Intervention model description: This study will consist of two parts; Part A and Part B. Part A will be a 3-way crossover design and Part B will be a sequential-group design.
Primary purpose: TREATMENT

Brief summary: This study is designed to evaluate the safety, tolerability and PK of GSK2982772, in repeat oral doses in healthy subjects. This study is being conducted to support administration of higher dose levels of GSK2982772 than initially studied in the First Time in Human (FTiH) study. This study will also assess the impact of food during the repeat doses of GSK2982772. This will be a two part study; Part A and Part B. Part A (cohort 1) - single ascending dose, randomized, placebo-controlled, 3-way crossover. Part B (cohorts 2, 3, 4 and 5) - repeat dose, randomized, placebo-controlled, sequential-group. Subjects will be randomized in 3:1 ratio to receive GSK2982772 or placebo in crossover manner on Day 1 of each of the three periods in Part A. Subjects will be randomized in 3:1 ratio to receive GSK2982772 or placebo in sequential groups for 14 days in cohort 2 of Part B and in 9:5 ratio to receive GSK2982772 or placebo in sequential groups for 14 days in cohorts 3, 4 and 5 of Part B. Approximately 66 subjects will be included in this study. The study duration, including screening and follow-up, will not be expected to exceed 13 weeks for Part A and 8 weeks for Part B.

A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator in consultation with the Medical Monitor (if required) agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
