Evaluating Clopidogrel Resistance in Patients Undergoing Carotid Stenting

Official title: MULTIcentric Study About RESistance to CLOpidogrel in Dual Antiplatelet Therapy for Carotid Stenting

Run by IRCCS Policlinico S. Donato · NCT05566301 · Data updated 2026-11-12

This study is testing whether switching to a different medication called Ticagrelor can help patients who don't respond well to Clopidogrel during carotid stenting procedures.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old who are undergoing carotid stenting and have consented to participate in the study.

Probably not a fit

Patients who are underage, pregnant, or have carotid stenosis not suitable for stenting will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational multicentric study aims to assess the differences in outcomes between patients who respond to Clopidogrel and those who do not, specifically focusing on the use of Ticagrelor in non-responders undergoing carotid stenting. The study will collect clinical data, including patient demographics, cardiovascular risk factors, and laboratory results, to identify factors associated with Clopidogrel resistance. Patients will be followed up at multiple intervals post-procedure to monitor for major adverse cardiovascular events and bleeding complications. The goal is to improve understanding of antiplatelet therapy effectiveness in this patient population.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with carotid stenosis, potentially reducing adverse cardiovascular events.

How similar studies have gone: While studies on antiplatelet therapy exist, this specific approach to evaluating Clopidogrel resistance in carotid stenting is relatively novel.
