Comparing Two Respiratory Drugs When Used In Combination And Separately From A Novel Inhaler Device In Healthy Subjects
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
A combination of the corticosteroid GW685698X and the long-acting ß2-agonist GW642444M is being developed for once daily administration for the maintenance treatment of asthma and COPD. GW642444M and GW685698X will be simultaneously co-administered from a single device and compared with GW642444M and GW685698X administered separately in order to determine whether co-administration affects the safety, tolerability, pharmacodynamic and/or pharmacokinetics of either compound.
A Randomised, Double-blind, Placebo-controlled, Four-way Crossover Study to Compare the Pharmacodynamics and Pharmacokinetics of GW685698X and GW642444M When Administered Separately and in Combination as a Single Dose From a Novel Dry Powder Device in Healthy Subjects
