Brief summary
This study is a multi-centre, randomised, double-blind, placebo-controlled (with rescue medication), two period crossover study in subjects with persistent uncontrolled asthma, currently not treated with an inhaled corticosteroid (ICS) or long acting beta 2 agonist (LABA). This study is the first administration of GSK2269557 to asthmatic subjects, and the aims of the study are to investigate the efficacy, safety, tolerability, and pharmacokinetics of four weeks of treatment with orally inhaled GSK2269557 1000 microgram (mcg) in subjects with persistent uncontrolled asthma. In a sub-study, biological mediators will be measured from induced sputum and blood. Approximately 50 subjects will be randomised into the study (including approximately 16 subjects in the sputum sub-study). Each subject will complete two treatment periods: subjects will be randomised to receive GSK2269557 1000 mcg in one treatment period, and matching placebo in the other treatment period. Each treatment will be administered once daily for 28 days (+/- 2 days) via the DISKUS™ dry powder inhaler (DPI). The study will consist of a Screening Visit; a Run-in Period (approximately 2 weeks in duration); two 28-day Treatment Periods (each with 4 clinic visits); a 4-week Washout Period (between the Treatment Periods); and a Follow-up Visit. The total duration of the study for each subject will be approximately 16 weeks. DISKUS is a registered trademark of the GlaxoSmithKline group of companies.

Change From Baseline in Trough Forced Expiratory Volume in One Second (FEV1) at Day 28 in Intent-To-Treat (ITT) Population
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 is the maximum volume of air that can be forced out in one second after taking a deep breath approximately 24 hours after the last administration of study drug. FEV1 was measured using a spirometer. Change from Baseline is calculated as post-Baseline value minus Baseline value where Baseline is defined as Day 1 (pre-dose).
Time frame: Baseline and Day 28 for each treatment period
Population: The analysis was performed on the ITT Population which comprised of all participants who received at least one dose of trial medication and have at least one post-dose efficacy assessment. Six participants had entered the study without spirometric evidence of disease, and were excluded from the ITT population prior to unblinding.

Change From Baseline in Forced Vital Capacity (FVC) at Day 7, Day 14 and Day 28
FVC is defined as the total amount of air exhaled during the FEV test. Data was collected pre-dose at Baseline (Day 1), Day 7, Day 14 and Day 28. Change from Baseline was calculated as the post-Baseline value minus the Baseline value where Baseline was defined as Day 1 (pre-dose). The number of participants with data available at the specified time points are represented by n=X in the category titles.

Change From Baseline in Trough FEV1 at Day 7 and Day 14
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. The trough FEV1 is the maximum volume of air that can be forced out in one second after taking a deep breath approximately 24 hrs after the last administration of study drug. Change from Baseline values were calculated as post-Baseline values minus Baseline value where Baseline was defined as Day 1 (pre-dose). The number of participants with data available at the specified time points are represented by n=X in the category titles.

Change From Baseline in Trough Fractional Exhaled Nitric Oxide (FeNO) at Day 7, Day 14 and Day 28
Participants with asthma have high levels of NO in their exhaled breath. Evaluation of FeNO is a quantitative, noninvasive method of measuring airway inflammation to assess airway diseases including asthma. FeNO was measured in the clinic using a handheld electronic device. Change from Baseline for Day 7, Day 14 and Day 28 was calculated as the post-Baseline value minus the Baseline value where Baseline was defined as Day 1 (pre-dose).

Mean Number of Inhalations Per Day of Rescue Medication (Salbutamol) Over the Treatment Period
Daily recordings of rescue medication use were collected in an eDiary by participants.

Number of Participants With Abnormal Values of Hematology Parameters
Blood samples were collected from participants for evaluation of hematology parameters by Potential Clinical Importance Criteria. The hematology parameters included hematocrit, hemoglobin, lymphocytes, total neutrophils, platelets and white blood cells (WBC). Participants were counted in the category that their value changes to (low, normal or high), unless there is no change in their category. The number of participants with data available at the specified data points are represented by n=X in the category titles.
