Conditions

Hemophilia

Brief summary

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.

Interventions

DRUGAlbutrepenonacog Alfa 1 UNT [IDELVION]

Clinical data will be collected from patients who suffered from hemophilia B, and switch from other FIX products to Idelvion as prophylaxis, prevention of bleeding (e.g. surgery) or treatment of bleeding.
