STRIDES - a Clinical Research Study of an Investigational New Drug to Treat Spinocerebellar Ataxia

This is a randomized, double-blind, placebo-controlled trial to assess the safety and efficacy of SLS-005 for the treatment of adults with SCA. The study consists of a 2-week screening period, a 52-week treatment period, and a 2-week safety follow-up period. Eligible participants between the ages of 18-75 years, will be randomized to treatment with SLS-005 or equivalent placebo (sodium chloride injection, 0.9%, USP). The study plans to enroll up to 245 participants with SCA3. Biomarkers associated with neuro-axonal injury, pharmacokinetics, Modified Scale for Assessment and Rating of Ataxia (m-SARA), Clinical Global Impression of Severity (CGI-S), Patient Global Impression of Severity (PGI-S), and Friedreich's Ataxia Rating Scale - Activities of Daily Living (FARS-ADL), will be assessed at screening and/or baseline and at scheduled times throughout the study.
