Outcome Measures
Primary Outcomes (1)
Percentage of Participants With a Total Annualized Bleeding Rate (ABR) of Zero for Second Six Months
Annualized bleeding rate was determined by dividing the number of bleeds by observation period in years.
Day 183 to Day 364 (6 months)
Secondary Outcomes (25)
Total Annualized Bleeding Rate for Second Six Months
Day 183 to Day 364 (6 months)
Annualized Spontaneous Bleeding Rate for Second Six Months
Day 183 to Day 364 (6 months)
Annualized Traumatic Bleeding Rate for Second Six Months
Day 183 to Day 364 (6 months)
Annualized Joint Bleeding Rate (AJBR) for Second Six Months
Day 183 to Day 364 (6 months)
Total Weight-adjusted Consumption of BAX 855
From start of study treatment up to 12 months (completion or termination)
- +20 more secondary outcomes
Study Arms (3)
Pharmacokinetic (PK) evaluation of BAX 855
EXPERIMENTALParticipants will first undergo an initial pharmacokinetic (PK) assessment. Following the PK assessment participants will be randomized to one of 2 dosing regimens.
FVIII trough target 1-3%
EXPERIMENTALStandard treatment arm - PK-guided dosing schedule to achieve a Factor VIII (FVIII) trough of 1-3%
FVIII trough target 8-12%
EXPERIMENTALIntensified treatment arm - PK-guided dosing schedule to achieve a Factor VIII (FVIII) trough of 8-12%
