The nine posters include data on the long-term safety and efficacy of the companies' extended half-life therapies, Elocta® (efmoroctocog alfa), marketed as ELOCTATE® [Antihemophilic Factor (Recombinant), Fc Fusion Protein] in the United States, Japan and Canada, and Alprolix® (eftrenonacog alfa), in people of all ages with haemophilia A and B, respectively, providing an updated analysis of long-term data from the registration studies ASPIRE and B-YOND.
"Sobi and Bioverativ are committed to supporting the haemophilia community to better understand the potential of extended half-life factor treatments," says Krassimir Mitchev, MD, PhD, vice president and medical therapeutic area head of Haemophilia at Sobi. "These data present how to individualise dosing and consumption in order to gain a comprehensive protection beyond prevention of bleeds."
"These data provide additional insights for physicians and people living with haemophilia, and reinforce the well-characterised safety and efficacy profile for Elocta/ELOCTATE and Alprolix. These are the only haemophilia therapies utilizing Fc fusion technology, which uses the body's natural pathway to prolong the time the therapy remains in the body," said Maha Radhakrishnan, MD, senior vice president of medical at Bioverativ.

About haemophilia A and B
Haemophilia is a rare, genetic disorder in which the ability of a person's blood to clot is impaired. Haemophilia A occurs in about one in 5,000 male births annually, and more rarely in females. Haemophilia B occurs in about one in 25,000 male births annually, and more rarely in females. The World Federation of Hemophilia estimates that approximately 180,000 people are currently diagnosed with haemophilia A and B world-wide[vii].
People with haemophilia A or B experience bleeding episodes that can cause pain, irreversible joint damage and life-threatening haemorrhages. Prophylactic injections of factor VIII or IX can temporarily replace the clotting factors that are needed to control bleeding and prevent new bleeding episodes[viii]. The World Federation of Hemophilia recommends prophylaxis as the optimal therapy as it can prevent bleedings and joint destruction[ix].
Elocta® (efmoroctocog alfa), is a recombinant clotting factor therapy developed for haemophilia A with prolonged circulation in the body using Fc fusion technology. It is engineered by fusing factor VIII to the Fc portion of immunoglobulin G subclass 1, or IgG1 (a protein commonly found in the body), enabling Elocta to use a naturally occurring pathway to extend the time the therapy remains in the body. While Fc fusion technology has been used for more than 15 years, Sobi and Bioverativ have optimised the technology and are the first companies to utilise it in the treatment of haemophilia. Elocta is manufactured using a human cell line in an environment free of animal and human additives.
Elocta is approved for the treatment of haemophilia A in the European Union, Iceland, Liechtenstein, Norway, Switzerland, and Kuwait, and marketed by Sobi. In the United States, Japan, Canada, Australia, New Zealand, Brazil, and other countries, it is approved as ELOCTATE® [Antihemophilic Factor (Recombinant), Fc Fusion Protein], and Bioverativ has marketing rights in these regions.
As with any factor replacement therapy, allergic-type hypersensitivity reactions and development of inhibitors may occur in the treatment of haemophilia A. Inhibitor development has been observed with Elocta/ELOCTATE, including in previously untreated patients. For more information, please see the full U.S. prescribing information for ELOCTATE. Note that the indication for previously untreated patients in not included in the EU Product Information for Elocta.
Alprolix® (eftrenonacog alfa) [Coagulation Factor IX (Recombinant), Fc Fusion Protein], is a recombinant clotting factor therapy developed for haemophilia B using Fc fusion technology to prolong circulation in the body. It is engineered by fusing factor IX to the Fc portion of immunoglobulin G subclass 1, or IgG1 (a protein commonly found in the body), enabling Alprolix to use a naturally occurring pathway to extend the time the therapy remains in the body (half-life). While Fc fusion technology has been used for more than 15 years, Bioverativ and Sobi have optimised the technology and are the first companies to utilise it in the treatment of haemophilia. Alprolix is manufactured using a human cell line in an environment free of animal and human additives.
Alprolix is approved for the treatment of haemophilia B the European Union, Iceland, Liechtenstein, Norway and Switzerland, and marketed by Sobi. It is also approved in the United States, Canada, Japan, Australia, New Zealand, Brazil and other countries, and Bioverativ has marketing rights in these regions.
Allergic-type hypersensitivity reactions and development of inhibitors have been observed with Alprolix in the treatment of haemophilia B, including in previously untreated patients. For more information, please see the full U.S. prescribing information for Alprolix. Note that the indication for previously untreated patients is not included in the EU Product Information.
