About this study

Official title: Bio-collection for the Discovery of New Biomarkers for the Prediction of Cardiovascular Events

The main goal of this project is to constitute a collection of biological samples, obtained through the clinical activity of the Centre for Screening and Prevention of Atherosclerosis at Toulouse University Hospital, managing patients in primary or secondary prevention for cardiovascular (CV) diseases. The main objective is to validate new biomarkers with prognostic value regarding the onset of future CV events. Besides, the biological collection will enable patho-physiological studies on atherosclerosis related diseases.

Read the detailed description

Cardiovascular (CV) diseases, particularly those secondary to atherosclerosis, are a leading cause of morbidity and mortality in modern societies. Classical CV risk factors, including age and gender, family history, tobacco smoking, hypertension, diabetes, dyslipidemia and obesity cannot predict more than 50% of future CV events. Use of specific scores (like the SCORE chart) does not much contribute to the precise evaluation of patients classified at moderate risk. Thus, more research is needed: 1) to study patho-physiological mechanisms of the atherothrombotic process in order to identify new pharmacological targets and, 2) to validate new biomarkers with a strong predictive value regarding the onset of hard CV clinical events. Moreover, genetic polymorphisms underlie an individual's susceptibility to develop atherosclerotic diseases. Identification of those gene variants might help to define a personalized approach for the treatment of CV diseases. Patients consulting the Centre for Screening and Prevention of Atherosclerosis (CDPA) are submitted to a personal face-to-face interview addressing their life style, nutritional and smoking habits, and their physical activity practice. Clinical examination includes ECG, stress test, ankle-arm systolic index, ultrasonography of arteries (carotid, aorta, lower limb) and determination of a coronary calcification score. Blood samples are taken up for chemistry measurements including lipoproteins (triglycerides, LDL-C, HDL-C, Lp(a)). For the specific purpose of the biological collection, two supplementary blood tubes will be collected (2 x 7 ml); serum, plasma and genomic DNA will be prepared. Patients will be followed up yearly for those on secondary prevention and every 2nd year on primary prevention. Identical investigation will be carried out at every visit. Recruitment period will spread over 5 years and follow-up will be pursued up to 8 years.

What is being measured

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

  1. measurement of the candidate biomarker

    measurement, at baseline of the candidate biomarker, with respect to the onset, during follow-up, of a cardiovascular event: either coronary events or cerebrovascular stroke or lower limb arteriopathy.

    Measured: Day 0

  2. measurement of the candidate biomarker

    measurement, at baseline of the candidate biomarker, with respect to the onset, during follow-up, of a cardiovascular event: either coronary events or cerebrovascular stroke or lower limb arteriopathy.

    Measured: during the intervention/procedure/surgery

Secondary outcomes (2)
  1. evolution of clinical and biological parameters involved in atherothrombosis

    Pathophysiological mechanisms involved in atherothrombosis will be investigated using biomarkers addressing specific pathways: lipid metabolism, inflammation, endothelial reactivity, myocardial function. For a given new biomarker, its transferability to a clinical lab will be evaluated by its analytical performances and its possible adaptation to a semi-automated platform.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Diseases, run by University Hospital, Toulouse 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 2 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: looking for participants now, as of the sponsor's last update on 19 Mar 2026. 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?

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?

Contact Jean Ferrières, MD PhD (562323728 ext. 0033, ferrieres.j@chu-toulouse.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

measurement of the candidate biomarker (time frame: Day 0). 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 19 Mar 2026.
