Primary Outcome Measures:
  • Percentage of Participants With Less Than 2 Joint Bleeds During the 9-month Treatment Period [ Time Frame: Up to 9 months ]

Secondary Outcome Measures:
  • Number of Bleeds Per Participant During the 9-month Treatment Period [ Time Frame: Up to 9 months ]
  • Number of Participants With Bleeding Events During the 9-month Treatment Period [ Time Frame: Up to 9 months ]
  • Number of Participants With Joint Bleeds During the 9-month Treatment Period [ Time Frame: Up to 9 months ]
  • Number of Participants in Each Group at the End of the Study [ Time Frame: Up to 9 months ]
  • Actual Monthly rFVIII-FS Consumption [ Time Frame: Up to 9 months ]
  • Change From Baseline in Stockholm Hemophilia Joint Score at 9 Months of Treatment [ Time Frame: baseline and 9 months ]
    The assessment of joint function using Stockholm Joint Score. The minimum value is 0 (the best condition), and the maximum value is 140 (the worst condition).

  • Haemo-QoL Standardized Total Score at 9 Months of Treatment (Completed by Participants in the Total Group) [ Time Frame: 9 months ]
    Quality of life (QoL) was measured by the Haemo-QoL standardized total Score, which ranged from 0 (the best condition) to 100 (the worst condition).

  • Haemo-QoL Standardized Total Score (Completed by Parents/Caregivers in the Total Group) at 9 Months of Treatment [ Time Frame: 9 months ]
    Quality of life (QoL) was measured by the Haemo-QoL standardized total Score, which ranged from 0 (the best condition) to 100 (the worst condition).
