Summary

The purpose of each study is to independently measure the annualized relapse rate (ARR) with administration of frexalimab compared to a daily oral dose of teriflunomide in male and female participants with relapsing forms of multiple sclerosis (aged 18 to 55 years at the time of enrollment). People diagnosed with relapsing forms of multiple sclerosis are eligible for enrollment as long as they meet all the inclusion criteria and none of the exclusion criteria.

Study details include:

  • This event-driven study will have variable duration of approximately 40 months for the first participant being randomized and approximately 20 months for the last participant randomized.
  • The study intervention duration will vary ranging from approximately 12 to 40 months.
  • The assessment of scheduled visits will include 1 common end of study [EOS] visit and 3 follow-up visits) with a visit frequency of every 4 weeks for the first 6 months and then every 3 months.
