Outcome Measures
Primary Outcomes (1)
Immunogenicity of Human-cl rhFVIII: Incidence of Inhibitors
The number of patients developing FVIII inhibitors was observed during the observation period by assessing inhibitor development by the modified Bethesda assay (Nijmegen modification) using congenital FVIII-deficient human plasma spiked with Human-cl rhFVIII. The definition threshold for a "positive" inhibitor was if the modified Bethesda assay resulted in a titre ≥0.6 BU/mL at any time point during the observation period.
Maximum two years
Secondary Outcomes (4)
Frequency of Spontaneous Break-through Bleeds
Maximum 2 years
Efficacy of Human-cl rhFVIII for the Treatment of Bleeds
Maximum 2 years
Efficacy of Human-cl rhFVIII for Surgical Prophylaxis
Maximum 2 years
The Occurrence of Any Adverse Event (AE)
Maximum 2 years
