PHASE I CLINICAL TRIAL

realSKIN™ is a live biotherapeutic, split-thickness, xenotransplantation skin product derived from specialized, genetically engineered (alpha 1,3 galactosyltransferase knockout [GalT-KO]), Designated Pathogen Free (DPF), porcine donors containing live (i.e., non-terminally sterilized) porcine cells, including endothelial cells of intact vasculature and those comprising the dermal and epidermal tissue layers.

 

realSKIN™ provides a temporary barrier against infection, helps prevent fluid loss, and helps restore the epidermal barrier prior to definitive wound closure with the placement of an autograft. realSKIN™’s inclusion of viable epithelial, epidermal, and porcine dermal cells permit revascularization of the wound bed, critical for efficient re-epithelialization and wound healing.

 

In our open-label, two-cohort, 3x3 dose-escalation clinical trial (XENO-001, NCT03695939) conducted at Massachusetts General Hospital, realSKIN™ was shown to provide the same temporary wound closure and temporary restoration of barrier function as the current standard of care in the treatment of severe and extensive deep-partial and full-thickness burn wounds requiring hospitalization, surgical excision, and skin grafting.

 

Over the two-year study period, realSKIN™ has demonstrated safety and tolerability in all patients treated, and its efficacy is indistinguishable from that of the Human Cadaver Allograft (HCA) active control.
