The Area Under the Concentration Curve for Human-cl rhFVIII Compared to Kogenate FS
Ramy czasowe: At baseline (prior to infusion), 0.25, 0.5, 0.75, 1, 3, 6, 9, 12, 24, 30 and 48 hours after the end of the infusion.
|
After the infusion of 50IU/kg bw of Human-cl rhFVIII and Kogenate FS respectively, FVIII activity levels were measured at various time points before and after the infusion.
FVIII level results derived from the chromogenic FVIII assay were used to calculate the mean of the area under the curve normalized to the dose administered.

Efficacy of On-demand Treatment of Bleeding Episodes
Ramy czasowe: From 1st treatment after PK cycle 2 until study end.
|
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. |
From 1st treatment after PK cycle 2 until study end.

Immunogenicity (Number of Patients That Developed an Inhibitor During the Course of the Study)
Ramy czasowe: study entry, then immediately before both PK cycles, in the 48 hour sample of both PK cycles, after 10 to 15 EDs with human-cl rhFVIII, at the 3-month visit (± 2 weeks), then every 3 months (± 2 weeks) until study completion, and after >50 EDs (except for

Inhibitor activity was determined by the modified Bethesda assay (Nijmegen modification) at study entry, then immediately before both PK cycles, in the 48 hour sample of both PK cycles, after 10 to 15 EDs with human-cl rhFVIII, at the 3-month visit (± 2 weeks), then every 3 months (± 2 weeks) until study completion, and after >50 EDs (except for some patients who may finish the study before they achieve 50 EDs), with human-cl rhFVIII (i.e. at the study completion visit).
