A Study of a New Asthma Medicine in Asthmatics Whose Asthma Worsens With Exercise

19. juni 2014 opdateret af: GlaxoSmithKline

A Randomized, Double-Blind, Double-Dummy, Crossover Comparison of Fluticasone Furoate/Vilanterol 100/25 mcg Once Daily Versus Fluticasone Propionate 250 mcg Twice Daily in Asthmatic Adolescent and Adult Subjects With Exercise-Induced Bronchoconstriction

The primary objective of this study is to demonstrate that the combination of inhaled fluticasone furoate/vilanterol (100 mcg/25 mcg) once daily provides superior protection throughout the day against bronchoconstriction induced by exercise compared with fluticasone propionate 250 mcg twice daily in adolescent and adult subjects aged 12 to 50 diagnosed with persistent asthma.
