The Effectiveness of Recombinant Coagulation Factor IX With Recombinant Albumin (rIX-FP) in Severe Hemophilia B Patients

October 28, 2020 updated by: National Taiwan University Hospital

The Effectiveness of Recombinant Fusion Protein Linking Coagulation Factor IX With Recombinant Albumin (rIX-FP) in Severe Hemophilia B Patients Switching From Previous Factor IX Treatment

The pivotal clinical data support prolonged dosing intervals of up to 14 days for routine prophylaxis in hemophilia B patients. The majority of adult and pediatric patients using Idelvion for routine prophylaxis had a median annualized spontaneous bleeding rate (AsBR) of 0.00. The majority (99%) of bleeding episodes were managed successfully with one or two infusions, and 94% of bleeds were controlled with only one infusion regardless of the cause or location.

The rationale for this study is to collect the effectiveness and safety data of severe hemophilia B patients treated with Idelvion following institutional standard of care. It is the aim of this study to extend the results of the clinical trial program to a broader hemophilia B population, and to compare with current alternative factor IX treatments in Taiwan.
