Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. 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. 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.

  3. 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.

  • Male or female subjects between 18 and 70 years of age, inclusive, at the time of Screening
  • Confirmed diagnosis of MS according to the 2017 McDonald criteria
  • 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
  • A score on each of two completed screening T25FW tests between 8 and 45 seconds, inclusive

Exclusion Criteria:

  • Documented inability to tolerate amantadine
  • Clinically significant MS relapse with onset less than 30 days prior to screening
  • Receipt of dalfampridine (or any 4-aminopyridine or 2,4-diaminopyridine preparation) or amantadine within 30 days prior to screening
  • History of seizures within 3 years prior to screening
  • History of hallucinations (visual, auditory, or any other type) within 3 years prior to screening
  • History of bipolar disorder, schizophrenia, or psychosis, regardless of treatment
  • For subjects with a history of major depressive disorder, the presence of active depressive symptoms that, in the opinion of the investigator, would affect the subject's ability to complete study assessments, or which would not be in the subject's best interest to participate in the study
  • Presence of orthostatic hypotension at screening: a decrease in systolic blood pressure (at least 20 mm Hg) or diastolic blood pressure (at least 10 mm Hg) within 3 minutes of the subject standing up, compared to pressures obtained while sitting
  • If female, is pregnant or lactating
  • If a sexually active female, is not surgically sterile or at least 2 years post-menopausal, or does not agree to utilize a highly effective hormonal method of contraception (an IUD, or vasectomized male partner is also acceptable), in combination with a barrier method, from screening through at least 4 weeks after the completion of study treatment. If a sexually active male, does not agree to utilize condoms from screening through at least 4 weeks after the completion of study treatment.
  • Treatment with an investigational drug or device within 30 days prior to screening
  • Treatment with an investigational biologic within 6 months or 5 half-lives, whichever is longer, prior to screening
