Osiris Announces Implementation of Prestige Lyotechnology℠ Preservation Method Allowing Ambient Storage of Living Tissues

COLUMBIA, Md., June 04, 2018 (GLOBE NEWSWIRE) -- Osiris Therapeutics, Inc. (OTC Pink:OSIR), a regenerative medicine company focused on developing and marketing products for wound care, orthopedics, and sports medicine, announced today the implementation of Prestige Lyotechnology for manufacturing of commercial products.

In 2017, Osiris announced the development of Prestige Lyotechnology, a preservation technique for ambient storage of living tissues (see In April 2018, studies describing properties of viable lyopreserved tissues were presented at scientific conferences including the Annual Symposium on Advanced Wound Care (SAWC) and Wound Healing Society (WHS) (see 

Cryopreservation is the conventional method for long-term storage of living cells and tissues. However, this method requires ultra-low temperature (below –80 Celsius degrees) equipment for storage and shipment, which creates a barrier to widespread use. We believe Prestige Lyotechnology will allow for storage and shipment of living tissue, including our products, at room temperature. We expect this technology to have practical significance for both scientific and clinical applications, because it is designed to eliminate the need to preserve and transport our products at constant ultra-low temperatures.

Osiris is pleased to report validation, testing and up-scaling of Prestige Lyotechnology for manufacturing of our products. We expect our GrafixPL PRIME™ product to be our first commercially available product in the lyopreserved configuration. The structural matrix, growth factors, and cell viability of GrafixPL PRIME are equivalent to that of Grafix PRIME®, a cryopreserved placental membrane, but without the constraints of ultra-low temperature storage (see

Grafix® and GrafixPL® products are cryopreserved and lyopreserved placental membranes, respectively, that retain the extracellular matrix, growth factors, endogenous cells, including neonatal mesenchymal stem cells, and fibroblasts of the native tissue, all of which are beneficial in supporting natural wound repair. Both configurations are flexible and are conforming wound covers designed for direct application on hard-to-treat acute and chronic wounds, including, but not limited to, diabetic foot ulcers, venous leg ulcers and thermal burns. The two configurations will also be comparably priced, depending on size of the graft, with list prices ranging from $495-$3,000.

"We are very pleased with the progress of our implementation of Prestige Lyotechnology, which we believe is another outstanding achievement of the company," said Jason Keefer, Interim Chief Executive Officer. "With Prestige Lyotechnology and GrafixPL PRIME, Osiris believes the challenges of 'cold chain' storage and distribution of living tissues will be eliminated, which could allow our products to reach more physicians and help more patients in need.”
