Временное ограничение
Number of Participants With Any Positive Inhibitor Development
Временное ограничение: Approximately 5 years
An inhibitor test result greater than or equal to (>=)0.6 Bethesda units per milliliter (BU/mL), confirmed on 2 separate samples drawn 2 to 4 weeks apart, was considered positive. Both tests were to be performed by the central laboratory using the Nijmegen-modified Bethesda Assay. Data was summarized by treatment regimen for participants from Study 998HB102 and by age cohort (<6 years and 6 to <12 years old) and treatment regimen for participants from Study 9HB02PED per planned analysis. Participants were included in summary of more than 1 treatment regimen if their regimen changed during study.

Вторичные показатели результатов

Мера Описание
Временное ограничение
Annualized Bleeding Rate (ABR)
Временное ограничение: Approximately 5 years
ABR is annualized number of bleeding episodes per participant per year. Bleeding episodes were classified as spontaneous if participant records bleeding event when there is no known contributing factor such as definite trauma/antecedent strenuous activity and classified as traumatic if participant records bleeding event when there is known reason for bleed. ABR=(Number of bleeding episodes during efficacy period/number of days during efficacy period)*365.25. Efficacy period reflects sum of all intervals of time during which participants were treated with rFIXFc per treatment regimen excluding major and minor surgical/rehabilitation periods and large injection intervals. ABR was summarized by treatment regimen for participants from study 998HB102 and by age cohort (<6 years and 6 to <12 years old) and treatment regimen for participants from study 9HB02PED per planned analysis. Participants were included in summary of more than 1 treatment regimen if their regimen changed during study.
Approximately 5 years
Annualized Spontaneous Joint Bleeding Episodes
Временное ограничение: Approximately 5 years
Bleeding episodes were classified as spontaneous if participant records a bleeding event when there is no known contributing factor such as definite trauma/antecedent strenuous activity. In addition, location of bleed (joint, internal, skin/mucosa or muscle) were also collected. Annualized spontaneous joint bleeding episodes=(Number of spontaneous joint bleeding episodes during efficacy period/number of days during efficacy period)*365.25. Efficacy period reflects sum of all intervals of time during which participants were treated with rFIXFc per treatment regimen excluding major and minor surgical/rehabilitation periods and large injection intervals. Bleeding episodes were summarized by treatment regimen for participants from study 998HB102 and by age cohort (<6 years and 6 to <12 years old) and treatment regimen for participants from study 9HB02PED as per planned analysis. Participants were included in summary of more than 1 treatment regimen if their regimen changed during study.
Approximately 5 years
Total Number of Exposure Days (EDs)
Временное ограничение: Approximately 5 years
An exposure day is a 24-hour period in which one or more rFIXFc injections are given. The total number of days of exposure to rFIXFc were summarized by treatment regimen for participants from study 998HB102 and by age cohort (<6 years and 6 to <12 years old) and treatment regimen for participants from study 9HB02PED as per planned analysis. Participants were included in summary of more than 1 treatment regimen if their regimen changed during study.
Approximately 5 years
Annualized rFIXFc Consumption (International Units Per Kilogram [IU/kg])
Временное ограничение: Approximately 5 years
Annualized consumption = (total international unit per kilogram [IU/kg] of study treatment received during the efficacy period / total number of days during the efficacy period) multiplied by 365.25. Efficacy period reflects sum of all intervals of time during which participants were treated with rFIXFc per treatment regimen excluding major and minor surgical/rehabilitation periods and large injection intervals. Annualized consumption was summarized by treatment regimen for participants from study 998HB102 and by age cohort (<6 years and 6 to <12 years old) and treatment regimen for participants from study 9HB02PED as per planned analysis. Participants were included in summary of more than 1 treatment regimen if their regimen changed during study.
Approximately 5 years
Physicians' Global Assessment of Participant's Response to rFIXFc Regimen Using a 4-Point Scale
Временное ограничение: Approximately 5 years
Participants were assessed for response to their rFIXFc regimen using following 4-point scale: 1=Excellent: bleeding episodes responded to less than or equal to (<=)usual number of injections or dose of rFIXFc or rate of breakthrough bleeding during prophylaxis was <= that usually observed; 2=Effective: most bleeding episodes responded to same number of injections and dose, but some required more injections or higher doses, or there was minor increase in rate of breakthrough; 3=Partially Effective: bleeding episodes most often required more injections and/or higher doses than expected or adequate breakthrough bleeding prevention during prophylaxis required more frequent injections and/or higher doses and 4=Ineffective: routine failure to control hemostasis/hemostatic control require additional agents. Total number of scale responses =total count of scale responses for all participants; multiple responses per participant including those at scheduled and unscheduled visits are counted.
Approximately 5 years
Participant's Assessment of Response (Excellent or Good Response) to rFIXFc Injections for the Treatment of Bleeding Episodes Using a 4-Point Scale
Временное ограничение: Approximately 5 years
Using eDiary, participant received rating for treatment response to any bleeding episode (BE) using 4-point scale- 1=Excellent: Abrupt pain relief and/or improvement in signs of bleeding within approximately (approx.) 8 hours (h) after initial injection (inj.); 2=Good: Definite pain relief and/or improvement in signs of bleeding within approx. 8h after an injection, but possibly requiring more than 1 injection after 24-48h for complete resolution; 3=Moderate: Probable/slight beneficial effect within 8h after initial injection and requires more than 1 injection and 4=None: No improvement, or condition worsens within approx. 8h after initial injection. This assessment was to be made approx. 8 to 12h from time the injection was given to treat BE and prior to any additional doses of rFIXFc given for same bleeding episode. Percentages are based on the number of bleeding episodes for which a response (excellent or good) was provided for the first injection during the efficacy period.
