Brief Summary

Previous clinical studies of immediate release (IR) formulations of GSK2982772 resulted in a high peak to trough ratio of GSK2982772. Additionally, the short half-life for GSK2982772 (approximately 2 to 3 hours) necessitates twice a daily (BID) or thrice daily (TID) dosing of an IR formulation. As a result, MR formulations using a polymer matrix approach with minitablets in capsule and MR tablet formulations were investigated. The emerging PK data of the MR formulations investigated to date have demonstrated that a once daily (QD) PK profile can be achieved in the fasted state but the polymer matrix formulation is susceptible to food effects when administered with a high fat breakfast. The purpose of this study is to evaluate MR prototype coated tablet formulations. This study will evaluate the PK of MR prototype coated tablet formulations of GSK2982772. The study is divided into two parts; Part A and Part B. The MR tablet coating used in Part A and the initial periods of Part B will have an aperture drilled into the enteric coating of either side of the tablet. This allows some drug release to commence in the stomach whilst providing controlled release throughout the gastrointestinal (GI) tract. In Part B only, a new investigational medicinal product (IMP) will be manufactured to allow comparison of the tablet coating either with apertures (i.e., drilled) or without apertures (i.e., full coat/non drilled). Part A will be a 6-period, 6-way fixed sequence design, up to 4 MR tablet prototype coated formulations will be evaluated in fasted state at 240 milligrams (mg). Periods 1, 2 and 3 will evaluate MR1, IR tablet and MR2 respectively. Periods 4, 5 and 6 will be flexible and the dosing regimen will be dependent on the outcome of Periods 1 to 3. In addition, the impact of food (high fat meal, standard breakfast or administration 30 or 60 minutes before a standard breakfast) on selected MR prototype coated tablet formulations may also be evaluated in Period 4, 5 or 6 of Part A. Each inpatient period for MR regimens (Periods 1, 3, 4 to 6) will consist of 4 days and 3 nights, and the inpatient period for the IR tablet (Period 2) will consist of 3 days and 2 nights. There will be a minimum washout of 7 days between doses, and a follow-up visit will occur at 7 to 9 days after the last study treatment. The Part B of the study will be a 7-period fixed sequence which will evaluate the selected MR prototype coated tablet formulation(s) at different tablet strengths or as multiple unit doses and with or without apertures in the tablet coatings. There will be an interim review after each period 1 to 5 of Part B to select the dose level, formulation and prandial status for each subsequent period. An interim data review after Part B Period 6 will determine if optional Period 7 is required and the dose level, dosing time (morning or evening), formulation and prandial status for that period. Each inpatient period will consist of a 4-day and 3-night with a minimum of 7 days washout between doses. A follow-up visit will occur at 7 to 9 days after the last study treatment. Approximately 33 subjects will be enrolled in the study. The total duration for Part A will be approximately 10-12 weeks and 10-14 weeks for Part B (including screening period of approximately 4 weeks).

Clinical chemistry parameters with PCI values:albumin (low: \<30 millimoles per liter\[mmol/L\]), Alanine transaminase (ALT) (high: \>=2xupper limit of normal \[ULN\]), Aspartate Aminotransferase(AST) (high: \>=2xULN), Alkaline phosphatase(ALP) (high:\>=2xULN), calcium(low: \<2 mmol/L, high: \>2.75 mmol/L),creatinine (high: \>44.2 mmol/L),glucose (low: \<3 mmol/L,high: \>9 mmol/L), potassium (low: \<3 mmol/L,high: \>5.5 mmol/L),sodium (low: \<130 mmol/L,high: \>150 mmol/L),total bilirubin(high :\>= 1.5xULN). Participants are counted in the worst case category that their value changes to (Low, Normal or High), unless there is no change in their category. Participants whose value category was unchanged (e.g., High to High),or whose value became normal, are recorded in the "To Normal or No Change" category. Participants are counted twice if the participants has values that changed 'To Low' and 'To High', so the percentages may not add to 100%. Data for worst-case post-Baseline has been reported.

Part A: Number of Participants With Abnormal Urinalysis Dipstick ResultsDay 2 (post-dose)

Urine samples were collected for analysis of specific gravity, potential of hydrogen ions, glucose, protein, blood and ketones by dipstick method. Microscopic examination was performed abnormal data for red blood cells (RBC): 1-9 High potential field (HPF) and WBC: 1-9/ HPF; WBC: 10-50/HPF has been presented.
