Bayer Receives FDA Approval for Jivi, New Hemophilia A Treatment

Bayer announced that the US Food and Drug Administration (FDA) has approved Jivi (BAY94-9027, antihemophilic factor [recombinant] PEGylated-aucl) for the routine prophylactic treatment of hemophilia A in previously treated adults and adolescents 12 years of age or older. The initial recommended prophylactic regimen for Jivi is twice weekly with the ability to dose every five days and further individually adjust to less or more frequent dosing based on bleeding episodes. The FDA also approved Jivi for on-demand treatment and the perioperative management of bleeding in the same population. This approval is based on results from the Phase 2/3 PROTECT VIII trial, which demonstrated bleed protection and safety of up to a median of 1.9 years (range of 0-2.6 years). Jivi is the third FDA-approved hemophilia A treatment in Bayer’s Hematology portfolio.

“As a physician who treats hemophilia A patients with a range of individualized needs, Jivi’s approved dosing allows me to adjust frequency based on their bleed episodes to maintain protection from bleeds, which is a serious concern among patients,” said Mark Reding, M.D., PROTECT VIII Lead Investigator and Associate Professor of Medicine at the University of Minnesota. “Jivi is a welcome option that addresses a growing patient need to integrate treatment with personal lifestyles.” Jivi works by replacing the reduced or missing factor VIII (FVIII) in adults and adolescents 12 years of age or older with hemophilia A. Through its site-specific PEGylation, Jivi has a half-life of 17.9 hours that delivers sustained levels in the blood. Jivi is an important new treatment option in recombinant FVIII (rFVIII) replacement therapy. Recombinant factor VIII is the standard of care for hemophilia A and has proven efficacy and safety established over decades of clinical trials and real-world experience.

Treatment with Jivi was well tolerated in the majority of adult and adolescent patients in clinical trials. The most frequently reported adverse reactions in previously treated patients 12 years of age or older were headache, cough, nausea, and fever. A FVIII inhibitor (1.7 BU/mL) was reported in one previously treated adult subject. Repeat testing did not confirm the presence of a FVIII inhibitor. The FDA approval of Jivi is supported by results of the pivotal Phase 2/3 PROTECT VIII trial comprised of prophylactic dosing, on-demand treatment, and perioperative management in adults and adolescents 12 years of age or older with severe hemophilia A. One hundred and twenty-six patients completed the main study.

“Today’s approval builds on our 25-year partnership with the hemophilia community and underscores our commitment to developing new therapies that help meet the needs of patients living with this life-long disease,” said Carsten Brunn, President of Bayer Pharmaceuticals, Americas Region. “Jivi’s proven efficacy with its unique dosing regimen is an important benefit to patients that we look forward to bringing to the global community, as we pursue additional regulatory approvals for Jivi in other regions around the world.” Bayer has also submitted marketing authorization applications for BAY94-9027 for the treatment of hemophilia A in the European Union and Japan. – Medical Buyer Bureau
