About this study

Official title: EPC Silver Wound Gel (EPC-123) Feasibility Clinical Study: Prospective, Single-arm, Repeated Measures Study of EPC Silver Wound Gel in the Management of Locally Infected Diabetic Foot Ulcers

The objective of this single-arm feasibility study is to investigate the safety and impact of the topical EPC Silver Wound Gel (EPC-123) in the management of diabetic foot ulcer wounds not progressing under the current standard of care.

Read the detailed description

The objective of the proposed work is 1) to monitor clinical safety of EPC Silver Wound Gel on diabetic foot ulcers, 2) to evaluate the clinical impact of EPC Silver Wound Gel in foot ulcer progression in conjunction with the standard of care 3) to quantify the changes within the wound bacterial environment as it impacts wound healing and 4) to evaluate subjective patient and clinician outcomes: satisfaction, quality of life, perceived benefit, and compliance.

Consenting subjects who qualify for enrollment will proceed with two, weekly, visits related to screening. If screen passed, ie. under the current standard of care no progression of the diabetic foot ulcer is observed in accordance with validated diabetic foot ulcer classification metrics, then the subject will proceed with two weeks of study period where twice weekly clinic and twice weekly intermediate home-based care. This may be followed by an additional two weeks of study period, if warranted in accordance with best practice, with once weekly clinic and intermediate home care visits. In total there will be up to 9 clinic visits (minimum 7 clinic visits up to 9 clinic visits) in 6 weeks (screening and trial visits; minimum 4 weeks up to a maximum of 6 weeks).

What participants receive

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

  • EPC Silver Wound GelDevice

    Re-application of EPC-123 will occur within 48 hours of the initial application. Secondary dressings will be selected at the discretion of the clinician or home care provider, based upon best practice guidelines for moisture management and will consist of a selection between the following secondary dressings: Mesorb® (Molnyke), Gauze, Cling (self-adherent gauze), or MediporeTM (3M). Application of EPC-123 will be executed at the Lawson Health Research Institute every second visit, where interim applications will be facilitated by home care. To support home care applications, a study kit will be provided to home care professionals inclusive of the EPC Silver Wound Gel, secondary dressings required, and instructions for removal/re-application.

What is being measured

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

  1. Incidence of intervention-related adverse events collected throughout the trial

    Clinical and/or biological adverse events will be reported over the intervention period. Severity of any adverse events will be graded.

    Measured: Up to 28 days

    Measured: Up to 42 days

  3. Progression the Diabetic Foot Infection (DFI) Wound Score during the intervention period compared with screening period under standard of care.

    Signs and symptoms of infection will be assessed using the 10-item DFI Wound Score system inclusive of semi-quantitative measurement of purulent discharge, non-purulent discharge, erythema, induration, tenderness, pain, warmth, size, depth, undermining.

The record says: finished, as of the sponsor's last update on 22 Sep 2023. 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 Canada. 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?

Incidence of intervention-related adverse events collected throughout the trial (time frame: Up to 28 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 NCT05243810, which also lists 7 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 22 Sep 2023.
