Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mean Overall Response Score (ORS) [ 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. Disability Improvement Response Rate [ Time Frame: Week 52 ]
    Disability improvement response rate is assessed based on the Expanded Disability Status Scale Plus (EDSS+). EDSS+ is comprised of EDSS, Timed 25-Foot Walk (T25FW) and 9-Hole Peg Tests (9HPT).

  2. Overall Response Score (ORS) [ Time Frame: Up to 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).
