A clinical trial to study the effect of tiotropium in patients with moderate persistent asthma

A Phase III randomised, double-blind, placebo-controlled, parallel group trial to evaluate efficacy and safety of tiotropium inhalation solution delivered via Respimat® inhaler (2.5 and 5 mcg once daily) compared with placebo and salmeterol HFA MDI (50 mcg twice daily) over 24 weeks in patients with moderate persistent asthma

Eligibility

Inclusion criteria

Inclusion criteria: 1. All patients must sign and date an Informed Consent Form 2. Male or female patients aged at least 18 years but not more than 75 years. 3. All patients must have at least a 3 month history of asthma at the time of enrolment into the trial. The diagnosis should be confirmed at Visit 1 by fulfilling inclusion criterion 5. 4. The initial diagnosis of asthma must have been made before the patient's age of 40. 5. The diagnosis of asthma has to be confirmed at Visit 1 with a bronchodilator reversibility (15 minutes after 400 mcg salbutamol (albuterol)) resulting in a Forced Expiratory Volume in one second (FEV1) increase of at least 12% and at least 200mL. 6. All patients must have been on maintenance treatment with a medium, stable dose of inhaled corticosteroids for at least for 4 weeks prior to Visit 1. 7. All patients must be symptomatic at Visit 1 (screening) and prior to randomisation at Visit 2 as defined by an Asthma Control Questionnaire (ACQ) mean score of at least 1.5. 7. All patients must have a pre-bronchodilator FEV1 at least 60% and less than or equal to 90% of predicted normal at Visit 1. 8. Variation of absolute FEV1 values of Visit 1 (pre-bronchodilator) as compared to Visit 2 (pre-dose) must be within ± 30%. 9. Patients must be never-smokers or ex-smokers who stopped smoking at least one year prior to enrolment (Visit 0) and who have a smoking history of less than 10 pack years.

Exclusion criteria

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 a clinically relevant abnormal screening (Visit 1) haematology or blood chemistry if the abnormality defines a significant disease as defined in exclusion criterion 1. 3. Patients with a recent history (i.e. six months or less) of myocardial infarction. 4. Patients who have been hospitalised for cardiac failure during the past year. 5. Patients with any unstable or life-threatening cardiac arrhythmia or cardiac arrhythmia requiring intervention or a change in drug therapy within the past year. 6. Patients with lung diseases other than asthma (e.g. Chronic Obstructive Pulmonary Disease (COPD)). 7. Patients with known active tuberculosis. 8. Patients with malignancy for which the patient has undergone resection, radiation therapy or chemotherapy within the last five years. Patients with treated basal cell carcinoma are allowed. 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 with significant alcohol or drug abuse within the past two years. 11. Patients who are currently in a pulmonary rehabilitation program or have completed a pulmonary rehabilitation program in the 6 weeks prior to Visit 1 (screening). 12. Patients with known hypersensitivity to anticholinergic drugs, benzalkonium chloride (BAC), ethylenediamineteraacetic acid (EDTA), salmeterol xinafoate or any other components of the study medication delivery systems. 13. Pregnant or nursing woman. 14. Women of childbearing potential not using a highly effective method of birth control. 15. Patients who have taken an investigational drug within four weeks prior to Visit 1. 16. Patients who have been treated with beta-blocker medication within four weeks prior to Visit 1 and/or during the screening period. Topical cardio-selective beta-blocker eye medications for non-narrow angle glaucoma are allowed. 17. Patients who have been treated with the long-acting anticholinergic tiotropium (Spiriva®) within four weeks prior to Visit 1 and/or during the screening period. 18. Patients who have been treated with oral or patch beta-adrenergics within four weeks prior to Visit 1 and/or during the Screening period. 19. Patients who have been treated with oral corticosteroids within four weeks prior to Visit 1 and/or during the screening period. 20. Patients who have been treated with anti-IgE antibodies, e.g. omalizumab (Xolair®), within 6 months prior to Visit 1 and/or during the screening period. 21. Patients who have been treated with cromone within two weeks prior to Visit 1 and/or during the screening period. 22. Patients who have been treated with methylxanthines or phosphodiesterase 4 inhibitors within two weeks prior to Visit 1 and/or during the screening period. 23. 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 Visit 1 and/or during the screening period. 24. Patients with any asthma exacerbation or any respi
