Osiris Therapeutics Wins Top Scoring Abstract at the 24th Annual Symposium on Advanced Wound Care

Three abstracts describing the science and initial clinical results of the Osiris Biosurgery product Grafix® to be presented at leading wound care conference

COLUMBIA, Md.--()--Osiris Therapeutics, Inc. (NASDAQ:OSIR) today announced that three abstracts describing the science and initial clinical evaluation of Grafix, a cellular wound care dressing, in the limb salvage and recalcitrant wound setting were accepted for presentation at the 24th Annual Symposium on Advanced Wound Care and Wound Healing Society. The abstract, “Characterization of novel human mesenchymal stem cell-containing skin substitutes for the treatment of wounds” by lead author Dr. Dana Yoo, was awarded the top score of all entries to the meeting as determined by a blinded review panel that evaluated submissions for their importance and relevance to the field of wound care research. Dr. Yoo will give a podium presentation on the subject in Session 41.1 on April 16.

Grafix is a living skin substitute comprised of a biologic membrane containing endogenous mesenchymal stem cells (MSCs) that is used to promote healing in chronic wounds, limb salvage procedures, and burns. Studies have demonstrated that Grafix contains the necessary components for optimal dermal repair including sustained expression of an array of growth factors and cytokines that limit inflammation and promote each phase of wound healing.

“Chronic wounds remain a debilitating and at times life-threatening problem for over 5 million people in the United States alone,” said Walter A. Conlan III, M.D., CWS, Medical Director of the Wound Healing Center at Osceola Regional Medical Center and Grafix investigator. “Research has shown that stem cells have the unique ability to provide trophic support and control unwanted inflammation, making them an ideal candidate in the chronic wound setting. At our center, we were able to safely close chronic wounds with Grafix that were otherwise unresponsive to advanced therapies. Grafix should be considered in the management of patients with chronic wounds that are non-responsive to conventional treatment.”

On April 16 (Session 41.2) Dr. Conlan will give a podium presentation entitled, “The use of a novel, human mesenchymal stem cell-containing skin substitute in the treatment of refractory wounds: a case series,” describing the performance of the product in patients with difficult to treat wounds that have failed at least one advanced therapy.

The abstract entitled, “Limb salvage utilizing a human mesenchymal stem cell-containing skin substitute: results of a case series in patients with diabetic foot ulcers” will also be presented in the poster session on April 15. This study demonstrated the utility of Grafix as a salvage treatment in patients with severe wounds who were at risk for amputation from diabetic foot ulcers.
