Brief Summary
The purpose of this BAX 326 Continuation Study is to further investigate incremental recovery over time, the hemostatic efficacy, the safety, immunogenicity, and health-related quality of life (HR QoL) of BAX 326 in previously treated patients (PTPs) with severe and moderately severe hemophilia B who participated in BAX 326 pivotal study 250901 or BAX 326 pediatric study 251101.

Outcome Measures
Primary Outcomes (1)
Adverse Events Possibly or Probably Related to the Investigational Product
Possibly or probably related adverse events that occurred during or after first BAX326 infusion.
Assessed (based on patient diary) every 3 months until study completion (when BAX326 is licensed in the respective country or the participant has accumulated approximately 100 exposure days to BAX 326, whichever is last).
Secondary Outcomes (21)
Treatment of Bleeding Episodes: Number of Infusions Per Bleeding Episode Required Until Bleed Resolution
Throughout the study from screening to study completion (when BAX326 is licensed in the respective country or the participant has accumulated approximately 100 exposure days to BAX 326, whichever is last).
Treatment of Bleeding Episodes: Overall Hemostatic Efficacy Rating at Resolution of Bleed
Throughout the study from screening to study completion (when BAX326 is licensed in the respective country or the participant has accumulated approximately 100 exposure days to BAX 326, whichever is last).
Annualized Bleed Rate During Prophylaxis Treatment
For prophylactic treatment the period from first to last prophylactic infusion is considered.
Consumption of BAX 326: Number of Infusions Per Month and Per Year
Throughout the study from screening to study completion (when BAX326 is licensed in the respective country or the participant has accumulated approximately 100 exposure days to BAX 326, whichever is last).
Consumption of BAX 326: Weight Adjusted Consumption Per Month and Per Year
Throughout the study from screening to study completion (when BAX326 is licensed in the respective country or the participant has accumulated approximately 100 exposure days to BAX 326, whichever is last).
- +16 more secondary outcomes
Study Arms (1)
BAX 326
EXPERIMENTALInterventions
The treatment with BAX 326 will be at the discretion of the investigator and will consist of either twice weekly prophylactic treatment with 50 IU/kg, modified prophylaxis, or on-demand treatment.
