Characterization of Lung Function Profile of Inhaled Tiotropium + Olodaterol Fixed Dose Combination Compared to Fluticasone Propionate + Salmeterol Fixed Dose Combination in COPD Patients

Randomized, Double-blind, Double-dummy, Active-controlled, 4 Period Complete Cross-over Study to Compare the Effect on Lung Function of 6 Weeks Once Daily Treatment With Orally Inhaled Tiotropium+Olodaterol Fixed Dose Combination Delivered by the Respimat® Inhaler vs. 6 Weeks Twice Daily Treatment With Fluticasone Propionate+Salmeterol Fixed Dose Combination Delivered by the Accuhaler® in Patients With Chronic Obstructive Pulmonary Disease (COPD)

The objective of the trial is to compare the lung function profile of once daily treatment with tiotropium+olodaterol FDC [2.5/ 5µg and 5/ 5µg] delivered by the RESPIMAT with the lung function profile of twice daily treatment with fluticasone propionate+salmeterol FDC [250/50µg and 500/50µg] delivered by the Accuhaler® after 6 weeks of treatment.
