Interest of Thromboelastography (ROTEM) as a Biomarker of Revascularisation in Stroke
An observational study of Stroke, run by University Hospital, Caen at 1 site in France.
Trial summary
Revascularisation using recombinant tPA is the reference treatment of stroke. However, the efficacy of fibrinolysis is about 50%. Several factors, including the size of thrombus, have been associated with revascularisation efficacy. Read more about this study

Study population: All patients meeting the eligibility criteria will be invited to participate in the study . Patients will be recruited to emergencies CHU Caen and Saint Joseph Hospital. The goal is to recruit patients with neurological defect consistent with a neurovascular pathology eligible for thrombolysis with tPA. With the admission of patients, blood samples are routinely made . For this study, the investigators will add one citrated 5 mL tube. An information letter and consent form will be given to the patient.
Who may be able to join
- Patient (> 18 years) with a neurological deficit compatible with a neurovascular pathology eligible for fibrinolysis rtPA and having a proximal occlusion of the middle cerebral artery (segment M1 / M2) or basilar trunk objectified brain imaging (MRI angiography or angio CT).
Who cannot join
- Any patient with major comorbidity, a pathology of hemostasis or anticoagulant treatment (vitamin K antagonist (VKA), direct oral anticoagulant).

About this study
Revascularisation using recombinant tPA is the reference treatment of stroke. However, the efficacy of fibrinolysis is about 50%. Several factors, including the size of thrombus, have been associated with revascularisation efficacy.
The aim of this prospective study is to evaluate ex vivo the effect of tPA in patients with stroke with thromboelastography and to correlate results with the clinical outcome of patients. Results may predict revascularisation in patients with stroke.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 15 Sep 2016. 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 Yohann REPESSE, MD PhD (+330231063315, repesse-y@chu-caen.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluation of revascularisation 24 hours after tPA injection using CT scan or MRI (time frame: 24 hours). 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?
