A Study to Evaluate the Efficacy of Microlyte Matrix in the Management of Donor Site Wounds
- Conditions
- Wounds and Injuries
- Interventions
- Device: Microlyte® Matrix
- Registration Number
- NCT05439746
- Lead Sponsor
- Imbed Biosciences
- Brief Summary
A study to to evaluate the efficacy of Microlyte® Matrix by demonstrating its superiority to the standard of care in the healing of donor site wounds in patients requiring split-thickness grafting, as well as to assess the occurrence of donor site wound infection, allergic reaction, pain and itching, and scarring at 12 weeks, assessed by patients using the Patient and Observer Scar Assessment Scale (POSAS).
- Detailed Description
The proposed study is a randomized, controlled, open-label clinical trial to assess the efficacy in wound healing of the FDA 510k cleared Microlyte® Matrix (K153756) in surgically created partial thickness donor site wounds \> 100 cm2 in size on patients and harvested at 12/1000th inch requiring split-thickness skin grafting. Subjects are expected to be hospitalized as in-patients for approximately 7 days following initial donor site surgery. Study visits conducted after hospital discharge must be conducted as out-patient clinic visits.
Each wound will be divided into proximal and distal halves with one half randomized to receive Microlyte® Matrix. Kaltostat/Tegaderm will be used as the control. Thus, each patient is their own control removing the potential variability of the depth of donor site wounds between patients as a confounding factor.
Microlyte® Matrix is a FDA-cleared (K153756) antimicrobial dressing manufactured by Imbed Biosciences, Inc. (Madison, WI), which is an ISO 13485 certified/FDA QSR compliant facility. It is indicated for the management of partial and full thickness wounds including pressure ulcers, venous stasis ulcers, diabetic foot ulcers, first and second-degree burns, abrasions and lacerations, donor sites and surgical wounds.

Group Intervention Description Matrix Comparison Microlyte® Matrix Qualified subjects are randomly assigned Microlyte Matrix in an open label fashion to half of a randomized similar depth donor site areas within a subject and determining percent healing at Day 14.
- Primary Outcome Measures
Name Time Method Percentage of donor site wound closure Day 14 post-op Therefore, assessment of the percentage wound closure at the time of primary outcome assessment (14 days) provides a very reliable method for detection of differences between groups. Digital photography and Image-J analysis allow for blinded assessment of primary outcome.
- Secondary Outcome Measures
Name Time Method Percentage of donor site wound closure Day 7 post-op Signs of infection or allergic reactions, pain, and pruritus assessed during each study visit.
Durability of wound closure, assessed by percentage of wound closure 12 weeks Wound Closure ranges from 0%-100% with 0% being no wound closure occurring and 100% being full closure
Pain, itching, and scarring, assessed by patients using the Patient and Observer Scar Assessment Scale (POSAS). 12 weeks POSAS Scale is a series of questions with answers ranging from 1-10, with 1 dictating few or negligible differences from normal skin, and 10 being unimaginable scar difference from normal skin.
Signs of infection or allergic reactions, pain, and pruritus 12 weeks
