Study of Purified Umbilical Cord Blood CD34+ Stem Cell on Chronic Ischemic Stroke

July 31, 2012 updated by: Shinn-Zong Lin, China Medical University Hospital

An Exploratory Clinical Trial to Assess Treatment of Chronic Ischemic Stroke With Brain Transplants of Purified CD34+ Umbilical Cord Blood Stem Cells

The purpose of the study is to determine the safety and possible effectiveness of brain transplants of CD34+ stem cells obtained from umbilical cord blood (UCB) to treat stroke.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

The study will use CD34+ cells (a special kind of cell that is believed to be a stem cell) isolated from UCB (blood obtained at birth from the umbilical cord blood of babies). StemCyte, a leading accredited UCB banking company with branches in the United States and Taiwan, will provide the units of UCB that match at least 5 out of 6 HLA (human leukocyte antigens) for transplantation. The HLA-matching is the same as that used to match cells and organs for transplantation so that the body does not reject the cells. We will isolate CD34 cells from these units, purified them, suspend the cells in solution (1 ml containing 2-8 million cells), and inject the cells into brain around the site damaged by the stroke

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

35 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Subjects can be of either gender and must be between 35 through 75 years of age.
  2. Subjects must have had ischemic stroke more than 6 and less than 60 months ago.
  3. Subjects must have stable hemiplegia or hemiparesis condition at least for 3 months.
  4. Subjects must have stroke-induced clinical deficits affecting motor, perceptual, or language functions, with a National Institutes of Health Stroke Scale (NIHSS) of 5-15.
  5. Subjects must have stroke in the middle cerebral artery territory.
  6. Subjects must have an available umbilical cord blood unit that has an HLA-match of at least 5:6 (HLA-A, -B, and -DR).
  7. Subjects must be able to read and understand the informed consent form that has been approved by the appropriate Institutional Review Board (IRB). The subject must sign and date the informed consent form before any study-specific procedures. (Note: If a subject consents to participation but is not in a position to sign and date the informed consent form personally because of his or her physical conditions, the consent form must be confirmed orally at the time of consent, marked or finger printed by the subject voluntarily). The informed consent procedure must be observed by an independent witness who is present throughout the whole informed consent process and sign the consent form.

Exclusion Criteria:

  1. Subject has evidence of a non-ischemic mechanism, subarachnoid hemorrhage, primary intracerebral or intraventricular hemorrhage or MRI has shown that the occlusion is not in the middle cerebral artery territory.
  2. Pregnant or lactating women.
  3. History of alcohol or drug abuse in the previous 3 months.

  4. Subjects must not have the following conditions in documents:

    • significant renal, cardiovascular, hepatic, or psychiatric disease
    • abnormal blood coagulation parameters,
    • immunodeficiency (e.g. AIDS)
    • tumors, leukemia, and other cancer that may interfere with the clinical trial protocol
    • infectious diseases, including hepatitis, or other conditions that may be a contraindication to the planned therapies and evaluation.
  5. Subject must not be currently participating in another investigational study or taking any investigational drug within the last four weeks before the screening of this study.
  6. Any other condition that, in the opinion of the investigator, suggests that the subject would not be compliant with the study protocol and would not be suitable to perform a surgery or to participate in the study.
