Dataset from A Randomized, Double-blind, Placebo-controlled, Four-way Crossover Study to Evaluate and Compare the Pharmacodynamics and Pharmacokinetics of Fluticasone Furoate /Vilanterol in Different Dose Combination (50/25mcg, 100/25mcg and 200/25mcg) After Single and Repeat Dose Administration From a Novel Dry Powder Device in Healthy Chinese Subjects

In this study, fluticasone furoate (FF) and vilanterol (VI) in different dose combinations (50/25mcg, 100/25mcg and 200/25mcg) will be administered from a single dry powder device to evaluate the PD, PK, safety and tolerability of the combination in healthy Chinese subjects. The information gathered will be used as a support of the clinical development program of the fixed dose combination of FF/VI inhalation powder in Chinese population.
