Diabetic Foot Ulcer Participants Assigned to Synthetic Hybrid-Scale Fiber Matrix (Restrata®)
Biweekly (every 2 weeks) application for either 12 weeks or until 100 percent epithelialization / wound closure (whichever occurs first)
Synthetic Hybrid-Scale Fiber Matrix: A synthetic absorbable skin substitute indicated for use in the local management of wounds. It is made of small synthetic fibers that are designed to be similar to the structure of human skin.
|
Diabetic Foot Ulcer Participants Assigned to Standard of Care
Weekly application for either 12 weeks or until 100 percent epithelialization / wound closure (whichever occurs first)
Standard of Care: To ensure off-loading, each patient will be fitted with an off-loading device based on the investigator's decision, e.g. a boot for forefoot and a heel protector for hindfoot. Patients is instructed on how to care for the surgical site, utilize an off-loading device, and keep the surgical site moist and clean. If the wound is dry, a hydrogel category dressing type should be used. If the wound has exudate, an alginate or foam dressing is recommended.

SECONDARY outcome
Timeframe: Weekly assessments for 12 weeks for DFU participants (16 weeks for VLU participants), or until 100 percent epithelialization, whichever occurs first.Population: Positive numbers represent increases and negative numbers to represent decreases
Wound area measurements will be made via a three-dimensional high resolution photo of the wound with automated measurements. Mean percent wound change will be calculated for each treatment arm/group with Week 1 as the baseline value. Change is calculated using the 2-week follow up visit after wound closure for wounds that achieved closure, or for wounds that did not achieve closure, the Week 12 wound area for DFUs and Week 16 wound area for VLUs.
