Researchers are studying spinocerebellar ataxia types 1 and 3 SCA1 and SCA3 and Huntingtons disease HD, which are serious genetic neurodegenerative disorders without current treatments to slow their progression. This first-in-human trial evaluates a new drug called VO659, designed to target harmful gene mutations by binding to specific RNA sequences. The study aims to assess the safety, tolerability, and how the drug moves through and affects the body when given via spinal injections.
CONDITIONS
