Official title

A Multicenter, Double-Blind, Randomized, Placebo-Controlled, Phase II Clinical Study to Evaluate the Efficacy and Safety of IxCell hUC-MSC-S in Patients With Ischemic Stroke in the Recovery Phase

Overview

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.

Interventions

  • Drug Placebo
    Intravenous injection of placebo
  • Drug IxCell hUC-MSC-S (Human Umbilical Cord Mesenchymal Stem Cells)
    Intravenous injection of IxCell hUC-MSC-S

Primary outcome measures

  • Fugl-Meyer Assessment motor score [Time frame: 12 months]
Secondary outcome measures (4)
  • Modified Rankin Scale [Time frame: 12 months]
  • National Institutes of Health Stroke Scale [Time frame: 12 months]

Eligibility criteria

Inclusion criteria

  • Age ≥18 years and ≤70 years, regardless of gender.
  • 14 to 90 days after ischemic stroke.
  • Clinical diagnosis of anterior circulation ischemic stroke.

  • It was anticipated that participants would either be able to give informed consent or have a legal representative who could do so.

Exclusion criteria

  • People who had a history of epilepsy, dementia, Parkinson's disease, severe depression, or other neurological or psychiatric disorders.
