- Immunogenicity of Human-cl rhFVIII: Incidence of Inhibitors [ Time Frame: maximum 5 years (100 exposure days) ]The number of patients developing FVIII inhibitors was observed during the observation period by assessing inhibitor development using the modified Bethesda assay (Nijmegen modification). The definitions for thresholds were ≥0.6 to <5 BU/mL for a "low titre" inhibitor and ≥5 BU/mL for a "high-titre" inhibitor.
- Frequency of Spontaneous Break-through Bleeds [ Time Frame: Maximum 5 years (100 exposure days) ]The annualized bleeding rate (ABR) was calculated during inhibitor-free periods for spontaneous bleeding events (BEs) during prophylactic treatment with Human cl rhFVIII
- Efficacy of Human-cl rhFVIII for the Treatment of Bleeds [ Time Frame: Maximum 5 years (100 exposure days) ]A personal efficacy assessment to assess the efficacy of Human-cl rhFVIII for the on-demand treatment of bleeding episodes. Efficacy was assessed using a four-point scale (excellent, good, moderate, none).
- Efficacy of Human-cl rhFVIII for Surgical Prophylaxis [ Time Frame: Maximum 5 years (100 exposure days) ]An overall efficacy assessment to assess the efficacy of human-cl rhFVIII in surgical prophylaxis of minor and major surgeries. The efficacy assessment was analyzed using a four-point scale (excellent, good, moderate, none).
- The Occurrence of Any Adverse Event (AE) [ Time Frame: 5 years ]The frequency of AEs, as monitored throughout the whole study by the number of patients with at least one adverse event occurrence.
