Sobi's partner Biogen Idec to present phase 3 data on prolonged half-life of Haemophilia candidates in young children at annual ASH meeting

Swedish Orphan Biovitrum AB's (publ ) (Sobi) partner Biogen Idec today announced
that new data from their haemophilia clinical development and research programs
will be presented at the 55th Annual Meeting of the American Society of
Hematology (ASH), taking place in New Orleans, December 7-10. Researchers will
discuss 10 abstracts covering the breadth of the company's comprehensive basic
and clinical research programs. This includes new interim data from Phase 3
studies in paediatric populations evaluating the company's investigational long-
lasting recombinant factor VIII Fc fusion protein candidate for haemophilia A
and factor IX Fc fusion protein candidate for haemophilia B.

The titles of the key presentations are as follows:

About the Fc Fusion Technology Platform
ELOCTATE and ALPROLIX were developed using Fc fusion technology, which takes
advantage of a naturally occurring pathway that delays the breakdown of IgG1
(protein commonly found in the body) by recycling it back into the bloodstream.
This technology is thought to be responsible for the prolonged time that
ALPROLIX and ELOCTATE circulate in the body. While Fc fusion is an established
technology that has been used for more than 15 years, Biogen Idec is the only
company to apply it in haemophilia.

About Haemophilia
Haemophilia is a rare, inherited disorder in which the ability of a person's
blood to clot is impaired. There are different types of haemophilia depending on
which clotting protein, or factor, is missing or reduced, including haemophilia
A (factor VIII deficiency) and haemophilia B (factor IX deficiency). Haemophilia
A occurs in about one in 5,000 male births annually. Haemophilia B is less
common, accounting for about one in 25,000 male births annually. Both forms of
haemophilia occur more rarely in females.

People with haemophilia can experience bleeding episodes that can cause pain,
irreversible joint damage and life-threatening haemorrhages. Prophylactic
infusions of factor VIII or IX can restore the coagulation process, as well as
reduce or prevent new bleeding episodes. The Medical and Scientific Advisory
Council of the National Haemophilia Foundation recommends prophylaxis as the
optimal therapy for people with severe haemophilia.

About the Biogen Idec and Sobi Collaboration
Biogen Idec and Swedish Orphan Biovitrum (Sobi) are partners in the development
and commercialization of ELOCTATE for haemophilia A and ALPROLIX for haemophilia
B. Biogen Idec leads development, has manufacturing rights, and has
commercialization rights in North America and all other regions excluding the
Sobi territory. Sobi has the right to opt in to assume final development and
commercialization in Europe (including Russia), the Middle East and Northern
Africa.
