Brief Title ICMJE | Phase 2 Study for SAR443820 in Participants With Amyotrophic Lateral Sclerosis (ALS) | ||||||
Official Title ICMJE | A Phase 2, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of SAR443820 in Adult Participants With Amyotrophic Lateral Sclerosis, Followed by an Open-label Extension | ||||||
Brief Summary | 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, long-term extension period. Study ACT16970 consists of 2 parts (A and B) as follows: Part A is a 24-week, 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:
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 6, Week 8, Week 10, Week 12, Week 16, Week 20, Week 21, Week 22, Week 23, and Week 24. All ongoing participants at Week 24 will rollover to open-label extension Part B. The Week 24 Visit is the end of Part A and the beginning of Part B. Part B is an open-label, long-term extension period that starts from Week 24 and continues up to Week 106. The objectives of Part B are to provide extended access to SAR443820 participants in Part A and to further evaluate the safety and efficacy of long-term SAR443820 treatment. The treatment assignment of participants at randomization in Part A will remain blinded to Investigators, participants, and site personnel until the end of Part B. Every participant, except those who discontinue Investigational Medicinal Product (IMP) treatment permanently in Part A, will receive BID oral tablets of SAR443820 in Part B. |
