Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized, double-blind, paralleled study. 40 patients will be separated into two groups, and receive basic treatment (Aspirin Tablet). Patients in experimental group will receive hUC-MSC once a month, total 3 times. After the treatment, investigator will have follow-up visit for 6 months, evaluate the security and efficacy of hUC-MSC.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment related-adverse events counting
Time Frame: 26 weeks
patients will be monitored for any adverse events resulting from the treatment of Human Umbilical Cord Mesenchymal Stem Cells
26 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Modified Rankin Scale
Time Frame: 26 weeks

After the first time transplantation, follow-up visit for 26 weeks. Based on Modified Rankin Scale, counting the percentage of different symptom changes to evaluate MSC efficacy:

  • the percentage of participants run from 0-1, no symptom or no significant disability.
  • the percentage of participants run from 0-2, no symptom or slight disability.
  • the percentage of participants decline 2 scales compare to baseline.
  • the percentage of participants decline 1 scale compares to baseline.
26 weeks
Barthel activities of daily living (ADL) Index
Time Frame: 26 weeks

Based on Activity of Daily Living Scale (ADL) to counting the percentage of patients in following condition:

  • the percentage of patients with score > 75
  • the decline of Barthel ADL Index range compares to baseline. Evaluate the efficacy of MSCs treatment
26 weeks
NIH stroke scale (NIHSS)
Time Frame: 26 weeks

According to NIHSS changes after the treatment, evaluate MSCs efficacy by counting the percentage of patients in following condition:

  • the percentage of patients with score 0-1;
  • the percentage of patients with score declined 7 compare to baseline;
  • the percentage of patients with score declined 50% compare to baseline;
  • the declined ranges compare to baseline
