*ELOCTATE has been proven to help patients prevent bleeding episodes using a prophylaxis regimen.1
In the Kids A-LONG study, individualized prophylaxis regimen: 25 IU/kg and 50 IU/kg of ELOCTATE on the first and fourth days of the week, respectively. Adjustments in dose (25 to 80 IU/kg) and interval (every 2 days or longer) were allowed based on a subject’s available PK data and observed bleeding pattern.4
In the ASPIRE study, the individualized prophylaxis regimen was 25 to 65 IU/kg every 3 to 5 days, or twice weekly (20 to 65 IU/kg on Day 1, 40 to 65 IU/kg on Day 4). In subjects <12 years of age, dose adjustments were made up to a maximum of 80 IU/kg up to every 2 days, if necessary.5
† The median treatment duration from the beginning of Kids A-LONG to the end of ASPIRE was 3.5 years (range: 0 to 4.4 years).5
‡ A target joint is defined as a major joint with ≥3 bleeding episodes in a consecutive 6-month period. Target joint resolution is defined as ≤2 spontaneous bleeds in a 12-month period .6
§ Data are from the third interim cut of ASPIRE taken on January 11, 2016. 48 adult and adolescent patients and 7 pediatric patients had no target joint bleeding episodes.

*ELOCTATE has been proven to help patients prevent bleeding episodes using a prophylaxis regimen.1
In the A-LONG study, of 117 patients enrolled in the individualized prophylaxis arm, 112 were treated for ≥6 months. Dosing intervals were evaluated during the last 3 months of the study. Number of infusions may vary per individual. Individualized prophylaxis regimen: 25 IU/kg and 50 IU/kg of ELOCTATE on the first and fourth days of the week, respectively. Dose adjustments (25 to 65 IU/kg) and interval adjustments (every 3 to 5 days) were allowed based on a subject’s PK data and observed bleeding pattern.1
In the ASPIRE study, the individualized prophylaxis regimen was 25 to 65 IU/kg every 3 to 5 days or twice weekly (20 to 65 IU/kg on Day 1, 40 to 65 IU/kg on Day 4).2

Across A-LONG and ASPIRE, 22 patients underwent 24 major surgeries. One surgery was not evaluable because the patient received a nonstudy drug.

aAcross A-LONG and ASPIRE, 22 patients underwent 24 major surgeries. One surgery was not evaluable because the patient received a nonstudy drug.
bResults based on a 4-point scale of excellent, good, fair, and poor/none. The median dose per infusion was 58.3 IU/kg (range, 45–102 IU/kg). The total dose on the day of surgery ranged from 50.8 to 126.6 IU/kg.
cOne surgical rating was not available.
|| Major Surgeries: Hemostasis was assessed in 45 surgeries in 32 subjects from the A-LONG and ASPIRE studies. There were no major surgeries in the Kids A-LONG study. Of the 45 major surgeries, 36 surgeries (80.0%) required a single perioperative dose to maintain hemostasis. Of the 42 major surgeries treated with at least one dose, the median average dose per injection to maintain hemostasis during surgery was 59.1 IU/kg (range: 35–111). On the day of surgery, most subjects received a second injection. The total dose on the day of surgery ranged from 37.6–157.9 IU/kg.1
Minor Surgeries:
A hemostatic assessment of 72 minor surgical procedures in 59
subjects from all 3 studies was conducted. “Excellent”
was defined as intraoperative and postoperative blood loss similar
to (or less than) the nonhemophilic patient. No extra doses of
ELOCTATE needed, and blood component transfusions required are
similar to nonhemophilic patient. “Good” was defined as
intraoperative and/or postoperative bleeding slightly increased over
expectations for the nonhemophilic patient, but the difference was
not
clinically significant. Intraoperative blood loss no more than 250
mL greater than expected for a nonhemophilic patient, no extra doses
of
ELOCTATE needed, and blood component transfusions required are
similar to nonhemophilic patient.1
