This trial is conducted in Asia, Europe, Japan, Oceania, North America and South America.
The aim of the trial is to investigate the safety and efficacy of turoctocog alfa (N8) in Haemophilia A patients.
The trial is an extension to trials NN7008-3543 (start: March 2009, stop: September 2011) and NN7008-3545 (start: May 2010, stop: November 2011) and the pharmacokinetic trials NN7008-3600 (start: November 2010, stop: October 2011), NN7008-3893 (start: June 2011, stop: September 2011) and NN7008-4015 (start: August 2012, stop: March 2013).

|Experimental: Turoctocog alfa||
Drug: turoctocog alfa
The preventative treatment is administered intravenously (i.v.) at specific intervals either every second day or three times a week. Bleeding treatment will be administered if a bleed should occur.Drug: turoctocog alfa
Treatment is administered intravenously (i.v.) during bleeds and occasionally as a preventative treatment (e.g. before physical activity)
- Frequency of Development of FVIII Inhibitors (Greater Than or Equal to 0.6 Bethesda Units (BU)/mL) [ Time Frame: After 90 months ]The frequency of inhibitors was calculated as number of patients with inhibitors during the trial divided by number of patients in the trial. This endpoint was measured during the trial.
- Frequency of Adverse Events and Serious Adverse Events [ Time Frame: After 90 months ]The number of adverse events and serious adverse events reported during the main trial and the on-demand sub-trial (during 90 months).
- Annualised Bleeding Rate Reported During the Prevention Period (Only Applicable for Subjects in the Preventive Regimen) [ Time Frame: After 90 months ]The number of bleeding episodes per year reported during the prevention period (during 90 months).
- Haemostatic Response to Turoctocog Alfa (None, Moderate, Good or Excellent) in Treatment of Bleeds. [ Time Frame: After 90 months ]Haemostatic response to turoctocog alfa (none, moderate, good or excellent) in treatment of bleeds using a four-point response scale: none, moderate, good or excellent. The evaluation was done by patient, caregiver and/or investigator based on experience as follows: 1. Excellent: Abrupt pain relief and/or unequivocal improvement in objective signs of bleeding within approximately 8 hours after a single infusion 2. Good: Definite pain relief and/or improvement in signs of bleeding within approximately 8 hours after an infusion, but possibly requiring more than 1 infusion for complete resolution. 3. Moderate: Probable or slight beneficial effect within approximately 8 hours after the first infusion; usually requiring more than 1 infusion. 4. None: No improvement, or worsening of symptoms. This endpoint is measured during the preventive and on-demand sub-trial (during 90 months).
