A Study to Assess the Safety, Tolerability and Efficacy of NVA237 Versus Placebo

Transition Dyspnea Index (TDI) captures changes from baseline. The TDI score is based on three domains with each domain scored from -3 (major deterioration) to +3 (major improvement), to give an overall score of -9 to +9, a negative score indicating a deterioration from baseline. A TDI focal score of 1 is considered to be a clinically significant improvement from baseline. Mixed model used baseline TDI, baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

SGRQ is a health related quality of life questionnaire consisting of 51 items in three components: symptoms, activity, and impacts. The lowest possible value is zero and the highest 100. Higher values correspond to greater impairment in quality of life. Mixed model used baseline SGRQ, baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

The time to the first moderate or severe COPD exacerbation was the study day on which the patient experienced first moderate or severe COPD exacerbation. COPD exacerbations are considered to be moderate if treatment with systemic corticosteroids and/or antibiotics was required. COPD exacerbations are considered to be severe if treatment for moderate severity and hospitalization were required.

Participants recorded the number of puffs of rescue medication taken in the previous 12 hours in the morning and evening. The total number of puffs of rescue medication per day over the full 26 weeks was calculated and divided by the total number of days with non-missing rescue medication data to derive the mean daily number of puffs of rescue medication taken for the patient.

Spirometry was conducted according to internationally accepted standards. FEV1 was measured at all time points up to 4 hours post-dose, and at 23 hours 15 min and 23 hours 45 min, by visit. Mixed model used baseline FEV1,baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

Spirometry was conducted according to internationally accepted standards. FVC was calculated at each time point up to 4 hours post-dose and at 23 hours 15 min and 23 hours 45 min, by visit. Mixed model used baseline FVC, baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

The standardized (with respect to the length of time) area under the curve (AUC) for FEV1 was calculated using trapezoidal rule between 5 min and 12 h post dose at Week 1 Day 1, Week 12 and Week 26 for every patient in the serial spirometry subgroup. Mixed model used baseline FEV1,baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

The standardized (with respect to the length of time) area under the curve (AUC) for FEV1 was calculated using trapezoidal rule between 5 min and 23 h 45 min post dose at week12/week 13and week 26/week 27 where available for every patient in the serial spirometry subgroup. Mixed model used baseline FEV1,baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.

Spirometry was conducted according to internationally accepted standards. Trough FEV1 was defined as the average of the 23 hour 15 minute and 23 hour 45 minute post-dose FEV1 readings. Mixed model used baseline FEV1, baseline ICS use, FEV1 prior to inhalation of SABA, and FEV1 45 minutes post-inhalation of SABA as covariates.

Trough FVC was defined as the average of the 23 hour 15 minute and 23 hour 45 minute post-dose FVC readings. Mixed model used baseline FVC, baseline ICS use, FEV1 prior to inhalation of SABA, and FEV1 45 minutes post-inhalation of SABA as covariates.

The mean heart rate was collected with a 24 hour Holter monitor in a sub-set of the safety population. The change between baseline and day 1, week 12 and week 26 was calculated. The analysis of the Holter recordings was performed by a central facility. Data on heart rate, heart rate variability, supraventricular and ventricular ectopy were collected and assessed.

Adverse events are defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards.

One overall rate is calculated for the entire study population. Rate is the number of moderate or severe exacerbations per year = total number of moderate or severe exacerbations for all participants/total number of treatment years for all participants. COPD exacerbations were considered to be moderate if treatment with systemic corticosteroids and/or antibiotics was required. COPD exacerbations were considered to be severe if treatment for moderate severity and hospitalization were required.

The percentage of nights with no nighttime awakenings is defined as the total number of nights with no nighttime awakenings over the 26 week treatment period divided by the total number of night where diary recordings have been made.

Mixed model used baseline nighttime awakenings, baseline ICS use, FEV1 prior to inhalation of SABA, and FEV1 45 minutes post-inhalation of SABA as covariates.

The percentage of days with no daytime symptoms is defined as the total number of days with no daytime symptoms over the 26 week treatment period divided by the total number of days where diary recordings have been made.

Mixed model used baseline daytime symptoms, baseline ICS use, FEV1 prior to inhalation of SABA, and FEV1 45 minutes post-inhalation of SABA as covariates.

The percentage of days able to perform usual daily activities is defined as the total number of days able to perform usual activities over the 26 week treatment period divided by the total number of days where diary recordings have been made.

Mixed model used baseline ability to perform usual daily activities, baseline ICS use, FEV1 prior to inhalation of SABA, and FEV1 45 minutes post-inhalation of SABA as covariates.

The daily symptom score was calculated as the sum of the worst of the morning and evening assessments for each symptom (symptoms, cough, wheeze, sputum color/production, and breathlessness). The score can range from 0 to 18 with 0 indicating no symptoms. The higher the score, the worse the symptomatic status. A negative change (lower number) indicates improvement.

Mixed model used baseline symptom variables, baseline inhaled corticosteroid (ICS) use, FEV1 prior to inhalation of short acting beta-agonist (SABA), and FEV1 45 minutes post-inhalation of SABA as covariates.
