Primary Outcome Measures:
  • Efficacy Assessment After a Total of at Least 50 EDs Per Subject at the End of the Study at 6 Months [ Time Frame: At least 50 Exposure Days and at least 6 months ]
    Frequency of spontaneous breakthrough bleeds/months under prophylactic treatment.

  • Efficacy of Treating Bleeding Episodes [ Time Frame: After each bleeding episode, up to 6 month ]

    At the end of a bleeding episode, efficacy was assessed as:

    • Excellent: Abrupt pain relief and/or unequivocal improvement in objective signs of bleeding within approximately 8 hours after a single infusion
    • Good: Definite pain relief and/or improvement in signs of bleeding within approximately 8-12 hours after an infusion requiring up to 2 infusions for complete resolution
    • Moderate: Probable or slight beneficial effect within approximately 12 hours after the first infusion requiring more than two infusions for complete resolution
    • None: No improvement within 12 hours, or worsening of symptoms, requiring more than 2 infusions for complete resolution Efficacy was rated
