Current Primary Outcome Measures (submitted: March 7, 2018)

Timed 25 foot walk (T25FW, feet/second) [ Time Frame: 12 weeks ]

The T25FW is a measure of lower extremity function. The subject is directed to a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The task is immediately administered again by having the subject walk back the same distance. The result is reported as time to complete (seconds) or speed (feet per second). Improvement is indicated by a decrease in time or an increase in speed.

• Original Primary Outcome Measures (submitted: February 12, 2018): Efficacy of ADS-5102 in subjects with multiple sclerosis with walking impairment as measured by the T25FW, feet/second at Week 12 [ Time Frame: 12 weeks ]

Current Secondary Outcome Measures (submitted: March 7, 2018)

• Timed Up and Go (TUG) [ Time Frame: 12 weeks ]
  The TUG is a measure of lower extremity strength, balance, and coordination. The subject stands up from a chair, walks 3 meters then turns around and walks back to the chair to sit down. The result is reported in seconds. Improvement is indicated by negative change scores.
• 2-Minute Walk Test (2MWT) [ Time Frame: 12 weeks ]
  The 2MWT is a measure of lower extremity function. The subject is instructed to walk as far as possible in 2 minutes, and the distance is measured in meters. Improvement is indicated by positive change scores.
• Multiple Sclerosis Walking Scale-12 (MSWS-12) [ Time Frame: 12 weeks ]
  The MSWS-12 is a 12-item walking scale that is a measure of subject-reported walking ability during the past 2 weeks. Each item is scored on a 1 to 5 scale. A total score can be generated and transformed to a 0 to 100 scale. Improvement is indicated by negative change scores.

• Current medication regimen must be stable for at least 30 days prior to screening, and subject must be willing to continue the same dosing regimen for the duration of study participation
• Maximum Expanded Disability Status Scale (EDSS) score during screening of 6.5
• Stable physical activity level (inclusive of prescribed physical therapy) for at least 30 days prior to screening and willing to continue without change for the duration of study participation

Exclusion Criteria:

• Documented inability to tolerate amantadine
