Study Summary

Primary Objective: To determine the efficacy of SAR441344 as measured by reduction of the number of new active brain lesions Secondary Objective: * To evaluate efficacy of SAR441344 on disease activity as assessed by other MRI measures * To evaluate the safety and tolerability of SAR441344 * To evaluate pharmacokinetics of SAR441344

Primary Outcome

Cranial (brain) MRI was performed to identify number of new GdE T1-hyperintense lesions at Week 12 relative to Week 8 MRI. Central review was used to identify new GdE T1 lesions not present at the previous MRI scans.
