  Purpose

The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium compared to placebo over 12 week treatment period. Tiotropium inhalation solution will be delivered via Respimat inhaler and will be examined on top of maintenance inhaled corticosteroid treatment in patients with mild persistent asthma. Efficacy and safety will be assessed by measuring the effects on lung functions, effects on lung exacerbations, effects on asthma control and numbers of adverse events.

Primary Outcome Measures:
  • Peak Forced Expiratory Volume in 1 Second (FEV1) Response Within 3 Hours Post Dosing (0-3h) After a Treatment Period of 12 Weeks. [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
    Peak FEV1 0-3h response was defined as the difference between the maximum FEV1 measured within the first 3 hours post dosing after a treatment period of 12 weeks and the FEV1 baseline measurement (10 minutes before the first dose of trial medication). Mixed Model Repeated Measure (MMRM) results. Means are adjusted for treatment, pooled centre, visit, baseline, treatment*visit and baseline*visit.


Secondary Outcome Measures:
  • Trough FEV1 Response Determined After a Treatment Period of 12 Weeks. [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
    The trough FEV1 is defined as the pre-dose FEV1 measured 10 minutes before the last administration of randomised treatment. Trough FEV1 response was defined as the difference between the trough FEV1 measured after a treatment period of 12 weeks and the trough FEV1 baseline measurement. MMRM results. Means are adjusted for treatment, pooled centre, visit, baseline, treatment*visit and baseline*visit.

  • Peak (Within 3 Hours Post-dosing) Forced Vital Capacity (FVC) Response at the End of the 12-week Treatment Period. [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
    Peak FVC 0-3h response was defined as the difference between the maximum FVC measured within the first 3 hours post dosing after a treatment period of 12 weeks and the FVC baseline measurement (10 minutes before the first dose of trial medication). Mixed Model Repeated Measure (MMRM) results. Means are adjusted for treatment, pooled centre, visit, baseline, treatment*visit and baseline*visit.

  • FEV1 Area Under the Curve (AUC0-3h) Response at the End of the 12-week Treatment Period. [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
    The AUC0-3h was calculated as area under the curve from zero to 3 hours using the trapezoidal rule divided by the observation time (3 hours) to report in litres. The trough value was assigned to zero time. Response was defined as change from baseline in FEV1 AUC0-3h after a treatment period of 12 weeks. MMRM results. Means are adjusted for treatment, pooled centre, visit, baseline, treatment*visit baseline*visit.

  • FVC (AUC0-3h) Response at the End of the 12-week Treatment Period. [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]
    The AUC0-3h was calculated as area under the curve from zero to 3 hours using the trapezoidal rule divided by the observation time (3 hours) to report in litres. The trough value was assigned to zero time. Response was defined as change from baseline in FVC AUC0-3h after a treatment period of 12 weeks. MMRM results. Means are adjusted for treatment, pooled centre, visit, baseline, treatment*visit baseline*visit.

  • Asthma Control Questionnaire (ACQ) Responder After 12 Weeks of Treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    For the ACQ, the total score was calculated as the mean of the responses to 6 self administered questions and one question which was completed by clinical staff based upon pre-bronchodilator FEV1. The score ranges from 0 (no impairment) to 6 (maximum impairment). Response was categorised as: responder (change from baseline <= -0.5), no change (-0.5 <change from baseline < 0.5) and worsening (change from baseline >= 0.5).

  • Time to First Severe Asthma Exacerbation During the 12-week Treatment. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Severe asthma exacerbations are defined as all asthma exacerbations that required treatment with systemic (including oral) corticosteroids for at least 3 days.

  • Time to First Asthma Exacerbation During the 12-week Treatment. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    An asthma exacerbation was defined as an episode of progressive increase in 1 or more asthma symptom that were outside the patient's usual range of day-to-day asthma symptoms and lasted for at least 2 consecutive days or as a decrease in a patient's best morning PEF of 30% or more from a patient's mean morning PEF for at least 2 consecutive days that may or may not have been accompanied by symptoms.

All patients must sign and date an Informed Consent Form consistent with International Conference on Harmonisation -Good Clinical Practice (ICH-GCP) guidelines and local legislation prior to participation in the trial (i.e. prior to any trial procedures, including any pre-trial washout of medications and medication restrictions for pulmonary function test at Visit 1).
