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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Description of intervention(s) / exposure
Treatment: Other - rVIII-SingleChain
Treatment: Other - Octocog alfa

Experimental: Recombinant Factor VIII (rFVIII) -


Treatment: Other: rVIII-SingleChain
In Part 1 of the study, subjects received a single intravenous infusion of 50 IU/kg recombinant, single-chain coagulation factor VIII (rVIII-SingleChain) preceded by a 4-day washout period. In Parts 2 and 3 of the study, subjects received repeat injections of rVIII-SingleChain either as an on-demand or prophylaxis regimen at a dose and frequency determined by their study doctor. Subjects participating in the Part 3 PK analyses received a single infusion of 50 IU/kg rVIII-SingleChain and a repeat dose of the same strength of rVIII-SingleChain after 3 to 6 months. Subjects from Parts 2 and 3 participating in the surgical substudy received an individualized dose regimen of rVIII-SingleChain, based on the type of surgery and the clinical status of the subject.

Treatment: Other: Octocog alfa
In Part 1 of the study, subjects received a single intravenous infusion of 50 IU/kg of octocog alfa preceded by a 4-day washout period. Octocog alfa is the international nonproprietary name (INN) for recombinant human coagulation factor VIII.

Summary
Brief summary
This is an open-label, non-randomized, efficacy, safety and pharmacokinetic (PK) study comparing octocog alfa and rVIII-SingleChain. The study consists of three parts, a PK period (Part 1), a continuation of dosing safety and efficacy period (Part 2) and a safety, efficacy, and repeat PK period (Part 3) and also includes a surgical sub-study for subjects enrolled in Parts 2 and 3.
