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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Efficacy as determined by Total Numeric Transformed Modified Ashworth scale (TNmAS) in the most affected limb. | Change from baseline through end of treatment in the pre-dose, morning TNmAS of the most affected limb. The most affected limb is determined at baseline using the sum of scores for three major motor groups. High scores indicate more severe spasticity. | Change in baseline from Visit 1 through Visit 9 (120 days) or end of treatment | |
Primary | Clinical Global Impression of Change (CGIC) through end of treatment | The CGIC is a global rating scale that captures the investigator's assessment of the subject's change in overall functional performance since starting the study. Scores range from -3 (significant worsening) to +3 (significant improvement. | Visit 9 (120 days) or end of study | |
Secondary | Changes in the Multiple Sclerosis Spasticity Scale (MSSS-88) | This MSSS-88 is a self-administered questionnaire for the subject to assess overall functional performance and sense of impairment with respect to the level of spasticity. | Baseline through Visit 9 (120 days) | |
Secondary | Changes in the TNmAS for the most affected limb | The modified Ashworth Scale is a six (6)-point rating scale that measures abnormality in tone or the resistance to passive movements. Measurements are made in three muscle groups of each limb. The most affect limb is determined at baseline, based on the sum of scores from each limb. Higher scores indicate more severe spasticity. | From baseline to visits 4 (22 days), 5 (36 days), 6 (50 days), 7 (71 days), and 9 (120 days) | |
Secondary | Changes in the TNmAS for the sum of all limbs | The sums of scores from all limbs are compared to the baseline sum. Higher scores indicate more severe spasticity. | Baseline to visits 4 (22 days), 5 (36 days), 6 (50 days), 7 (71 days), and 9 (120 days) | |
Secondary | Changes in Expanded Disability Status Score (EDSS) | The EDSS is based on an examination by a neurologist with a scale that ranges from zero (0) to ten (10) in half point (0.5) unit increments. Higher scores represent higher levels of disability. | Baseline to Visit 9 (120 Days) | |
Secondary | Changes in the Lower Extremity Manual Muscle Testing (LEMMT) Scale | The LEMMT Scale is an evaluation of the function and strength of individual muscles and muscle groups based on effective performance of limb movement in relation to the forces of gravity and manual resistance. Maximum muscular strength is the maximum amount of tension or force that a muscle or muscle group can voluntarily exert in one maximal effort. Scores for each muscle or muscle group range from 0 (no detectable activity) to 5 (normal activity). | Baseline to Visit 4 (22 days), Visit 5 (36 days) Visit 6 (50 days) Visit 7 (71 days) and Visit 9 (120 days) | |
Secondary | Changes in Epworth Sleepiness Scale (ESS) | The ESS is used to determine the level of daytime sleepiness. The questionnaire asks the subject to rate his or her probability of falling asleep on a scale of increasing probability from 0 to 3 in eight different situations. | Baseline to Visit 4 (22 days), Visit 5 (36 days) Visit 6 (50 days) Visit 7 (71 days) and Visit 9 (120 days) | |
Secondary | Changes in the subject-recorded mean daily Drowsiness Numerical Rating Scale (DNRS)score for the day prior to each visit | Drowsiness will be reported by the subject using a numerical rating scale with a range of zero (0; no drowsiness) to ten (10; worst possible drowsiness). Scores will be recorded every 3 hours during the day before each designated visit. | Baseline to Visit 4 (22 days), Visit 5 (36 days) Visit 6 (50 days) Visit 7 (71 days) and Visit 9 (120 days) | |
Secondary | Changes in the Urinary Symptom Profile (USP) Scale | The USP is a Health-Related Quality of Life questionnaire composed of 13 items assessing urinary symptoms in adults with stress, urge, overactive bladder, or urinary obstructive symptoms. | Baseline to Visit 4 (22 days), Visit 5 (36 days) Visit 6 (50 days) Visit 7 (71 days) and Visit 9 (120 days) | |
Secondary | Clinical Global Impression of Change (CGIC) | The CGIC scores will be recorded at the designated intervals prior to Visit 9 (end of study) | Baseline to Visit 4 (22 days), Visit 5 (36 days) Visit 6 (50 days) Visit 7 (71 days) |
