GSK2982772 Study in Subjects With Ulcerative Colitis

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.

    Time frame: Baseline and Day 43

    Geboes score is a 7-items instrument which classifies histologic changes and generates a score from 0 to 5.4. The 7 items are: grade 0=structural-architectural changes (scored from 0.0 to 0.3); grade 1=chronic inflammatory infiltrate (scored from 1.0 to 1.3); grade 2A=lamina propria neutrophils (scored from 2.0 to 2.3), grade 2B= lamina propria eosinophils (scored from 2.0 to 2.3); 3=neutrophils in the epithelium (scored from 3.0 to 3.3); 4=crypt destruction (scored from 4.0 to 4.3); 5=erosions or ulceration (scored from 5.0 to 5.4). The most severe observation that the histopathologist sees on the slide is considered as the Geboes index total score, ranges from 0 to 5.4, with higher scores indicates severe disease. BL is defined as the latest pre-dose assessment before Day 1. Change from BL is the value at indicated time point minus BL value.
