Characterization of Exosomes Platelets-released (EXOPLT)

March 7, 2024 updated by: Centro Cardiologico Monzino
Extracellular vesicles (EVs) play a key role in cell-to-cell communication. They are small vesicles that contain rich molecular cargo. Recently, they have been proposed as biomarkers for clinical diagnostics. EVs include three classes: small EVs (exosomes), large EVs (microparticles), and apoptotic bodies. Platelet-derived EVs (PEVs) are the most abundant class in human blood and can actively participate in numerous physiological and pathological processes. The information about the role of platelet exosomes in cardiovascular disease and the effect of antiplatelet agents on their release and content is very limited.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study is a multicentre, observational. We plan to enrol 54 subjects from Centro Cardiologico Monzino IRCCS, and 121 buffy coat related to 121 subjects from Centro Trasfusionale Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico. biographical and anthropomorphic data will be recorded, a fasting blood venous sample (from ante-cubital vein) will be collected for the haematochemical analyses and for research samples.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Characterization of exosomes released by activated platelet by Nanoparticle Tracking Analysis (NTA) and proteoma analysis
Time Frame: 36 month
36 month
Characterization of exosomes released by activated platelet and exposed to platelet inhibitors by NTA and proteoma analysis
Time Frame: 36 month
36 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Platelet exosome profile emerged by NTA and proteoma analysis will be related with the "biographical" and "anthropometric" data of the subjects.
Time Frame: 40 month
40 month

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 8, 2021

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
