[caption id="attachment_54704" align="alignleft" width="156"] Dr. Erdlenbruch[/caption] Response: At the World Federation of Hemophilia Virtual Summit 2020 (WFH 2020), results were presented from a real-world, post-marketing surveillance study aimed to evaluate the safety and effectiveness of RIXUBIS® in adult and pediatric patients with hemophilia B in South Korea, entitled “Safety and Effectiveness of Rixubis in Patients with Hemophilia B in South Korea: A Real-World, Prospective, Post-marketing Surveillance Study”. Data from the study demonstrate the safety and efficacy profile of RIXUBIS® for treatment of bleeds, perioperative/surgery, and prophylaxis in adult and pediatric patients with hemophilia B in the real-world setting in South Korea. The study showed that 86.6% (123/142) of hemostatic effectiveness assessments for RIXUBIS® were reported as good or excellent, and of the 11 adverse events reported, all were mild in severity, with 10 resolved/recovered events not related to RIXUBIS®, and one event (inhibitory antibody development) unconfirmed.¹ RIXUBIS® [Nonacog gamma, recombinant FIX concentrate] is a recombinant coagulation factor IX product, indicated for the control and prevention of bleeding episodes in patients with hemophilia B.
