Brief summary
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.
