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 population pharmacokinetics (PK) of SAR442168 and relevant metabolites and its relationship to efficacy and safety 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. Participants completing the study will be offered to participate in a long term safety study.

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
documented relapse within the previous year OR
documented relapses within the previous 2 years, OR
documented Gd enhancing lesion on an MRI scan within the previous year
Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
Male participants are eligible to participate if they agree to the following during the intervention period and until accelerated elimination procedure
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)
A WOCBP must have a negative highly sensitive pregnancy test at screening and within 24hours 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 multiple sclerosis (PPMS) according to the 2017 revision of the McDonald diagnostic criteria or with nonrelapsing secondary progressive multiple sclerosis (SPMS)

The participant has a history of infection or may be at risk for infection including but not limited to: HIV, transplantation, live attenuated vaccines, progressive multifocal leukoencephalopathy, tuberculosis, hepatitis B or C, any persistent chronic or active recurring infection
Confirmed screening ALT >2 ULN
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
The participant has a history of or currently has concomitant medical or clinical conditions that would adversely affect participation in this study
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

The participant has a lymphocyte count below the lower limit of normal (LLN) at the screening visit
The presence of psychiatric disturbance or substance abuse
Prior/concomitant therapy
The participant is receiving anticoagulant/antiplatelet therapies
The above information is not intended to contain all considerations relevant
