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).

Primary Outcome Measures:
  • The primary efficacy variable will be forced expiratory volume in one second (FEV1). The primary endpoint is the trough FEV1 response [L] after four weeks of treatment [ Time Frame: 4 Weeks ]

Secondary Outcome Measures:
  • FEV1 and FVC responses at different timepoints Weekly mean predose morning and evening PEFR Weekly mean number of occasions of rescue therapy used per day Asthma Control Questionnaire [ Time Frame: 1, 2 and 4 Weeks ]

Enrollment: 296
Study Start Date: May 2007
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
