Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Treatment with Synthetic Hybrid-Scale Fiber Matrix

Treatment with Standard of Care

Arm Description

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.

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.

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

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.
Time to Wound Closure
The number of weeks from initial application of study treatment until complete re-epithelialization is first identified.
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.

Other Intervention Name(s)
Synthetic Hybrid-Scale Fiber Matrix
Intervention Description
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.
