    Change in cognitive function at the EOS compared to baseline as assessed by the Symbol Digit Modalities Test (SDMT)

  7. Change in cognitive function as assessed by CVLT-II [ Time Frame: From Baseline up to approximately 60 months ]
    Change in cognitive function at the EOS compared to baseline as assessed by the California Verbal Learning Test II (CVLT-II) where available

  8. Change in Multiple Sclerosis Quality of Life [ Time Frame: From Baseline up to approximately 60 months ]
    Change in Multiple Sclerosis Quality of Life-54 (MSQoL-54) at the EOS compared to baseline

  9. Safety and Tolerability [ Time Frame: From screening up to approximately 60 months ]
    Number of participants with adverse events (AEs), Serious AEs, AEs leading to permanent study intervention discontinuation, and adverse events of special interest (AESI)

  10. Population pharmacokinetics [ Time Frame: Months 6, 9 and 12 ]
    Plasma concentration of SAR442168 (population PK assessment) at Months 6, 9, and 12

  11. Change in plasma neurofilament light chain (NfL) [ Time Frame: From Baseline up to approximately 60 months ]
    Change in NfL levels from at the EOS compared to baseline

  12. Change in lymphocyte phenotype subsets [ Time Frame: From Baseline up to approximately 60 months ]
    Change in lymphocyte phenotype subsets in whole blood at the EOS compared to baseline in a subset of participants

  13. Changes in serum Immunoglobulin level [ Time Frame: From Baseline up to approximately 60 months ]
