Study Summary

This is a placebo controlled, randomized, double blinded study including Phase 1 and Phase 2. Phase I study is a safety assessment and Phase 2 study is incline to assess effectiveness of MSCs. Potential subjects must be screened and consented before enrolled.

The primary objective of this study is to determine the effects of early intravenous infusion of allogeneic human umbilical cord mesenchymal stem cells (HucMSCs or MSCs used in the following section) for patients with acute ischemic stroke. Eligible patients will receive a single dose of MSCs or placebo within 24 hours after stroke. Patients will be followed for 2 years post infusion for safety and efficacy (change in neurological symptoms and quality of life). Assessments will occur during transplantation and at 3,7, 14 days and1,3, 6, 12, 18 and 24 months after infusions of stem cells.

Study Description

In Phase 1 study, the eligible patients of acute cerebral infarction within 7 days after onset will be randomized to MSCs group or control group and receive intravenous MSCs 2 x 10^6/kg or placebo as a single dose, respectively. Each group will enroll 10 patients and patients will be followed for 2 years to observe the adverse events and evaluate the safety of MSCs for acute ischemic stroke patients.

The safety and preliminary effectiveness of MSCs in the treatment of acute cerebral infarction will be summarized after all patients of Phase 1 study were followed for 3 months post infusion, and the report will be submit to the academic committee and the ethics committee to evaluate before approval to begin the Phase 2 study.

In Phase 2 study, 100 patients with acute infarction within 24 hours after onset will be enrolled and randomized to MSCs group or control group. Patients will have baseline laboratory examinations and cerebral image (MRI or CTP). Enrolled patients will receive intravenous infusion of 2*10^6/kg MSCs or placebo for a single dose and follow for 24 months to assess the adverse events, neurological functional recovery and quality of life.
