Eligibility
Key inclusion criteria
Inclusion criteria:

- Written informed consent

- Males or females, aged 18 to 65, inclusive

- A diagnosis of relapsing-remitting MS [Polman, 2005; McDonald, 2001] with
dissemination in time and space

- EDSS of between 0 and 6.0 inclusive at the Screening visit

- Occurrence of at least two relapses in previous 24 months with at least one relapse or
documented evidence of gadolinium-enhancement on MRI (prior to screening) in the
previous 12 months. Subject must not have had a relapse within 4 weeks prior to
Screening. In addition, subjects experiencing a relapse between Screen and Visit 3
will not be eligible to be randomized.

- A minimum of five T2 lesions on brain MRI at Visit 2 as determined by the central MRI
analysis reader

- A female subject is eligible to enter the study if she is:

- Of non-childbearing potential, i.e. women who:

- have documented evidence of tubal ligation, bilateral oophorectomy or
hysterectomy; or

- are post-menopausal, defined as at least one year without menses in the absence
of hormone replacement therapy. In questionable cases, menopausal status will be
confirmed by oestradiol and FSH levels consistent with menopause according to
local laboratory ranges. Oestrogen-containing hormone replacement therapies are
not allowed during the study.

- Of childbearing potential, has a negative urine pregnancy test at Screening, and
agrees to the consistent and correct use of one of the methods of contraception
listed below. Subjects will use this contraceptive method for at least one month
prior to Screening and should continue to use the same contraceptive method
throughout the study until at least 3 days after the last dose of investigational
product.

- Progesterone-only oral contraceptives or implants (inserted at least one month
prior to Screening, but not beyond the third successive year following
insertion). Oestrogen-containing contraceptives are not allowed during the study.

- Intra-uterine device (IUD) inserted by a qualified clinician. The IUD must have
published data showing that the highest expected failure rate is less than 1% per
year.

- Spermicide in conjunction with either a diaphragm, cervical cap or condom. Male
partner sterilization (vasectomy) prior to female subject's entry into the study
and is the sole partner for that female subject

- In France, a subject will be eligible for inclusion in this study only if either
affiliated to or a beneficiary of a social security category.
Minimum age
18 Years
Maximum age
65 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Subjects receiving corticosteroids within 4 weeks of Screening for treatment of MS. If
non-systemic steroids are being used for other chronic inflammatory conditions,
subjects may be included at the discretion of the investigator after discussion with
the GSK medical monitor

- Use of an b-interferon product, glatiramer acetate or azathioprine within 3 months of
Screening, or use of Mitoxantrone within 12 months of Screening. Subjects who have
received other therapies affecting the immune system (such as intravenous
immunoglobulin (IVIg), cyclophosphamide, plasmapheresis, or any other
immunosuppressive or immunomodulatory treatment) in the past may be included on a case
by case basis after discussion with the GSK medical monitor. None of these treatments
will be allowed during this study

- Previous exposure to alemtuzumab, natalizumab or firategrast administration, bone
marrow transplantation or whole body irradiation

- Subjects with a cardiac pacemaker or any other type of metal implant or with any other
contraindication for MRI (including known allergy to gadolinium)

- Use of 4-aminopyridine, rosiglitazone, pioglitazone or any drug that is an inhibitor
of or a substrate (with a low therapeutic index) for OATP at Screening.

- Subjects with clinically significant renal laboratory values: subjects with a
calculated creatinine clearance <60ml/min (by Cockcroft and Gault) at Screening

- Subjects with local urinalysis findings of 1) proteinuria, defined as =1+ protein, on
urine dipstick or 2) renal tubular cell casts or 3) =5 red blood cells / high power
field will be excluded from the study if the result is still present on a repeat
urinalysis during the screening period.

- Presence of clinically significant hepatic laboratory values: ALT, AST, GGT > 2.0-
times the upper limit of normal (ULN); total bilirubin > 1.5 times the ULN at
Screening

- CD4 count <500, CD4:CD8 <1.0 (if result still present on a repeat test during the
screening period), JC viremia detected in plasma or white cells, idiopathic CD4/CD8
lymphopenia or secondary lymphopenia at Screening

- Any findings on the MRI of the brain at Visit 2 other than MS, except for benign
findings that (in the opinion of the central MRI reading site and local site
investigator) require no further evaluation or treatment and do not impact patient's
neurological health (e.g., small arachnoid cysts, venous angiomas)

- Current or history of cancer, excluding localized non-melanoma skin cancer

- Uncontrolled or any active bacterial, viral, or fungal infection at Screening. Any
previous serious infections should be discussed with the GSK medical monitor (e.g.
opportunistic or atypical infections)

- History of tuberculosis (TB) or positive chest X-ray for TB at Screening (prior chest
X-ray is acceptable if performed within previous 6 months)

- Known congenital or acquired immunodeficiency

- Any abnormality on 12-lead ECG at Screening which is clinically significant in the
opinion of the investigator

- Subjects with positive hepatitis B surface antigen, hepatitis C antibody, or HIV tests
at Screening

- Women who are lactating, pregnant (positive pregnancy test at Screening), or planning
to become pregnant during the course of the study

- Recent history or suspicion of current drug abuse (including analgesic abuse) or
alcohol abuse within the last 6 months prior to Screening

- Use of an investigational drug for condition other than MS within 30 days or five
half-lives (whichever is longer) preceding Screening. Prior use of an investigational
drug for MS should be discussed with the GSK medical monitor

- Any concurrent illness, disability or clinically significant abnormality (including
laboratory tests) that may affect the interpretation of clinical efficacy or safety
data or prevent the subject from safely completing the assessments required by the
protocol

Summary
Brief summary
SB-683699 is an oral medication that is thought to reduce the number of active white blood
cells entering the brain; these white blood cells are part of the disease process for MS.
This study will look at whether different doses of SB-683699 are effective and safe in
patients with relapsing remitting MS.
