Outcome

Type	Measure	Description	Time frame	Safety issue
Other	The Occurrence of Any Adverse Event (AE)	The frequency of AEs, as monitored throughout the whole study by the number of patients with at least one adverse event occurrence.	5 years
Primary	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 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.	maximum 5 years (100 exposure days)
Secondary	Frequency of Spontaneous Break-through Bleeds	The annualized bleeding rate (ABR) was calculated during inhibitor-free periods for spontaneous bleeding events (BEs) during prophylactic treatment with Human cl rhFVIII	Maximum 5 years (100 exposure days)
Secondary	Efficacy of Human-cl rhFVIII for the Treatment of Bleeds	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).	Maximum 5 years (100 exposure days)
Secondary	Efficacy of Human-cl rhFVIII for Surgical Prophylaxis	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).	Maximum 5 years (100 exposure days)
