Key inclusion criteria
Inclusion criteria:

- Subjects with a documented history of persistent asthma, with the exclusion of other
significant pulmonary diseases

- Female subjects of non-child bearing potential (i.e. post-menopausal or surgically

- Subjects who are current non-smokers, who have not used any inhaled tobacco products
(snuff is permitted) in the 12 month period preceding the screening visit and who have
a pack history of less than 10 pack years.

- Subjects with clinically stable persistent asthma within the 4 weeks preceding the
screening visit and with a screening pre-bronchodilator FEV1 between 60 and 90%
predicted (having abstained from bronchodilators for the required period). Predicted
values are based on the ECCS 1993 normal ranges

- During the screening visit, subjects must demonstrate the presence of reversible
airway disease, defined as an increase in FEV1 of greater than 12.0% over baseline and
an absolute change of greater than 300 mL within 30 minutes following a single 400 mcg
salbutamol dose.

- Subjects who are currently taking ICS at a total daily dose of 200 to 500 mcg of FP or
equivalent ICS
Minimum age
18 Years
Maximum age
70 Years
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
Exclusion criteria:

- Subjects who have a past or present disease, which as judged by the Investigator and
the Medical Monitor, which may affect the safety of the subject or outcome of this

- A screening Holter ECG tracing that reveals clinically concerning arrhythmias
(including, but not limited to, ventricular ectopic runs of 4 beats, R on T phenomena,
bigeminy, trigeminy).

- A mean QTc(B) value at screening >430 msec (male) / >450 msec (female) or an ECG that
is not suitable for QT measurements (e.g. poorly defined termination of the T wave).

- Any adverse reaction including immediate or delayed hypersensitivity to any ß2 agonist
or sympathomimetic drug, or known or suspected sensitivity to the constituents of
GW642444 inhalation powder (e.g., lactose or COA).

- Subjects weighing < 50 kg

- Subjects who have participated in any GSK study involving administration of COA.

Brief summary
This is a study of GW642444M, a long-acting beta 2 specific agonist. This study will examine
GW642444M via the inhaled route and will assess the efficacy, safety, tolerability,
pharmacodynamics and pharmacokinetics of a single administration of three inhaled doses (25,
100 and 400 µg) of GW642444M in persistent asthmatics. This study will be a single-centre,
placebo-controlled, dose-ascending, five-way crossover in 30 asthmatic patients.

Key assessments: efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics will
be assessed by measurement of FEV1, blood pressure, pulse rate, 12-lead ECGs, clinical
laboratory safety tests, collection of adverse events and blood samples.
