          7. Ability to perform acceptable and reproducible spirometry.

          8. Post-bronchodilator (four puffs of albuterol) spirometry at Screening demonstrating
             the following:

               -  FEV1/Forced Vital Capacity (FVC) ratio of ≤0.70

               -  FEV1 ≥40 % and ≤80% of predicted normal

               -  ≥150 mL increase from pre-bronchodilator FEV1

          9. Clinically stable COPD in the 4 weeks prior to Screening and during the period between
             Screening and Part A.

         10. A chest X-ray showing no abnormalities, which are both clinically significant and
             unrelated to COPD.

         11. Meet the concomitant medication restrictions and be expected to do so for the rest of
             the study.

         12. Current and former smokers with smoking history of ≥10 pack years. 14. Capable of
             withdrawing from long acting bronchodilators for the duration of the study, and short
             acting bronchodilators for 8 hours prior to dosing.

        Exclusion Criteria:

          1. A history of life-threatening COPD including Intensive Care Unit admission and/or
             requiring intubation.

             recent (<1 year) or suspected myocardial infarction, congestive heart failure,
             unstable or uncontrolled hypertension, or diagnosis of hypertension within 3 months

         15. Major surgery (requiring general anesthesia) within 6 weeks prior to Screening, lack
             of full recovery from surgery at Screening, or planned surgery through the end of the
             study.

         16. A disclosed history or one known to the Investigator, of significant non compliance in

             biochemistry, viral serology or urinalysis) at Screening, as determined by the
             Investigator. In particular, alanine aminotransferase or aspartate aminotransferase
             cannot be more than twice the upper limit of normal.

         20. Any other reason that the Investigator considers makes the patient unsuitable to
             participate.
