Exclusion Criteria:

1. Pregnancy, nursing, or plans to become pregnant or donate gametes (ova or sperm) for in vitro fertilization during the study period or for 30 days following the subject's last study related visit (for eligible subjects only, if applicable).

2. History or current evidence (as determined by medical history, physical examination, clinical laboratory assessments and ECG) of a clinically significant or uncontrolled disease including, but not limited to: cardiovascular (e.g., uncontrolled hypertension, congestive heart failure, known aortic aneurysm, clinically significant cardiac arrhythmia or coronary heart disease), hepatic, renal, haematological, neuropsychological, endocrine (e.g., uncontrolled diabetes mellitus, uncontrolled thyroid disorder, Addison's disease, Cushing's syndrome), gastrointestinal (e.g., poorly controlled peptic ulcer, gastroesophageal reflux disease) or pulmonary (other than COPD such as asthma, sarcoidosis, non-cystic fibrosis (CF) bronchiectasis, cystic fibrosis, bronchopulmonary dysplasia or a diagnosis of alpha 1-antitrypsin deficiency). Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which could affect the endpoint analysis if the disease/condition exacerbated during the study.

3. History of and/or current diagnosis of asthma

4. History of a life-threatening COPD exacerbation - defined for this protocol as a COPD episode that required intubation and/or was associated with hypercapnia, respiratory arrest or hypoxic seizures

5. Thoracotomy with pulmonary resection

6. Current congestive heart failure, history or current evidence of myocardial infarction (within 3 yrs of the Screening Visit [SV]), or history or current evidence of ischemic heart disease, including a diagnosis on screening ECG.

7. History or current evidence of clinically significant cardiac arrhythmia, including a diagnosis on screening ECG.

8. Presence of angle-closure glaucoma

9. History of malignancy (excluding basal cell carcinoma) within the past 5 years, regardless of the clinical significance or current stability of the disease

10. Known history or any current evidence of renal impairment or urinary retention (e.g., bladder outlet obstruction). This includes abnormal renal function test results at screening.

Note: An exacerbation of COPD is defined as any worsening of the subject's baseline COPD symptoms requiring any treatment other than rescue albuterol/salbutamol/ipratropium or the subject's regular maintenance treatment. This includes requiring the use of systemic corticosteroids and/or emergency room visit or hospitalization, a change in subject's regular, or the addition of other medications used to treat COPD symptoms.

25. Initiation or change in dose of inhaled corticosteroids within the last 6 weeks prior to the Screening Visit (SV), and /or not expected to maintain a stable dose of inhaled corticosteroids during the course of the study.
