Brief Summary
Stride Dystonia is a randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, and tolerability of VIM0423 in individuals with isolated dystonia. The main objectives of this clinical trial are to determine the following:
- Does VIM0423 therapy improve dystonia symptoms compared to placebo?
- Is VIM0423 well tolerated in individuals with isolated dystonia? and
- Do the therapeutic effects of VIM0423 confer improvements on daily function and quality of life?
