Maxygen Achieves Milestone in Alliance with Roche for Factor VIIa Therapeutics

REDWOOD CITY, Calif., May 9 (HSMN NewsFeed) -- Maxygen, Inc. (Nasdaq: MAXY ) today announced that it has achieved a $5 million preclinical milestone in its alliance with Roche to co-develop next-generation factor VIIa therapeutics. Maxygen has achieved the milestone for development of a manufacturing process for its factor VIIa product candidates.

In December 2005, Maxygen and Roche established an agreement to co-develop and commercialize next-generation factor VIIa products for multiple indications of severe bleeding, including trauma and intracerebral hemorrhage (ICH). Under the terms of the agreement, Roche and Maxygen agreed to share worldwide research and development costs for the creation of next-generation factor VIIa product candidates. Maxygen is leading early stage clinical development, and Roche will lead late stage clinical development. Roche will have exclusive worldwide rights to commercialize the next-generation recombinant factor VIIa products for acute indications. Including an upfront fee, total event payments to Maxygen could total $95 million. In addition, Maxygen is also eligible to receive royalties on product sales. Maxygen has retained all rights for development and commercialization of its next-generation recombinant factor VIIa product candidates for hemophilia.

"This milestone represents significant progress in our next-generation factor VIIa program," said Russell Howard, CEO of Maxygen. "We view Roche as a leader in the development, manufacture and commercialization of biologics and we are pleased that they have accepted the manufacturing process developed by our project team. We are very excited about this program and the potential to develop improved factor VIIa products specifically tailored for acute bleeding indications."

Maxygen also announced that it has entered into an agreement with Rentschler Biotechnologie GmbH for the manufacture of the clinical supply of its next-generation factor VIIa protein therapeutics and has initiated technology transfer to Rentschler.

About Recombinant Factor VII

Factor VII is a natural protein with a pivotal role in blood coagulation and clotting. Currently, recombinant factor VIIa is approved in the United States and Europe only for the treatment of hemophilia. The market for the use of all factor VIIa products for the treatment of new indications, such as severe bleeding in trauma and intracerebral hemorrhage is estimated to exceed $2 billion by 2012.

About Trauma

It is estimated that there are over 160,000 deaths in the United States each year that are a direct result of trauma injuries. The direct and indirect healthcare costs associated with trauma injuries are estimated to be approximately $260 billion per year. Uncontrolled bleeding is believed to account for approximately half of all trauma related deaths that occur within the first 48 hours after injury. There is currently no effective medical therapy for uncontrolled bleeding other than physical interventions, such as surgery or blood transfusions.

About ICH

Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, occurs when a blood vessel within the brain bursts, allowing blood to leak inside the brain. The sudden increase in pressure within the brain can cause damage to the brain cells. If the amount of blood increases rapidly, the sudden buildup in pressure can lead to severe neurological impairment, coma or death. The most common cause of intracerebral hemorrhage is high blood pressure (hypertension). Hemorrhagic strokes make up about 12% of all strokes.
