简要总结
This clinical trial aims to evaluate the safety and preliminary efficacy of intravenous administration of human bone marrow-derived mesenchymal stem cells (hBMMSCs) in patients with autism spectrum disorder (ASD).
详细描述
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized primarily by impaired social communication, restricted interests, and repetitive, stereotyped behaviors. Currently, there are no effective therapeutic drugs, and main interventions consist of educational rehabilitation and behavioral management.The purpose of this study is to evaluate the safety and preliminary efficacy of hBMMSC intravenous treatment in patients with ASD. The clinical trial intends to involve 42 participants. The trial is expected to last approximately 2 years.
