WALTHAM, Mass. & STOCKHOLM--(BUSINESS WIRE)-- Bioverativ Inc. (NASDAQ: BIVV) and Swedish Orphan Biovitrum AB (publ) (Sobi™) (STO: SOBI) today announced that new data from their extended half-life therapies, ALPROLIX® Coagulation Factor IX (Recombinant), Fc Fusion Protein and ELOCTATE® Antihemophilic Factor (Recombinant), Fc Fusion Protein, marketed as Elocta® in Europe and the Middle East, will be presented at the International Society on Thrombosis and Haemostasis (ISTH) 2017 Congress, taking place in Berlin, Germany, from July 8-13, 2017.
Researchers and investigators will present updated analyses of long-term follow-up data from the ASPIRE and B-YOND extension studies in adults, adolescents and children, further supporting the existing safety and efficacy of ELOCTATE and ALPROLIX. Data from the first and only longitudinal study of joint health in patients treated prophylactically with extended half-life therapies will also be presented. These data and the additional findings reported on joint health and long-term quality-of-life outcomes reflect the companies’ commitment to addressing areas of unmet need in hemophilia.
“Debilitating joint disease is a common and challenging complication for people with hemophilia,” said Maha Radhakrishnan, MD, Senior Vice President of Medical at Bioverativ. “New data supporting ELOCTATE’s and ALPROLIX’s impact on long-term joint health when used prophylactically will be presented at ISTH, and reflect our continued focus on improving the care and clinical outcomes for people living with hemophilia.”
Most bleeding events for people with severe hemophilia A and B occur in joints, with joint damage being the most common complication of the condition.1 Data presented at ISTH will demonstrate improvements in modified hemophilia joint health scores, low target joint annualized bleed rates (ABRs) and target joint resolution for people receiving prophylactic treatment with ELOCTATE and ALPROLIX. The long-term safety and efficacy of these products will also be presented at the Congress.
“New data will reinforce that ELOCTATE and ALPROLIX treatment can maintain low ABRs, therefore helping improve the long-term quality-of-life for people with hemophilia A and B,” said Krassimir Mitchev, MD, PhD, Vice President and Medical Therapeutic Area Head of Haemophilia at Sobi. “Based on hemophilia-related quality-of-life measures, findings will show that improvements were seen in patients utilizing these therapies over several years, with the most pronounced improvement in areas including physical health and sports and leisure.”
The development of inhibitors to factor replacement therapy is one of the most serious complications for people with hemophilia, and immune tolerance induction (ITI) treatment can represent a significant burden for patients and their quality of life. A retrospective chart analysis (United States and Canada) on ELOCTATE used for ITI in severe hemophilia A patients with inhibitors will also be discussed in a late-breaking poster presentation. ELOCTATE is not currently approved for immune tolerance induction in the United States or Canada.
In addition to the data being presented at the Congress, Bioverativ and Sobi will co-host a company-sponsored scientific symposium, “Fc Extended Half-Life Recombinant Factor Concentrates: Recent Updates on Haemophilia Management and Treatment Goals,” on July 10 at 13:15 –14:30 CEST. Supported by global patient case reports, the session will focus on features of Fc fusion factors, evolving technologies and methodologies in hemophilia management, plus real-world experience with initiating and continuing treatment with ELOCTATE and ALPROLIX and their impact on long-term treatment goals.
Presentation highlights include:

About Hemophilia A and B
Hemophilia is a rare, genetic disorder in which the ability of a person's blood to clot is impaired. Hemophilia A occurs in about one in 5,000 male births annually, and more rarely in females. Hemophilia 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 hemophilia A and B worldwide.1
People with hemophilia A or B experience bleeding episodes that can cause pain, irreversible joint damage and life-threatening hemorrhages. Prophylactic infusions of factor VIII or IX can temporarily replace the clotting factors that are needed to control bleeding and prevent new bleeding episodes.2 The World Federation of Hemophilia recommends prophylaxis as the optimal therapy as it can prevent bleedings and joint destruction.3
ELOCTATE® Antihemophilic Factor (Recombinant), Fc Fusion Protein is a recombinant clotting factor therapy developed for haemophilia A using Fc fusion technology to prolong circulation in the body. 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 ELOCTATE 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, Bioverativ and Swedish Orphan Biovitrum AB (publ) (Sobi) have optimized the technology and are the first companies to utilize it in the treatment of haemophilia. ELOCTATE is manufactured using a human cell line in an environment free of animal and human additives.
ELOCTATE is approved and marketed by Bioverativ in the United States, Japan and Canada. It is also approved in Australia, New Zealand, Brazil and other countries, and Bioverativ has marketing rights in these regions. It is also approved as Elocta® in the European Union, Switzerland, Iceland, Liechtenstein, Norway and other countries where it is marketed by Sobi.
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 ELOCTATE/Elocta, 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 is not included in the EU Product Information for Elocta.
ALPROLIX® Coagulation Factor IX (Recombinant), Fc Fusion Protein is a recombinant clotting factor therapy developed for hemophilia 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 optimized the technology and are the first companies to utilize it in the treatment of hemophilia. ALPROLIX is manufactured using a human cell line in an environment free of animal and human additives.
ALPROLIX is approved and marketed by Bioverativ for the treatment of hemophilia B in the United States, Japan and Canada. It is also approved in Australia, New Zealand, Brazil and other countries, and Bioverativ has marketing rights in these regions. It is also authorized in the European Union, Iceland, Liechtenstein, Norway and Switzerland, where it is marketed by Sobi.
Allergic-type hypersensitivity reactions and development of inhibitors have been observed with ALPROLIX in the treatment of hemophilia 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.
