Arm	Intervention/treatment
Experimental: N8-GP	Drug: turoctocog alfa pegol; Fixed dose of turoctocog alfa pegol for intravenous injections (i.v.) twice weekly for prophylaxis. In addition, turoctocog alfa pegol will be administered to treat bleeding episodes during the trial period. Bleeding episodes will be treated with doses of 20-75 U/kg body weight.; Other Names: NNC 0129-0000-1003; N8-GP
