Primary Outcome Measures:
  • Adverse events: Non-serious adverse events occurring from the first administration of trial product [ Time Frame: until 7 days after first trial product administration. ] [ Designated as safety issue: Yes ]
  • Serious adverse events are collected form the first trial product administration of trial product [ Time Frame: to the end of subjects participation (up to maximum 24 months) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pharmacokinetic parameter: Activated recombinant human factor VII analogue activity in the blood (IU/ml) [ Time Frame: 0-24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Coagulation related parameter- Prothrombin Time (PT) [ Time Frame: predose- 24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Coagulation related parameter: F1 + 2 (Prothrombin Fragments 1+2) [ Time Frame: predose- 24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Coagulation related parameter- activated Partial Thromboplastin Time (aPTT) [ Time Frame: Predose- 24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Cessation of bleeding: Number of doses needed to control bleeding. Need evaluated after each of 1-3 doses [ Time Frame: Within 9 hours after first trial product administration or need of additional haemostatic medication within 9 hours after first trial administration additional haemostatic agents required to control bleed (treatment failure) ] [ Designated as safety issue: No ]
  • Need for additional haemostatic agents [ Time Frame: within 24 hours after succesful control of bleeding episode with trial product ] [ Designated as safety issue: No ]
  • Pharmakokinetic parameters based on FVlla activity: AUC 0-t (Area under the plasma FVIIa activity-time curve from time zero to the time (t) ) and AUC (Area under the plasma FVIIa activity-time curve from time zero to infinity) [ Time Frame: 0-24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Pharmakokinetic parameters based on FVlla activity: MRT (Mean residence time) [ Time Frame: 0-24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Pharmakokinetic parameters based on FVlla activity: t½ (Terminal half-life) [ Time Frame: 0-24 hours after trial product administration ] [ Designated as safety issue: No ]
  • Pharmakokinetic parameters based on FVlla activity: CL (Total clearance) [ Time Frame: 0-24 hours after trial product administration ] [ Designated as safety issue: No ]
