Clinical Trial Summary

To establish that at least one of the two doses of Budesonide, as an ethanolic solution inhaled from the Respimat ® inhaler (100 and 200 mcg, 2 puffs bid) for a 12-week study period in symptomatic moderate to severe asthmatic patients, gives a therapeutic response, which is not inferior to that obtained from the dose of Budesonide inhaled from the Turbohaler ® (200 mcg, 2 puffs bid) and that the safety profile is at least as good

• Patient must demonstrate an improvement in FEV 1 >= 12% above baseline and an absolute change of at least 200 ml within 30 minutes after administration of two puffs of salbutamol MDI (metered dose inhaler) (100 mcg per puff). Historical data within the previous 6 months are acceptable

• Patients with clinically signification abnormal baseline haematology, blood chemistry or urinalysis (if the abnormality defines a disease listed as an exclusion criterion)

• Patients with any of the abnormal laboratory values below:

• SGOT (serum glutamate oxaloacetate transaminase) > 200% of the upper limit of the normal range

• SGPT (serum glutamate pyruvate transaminase) > 200% of the upper limit of the normal range

• Creatinine > 125% of the upper limit of the normal range

• Bilirubin > 150% of the upper limit of the normal range, with the exception of Gilbert's disease will be excluded regardless of the clinical condition

• Patients with known intolerance hypersensitivity to one of the aerosolized products including inhaled steroids (budesonide and beclomethasone dipropionate), salbutamol, ethylenediaminetetraacetic acid, ethanol, citric or oleic acid

• Patients using oral or other systemic (intramuscular or intravenous) corticosteroids in the past 8 weeks or other potent immunosuppressant (i.e. methotrexate) medication in the past 3 months

• Patients using beta blocker therapy, ACE inhibitors (an exception was provided if the ACE inhibitor have been at a stable dose for six months with no reported incidence of cough) monoamine oxidase inhibitors, tricyclic antidepressants, cromolyn or nedocromil sodium, ketotifen, astemizole or any other antihistamine drug, or a combination of an inhaled long acting ß2-agonist plus oral xanthine or having received an influenza vaccine within 1 week of Screening Visit 1

• Patients on nebulised ß2-agonists, anticholinergics or steroids in the 4 weeks before screening visit 1

• If a patient is on allergen desensitization therapy, this should have been as a maintenance dose for the previous 3 months and continued throughout the treatment period

• Unstable respiratory medication dosage in the last 4 weeks prior to screening visit 1

• Patients with a significant history and/or active alcohol or drug abuse. Significant is defined as that which in the opinion of the investigator may either put the patient at risk because of participation in the study or may influence the results of the study or the patient's ability to participate in the study

• Patients who have taken any investigational drug, one month or six half-lives (whichever is greater) prior to the Screening Visit
