PolarityTE Announces Data from Head-to-Head Burn Study Demonstrating Graft Take and Wound Closure with SkinTE Treatment

PolarityTE, Inc. PTE, a biotechnology company developing and commercializing regenerative tissue products and biomaterials, today announced that data from its Head-to-Head Burn trial was published in the Journal of Burn Care & Research. This abstract was accepted for a podium presentation at the American Burn Association Meeting, which was cancelled due to the COVID-19 pandemic. Eight patients with deep-partial/full thickness burns had a portion of their wounds treated with SkinTE™, an autologous homologous skin construct (AHSC), and the remainder of their burn treated with split-thickness skin grafting. AHSC-treated wounds had graft take and achieved closure by their last follow-up with a single application. There were no AHSC treatment related adverse events. These encouraging data are being used to design a larger burn trial and the Company continues to work with several KOLs to finalize a study protocol.

"We are pleased with the outcome of the study and believe this provides further evidence that SkinTE is a viable option for patients with partial and full thickness burns as physicians look to augment their treatment armamentarium outside of traditional skin grafts," said Nikolai Sopko, MD, PhD, Chief Scientific Officer at PolarityTE. David Seaburg, Chief Executive Officer at PolarityTE added, "We remain committed to generating robust scientific data for the use of SkinTE as we know those data provide healthcare professionals with valuable incremental evidence as they evaluate where SkinTE best fits into their practices."

About PolarityTE®

PolarityTE is focused on transforming the lives of patients by discovering, designing and developing a range of regenerative tissue products and biomaterials for the fields of medicine, biomedical engineering and material sciences. Rather than manufacturing with synthetic and foreign materials within artificially engineered environments, PolarityTE manufactures products from the patient's own tissue and uses the patient's own body to support the regenerative process. From a small piece of healthy autologous tissue, the company creates an easily deployable, dynamic and self-propagating product designed to regenerate the target tissues. PolarityTE's innovative method is intended to promote and accelerate growth of the patient's tissues to undergo a form of effective regenerative healing.

About SkinTE™

SkinTE is a human cellular and tissue-based product derived from a patient's own skin intended for the repair, reconstruction, and replacement of skin tissue.

SkinTE is intended to be used by physicians or other appropriate healthcare providers for homologous uses of skin tissues/integument. Patients who have suffered from an event, disease, process or acquired deficit that results in the functional loss or void of skin/integument systems can receive SkinTE as an adjunct and/or in place of split-thickness skin grafting, full-thickness grafting, temporizing skin coverage and/or skin substitute products. SkinTE is for autologous use only. Aseptic technique during harvest and deployment of SkinTE is mandatory. SkinTE is marketed as an HCT/P regulated by the FDA solely under Section 361 of the Public Health Service Act and 21 CFR 1271.
