Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Interventional
Description of intervention(s) / exposure
Treatment: Drugs - BIIB031 (rFVIIIFc)
Treatment: Drugs - FVIII (PK subgroup only)

Experimental: All participants - PK subgroup: After a Washout Period of =72 hours, at the Baseline Visit (28±7 days prior to Day 1), participants receive a single IV injection of prestudy FVIII over 5 (±2) minutes at a dose of 50 IU/kg, rounded up to the nearest 250 IU increment, for a PK assessment. Following a second Washout Period of =72 hours, participants receive a single IV injection of rFVIIIFc over 5 (±2) minutes at a dose of 50 IU/kg for PK assessment. The first prophylactic dose of rFVIIIFc is administered at a starting dose of 25 IU/kg IV injection on Day 1 and 50 IU/kg on Day 4. Dose increases to a maximum of 80 IU/kg, and frequency of administration to a minimum interval of once every 2 days, are allowed as indicated.

Non-PK subgroup: On Day 1, a first prophylactic dose of rFVIIIFc of 25 IU/kg IV injection is given, followed by a dose of 50 IU/kg on Day 4. Dose increases to a maximum of 80 IU/kg, and frequency of administration to a minimum interval of once every 2 days, are allowed as indicated.


Treatment: Drugs: BIIB031 (rFVIIIFc)
Vials of rFVIIIFc were combined as needed, based on the actual labeled potency to achieve the participant's calculated dose. Partial vial use was allowed, in order to achieve the calculated dose.

Treatment: Drugs: FVIII (PK subgroup only)
Baseline prestudy FVIII dosing in participants who enter the PK subgroup. Vials of prestudy FVIII were combined as needed, based on the nominal labeled potency (e.g., 250 IU, 500 IU, and 1000 IU), to achieve the participant's calculated dose.
