Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this study was to describe the time to tolerization (i.e., ITI success) with rFVIIIFc in participants within a maximum of 48 weeks (12 months) of ITI treatment.

Recombinant coagulation factor VIII Fc (rFVIIIFc)

Participants were to receive rFVIIIFc at a dose of 200 international units (IU)/kilogram (kg) as once daily injections or divided on several injections per day at the discretion of the Investigator, starting at baseline visit up to maximum of 48 Weeks in ITI Period. Participants who met the criteria for immune tolerance induction (ITI) success entered the tapering period and received rFVIIIFc at a dose adjusted according to Investigator judgment based on the FVIII activity levels and with the aim of tapering the rFVIIIFc dose to reach a prophylactic dosing regimen within 16 weeks (4 months). Follow-Up was for 32 weeks under an adjusted prophylactic regimen according to Investigator judgment.

Group Type EXPERIMENTAL

rFVIIIFc

Intervention Type BIOLOGICAL

rFVIIIFc 200 IU/kg/day in ITI Period, 50 or 100 IU/kg (adjusted according to Investigator judgement) in tapering Period, and prophylactic regimen in Follow-Up period as powder for injection administered intravenously.
