Effect of NVA237 on Exercise Endurance in Patients With Chronic Obstructive Pulmonary Disease (COPD)

Study Overview
=================
Brief Summary
-----------------
The ability for patients with COPD to exercise is limited due to the deterioration of their lung function. NVA237 is being developed to treat COPD. This study is designed to look at how well NVA237 improves the ability to exercise in patients with moderate to severe COPD.

Patients whose exercise endurance time at sub-maximal workload was above 25 min at baseline Patients with a clinically significant abnormality on the screening or baseline ECG who in the judgment of the investigator would have been at potential risk if enrolled into the study Patients with a history of long QT syndrome or whose QTc was prolonged (> 450 ms for males and > 470 ms females) at screening (Fredericia's correction) Other protocol-defined inclusion/exclusion criteria applied

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Exercise Endurance Time During a Sub-maximal Constant-load Cycle Ergometry Test (SMETT) After 3 Weeks (Day 21) of Treatment | SMETT is an exercise procedure where the patient cycles at 80% of the maximum workload (Wmax )value achieved at the Incremental exercise test. During this test, the patient will cycle at a constant load. Exercise endurance time was from commencement of loaded pedaling to stopping exercise. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Isotime Inspiratory Capacity (IC) During Sub-maximal Constant-load Cycle Ergometry Test (SMETT) After 3 Weeks of Treatment | Isotime is the last matching timepoint in the submaximal exercise tolerance test (SMETT) at which for both periods the patient has a test result. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Inspiratory Capacity (IC) at Rest (1 Hour Post Dose) and at Peak (End of Exercise) During Sub-maximal Constant-load Cycle Ergometry Test (SMETT) After 3 Weeks of Treatment | IC at peak was observed using spirometry. However, two different methodologies (whole body plethysmography (Bodybox) and spirometry) were used to observe IC at rest. The analysis of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Peak and Trough (24 h Post Dose) Forced Expiratory Volume in 1 Second (FEV1) and Forced Vital Capacity (FVC) | FEV1 is the amount of air that can be exhaled in one second. FEV1 was measured with spirometry conducted according to internationally accepted standards. FVC is the volume of air that can forcibly be blown out after full inspiration and is used in spirometry tests. The trough effects of Day 1 treatment are derived from values prior to morning dosing on the next treatment day (Day 2 of the corresponding period). The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Slow Vital Capacity (SVC) and Total Lung Capacity (TLC) | Vital Capacity is the amount of air that can be forcibly exhaled from the lungs after a full inhalation. Slow Vital Capacity (SVC) test is performed by having the patient slowly and completely blow out all of the air from their lungs. Total Lung Capacity (TLC) is the best vital capacity plus residual volume. Whole body plethysmography (Bodybox) was used to measure SVC and TLC. The trough effects of Day 1 treatment are derived from values prior to morning dosing on the next treatment day (Day 2 of the corresponding period). | Day 21 | 
| Specific Airways Conductance (SGaw) | SGaw is a measure of how hard it is to get air into the lungs, measured by (Sec(-1)*kP). Whole body plethysmography (Bodybox) was used to measure SGaw. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Exertional Dyspnea (Borg CR10 Scale) During Sub-maximal Constant-load Cycle Ergometry Test (SMETT) After 3 Weeks Treatment | The Borg CR10 Scale consists of 12-point score that the patients pointed to so as to indicate their level of dyspnea before and during exercise testing (where 0 indicates no breathlessness at all and 12 indicates maximum breathlessness). A reduction in this score indicates an improvement. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Leg Discomfort (Borg CR10 Scale) During Sub-maximal Constant-load Cycle Ergometry Test (SMETT) After 3 Weeks Treatment | The modified Borg CR10 Scale consists of 12-point score that the patients pointed to so as to indicate their level of leg discomfort before and during exercise testing (where 0 indicates no breathlessness at all and 12 indicates maximum breathlessness). A reduction in this score indicates an improvement. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 21 | 
| Exercise Endurance Time During a Sub-maximal Constant-load Cycle Ergometry Test (SMETT) on Treatment Day 1 | SMETT is an exercise procedure where the patient cycles at 80% of the maximum workload (Wmax )value achieved at the Incremental exercise test. During this test, the patient will cycle at a constant load. Exercise endurance time was from commencement of loaded pedaling to stopping exercise. The analysis-of covariance model included the sequence, period, and treatment as fixed factors, the baseline value as covariate and the patient as a random effect. | Day 1 |
