Study Endpoints

Primary Endpoints

Time in Month to Clinical Definite Multiple Sclerosis (CDMS) From Kaplan-Meier Estimates
Up to Week 96

CDMS was defined by the occurrence of a second exacerbation or relapse over 96 weeks in participants who presented with Clinically Isolated Syndrome (CIS) accompanied by an abnormal Magnetic Resonance Imaging (MRI) scan. Time was calculated from the date of the stabilization of the baseline CIS episode to the qualifying relapse for the CDMS.

Annualized Relapse Rate
2 years post treatment (IMP) administration

The annualized relapse rate was calculated for each treatment group as follows: the number of relapses observed during the study period divided by the time spent in the study (in years).

Secondary Endpoints

Percentage of Participants Who Converted to Clinical Definite Multiple Sclerosis (CDMS)
Up to Week 96
Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)
Up to Week 96
Time to First Documented Relapse
2 years post treatment (IMP) administration
