NCT ID NCT07243561

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage trial is testing whether a nasal spray made from stem cell exosomes can safely improve core symptoms in 40 children aged 3-7 with autism. Half the children get the spray every other day for 10 doses, while the other half receive no treatment. Researchers will track side effects and changes in autism severity over 24 weeks.

What this could mean

Active substance

human umbilical cord mesenchymal stem cell-derived exosomes (hUC-MSC-EXOs) nasal spray

What this could lead to

If it works, this could point toward a new way to ease core autism symptoms in children using a simple nasal spray.

What could go wrong

This is an early Phase 1/2 trial with only 40 children, so results may not apply broadly. The treatment is experimental and safety is still being checked.
