About this study

Official title: Assessment of Wound Closure Comparing Synthetic Hybrid-Scale Fiber Matrix With Standard of Care in Treating Diabetic Foot Ulcer

Conditions: Diabetic Foot Ulcer
Being tested: Restrata®, Wound Dressing
Keywords: Synthetic Hybrid-Scale Fiber Matrix, Diabetic Foot Ulcer, Epithelialization
Medical subject headings: Diabetic Foot

What participants receive

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

Restrata®Device
Also called Synthetic Hybrid-Scale Fiber Matrix
Restrata® is a sterile, single use device intended for use in local management of wounds. Restrata® is a soft, white, conformable, non-friable, absorbable matrix that provides a moist environment for the body's natural healing process to occur. Restrata® is made from synthetic biocompatible materials and was designed to include a fibrous structure with high porosity, similar to native extracellular matrix.
Wound DressingDevice
Alginate or Foam wound dressing is intended to manage wounds.

Study groups in NCT04918784
Study group	Role	What they receive
Treatment with Synthetic Hybrid-Scale Fiber Matrix	Experimental	Diabetic foot ulcers will be treated by application of the Synthetic Hybrid-Scale Fiber Matrix. The synthetic matrix will be applied weekly or as needed based on the clinician discretion and ongoing wound assessment. Receives: Device: Restrata®
Treatment with Standard of Care	Active comparator	Diabetic foot ulcers will be treated by application of an appropriate dressing (foam or alginate dressing) to maintain wound moisture balance in the wound and changed daily. Receives: Device: Wound Dressing

What is being measured

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

Number of Participants With 100% Re-epithelialization
Primary outcome is number of participants with 100% epithelialization at 12 weeks of treatment as determined by investigator assessment of the ulcer and imaging.
Measured: 12 weeks

Secondary outcomes (3)

Change in Wound Area
The difference in wound area from baseline to 100% re-epithelialization or week 12 will be summarized for each treatment group in each arm. Wound sizes were documented by the investigator at baseline to end of the treatment period for each participant.
Measured: 12 weeks
Time to Wound Closure
The number of weeks from initial application of study treatment until complete re-epithelialization is first identified.
Measured: Up to 12 Weeks
Number of Treatment Applications
The number of study treatment applications including the initial application until 12 weeks or until complete re-epithelialization, whichever occurs first.
Measured: 12 weeks
