ThermoGenesis Signs Agreement With Biomet Biologics, Inc. To Produce Intra-Operative Autologous Fibrin Sealant

RANCHO CORDOVA, Calif., Aug. 3 /PRNewswire-FirstCall/ -- ThermoGenesis Corp. announced today that the Company entered into a development, license and supply agreement with Biomet Biologics, Inc., a wholly owned subsidiary of Biomet, Inc. . Biomet Biologics plans to combine ThermoGenesis’ protein harvesting technology with its currently offered and future autologous therapies to manufacture autologous fibrin sealant in a peri-operative setting. The product will feature a fibrinogen harvesting disposable in combination with Biomet Biologics’ Clotalyst(TM) System that can produce fibrin sealant from a patient’s own blood in less than 30 minutes. Fibrin sealant is an adhesive gel used by surgeons to stop bleeding and bond tissue.

“We are pleased that Biomet Biologics chose to expand our alliance to enable the development of this unique surgical product. This new agreement will allow Biomet to compete in the $450 million fibrin sealant market,” said Kevin Simpson, President & COO of ThermoGenesis.

“This new agreement will strengthen Biomet Biologics’ efforts to provide autologous surgical products that enhance outcomes and reduce patient risk as compared to animal derived and pooled human blood products,” said Joel Higgins, Vice President of Technical Affairs for Biomet Biologics.

Under the development phase of this agreement, Biomet Biologics will pay ThermoGenesis up to $1 million in milestone payments to develop the fibrinogen disposable and additional revenues upon the commencement of sales. Biomet Biologics will be responsible for regulatory submissions and any studies that may be necessary to gain approval with local regulatory authorities.

In a previous agreement, ThermoGenesis developed and now supplies Biomet Biologics with the Clotalyst(TM) System that prepares autologous thrombin from a small volume of the patient’s blood in approximately 30 minutes.
