Study Endpoints
Primary Endpoints
Brain Magnetic Resonance Imaging (MRI) Assessment: Number of New Gadolinium (Gd) Enhancing T1-hyperintense Lesions
After 12 weeks of SAR442168 treatment for SAR442168 reporting arms (i.e., at Week 12 for Cohort 1 participants, at Week 16 for Cohort 2 participants) and at Week 4 for Cohort 2 placebo

Number of new Gd-enhancing T1-hyperintense lesions was detected by brain MRI at the end of 12 weeks of SAR442168 treatment (i.e., at Week 12 for Cohort 1 participants and Week 16 for Cohort 2 participants). Data was planned to be collected and analyzed on pooled population of participants at each dose level of SAR442168 (either in Cohort 1 and 2) and pooled population of participants receiving placebo in Cohort 2 and was not planned to collected during placebo administration in Cohort 1 (Weeks 12 to 16).

Secondary Endpoints

Cohort 1: SAR442168 5 mg Then PlaceboEXPERIMENTALParticipants received SAR442168 5 milligrams (mg), orally once daily for first 12 weeks then crossed over to matching placebo orally once daily for 4 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 1: SAR442168 15 mg Then PlaceboEXPERIMENTALParticipants received SAR442168 15 mg, orally once daily for first 12 weeks then crossed over to matching placebo orally once daily for 4 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 1: SAR442168 30 mg Then PlaceboEXPERIMENTALParticipants received SAR442168 30 mg, orally once daily for first 12 weeks then crossed over to matching placebo orally once daily for 4 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 1: SAR442168 60 mg Then PlaceboEXPERIMENTALParticipants received SAR442168 60 mg, orally once daily for first 12 weeks then crossed over to matching placebo orally once daily for 4 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 2: Placebo Then SAR442168 5 mgEXPERIMENTALParticipants received placebo matching to SAR442168 tablets, orally once daily for first 4 weeks then crossed over to SAR442168 5 mg orally once daily for 12 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 2: Placebo Then SAR442168 15 mgEXPERIMENTALParticipants received placebo matching to SAR442168 tablets, orally once daily for first 4 weeks then crossed over to SAR442168 15 mg orally once daily for 12 weeks during the 16 weeks treatment period. To maintain the blinding, each participant was given a total of 4 tablets daily, either of SAR442168 or SAR442168 and placebo, to achieve the specified daily dose of SAR442168.
Cohort 2: Placebo Then SAR442168 30 mgEXPERIMENTALParticipants received placebo matching to SAR442168 tablets, orally once daily for first 4 weeks then crossed over to SAR442168 30 mg orally once daily for 12 weeks during the 16 weeks treatment period.
