• Diagnosis of asthma at least 6 months prior to screening.
• Patients must be controlled on their existing asthma treatment at Screening as defined by a Childhood Asthma Control Test score of >19 and PEF (Peak Expiratory Flow) >75 % predicted.
• Subjects must be taking a stable regimen of fluticasone propionate (≤200 μg (micrograms) twice daily or equivalent) and short acting beta-agonist inhaler on an as-need basis for at least 4 weeks prior to screening.
• Apart from asthma, eczema and rhinitis, subjects should be healthy and suffer from no other significant medical conditions.
• Subjects must weigh at least 15 kg (kilograms).
• Subjects must demonstrate ability to accept and effectively use the GW642444 device using the demonstration kits provided to the site.
• The subject and parent or guardian are able to understand and comply with protocol requirements, instructions, and protocol-stated restrictions. The parent or guardian must have the ability to read, write and record diary information collected throughout the study. The parent or guardian must also have the ability to manage study drug administration and PEF assessments.
• At least one parent or guardian has signed and dated the written informed consent prior to admission to the study. This will be accompanied by informed assent from the subject.

• Subjects currently receiving (or have received within 4 weeks of screening) any of the following asthma therapies: theophyllines, long-acting inhaled beta-agonists, oral beta-agonist.
• Subjects who have changed their asthma medication within 4 weeks of screening.
• Clinical visual evidence of oral candidiasis at screening.
• Any clinically relevant abnormality identified on the screening medical assessment
• Any medical condition or circumstance making the subject unsuitable for participation in the study (e.g. history of life-threatening asthma)
• Asthma exacerbation requiring systemic corticosteroids (oral, intramuscular, intravenous) or Emergency Room attendance within 3 months or asthma exacerbation requiring hospitalization within 6 months prior to the screening visit.
• Culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract which is not resolved within 4 weeks of the screening visit.
• Any adverse reaction including immediate or delayed hypersensitivity to any betaagonist therapy.
• Known or suspected sensitivity to the constituents of the novel dry powder inhaler (i.e., lactose or magnesium stearate), for example, history of severe milk protein allergy.
• The parent or guardian has history of psychiatric disease, intellectual deficiency, substance abuse, or other condition (e.g., inability to read, comprehend or write) which will limit the validity of consent to participate in this study.
