About this study

Official title: Bridged Vacuum Assisted Closure (VAC) With Compression vs. Compression Therapy in the Management of Venous Leg Ulcers: A Prospective Randomised Controlled Trial

This study randomises patients with venous leg ulcers, to be managed either using conventional compression bandages or a bridged vacuum assisted closure system under compression.

Read the detailed description

Venous ulcers are characterised by a cyclical pattern of healing and recurrence, with recurrence rates between 45 and 70% at one year. Venous leg ulceration has been identified as a common source of morbidity and reduced quality of life, especially in the elderly population. Non-healing ulcers place the patient at a much higher risk for lower extremity amputation.

Compression therapy is currently recognised as the main treatment for venous leg ulcers. External compression is applied as a therapy for venous leg ulcers, in an attempt to reverse the increased hydrostatic pressure in the veins.

The application of negative pressure to successfully treat and aid in the healing of open wounds has been studied extensively for decades, demonstrating favourable clinical results. However, there is a lack of evidence in the literature regarding the use of VAC in venous ulcers.

The combination of negative pressure therapy and compression therapy is theorized to provide the benefits of both individual therapies. As such, the utilization of the Bridge VAC under a compression dressing is expected to expedite the healing of venous ulcers.

The investigators aim to randomise patients with venous ulcers to either be managed using conventional compression dressings or combined bridge vacuum assisted closure with compression dressings.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bridged V.A.C.® with compression therapyDevice

    Patients randomised to receive Bridge VAC with compression dressings will be managed using ActiV.A.C. Therapy unit, with a continuous pressure of 125mmHg. A V.A.C.® Granufoam™ Bridge Dressing will be used instead of the tube connector. A Coban™ Lite compression dressing will be placed over the VAC dressing. The Bridge connector of the VAC will be used to tunnel underneath the Coban™ Lite till the upper edge of the dressing.

  • Conventional Compression TherapyDevice

    Patients randomised to receive compression dressings will be managed using Coban™ Lite compression dressings with underlying non-adherent wound contact layer (WCL) dressings. Under the supervision of the investigating clinician, the dressings will be applied by a wound care specialist nurse and changed once to three times per week (depending on amount of exudate), until full ulcer healing or up to 12 weeks.

What is being measured

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

  1. Time to healing

    The time taken for complete closure of the index ulcer or till the wound is judged suitable for skin grafting

    Measured: 12 weeks

Secondary outcomes (2)
  1. Proportion of ulcers healed

    The proportion of index ulcers fully healed

    Measured: 12 weeks

  2. Ulcer recurrence

    Wound recurrence rates at six weeks, and three, six and 12 months of follow-up

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Bridged V.A.C.® with compression therapy and Conventional Compression Therapy in people with Varicose Ulcer, run by Western Vascular Institute, Ireland at 1 site in Ireland.

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 4 inclusion and 15 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 4 Aug 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 Ireland. 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?

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?

Time to healing (time frame: 12 weeks). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2021.
