        pregnancy test at Visit 1/Visit 1A, and agrees to one of the protocol-specified acceptable
        contraceptive methods used consistently and correctly (i.e. according to the approved
        product label and the instructions of the physician for the duration of the study -

             pack-years 1.

          -  A post-albuterol/salbutamol FEV1/FVC ratio of ≤0.70 and a post-albuterol/salbutamol
             FEV1 of ≥35 and ≤70% of predicted normal values

        Exclusion Criteria:

        Subjects meeting any of the following criteria must not be enrolled in the study:

          -  Women who are pregnant or lactating.

          -  A current diagnosis of asthma.

          -  Known respiratory disorders other than COPD including but not limited to α-1
             antitrypsin deficiency as the underlying cause of COPD, active tuberculosis, lung
             cancer, bronchiectasis, sarcoidosis, lung fibrosis, pulmonary hypertension, and
             interstitial lung disease.

          -  Any previous lung resection surgery (e.g., lung volume reduction surgery or lobectomy)

          -  Clinically significant Chest X-ray or computed tomography (CT) scan abnormalities
             within 6 months prior to Visit 1 that are not believed to be due to COPD.

          -  Use of oral corticosteroids or antibiotics for COPD within 6 weeks prior to Visit 1.

          -  Hospitalization for COPD or pneumonia within 3 months prior to Visit 1.

          -  Medical diagnosis of narrow-angle glaucoma, prostatic hypertrophy or bladder neck
             obstruction that in the opinion of the study investigator would prevent use of an
             inhaled anticholingeric.

          -  Medically unable to withhold albuterol/salbutamol for 6 hours prior to spirometry
             testing at each study visit or to withhold ipratropium (if applicable) for the 6-hour

             propionate or equivalent within 30 days prior to Visit 1.

          -  Use of long-term oxygen therapy (LTOT) or supplemental oxygen required for greater
             than 12 hours a day. Oxygen use as needed is not exclusionary.

             prior to Visit 1.

          -  An investigator, sub-investigator, study coordinator, employee of a participating
             investigator or study site, or immediate family member of the above who is involved in

             abuse in the two years prior to Visit 1 (including drug and alcohol), or other
