Osiris Therapeutics Announces a New Product: Stravix

A viable cryopreserved human placental tissue for surgical applications

COLUMBIA, Md.--()--Osiris Therapeutics, Inc. (NASDAQ: OSIR), the leading cellular regenerative medicine company focused on developing and marketing products to treat conditions in wound care, orthopaedics and sports medicine, announced today the launch of Stravix, a cryopreserved human placental tissue designed to address surgical needs for soft tissue repair.

The two billion dollar U.S. soft tissue reinforcement market consists of utilizing grafts for the surgical treatment of a broad range of indications1. While synthetic grafts have been traditionally used, biologic tissue grafts have offered better results with fewer post-operative complications. It is broadly published that surgical reconstruction procedures benefit from products that provide structural support, and reduce scarring and inflammation. Placental tissues as a cover have such properties;2 however, the majority of the currently used placental products are dead, dehydrated amniotic membranes lacking sufficient tensile strength and activity. Stravix was developed as a pliable allograft cover with tensile strength that is ten times greater than amniotic membranes alone and designed to offer durability, elasticity, and conformability for surgical procedures.3,4 In addition, Stravix retains the properties inherent to the native fresh tissue as a result of Osiris’ proprietary cryopreservation process, BioSmart®.

“Osiris plans to collect scientific and clinical data supporting the use of Stravix,” said Alla Danilkovitch, Ph.D., Chief Scientific Officer. “The ideal allograft should not only preserve the original characteristics of the tissue beneficial for natural repair but also have properties and ease of application needed for complicated surgeries; Osiris has achieved this with Stravix.”

About Stravix

Stravix is a viable cryopreserved human placental tissue comprised of amniotic and connective layers of umbilical tissue that has been developed as a cover specifically for surgical procedures. It retains native components of the tissue including collagen and hyaluronic acid rich extracellular matrix, cytokines, fibroblasts, growth factors, viable endogenous mesenchymal stem cells and epithelial cells. Stravix conforms to the site of injury, requires minimal preparation prior to use and is stored at -75°C to -85°C.
