Surgeons to Be Offered Broader Line of Product Presentations

SEATTLE--(HSMN NewsFeed)--ZymoGenetics, Inc. (NASDAQ:ZGEN ) announced today that the United States Food and Drug Administration (FDA) has approved a Prior Approval Supplement application for a 20,000 international unit (IU) vial of RECOTHROMTM Thrombin, topical (Recombinant) and also approved co-packaging of the 20,000-IU vial with the ZymoGenetics Spray Applicator Kit.

“RECOTHROM, the first and only recombinant thrombin, is now available in both 5,000 and 20,000-IU vial sizes,” said Bruce L.A. Carter, Chief Executive Officer of ZymoGenetics. “Within two weeks, we’ll be ready to ship the 20,000-IU vials, as well as spray kits co-packaged with the larger vial. This product introduction will provide our customers with flexibility to meet their needs while enhancing our ability to convert hospital thrombin usage to RECOTHROM. Additionally, we believe that our spray kit has design and convenience advantages, based on market research conducted with surgeons.”

About RECOTHROM™ Thrombin, topical (Recombinant)

RECOTHROM is a recombinant form of human thrombin that is structurally and functionally similar to human thrombin. It is not derived from animal or human blood. With thrombin being used in more than 1 million surgeries each year in the United States, RECOTHROM gives surgeons the opportunity to provide their patients with a plasma-free thrombin alternative for surgical hemostasis. The production of recombinant proteins is not dependent on the availability of blood from animals or human donors and can be scaled up to meet market demand.

RECOTHROM is indicated as an aid to hemostasis whenever oozing blood and minor bleeding from capillaries and small venules is accessible and control of bleeding by standard surgical techniques is ineffective or impractical. RECOTHROM may be used in conjunction with an absorbable gelatin sponge, USP.

IMPORTANT SAFETY INFORMATION

RECOTHROM is for topical use only and should not be injected directly into the circulatory system. There is a potential risk of thrombosis if the product is absorbed systemically. RECOTHROM should not be used for the treatment of massive or brisk arterial bleeding or in patients with known hypersensitivity to RECOTHROM, any components of RECOTHROM or hamster proteins.

No specific adverse events have been established as adverse reactions causally related to RECOTHROM administration. In a clinical study comparing RECOTHROM to bovine thrombin, adverse events were reported with similar frequency in both treatment groups. The most common event was incision site complication. Limited data (n = 6) are available on repeat exposure to RECOTHROM.
