About this study

Official title: Randomized Open Multicenter Clinical Study to Evaluate the Safety and Effectiveness of Guided Cartilage Regeneration Membrane for Repair of Articular Cartilage Injury

Guided cartilage regeneration membrane for repairing the safety and effectiveness of articular cartilage injury

Read the detailed description

MRI evaluation using guided cartilage regeneration membrane for articular cartilage injury repair 730 days (2 years) is the main indicator of this trial. In this experiment, we observe the improvement of Lysholm score, VAS score, ratio change of regenerated cartilage T2 value to normal cartilage T2 value, and ratio of regenerated cartilage △R1 value to normal cartilage △R1 value Indicators such as value changes are secondary evaluation indicators.

Being tested
Guided cartilage regeneration membrane, Microfracture

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Guided cartilage regeneration membraneCombination product

    On the basis of microfracture, the blood clot released from the defect area is covered with a guide cartilage regeneration membrane to provide an attached scaffold for the cells in the blood clot.

  • MicrofractureProcedure or surgery

    Operate in accordance with the clinical microfracture surgery method.

Study groups in NCT04463238
Study groupRoleWhat they receive
Cartilage membrane surgeryExperimentalThe test group applied the guidance provided by Shaanxi Baiao Regenerative Medicine Co., Ltd. Cartilage regeneration membrane combined with microfracture surgery.
Receives: Combination Product: Guided cartilage regeneration membrane; Procedure: Microfracture
MicrofractureOtherThe control group was treated with microfractures widely recognized at home and abroad.
Receives: Procedure: Microfracture

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. MRI evaluation of articular cartilage injury 730 days (2 years) after repair

    The nuclear magnetic evaluation indicators are as follows:

    1. Cartilage defect repair filling degree;
    2. Fusion of repair tissue and adjacent normal cartilage;
    3. Repair tissue surface structure;
    4. Repair the internal structure of the organization.

    The MRI score of the experimental group before and after treatment increased by an average of 5 points compared with the control group.

    Measured: End of surgery to 730 days after surgery

Secondary outcomes (2)
  1. Change in ratio of regenerated cartilage T2 value to normal cartilage T2 value

    The closer the ratio of the regenerated cartilage T2 value to the normal control cartilage T2 value is 1, it means that the regenerated cartilage The closer the water content and collagen arrangement are to normal cartilage.

    Measured: At 24 months after surgery

  2. Change in ratio of regenerated cartilage △R1 value to normal cartilage △R1 value

    The closer the ratio of the regenerated cartilage △R1 value to the normal control cartilage △R1 value is 1, it means that the GAG content of regenerated cartilage is closer to normal cartilage.

    Measured: At 24 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Guided cartilage regeneration membrane and Microfracture in people with Articular Cartilage Injury and Knee Ligament Injury, run by Peking University Third Hospital at 8 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yingfang Ao, PhD (13401096777 ext. 13401096777, gcrm_bys01@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MRI evaluation of articular cartilage injury 730 days (2 years) after repair (time frame: End of surgery to 730 days after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2020.
