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.

Participant, male or female, must be equal to or greater than 12 years of age inclusive, at the time of signing the informed consent.
Severe hemophilia A, defined as less than (\<) 1 international units per deciliter (IU/dL) (\<1 percent \[%\]) endogenous FVIII activity as documented either by central laboratory testing at Screening or in historical medical records from a clinical laboratory demonstrating \<1% FVIII coagulant activity (FVIII:C) or a documented genotype known to produce severe hemophilia A.
Previous treatment for hemophilia A (prophylaxis or on demand) with any recombinant and/or plasma-derived FVIII, or cryoprecipitate for at least 150 exposure days.
Current regimen included one of the following:
* Prophylactic treatment regimen with a FVIII product or prophylactic emicizumab therapy for at least 6 months during the previous 12 months. Appropriate washout time needs to be taken into account.
* On-demand regimen with a FVIII product with a history of at least 12 bleeding episodes in the previous 12 months or at least 6 bleeding episodes in the previous 6 months prior to study enrollment.
On-demand participant was accepted to move to a prophylaxis treatment regimen after 26-week on-demand period.
Willingness and ability of the participant or surrogate (a caregiver or a family member greater than or equal to \[\>=\] 18 years of age) to complete training in the use of the study electronic Patient Diary (ePD) and to use the ePD throughout the study.
Ability of the participant or his or her legally authorized representative (eg., parent or legal guardian) to understand the purpose and risks of the study, willing and able to comply with study requirements and provide signed and dated informed consent or assent (as applicable) and authorization to use protected health information in accordance with national and local participant privacy regulations.
You may not be if
Clinically significant liver disease.
Serious active bacterial or viral infection (other than chronic hepatitis or HIV) present within 30 days of screening.
Other known coagulation disorder(s) in addition to hemophilia A.
History of hypersensitivity or anaphylaxis associated with any FVIII product.
Positive inhibitor results, defined as \>=0.6 Bethesda unit per milliliter (BU/mL) at screening. History of a positive inhibitor test defined as \>=0.6 BU/mL. Family history of inhibitors would not exclude the participant.
Use of Emicizumab within the 20 weeks prior to screening.
Major surgery within 8 weeks prior to screening.
The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
