Study on BI 54903 (Inhaled Corticosteroid) Administered Once Daily or Twice Daily Via Respimat Inhaler in Patients With Asthma Inadequately Controlled on Short Acting Beta-2 Agonist (SABA) Therapy Alone

A Randomised, Double-blind, Double-dummy, Placebo-controlled, Parallel-group Study Assessing Efficacy and Safety of a 12 Week Treatment With BI 54903 Administered at 90.9 Mcg b.i.d. and 181.8 Mcg q.d. (p.m.Dosing) Via Respimat® Inhaler in Patients With Asthma Inadequately Controlled on Short Acting Beta-2 Agonist (SABA) Therapy Alone

The aim of this study is to assess and compare efficacy and safety of BI 54903 at doses of very low dose twice daily (b.i.d) and low dose once daily (evening dosing) and placebo over an 12-week treatment period in asthmatic patients aged 12 to 65 years inadequately controlled on short acting beta-2 agonist (SABA) therapy alone as demonstrated by a decrease in forced expiratory volume in 1 second (FEV1) (not less than 10 %, and equal to or less than 25%) and an Asthma Control Questionnaire (ACQ-6) of not less than 1.5 at time of randomisation.

10. During the run-in period (at the same clinic visit) all patients must be both symptomatic (ACQ-6 mean score equal to or greater than 1.5) and have shown a decrease in morning pre-bronchodilator FEV1 not less than 10% and less than or equal to 25% from pre-screening baseline FEV1 at Visit 2.

Exclusion criteria:

1. Patients with significant pulmonary disease other than asthma or other significant medical conditions (as determined by medical history, examination and clinical investigations at screening) that may, in the opinion of the investigator, result in any of the following: (i) put the patient at risk because of participation in this 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 haematology and/or blood chemistry finding, if the abnormality indicates a significant disease as defined in exclusion criterion no. 1.
3. Patients with a history of upper or lower respiratory tract infection (URTI/LRTI) in the past four weeks prior to the pre-screening Visit 1, and during pre-screening and run-in periods.
4. Patients with any exacerbation of their underlying asthma during the eight weeks prior to the pre-screening Visit 1.
5. Patients with active allergic rhinitis requiring treatment with systemic corticosteroids.

6. Any of the following criteria are met during the pre-screening / run-in period (Visits 1 - 6):

   1. in clinic pre-bronchodilator FEV1 % predicted less than 40%,
   2. more than 12 puffs rescue salbutamol/albuterol HFA MDI per day for > 2 consecutive days,
   3. exacerbation of asthma.
7. Patients with a history of pneumonectomy or who are planning to undergo thoracotomy for any reason.
8. Patients who are currently in a pulmonary rehabilitation program or have completed a pulmonary rehabilitation program in the six weeks prior to the first screening visit 1.
9. Patients with two or more hospitalizations for asthma within the previous 12 months.
10. Patients with a recent history of myocardial infarction during the last twelve months or known coronary heart disease that requires treatment
11. Patients with a history of hospitalisation due to heart failure in the past twelve months
