Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Active patients (30 to 75 years)
  • A localized osteochondral defect of both condyle and/or tibia grade 4 (ICRS classification)
  • with cartilage on the tibial surface no more than grade 3-4, of size < 3-4 cm2, with 3/4 of meniscus present.
  • Stable knee ; previous ligament reconstruction, if stable
  • A defect that is 1 - 4 cm2 or more, up to 6 cm2, located on the femoral condyle and /or less of 4 cm2 for tibial plate, and IKS score <75.
  • Kissing lesions admitted
  • Ability to understand and willingness to sign consent form

Who cannot join

  • Patients younger than 30 years and older than 75 years
  • Diffuse and advanced articular cartilage degeneration of the joint
  • Axial malalignment, meniscal pathology, and ligamentous instability are relative contraindications that have to be dealt with primarily either concomitantly or before the transplantation during 1 of the 2 stages of the procedure. Refusal of the patient to address these conditions in presence of a cartilage lesion is a criterion for exclusion from the study, to avoid the impact of these knee pathologies on the final results
  • Existing infection in or around the joint \& lesions of infectious or oncologic etiology.
  • Debilitated patients.
  • Immunocompromised patients.
Show all 9Show fewer
  • Patients with autoimmune disorders \& systemic inflammatory disease.
  • Preoperative poor neurological or vascular status of the affected limb.
  • Specific contraindications include the use of tobacco and medications that may impair cell proliferation, such as NSAIDs and immunosuppressive drugs. Patients must be nicotine-free (stop smoking) prior to the procedure, as studies have shown that the oxidative effect of smoking impairs cell function and subsequent healing.

About this study

Official title: Pilot Study of A One-Step Procedure for the Use of Autologous Bone Marrow Mesenchymal Stem Cells Stimulated by Proteins Scaffold to Heal Under Arthroscopy Full-Thickness Defects Articular Cartilage and Osteoarthrosis of the Knee.

The purpose of this pilot study is to investigate the efficacy and safety of autologous transplantation, under arthroscopy, of Bone Marrow Mesenchymal stem cells, using, with a cell separator, a fresh non-culture expanded Autologous Bone Marrow derived Mesenchymal Stem, mixed and activated with proteins scaffold in patient with Knee cartilage defects and osteoarthritis. Based on extensive preclinical investigations, the technology of using freshly isolated bone marrow mononuclear cells mixed with proteins seems safe and most effective for a one-step correction of cartilage defect and restoration of the osteochondral complex, because the same mixture can generate cartilage in the vasculature-free knee joint, and bone in the environment of bone defects.

Read the detailed description

Before the implantation of the mesenchymal stem cells, a knee arthroscopy procedure is made for the debridement of the meniscal and cartilage lesions, with microperforation and abrasion, preparation of the osteochondral defect to receive the transplantation, patellar lateral release if necessary.

Then, the investigators use a fresh non-culture expanded autologous bone marrow derived mesenchymal mononuclear stem cells, stimulated with a protein matrix and mixed in a collagen hydroxyapatite scaffold. This cellular paste is transplanted in the prepared defect, under arthroscopy, with injection of platelet rich plasma.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Transplantation of Bone Marrow Stem Cells Activated in Knee Arthrosis in people with Osteoarthritis and Knee Osteoarthritis, run by Michel Assor, MD at 1 site in France.

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 7 inclusion and 9 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 8 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Michel Assor, MD (0033611950518 / 0033609505060, michel.assor@free.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

IKS, International Knee Score (time frame: 6 months). The study lists 2 primary outcomes in all. 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 8 Jan 2013.
