Brief Summary

GSK2269557 is potent and highly selective inhaled phosphoinositides 3-kinases -delta (PI3K-delta) inhibitor being developed as an anti-inflammatory agent for the treatment of inflammatory airway diseases. GSK2269557 has already been administered as a nebulized solution in single and repeat doses to humans and has been well tolerated across the range of doses used. The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of single and repeat inhaled doses of GSK2269557 as a dry powder. This study is the first administration of dry powder GSK2269557 in humans.

Part A will consist of four treatment periods separated by at least 14 days wash out periods. In each treatment period there will be 12 subjects receiving GSK2269557 and 4 subjects receiving placebo. The doses of GSK2269557 planned for Part A are 100 micrograms (mcg), 500 mcg and 3000 mcg. Blinded safety and available pharmacokinetic (PK) data will be reviewed before each dose escalation. Part B will be a parallel group design conducted in a separate group of subjects from Part A. Nine subjects will receive repeat doses of GSK2269557 and 3 subjects will receive repeat doses of placebo for 14 days. The total daily dose will be the same as the dose that was well tolerated in Part A. The study duration, including screening and follow-up, is not expected to exceed 82 days for subjects in part A and 55 days for subjects in part B of the study.

Placebo arm

The subjects will receive single dose of placebo in each treatment period of part A and repeat doses of placebo in Part B of the study.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

Dry powder for oral inhalation once daily using DIKUS device

Part B GSK2269557 arm

The selection of total daily doses of GSK2269557 for Part B will anticipated to be the maximum well tolerated dose selected from Part A. The subjects will receive GSK2269557 in ratio of 3:1.with placebo. If the dose selected for Part B is not well tolerated on repeat dosing the dose may be reduced during Part B or given as divided doses.

Eligibility Criteria

Inclusion Criteria

• Subjects who are current daily cigarette smokers. Must have smoked regularly in the 12-month period preceding the screening visit and have a pack history of >= 5 pack years (number of pack years = number of cigarettes per day/20 x number of years smoked

• Single QTcF < 450 milliseconds (msec); or QTcF< 480 msec in subjects with Right Bundle Branch Block
• Currently healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac testing.
