Treatment With Synthetic Hybrid-Scale Fiber Matrix
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. Restrata®: 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.
Treatment With Standard of Care
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. Wound Dressing: Alginate or Foam wound dressing is intended to manage wounds.

SECONDARY outcome

Timeframe: 12 weeks

Population: Per protocol population including participants that completed the primary study endpoint/treatment period without withdrawal.

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.
