About this study

Official title: Evaluation of Intermittent Pneumatic Compression (IPC) of the Lower Limbs Associated With Elastic Stockings (ES) Compared to ES Alone on Venous Thromboembolism Incidence in Patients With High Bleeding Risk Hospitalized in Intensive Medical Care Units

This multicentre open-label randomized parallel-group trial aims to evaluate the association intermittent pneumatic compression + elastick stockings versus elasting stockings alone on symptomatic or asymptomatic venous thromboembolism incidence, evaluated systematically at day 6 (+/-2days), in patients hospitalized in intensive care units and with high bleeding risk.

Read the detailed description

Background: Venous thromboembolism is a leading cause of morbi-mortality for patients hospitalized in intensive medical care units. Nevertheless, few studies evaluating prophylactic methods exist. Data from these studies demonstrate however that unfractionated heparin and low molecular weight heparin are effective to reduce the incident rate of asymptomatic deep venous thrombosis (DVT) of the lower limbs by 50 % compared to the absence of prophylaxis. Rate of asymptomatic DVT remains about 15 %. When the bleeding risk is high, drug prophylaxis with anticoagulants is contra-indicated, and mechanical devices are recommended: elastic stockings (ES) alone or associated with intermittent pneumatic compression (IPC). However, mechanical devices have not been systematically evaluated in intensive medical care units.

Objective:

To compare the association IPC + ES to ES alone in patients with high bleeding risk and hospitalized in intensive medical care units, on symptomatic or asymptomatic venous thromboembolism incidence, evaluated systematically at day 6.

Design: Multicentre open-label randomized parallel-group trial with blinded evaluation of outcomes, and an inclusion period of 24 month. Brest CIC (Centre d'Investigations Cliniques, research center) coordinates this multicentre trial.

Outcomes:

The primary endpoint is a combined criterion (blindly evaluated) between day 1 and day 6:

  1. Non fatal symptomatic venous thromboembolic event (objectively confirmed) between day 1 and day 6,
  2. death due to a pulmonary embolism between day 1 and day 6, and 3) asymptomatic DVT (distal or proximal) detected by ultrasonography systematically done at day 6.

Patients number:

CIREA 1 : Assuming a DVT frequency of 15 % in the control group (ES alone) , we calculated that 356 patients will be required for the study to have 80% power to detect a 60% reduction in the relative risk with a two-sided alpha level of 5%. Because of about 20 % deaths in the first days, we decide to increase the number at 392 subjects.

Statistical analysis: Efficacy analysis is performed on an 'intention-to-treat' basis. The frequencies of the combined primary outcome at day 6 are compared between groups using an exact one-sided Fischer test. Adjustment for stratification variables used Cochran-Mantel-Haenszel test. Relative risk and absolute risk reduction are computed with their 95% CIs. A logistic regression model is used to take into account potential imbalance in baseline characteristics.

What is being measured

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

  1. Combined criterion evaluated at day 6 ± 2 days after randomization:symptomatic venous thromboembolic event, non fatal, objectively confirmed,Death related to PE,Asymptomatic DVT of the lower limbs detected by CUS on day 6 ± 2 days.

    Measured: 6 days (+/- 2 days)

Secondary outcomes (1)
  1. Symptomatic thromboembolic events occurred between day 6 and day 90, and total mortality at 1 month and 3 months.

    Measured: 6 days to 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Intermittent pneumatic compression of the lower limbs in people with High Bleeding Risk and Hemorrhage, run by University Hospital, Brest at 10 sites 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 10 inclusion and 8 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: finished, as of the sponsor's last update on 3 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites 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.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Combined criterion evaluated at day 6 ± 2 days after randomization:symptomatic venous thromboembolic event, non fatal, objectively confirmed,Death related to PE,Asymptomatic DVT of the lower limbs detected by CUS on day 6 ± 2 days. (time frame: 6 days (+/- 2 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 NCT00740844, which also lists 1 linked publication.

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 3 Dec 2025.
