Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicenter, randomized (1:1:1), double-blind, active and placebo controlled, parallel group study to evaluate safety, tolerability and efficacy of oral arbaclofen in MS patients with spasticity.

Eligible subjects will be removed from anti-spasticity medications for at least one week and then begin study drug treatment with daily doses increasing up to the target dose which will then be maintained for at least 12 weeks. A down-titration will then occur over two weeks.

* Absence of infections, peripheral vascular disease, painful contractures, advanced arthritis, or other conditions that hinder evaluation of joint movement
* Have a creatinine clearance, as calculated by Glomerular Filtration Rate using the Modification of Diet in Renal Disease (MDRD) Study equation, greater than 60mL/min.
* Use of a medically highly effective of birth control during the study and for ninety (90) days thereafter for women of child-bearing potential (including female subjects and female partners of non-sterile male subjects)
* Willing to allow his or her general practitioner and consultant, if appropriate, to be notified of participation in the study

Exclusion Criteria

* Current malignancy or history of malignancy that has not been in remission for more than five (5) years, except effectively treated basal cell skin carcinoma
* Any other significant disease, disorder or significant laboratory finding which, in the opinion of the investigator, put the subject at risk because of participation, influence the result of the study, or affect the subject's ability to participate
* Planned elective surgery or other procedures requiring general anesthesia during the study
* Subject who is inappropriate for placebo medication in the judgment of the Investigator
