Efficacy, Safety and Tolerability of the Co-administration of NVA237 Plus Indacaterol Once Daily Versus Indacaterol Once Daily in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD) (GLOW6)

• Post dose treatment comparison of forced expiratory volume in 1 second / Area Under the Curve between 5 min and 4 hours [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Centralized spirometry according to internationally accepted standards. The trapezoidal rule will be used to calculate forced expiratory volume in 1 second (FEV1) Area Under the Curve (AUC). Whether the participants have complete or incomplete FEV1 assessments in respective time ranges, their AUCs will be calculated based on the existing FEV1 measurements. Specifically, for those patients who have FEV1 assessment at only one time-point, their AUC will be approximated by the observed FEV1.
• Treatment comparison of peak forced expiratory volume in 1 second [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  Centralized spirometry according to internationally accepted standards. Peak forced expiratory volume in 1 second (FEV1) is defined as the maximum FEV1 during the first 4 hours post morning dosing. The mixed model will contain treatment as a fixed effect with the baseline measurement of trough FEV1, FEV1 prior to inhalation of short acting bronchodilator and FEV1 post inhalation of short acting bronchodilator as covariates.
• Treatment comparison of forced expiratory volume in 1 second at individual time-points [ Time Frame: Day 1, Day 29, Day 57 and Days 84/85 ] [ Designated as safety issue: No ]
  Centralized spirometry according to internationally accepted standards. Forced expiratory volume in 1 second (FEV1) is measured at all post-dose time points up to 4 hours, and at 23 hours 15 minutes and 23 hours 45 minutes, by visit. Mixed model uses baseline FEV1, baseline inhaled corticosteroid use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.
• Treatment comparison of forced vital capacity (FVC) at individual time-points [ Time Frame: Day 1, Day 29, Day 57 and Days 84/85 ] [ Designated as safety issue: No ]
  Forced Vital Capacity (FVC) is calculated at each time point up to 4 hours post-dose and at 23 hours 15 minutes and 23 hours 45 minutes, by visit. Mixed model uses baseline FVC, baseline inhaled corticosteroid use, forced expiratory volume in 1 second (FEV1) prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.
• Treatment comparison of Inspiratory Capacity (IC) at individual time-points [ Time Frame: Day 1, Day 29, Day 57 and Days 84/85 ] [ Designated as safety issue: No ]
  Inspiratory Capacity (IC) is measured at 20 minutes pre-dose and post-dose at 25 minutes, 1 hour 55 minutes, 3 hours 55 minutes and 23 hours 40 minutes, by visit. Mixed model uses baseline IC, baseline inhaled corticosteroid use, forced expiratory volume in 1 second (FEV1) prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 min post-inhalation of SABA as covariates.
• Treatment comparison of mean change from baseline in daily number of puffs of rescue medication [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
  The number of puffs of rescue medication taken in the previous 12 hours will be recorded in the patient diary in the morning and evening. The total number of puffs of rescue medication per day over the whole active treatment period will be calculated and divided by the total number of days with non-missing rescue data to derive the mean daily number of puffs of rescue medication taken for the patient.
• Treatment comparison of Focal score of the Transitional Dyspnea Index (TDI) [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
  Measured at baseline using the Baseline Dyspnea Index (BDI) and during treatment using the Transitional Dyspnea Index (TDI). Analysis will be done via mixed model. BDI domains rated from 0 (severe) to 4 (unimpaired) and rates summed for baseline focal score ranging from 0 to 12; lower scores mean worse severity. TDI domains are rated from -3 (major deterioration) to 3 (major improvement) and rates summed for transition focal score ranging from -9 to 9; negative scores indicate deterioration. A TDI focal score of 1considered the minimal clinically important difference from baseline.
• Treatment comparison throughout treatment period of symptoms via patient electronic diary [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  The symptoms (respiratory, cough, wheeze, sputum color, sputum production, breathlessness, sore throat, nasal discharge or congestion, and fever) for the whole active treatment period will be analyzed using mixed model, with the baseline forced expiratory volume in 1 second (FEV1) term being replaced by the respective baseline symptoms.
• Adverse Events and Serious Adverse Events [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  All study emergent adverse events including Chronic Obstructive Pulmonary Disease exacerbations will be summarized and listed.

This study will assess the efficacy, safety and tolerability of the co-administration of NVA237 plus indacaterol taken once daily versus indacaterol taken once daily in patients with moderate to severe Chronic Obstructive Pulmonary Disease.
