Primary outcomePrimary: Trough FEV1 Response After 4 Weeks — 0.004; 0.083; 0.090; 0.080 Liter — p=0.0754
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 asthma. 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).
