    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 The aim of this study was to test the hypothesis that use of tiotropium , a new long-acting anticholinergic bronchodilator , would be associated with sustained reduction in lung hyperinflation and , thereby , would improve exertional dyspnoea and exercise performance in patients with chronic obstructive pulmonary disease . A r and omised , double-blind , placebo-controlled , parallel-group study was conducted in 187 patients ( forced expiratory volume in one second 44±13 % pred ) : 96 patients received 18 µg tiotropium and 91 patients received placebo once daily for 42 days . Spirometry , plethysmographic lung volumes , cycle exercise endurance and exertional dyspnoea intensity at 75 % of each patient 's maximal work capacity were compared . On day 42 , the use of tiotropium was associated with the following effects at pre-dose and post-dose measurements as compared to  placebo : vital capacity and inspiratory capacity ( IC ) increased , with inverse decreases in residual volume and functional residual capacity  . Tiotropium  increased post-dose exercise endurance time by 105±40 s ( 21 % ) as compared to placebo on day 42 . At a st and ardised time near end-exercise ( isotime ) , IC , tidal volume and minute ventilation all increased , whilst dyspnoea decreased by 0.9±0.3 Borg scale units . In conclusion , the use of tiotropium was associated with sustained reductions of lung hyperinflation at rest and during exercise . Result ant increases in inspiratory capacity permitted greater expansion of tidal volume and contributed to improvements in both exertional dyspnoea and exercise endurance INTRODUCTION Aclidinium bromide/formoterol fumarate ( AB/FF ) 400/12 μg efficacy and safety was demonstrated in two 6-month Phase III studies ( AUGMENT and ACLIFORM ) and a 12-month study in patients with moderate to severe chronic obstructive pulmonary disease ( COPD ) . This Phase III , double-blind , placebo-controlled , 6-month AUGMENT extension investigated the long-term safety and tolerability of AB/FF 400/12 μg ( NCT01572792 ) . METHODS Patients were r and omised in AUGMENT  ( 1:1:1:1:1 ) to twice-daily AB/FF 400/12 μg , AB/FF 400/6 μg , AB 400 μg , FF 12 μg or placebo . Patients completing AUGMENT were invited to continue the same treatment in the extension . Adverse events ( AEs ) , major adverse cardiovascular events ( MACE ) , laboratory tests , electrocardiograms and vital signs were recorded . Efficacy was assessed . RESULTS Of 1322 patients completing AUGMENT , 921 enrolled and 780 completed the extension .  AE incidence was low and comparable across treatment groups ; most common were nasopharyngitis ( range 4.8%-9.3 % ) , urinary tract infection ( range 4.1%-8.8 % ) and upper respiratory tract infection ( range 2.7%-5.5 % ) . Serious AEs ( SAEs ) and MACE were low ( ranges 6.8%-7.7 % and 0.5%-1.5 % , respectively ) . Significant improvements in bronchodilation and dyspnoea were maintained over 52 weeks versus placebo . Trends towards improvements in other symptoms and health status were observed versus placebo and monotherapies . AB/FF combinations increased the time to first exacerbation by approximately 30 % versus placebo ( p < 0.05 ) . CONCLUSION AB/FF 400/12 μg was well tolerated over 52 weeks with low incidences of AEs , SAEs and MACE that were comparable across treatment groups . Improvements in bronchodilation , symptoms and health status were maintained across 52 weeks Background Combining two long-acting bronchodilators with complementary mechanisms of action may provide treatment benefits to patients with chronic obstructive pulmonary disease ( COPD ) that are greater than those derived from either treatment alone . The efficacy and safety of a fixed-dose combination ( FDC ) of aclidinium bromide , a long-acting muscarinic antagonist , and formoterol fumarate , a long-acting β2-agonist , in patients with moderate to severe COPD are presented . Methods In this 24-week double-blind study , 1692 patients with stable COPD were equally r and omized to twice-daily treatment with FDC aclidinium 400μg/formoterol 12μg ( ACL400/FOR12 FDC ) , FDC aclidinium 400μg/formoterol 6μg ( ACL400/FOR6 FDC ) , aclidinium 400μg , formoterol 12μg , or placebo administered by a multidose dry powder inhaler (Genuair ® /Pressair ® )*. Co primary endpoints were change from baseline to week 24 in 1-hour morning postdose FEV1 ( FDCs versus aclidinium ) and change from baseline to week 24 in morning predose ( trough ) FEV1 ( FDCs versus formoterol ) . Secondary endpoints were change from baseline in St. George ’s Respiratory Question naire ( SGRQ ) total score and improvement in Transition Dyspnea Index ( TDI ) focal score at week 24 . Safety and tolerability were also assessed . Results At study end , improvements from baseline in 1-hour postdose FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC or ACL400/FOR6 FDC compared with aclidinium ( 108 mL and 87 mL , respectively ; p < 0.0001 ) . Improvements in trough FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC versus formoterol ( 45 mL ; p = 0.0102 ) , a numerical improvement of 26 mL in trough FEV1 over formoterol was observed with ACL400/FOR6 FDC . Significant improvements in both SGRQ total and TDI focal scores were observed in the ACL400/FOR12 FDC group at study end ( p < 0.0001 ) , with differences over placebo exceeding the minimal clinical ly important difference of ≥4 points and ≥1 unit , respectively . All treatments were well tolerated , with safety profiles of the FDCs similar to those of the monotherapies . Conclusions Treatment with twice-daily aclidinium 400μg/formoterol 12μg FDC provided rapid and sustained bronchodilation that was greater than either monotherapy ; clinical ly significant improvements in dyspnea and health status were evident compared with placebo . Aclidinium/formoterol FDC may be an effective and well tolerated new treatment option for patients with COPD .Trial registration Clinical trials.gov NCT01437397.*Registered trademarks of Almirall S.A. , Barcelona , Spain ; for use within the US as Pressair ® and Genuair ® within all other licensed territories BACKGROUND Combination long-acting bronchodilator treatment might be more effective than long-acting bronchodilator monotherapy for the treatment of chronic obstructive pulmonary disease ( COPD ) . We aim ed 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 . METHODS In two multicentre , r and omised , 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 r and omly 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 H and iHaler inhaler and all other active treatments were delivered via the ELLIPTA dry powder inhaler . R and om assignment ( by a vali date d 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 Clinical Trials.gov , numbers NCT01316900 ( study 1 ) and NCT01316913 ( study 2 ) . FINDINGS 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·
