TRIMBOW® and RELVAR® on Lung Stiffness Reduction Assessed Through Forced Oscillation Technique in Patients With COPD

An open label, multicentre, randomised, 2-way cross-over exploratory clinical trial comparing a fixed combination of beclometasone dipropionate plus formoterol fumarate plus glycopyrronium administered via pMDI (TRIMBOW®) and a fixed combination of fluticasone furoate plus vilanterol administered via DPI (RELVAR® ELLIPTA®) on lung stiffness reduction assessed through area under the reactance curve (AX) using forced oscillation technique (FOT) in patients with chronic obstructive pulmonary disease (COPD).
