E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the effect of 20 days 18 µg tiotropium bromide once daily on the airway responsiveness to neurokinin A in patients with mild asthma, in order to study the real contribution of the cholinergic activation by NKA, by an agent that is relatively selective for M3. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- All patients must sign and date an Informed Consent Form for the study consistent with ICH-GCP guidelines and local legislation prior to participation in the trial - Male or female with at least 18 years of age - Patients must have a documented history of asthma (at least 6 months) - Patients must be current non-smokers or ex-smokers with a cigarette smoking history of ≤ 10 pack-years (and smoking cessation et least one year prior to study enrolment) Pack years= (Number of cigarettes/day)/20 x years of smoking - Patients must be able to perform technically acceptable pulmonary, methacholine and neurokinin A (NKA) challenge tests - At Visit 1: PC20 methacholine ≤ 8 mg/mL AND ≤ 3.3x10-7 mol/mL for the NKA challenge test - At Visit1: FEV1 predicted ≥ 70% - Females must be of non-childbearing potential OR taking adequate contraceptive precautions AND not be a nursing mother |
|
E.4 | Principal exclusion criteria |
- Any respiratory tract infection or asthma exacerbation within 6 weeks of Visit1 - Respiratory diseases other than asthma (COPD, bronchiectasis, lung cancer, mesothelioma, cystic fibrosis, active tuberculosis) - Currently participation in another clinical study - Relevant concomitant systemic diseases other than asthma (malignancy, unstable cardial disease, moderate to severe renal impairment [creatinine clearance ≤ 50 mL/min]) - Clinically significant laboratory abnormalities - Alcohol or drug abuse

E.5 End points |
E.5.1 | Primary end point(s) |
The mean change in the provocative concentration of NKA causing a 20% fall of FEV1 (PC20 NKA), as a measure of indirect airway hyperresponsiveness, following 20 days of treatment with tiotropium. |
