FDA Approves Baxter's Obizur for Acquired Hemophilia A

FDA has approved Baxter International's Obizur [Antihemophilic Factor (Recombinant), Porcine Sequence] for the treatment of bleeding episodes in adults with acquired hemophilia A (AHA), a rare and potentially life-threatening acute bleeding disorder. Obizur was granted orphan-drug status by the FDA and its review was prioritised based on AHA's classification as a rare disease and the potential for the treatment to address an important unmet medical need.

 

Obizur is the first recombinant porcine FVIII treatment approved for AHA that allows physicians to manage the treatment's efficacy and safety by measuring factor VIII activity levels in addition to clinical assessments. Obizur replaces the inhibited human factor VIII with a recombinant porcine sequence factor VIII based on the rationale that it is less susceptible to inactivation by circulating human factor VIII antibodies.

 

"The approval of Obizur is welcome news for the hemophilia community based on the data from the first clinical trial designed specifically for acquired hemophilia A, which found that all patients responded to treatment within 24 hours," said Rebecca Kruse-Jarres, Director of the Hemophilia Care Program at Puget Sound Blood Center in Seattle and the clinical trial's principal investigator. "Importantly, this new option to treat bleeding episodes will enable us to measure factor VIII levels, thus giving us an objective marker of hemostasis that can guide dosing and prevent overdosing."
