Brief Summary:
This study is the first experience with GSK2982772, a receptor-interacting protein-1 (RIP1) kinase inhibitor, in subjects with active ulcerative colitis (UC). The primary objective will be to investigate the safety and tolerability of repeat oral doses of GSK2982772 60 mg or placebo three times daily for 42 days (Part A) followed by open label with GSK298772 60 mg three times daily for 42 days (Part B). In addition to pharmacokinetics (PK), a number of experimental and clinical endpoints will be employed to obtain information on the pharmacodynamics (PD), and preliminary efficacy in subjects with active UC. Although no formal hypothesis will be tested, these endpoints will enable a broader understanding of the mechanism of action and potential for clinical efficacy of GSK2982772 in UC. Within 30 Days of screening visit, subjects will be randomized to receive either GSK2982772 60 mg or placebo orally three times daily for 42 Days (6 weeks) in a 2:1 ratio in Part A study. Subjects who complete the Part A study will move to open label Part B study to receive GSK2982772 60 mg three times daily for an additional 42 Days (6 weeks). After the open label (Part B) treatment period, subjects will enter the Follow-up period which lasts for 28 Days (+/- 3 Days) post the last administration of study medication. The total duration of participation in the study will be approximately 20 Weeks from screening to the last study visit.

Secondary Outcome Measures :
  1. Number of subjects who achieve an absolute Mayo endoscopy subscore of 0 or 1 [ Time Frame: Up to Day 85 ]
    The Mayo Score is a 12-point scoring system used to assess UC disease activity based on stool frequency, rectal bleeding, endoscopic appearance and Physician's Global Assessment of Disease (PGA). A partial Mayo Score is a scoring system where disease activity is evaluated based on stool frequency, rectal bleeding and physician global assessment, without endoscopic components. Total and Partial Mayo Scores will be collected and scored centrally. The scores will be rated as normal if score is 0, mild if score is 1, moderate if score is 2 and severe if score is 3. Number of subjects who achieve an absolute Mayo endoscopy subscore of 0 or 1 at Days 43 (Week 6) and 85 (Week 12) will be reported.

  2. Change from Baseline in mucosal appearance determined by Ulcerative Colitis Endoscopic Index of Severity (UCEIS) [ Time Frame: Baseline and up to Day 85 ]
    UCEIS will be used as an additional tool to assess disease activity based on endoscopic vascular pattern, bleeding, erosions and ulcerations. It has been shown to accurately predict overall assessment of endoscopic severity of UC. The UCEIS is a scoring system UCEIS will be collected and scored centrally. Baseline is the value at pre-dose on Day 1.

  3. Change from Baseline in the marker, mean CRP [ Time Frame: Baseline and up to Day 118 ]
    A blood sample will be taken as part of the chemistry laboratory sample to measure CRP.

    A fecal sample will be taken to measure FCP.

  5. Change from Baseline in histologic severity assessed by Modified Riley Score (MRS) [ Time Frame: Baseline and up to Day 85 ]
    The MRS is a 4 point scale (none, mild, moderate and severe) which scores histologic activity based on localization and quantification of neutrophils in the mucosa. Score is rated as none if score is 0, mild if score is in the range of 1 to 3, moderate if score is in the range of 4 to 6, severe if score is 7.

  6. Change from baseline in histologic severity assessed by Geboes Index [ Time Frame: Baseline and up to Day 85 ]
    Upon scoring of all components of the index, the highest grade with a subgrade above 0 will be recorded as a histological score.

  7. Number of subjects who achieve clinical response [ Time Frame: Up to Day 85 ]
    Clinical response is defined as reduction by >=3 points or >=30 percent improvement from Baseline complete Mayo score, along with a decrease in the rectal bleeding score of >=1 point, at Days 43 (Week 6) and 85 (Week 12).

  8. Number of subjects who achieve clinical remission [ Time Frame: Up to Day 85 ]
    Clinical remission is defined as a complete Mayo score of 2 points or lower, with no individual subscore exceeding 1 point, at Days 43 (Week 6) and 85 (Week 12).

  9. Change from Baseline in partial Mayo score [ Time Frame: Baseline and up to Day 85 ]
    A partial Mayo Score is a scoring system where disease activity is evaluated based on stool frequency, rectal bleeding and physician global assessment, without endoscopic components. Partial Mayo Scores will be collected and scored centrally. The scores will be rated as normal if score is 0, mild if score is 1, moderate if score is 2 and severe if score is 3.

  10. Measurement of pre-dose plasma concentrations of GSK2982772 [ Time Frame: Day 43 ]
    Pre-dose blood sample will be drawn on Day 43 for the measurement of plasma concentration of GSK2982772.

  11. Measurement of post-dose plasma concentrations of GSK2982772 [ Time Frame: 1, 2, 4 and 6 hours on Day 1 and Day 43 ]
    Post-dose blood sample will be drawn on Days 1 and 43 at 1, 2, 4 and 6 hours for the measurement of plasma concentration of GSK2982772.

  12. Measurement of trough concentrations of GSK2982772 [ Time Frame: Day 85 ]
