         18. Patients with a clinically significant abnormality on the screening or baseline ECG
             who in the judgment of the investigator would be at potential risk if enrolled into
             the study. (These patients could not be re-screened).

         19. Patients who needed treatments for COPD and allied conditions after the start of the
             study (visit 1)

         20. Patients who needed treatments for COPD and allied conditions (e.g. allergic rhinitis)

             (SDDPI), HandiHaler® device, or pressurized Metered Dose Inhaler (MDI) (rescue
             medication).

             visit or during the run-in period. Inactivated influenza vaccination, pneumococcal
             vaccination or any other inactivated vaccine was acceptable provided it was not
             administered within 48 hours prior to screening and randomization visits.

        No additional exclusions were applied by the investigator, in order to ensure that the
        study population was representative of all eligible patients.
