About this trial
This is a single-center, randomized, open-label, placebo-controlled, dose-escalation trial. The objective of this research is to evaluate the safety, tolerability, and efficacy of intrathecal administration of human-induced neural stem cell-derived extracellular vesicles (NouvSoma001) for the treatment of neuromyelitis optica spectrum disorders.
