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.
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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Time frame: 24 months post transplantation
the National Institutes of Health Stroke Scale (NIHSS) of 3 months
The NIHSS neurologic examination includes 15 individual elements that measure motor and sensory function, language and speech production, vision, level of consciousness and attention, and neglect. The scores of each element are summed (range from 0 to 42) to evaluate the severity of neurological deficits. The more higher score means the more severe neurological dysfunction.
Time frame: 3 months post transplantation
the Barthel index (BI) of 3 months
The BI (range from 0 to 100) are used to assess the difference of activities of daily living between two groups. the score ≤40 means severe dependence， score 41\~60 means moderate dependence, score 61\~99 means mild dependence and score 100 means independence.
