OMRIX Biopharmaceuticals Receives Food and Drug Administration (FDA) Approval for Thrombin Stand Alone, EVITHROM* Thrombin, Topical (Human), with General Hemostasis in Surgery Indication.

First and Only Bovine-Free Stand-Alone Topical Thrombin Approved by FDA 

NEW YORK -- OMRIX Biopharmaceuticals, Inc. ("OMRIX" or "The Company") (NASDAQ: OMRI), a commercial-stage biopharmaceutical company that develops and markets biosurgical and passive immunotherapy products, announced today that on August 27, 2007, the U.S. Food and Drug Administration, or FDA, approved its Biologics License Application, or BLA, to market its thrombin stand alone product, or Evithrom*, with a general hemostasis in surgery indication.

EVITHROM* was developed in collaboration with Johnson & Johnson Wound Management, a division of ETHICON, INC., a Johnson & Johnson Company. ETHICON will market EVITHROM* as both a stand-alone thrombin and in conjunction with an absorbable gelatin sponge such as SURGIFLO* Hemostatic Matrix with FlexTip. Johnson & Johnson Wound Management plans to make the product commercially available in the United States in Q4 2007.

"The offering of thrombin stand alone and thrombin in conjunction with an absorbable gelatin sponge such SURGIFLO are two additional building blocks to the one-stop-shop of biological hemostats Omrix and Ethicon are forming, stated Robert Taub, President and Chief Executive Officer of OMRIX Biopharmaceuticals, Inc. "This innovative concept of providing a one-stop-shop of biological hemostats will be getting closer to fruition once Evicel*, our fibrin sealant, will be approved with a general hemostasis indication. We anticipate this approval in January 2008 and the one-stop-shop concept will be further supplemented with the subsequent expected approval of our fibrin patch."

About EVITHROM* Thrombin Topical (Human)

EVITHROM* is a manufactured human plasma-derived alternative to the use of bovine protein-based thrombin, which is currently used to control bleeding in approximately one million surgical procedures each year in the United States. Exposure to bovine-derived thrombin has been shown to produce an immunogenic response in some patients. In patients who develop antibodies to bovine-derived thrombin there is an increased risk for complications including severe bleeding, thrombosis and anaphylactic shock. In addition, patients who develop antibodies to bovine-derived thrombin preparations are at a significantly higher risk of immunogenic response when re-exposed to these products.

EVITHROM* is shipped frozen and can be stored in the freezer for up to two years. EVITHROM* does not need to be reconstituted with a needle before use, as is the case with the current standard of care.

EVITHROM* is contraindicated in individuals known to have anaphylactic or severe systemic reaction to human blood products. As with all plasma-derived products, the risk of transmitting infectious agents cannot be completely eliminated. EVITHROM* should not be injected directly into the circulatory system and should not be used for the treatment of severe or brisk arterial bleeding.
