About this study

Official title: Autologous Chondrocyte Transplantation For Articular Cartilage Regeneration. Pilot Study

The purpose of this study is to assess safety and efficacy of autologous chondrocyte implantation delivered arthroscopically into chondral lesions of the knee using clinical, biochemical, and MRI outcomes.

Read the detailed description

Injuries to the articular cartilage of the knee are common. They produce pain and deteriotation of patients' quality of life. The management of focal chondral lesions continues to be problematic for the treating orthopaedic surgeon. Although many treatment options are currently available, none fulfill the criteria for an ideal repair solution: a hyaline repair tissue that completely fills the defect and integrates well with the surrounding normal cartilage. Autologous chondrocyte implantation is a relatively new cell-based treatment method for full-thickness cartilage injuries that in recent years has increased in popularity, with different studies showing promising results. Typically, this implantation is performed in an open-surgery fashion. In our study the implantation of in-house autologous chondrocyte culture is done arthroscopically, situation that may offer advantages in surgery associated morbidity and patient recovery.

What participants receive

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

  • Arthroscopic matrix encapsulated chondrocyte implantationDevice

    Each implant of collagen scaffold contains approximately 6,000,000 autologous chondrocytes. This constructs of 10 mm diameter are implanted arthroscopically at the defect.

What is being measured

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

  1. Change from baseline to different periods in T2 Mapping for cartilage lesions after treatment.

    Special magnetic resonance imaging technique for measurement of collagen and water content, it is expressed in milliseconds.

    Measured: 3, 6, 9, 12, 18, 24 36 months

Secondary outcomes (1)
  1. Change of baseline to different periods in Clinical evaluation

    Clinical assessment with validated knee scores, and adverse effects register are taken.

    Measured: 0, 10, 30 days, 3, 6, 9, 12, 24, 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Arthroscopic matrix encapsulated chondrocyte implantation in people with Tear; Knee, Cartilage, Articular, run by Instituto Nacional de Rehabilitacion at 1 site in Mexico.

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 1 inclusion and 7 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: finished, as of the sponsor's last update on 12 Apr 2017. 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 Mexico. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline to different periods in T2 Mapping for cartilage lesions after treatment. (time frame: 3, 6, 9, 12, 18, 24 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01503970, which also lists 3 linked publications.

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 12 Apr 2017.
