          Abstract

          The use of inhaled, fixed-dose, long-acting muscarinic antagonists (LAMA) combined with long-acting, beta 2-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.

          Chronic obstructive pulmonary disease

           Marc DeCramer,  Wim Janssens,  Marc Miravitlles (2012)
          Summary Chronic obstructive pulmonary disease (COPD) is characterised by progressive airflow obstruction that is only partly reversible, inflammation in the airways, and systemic effects or comorbities. The main cause is smoking tobacco, but other factors have been identified. Several pathobiological processes interact on a complex background of genetic determinants, lung growth, and environmental stimuli. The disease is further aggravated by exacerbations, particularly in patients with severe disease, up to 78% of which are due to bacterial infections, viral infections, or both. Comorbidities include ischaemic heart disease, diabetes, and lung cancer. Bronchodilators constitute the mainstay of treatment: β2 agonists and long-acting anticholinergic agents are frequently used (the former often with inhaled corticosteroids). Besides improving symptoms, these treatments are also thought to lead to some degree of disease modification. Future research should be directed towards the development of agents that notably affect the course of disease.

            Device selection and outcomes of aerosol therapy: Evidence-based guidelines: American College of Chest Physicians/American College of Asthma, Allergy, and Immunology.

             Trevor P. Anderson,  R C Ahrens,  Gordon Guyatt … (2004)
            The proliferation of inhaler devices has resulted in a confusing number of choices for clinicians who are selecting a delivery device for aerosol therapy. There are advantages and disadvantages associated with each device category. Evidence-based guidelines for the selection of the appropriate aerosol delivery device in specific clinical settings are needed. (1) To compare the efficacy and adverse effects of treatment using nebulizers vs pressurized metered-dose inhalers (MDIs) with or without a spacer/holding chamber vs dry powder inhalers (DPIs) as delivery systems for beta-agonists, anticholinergic agents, and corticosteroids for several commonly encountered clinical settings and patient populations, and (2) to provide recommendations to clinicians to aid them in selecting a particular aerosol delivery device for their patients. A systematic review of pertinent randomized, controlled clinical trials (RCTs) was undertaken using MEDLINE, EmBase, and the Cochrane Library databases. A broad search strategy was chosen, combining terms related to aerosol devices or drugs with the diseases of interest in various patient groups and clinical settings. Only RCTs in which the same drug was administered with different devices were included. RCTs (394 trials) assessing inhaled corticosteroid, beta2-agonist, and anticholinergic agents delivered by an MDI, an MDI with a spacer/holding chamber, a nebulizer, or a DPI were identified for the years 1982 to 2001. A total of 254 outcomes were tabulated. Of the 131 studies that met the eligibility criteria, only 59 (primarily those that tested beta2-agonists) proved to have useable data. None of the pooled metaanalyses showed a significant difference between devices in any efficacy outcome in any patient group for each of the clinical settings that was investigated. The adverse effects that were reported were minimal and were related to the increased drug dose that was delivered. Each of the delivery devices provided similar outcomes in patients using the correct technique for inhalation. Devices used for the delivery of bronchodilators and steroids can be equally efficacious. When selecting an aerosol delivery device for patients with asthma and COPD, the following should be considered: device/drug availability; clinical setting; patient age and the ability to use the selected device correctly; device use with multiple medications; cost and reimbursement; drug administration time; convenience in both outpatient and inpatient settings; and physician and patient preference.

              Efficacy and safety of umeclidinium plus vilanterol versus tiotropium, vilanterol, or umeclidinium monotherapies over 24 weeks in patients with chronic obstructive pulmonary disease: results from two multicentre, blinded, randomised controlled trials.

