Description of intervention(s) / exposure
Treatment: Drugs - efanesoctocog alfa (BIVV001)

Experimental: Arm A: Previously treated in BIVV001 study - This arm includes all participants who have completed the previous phase 3 studies on BIVV001, as well as participants who have completed Arm B or Arm C of this study rolling over in Arm A, and participants who will have completed any future BIVV001 study who will be proposed to continue BIVV001 treatment. Participants in this arm will continue receiving BIVV001 prophylaxis treatment once-weekly (QW) for a total of 100 exposure days (EDs) cumulative from the parent study and this study. Participants will have the opportunity to continue in this study for up to 4 years, unless BIVV001 is commercially available in their applicable participating country.

Experimental: Arm B: Newly initiated (China Only) in BIVV001 - This arm includes Chinese participants of any age who will be newly initiated on BIVV001 prophylaxis treatment once-weekly (QW) for 52 weeks. After 52 weeks of treatment in this arm B, participants will be able to roll into arm A.

Experimental: Arm C: Newly initiated in BIVV001 with planned major surgery - This arm includes participants of any age who will be newly initiated on BIVV001 prophylaxis treatment once-weekly (QW) and will undergo planned major surgery after at least 6 initial EDs with BIVV001, and within 26 weeks from Day 1. After 52 weeks of treatment in arm C, participants will be able to roll into arm A.

signs or symptoms of decreased response to FVIII administrations. Family history

Summary
Brief summary
Primary Objective:

- To evaluate the long-term safety of BIVV001 in previously treated subjects with hemophilia
A

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 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 (QoL) outcomes.

- To evaluate the safety and tolerability of BIVV001 treatment.

- To assess the PK of BIVV001 based on the one stage activated partial thromboplastin time
(aPTT) and two-stage chromogenic FVIII activity assays (only applicable to Arm B).

- To evaluate the efficacy of BIVV001 for perioperative management
