About this study

Official title: Echo-Doppler Assessment of the Occurrence of Asymptomatic Deep Vein Thrombosis (DVT) in Orthopedic Replacement Surgery Under Enoxaparine (PRENOXA)

The objectives of the study are:

  • Objective ultrasound: Determine the presence or absence of subclinical DVT in practicing ultrasound-Doppler Day7 and Day35, patients who underwent TKA or THA
  • Clinical objective To evaluate the efficacy and tolerability clinical Enox ® in these patients compared with the original drug Lovenox ®.

What is being measured

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

  1. Presence or absence of ultrasound findings in favor of asymptomatic DVT

    After orthopedic surgery, patients are put under LMWH thromboprophylaxis based but some patients may be carrying an asymptomatic DVT. so we'll try the distal venous thrombosis rate in these patients using Doppler ultrasound.

    Measured: Day 7 and 35

Secondary outcomes (1)
  1. To evaluate the efficacy and tolerability clinical Enox ® in these patients.

    Criteria for evaluating the effectiveness of Enox ®:

    • Onset or without clinical signs of deep vein thrombosis in clinical postoperative
    • Onset or without clinical signs of pulmonary embolism after surgery

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Enoxaparin in people with Deep Vein Thrombosis and Venous Thrombosis, run by Les Laboratoires des Médicaments Stériles at 1 site in Tunisia.

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 1 inclusion and 4 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 Nov 2015. 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 Tunisia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Presence or absence of ultrasound findings in favor of asymptomatic DVT (time frame: Day 7 and 35). 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 NCT01354704, 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 Nov 2015.
