Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The comparator control for the study is autografting, the current standard of care procedure for the treatment of severe burns, which involves the removal of healthy skin from an uninjured site on the patient and using it to cover the original burn wound to achieve complete and durable wound closure.
After surgical preparation of the wound bed, subjects will receive approximately 100 square centimeters of realSKIN at a predesignated wound site and separately, autografting at an alternate site, per the standard of care, in accordance with the randomization schedule.
Thus, each patient represents both the experimental and control group, to be evaluated in isolated but comparable settings. The use of an intra-patient comparator allows for a matched control to eliminate significant underlying differences, including immunologic, physiologic, and scarring variable inherent in this patient population that may impact wound healing at the treatment sites.
After surgical excision to remove nonviable tissue or previously applied temporary wound dressings, two wound treatment sites of comparable area and depth will be identified.
Treatment assignment will be randomized to receive either realSKIN or a surgically harvested autograft. The pre-identified treatment sites must each be a wound area of comparable depth that is not contiguous (e.g., "sharing a common border or touching") to ensure the interpretability of the efficacy results.
Additionally, two unaffected areas of the patient's intact, healthy skin will be prospectively identified to provide sources of autografts for the control site and realSKIN treatment site (e.g., patient skin harvest sites.) These pre-identified regions may be in the same anatomic area or from two separate but comparable areas, depending on the amount of intact native patient skin available.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Skin Xenotransplant
After surgical preparation of the wound beds, subjects will receive approximately 100 square centimeters of realSKIN® at one site, and autograft at the other site, per the standard of care, in accordance with the randomization schedule.
Skin Xenotransplant
realSKIN® is a live biotherapeutic, bi-layered, split-thickness, membranous, skin xenotransplant wound dressing manufactured from living porcine skin sourced from genetically engineered, alpha-1,3-galactosyltransferase knock-out (GalT-KO) porcine (Sus scrofa) donors under aseptic conditions.
realSKIN® is topically applied to a surgically prepared wound bed via sutures or staples and may be trimmed to fit the shape and size of the wound area.
Autograft
The comparator control for the study is autografting: the current standard of care procedure for the treatment of severe burns involves the removal of a sheet of healthy skin from an uninjured site on the patient and using it to cover the original burn wound to achieve complete and durable wound closure.
Autograft(ing)
Autograft(ing) is the current standard of care procedure for the treatment of severe burns. The procedure involves the removal of a sheet of healthy skin, i.e. autologous (self) skin harvesting, from an uninjured site on the patient and using it to cover the original burn wound.
