Autologous Endothelial Progenitor Cells Transplantation for Chronic Ischemic Stroke

April 1, 2021 updated by: Zhen-Zhou Chen, Southern Medical University, China
Stroke is a frequently occurring and common diseases in nervous system,and most of the survivors will remain disorders of motor,sensory and cognition function.Stem cell transplantation provides a promising approach for rehabilitation. The main objective of this study is to evaluate the efficacy and safy of the transplantation of autologous endothelial progenitor cells in patients with chronic stroke.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Stroke is a frequently occurring and common diseases in nervous system,and most of the survivors will remain disorders of motor,sensory and cognition function.It will brought heavy burden to patients themselves,their family and society.Drugs,rehabilitation excise and hyperbaric oxygen will improve functions after acute stroke.However,in the chronic ischemic stroke,there was few methods to improve the functions.In recently research,stem cell will be a new methods to improve the neural function after through differentiate to nervous cells and secrete some neurotrophic factors to repair the damage. In this study, the investigators will assess the safety and feasibility of intracerebral transplantation of autologous endothelial progenitor cells in patients with chronic ischemic stroke. The neurological outcome will be determined after transplantation.

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.

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
Time Frame

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.
