Trial summary

The incidence of atherosclerotic complications is increased after kidney transplantation. Traditional risk factors do not fully explain this increased risk. Atherosclerosis is an inflammatory disease in which all players in the immune response are involved. Read more about this study

About this study

Official title: Influence de l'ORientation de la réponse LYmphocytaire Sur la Survenue de Complications athéromateuses après Transplantation rénale (étude ORLY-EST 2)

The incidence of atherosclerotic complications is increased after kidney transplantation. Traditional risk factors do not fully explain this increased risk. Atherosclerosis is an inflammatory disease in which all players in the immune response are involved. The impact of these immune responses is not well known in immunocompromised patients, particularly among organ transplant. Nevertheless, the work of our group suggest that innate and acquired responses through different mechanisms influencing the evolution of atheromatous disease after transplantation.

The investigators therefore propose to study the impact of the expansion of regulatory T cells on the risk of atherosclerotic complications after transplantation.

Since November 2008, the investigators began a multicenter, prospective study whose purpose is to study in detail the immunological mechanisms of atherosclerosis after transplantation via immunomonitoring cohort of renal transplant patients in the Grand East Interregion. It was planned to include 500 patients and to date a little more than half have been included. After completion of the blood test, the tubes are routed over the Biomonitoring Platform (CIC-BT 506 Besançon) and the samples are stored in CRB Dijon.

The atherosclerotic events are recorded prospectively. The investigators hope to implement as part of ORLY IS, a second study to determine the impact of an expansion of regulatory T cells on the risk of atherosclerotic events.

Our hypothesis is that a cell rate regulatory T below the median results in an increase of 5% of atherosclerotic complications.

Questions about this trial

What is this clinical trial studying?

An observational study of Disorder Related to Renal Transplantation, run by Centre Hospitalier Universitaire de Besancon at 7 sites 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 4 inclusion and 4 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: under way, not looking for participants, as of the sponsor's last update on 3 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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?

This study is still under way. Results are not available in the source record yet.

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?

Percentage of regulatory T cells related to atherosclerotic complications events. (time frame: 5 or 10 years). 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 NCT02843867, which also lists 2 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 3 Aug 2022.
