Study Summary

The primary objective of this study is to determine the optimum dose(s) of BI 1744 CL inhalation solution delivered by the Respimat® inhaler for four weeks in patients with chronic obstructive pulmonary disease (COPD). The selection of the optimum dose(s) will be based on bronchodilator efficacy (how well it helps your breathing), safety evaluations and pharmacokinetic evaluations (the amount of the medication found in your blood).

Primary Outcome

Trough FEV1 is defined as the mean of the two FEV1 values (performed at -1 hour and -10 minutes prior to test-drug inhalation) at the end of the dosing interval, 24 hours post-drug administration. Trough FEV1 response is defined as the change from baseline in trough FEV1. Baseline FEV1 is the mean of the two pre-treatment FEV1 values measured at Visit 2 (- 1 hour and - 10 minutes) prior to administration of the first dose of study medication.
