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.

Symptom onset occurred within 7 days prior to enrollment, with associated severe pain, lower limb motor dysfunction, or urinary/bowel impairment.

Males or Females aged between 18 and 65 years.

The Expanded Disability Status Scale (EDSS) score prior to the current disease episode is ≤ 4.

Disqualifiers

Any contraindications to lumbar puncture.

Pregnant or breastfeeding women, and patients with plans to conceive during the trial.

Patients with a known history of allergies to human-derived biological products or those with an allergic predisposition.

Patients who have undergone hematopoietic stem cell transplantation or lymphatic irradiation before enrollment.
