PREvention of VENous Thromboembolism In Hemorrhagic Stroke Patients
A Phase 3 study testing Enoxaparin and Graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization in people with Hemorrhagic Stroke and Venous Thromboembolism, run by University Of Perugia at 1 site in Italy.
Trial summary
Patients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%).

About this study
Patients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%). Graduated compression stockings alone are ineffective in preventing deep vein thrombosis in patients with ischemic or hemorrhagic stroke. Less clear is the role of anticoagulation in the prevention of venous thromboembolism in patients with ICH because the use of anticoagulants may cause an enlargement of the hematoma. In a multicenter, randomized trial, the investigators will assess the efficacy and safety of enoxaparin in the prevention of venous thromboembolism in patients with spontaneous intracerebral hemorrhage. Enoxaparin (40 mg once daily) or standard therapy (graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization) will be given subcutaneously for not less than 10 days beginning after 72 hours from stroke onset.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Patients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%). Graduated compression stockings alone are ineffective in preventing deep vein thrombosis in patients with ischemic or hemorrhagic stroke. Less clear is the role of anticoagulation in the prevention of venous thromboembolism in patients with ICH because the use of anticoagulants may cause an enlargement of the hematoma. In a multicenter, randomized trial, the investigators will assess the efficacy and safety of enoxaparin in the prevention of venous thromboembolism in patients with spontaneous intracerebral hemorrhage. Enoxaparin (40 mg once daily) or standard therapy (graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization) will be given subcutaneously for not less than 10 days beginning after 72 hours from stroke onset.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Enoxaparin and Graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization in people with Hemorrhagic Stroke and Venous Thromboembolism, run by University Of Perugia at 1 site in Italy.
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 3 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: stopped early, as of the sponsor's last update on 10 Sep 2021. 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 Italy. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants With Symptomatic and Asymptomatic Venous Thromboembolism (time frame: 10 days). 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 NCT01573169, which also lists 3 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 10 Sep 2021; AzTrials last refreshed its copy on 8 Nov 2026.
