- Respiratory Infection: Culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear that is not resolved within 4 weeks before Visit 1 and led to a change in asthma management, or in the opinion of the Investigator is expected to affect the subjects asthma status or the subjects ability to participate in the study.
- Asthma Exacerbation: Any asthma exacerbation requiring oral corticosteroids within 3 months of Visit 1. A subject must not have had any hospitalization for asthma within 6 months prior to Visit 1.
- Concurrent Diseases/Abnormalities: Historical or current evidence of clinically significant uncontrolled disease including, but not limited to: cardiovascular disease, hepatic disease, renal disease, hematological disease, neurological disease, or pulmonary disease (including, but not confined to chronic bronchitis, emphysema, bronchiectasis with the need of treatment, cystic fibrosis, bronchopulmonary dysplasia, and chronic obstructive pulmonary disease). Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study. The list of additional excluded conditions/diseases includes, but is not limited to the following: congestive heart failure, clinically significant coronary heart disease, stroke within 3 months of Visit 1, poorly controlled peptic ulcer, immunologic compromise, tuberculosis (current or untreated), Addison's disease, uncontrolled thyroid disorder, known aortic aneurysm, clinically significant cardiac arrhythmia, uncontrolled hypertension1, hematological, hepatic, or renal disease, current malignancy2, cushings disease, uncontrolled diabetes mellitus, recent history of drug or alcohol abuse.

- Attendance: A subject will not be eligible if he/she or his/her parent or legal guardian has any infirmity, disability, or geographical location which seems likely (in the opinion of the Investigator) to impair compliance with any aspect of this study protocol or scheduled visits to the study center and non-compliant with study medication or procedures (e.g. completion of daily diary). Neurological or psychiatric disease or history of drug or alcohol abuse which in the opinion of the investigator could interfere with the subject's proper completion of the protocol requirements excludes study participation.

- Clinical Laboratory Abnormalities: Clinically significant abnormal laboratory tests during Visit 1 which are still abnormal upon repeat analysis and are not believed to be due to disease(s) present. Each Investigator will use his/her own discretion in determining the clinical significance of the abnormality. When in doubt, GlaxoSmithKline, or designee, should be notified so that a joint decision can be made.
- Changes in asthma medication (excluding albuterol/salbutamol inhalation aerosol provided at Visit 1).
- Occurrence of an culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear during the run-in period that led to a change in asthma management, or in the opinion of the Investigator is expected to affect the subject's asthma status or the subject's ability to participate in the study.
- Asthma exacerbation, defined as any worsening of asthma requiring any treatment other than rescue albuterol/salbutamol or regular inhaled corticosteroid use. This includes requiring the use of systemic corticosteroids and / or emergency room visit or hospitalization or a change in subject's regular inhaled corticosteroid dose.
- A subject will not be eligible for randomization if he/she has an abnormal visual oropharyngeal exam at the randomization Visit 3 (visual clinical evidence of oral candidiasis).
