Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~Patients with stable COPD according to the current GOLD guidelines (GOLD 2013). Current or ex-smokers who have a smoking history of at least 10 pack years (e.g. 10 pack years = 1 pack /day x 10 yrs, or ½ pack/day x 20 yrs)..~Patients with airflow limitation indicated by a post-bronchodilator FEV1 ≥40% and \<80% of the predicted normal, and a post-bronchodilator FEV1/FVC \<0.70~Exclusion Criteria:~Patients with conditions contraindicated for treatment with, or having a history of reactions/hypersensitivity to any of the following inhaled drugs, drugs of a similar class or any component thereof, anticholinergics, long and short acting beta2 agonists, sympathomimetic amines, lactose or any of the other excipients Patients who have a clinically significant ECG abnormality at Visit 1, who in the judgment of the investigator would be at potential risk if enrolled into the study.~Patients with paroxysmal (e.g. intermittent) atrial fibrillation are excluded. Patients with persistent atrial fibrillation as defined by continuous atrial fibrillation for at least 6 months and controlled with a rate control strategy (i.e., beta blocker, calcium channel blocker, pacemaker placement, digoxin or ablation therapy) for at least 6 months may be considered for inclusion. In such patients, atrial fibrillation must be present at baseline and screening visits, with a resting ventricular rate \< 100/min.~Patients with Type I or uncontrolled Type II diabetes and patients with a history of blood glucose levels consistently outside the normal range Patients with narrow-angle glaucoma, symptomatic prostatic hyperplasia or bladder-neck obstruction or moderate to severe renal impairment or urinary retention.~Patients with a history of malignancy of any organ system, treated or untreated, within the past 5 years whether or not there is evidence of local recurrence or metastases, with the exception of localized basal cell carcinoma of the skin. Patients with non-melanoma skin carcinoma may be considered for the study.~Patients with a body mass index (BMI) of more than 40 kg/m2. Women who are pregnant or breast feeding Patients requiring long term oxygen therapy on a daily basis for chronic hypoxemia.~Patients who have had a COPD exacerbation that required treatment with antibiotics and/or oral corticosteroids and/or hospitalization in the 6 weeks prior to screening.~Patients who have had a respiratory tract infection within 4 weeks prior to screening.~Patients with any history of asthma. Patients with concomitant pulmonary disease Patients with clinically significant bronchiectasis. Other protocol-defined inclusion/exclusion criteria may apply
