GSK2018682 is a potent and selective agonist for the sphingosine-1- phosphate receptor subtype 1 (S1P1) with the potential to be an effective treatment for multiple sclerosis (MS). The immunomodulatory properties of GSK2018682 are related to functional antagonism of S1P1 on lymphocytes, resulting in sequestration of lymphocytes within the lymphoid organs, rendering them incapable of migrating to sites of inflammation and leading to lymphopenia. Orally administered GSK2018682 is very effective in murine experimental autoimmune encephalomyelitis (EAE), an animal model of human MS. This study will assess the relative bioavailability of different oral formulations of GSK2018682 in healthy volunteers. A tablet formulation is desired for progression into future clinical safety and efficacy studies as the current capsule formulation is not suited to large scale manufacture. The information obtained in this study will help to establish the optimal dosing form for future studies, and also determine the effect of food on the pharmacokinetics of GSK2018682.

Experimental: Oral formulations of GSK2018682
Three oral formulations of GSK2018682. A: CD2 Capsule; B: CD3 non-micronised Tablet; C: CD3 micronised Tablet; D: CD3 non-micronised Tablet in fed state

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • AST, ALT, alkaline phosphatase and bilirubin less than or equal to 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters significantly outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Subjects with lymphocyte counts outside the normal range should always be excluded from enrollment.
  • Male or female between 18 and 55 years of age inclusive, at the time of signing the informed consent.
  • A female subject is eligible to participate if she is of:
  • Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MIU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.
  • Male subjects must agree to use one of the protocol-approved contraception methods. This criterion must be followed from the time of the first dose of study medication until the study follow up visit.
  • BMI within the range 19 - 29 kg/m2 (inclusive).
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • QTcB or QTcF < 450 msec.

Exclusion Criteria:

  • A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • A positive pre-study drug/alcohol screen.
  • A positive test for HIV antibody.
  • History of regular alcohol consumption within 6 months of the study defined as:

An average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 285 ml glass of full strength beer or 425 schooner of light beer or 1 glass (100 ml) of wine or 1 (30 ml) measure of spirits.

  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
  • Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
  • Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
  • History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
  • Pregnant females as determined by positive serum or urine hCG test at screening or prior to dosing.
  • Unwillingness or inability to follow the procedures outlined in the protocol.
