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.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.

INTERVENTIONAL

Intervention Type : BIOLOGICAL
Intervention Description : 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.

Intervention Arm Group : Recombinant Factor VIII (rFVIII);

Intervention Type : BIOLOGICAL
Intervention Description : 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.
