Clinical Study of Cord Blood Mononuclear Cells (UCB-MNCs) in the Treatment of Knee Osteoarthritis

November 3, 2022 updated by: Lili Cao
Umbilical cord blood mononuclear cells contain hematopoietic stem cells (HSC), mesenchymal stem cells (MSC), endothelial progenitor cells and other pluripotent stem cells, as well as immature immune cells, which can differentiate into chondrocytes, hematopoietic, epithelial, endothelial and nerve cells. It gives the ability to promote wound healing and vascular microcirculation reconstruction, and has the potential to treat many diseasesHowever, clinical studies on cord blood mononuclear cells in knee osteoarthritis have not been reported in the literature. Therefore, this study aims to explore the safety and effectiveness of cord blood mononuclear cells in the treatment of patients with knee osteoarthritis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

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
Measure Description
Time Frame
Lysholm score
Time Frame: Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
Evaluation of functional perception of daily activities and motor function levels of different intensities.The score ranges from 0 to 100 points, the lower the score, the more severe the knee joint damage.
Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
American knee society knee score
Time Frame: Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
Evaluation of the overall function and shape of the knee joint.The score ranges from 0 to 100 points. The lower the score, the worse the knee joint function.
Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
the knee injury and osteoarthritis score
Time Frame: Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
A questionnaire for evaluating the effectiveness of knee joint injury and osteoarthropathy treatment based on patient self-assessment management.The KOOS score consists of five parts, and each part contains a different number of questions. Each question has a minimum of 0 points and a maximum of 4 points. After the score of each part is calculated separately, it is converted into a percentile score through the conversion formula. A score of 0 in the converted percentile score means that the function of that part of the joint is extremely poor, and a score of 100 means that the function of this part of the joint is completely normal.
Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
Visual Analog Score for pain
Time Frame: Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
Physicians Global Assessment to measure quality of life.The score ranges from 0 to 10 points, the lower the score, the more severe the pain.
Compare the changes of 1 month, 3 months, 6 months and one year before treatment (baseline) and after (third injection)
