This trial is conducted in Asia, Europe, and North and South America. The aim of this clinical trial is to investigate the safety and efficacy of turoctocog alfa (recombinant factor VIII, rFVIII (N8)) in male previously treated paediatric subjects with haemophilia A.

Primary Outcome Measures:
  • The Incidence Rate of FVIII Inhibitors (Greater Than or Equal to 0.6 Bethesda Units (BU)) [ Time Frame: The adverse events were collected throughout the trial, corresponding to an average of 138 days per subject. ]
    The incidence rate of FVIII inhibitors was calculated by including all patients with inhibitors in the nominator and including all patients with a minimum 50 exposure plus any patients with less than 50 exposures but with inhibitors in denominator.

Secondary Outcome Measures:
  • Frequency of Adverse Events (AEs) [ Time Frame: The adverse events were collected throughout the trial, corresponding to an average of 138 days per subject ]
    Adverse event was defined as events occurring after administration of trial product. Severe AEs: considerable interference with subject's daily activities, unacceptable. Moderate AEs: Marked symptoms, moderate interference with the patient's daily activities. Mild AEs: No or transient symptoms, no interference with the patient's daily activities. Serious AE: AE that at any dose results in any of the following: death, a life-threatening experience, in-subject hospitalization/prolongation of existing hospitalisation, persistent/significant disability/incapacity/congenital anomaly/birth defect.

Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: rFVIII Drug: turoctocog alfa
Subjects will be treated 3 times per week or every second day with intravenous injections of turoctocog alfa. The dose range for preventive treatment is 25-60 IU/kg body weight depending on treatment regimen.
Drug: turoctocog alfa
Subjects will undergo half-life evaluation of their current factor VIII product and pharmacokinetic session with turoctocog alfa before entering preventive treatment (subjects with available evaluation of terminal half-life within the last year are to be excluded from receiving factor VIII). Intravenous injections. The dose range for preventive treatment is 25-60 IU/kg body weight depending on treatment regimen.
