Experimental: Pharmacokinetic (PK) evaluation of BAX 855 - Participants will first undergo an initial pharmacokinetic (PK) assessment. Following the PK assessment participants will be randomized to one of 2 dosing regimens.

Experimental: FVIII trough target 1-3% - Standard treatment arm - PK-guided dosing schedule to achieve a Factor VIII (FVIII) trough of 1-3%

Experimental: FVIII trough target 8-12% - Intensified treatment arm - PK-guided dosing schedule to achieve a Factor VIII (FVIII) trough of 8-12%
