Pulmonary Disease, Chronic Obstructive
Conditions
Brief summary
This efficacy and safety study compares four different combinations of blinded inhaled steroid treatments on top of open-label tiotropium and salmeterol in patients with chronic obstructive pulmonary disease (COPD). The primary objective is the effect on lung function parameters.
Interventions
