Brief Summary:
This is a open-label, single-arm, dose escalation phase I clinical trial. The goal of this clinical trial is to evaluate the safety and preliminary efficacy of Intrathecal injection human umbilical cord-derived mesenchymal stromal cell-derived extracellular vesicle (hUC-MSC-sEV) in syringomyelia.
Detailed Description:
This is a open-label, single-arm, dose escalation phase I clinical trial. The study will consist of one part: Part 1 will be a dose-escalation study.
A traditional 3+3 dose-escalation design will be implemented in Part 1. Cohort 1 will receive low-dose1×1011particles; Cohort 2 will receive middle-dose2×1011particles; and Cohort 3 will receive high-dose3×1011particles. (Cohort 1 to Cohort 3 will receive a dose of 2 ml per lumbar puncture, administered once a month, for a total of three months.) If no dose-limiting toxicities (DLTs) are observed for 2 weeks after the administration of the first Intrathecal injection, a new cohort will be enrolled at the next planned dose level. If DLTs are observed in one participant in the cohort, an additional three participants will be treated at the same dose level. Dose escalation will be stopped if DLTs are observed in more than 33% of the participants.
