Ischemic Stroke
Conditions
Brief summary
The goal of this clinical trial is to evaluate the efficacy, safety, and pharmacodynamic characteristics of Human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) in adults with ischemic stroke in the anterior circulation during the recovery phase. Researchers will compare hUC-MSCs to a placebo to determine whether hUC-MSCs treatment is effective in treating recovery-phase anterior circulation ischemic stroke.
Detailed description
This study aims to further evaluate the efficacy and safety of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) in the treatment of stroke. Eligible participants will be randomized to receive either intravenous infusions of hUC-MSCs or a matching placebo. Over the 12-month study period, participants will be required to attend regular clinic visits for comprehensive neurological assessments, including the Fugl-Meyer Assessment (FMA), Modified Rankin Scale (mRS), National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI), and Mini-Mental State Examination (MMSE), as well as vascular imaging studies and biomarker analyses. Additionally, participants (or their caregivers, where applicable) will be instructed to consistently document neurological symptoms, functional activities, and the use of any rehabilitation medications or assistive devices.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fugl-Meyer Assessment motor score | 12 months | The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based scale used to evaluate motor impairment. Its motor score, which ranges from 0 to 100, serves as a key parameter for quantifying motor recovery, where a higher score indicates better motor function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Modified Rankin Scale | 12 months | The Modified Rankin Scale (mRS) is designed to evaluate the degree of dependence in daily activities rather than specific impairments. The mRS is a simple ordinal scale ranging from 0 to 6, where 0 indicates no symptoms and 6 indicates death. A lower score on the scale signifies a better level of independence and a lower degree of disability. |
| National Institutes of Health Stroke Scale | 12 months | The National Institutes of Health Stroke Scale (NIHSS) is designed to evaluate the effects of a stroke on key functional domains such as consciousness, vision, motor strength, sensation, and language.The NIHSS score ranges from 0 to 42, with a higher score indicating more severe neurological deficits. |
| Barthel Index | 12 months | The Barthel Index (BI) is commonly employed to evaluate functional disability and monitor rehabilitation progress in patients with chronic conditions or following events such as stroke. The total score ranges from 0 to 100, with a higher score indicating a greater degree of functional independence. |
| Mini-Mental State Examination | 12 months | The Mini-Mental State Examination (MMSE) is a standardized screening tool designed to provide a quick assessment of an individual's global cognitive function.The total score ranges from 0 to 30, with a higher score indicating better cognitive performance. |
