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

COPD imposes considerable worldwide burden in terms of morbidity and mortality. In recognition of this, there is now extensive focus on early diagnosis, secondary prevention, and optimizing medical management of the disease. While established guidelines recognize different grades of disease severity and offer a structured basis for disease management based on symptoms and risk, it is becoming increasingly evident that COPD is a condition characterized by many phenotypes and its control in a single patient may require clinicians to have access to a broader spectrum of pharmacotherapies. This review summarizes recent developments in COPD management and compares established pharmacotherapy with new and emerging pharmacotherapies including long-acting muscarinic antagonists, long-acting β-2 sympathomimetic agonists, and fixed-dose combinations of long-acting muscarinic antagonists and long-acting β-2 sympathomimetic agonists as well as inhaled cortiocosteroids, phosphodiesterase inhibitors, and targeted anti-inflammatory drugs. We also review the available oral medications and new agents with novel mechanisms of action in early stages of development. With several new pharmacological agents intended for the management of COPD, it is our goal to familiarize potential prescribers with evidence relating to the efficacy and safety of new medications and to suggest circumstances in which these therapies could be most useful.

A new pediatric fixed combination of beclometasone dipropionate (BDP) 50 μg and formoterol fumarate (FF) 6 μg via pressurized metered-dose inhaler (pMDI) (CHF1535, Chiesi, Italy) was investigated. In a double-blind, randomized, placebo-controlled, cross-over study, a single CHF1535 administration using AeroChamber Plus™ spacer device (2 actuations, total dose BDP 100 μg/FF 12 μg) was compared to the same pMDI free combination in 56 asthmatic children aged ≥ 5 and < 12 years. Primary efficacy variable was forced expiratory volume during the first second (FEV1) area under the curve corrected by time over 12 h following morning dose (AUC0-12h). Further CHF1535 doses (50 μg/6 μg, 100 μg/12 μg, and 200 μg/24 μg) were also explored. Adverse events, electrocardiogram, and vital signs were monitored for safety. CHF1535 was non-inferior to free combination [adjusted mean difference (95% CI) 0.004 L (− 0.050, 0.041] with lower confidence limit greater than the limit set at 0.1 L. FEV1 AUC0-12h of each CHF1535 dose vs placebo were 0.037 L (p = 0.160), 0.119 L (p < 0.001), and 0.094 (p < 0.001) for 50/6, 100/12, and 200/24, respectively. No safety signals were found.Conclusion: CHF1535 was as effective as free combination BDP/FF, with a trend towards a dose-related response. All treatments were safe.Trial registration: ClinicalTrials.gov ID: NCT01584492What is Known:•Inhaled pressurized metered-dose solutions (pMDI) are the preferred treatment for pediatric asthma.•Combination therapy of inhaled corticosteroids and long-acting β2- agonists is a well-established approach to control airway inflammation and airway obstruction also in pediatric patients.What is New:•A novel pediatric pMDI fixed combination of beclomethasone dipropionate 50 μg and formoterol fumarate 6 μg (CHF 1535) was non-inferior to the free combination at the same dose in pulmonary function over the 12-h post-dose period in asthmatic children, with trend towards a dose-related response.

The use of inhaled, fixed-dose, long-acting muscarinic antagonists (LAMA) combined with long-acting, beta -adrenergic receptor agonists (LABA) has become a mainstay in the maintenance treatment of chronic obstructive pulmonary disease (COPD). One of the fixed-dose LAMA/LABA combinations is the dry powder inhaler (DPI) of umeclidinium bromide (UMEC) and vilanterol trifenatate (VI) (62.5 µg/25 µg) approved for once-a-day maintenance treatment of COPD. This paper reviews the use of fixed-dose combination LAMA/LABA agents focusing on the UMEC/VI DPI inhaler in the maintenance treatment of COPD. The fixed-dose combination LAMA/LABA inhaler offers a step beyond a single inhaled maintenance agent but is still a single device for the COPD patient having frequent COPD exacerbations and persistent symptoms not well controlled on one agent. Currently available clinical trials suggest that the once-a-day DPI of UMEC/VI is well-tolerated, safe and non-inferior or better than other currently available inhaled fixed-dose LAMA/LABA combinations for COPD.

The aim of this study was to evaluate prescription patterns of antiasthmatic medications in ambulatory care, guideline adherence by physician specialties and medical institutions, and the rate of hospitalization and emergency department visits due to asthma exacerbation. The ambulatory visits between 2000 and 2010 from the Taiwan Longitudinal Health Insurance Database 2000 were analyzed for prescription trends. Seven classes of antiasthmatic medications were identified for prescription trend analysis. Prescription patterns of different medical institutions and physician specialties were further evaluated. We studied 4495 patients with newly diagnosed asthma in 2000. Estimates indicated an increased use in fixed-dose combination of inhaled corticosteroids and long-acting β2-agonists (3.6% in 2002 to 28.8% in 2010) with decreased use of inhaled corticosteroids (14.5% in 2001 to 7.3% in 2010). Xanthine was still the most frequently used medication for asthmatic patients (60.2% in 2001 and 45.2% in 2010). Another marked increase was the use of leukotriene receptor antagonists (2.6% in 2001 to 6.0% in 2010). In the studied population, the rate of hospital admission or emergency department visit moderately decreased from 1.42% to 0.59% during 10 years. Physicians in medical centers and regional hospitals, as well as asthma specialists, dominated the increased use of fixed-dose combinations of inhaled corticosteroids and long-acting β2-agonists and leukotriene receptor antagonists. Physicians in academic medical centers and asthma specialists achieved better adherence to the core recommendations of the international guidelines for asthma management. The reasons for guideline nonadherence among physicians in district hospitals and primary care clinics deserve health care professionals’ attention and require further investigation.

