Brief Summary:
This study is the first administration of GSK2983559, a selective receptor interacting protein 2 (RIP2) kinase inhibitor, to humans. This will be randomized, double-blinded (sponsor open) and two part study (A and B). Part A of the study is single ascending dose crossover design with two separate cohorts (1 and 2). In Part A, 9 single dose levels will be explored. In Cohort 1, 10 healthy subjects will randomized to receive single oral doses of either GSK2983559 or placebo in a ratio of 4:1 in 5 way cross-over design with 5 treatment periods. In Cohort 2, 8 healthy subjects will be randomized to receive single oral doses of either GSK2983559 or placebo in a ratio of 3:1 in 4 way cross-overs design with 4 treatment periods. In Cohort 2 there will be an additional period (period 5-open label) for assessing GSK2983559 under fed conditions. There will be 48 hours wash-out period between each dose escalation period. Part B is repeat ascending dose sequential group design. It will contain 4 Cohorts of and dosing will be done sequential dosing. Subjects in Part B will receive once daily (QD) dose or twice daily dose (will be decided based upon the pharmacokinetic, safety and tolerability observed in Part A). There will 58 subjects involved in this study. Total duration of Part A will be approximately for 11 Weeks and Part B will be approximately for 15 Weeks.

  • History or presence of/significant history of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study treatment; or interfering with the interpretation of data.
  • History or current evidence of febrile seizures, epilepsy, convulsions, significant head injury, or other significant neurologic conditions.
  • History of clinically significant psychiatric disorders as judged by the investigator.
  • Any history of suicidal behavior within the past 6 months or any history of attempted suicide in a subject's lifetime.
  • ALT >1.5x upper limit of normal (ULN).
  • Bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • History of Gastrointestinal (GI) surgery (with exception of appendectomy)
  • Average QTc > 450 millisecond (msec)
  • Intended use of over-the-counter or prescription medication including herbal medications within 7 days prior to dosing
  • Live or attenuated vaccine(s) within 30 days of randomization, or plans to receive such vaccines during the study or plans to receive a vaccine within 30 days + 5 half-lives of the last dose of study medication.
  • Regular alcohol consumption within 6 months prior to the study defined as: An average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol: a half pint (approximately 240 milliliter [mL]) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
  • Current use or history of regular tobacco- or nicotine-containing products within 6 months prior to screening. Subject must have urinary cotinine levels indicative of non-smoking status at screening visit.
  • Exposure to more than 4 new chemical entities within 12 months prior to the first dosing day.
  • Current enrollment or past participation within the last 30 days before signing of consent in this or any other clinical study involving an investigational study treatment or any other type of medical research.
  • Subjects with impaired renal function defined as Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) calculation <= 60 milliliter per minute per 1.73 meter square (mL/min/1.73 m^2) estimated by the CKD-EPI equation.
  • An elevated C-reactive protein (CRP) outside of the normal reference range.
  • Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment. As potential for and magnitude of immunosuppression with this compound is unknown, subjects with presence of hepatitis B core antibody (HBcAb) should also be excluded. Subjects positive for HBsAg and/or positive for anti-HBc antibody (regardless of anti-HBs antibody status) are excluded.
  • A positive pre-study drug/alcohol screen.
  • A positive test for HIV antibody.
  • A positive diagnostic TB test at screening defined as a positive QuantiFERON-TB Gold test or T-spot test. In cases where the QuantiFERON or T-spot test is indeterminate, the subject may have the test repeated once, but they will not be eligible for the study unless the second test is negative. In cases where the QuantiFERON or T-spot test is positive, but a locally-read follow up chest x-ray, shows no evidence of current or previous pulmonary tuberculosis, the subject may be eligible for the study at the discretion of the Investigator and GSK Medical Monitor.
  • Sensitivity to any of the study treatments, or components thereof, or drug or other allergy that, in the opinion of the Investigator or GSK Medical Monitor, contraindicates participation in the study.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56-day period.
  • Part A (Food Effect) Cohort: Subject must have no dietary restrictions (e.g., lactose intolerance) or inability to eat a high fat meal.
