Measured by the Expanded Disability Status Scale (EDSS) CDI-EDSS is defined as a decrease of one point in the EDSS score from baseline to month 24, with an absence of relapse at the point of assessment.

Defined as an episode of CDP without relapse during the 90 days before EDSS increase and during the 6-month period between the EDSS increase and the confirmation of disability progression.

MSFC consists of the timed 25-foot walk test, 9-hole peg test and standard digit modalities test (SDMT)

Presence and number of contrast-enhancing lesions at baseline and the development of new or enlarging lesions between baseline and follow-up will be assessed.