The high-strength formulation of extrafine beclometasone dipropionate/formoterol fumarate (BDP/Form) 200/6 µg has been developed to step up inhaled corticosteroid treatment, without increasing the dose of the bronchodilator, in patients who are not controlled with previous therapies. Two clinical studies have evaluated efficacy of high-strength BDP/Form as compared with another high-dose fixed combination and BDP monotherapy. Overall, data show that BDP/Form 200/6 μg improves lung function and has beneficial effects on symptoms, use of rescue medication and asthma control, with an acceptable safety profile comparable with that of high-dose fluticasone propionate/salmeterol. Therefore, BDP/Form 200/6 μg could be considered as an effective and safe treatment for patients with asthma who are not adequately controlled with high doses of inhaled corticosteroid monotherapy or medium doses of inhaled corticosteroid/long-acting β2-agonist combinations.

Chronic obstructive pulmonary disease (COPD) is a progressive, debilitating disorder that results in frequent exacerbations and impacts quality of life. It represents a growing burden of health care cost, both from societal and economic perspectives. Short- and long-acting bronchodilators remain the mainstay of therapy in COPD patients. New fixed-dose combination inhalers with novel pharmacological combinations of long-acting β2-agonists and muscarinic antagonists and delivered once-daily through a variety of devices are currently being developed and licensed for the treatment of COPD. There is mounting research suggesting that combining a fixed dose of a β2-agonist and a muscarinic antagonist achieves better bronchodilation and clinical outcomes compared with either agent alone. These once-daily dosing inhalers are anticipated to impact favorably on patient preference and compliance. This review examines the fixed-dose combination of tiotropium bromide and olodaterol delivered by a Respimat(®) Soft Mist™ inhaler at doses of 2.5/5 μg and 5/5 μg in moderate-to-very-severe COPD, and its potential role in COPD compared with other long-acting β2-agonist with long-acting muscarinic antagonist combinations and delivery devices.

Current asthma management guidelines emphasize the importance of disease control. Although effective drug therapies are available, real-life data indicate that the general level of asthma control is still low. Fixed-dose combinations of inhaled corticosteroids/long-acting beta2-agonists (ICS/LABAs) are now increasingly used in the management of asthma. A number of studies have compared the clinical benefits of ICS/LABA fixed combinations with the monocomponents administered using two separate inhalers. We conducted a database search to identify all published studies that have assessed whether fixed-dose combinations achieve greater asthma control compared with administration by separate inhalers. Among fixed combinations, only extrafine beclomethasone/formoterol provided significantly greater asthma control compared with separate inhalers administered as larger aerosol particles. This greater effect may be explained by increased delivery to the small airways by the extrafine formulation.

Background Although patients have more problems using metered dose inhalers, clinical comparisons suggest they provide similar control to dry powder inhalers. Using real-life situations this study was designed to evaluate asthma control in outpatients with moderate to severe persistent asthma and to compare efficacy of fixed combinations of inhaled corticosteroids (ICS) and long acting beta-agonists (LABA). Methods This real-life study had a cross-sectional design. Patients using fixed combinations of ICS and LABA had their asthma control and spirometry assessed during regular visits. Results 111 patients were analyzed: 53 (47.7%) received maintenance therapy of extrafine beclomethasone-formoterol (BDP/F) pressurized metered dose inhaler (pMDI), 25 (22.5%) fluticasone-salmeterol (FP/S) dry powder inhaler (DPI), and 33 (29.7%) budesonide-formoterol (BUD/F) DPI. Severity of asthma at time of diagnosis, assessed by the treating physician, was comparable among groups. Asthma control was achieved by 45.9% of patients; 38.7% were partially controlled and 15.3% were uncontrolled. In the extrafine BDF/F group, asthma control total score, daytime symptom score and rescue medication use score were significantly better than those using fixed DPI combinations (5.8 ± 6.2 vs. 8.5 ± 6.8; 1.4 ± 1.8 vs. 2.3 ± 2.1; 1.8 ± 2.2 vs. 2.6 ± 2.2; p = 0.0160; p = 0.012 and p = 0.025, respectively) and the mean daily ICS dose were significantly lower. Conclusions pMDI extrafine BDP/F combination demonstrated better asthma control compared to DPIs formulated with larger particles. This could be due to the improved lung deposition of the dose or less reliance on the optimal inhalation technique or both.
