Development of a WNT Inhibitor for Regenerative Healing of Burn Injuries

ABSTRACT Burns represent one of the most traumatic and debilitating injuries affecting over million people in the United States Reparative processes occurring after acute burn injury ultimately result in fibrosis scarring In experimental systems WNT pathway activation promotes scarring while inhibition leads to regeneration We have identified pyrvinium SST an FDA approved anthelminthic drug as a potent inhibitor of WNT signaling Our preliminary studies in mouse wound models indicate that topical delivery of SST promotes regenerative wound healing increased tensile strength and reduced fibrosis after cutaneous injury The goal of this Phase I proposal is a concerted effort between StemSynergy Therapeutics Inc SSTI and Vanderbilt University to evaluate a novel class of small molecule CK agonists that promote regenerative healing reduced scarring of burn injuries with improved efficacy compared to SST Preliminary topical formulation and efficacy studies involving SSTI s lead CK agonists will be assessed in two well established animal models of regenerative healing Successful completion of these studies will allow us to evaluate and prioritize our CK agonists for more comprehensive formulation and efficacy studies in a Phase II application NARRATIVE The development of new therapies that reduce scar tissue formation following burn injuries has been a major challenge Herein we present the development of a new first in class therapeutic for treating burns that promotes regenerative healing over scar tissue The market and benefit to society for the successful development of this product is enormous
