Overview
Brief Summary
This first time in human (FTIH) study assesses the safety, tolerability, and pharmacokinetics (PK) of single and multiple increasing doses of GSK2556286. It also includes food effect cohorts to evaluate how food influences the PK of GSK2556286. The findings will help determine appropriate dosing for future clinical studies.

Arms & Interventions
Part A: Participants receiving GSK2556286
Participants will be randomized to receive GSK2556286 in any of the 11 cohorts. In each dosing cohort, 6 participants will receive a single dose of GSK2556286. Following initial dosing of cohorts in the fasted state, one cohort will investigate the effect of food administration (high fat meal) on safety, tolerability and PK data of GSK2556286. One cohort may also investigate the effects of a moderate fat meal.
Intervention: GSK2556286
Part A: Participants receiving placebo
Participants will be randomized to receive matching placebo in any of the 11 cohorts. In each dosing cohort, 2 participants will receive a single dose of matching placebo.
Intervention: Placebo
Part B: Participants receiving GSK2556286
Participants will be randomized to receive GSK2556286 in any of the 4 cohorts. In each dosing cohort, 6 participants will receive repeat doses of GSK2556286 under either fasting or fed conditions, dependent on the results from Part A. Appropriate doses and dose regimens for Part B will be selected by the Dose Escalation Committee based on available safety, tolerability and PK data from Part A and/or any preceding repeat dose cohorts from Part B.
Intervention: GSK2556286
Part B: Participants receiving placebo
Participants will be randomized to receive matching placebo in any of the 4 cohorts. In each dosing cohort, 2 participants will receive repeat doses of matching placebo under either fasting or fed conditions, dependent on the results from Part A.
Intervention: Placebo
