the aim of the SERAPHINE study is to gather data stemming from the French research database BERHLINGO (= Base d'Etude et de Recherche en Hémostase pour Les Investigateurs du Grand-Ouest, i.e. Database for Research on Hemostasis for the Investigators of Western France), in order to get a detailed report about the therapeutic management and use of turoctocog alfa (NovoEight®) in surgery in pwHA (Patient with inherited Hemophilia A).

Inclusion Criteria:

• Male or female
• Regardless of age
• No inhibitor (anti-FVIII alloantibodies) at the time of treatment.
• No objections expressed to participate in the study after having been informed of its purposes and the data involved.
• No other inherited hemorrhagic disorders than HA

Exclusion Criteria:

In order to reflect the reality of daily practice, no criteria for non-inclusion are provided for other than the refusal of the patient or his or her legal representative to participate in the study or the existence in the patient of a contraindication to the use of turoctocog alfa (NovoEight®) treatment.

In order to respect the independence of the physicians, this study is conducted with patients for whom the decision to prescribe turoctocog alfa (NovoEight®) treatment is not related to the study. The prescription of turoctocog alfa (NovoEight®) will therefore have been carried out on the initiative of the physicians of the participating centers, in collaboration with the patients involved. This study therefore does not lead to any change in the usual medical care of the people entering the study, nor does it affect the physical or psychological integrity of the patients.
