结局指标
主要结局
The Area Under the Concentration Curve for Human-cl rhFVIII Compared to Kogenate FS
时间窗: 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.
次要结局
- Time to Reach Maximum Plasma Concentration (Tmax) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Mean Residence Time (MRT) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Volume of Distribution at Steady State (Vss) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Clearance (CL) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Efficacy of On-demand Treatment of Bleeding Episodes(From 1st treatment after PK cycle 2 until study end.)
- Invivo Half-life (T1/2) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Maximum Plasma Concentration (Cmax) for Human-cl rhFVIII Compared to Kogenate FS(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.)
- Immunogenicity (Number of Patients That Developed an Inhibitor During the Course of the Study)(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)
