A Study of a New Asthma Medicine in Asthmatics Whose Asthma Worsens With Exercise
2014年6月19日 更新者：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.
