Dataset from A Randomized, Double Blind, Single-dose, Three-period, Crossover Study to Investigate Pharmacokinetic, Safety and Tolerability of Fluticasone Furoate With Umeclidinium When Administered in Combination and as Monotherapies in Adult Healthy Volunteer Subjects

This will be a randomized, double-blind, single-dose, three-period balanced crossover study in adult healthy subjects. Each of the 18 subjects will be randomized to receive a treatment sequence consisting of each of the three treatments (FF 400 microgram (mcg), UMEC 500 mcg and FF 400 mcg/UMEC 500 mcg), in three consecutive periods, with a wash-out period of 7 to 10 days between the periods. The study will include a Screening period (28 days prior to first dose), Treatment period (3 single dose periods separated by two 7 to 10 days washout periods) and Follow-up period (7 to 14 days post last dose). The pharmacokinetic (PK) and safety assessments will be performed during the study at fixed timepoints.
