Name Time Method Main Objective: This study evaluates the effects of 12-week treatment with two doses of tiotropium bromide (2.5 µg q.d. and 5 µg q.d.) compared to placebo administered via the Respimat® device on lung function in patients with CF.<br>;Secondary Objective: Selection of the optimal dose will be based on bronchodilator efficacy, safety<br>evaluations and pharmacokinetic evaluations. ;Primary end point(s): Co-primary endpoints:<br>- change from baseline in forced expiratory volume in one second (FEV1) area under<br>the curve (AUC)0-4h at the end of Week 12 (Visit 6)<br>- change from baseline in trough FEV1 at the end of Week 12 (Visit 6)
