WALTHAM, Mass.--(BUSINESS WIRE)-- Bioverativ Inc. (NASDAQ: BIVV), a global biotechnology company focused on the discovery, development and commercialization of innovative therapies for hemophilia and other rare blood disorders, today announced clinical data from its leading extended half-life therapies ALPROLIX® Coagulation Factor IX (Recombinant), Fc Fusion Protein and ELOCTATE® Antihemophilic Factor (Recombinant), Fc Fusion Protein and preclinical data from its hemophilia pipeline, including BIVV001 for hemophilia A, will be presented at the International Society on Thrombosis and Haemostasis (ISTH) 2017 Congress, taking place in Berlin, Germany, from July 8-13, 2017.
“We are excited to attend our first ISTH Congress as Bioverativ, and the breadth of data we will be presenting underscores our commitment to scientific innovation for people with hemophilia and demonstrates our growing leadership in this field,” said Tim Harris, Ph.D., D.Sc., Executive Vice President of Research and Development at Bioverativ. “Our data at ISTH will also highlight our work to develop a pipeline of novel therapies for hemophilia, including several presentations on BIVV001, our potential next-generation factor VIII therapy designed to extend protection from bleeds with prophylaxis dosing of once weekly or longer.”
Bioverativ will present a total of 19 hemophilia-related posters, including nine joint presentations with Swedish Orphan Biovitrum AB (publ) (Sobi™) during the Congress. Research supporting Bioverativ’s pipeline programs will be presented in multiple poster and oral presentations including data on the investigational compound BIVV001 (rFVIIIFc-VWF-XTEN), which is the first molecule of its kind to fuse four different proteins for the treatment of hemophilia A. The U.S. Food and Drug Administration recently accepted the Investigational New Drug application for BIVV001 and Bioverativ is on track to initiate a Phase 1/2a trial in the second half of the year.
In addition, new findings from the ASPIRE and B-YOND extension studies will support ELOCTATE’s and ALPROLIX’s potential to deliver improved long-term joint-health and quality-of-life outcomes for people with hemophilia A and B, respectively. A late-breaking poster presentation on the use of ELOCTATE for immune tolerance induction will also be presented.
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, and real-world experience with initiating and continuing treatment with ELOCTATE and ALPROLIX and their impact on long-term treatment goals.
Highlights of Bioverativ and Sobi’s joint presentations on ALPROLIX and ELOCTATE at ISTH can be found here.

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 hemophilia 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 hemophilia. 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 hemophilia A. Inhibitor development has been observed with 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 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.
