Brief Summary:
Primary Objective:
\- To evaluate the efficacy of BIVV001 as a prophylaxis treatment in prophylaxis treatment arm.
Secondary Objectives:
* To evaluate the efficacy of BIVV001 as a prophylaxis treatment.
* To evaluate the efficacy of BIVV001 in the treatment of bleeding episodes.
* To evaluate BIVV001 consumption for the prevention and treatment of bleeding episodes.
* To evaluate the effect of BIVV001 prophylaxis on joint health outcomes.
* To evaluate the effect of BIVV001 prophylaxis on Quality of Life outcomes.
* To evaluate the efficacy of BIVV001 for perioperative management.
* To evaluate the safety and tolerability of BIVV001 treatment.
* To assess the pharmacokinetics (PK) of BIVV001 based on the 1-stage activated partial thromboplastin time (aPTT) and 2-stage chromogenic coagulation factor VIII (FVIII) activity assays.

Detailed Description:
Participants in prophylaxis arm received a weekly prophylactic dose of BIVV001 for 52 weeks. Participants in on-demand arm received BIVV001 on demand for 26 weeks followed by a switch to weekly prophylaxis for another 26 weeks.
The Sponsor planned to perform a long-term safety trial. Enrollment in this open-label extension study would be offered to participants completing the treatment period based on eligibility criteria.
