NCT07232147

Brief Summary

This study, through different administration methods, adopted a randomized, double-blind, placebo-controlled trial design to evaluate the safety and tolerability of human umbilical cord mesenchymal stem cells (hUC-MSCs) in patients with Parkinson's disease, explore their initial effectiveness and the relationship between biological active factors and therapeutic efficacy. The "Clinical Study on the Treatment of Parkinson's Disease with Human Umbilical Cord Mesenchymal Stem Cells" of this study is expected to provide clinical trial evidence for the development of safe and effective clinical cell therapies for patients with Parkinson's disease.

Outcome Measures

Primary Outcomes (5)

  • Incidence of Treatment-Emergent Adverse Events (TEAEs)

    The safety and tolerability of hUC-MSCs will be assessed by monitoring the frequency of all adverse events (AEs) and serious adverse events (SAEs). Measure: Number of participants with AEs and SAEs

    From baseline up to 48 weeks

  • Severity of Adverse Events

    Severity of AEs and SAEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0. Measure: Grade on NCI-CTCAE v5.0 scale

    From baseline up to 48 weeks

  • Safety Assessments: Vital Signs

    Changes in vital signs including body temperature, heart rate, blood pressure, and oxygen saturation. Measure: Number of participants with clinically significant changes in vital signs

    From baseline up to 48 weeks

  • Safety Assessments: Laboratory Parameters

    Changes in laboratory tests including complete blood count, coagulation profile, liver and kidney function, BNP, D-dimer, and serum troponin. Measure: Number of participants with clinically significant abnormal laboratory values

    From baseline up to 48 weeks

  • Safety Assessments: Physical Examination

    Findings from physical examinations, including skin lesions/rashes. Measure: Number of participants with clinically significant physical examination findings

    From baseline up to 48 weeks

Secondary Outcomes (5)

  • Change in Motor Function as Assessed by MDS-UPDRS Part III

    Baseline, 4, 16, 28, and 48 weeks

  • Change in Disease Staging as Assessed by Hoehn & Yahr Staging

    Baseline, 4, 16, 28, and 48 weeks

  • Change in Non-Motor Symptoms as Assessed by NMSS

    Baseline, 4, 16, 28, and 48 weeks

  • Change in Depressive Symptoms as Assessed by HAMD

    Baseline, 4, 16, 28, and 48 weeks

  • Change in Anxiety Symptoms as Assessed by HAMA

    Baseline, 4, 16, 28, and 48 weeks

Study Arms (1)

Human-derived stromal cells

EXPERIMENTAL

Administer human matrix cells by intravenous infusion or nasal drip once every two weeks, for a total of 5 administrations.

Biological: Human-derived stromal cells

Interventions

The human-derived stromal cells were administered intravenously once every two weeks, for a total of 5 times. Among them, half of the subjects (10 people) received intranasal administration of human-derived stromal cells once a day, in the morning and evening, from the 6th to the 8th day after each administration; the remaining subjects (10 people) received nasal administration of placebo once a day, in the morning and evening, from the 6th to the 8th day after each administration.
