Title: N/A
Brief Summary: The main purpose of this study is to evaluate the efficacy, safety and tolerability of multiple doses of inhaled aclidinium bromide in moderate to severe COPD patients.


Options:
A: Criteria

* Patients with stable moderate to severe COPD and a smoking history of at least 10 pack years were eligible for inclusion in the study. Patients with significant diseases other than COPD were excluded as were patients with a recent history of myocardial infarction, history of malignancy, unstable or life-threatening cardiac arrhythmia, narrow-angle glaucoma, asthma or other allergic conditions. Patients treated with cromolyn, nedocromil, oral beta-adrenergics or unstable doses of oral corticosteroids were ineligible for inclusion in the study as were patients who had received previous treatment with tiotropium.
B: Inclusion Criteria:

* Adult male and female patients aged 40 with stable moderate to severe COPD (GOLD guidelines).
* Post-salbutamol (FEV1) \< 80% and ≥ 30% of predicted normal value and Post-salbutamol FEV1/FVC \< 70%.
* Current or ex smokers of 10 pack-years.

Exclusion Criteria:

* Patients with no history or current diagnosis of asthma.
* No evidence of an exacerbation within 6 weeks prior to the screening visit.
* No evidence of clinically significant respiratory and/or cardiovascular conditions or laboratory abnormalities.
* No contraindication to use of anticholinergic drugs such as known symptomatic prostatic hypertrophy, bladder neck obstruction or narrow-angle glaucoma.
C: Inclusion Criteria:

* Written informed consent.
* Male or female patients 40 years of age or older.
* Smoking history of at least 10 pack years.
* Diagnosis of COPD with post bronchodilator FEV1 less than or equal to 70% of predicted normal and FEV1\<70% of FVC and on stable respiratory medication.

Exclusion Criteria:

* Significant diseases other than COPD which in the opinion of the investigator may put the patient at risk or influence the patients ability to participate.
* Myocardial infarction in past 6 months.
* Unstable or life threatening arrhythmia in past year.
* Hospitalization for NYHA heart failure class III or IV in past year.
* Active tuberculosis.
* Asthma.
* Pulmonary resection.
* Malignancy treated with radiation or chemotherapy in past 5 years.
* Respiratory infection in 4 weeks prior to screening.
* Known hypersensitivity to anticholinergic drugs or components.
* Known moderate to severe renal impairment.
* Known narrow angle glaucoma.
* Significant symptomatic BPH or bladder neck obstruction.
* Need for oxygen therapy \>12 hr/day.
* Use of oral corticosteroids at unstable doses or \>10 mg/day.
D: Inclusion criteria:

All subjects must have a diagnosis of Chronic Obstructive Pulmonary Disease (COPD) according to Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) guideline criteria:

post-bronchodilator Forced Expiratory Volume in one Second/Forced Vital Capacity (FEV1/FVC) ratio \< 70% (visit 1).

Subjects must be GOLD Stage II and have a post-bronchodilator FEV1 \>50% and \< 80% of predicted normal (visit 1). Subjects must be current or ex-smokers with a smoking history of \>=10 pack years.

Subjects must have a Medical Research Council (MRC) dyspnea score \>= 2.

Exclusion criteria:

Subjects who have been treated with maintenance medications for chronic respiratory disease within six months prior to screening.

Subjects with significant diseases other than COPD. Subjects on chronic systemic corticosteroids.

Subjects with any upper and/or lower respiratory tract infection or COPD exacerbation in the 6 weeks prior to the initial visit 1 or during the screening period prior to visit 3 Subjects with a recent (past 6 months) myocardial infarction, any unstable or life threatening cardiac arrhythmia requiring intervention or change in drug therapy during the last year; or who have been hospitalized for cardiac failure during the past year.
