A 52 WEEK, RANDOMIZED, DOUBLE BLIND, MULTINATIONAL, MULTICENTRE, ACTIVE CONTROLLED, 3-ARM PARALLEL GROUP TRIAL COMPARING CHF 5993 200/6/12.5 µg pMDI (FIXED COMBINATION OF EXTRAFINE BECLOMETASONE DIPROPIONATE PLUS FORMOTEROL FUMARATE PLUS GLYCOPYRRONIUM BROMIDE) TO CHF 1535 200/6 µg pMDI (FIXED COMBINATION OF EXTRAFINE BECLOMETHASONE DIPROPIONATE PLUS FORMOTEROL FUMARATE) ALONE OR ON TOP OF OPEN-LABEL TIOTROPIUM 2.5 µg RESPIMAT® IN PATIENTS WITH ASTHMA UNCONTROLLED ON HIGH DOSES OF INHALED CORTICOSTEROIDS IN COMBINATION WITH LONG-ACTING ß2-AGONISTS

The purpose of this study is to evaluate the superiority of CHF 5993 200/6/12.5 µg pMDI (fixed combination of extrafine beclometasone dipropionate plus formoterol fumarate plus glycopyrronium bromide) versus CHF 1535 200/6 µg pMDI (fixed combination of extrafine beclometasone dipropionate plus formoterol fumarate) and to compare the effect of CHF 5993 200/6/12.5 µg pMDI vs CHF 5993 200/6/12.5 µg plus open-label Tiotropium 2.5µg, in terms of lung functions parameters and rate of exacerbations, as well as to assess its safety and some health economics outcomes.
