This trial is to investigate the safety and potential therapeutic efficacy of allogeneic administration of umbilical cord-derived MSCs (UC-MSCs) in combination with standard neurological complications after ischemic stroke treatment in Vietnam.


Stroke is the second leading cause of death behind ischemic heart disease worldwide. Traditional treatments have some limitations whereas preclinical data suggest that stem cell therapy is a promising regenerative medical treatment given the limited capacity of the central nervous system for self-repairs after ischemic stroke. Previous studies have shown that umbilical cord blood-derived Mesenchymal stem cell (UC-MSC) infusion improves the outcomes of several neurological damage conditions, including stroke. These results encouraged us to initiate the phase I/II clinical trial aiming to evaluate the safety and the efficiency of UC-MSC transplantation in the treatment of patients with neurological complications after ischemic stroke. This case-control phase I/II trial is conducted at Vinmec Times City International Hospital, Hanoi, Vietnam between 2021 and 2023. In this trial, 48 patients with neurological complications after ischemic stroke will be enrolled into 3 groups: UC-MSC infusion via intravenous route group (16), UC-MSC infusion via intrathecal administration route group (16), and control group (16). The UC-MSC group (IV/intrathecal) will receive two doses of thawed UC-MSC product at 1.5x106 cells/kg patient body weight with an intervention interval of three months. The primary outcome measures will include the incidence of prespecified administration-associated adverse events (AEs) and serious adverse events (SAEs). The potential efficacy will be measured using these scales including National Institutes of Health Stroke Scale-NIHSS, Functional Independence Measure -FIM, Modified Ashworth Scale-MAS, Fine motor skills-FMS, 36-Item Short Form Survey -SF-36. The clinical evaluation will be conducted at baseline and 3-, 6- and 12-months post-intervention.
