    Input: We investigated the efficacy and safety of dual bronchodilation with QVA149 versus its monocomponents indacaterol and glycopyrronium , tiotropium and placebo in patients with moderate-to-severe chronic obstructive pulmonary disease ( COPD ) . This was a multicentre , r and omised , double-blind , placebo- and active-controlled , 26-week trial . Patients ( n = 2144 ) were r and omised ( 2:2:2:2:1 ) to receive once-daily QVA149 ( indacaterol 110 & mgr;g/glycopyrronium 50 & mgr;g ) , indacaterol 150 & mgr;g , glycopyrronium 50 & mgr;g , open-label tiotropium 18 & mgr;g or placebo . The primary end-point was trough forced expiratory volume in 1 s ( FEV1 ) at week 26 for QVA149 versus its monocomponents . Secondary end-points included dyspnoea , health status , rescue medication use and safety . Trough FEV1 at week 26 was significantly improved ( p<0.001 ) with QVA149 compared with indacaterol and glycopyrronium ( least squares mean ( LSM ) differences 0.07 L and 0.09 L , respectively ) , tiotropium and placebo ( LSM differences 0.08 L and 0.20 L , respectively ) ; these beneficial effects were sustained throughout the 26-week study . QVA149 significantly improved dyspnoea and health status versus placebo ( p<0.001 and p = 0.002 , respectively ) and tiotropium ( p = 0.007 and p = 0.009 , respectively ) at week 26 . All treatments were well tolerated . Dual bronchodilation with once-daily QVA149 demonstrated superior and clinical ly meaningful outcomes versus placebo and superiority versus treatment with a single bronchodilator , with a safety and tolerability profile similar to placebo , supporting the concept of fixed-dose long-acting muscarinic antagonist/long-acting & bgr;2-agonist combinations for the treatment of COPD . Dual indacaterol/glycopyrronium therapy was safe and more efficacious than monotherapy in moderate-to-severe COPD NVA237 ( glycopyrronium bromide ) is a once-daily long-acting muscarinic antagonist ( LAMA ) in development for chronic obstructive pulmonary disease ( COPD ) . The GLycopyrronium bromide in COPD airWays clinical Study 2 ( GLOW2 ) evaluated the efficacy and safety of NVA237 in moderate-to-severe COPD over 52 weeks . Patients were r and omised 2:1:1 to NVA237 50 μg , placebo or open-label tiotropium 18 μg for 52 weeks . Primary end-point was trough forced expiratory volume in 1 s ( FEV1 ) at 12 weeks . 1,066 patients were r and omised , 810 completed the study . At week 12 , trough FEV1 increased significantly by 97 mL with NVA237 ( 95 % CI 64.6–130.2 ; p<0.001 ) and 83 mL with tiotropium ( 95 % CI 45.6–121.4 ; p<0.001 ) . Compared with placebo , NVA237 produced significant improvements in dyspnoea ( Transition Dyspnoea Index at week 26 ; p=0.002 ) and health status ( St George 's Respiratory Question naire at week 52 ; p<0.001 ) . NVA237 significantly reduced the risk of moderate-to-severe COPD exacerbations by 34 % ( p=0.001 ) and the use of rescue medication ( p=0.039 ) , versus  placebo  . NVA237-placebo and tiotropium-placebo differences were comparable for all outcomes . Safety profiles were similar across groups . NVA237 50 μg provided significant improvements in lung function , dyspnoea , health status , exacerbations and rescue medication use , versus placebo , and was comparable to tiotropium . NVA237 can potentially be an alternative choice of LAMA for COPD patients Background NVA237 is a once-daily dry-powder formulation of the long-acting muscarinic antagonist glycopyrronium bromide in development for the treatment of chronic obstructive pulmonary disease ( COPD ) . The glycopyrronium bromide in COPD airways clinical study 1 ( GLOW1 ) evaluated the efficacy , safety and tolerability of NVA237 in patients with moderate-to-severe COPD . Methods Patients with COPD with a smoking history of ≥ 10 pack-years , post-bronchodilator forced expiratory volume in 1 second ( FEV1 ) < 80 % and ≥ 30 % predicted normal and FEV1/forced vital capacity < 0.70 were enrolled . Patients were r and omized to double-blind treatment with NVA237 50 μg once daily or placebo for 26 weeks with inhaled/intranasal corticosteroids or H1 antagonists permitted in patients stabilized on them prior to study entry . The primary outcome measure was trough FEV1 at Week 12 . Results A total of 822 patients were r and omized to NVA237 ( n = 552 ) or placebo ( n = 270 ) . Least squares mean ( ± st and ard error ) trough FEV1 at Week 12 was significantly higher in patients receiving NVA237 ( 1.408 ± 0.0105 L ) , versus placebo ( 1.301 ± 0.0137 L ; treatment difference 108 ± 14.8 mL , p < 0.001 ) . Significant improvements in trough FEV1 were apparent at the end of Day 1 and sustained through Week 26 . FEV1 was significantly improved in the NVA237 group versus placebo throughout the 24-hour periods on Day 1 and at Weeks 12 and 26 , and at all other visits and timepoints . Transition dyspnoea index focal scores and St. George 's Respiratory Question naire scores were significantly improved with NVA237 versus placebo at Week 26 , with treatment differences of 1.04 ( p < 0.001 ) and -2.81 ( p = 0.004 ) , respectively  . NVA237 significantly reduced the risk of first moderate/severe COPD exacerbation by 31 % ( p = 0.023 ) and use of rescue medication by 0.46 puffs per day ( p = 0.005 ) , versus placebo . NVA237 was well tolerated and had an acceptable safety profile , with a low frequency of