  • The participant has an expanded disability status scale (EDSS) score ≤5.5 at the first Screening Visit

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

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

    • Refrain from donating sperm

Plus either:

  • Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR
  • Must agree to use contraception/barrier as detailed below:

Agree to use a male condom and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak when having sexual intercourse with a woman of childbearing potential (WOCBP) who is not currently pregnant

  • A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions apply:

    • Is not a WOCBP OR
    • Is a WOCBP and agrees to use a contraceptive method that is highly effective (with a failure rate of <1% per year), preferably with low user dependency, during the intervention period and until accelerated elimination procedure is completed (or for at least 10 days after the last dose of SAR442168, if the case was unblinded)

  • The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
  • The participant must have given written informed consent prior to undertaking any study related procedure. This includes consent to comply with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. In countries where the legal age of maturity is greater than 18 years, a specific ICF for such legally minor participants must also be signed by the participant's legally authorized representative

    • A short life expectancy due to pre-existing health condition(s) as determined by their treating neurologist
    • Medical condition(s) or concomitant disease(s) making them nonevaluable for the primary efficacy endpoint or that would adversely affect participation in this study, as judged by the Investigator
    • A requirement for concomitant treatment that could bias the primary evaluation

  • At screening, the participant is positive for hepatitis B surface antigen and/or hepatitis B core antibody and/or is positive for hepatitis C antibody

  • The participant has any of the following:

    • A bleeding disorder or known platelet dysfunction at any time prior to the screening visit
