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).

Arms Assigned Interventions
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)