cardiac and typical antimuscarinic adverse effects . Conclusions Once-daily NVA237 was safe and well tolerated and provided rapid , sustained improvements in lung function , improvements in dyspnoea , and health-related quality of life , and reduced the risk of exacerbations and the use of rescue medication . Trial registration Clinical Trials.gov : BACKGROUND Previous studies showing that tiotropium improves multiple end points in patients with chronic obstructive pulmonary disease ( COPD ) led us to examine the long-term effects of tiotropium therapy . METHODS In this r and omized , double-blind trial , we compared 4 years of therapy with either tiotropium or placebo in patients with COPD who were permitted to use all respiratory medications except inhaled anticholinergic drugs . The patients were at least 40 years of age , with a forced expiratory volume in 1 second ( FEV(1 ) ) of 70 % or less after bronchodilation and a ratio of FEV(1 ) to forced vital capacity ( FVC ) of 70 % or less . Co primary end points were the rate of decline in the mean FEV(1 ) before and after bronchodilation beginning on day 30 . Secondary end points included measures of FVC , changes in response on St. George 's Respiratory Question naire ( SGRQ ) , exacerbations of COPD , and mortality . RESULTS Of a total of 5993 patients ( mean age , 65+/-8 years ) with a mean FEV(1 ) of 1.32+/-0.44 liters after bronchodilation ( 48 % of predicted value ) , we r and omly assigned 2987 to the tiotropium group and 3006 to the placebo group . Mean absolute improvements in FEV(1 ) in the tiotropium group were maintained throughout the trial ( ranging from 87 to 103 ml before bronchodilation and from 47 to 65 ml after bronchodilation ) , as compared with the placebo group ( P<0.001 ) . After day 30 , the differences between the two groups in the rate of decline in the mean FEV(1 ) before and after bronchodilation were not significant . The mean absolute total score on the SGRQ was improved ( lower ) in the tiotropium group , as compared with the placebo group , at each time point throughout the 4-year period ( ranging from 2.3 to 3.3 units , P<0.001 ) . At 4 years and 30 days , tiotropium was associated with a reduction in the risks of exacerbations , related hospitalizations , and respiratory failure . CONCLUSIONS In patients with COPD , therapy with tiotropium was associated with improvements in lung function , quality of life , and exacerbations during a 4-year period but did not significantly reduce the rate of decline in FEV(1 ) .

Abstract Background : This Phase III study evaluated the efficacy and safety of twice-daily aclidinium 200 μg and 400 μg versus placebo in the treatment of moderate-to-severe COPD . Methods : In this 12-week , double-blind , multicenter trial , patients were r and omized ( 1:1:1 ) to inhaled twice-daily aclidinium 200 μg , aclidinium 400 μg , or placebo . Primary and secondary endpoints were changes from baseline in trough FEV1 and peak FEV1 at Week 12 , respectively . Health status ( St. George 's Respiratory Question naire [ SGRQ ] ) , COPD symptoms ( Transitional Dyspnea Index [ TDI ] , night and early morning symptoms ) , and safety were also assessed . Results : A total of 561 patients ( mean age , 64 ± 9 years ) with a mean baseline FEV1 of 1.36 ± 0.54 L ( 47.2 % of predicted value ) were r and omized . At Week 12 , aclidinium 200 μg and 400 μg showed significant improvements from baseline in mean ( 95 % CI ) trough FEV1 compared with placebo by 86 ( 45 , 127 ) mL and 124 ( 83,164 ) mL , respectively , and in peak FEV1 by 146 ( 101 , 190 ) mL and 192 ( 148 , 236 ) mL , respectively ( p ≤ 0.0001 for all ) . Both aclidinium doses also provided significant improvements in SGRQ , TDI and almost all COPD symptom scores compared with placebo ( p < 0.05 for all ) . Incidences of adverse events ( AEs ) were similar across treatment groups . The incidence of anticholinergic AEs was low and similar across groups ( dry mouth : 0.5%–1.6 % ; constipation : 0%-1.1 % ) . Conclusions : Treatment of moderate-to-severe COPD patients with twice-daily aclidinium 200 μg and 400 μg was associated with significant improvements in bronchodilation , health status , and COPD symptoms . Both doses were well tolerated and had safety profiles similar to placebo . Trial Registration : This ACCORD I study ( AClidinium in Chronic Obstructive Respiratory Disease I ) was registered on clinical trials.gov ( NCT00891462 ) as “ Efficacy and Safety of Aclidinium Bromide for Treatment of Moderate to Severe Chronic Obstructive Pulmonary Disease ( COPD ) ” The efficacy and safety of two doses of aclidinium bromide were evaluated in patients with moderate to severe chronic obstructive pulmonary disease ( COPD ) . In this 24-week , double-blind trial , patients were r and omised to twice-daily aclidinium ( 200 μg or 400 μg ) or placebo . The primary efficacy end-point was change in trough forced expiratory volume in 1 s ( FEV1 ) at week 24 . Other end-points included peak FEV1 , health status ( St George 's Respiratory Question naire ; SGRQ ) and dyspnoea ( Transitional Dyspnoea Index ; TDI ) . Overall , 828 patients were r and omised . At week 24 , significant improvements from baseline were observed with aclidinium 200 μg and 400 μg versus placebo for trough FEV1 ( 99 and 128 mL ; both p<0.0001 ) and peak FEV1 ( 185 and 209 mL ; both p<0.0
