The purpose of this study is to evaluate specific alterations in immune cell mechanisms related to neutrophil function as detected by PI3Kdelta-dependent changes in messenger ribonucleic acid (mRNA) extracted from induced sputum in patients experiencing an exacerbation of COPD, with or without treatment with GSK2269557. The efficacy of treatment with GSK2269557 will also be measured using functional respiratory imaging (FRI) and spirometry. This is a randomised, double-blind, placebo-controlled, parallel-group study. The study consisted of Screening Phase (up to 3 days prior to Day 1), Treatment Phase (Days 1 to 84) and Follow phase (7 to 14 days after last dose). The total duration of the study is 13-14 weeks including the screening visit. DISKUS TM and ELLIPTA TM are registered trademark of GSK group of companies.

Change in Messenger Ribonucleic Acid (mRNA) Transcriptome in Induced Sputum After 12, 28 and 84 Days of Treatment (Selected Probe Sets With Fold Change >1.5 or <-1.5 and p<0.05) in NEMI Treatment Group
Saline-induced sputum samples were collected at the indicated time-points to determine the alterations in previously identified immune cell mechanisms specifically related to neutrophil function by identifying the changes in mRNA transcriptome in induced sputum. Baseline was defined as screening visit. The log2 transformed mRNA intensities for each probe set were analyzed in a separate repeated measures model. Back transformed baseline-adjusted ratios and two-sided unadjusted p-values were calculated for each visit as the specified time-point value/baseline value. These ratios were converted to fold change values; if ratio \>= 1 then fold change=ratio or if ratio \< 1 then fold change = -1/ratio. Data for pre-specified probe sets that meet the criteria fold change \>1.5 or \<-1.5 and p\<0.05 for All NEMI, All Placebo and All NEMI/All Placebo group is presented in outcome measure 1, 2 and 3 respectively. In the categories column we have included time-point, Probe ID and Gene label.

Saline-induced sputum samples were collected at the indicated time-points to determine the alterations in previously identified immune cell mechanisms specifically related to neutrophil function by identifying the changes in mRNA transcriptome in induced sputum. For each probe set, the log2 transformed mRNA intensities were analyzed in separate repeated measures models. The models included a Treatment, Visit and Treatment\*Visit term. The Visit consisted of 4 levels: Screening (Baseline), Day 12, Day 28 and Day 84, and the Treatment consisted of three levels: Null (when Visit = Screening), All Placebo and All NEMI. The fold changes were derived from the back transformed ratio from Baselines as fold change = ratio if ratio is \>=1, else if ratio \<1 then fold change = -1/ratio. Data for pre-specified probe sets that meet the criteria fold change \>1.5 and p\<0.05 for All NEMI, All Placebo and All NEMI/All Placebo group is presented in outcome measure 1, 2 and 3 respectively.
