Clinical Trial Summary

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 asthmatic patients using Computational Fluid Dynamics (CFD). Further more, the effect of this combination therapy on exhaled NO, lung function (spirometry, body plethysmography, diffusion and resistance) and subjective asthma control score as well as the safety of this combination will be assessed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Differences in airway dimension	The primary objective of this study is to evaluate the effect of the combination therapy on central and peripheral airway dimensions with CFD. The following primary outcome parameters will be determined: Total airway resistance for the segmented airways; Peripheral airway resistance(from 4th bifurcation on) for the segmented airways; Total airway volume for the segmented airways; Peripheral airway volume (from the 4th bifurcation on) for the segmented airways; Relative compliance for each lobe; Density of the lung parenchyma given per predefined lung zone	airway dimension will be measured at visit 2 and visit 7	No
Secondary	Lung function tests: dynamic lung volumes, static lung volumes and airway resistances	The secondary outcome parameters that will be obtained with the lung function tests are: Dynamic lung volumes: Forced Expiratory Volume in 1 sec (FEV1), Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF),Maximum expiratory flow when 50% of the FVC remain to be exhaled (MEF50) , Maximum expiratory flow when 25% of the FVC remain to be exhaled (MEF25); Static lung volumes: Vital Capacity (VC),Inspiratory Vital Capacity (IVC), Functional Residual Capacity (FCR), Total Lung Capacity (TLC); Airway resistances: Airway Resistance (Raw), Specific Airway Conductance(SGaw) (based on body plethysmography)	lung function tests will be perfomed at te following visits: screening, visit 1 (2 weeks after screening), visit 3 (6 weeks after screening), visit 5 (14 weeks after screening) and visit 7 (26 weeks after screening)	No
Secondary	Subjective asthma control score	Asthma control scores will be obtained with the Dutch Asthma Control Test.	Asthma Control Test (ACT) will be performed on visit 1, 2, 3, 5 and 7	No
Secondary	Exhaled Nitric Oxide (NO)		Exhaled NO will be measured on visit 2, 3, 5 and 7	No
Secondary	Adverse events as a measure of safety		Follow up of adverse events will be done during the entire study duration	Yes
