SGRQ-c is the COPD specific version of SGRQ. It consisted of 40 items in total, corresponding to 3 individual domains (components): symptoms, activity and impact, with different components carrying a different weighting. Component scores were calculated by summing the weights from all positive items in that component, dividing by the sum of maximum possible weights for all items in that component, and multiplying this number by 100. Impact component consisted of questions 8, 10, 11, 13, 14 in Part 2 of the questionnaire. Impact score has the range from 0 to 100. Higher scores indicated more severe disease impact. Day 1 (Pre-dose) was considered as a Baseline. Analysis was performed using ANCOVA model. Change from Baseline was calculated as post-dose visit value minus the Baseline value.
Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1)
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 measurements were collected using a spirometer. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was calculated as post-dose visit value minus the Baseline value.
Change From Baseline in Sniff Nasal Inspiratory Pressure (SnIP)
A bung size-specific to the participant was placed in the nostril deemed to be most patent by the investigator. The participant was asked to make a maximum voluntary sniff effort via a peak flow meter and the greatest effort from 10 repeat measurements were recorded. SnIP was measured in centimeter of water (cm H2O). Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was calculated as post-dose visit value minus the Baseline value.
Clearance (CL) of GSK2881078 Following Oral Dose in Participants
Blood samples were collected at designated timepoints. Pharmacokinetics (PK) parameters of GSK2881078 were calculated using non-compartmental methods.
Volume of Distribution at Steady State (Vss) of GSK2881078 Following Oral Dose in Participants
Blood samples were collected at designated timepoints. PK parameters of GSK2881078 were calculated using non-compartmental methods.
