Swedish Orphan Biovitrum to Increase the Availability of Willfact(R) to von Willebrand Patients as LFB Biomedicaments Has Received Additional European Regulatory Approvals

STOCKHOLM, SWEDEN--(Marketwire - December 20, 2010) -

Swedish Orphan Biovitrum (STO: SOBI) today announced that LFB BIOMEDICAMENTS (LFB) has received a positive review of Willfact® under a Mutual Recognition Procedure (MRP), by the German regulatory authority (the Paul-Ehrlich-Institute) representing the other European authorities involved in the procedure.

Following final local regulatory approvals and pricing and reimbursement processes, Swedish Orphan Biovitrum (Sobi) will launch Willfact in Sweden, Norway, Denmark, Estonia, Latvia, Lithuania, Czech Republic, Slovakia, Slovenia (Willefact®), and Hungary. Sobi expects to begin launching Willfact in some of these countries as early as during the second quarter of 2011.

"The positive MRP review is a big step towards making Willfact available to von Willebrand disease patients in additional countries in Europe and thereby an opportunity to improve the life of these patients. We look forward to a fruitful and continued partnership with LFB BIOMEDICAMENTS, and we see Willfact as an important addition to our emerging Hemophilia franchise," said Kennet Rooth, CEO of Sobi.

About Willfact® and the agreement with LFB BIOMEDICAMENTS Willfact is a very high purity plasma derived human von Willebrand factor (vWF) concentrate used to stop and prevent bleeding in severe von Willebrand disease (vWD) patients. It is produced by LFB BIOMEDICAMENTS and is the only vWF concentrate almost free from Factor VIII, and thereby specifically designed for the treatment of vWD patients.

Willfact was approved in Germany in May 2009, the largest pharmaceutical market in Europe, by the German authorities (the Paul-Ehrlich-Institute) for the prevention and treatment of hemorrhages or surgical bleeding in vWD when Desmopressin (DDAVP) treatment alone is ineffective or contraindicated. Willfact is distributed in Germany by Swedish Orphan International GmbH, a subsidiary of Sobi. Willfact was launched in Germany in April 2010.

Sobi will, under the agreement with LFB BIOMEDICAMENTS, distribute Willfact in Germany, Sweden, Norway, Denmark, Estonia, Latvia, Lithuania, Slovenia, Czech Republic, Slovakia and Hungary.

About von Willebrand Disease

Von Willebrand Disease (vWD) is characterized by a deficiency in the protein von Willebrand Factor (vWF) that plays a role in primary hemostasis and stabilizes Factor VIII, an essential blood coagulation factor. This disease requires extensive diagnostic measures and therapeutic options are available which need to be adapted to the individual needs of the patients. About one percent of the population is affected by vWD and equally effects men and women. vWD is thereby the most frequent inherited bleeding disorder. However, only 52.000 patients are diagnosed globally. According to the Marketing Research Bureau the vWF market 2008 was 325 MUSD.

vWD is divided in three disease types: Type 1 is characterized by mildly or moderately reduced vWF levels (60-80% of patients), whereas in Type 3 vWD patients vWF levels are reduced more dramatically (less than 3% of patients). Type 2 vWD (20-40% of patients) is characterized by qualitative deficiencies in the vWF protein, thereby losing important protein functions. For Type 1 - and many type 2 patients, desmopressin (DDAVP) is the current treatment of choice. For some Type 1, many Type 2 - and all Type 3 vWD-patients, however, DDAVP treatment alone is not sufficient or is contraindicated.

All three types of vWD may benefit from a substitution with a plasma- derived vWF. In Germany, treatment options have been limited to blood plasma concentrates containing a combination of vWF and Factor VIII. However, in vWD patients the endogenous Factor VIII synthesis is intact and the deficiency of Factor VIII is a secondary effect due to the lack or absence of vWF. Therefore a substitution of Factor VIII is only needed in emergency situations with significant blood loss. High levels of factor VIII may unnecessarily increase the risk for thrombosis and thereby stroke.
