ClinicalTrials.gov Identifier:
NCT01036022

  Purpose

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.

  • Mean Treatment Effects on Basal Morning Cortisol and Adrenocorticotropic Hormone (ACTH) Stimulated Cortisol Levels at Week 4 in Comparison With Baseline [ Time Frame: Baseline (Day 1, pre dose) and Week 4 ]
    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.

  • Mean Concentration of GSK1399686 in Colon Biopsy Obtained Within 24 h After the Last Dose [ Time Frame: Week 4 ]
    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.


Secondary Outcome Measures:
  • Mean Simple Clinical Colitis Activity Index (SCCAI) Score [ Time Frame: Up to Week 6 ]
    SSCAI included composite score: bowel frequency during day on a scale of 0-3 defined as 0 was <= 3, 1= 4 to 6, 2= 7 to 9 and 3 was > 9, during night on a scale of 0-2 defined as 0= none, 1=1 to 3 and 2 was >=4, defecation urgency on a scale of 0-3 defined as 0=none, 1=hurry, 2=immediately and 3=incontinence, blood in stool on a scale of 0-3 defined as 0= none, 1= trace, 2= occasionally frank and 3= usually frank, general well being on a scale of 0-4 defined as 0=very well, 1= slightly below par, 2= poor, 3 = very poor and 4= terrible, extracolonic features (arthritis, pyoderma gangrenosum, erythema nodosum, uveitis) on a scale of 0-1 defined as 0= absent, 1= present. The SCCAI score was calculated as a sum of scores for each individual component of the SCCAI. Minimum score 0, maximum score 19. Higher score implied worsening of symptoms. Participants were given a diary to score each component of SCCAI each morning. Average SCCAI scores over last 3 days were used for each Week.

  • Number of Participants With Clinical Response and Clinical Remission at Week 4 and Week 6 [ Time Frame: Week 4 and Week 6 ]
    Participants were defined as clinical responders if the average change from baseline total SCCAI score was <-2. (i.e. the post dose total SCCAI score was decreased by >2 points compared to the baseline total SCCAI score). Baseline was defined as the value on Day -1. The change from baseline total SCCAI score was derived by subtracting the baseline value (Day -1) from the individual post-dose values. Participants were defined as in clinical remission if the post dose total SCCAI score was <3 and baseline SCCAI score was not <3 (i.e . =>3).

  • Median Time to Clinical Response and Clinical Remission [ Time Frame: Up to Week 6 ]
    Time to clinical response was defined as the number of days between first dose of study medication and first day of at least 3 consecutive days with SCCAI score decreased for >2 points in comparison with baseline (Day -1 value). Time to clinical remission was defined as the number of days between the first dose of study medication and the first day of at least 3 consecutive days with SCCAI score < 3. Time to clinical response and remission was derived using daily diary data. Participants who did not meet the criteria for clinical response or clinical remission were censored at their last day on study medication.

  • Mean Fecal Calprotectin Levels Over Time [ Time Frame: Up to Week 6 ]
    Fecal calprotectin, a non-invasive surrogate marker of inflammation in the small intestine, and levels of which was associated with mucosal healing. Calprotectin is a calcium and zinc-binding protein found in neutrophils, monocytes and macrophages. Calprotectin is produced in significant amounts by inflammatory cells. Fecal levels of this protein has been demonstrated to correlate with colorectal and intestinal inflammation. Calprotectin plays a regulatory role in the inflammatory process and used as a diagnostic biomarker. It was assessed from Week 1 to Week 6.

  • Mean Fecal Lactoferrin Levels Over Time [ Time Frame: Up to Week 6 ]
    Fecal lactoferrin, a non-invasive surrogate marker of inflammation in the small intestine, and levels of which was associated with mucosal healing. Lactoferrin is an iron binding glycoprotein that is the major component of the secondary granules of polymorphonuclear neutrophils (but not monocytes and lymphocytes). Lactoferrin is produced in significant amounts by inflammatory cells. Fecal levels of this protein has been demonstrated to correlate with colorectal and intestinal inflammation. Lactoferrin plays an important role in the innate immunity as a bactericidal and used as a diagnostic biomarker. It was assessed from Week 1 to Week 6.

  • Mean Maximum Observed Concentration (Cmax) on Day 1 and Day 28 Derived From Observed Plasma Concentrations of GSK1399686 After Repeated Oral Dosing [ Time Frame: Day 1 (1 hour, 2 hour, 3 hour post dose) and Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose) ]
    Cmax was derived on Day 1 and Day 28 from observed plasma concentrations of GSK1399686 after repeated oral dosing. Blood samples were collected on Day 1 (1 hour, 2 hour, 3 hour post dose) and Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose).

  • Pre-dose Trough Concentration at the End of the Dosing Interval (Cτ) on Day 28 Derived From Observed Plasma Concentrations of GSK1399686 After Repeated Oral Dosing [ Time Frame: Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose) ]
    Cτ was derived on Day 28 from observed plasma concentrations of GSK1399686 after repeated oral dosing. Blood samples were collected on Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose).

  • Plasma Clearance Estimated Based on Population Pharmacokinetic Analysis of Healthy Volunteers (Historical Data) and Patient Data [ Time Frame: Day 1 (1 hour, 2 hour, 3 hour post dose), Week 1 (anytime relative to the last dose), Week 2 (anytime relative to the last dose) and Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose) ]
    Clearance derived from plasma concentration-time data was planned to be combined with data from healthy volunteers from Phase I study to characterize the population pharmacokinetics of GSK1399686. However data for this outcome measure was not collected.

  • Volume of Distribution Estimated Based on Population Pharmacokinetic Analysis of Healthy Volunteers (Historical Data) and Patient Data [ Time Frame: Day 1 (1 hour, 2 hour, 3 hour post dose), Week 1 (anytime relative to the last dose), Week 2 (anytime relative to the last dose) and Day 28 (Week 4 at pre dose, 1 hour, 2 hour, 3 hour and 4 hour morning post dose) ]
