Study Purpose:
This is a parallel treatment, Phase 2, randomized, double-blind study to assess the efficacy, safety, tolerability, PK, and PD of twice daily (BID) oral SAR443820 compared with placebo in male and female participants,18 to 80 years of age with ALS followed by an open label, longterm extension period.Study ACT16970 consists of 2 parts (A and B) as follows:
Part A is a 24week, double blind, placebo controlled part, preceded by a screening period of up to 4 weeks before Day 1.
On Day 1 of Part A, participants will be randomized in a 2:1 ratio to the SAR443820 treatment arm or matching placebo arm as listed below:
Treatment arm: SAR443820, BID
Placebo arm: Placebo, BID
Randomization will be stratified by the geographic region of the study site, region of ALS onset (bulbar vs other areas), use of riluzole (yes vs no), use of edaravone (yes vs no) and use of the combination of sodium phenylbutyrate and taurursodiol (named Relyvrio in the United States of America [USA] and Albrioza in Canada) (yes vs no). Participants will attend in clinic study assessments at baseline (Day 1), Week 2, Week 4, Week 8, Week 16, and Week 24, and will receive a phone call at Week 12 and Week 20. All ongoing participants in Part A will rollover to part B. The Week 24 Visit is the end of Part A and the beginning of Part B.
Part B is an open label, longterm extension period that starts from the end of Part A (Week 24) and continues up to Week 106. The objectives of Part B are to further determine the safety and efficacy of longterm SAR443820 treatment. The treatment assignment of participants in Part A will remain blinded to Investigators, participants, and site personnel until the end of Part B. Every participant, except those who discontinued Investigational Medicinal Product (IMP) treatment permanently in Part A , will receive BID oral tablets of SAR443820 in Part B.

Inclusion Criteria:- Diagnosis of possible, clinically probable ALS, clinically probable laboratory supported ALS, or clinically definite ALS according to the revised version of the El Escorial World Federation of Neurology criteria
- Time since onset of first symptom of ALS ≤2 years.
- Slow Vital Capacity (SVC) ≥60% of the predicted value.
- Be able to swallow the study tablets at the screening visit.
- Either not currently receiving riluzole or on a stable dose of riluzole for at least 4 weeks before the screening visit. Participants receiving riluzole are expected to remain on the same dose throughout the duration of the study.
- Either not currently receiving edaravone or on the approved standard schedule of edaravone treatment. Participants receiving edaravone must have completed at least 1 cycle of treatment before the screening visit and are expected to continue edaravone treatment throughout the duration of the study.
- Either not currently receiving the combination of sodium phenylbutyrate and taurursodiol or on the approved standard schedule of the combination of sodium phenylbutyrate and taurursodiol treatment for at least 4 weeks before the screening visit. Participants receiving the combination of sodium phenylbutyrate and taurursodiol are expected to remain on the approved standard schedule throughout the duration of the study.
- Participants with a body weight no less than 45 kg and body mass index no less than 18 kg/m2 at the screening visit
- Female participants with childbearing potential are eligible to participate if they are not pregnant or breastfeeding and agree to use adequate contraceptive method during study intervention period and for at least 32 days after the last dose of study drug.
- Male participants must agree to use highly effective contraceptive method during the study period and for at least 92 days following their last dose of the study drug. Male participants must not donate sperms for the duration of study and 92 days after last dose of study drug.
Exclusion Criteria:
- A history of seizure (History of febrile seizure during childhood is allowed).
- Having central IV lines, such as a peripherally inserted central catheter (PICC XE ' PICC ' \f Abbreviation \t 'peripherally inserted central catheter' ) or midline or portacath lines.
- With significant cognitive impairment, psychiatric disease, other neurodegenerative disorder (eg, Parkinson disease or AD), substance abuse other causes of neuromuscular weakness, or any other condition that would make the participants unsuitable for participating in the study or could interfere with assessment or completing the study in the opinion of the Investigator.
