European Commission (EC) Approves Transfer Of Marketing Authorisation For Alprolix Sobi

STOCKHOLM--(BUSINESS WIRE)--Swedish Orphan Biovitrum AB (STO:SOBI)

Swedish Orphan Biovitrum AB (publ) (http://www.sobi.com/) (Sobi™) today announces that the European Commission (EC) has approved the transfer of the marketing authorisation for Alprolix® (eftrenonacog alfa), a recombinant clotting factor therapy developed for the treatment of haemophilia B, from Biogen[i] to Sobi, making Sobi the marketing authorisation holder (MAH) in the EU. The EC has also approved the transfer of the orphan designation to Sobi.

As MAH, Sobi will assume full regulatory responsibility for Alprolix in the EU.

The EC approval of Alprolix on 12 May 2016 was based on results from two global phase 3 clinical trials that demonstrated the efficacy, safety and pharmacokinetics of Alprolix for the treatment of haemophilia B: the pivotal B-LONG study for previously treated adults and adolescents, and the Kids B-LONG study for previously treated children under age 12.

About haemophilia B

Haemophilia is a rare, genetic disorder in which the ability of a person’s blood to clot is impaired. Haemophilia B occurs in about one in 25,000 male births annually, and more rarely in females. Worldwide, it is estimated that between 60,000 and 80,000[i] people are living with haemophilia B.

People with haemophilia B experience bleeding episodes that can cause pain, irreversible joint damage and life-threatening haemorrhages. Prophylactic infusions of factor IX can temporarily replace the clotting factor needed to control bleeding and prevent new bleeding episodes.[ii] The World Federation of Hemophilia recommends prophylaxis as the optimal therapy as it can prevent bleedings and joint destruction.[iii]

About Alprolix®

Alprolix® (eftrenonacog alfa) is a recombinant clotting factor therapy developed for haemophilia B by fusing factor IX to the Fc portion of immunoglobulin G subclass 1, or IgG1 (a protein commonly found in the body). This enables Alprolix to use a naturally occurring pathway to prolong the time the therapy remains in the body. While Fc fusion technology has been used for more than 15 years, Sobi and Biogen are the first companies to utilise it in the treatment of haemophilia.

Alprolix is currently approved for the treatment of haemophilia B in the European Union, Iceland, Liechtenstein and Norway, as well as the United States, Canada, Japan, Australia, New Zealand and other countries. As with any factor replacement therapy, allergic-type hypersensitivity reactions and development of inhibitors may occur following administration of Alprolix.
