Bioverativ Announces FDA Acceptance of Investigational New Drug Application for BIVV001 to Treat Hemophilia A

WALTHAM, Mass.--(BUSINESS WIRE)-- Bioverativ (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 that the U.S. Food and Drug Administration (FDA) has accepted the company’s Investigational New Drug (IND) application for BIVV001 (also known as rFVIIIFc-VWF-XTEN), a novel, investigational factor VIII therapy designed to potentially extend protection from bleeds with prophylaxis dosing of once weekly or longer for people with hemophilia A.

“People with hemophilia A continue to have a strong unmet need for therapies that can provide protection from bleeds and favorable long-term outcomes in terms of joint health and quality of life with once weekly dosing,” said Tim Harris, Ph.D., D.Sc., executive vice president of research and development at Bioverativ. “In 2014, we made significant progress toward this goal with the introduction of ELOCTATE®, the leading extended half-life therapy for hemophilia A. This IND acceptance expands on that legacy and reflects our continued commitment to advancing scientific innovation that can make a meaningful difference for people with hemophilia.”

BIVV001 builds on the company’s existing Fc fusion technology by adding a region of von Willebrand factor and XTEN polypeptides to potentially extend its time in circulation. It is the only investigational factor VIII therapy in development that is designed to overcome the von Willebrand factor ceiling, which is believed to impose a half-life limitation on current factor VIII therapies.

“BIVV001 is the first molecule of its kind to fuse four different proteins together to address the challenges of hemophilia A,” said Rob Peters, Ph.D., senior vice president of research at Bioverativ. “We are encouraged by our extensive preclinical data which show improved pharmacokinetics that are independent of von Willebrand factor, and look forward to commencing our Phase 1/2a clinical trial later this year.”

About Hemophilia A

Hemophilia A is a rare, chronic, genetic disorder in which the ability of a person’s blood to clot is impaired, due to missing or reduced levels of a protein known as factor VIII. People with hemophilia A experience bleeding episodes that may cause pain, irreversible joint damage and life-threatening hemorrhagesi. The World Federation of Hemophilia recommends prophylaxis as the optimal therapy as it can prevent bleedings and joint destruction and may improve quality of lifeii. An estimated 150,000 people worldwide are identified as living with hemophilia Aiii.

About ELOCTATE ® /Elocta ®

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 and 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/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.
