Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the study is to compare Symbicort® (budesonide 160 µg/inhalation and formoterol fumarate dihydrate 4.5 µg /inhalation) as Single Inhaler Therapy, with a Subject’s previous therapy (including low dose inhaled corticosteroids), by assessment of the changes in the Asthma Control Questionnaire (ACQ) in uncontrolled asthmatic Subjects.;Secondary Objective: Not applicable.;Primary end point(s): The primary outcome variable is the change in ACQ score from baseline (visit 2) to the average value of available data for visits 3-5. In addition, the change in ACQ score from baseline (visit 2) to 4 weeks (visit 3) will be analysed to assess whether Symbicort® Single Inhaler Therapy provides an early onset of action.
