The objective of this study is to evaluate the effect of the combination of formoterol and beclometasone dipropionate on central and peripheral airway dimensions in COPD patients using Computational Fluid Dynamics (CFD). Further more, the effect of this combination therapy on lung function (spirometry, body plethysmography), the BODE index, COPD assessment test (CAT) and Borg CR10 scale will be assessed and the safety will be evaluated.

BODE index
The BODE index is a multidimensional index of disease severity . The index uses following parameters: * body mass index (BMI) * degree of airflow obstruction (Forced Expiratory Volume in 1 second (FEV1): % of predicted) * functional dyspnea (Modified Medical Reseach Council (MMRC) dyspnea scale) * exercise capacity (6 minute walk distance (6MWD) - m)
Time frame: at baseline (visit 2), after 3 months of treatment (visit 5) and after 6 months of treatment (visit 8)
COPD assessment test
The COPD assessment measures the impact of COPD on a person's life.
Time frame: at screening (visit 1), at baseline (visit 2), after 3 months of treatment (visit 5) and after 6 months of treatment (visit 8)

Borg CR10 Scale
The Borg CR10 Scale measures the present dyspnea.
Time frame: At screening, at baseline both pre and post dose (visit 2), after 3 months of treatment (visit 5) and after 6 months of treatment both pre and post dose (visit 8)
Adverse events as a measure of safety
During the study patients will record record each day taken medication and any possible comments on the daily diary cards. Further more, patients are contacted at least once a month (either by phone or at a visit in the hospital).
