Outcome Measures

Primary Outcomes (6)

  • Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability or incapacity; cancer; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to last visit (up to 8.7 years) that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious.

    Baseline until last visit (up to 8.7 years)

  • Number of Participants With Treatment-Related Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; cancer; congenital anomaly. AEs included both serious and non-serious. Relatedness to BeneFIX was assessed by the investigator.

    Baseline until last visit (up to 8.7 years)

  • Number of Participants With Factor IX (FIX) Inhibitor Development as Measured by the Nijmegen-Modified Bethesda Assay

    FIX inhibitor development was defined as measured inhibitor titer of greater than (\>) 0.6 Bethesda Units (BU) using the Nijmegen-modified Bethesda assay.

    Baseline until last visit (up to 8.7 years)

  • Number of Participants With Adverse Events (AEs) of Special Interest

    An AE was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. Adverse Events of special interest included allergic reactions, less than expected therapeutic effect (LETE) of drug, lack of efficacy/low recovery, erythrocyte agglutination in tube or syringe red blood cell (RBC) agglutination phenomena and thrombogenicity.

    Baseline until last visit (up to 8.7 years)

  • Investigator Assessment of Treatment Tolerability of Participants

    Investigator assessed the tolerability of participants and categorized as very good, good, moderate and poor.

    End of study visit (any time up to 8.7 years)

  • Participant Assessment of Treatment Tolerability

    Participants evaluated their treatment (BeneFIX) tolerability and rated it in 4 categories as very good, good, moderate and poor.

    End of study visit (any time up to 8.7 years)

Secondary Outcomes (8)

  • Mean Total Number of Bleeding Episodes in Participants

    Baseline until last visit (up to 8.7 years)

  • Mean Total Number of Bleeding Episodes Per Year in Participants

    Baseline until last visit (up to 8.7 years)

  • Number of Participants With Change From Baseline Status in Number of Days Missed From School or Work

    Baseline, up to 8.7 years

  • Investigator Assessment of Treatment Efficacy of Participants

    End of study visit (any time up to 8.7 years)

  • Investigator Assessment of Treatment Handling of Participants

    End of study visit (any time up to 8.7 years)

  • +3 more secondary outcomes
