Study Population
About 300 at most hemophilia boys (2-<18 years) in the representative hemophilia treatment centers (HTCs) with available medical data record, having received rFVIII contained regular prophylaxis between Nov. 1st 2007 and May 31st 2013 will be enrolled from about 15 centers.

Inclusion Criteria:

  • Male, 2-<18 years Hemophilia A, based on documented prior testing and/or screening laboratory Patients who had received regular prophylaxis/bleeding prevention treatment, totally/partially with rFⅧ. Regular prophylaxis/bleeding prevention treatment is defined as that proportion of weeks (≥2 infusion/week) of total treatment weeks≥80%[10] , and total duration ≥12 weeks. During the regular prophylaxis period, if there were consecutive 4 weeks that <2 infusion/week, the beginning day of the 4 weeks is defined as the end of regular prophylaxis.

Available patient medical data record Written informed consent by parent/legal representative. Consent should be sought from subjects if appropriate

Exclusion Criteria:

  • Patients with measurable inhibitor activity at baseline and history of FVIII inhibitor antibody formation (≥0.6BU by Bethesda assay at two different time points, documentation must be available) Any individuals with another bleeding disease that is different from hemophilia A (e.g, von Willebrand disease, hemophilia B)
