Eligibility Criteria

18 Years - 40 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Has deep partial or full-thickness thermal burns ≥50% of the TBSA and fulfills the total grafting area requirement ranging from 288 cm2 up to 5,600 cm2, divided between two (or more) recipient sites.
  • Is expected to require multiple skin grafting procedures.
  • Is ≥18 years and ≤40 years of age at the time of enrollment.

5. Study Description

Brief Summary
The purpose of this research study is to test how well the investigational treatment, Engineered Skin Substitutes (ESS-W), works for covering and treating burn wounds. The areas of the body that are treated with ESS-W will be compared to similar areas treated with the patient's own skin (split-thickness skin autograft (AG)). A skin autograft (AG) will be performed by taking healthy skin from one area of the body and placing it on the burned area.
Detailed Description
This study is designed to evaluate the safety and efficacy of autologous engineered skin substitute (ESS-W) compared to conventional split-thickness AG for the treatment of extensive, deep partial- and full-thickness thermal burns. A matched and randomized burn site format will be used to evaluate the successful graft take on excised deep partial- and full-thickness burns when grafted with either 1) unmeshed ESS-W or 2) meshed AG (the current standard treatment of split thickness AG). This research study is divided into five study periods: (1) Screening Period of up to one week and (2) Pre-Grafting Period, which will last approximately 35-45 days, (3) Grafting Day(s), which are the day(s) on which grafts are applied (i.e., First Graft: Day 0 and the optional subsequent Grafting Day i.e., Second Graft: Day 0), (4) Post Grafting Observation Period, which begins with 28 days follow-up after each Grafting Day(s), and continues till Post-Operative Month (POM) 6 from the last Grafting Day, and (5) Anecdotal Observation Period

Autologous Engineered Skin Substitute
Other Intervention Name(s)
ESS-W
Intervention Description
The total burn wound area covered will range from 288 cm^2 to 5,600 cm^2 (based on availability of matched-pair burn sites of similar area and depth) and this total grafting area will be divided equally for treatment with ESS-W and AG. ESS-W will be applied to the appropriate recipient site, according to the randomization schedule, by the surgeon using two pairs of forceps. Sufficient ESS-W sheets will be used to cover the recipient site. The ESS-W grafts will be stapled in place.
Intervention Type
Drug
Intervention Name(s)
Split-Thickness Autograft (AG)
Other Intervention Name(s)
Split-thickness skin grafts (STSGs)
Intervention Description
The total burn wound area covered will range from 288 cm^2 to 5,600 cm^2 (based on availability of matched-pair burn sites of similar area and depth) and this total grafting area will be divided equally for treatment with ESS-W and AG. The AG regimen occurs in stages, beginning with excision of the burned skin, followed by temporary wound coverage (e.g. cadaveric skin allografts, porcine xenograft, synthetic or biologic dressings or medical devices) to achieve wound homeostasis, and completed by permanent wound closure using autologous skin.
