Summary

Primary Objective:

To assess efficacy of daily SAR442168 compared to a daily dose of 14 mg teriflunomide (Aubagio) measured by annualized adjudicated relapse rate (ARR) in participants with relapsing forms of MS

Secondary Objective:

To assess efficacy of SAR442168 compared to teriflunomide (Aubagio) on disability progression, MRI lesions, cognitive performance and quality of life To evaluate the safety and tolerability of daily SAR442168 To evaluate pharmacodynamics (PD) of SAR442168

Description

Study duration will vary per participant in this event driven trial with a treatment duration of approximately 18 to 36 months.

	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) and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during the study and for the same period of time
	A WOCBP must have a negative highly sensitive pregnancy test urine or serum, as required by local regulations) within the screening period before the first dose of study intervention
	If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive
	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
Exclusion Criteria
	The participant has been diagnosed with primary progressive multiplesclerosis (PPMS) according to the 2017 revision of the McDonald diagnostic criteria or with nonrelapsing secondary progressive multiplesclerosis (SPMS)
	The participant has conditions or situations that would adversely affect participation in this study, including but not limited to
	A short life expectancy due to pre-existing health condition(s) as determined by their treating neurologist
