Exclusion criteria
Exclusion criteria: A subject will not be eligible for inclusion in this study if any of the following criteria apply: 1. History of upper or lower respiratory tract infection and/or exacerbation of asthma within 4 weeks of Visit 1. 2. History of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnoea, respiratory arrest or hypoxic seizures. 3.A history of 2 or more asthma exacerbations requiring treatment with oral corticosteroids or requiring hospitalisation in the 6 months before Visit 1. 4.Previously enrolled in this study, or currently participating or have participated in another study during the last 3 months (if the study involves a new chemical entity) or 2 months (if the product is already launched and commercially available). 5.Past or present disease which, as judged by the Investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, haematologic disease, neurological disease, endocrine disease or pulmonary disease (including, but not confined to, chronic bronchitis, emphysema, bronchiectasis with the need of treatment, cystic fibrosis and bronchopulmonary dysplasia). 6.Known or suspected sensitivity to the constituents of ROTADISKs (e.g. lactose) or severe milk protein allergy. 7.Undergoing allergen desensitisation therapy. 8.Subjects who are likely to be non-compliant with study medication and other study-related requirements (e.g. attendance at clinic visits or completion of daily record cards). 9.Neurological or psychiatric disease or history of drug or alcohol abuse which would interfere with the subject’s proper completion of the protocol requirements. 10.Is a current smoker or has a smoking history of 10 pack years or more (e.g. 20 cigarettes/day for 10 years).

(Usage of inhaled SABA is permitted - see Section 9.1) 16.Administration of ketotifen within 2 weeks of Visit 1. 17.Pregnant or lactating females. At the end of the Run-In period subjects must not meet any of the following additional criteria in order to enter the treatment period of the study. 1.Evidence of clinically significant abnormality, as judged by the investigator, in the haematological, biochemical or urinalysis screen at Visit 1. 2.Evidence of clinically significant abnormality, as judged by the investigator, in the 12-lead ECG at Visit 1. 3.Changes in asthma medication (excluding rescue salbutamol/albuterol provided at Visit 1). 4.Occurrence of an upper or lower respiratory tract infection during the run-in period. 5.Exacerbation of asthma during the run-in period.

| Primary end point(s): Mean change from baseline in (pre-dose and pre-bronchodilator) daily trough morning peak expiratory flow (PEF) during the 28-day treatment period.;Secondary Objective: The secondary objectives are to evaluate the safety of 500µg AM, 500µg PM and 1000µg of GW799943X AM administered once-daily via the ROTADISK™/ DISKHALER™ compared with placebo over a 28-day treatment period and to compare the relative efficacy and safety of 500µg and 1000µg of GW799943X once-daily with fluticasone propionate 250µg BD. To evaluate the effect of time of dosing (morning vs evening) of GW799943X 500µg once daily, administered by inhalation via the ROTADISK/DISKHALER upon efficacy and safety during the 28-day treatment period. ;Main Objective: The primary objective is to evaluate the efficacy of 500µg GW799943X am dosing, 500mcg GW799943X pm dosing, and 1000µg of GW799943X am dosing once-daily inhaled via the ROTADISK™/ DISKHALER™ compared with placebo over a 28-day treatment period. | — |
