What's being measured

Primary outcomes are the specific endpoints the trial is designed to prove or disprove.

• Peak FEV1 Within 3 Hours Post-dose Response
  Time frame: 24 weeks
  Peak forced expiratory volume in one second (FEV1) response within 3 hours post-dose determined at the end of the 24-week treatment. Response was defined as change from baseline (10 minutes before the first dose of trial medication at visit 2). Means are adjusted for treatment, centre, week, baseline, treatment by week, and baseline by week.
• Trough FEV1 Response
  Time frame: 24 weeks
  Trough FEV1 response determined at the end of the 24-week treatment. Response was defined as change from baseline (10 minutes before the first dose of trial medication at visit 2). Means are adjusted for treatment, centre, week, baseline, treatment by week, and baseline by week.
• The Responder Rate as Assessed by the ACQ From the Two Twin Trials 205.419 (NCT01172821) and the Present 205.418 (NCT01172808)
  Time frame: 24 weeks
  The responder rate as assessed by the Asthma Control Questionnaire (ACQ) determined at the end of the 24-week treatment period (on combined data from the two twin trials 205.418 (NCT01172808) and 205.419 (NCT01172821)). A patient was considered to be a responder if he or she was reported with an improvement (decrease) in the ACQ total score of at least 0.5 points. The ACQ total score was calculat

Sponsor's own description

The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium over a 24-week treatment period as compared to placebo and salmeterol (50 mcg twice daily). Tiotropium inhalation solution delivered by the Respimat® inhaler will be examined on top of maintenance treatment with inhaled corticosteroid controller medication in patients with moderate persistent asthma. Efficacy and safety will be assessed by measuring effects on lung function, effects on asthma exacerbations, effects on quality of life, effects on asthma control, effects on health care resource utilisation, and number of adverse events.
