2/7/07 – Stonefly Wins Assignment with ZymoGenetics' RECOTHROM™
Agency Will Lead Professional Advertising and Promotion

Columbus, Ohio – February 7, 2007 – Stonefly Communications Group, an inVentiv Health company (NASDAQ:VTIV) and a purpose-driven, patient focused healthcare advertising agency, announces it has been selected by ZymoGenetics to lead the marketing and promotion of RECOTHROM. RECOTHROM is the first and only recombinant, plasma-free thrombin approved for surgical use.

Recently approved by the FDA, 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. With thrombin being used in more than one 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.

"We are thrilled to be working with such a great team at ZymoGenetics," said John Racik, president and CEO of Stonefly Communications Group.  "With the recent FDA approval of RECOTHROM, many patients and surgeons will be able to benefit from this plasma-free alternative. We are very pleased to be putting our team's skill and experience to work for such an important new product."

"We are excited to work with Stonefly. Their unique marketing experience is a great complement to our team's capabilities,” said Cheryl Birch Hostinak, marketing director at ZymoGenetics.  "As the first and only recombinant thrombin for surgical hemostasis, RECOTHROM shows great promise. We look forward to partnering with Stonefly to drive product growth to the next level.”

ZymoGenetics creates novel protein drugs with the potential to significantly help patients fight their diseases. The company has a diverse pipeline of products moving into and through clinical development. These candidates span a wide array of clinical opportunities that include bleeding, autoimmune and viral diseases and cancer. For further information, visit www.zymogenetics.com.
