Primary Outcome Measures :
  1. Overall Response Score (ORS) at Week 52 [ Time Frame: Week 52 ]
    The ORS is a composite score derived from 4 components: Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), 9-Hole Peg Test in the dominant hand (9HPT-D), and 9HPT in the non-dominant hand (9HPT-ND).


Secondary Outcome Measures :
  1. 12-week confirmed disability improvement response rate on the Expanded Disability Status Scale Plus (EDSS+) [ Time Frame: 52 weeks ]
    12-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 12 weeks during the treatment period 52-weeks. The EDSS+ is used to assess severity of symptoms of MS and includes the Timed 25 Foot Walk (T25FW), 9-Hole Peg test in either hand (9HPT), and EDSS.

  2. 12-week confirmed disability improvement response rate on Timed 25 Foot Walk (T25FW) [ Time Frame: 52 weeks ]
    12-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 12 weeks during the treatment period 52-weeks. The T25FW is a tool that evaluates mobility and leg function performance.

  3. 12-week confirmed disability improvement response rate on 9-Hole Peg Test in either hand (9HPT) [ Time Frame: 52 weeks ]
    12-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 12 weeks during the treatment period 52-weeks. The 9HPT is a tool that evaluates upper extremity function.

  4. 12-week confirmed disability improvement response rate on Expanded Disability Status Scale (EDSS) [ Time Frame: 52 weeks ]
    12-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 12 weeks during the treatment period 52-weeks. The EDSS is a tool for quantifying disability in multiple sclerosis and monitoring changes in the level of disability.

  5. 24-week confirmed disability improvement response rate on the Expanded Disability Status Scale Plus (EDSS+) [ Time Frame: 52 weeks ]
    24-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 24 weeks during the treatment period 52-weeks. The EDSS+ is used to assess severity of symptoms of MS and includes the Timed 25 Foot Walk (T25FW), 9-Hole Peg test in either hand (9HPT), and EDSS.

  6. 24-week confirmed disability improvement response rate on Timed 25 Foot Walk (T25FW) [ Time Frame: 52 weeks ]
    24-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 24 weeks during the treatment period 52-weeks. The T25FW is a tool that evaluates mobility and leg function performance.

  7. 24-week confirmed disability improvement response rate on 9-Hole Peg Test in either hand (9HPT) [ Time Frame: 52 weeks ]
    24-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 24 weeks during the treatment period 52-weeks. The 9HPT is a tool that evaluates upper extremity function.

  8. 24-week confirmed disability improvement response rate on Expanded Disability Status Scale (EDSS) [ Time Frame: 52 weeks ]
    24-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 24 weeks during the treatment period 52-weeks. The EDSS is a tool for quantifying disability in multiple sclerosis and monitoring changes in the level of disability.

  9. Overall Response Score (ORS) at Week 12 [ Time Frame: Week 12 ]
    The ORS is a composite score derived from 4 components: Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), 9-Hole Peg Test in the dominant hand (9HPT-D), and 9HPT in the non-dominant hand (9HPT-ND).

  10. Overall Response Score (ORS) at Week 24 [ Time Frame: Week 24 ]
    The ORS is a composite score derived from 4 components: Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), 9-Hole Peg Test in the dominant hand (9HPT-D), and 9HPT in the non-dominant hand (9HPT-ND).

  11. Overall Response Score (ORS) at Week 36 [ Time Frame: Week 36 ]
    The ORS is a composite score derived from 4 components: Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), 9-Hole Peg Test in the dominant hand (9HPT-D), and 9HPT in the non-dominant hand (9HPT-ND).

  12. Time to first improvement on 12-week confirmed Expanded Disability Status Scale Plus (EDSS+) [ Time Frame: 52 weeks ]
    12-week confirmed disability improvement is defined as a patient who showed an improvement in the EDSS+ and maintained the improvement for at least 12 weeks during the treatment period 52-weeks. The EDSThe EDSS+ is used to assess severity of symptoms of MS and includes the Timed 25 Foot Walk (T25FW), 9-Hole Peg test in either hand (9HPT), and EDSS.
