pulmonary disease (COPD) and asthma. However, the quantitative and qualitative estimation of these receptors by radioligand binding approaches in human airways has not yet been reported because of tissue limitations. EXPERIMENTAL APPROACH The regional distribution and relative proportion of mAChR and β-adrenoceptor subtypes were evaluated in human bronchus and lung parenchyma by a tissue segment binding method with [(3)H]-N-methylscopolamine ([(3)H]-NMS) for mAChRs and [(3)H]-CGP-12,177 for β-adrenoceptors. Functional responses to carbachol and isoprenaline were also analysed in the bronchus. KEY RESULTS The M(3) subtype predominantly occurred in the bronchus, but the density decreased from the segmental to subsegmental bronchus, and was absent in lung parenchyma. On the other hand, the M(1) subtype occurred in the lung only, and the M(2) subtype was distributed ubiquitously in the bronchus and lungs. β(2)-adrenoceptors were increased along the airways, and their densities in the subsegmental bronchus and lung parenchyma were approximately twofold higher than those of mAChRs in the same region. β(1)-adrenoceptors were also detected in lung parenchyma but not in the bronchus. The muscarinic contractions and adrenoceptor relaxations in both bronchial regions were mediated through M(3)-mAChRs and β(2)-adrenoceptors, respectively. CONCLUSIONS AND IMPLICATIONS From the present radioligand binding approach with intact tissue segments, we constructed a distribution map of mAChRs and β-adrenoceptors in human bronchus and lung parenchyma for the first time, providing important evidence for future pharmacotherapy and new drug development for respiratory disorders.

Abstract
OBJECTIVES The inhaled corticosteroid fluticasone propionate (fluticasone) and the long-acting β₂ agonist formoterol fumarate (formoterol) have been combined in a single aerosol inhaler fluticasone/formoterol (flutiform(®)). This study compared the efficacy and safety of fluticasone/formoterol with the combination product budesonide/formoterol (Symbicort(®) Turbohaler(®)). METHODS A randomized, double-blind, double-dummy, multicenter, Phase 3 study comprising a 7- (± 3) day screening, 2-4-week run-in, and 12-week treatment periods. Patients aged ≥ 12 years with moderate to severe persistent asthma for ≥ 6 months before screening and forced expiratory volume in one second (FEV₁) 50-80% predicted and ≥ 15% reversibility following salbutamol inhalation were randomized to fluticasone/formoterol 250/10 μg twice daily (n = 140) or budesonide/formoterol 400/12 μg twice daily (n = 139). RESULTS Fluticasone/formoterol was comparable to budesonide/formoterol with respect to the primary endpoint, change in pre-dose FEV₁ from baseline to Week 12. The LS mean treatment difference was -0.044 L, with a lower 95% confidence interval (CI) greater than the pre-defined non-inferiority limit of -0.2 L (95% CI: -0.130, 0.043 L; p < 0.001). Non-inferiority was also demonstrated for the secondary endpoints mean change in FEV₁ from baseline (pre-dose) to 2 hours post-dose at Week 12, and discontinuations due to lack of efficacy. Similar results were obtained for both treatment groups for all other secondary endpoints. Fluticasone/formoterol had a good safety profile that was comparable with budesonide/formoterol. CONCLUSIONS This study demonstrated comparable efficacy of fluticasone/formoterol to budesonide/formoterol in terms of the primary endpoint, change in pre-dose FEV₁ from baseline to Week 12. This was supported by comparable results for both treatments for all secondary endpoints.

Abstract
BACKGROUND The long-term safety of a new asthma therapy combining fluticasone propionate and formoterol fumarate (fluticasone/formoterol; flutiform(®)) was assessed. METHOD In an open-label study, mild to moderate-severe asthmatics (≥12 years; N=472) were treated twice daily with fluticasone/formoterol 100/10 μg (n=224) or 250/10 μg (n=248) for 6 months (n=256) or 12 months (n=216). The primary and secondary objectives were the long-term safety and efficacy of fluticasone/formoterol, respectively. RESULTS In total, 413 (87.5%) patients completed the study (of which 175 participated for 12 months). Adverse events (AEs) were reported by 174 patients (36.9%): 67 (29.9%) in the 100/10 μg group and 107 (43.1%) in the 250/10 μg group. The most common AEs (>2%) were nasopharyngitis, dyspnea, pharyngitis, and headache; the majority were mild to moderate. Only 18 (3.8%) patients reported AEs considered study drug-related. Five patients per group experienced 12 serious AEs; none was study medication-related. Asthma exacerbations were reported by 53 patients (11.2%): 46 mild to moderate and nine severe. Clinical laboratory tests and vital signs showed no abnormal trends or clinically important or dose-response-related changes. The efficacy analyses showed statistically significant improvements at every time point throughout the study period at both doses. CONCLUSION Fluticasone/formoterol had a good safety and efficacy profile over the 6- and 12-month study periods.
