Allogeneic Adipose Tissue Extract in Wound Treatment and Scar Maturation

This study will evaluate the effect of an allogeneic adipose tissue extract on wound healing and scar maturation. Thirty adult patients scheduled for skin graft surgery will be enrolled. Each patient will have two skin graft donor sites harvested. One skin graft donor site wound will be treated topically with the adipose tissue extract, applied immediately after harvesting and reapplied on Day 3, while the other skin graft donor site wound will receive standard care. The main outcome is the time to complete epithelialization of the wound, as confirmed by investigators and independent reviewers. Secondary measures include wound characteristics, scar formation and scar quality, and monitoring of adverse events, such as wound deterioration.

Cell-free preparate of human adipose tissue is intended to be used in the human body for its original purpose to supplement and replace local extracellular matrix deficiencies in soft tissue, including skin. The tissue product provides a temporary conductive environment into the injured area. This facilitates the ability of local cells to re-populate the damaged soft tissue and skin area, thereby enabling the deposition of extracellular matrix and repair of the tissue.
