Brief Summary

This study is the first-time-in-patient trial of GSK1399686, a novel locally-acting anti-inflammatory compound, aimed at obtaining initial information on the tolerability, safety, pharmacokinetics (including concentrations in colon mucosa) and anti-inflammatory activity of GSK1399686 upon oral dosing in patients with active ulcerative colitis. The study is designed as a randomized, double-blind, double-dummy, placebo-controlled, sequential dose escalating trial, with an active control (ASACOL) group as internal control. Up to three cohorts (Cohorts 1-3), each consisting of approximately 20 patients with mild-moderately active ulcerative colitis not limited to the rectum, will be included, one for each dose level of GSK1399686 to be tested. Within a cohort, patients will be randomized in a 3:1:1 ratio to receive GSK1399686 (once daily over 4 weeks, followed by 2 weeks dosing with placebo), placebo, or ASACOL (t.i.d. for 6 weeks), respectively. An interim analysis of fecal markers and disease activity data will be performed by the end of Cohort 3. Based upon results, the study may be stopped or continued by recruiting either Cohort 4 (if data on an additional dose level would be warranted to establish or clarify a dose-response relationship) or, in the case of a robust efficacy signal at any dose level previously studied, Cohort 5 (to expand the sample size for given dose level in order to evaluate the efficacy of GSK1399686). The number of patients and randomization allocation ratio may be altered in Cohort 5 and it may not include an active control arm. If Cohort 4 is initiated upon interim analysis, then a second interim analysis may be performed at the end of Cohort 4, to assess whether progression into Cohort 5 (as defined above) would be justifiable.

  Screening (Day -7 to -1), Week 2, 4 and 6

• Mean Treatment Effects on Basal Morning Cortisol and Adrenocorticotropic Hormone (ACTH) Stimulated Cortisol Levels at Week 4 in Comparison With Baseline

  Treatment effects was assessed using a low-dose ACTH stimulation test which was performed on Day 1 pre dose (Baseline) and at Week 4 visit. A blood sample for plasma cortisol was taken immediately, before and 30 minutes after an intravenous injection of 1 microgram (μg). tetracosactide acetate, a synthetic peptide displaying the same physiological properties as ACTH. The change from morning basal cortisol was calculated for Day 1 pre-dose (ACTH1) and Week 4 (ACTH2) using the equation: ACTH1 = Day 1 post ACTH - Day 1 pre ACTH; ACTH2 = Week 4 post ACTH - Week 4 pre ACTH. The change from morning basal cortisol between Week 4 and Day 1 (ACTH effect) was calculated as : ACTH effect = ACTH2 - ACTH1. The difference in morning basal cortisol between Week 4 and Day 1 (ACTH morning) was calculated as:- ACTH morning = Week 4 pre ACTH - Day 1 pre ACTH. Adrenocorticol function was classed as normal if the change from post ACTH to pre ACTH (using ACTH1 and ACTH2) was \>= 200 nanomoles per liter.

  Baseline (Day 1, pre dose) and Week 4

• Mean Concentration of GSK1399686 in Colon Biopsy Obtained Within 24 h After the Last Dose

  The assessment was done on the samples collected from the sigmoid colon and from the rectum obtained within 24 hour after the last dose on Week 4 visit after endoscopic evaluation of respective area for determination of GSK1399686 concentration. Non-quantifiable (NQ) concentration values were imputed as 0.
