Clinical Trial Summary

The purposes of the study is to determine the safety and efficacy of treating acute ischemic stroke patients with human umbilical cord mesenchymal stem cells (hUC-MSC).

Description:

This is a randomized, double-blind, paralleled study. 40 patients will be separated into two groups, and receive basic treatment (Aspirin Tablet). Patients in experimental group will receive hUC-MSC once a month, total 3 times. After the treatment, investigator will have follow-up visit for 6 months, evaluate the security and efficacy of hUC-MSC.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Treatment related-adverse events counting	patients will be monitored for any adverse events resulting from the treatment of Human Umbilical Cord Mesenchymal Stem Cells	26 weeks
Secondary	Modified Rankin Scale	After the first time transplantation, follow-up visit for 26 weeks. Based on Modified Rankin Scale, counting the percentage of different symptom changes to evaluate MSC efficacy: the percentage of participants run from 0-1, no symptom or no significant disability.; the percentage of participants run from 0-2, no symptom or slight disability.; the percentage of participants decline 2 scales compare to baseline.; the percentage of participants decline 1 scale compares to baseline.	26 weeks
Secondary	Barthel activities of daily living (ADL) Index	Based on Activity of Daily Living Scale (ADL) to counting the percentage of patients in following condition: the percentage of patients with score > 75; the decline of Barthel ADL Index range compares to baseline. Evaluate the efficacy of MSCs treatment	26 weeks
Secondary	NIH stroke scale (NIHSS)	According to NIHSS changes after the treatment, evaluate MSCs efficacy by counting the percentage of patients in following condition: the percentage of patients with score 0-1; the percentage of patients with score declined 7 compare to baseline; the percentage of patients with score declined 50% compare to baseline; the declined ranges compare to baseline	26 weeks
