Eksperimentell: Human-cl rhFVIII
Recombinant FVIII derived from a human cell line.
|
Human-cl rhFVIII is administered intravenously on demand for bleeding episodes and prophylactically in case of surgery.
The dosage depends on the severity of the bleeding episodes and the surgery.

To Determine Long-term Efficacy of Human-cl rhFVIII in the Treatment of Bleeding Episodes and in Surgical Prophylaxis
Tidsramme: up to 3 years
|
The efficacy of human-cl rhFVIII will be determined using a 4 point efficacy assessment scale. After each infusion of IMP and at the end of a BE, the following efficacy assessment is made by the subject (together with the Investigator in case of on-site treatment): 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. The assessment was made at the end of a BE in case more than one infusion was needed. |
