Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Study type

Description of intervention(s) / exposure
Treatment: Other - rFVIIIFc

Experimental: rFVIIIFc - Participants were to receive rFVIIIFc as follows- Prophylaxis regimen (PR): rFVIIIFc 25-80 international units per kilogram (IU/kg), at 3- to 5-day intervals until participant reached greater than or equal to (\>=) 50 exposure days (ED: 24-hour period in which \>=1 injection/dose of rFVIIIFc was given), or study withdrawal/end of study. Adjustments to dose/dosing interval was done as needed by investigator; Treatment with an optional ER (Episodic regimen) can be initiated before PR at investigators discretion; ITI: rFVIIIFc 200 IU/kg, daily for participants who, after exposure to rFVIIIFc, had positive high titer inhibitor (\>=5.00 Bethesda Units per milliliter \[BU/mL\]) or positive low titer inhibitor (\>=0.60 and \<5.00 BU/mL) and had poorly controlled bleeding despite increased rFVIIIFc doses, or required bypassing agent to treat bleeding.

Eligibility
Key inclusion criteria
Key

* Ability of the participant's legally authorized representative (e.g. their parent or legal guardian) to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use confidential health information in accordance with national and local participant privacy regulations.
* Weight >=3.5 kg at the time of screening.
* Severe hemophilia A defined as less than (<) 1 IU/dL (<1%) endogenous FVIII documented in the medical record or as tested during the Screening Period.

Key
Minimum age
No limit
Maximum age
5 Years
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
* Any exposure to blood components, factor VIII replacement products, including commercially available rFVIIIFc at any time prior to or during screening.
* History of positive inhibitor testing. A prior history of inhibitors was defined based on a patient's historical positive inhibitor test using the local laboratory Bethesda value for a positive inhibitor test (ie, equal to or above lower level of detection).
* History of hypersensitivity reactions associated with any rFVIIIFc administration.
* Other coagulation disorder(s) in addition to hemophilia A.
* Any concurrent clinically significant major disease that, in the opinion of the Investigator, would make the participant unsuitable for enrollment.
* Current systemic treatment with chemotherapy and/or other immunosuppressant drugs.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Summary
Brief summary
The primary objective of the study was to evaluate the safety of rFVIIIFc (BIIB031) in previously untreated participants (PUPs) with severe hemophilia A. The secondary objectives were to evaluate the efficacy of rFVIIIFc in the prevention and treatment of bleeding episodes in PUPs, to evaluate rFVIIIFc consumption for the prevention and treatment of bleeding episodes in PUPs, and to describe experience with the use of rFVIIIFc for immune tolerance induction (ITI) in participants with inhibitors.
