Description

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 20 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.

  • The participant must have at least 1 of the following prior to screening:

    • ≥2 documented relapses within the previous 2 years, OR
    • ≥1 documented Gd enhancing lesion on an MRI scan within the previous year.

You CAN'T join if...

  • The participant has been diagnosed with PPMS according to the 2017 revision of the McDonald diagnostic criteria
  • The participant has a history of infection or may be at risk for infection:
  • The presence of psychiatric disturbance or substance abuse.
  • History, clinical evidence, suspicion or significant risk for thromboembolic events, as well as myocardial infarction, stroke, and/or antiphosholipid syndrome and any participants requiring antithrombotic treatment.
  • History or current hypogammaglobulinemia.
  • A history or presence of disease that can mimic MS symptoms, such as, but not limited to neuromyelitis optica spectrum disorder, systemic lupus erythematosus, Sjogren's syndrome, acute disseminated encephalomyelitis, and myasthenia gravis.
  • The participant has had a relapse in the 30 days prior to randomization.
  • The participant has contraindication for MRI, ie, presence of pacemaker, metallic implants in high risk areas (ie, artificial heart valves, aneurysm/vessel clips), presence of metallic material (eg, shrapnel) in high risk areas, known history of allergy to any contrast medium, or history of claustrophobia that would prevent completion of all protocol scheduled MRI scans.
