Study type
Interventional
Description of intervention(s) / exposure
Experimental: Individualized (Tailored) Prophylaxis - On rFVIIIFc Day 0, all participants underwent pharmacokinetic (PK) analysis with 50 IU/kg rFVIIIFc to estimate their PK parameters and guide the appropriate dose or interval of dosing. A subset of participants (Sequential PK subgroup) also had PK analyses performed with a single dose of 50 IU/kg Advate (Advate Day 0) within 8 weeks prior to rFVIIIFc Day 0. A \>= 96 hour washout was performed before the PK dose of Advate or rFVIIIFc was administered. Repeat PK profiling with a single dose of 50 IU/kg rFVIIIFc was conducted at Week 14 or after 12 to 24 weeks of prophylaxis with rFVIIIFc.

After PK assessments, all participants started twice weekly treatment with 25 IU/kg of rFVIIIFc via intravenous (IV) injection on Day 1 and 50 IU/kg on Day 4, followed by individualized dose and interval modification within the range of 25 to 65 IU/kg every 3 to 5 days, as determined by rFVIIIFc PK analysis, to maintain a trough level of 1% to 3% (or higher, as clinically indicated) FVIII activity.

Experimental: Weekly Prophylaxis - 65 IU/kg of rFVIIIFc via IV injection every 7 days

Experimental: Episodic (On-Demand) Dosing - 10 to 50 IU/kg rFVIIIFc via IV injection, as required to treat a bleeding episode
