About this study

Official title: A Prospective, Multicenter, Open Label, Randomized, Controlled Clinical Study Evaluating the Effect of NovoSorb ® SynPath™ Dermal Matrix Compared to Standard of Care (SOC) In the Treatment of Nonresponsive, Chronic Diabetic Foot Ulcers.

The study will evaluate the efficacy of SynPath™, a synthetic dermal matrix, in the treatment of diabetic foot ulcers in subjects with diabetes mellitus versus Standard of Care treatment.

Half the subjects with be treated using SynPath™ while the other half will receive Standard of Care treatment

Read the detailed description

One hundred and thirty-eight (138) subjects with chronic Diabetic Foot Ulcers ranging in size from 1cm2 to 25cm2 will be randomized 1:1 to either SynPath™ or Standard of Care after the completion of a 14 day screening/run-in period. Following the of run-in period the subjects with a 'hard to heal' or chronic, (>4 weeks) nonresponsive Wagner Grade 1 or 2 diabetic foot ulcer will be randomized to receive either SynPath™ or SOC treatment. Both treatment groups will require subjects to use off-loading device.

What is being measured

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

  1. Percentage of ulcer closed at 12 weeks

    Complete wound closure was defined as 100% re-epithelialization of the ulcer surface without drainage or dressing requirements confirmed at 2 consecutive study visits 2 weeks apart

    Measured: 12 weeks

Secondary outcomes (6)
  1. Percentage of ulcers that achieved 50% or greater closure rate within 6 weeks

    The percentage of ulcers that achieve 50% or greater closure

    Measured: 6 weeks

  2. Comparison of closure rates for each treatment group

    Comparison of rates of wound closure between Standard of Care and SynPath

    Measured: 12 weeks

  3. Percent Wound Area Reduction(PWAR) over 12 weeks

    The Change in percentage wound reduction(PWVR) over 12 weeks for each treatment group

    Measured: 12 Weeks

  4. Cost of treatment in each treatment group

    Calculation of cost of treatment including number of device applications for each treatment group

    Measured: 12 weeks

  5. Change in reported Pain Levels between each treatment group

    Change in subject reported pain levels using the 0-10 Numerical Pain Scale

    Measured: 12 weeks

  6. The type and number of serious adverse events experienced

    Comparison of the type and number of serious adverse events experience for each treatment group

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing SynPath Acellular Dermal Matrix plus Off-loading Device and Wound Dressing composed of 90% collagen and 10% Alginate plus Off-loading Device in people with Diabetic Foot and Chronic Foot Ulcer, run by PolyNovo Biomaterials Pty Ltd. at 7 sites in United States.

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 17 inclusion and 26 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 5 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. 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 was stopped early (reason given: After review of study data, sponsor determined wound bed preparation prior to product application was not being followed. A new study will be considered with clearer definition of wound bed preparation and strict adherence to the steps for use.). Results are not available in the source record.

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?

Percentage of ulcer closed at 12 weeks (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 5 Mar 2024.
