E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This is a confirmatory phase III trial to evaluate efficacy and safety of a 48-week treatment with two doses (2.5 micrograms and 5 micrograms) of tiotropium bromide compared to placebo administered via the Respimat device in adolescent patients (12 to 17 years old) with moderate persistent asthma. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objectives include the evaluation of several additional lung function parameters, asthma control and quality of life (using questionnaires), use of rescue medication and evaluation of asthma exacerbations. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. All patients and their parents (or legally accepted caregiver) must sign and date an informed consent consistent with ICH-GCP guidelines and local legislation prior to participation in the trial, i.e. prior to any study procedures including medication washout and restrictions. A separate informed consent is required for pharmacogenomic sampling (consent for pharmacogenomic sampling is not a prerequisite for study entry). 2. Male or female patients between 12 and 17 years of age. 3. All patients must have at least a 3 months history of asthma at the time of enrolment into the trial. The diagnosis of asthma has to be confirmed at visit 1 with a bronchodilator reversibility to a beta-2-adrenergic drug (15 to 30 minutes after 400 micrograms salbutamol (albuterol)) resulting in a FEV1 increase of >= 12% and >= 200mL, as per inclusion criterion No.7. 4. All patients must have been on maintenance treatment with inhaled corticosteroids at a stable medium dose (i.e., >= 400 micrograms to <= 800 micrograms Budesonide or equivalent, either as mono treatment or in combination with a LABA or leukotriene modifier for at least 4 weeks before Visit 1. While the LTRA is permitted throughout the trial, the LABA has to be stopped at least 24 hours prior to Visit 1, as no LABAs are permitted during run-in and treatment period of this trial.). 5. All patients must be symptomatic (partly controlled) at Visit 1 (screening) and prior to randomisation at Visit 2 as defined by an ACQ mean score of >= 1.5. 6. All patients must have a pre-bronchodilator FEV1 >= 60% and <= 90% of predicted normal at Visit 1. Variation of absolute FEV1 values of Visit 1 (pre-bronchodilator) as compared to Visit 2 (pre-dose) must be within +or- 30%. 7. All patients must have an increase in FEV1 of >= 12% and >= 200 mL 15 to 30 minutes after 400 micrograms salbutamol (albuterol) at Visit 1. If patients in the lower age range (e.g., 12 to 14 year olds) exhibit a very small total lung volume, positive reversibility testing might be based solely on the relative (>=12%) post-bronchodilator response. 8. All patients should be never-smokers or ex-smokers who stopped smoking at least one year prior to enrolment. A history of second-hand (e.g. parental) smoking should be documented. 9. Patients should be able to use the Respimat inhaler correctly. 10. Patients must be able to perform all trial related procedures including technically acceptable spirometric manoeuvres, according to ATS/ERS standards and the use of the electronic diary/peak flow meter. |

E.4 | Principal exclusion criteria |
1. Patients with a significant disease other than asthma. A significant disease is defined as a disease which, in the opinion of the investigator, may (i) put the patient at risk because of participation in the trial, or (ii) influence the results of the trial, or (iii) cause concern regarding the patient`s ability to participate in the trial. 2. Patients with clinically relevant abnormal screening haematology or blood chemistry will be excluded if the abnormality defines a significant disease as defined in exclusion criterion 1. 3. Patients with a history of congenital or acquired heart disease, and/or have been hospitalised for cardiac syncope or failure during the past year. 4. Patients with any unstable or life-threatening cardiac arrhythmia or cardiac arrhythmia requiring intervention (e.g. ICD or pacemaker implantation) or a change in drug therapy within the past year. 5. Patients with malignancy for which the patient has undergone resection, radiation therapy or chemotherapy within the last five years. 6. Patients with lung diseases other than asthma (e.g. CF). In case of ex-premature infants, a history of significant bronchopulmonary dysplasia will be regarded as exclusion criterion. 7. Patients with known active tuberculosis. 8. Patients with significant alcohol or drug abuse within the past two years. 9. Patients who have undergone thoracotomy with pulmonary resection. Patients with a history of thoracotomy for other reasons should be evaluated as per exclusion criterion No. 1. 10. Patients who are currently in a pulmonary rehabilitation program or have completed a pulmonary rehabilitation program in the 6 weeks prior to the screening visit (Visit 1). 11. Patients with known hypersensitivity to anticholinergic drugs, BAC, EDTA or any other components of the tiotropium inhalation solution. 12. Pregnant or nursing adolescent female patients, including female patients with a positive β-HCG (serum pregnancy) testing at screening (Visit 1). 13. Sexually active female patients of child-bearing potential not using a highly effective method of birth control. 14. Patients who have taken an investigational drug within 4 weeks prior to Visit 1. 15. Patients who have been treated with long-acting anticholinergics (e.g. tiotropium - Spiriva) within four weeks prior to screening (Visit 1). 16. Patients who are unable to comply with pulmonary medication restrictions prior to randomisation. 17. Patients who have been treated with Anti-IgE treatment within the last 6 months prior to screening. 18. Patients who have been treated with systemic (oral or intravenous) corticosteroids within 4 weeks prior to screening. 19. Patients who have been treated with long-acting theophylline preparations within 2 weeks prior to screening (Visit 1) or during the run-in period. 20. Patients who have been treated with other non-approved and according to international guidelines not recommended ``experimental`` drugs for routine asthma therapy within four weeks prior to screening (Visit 1) or during run-in period. 21. Patients with any acute asthma exacerbation or respiratory tract infection in the 4 weeks prior to Visit 1. In case of an asthma deterioration occurring during the run-in period, see Section 6.1 for postponing of Visit 2. 22. Patients requiring 10 or more puffs of rescue medication (salbutamol) per day on more than 2 consecutive days during the run-in period. 23. Patients who have previously been randomised in this trial or are currently participating in another study. 24. Patients who are being treated with oral beta-blocker medication. Topical cardioselective beta-blocker eye medications for treatment of non-narrow angle glaucoma are allowed. 25. Patients with a known narrow-angle glaucoma, or any other disease where anticholinergic treatment is contraindicated. 26. Patients with renal impairment. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the peak FEV1 response (within 3 hours post dosing) determined at the end of 24weeks of treatment.Peak FEV1 is defined as the maximum value of the FEV1 measurements within 3 hours post dosing. Peak FEV1 response is defined as the change from baseline in peak FEV1. |
