Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Total Annualised Bleeding Rate (TABR) During Prophylactic Treatment With Wilate. | During 12 months of prophylactic treatment | TABR is defined as the total number of bleeding episodes (BEs) including spontaneous, traumatic, and other bleeds, occurring during the period from the first prophylactic dose of wilate to the study completion visit, divided by the duration (in years) between these two time points. Bleeding episodes that occurred during surgery periods were excluded from the calculation of TABR. Total BEs refers to all bleeding episodes that occurred during the study period, regardless of whether they were treated with wilate or not. Treated BEs are a subset of total BEs comprising of bleeding episodes that were treated with wilate. |
| Secondary | Area Under the Curve (AUC) of Wilate for VWF:Ac (VWF:RCo) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean AUC of VWF:Ac after PK injection of wilate as measured by chromogenic assay. |
| Secondary | Area Under the Curve (AUC) of Wilate for FVIII (OS) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean AUC of FVIII after PK injection of wilate as measured by chromogenic assay. |
| Secondary | AUC Normalised for the Administered Dose (AUCnorm) of Wilate for VWF:Ac (VWF:RCo) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean AUC of VWF:Ac after PK injection of wilate, normalised for the actual administered dose (IU/kg), over time. AUC norm was measured and reported as \[h\*kg/IU\]/(dL/IU) which could also be reported as h\*kg/dL. |
| Secondary | AUC Normalised for the Administered Dose (AUCnorm) of Wilate for FVIII:C (OS) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean AUC of FVIII after PK injection of wilate, normalised for the actual administered dose (IU/kg), over time. AUC norm was measured and reported as \[h\*kg/IU\]/(dL/IU) which could also be reported as h\*kg/dL. |
| Secondary | Clearance (CL) of Wilate for VWF:Ac (VWF:RCo) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean clearance (CL) of VWF:Ac, measured by ristocetin cofactor assay \[VWF:RCo\]) after PK injection of wilate, calculated as the ratio of dose administered to the area under the plasma concentration-time curve (AUC), over time. Clearance was defined as the rate of drug elimination divided by plasma concentration, giving a volume of plasma from which drug is completely removed per unit of time. |
| Secondary | Clearance (CL) of Wilate for FVIII:C (OS) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean clearance (CL) of FVIII:C, measured by one-stage assay \[OS\]) after PK injection of wilate, calculated as the ratio of dose administered to the area under the plasma concentration-time curve (AUC), over time. |
| Secondary | Maximum Plasma Concentration (Cmax) of Wilate for VWF:Ac (VWF:RCo) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean maximum plasma concentration (Cmax) of VWF:Ac, measured by ristocetin cofactor assay \[VWF:RCo\]) after PK injection of wilate, as determined from the observed peak value in the plasma concentration-time profile. |
| Secondary | Maximum Plasma Concentration (Cmax) of Wilate for FVIII:C (OS) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean maximum plasma concentration (Cmax) of FVIII:C, measured by one-stage assay \[OS\]) after PK injection of wilate, as determined from the observed peak value in the plasma concentration-time profile. |
| Secondary | Mean Residence Time (MRT) of Wilate for VWF:Ac (VWF:RCo) Over Time | At baseline, 15 minutes, 3, 9, 24, 48 and 72 hours after dosing of 80 IU/kg BW wilate | Mean residence time (MRT) of VWF:Ac, measured by ristocetin cofactor assay \[VWF:RCo\]) after PK injection of wilate, calculated as the average time a VWF:Ac molecule remains in the body, derived from the ratio of area under the first moment curve (AUMC) to AUC. |
