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.

Further study details as provided by Systagenix Wound Management:

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
    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.

Secondary Outcome Measures:
  • Reduction in wound area and cost effectiveness [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    The relative reductions in wound surface area from baseline over twelve weeks of treatment.

Estimated Enrollment: 250
Study Start Date: July 2013
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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
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
Experimental: Promogran and Low EPA
Wounds with low EPA will be treated with Promogran and covered with a secondary which is standard of care
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
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
Device: Tielle
Tielle is a hydropolymer foam dressing that is designed to provide optimal wound healing
Active Comparator: Low EPA and standard of care
Low EPA wounds will be treated with the standard of care for diabetic foot ulcers.
Device: Tielle
Tielle is a hydropolymer foam dressing that is designed to provide optimal wound healing
