What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BeneFIXDrug

    Patients will be treated in accordance with the requirements of the labeling of BeneFIX in Germany. The dosage and duration of therapy is to be determined by the physician to meet the patients' individual needs for treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Baseline until last visit (up to 8.7 years)

  2. 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.

    Measured: Baseline until last visit (up to 8.7 years)

  3. 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.

    Measured: Baseline until last visit (up to 8.7 years)

  4. 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.

    Measured: Baseline until last visit (up to 8.7 years)

  5. Investigator Assessment of Treatment Tolerability of Participants

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

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

  6. Participant Assessment of Treatment Tolerability

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

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

Secondary outcomes (8)
  1. Mean Total Number of Bleeding Episodes in Participants

    Participants documented all bleeding episodes in a diary during the study.

    Measured: Baseline until last visit (up to 8.7 years)

  2. Mean Total Number of Bleeding Episodes Per Year in Participants

    Participants documented all bleeding episodes in a diary during the study. Mean total number of bleeding episodes per year was calculated by mean total number of bleeding episodes divided by duration of observation period (in years) for bleeding documentation.

    Measured: Baseline until last visit (up to 8.7 years)

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

    Change from baseline status in days missed from school or work was categorized in 3 categories: Improvement, unchanged and worsening. Improvement was defined as a decrease in number of days missed by participants from school/work as compared to baseline; worsening was defined as an increase in number of days missed by participants from school/work as compared to baseline; unchanged was defined as no change in number of days missed by participants from school/work as compared to baseline. In this outcome measure, number of participants with change from baseline status (as improved, worsen, unchanged) in days missed from school/work were reported.

    Measured: Baseline, up to 8.7 years

  4. Investigator Assessment of Treatment Efficacy of Participants

    Investigator evaluated the efficacy of BeneFIX in participants and rated it in 4 categories as very good, good, moderate and poor.

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

  5. Investigator Assessment of Treatment Handling of Participants

    Investigator evaluated the handling (administration) of BeneFIX by participants and rated it in 4 categories as very good, good, moderate and poor.

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

  6. Assessment of Treatment Efficacy by the Participants

    Participants evaluated the efficacy of BeneFIX and rated it in 4 categories as very good, good, moderate and poor.

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

  7. Assessment of Treatment Handling by the Participants

    Participants evaluated the handling (administration) of BeneFIX and rated it in 4 categories as very good, good, moderate and poor.

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

  8. Investigator Assessment of Treatment Satisfaction of Participants

    Investigator evaluated the participant's satisfaction of treatment with BeneFIX and rated it in 4 categories as very satisfied, satisfied, unsatisfied and very unsatisfied.

    Measured: Baseline up to 8.7 years

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Baseline until last visit (up to 8.7 years)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
