Overview
Primary Objective:
To determine the efficacy of SAR442168 compared to placebo in delaying disability progression in NRSPMS
Secondary Objective:
To evaluate efficacy of SAR442168 compared to placebo on clinical endpoints, magnetic resonsnce imaging (MRI) lesions, cognitive performance, physical function, and quality of life To evaluate safety and tolerability of SAR442168 To evaluate population pharmacokinetics (PK) of SAR442168 in NRSPMS 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 24 to 48 months.
