New Study Shows PuraPly® Antimicrobial Positively Impacts Course of Healing Across Variety of Wound Types

Canton, MA, March 4, 2019 – Organogenesis Holdings Inc. (Nasdaq: ORGO), a leading regenerative medicine company focused on the development, manufacture and commercialization of product solutions for the Advanced Wound Care and Surgical and Sports Medicine markets, today announced that a new case series published in Plastic and Reconstructive Surgery - Global Open suggests PuraPly® Antimicrobial (PuraPly AM) positively affects the course of healing in a variety of complex, chronic wounds that were previously unresponsive to treatment.

The case series, "Use of Native Type I Collagen Matrix Plus Polyhexamethylene Biguanide for Chronic Wound Treatment" was conducted by Alisha R. Oropallo, MD, FACS, APWCA, et al, of Northwell Health Department of Surgery in Lake Success, New York. Dr. Oropallo tested the efficacy of PuraPly AM – referred to as PCMP in the study – in managing pressure ulcers, surgical wounds, venous ulcers, diabetic ulcers, and other types of wounds.

"The purpose of this case series was to assess the extent to which PuraPly AM helped meet wound-specific treatment goals on wounds that had not responded to conventional therapies, likely due to bioburden," said Dr. Oropallo. "Our findings show that Puraply AM indeed appears to positively impact the course of healing across a variety of complex chronic wounds, resulting in a wound environment that is conducive to wound area reduction and complete wound closure. We shared results of two subsets of wounds in this study at the 2018 Symposium on Advanced Wound Care."

Of the 41 wounds studied, 73% demonstrated a reduction in wound area at 12 weeks. Thirty-seven percent of the wounds studied achieved complete wound closure, with a mean time of 6.7 weeks to complete closure.

"This case series confirms what many clinicians already know firsthand: PuraPly AM is an innovative and important technology in the fight against non-healing wounds," said Gary S. Gillheeney, Sr., President and CEO of Organogenesis. "Given the tremendous burden these wounds impose on patients and the healthcare system, we are proud to offer a product that helps clinicians address a critical barrier to wound healing."

"An increasing body of clinical evidence demonstrates that appropriate use of PuraPly AM can lead to improved wound healing outcomes, which should allow patients to achieve a better quality of life in a shorter time frame," said Shabnam Vaezzadeh, MD, MPA, Vice President of Global Medical & Clinical Affairs for Organogenesis. "We are pleased that so many respected clinicians are conducting research on PuraPly AM and sharing their clinical outcomes with the wider medical community."

Organogenesis Holdings Inc. sponsored the case series.
