To identify EPA wounds using WOUNDCHEK™ Protease Status diagnostic test, and to compare the healing outcomes of two treatment regimes (PROMOGRAN®, a protease modulating therapy and current standard of care) on chronic wounds with EPA. [ Time Frame: 4 weeks ]
An improved healing outcome for diabetic foot ulcers ulcers will be defined as the proportion of wounds which reach a minimum 50% percentage reduction in wound surface area over a four-week treatment period.

Reduction in wound area and cost effectiveness [ Time Frame: 12 weeks ]
The relative reductions in wound surface area from baseline over twelve weeks of treatment.
Reduction in wound area and cost effectiveness [ Time Frame: 12 weeks ]

The relative reductions in wound surface area from baseline over twelve weeks of treatment.

The relative cost effectiveness of both treatment regimes when they are targeted appropriately; PROMOGRAN®, a protease modulating therapy targeted to wounds with EPA and standard of care to wounds with LPA

WOUNDCHEK™ Protease Status Point of Care (POC) Diagnostic Test on DFU
WOUNDCHEK™ Protease Status Point of Care (POC) Diagnostic Test A Prospective, Multi Centre, Randomised, Clinical Study on Diabetic Foot Ulcers

The purpose of this trial is to determine if wounds with elevated protease activity (EPA) treated with targeted interventions such as protease modulating therapies can improve clinical and economic outcomes.

It is hypothesized that protease modulating dressings may provide significantly better clinical outcomes on EPA wounds over current standard of care.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Diabetic Foot Ulcers
  • Device: PROMOGRAN
    PROMOGRAN® is a protease modulating dressing, formulated as a bioresorbable amorphous open-pored matrix constructed of 45% oxidised regenerated cellulose (ORC) and 55% bovine collagen
  • Device: Tielle
    Tielle is a hydropolymer foam dressing that is designed to provide optimal wound healing
  • Experimental: Promogran and High EPA
    Wound with high EPA will be treated with promogran and covered with a secondary dressing that is standard of care
    Intervention: Device: PROMOGRAN
  • Experimental: Promogran and Low EPA
    Wounds with low EPA will be treated with Promogran and covered with a secondary which is standard of care
    Intervention: Device: PROMOGRAN
  • Active Comparator: High EPA and standrad of care
    Wounds with high EPA will get standard of care as in line with current practice as they is no other test currently available for EPA
    Intervention: Device: Tielle
  • Active Comparator: Low EPA and standard of care
    Low EPA wounds will be treated with the standard of care for diabetic foot ulcers.
    Intervention: Device: Tielle
