             willing to continue this therapy for the entire duration of the study (exception:
             times of acute disease deterioration).

        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 hematology or blood chemistry
             if the abnormality defines a significant disease as defined in exclusion criterion no.
