Brief Summary

This is a randomized, parallel group, placebo-controlled study designed to assess whether GSK239512 can enhance lesion remyelination in subjects with Relapsing Remitting Multiple Sclerosis (RRMS). Subjects with RRMS on stable background treatment with either Avonex (Interferon-beta1a) or Copaxone (Glatiramer Acetate) are eligible to participate. Subjects will be randomized in a 1:1 ratio between placebo and GSK239512, and will continue to be managed with their current standard of care therapy (Copaxone or Avonex). The total treatment period is 48 weeks, including a standard 4 week titration period and 44 week maintenance treatment period (which could be adapted to a 5-week titration and 43 week maintenance period, if needed). Titration doses start at 10 micrograms (mcg) and increase up to 80 mcg (10 mcg first week, 20 mcg second week, 40 mcg third week, 80 mcg fourth week). Subjects will be titrated to the maximum tolerated dose with the objective of titrating to the highest dose (80 mcg GSK239512), whenever possible, based on investigator judgement of tolerability. The post-treatment follow-up period will be a minimum of 2 weeks in duration following the end of treatment at Week 48 or early withdrawal, as appropriate.

Non-interventional study participation is allowed if the time involvement and scheduling will not interfere with compliance in this study in the opinion of the investigator
• A female subject is eligible to enter the study if she is a) Not pregnant or nursing, b) Of non-childbearing potential (i.e. women who have had a hysterectomy, are postmenopausal, which is defined as >2 years without menses [female subjects who have been post-menopausal for <2 years must be confirmed with Follicle Stimulating Hormone and estradiol levels], have both ovaries surgically removed or have current documented tubal ligation); or, c) Of childbearing potential and agrees to use the acceptable methods of birth control, for one month prior to the start of investigational product to 1 month after the last dose of investigational product.
• Informed Consent: Must be competent to understand the information given in the Institutional Review Board (IRB) or Independent Ethics Committee (IEC) approved Informed Consent Form (ICF) and must sign the form prior to the initiation of any study procedures

Exclusion Criteria

• MRI: Unable to undergo MRI scans (e.g. due to pacemaker, severe claustrophobia, hypersensitivity to contrast media), Lacks adequate venous access for administration of Gd-enhancing agent, or Findings on brain MRI scan indicating any clinically significant brain abnormality other than MS (e.g. damage associated with prior traumatic brain injury)
• Past and Concurrent Medical Conditions: a) History of severe and clinically significant CNS trauma with current sequelae (e.g. traumatic brain injury, spinal cord compression), b) Significant concurrent, uncontrolled medical condition or disease which in the opinion of the investigator could (e.g. significant psychiatric disorder, etc), affect the subjects' safety, impair the subject's reliable participation in the trial, impair the evaluation of the endpoints, or necessitate the use of medication not allowed by this protocol, c) History or presence of myelopathy due to spinal cord compression by disk or vertebral disease or chronic progressive myelopathy, d) Diagnosis of any type epilepsy, e) At risk of suicide, as indicated by: A documented history of attempted suicide or significant suicidal ideation during the 6 months preceding the screening visit, OR If in the investigator's judgment the subject is at risk of a suicide attempt based on the screen visit assessment, including the eC-SSRS, f) Presence of significant and routine sleep disturbance (severe insomnia, nocturnal wandering, confusion, disorientation, agitation, or vivid dreams) that has a negative impact on quality of life that, in the judgement of the investigator, may increase the risk of tolerability issues during dose escalation, g) Presence or history of hallucinations that, in the judgement of the investigator, may increase the safety risk to the subject, h) Known diagnosis or history consistent with positive human immunodeficiency virus (HIV)
