Trial overview

Official title: A phase II, 20-week, multi-centre, randomised, double-blind, placebo-controlled, parallel group proof of concept study to investigate the efficacy and safety of GSK1605786 for treatment of patients with active Ulcerative Colitis
Trial description: GSK1605786 is an oral antagonist specific for the chemokine receptor CCR9 in
development for treatment of small bowel and colonic Crohn’s disease (CD). The
purpose of this Phase II proof of concept study is to investigate the efficacy and safety of
GSK1605786 (500 mg twice daily) administered orally for 16 weeks for the treatment of
patients with active ulcerative colitis (UC).
A key secondary objective is to understand the mechanism by which GSK1605786 is
acting and to this end samples will be collected to confirm the degree of inhibition of
CCR9 on T lymphocytes in the blood of patients, and to explore the relationship between
concentration of drug and changes in lymphocyte and antigen presenting cell populations
in the peripheral circulation and in the colon. Patients recruited at specified
investigational sites will be invited to participate in an optional sub-study to explore the
effects of GSK1605786 on trafficking of technetium labelled T cells using Single Photon
Emission Computerized Tomography (SPECT). Specifically, the technique will be used
to follow trafficking to large intestine and thymus and findings linked to
pharmacokinetics of GSK1605786, receptor occupancy and clinical efficacy outcomes

  • Confirmed diagnosis of celiac disease, those who follow a gluten-free diet to manage
Inclusion and exclusion criteria
Inclusion criteria:
  • Male or female aged 18 and over at the time of signing the informed consent.
  • A female subject of child-bearing potential is eligible to participate if she agrees to use one of the contraception methods listed in Section 8.1 for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until completion of the follow-up visit.
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form, prior to any of the screening procedures including discontinuation of prohibited medication.
  • At screening (visit 1): patients with a clinical history and examination suggestive of active UC for at least 3 months despite at least 2 weeks treatment with oral >2.4g/day mesalazine / mesalamine or equivalent.

    • At screening/randomization (visit 2):

    • Presence of active UC spread beyond the rectum (inflammation extending ≥ 15cm from anal verge) as evidenced by flexible sigmoidoscopy or colonoscopy during the screening window.
    • AND MAYO score of 5 – 10 inclusive.
  • AST and ALT < 2xULN; alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN
Exclusion criteria:
  • If female, is pregnant, has a positive pregnancy test or is breast-feeding.
  • Confirmed diagnosis of celiac disease, those who follow a gluten-free diet to manage symptoms of suspected celiac disease and subjects with positive serologic test for Tissue transglutaminase, tTG.
  • Subjects who have received immunisation with a live vaccine e.g. measles, mumps, rubella (each as in MMR vaccine), oral polio, varicella, yellow fever, within 4 weeks of screening and throughout the study, with the exception of influenza vaccine.
  • Known or suspicion of CD, indeterminate colitis, microscopic colitis, ischaemic colitis or radiation-induced colitis, based on medical history, endoscopy and/or histological findings.
  • Subjects with imminent need for surgery for UC in the opinion of the investigator.
  • Subjects where assessment of MAYO score is likely to be confounded by previous surgery (for example colectomy, ileostomies, colostomies or rectal pouches).
  • Subjects requiring enteral or parenteral feeding.

    • Use of prohibited medications within their specified timeframes (see Section 9).

    • 5-Aminosalicylic acid enema: within 2 weeks of screening and throughout study
