Trial summary

Osteoarthritis is a very common pathology, especially in an aging population, and a source of disability. Based on standard radiography, the diagnosis is performed late based on the loss of the cartilage thickness. In this context, prosthetic replacement of the joint is a frequent outcome.

About this study

Official title: Evaluation of the Diagnostic Value of a Biomarker of Non-surgical Knee Osteoarthritis: Subchondral Bone Perfusion (GENU-PERF)

Osteoarthritis is a very common pathology, especially in an aging population, and a source of disability. Based on standard radiography, the diagnosis is performed late based on the loss of the cartilage thickness. In this context, prosthetic replacement of the joint is a frequent outcome. New diagnostic biomarkers and herapeutic targets are therefore logically research priorities identified by the European League Against Rheumatisms, osteoarthritis ad hoc committee. The inflammation related to the development of this pathology is mainly studied at the cellular level and essentially in animals. Since inflammatory and vascular phenomena are closely intertwined, medical imaging of the subchondral bone vascularization appears interesting.

The dynamic contrast-enhanced T1 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technique allows the identification of changes in the osteoarthritic subchondral bone vascularization. In osteoarthritic animals, these changes could be identified before the cartilaginous lesions became visible, and could be correlated with the severity of osteoarthritis.

This study would be the first to correlate subchondral bone perfusion measurements (performed with the DCE sequence) of early cartilaginous lesions of the knee, identified by non-invasive MRI (T2 mapping) in humans. This examination will be performed on a 3 Tesla MRI.

If a correlation is demonstrated in the early stages of osteoarthritis in both humans and animals, then infusion of subchondral bone could become a biomarker of osteoarthritis, and serve as a follow-up evaluation of future treatments.

Osteoarthritis is a very common pathology, especially in an aging population, and a source of disability. Based on standard radiography, the diagnosis is performed late because it is based on the loss of cartilage thickness. In this context, prosthetic replacement of the joint is a frequent outcome. New diagnostic biomarkers and new therapeutic targets are therefore logically research priorities identified up today by the European League Against Rheumatisms, osteoarthritis ad hoc committee .

The strictly mechanical nature of osteoarthritis is currently being questioned. Indeed, the primitive role of inflammation in the development of this pathology is more and more discussed. This inflammation is today studied at the cellular level and essentially in animals. Since inflammatory and vascular phenomena are closely intertwined, medical imaging of the subchondral bone vascularization appears interesting.

The dynamic contrast-enhanced T1 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technique allows the identification of changes in the osteoarthritic subchondral bone vascularization. In osteoarthritic animals, these changes could be identified before the cartilaginous lesions became visible, and could be correlated with the severity of osteoarthritis.

In humans, a preliminary investigator study has recently shown that these changes correlate with the importance of osteoarthritic lesions in patients with advanced osteoarthritis. Up to date, no clinical study has so far been initiated to evaluate the diagnostic value of vascularization markers of subchondral bone in early knee osteoarthritis.

In this context, this prospective monocentric study aims to define the role of DCE medical imaging in the diagnosis of early (non-surgical) patella-femoral osteoarthritis.

This study would be the first to correlate subchondral bone perfusion measurements (performed with the DCE sequence) with early cartilaginous lesions, identified by non-invasive MRI (T2 mapping) in humans. This examination will be performed on a 3 Tesla MRI.

If a correlation is demonstrated in the early stages of osteoarthritis in both humans and animals, then infusion of subchondral bone could become a biomarker of osteoarthritis, and serve as a follow-up evaluation of future treatments.

What is being measured

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

  1. Correlation between T2 cartilage value and endothelial transfer constant (Ktrans)

    T2 (transverse relaxation time) mapping can evaluate the status of the cartilage matrix and identify biochemical changes. T2 is the time constant which determines the rate at which excited protons reach equilibrium or go out of phase with each other. It is a measure of the time taken for spinning protons to lose phase coherence among the nuclei spinning perpendicular to the main field.

    Ktrans is a constant representing the volume transfer between blood plasma and extravascular extracellular space. its units are given in values of (1/time)

    Measured: Thirty minutes after MRI

  2. Correlation between T2 cartilage value and reflux rate (Kep)

    The infusion pharmacokinetics parameters are as follows:

    Ktrans, Kep Kep represents the time constant for gadolinium reflux from the extravascular extracellular space back into the vascular system

    Measured: Thirty minutes after MRI

  3. Correlation between T2 cartilage value and initial slope of the kinetic curve

    The infusion non-pharmacokinetics parameters are as follows:

    • initial slope, time at peak, area under the curve

    Measured: Thirty minutes after MRI

  4. Correlation between T2 cartilage value and area under the kinetic curve

    The infusion non-pharmacokinetics parameters are as follows:

    • initial slope, time at peak, area under the curve

    Measured: Thirty minutes after MRI

  5. Correlation between T2 cartilage value and time at peak

    The infusion non-pharmacokinetics parameters are as follows:

    • initial slope, time at peak, area under the curve

    Measured: Thirty minutes after MRI

Questions about this trial

What is this clinical trial studying?

An observational study of Knee Osteoarthritis, run by Lille Catholic University 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 5 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 1 Dec 2022. 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.

Are results available for this study?

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

Contact Amélie Lansiaux, Md, PhD (03 20 22 52 69 ext. +33, lansiaux.amelie@ghicl.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation between T2 cartilage value and endothelial transfer constant (Ktrans) (time frame: Thirty minutes after MRI). The study lists 5 primary outcomes in all. 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 NCT04324554, which also lists 1 linked publication.

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?