               Stephanie Harris,  Marc Decramer,  Alison Church … (2014)
              Combination long-acting bronchodilator treatment might be more effective than long-acting bronchodilator monotherapy for the treatment of chronic obstructive pulmonary disease (COPD). We aimed to compare the efficacy and safety of umeclidinium (UMEC) plus vilanterol (VI) with tiotropium (TIO) monotherapy, UMEC monotherapy, or VI monotherapy in patients with moderate to very severe COPD. In two multicentre, randomised, blinded, double-dummy, parallel-group, active-controlled trials, eligible patients (current or former smokers aged 40 years or older with an established clinical history of COPD) were randomly assigned in 1:1:1:1 ratio to UMEC 125 μg plus VI 25 μg, UMEC 62·5 μg plus VI 25 μg, TIO 18 μg, and either VI 25 μg (study 1) or UMEC 125 μg (study 2). All study drugs were used once daily for 24 weeks. TIO was delivered via the HandiHaler inhaler and all other active treatments were delivered via the ELLIPTA dry powder inhaler. Random assignment (by a validated computer-based system) was done by centre and was not stratified. All patients and physicians were masked to assigned treatment during the studies. The primary efficacy endpoint of both studies was trough forced expiratory volume in 1 s (FEV1) on day 169, which was analysed in the intention-to-treat population. Both studies are registered with ClinicalTrials.gov, numbers NCT01316900 (study 1) and NCT01316913 (study 2). 1141 participants were recruited in study 1, and 1191 in study 2. For study 1, after exclusions, 208, 209, 214, and 212 patients were included in the intention-to-treat analyses for TIO monotherapy, VI monotherapy, UMEC 125 μg plus VI 25 μg, and UMEC 62·5 μg plus VI 25 μg, respectively. For study 2, 215, 222, 215, and 217 patients were included in the intention-to-treat analyses for TIO monotherapy, UMEC monotherapy, UMEC 125 μg plus VI 25 μg, and UMEC 62·5 μg plus VI 25 μg, respectively. In both studies, we noted improvements in trough FEV1 on day 169 for both doses of UMEC plus VI compared with TIO monotherapy (study 1, UMEC 125 μg plus VI 25 μg: 0·088 L [95% CI 0·036 to 0·140; p=0·0010]; study 1, UMEC 62·5 μg plus VI 25 μg: 0·090 L [0·039 to 0·141; p=0·0006]; study 2, UMEC 125 μg plus VI 25 μg: 0·074 L [0·025 to 0·123; p=0·0031]; study 2, UMEC 62·5 μg plus VI 25 μg: 0·060 L [0·010 to 0·109; nominal p=0·0182]). Both doses of UMEC plus VI also improved trough FEV1 compared with VI monotherapy (UMEC 125 μg plus VI 25 μg: 0·088 L [0·036 to 0·140; p=0·0010]; UMEC 62·5 μg plus VI 25 μg: 0·090 L [0·039 to 0·142; p=0·0006], but not compared with UMEC 125 μg monotherapy (UMEC 125 μg plus VI 25 μg: 0·037 L [-0·012 to 0·087; p=0·14]; UMEC 62·5 μg plus VI 25 μg: 0·022 L [-0·027 to 0·072; p=0·38]). All treatments produced improvements in dyspnoea and health-related quality of life; we noted no significant differences in symptoms, health status, or risk of exacerbation between UMEC plus VI and TIO. The most common on-treatment, severe-intensity adverse event in both studies was acute exacerbation of COPD (1-4 [<1-2%] patients across treatment groups in study 1 and 1-6 [<1-3%] patients in study 2). We recorded five to 15 (2-7%) on-treatment serious adverse events across treatment groups in study 1, and nine to 22 (4-10%) in study 2. We noted no substantial changes from baseline in vital signs, clinical laboratory findings, or electrocardiography findings in any of the treatment groups. Combination treatment with once-daily UMEC plus VI improved lung function compared with VI monotherapy and TIO monotherapy in patients with COPD. Overall our results suggest that the combination of UMEC plus VI could be beneficial for the treatment of moderate to very severe COPD. GlaxoSmithKline. Copyright © 2014 Elsevier Ltd.
