Trial Outcomes & Findings for Recombinant Von Willebrand Factor in Subjects With Severe Von Willebrand Disease Undergoing Surgery (NCT NCT02283268)
NCT ID: NCT02283268
Last Updated: 2021-05-19
Results Overview
Hemostatic efficacy will be rated on a scale of excellent - good - moderate - none. Excellent: Intra-, and postoperative hemostasis achieved with rVWF with our without ADVATE was as good or better than that expected for the type of surgical procedure performed in a hemostatically normal subject. Good: Intra-, and postoperative hemostasis achieved with rVWF with or without ADVATE was probably as good as that expected for the type of surgical procedure performed in a hemostatically normal subject. Moderate: Intra-, and postoperative hemostasis with rVWF with or without ADVATE was clearly less than optimal for the type of procedure performed but was maintained without the need to change the rVWF concentrate. None: Participant experienced uncontrolled bleeding that was the result of inadequate therapeutic response despite proper dosing, necessitating a change of rVWF concentrate.

PRIMARY outcome
Timeframe: 24 hours after last peri-operative infusion or at completion of Day 14 (± 2 days) visit, whichever occurs earlierPopulation: Number of participants with major, minor and oral surgery and number of participant with Von Willebrand Type 1, 2A, 2B, 2M and 3 do sum up to the overall number of participants analyzed. The full analysis data set, including all participants who received investigational product and have at least 1 hemostatic assessment, was used for analysis.
Hemostatic efficacy will be rated on a scale of excellent - good - moderate - none. Excellent: Intra-, and postoperative hemostasis achieved with rVWF with our without ADVATE was as good or better than that expected for the type of surgical procedure performed in a hemostatically normal subject. Good: Intra-, and postoperative hemostasis achieved with rVWF with or without ADVATE was probably as good as that expected for the type of surgical procedure performed in a hemostatically normal subject. Moderate: Intra-, and postoperative hemostasis with rVWF with or without ADVATE was clearly less than optimal for the type of procedure performed but was maintained without the need to change the rVWF concentrate. None: Participant experienced uncontrolled bleeding that was the result of inadequate therapeutic response despite proper dosing, necessitating a change of rVWF concentrate.

SECONDARY outcome
Timeframe: Day 0 (at completion of surgery)Population: For predicted blood loss the number of participants analyzed is 14 as for one participant (included in the major surgery reporting group) the predicted blood loss was not collected. The full analysis data set, including all participants who received investigational product and have at least 1 hemostatic assessment, was used for analysis.
The predicted blood loss will be estimated preoperatively by the operating surgeon based on a hemostatically normal individual of the same sex, age, stature and co-morbidities as the participant. The actual blood loss will be assessed consisting of the estimated blood loss, including into swabs, towels and suction during the procedure, per the anesthesiologist's record.

SECONDARY outcome
Timeframe: Day 0 (at completion of surgery)Population: Number of participants analyzed is 11, as for 3 participants the actual and the predicted blood loss was zero and for 1 participant the predicted blood loss was not collected. Therefore 'actual blood loss relative to predicted blood loss' could not be calculated. The full analysis data set was used for the analysis of this outcome measure.
Actual blood loss relative to predicted blood loss will be calculated as \[Actual Blood loss (mL)\] divided by \[Predicted Blood Loss (mL) multiplied by 100.

SECONDARY outcome
Timeframe: Day 0 (at completion of surgery)Population: Number of participants with major, minor and oral surgery and number of participant with Von Willebrand Type 1, 2A, 2B, 2M and 3 do sum up to the overall number of participants analyzed. The full analysis data set, including all participants who received investigational product and have at least 1 hemostatic assessment, was used for analysis.
Hemostatic efficacy will be rated on a scale of excellent - good - moderate - none. Excellent: Intraoperative blood loss was less than or equal to the maximum blood loss expected for the type of procedure performed in a hemostatically normal subject (≤ 100%). Good: Intraoperative blood loss was up to 50% more than the maximum expected blood loss for the type of procedure performed in a hemostatically normal subject (101-150%) Moderate: Intraoperative blood loss was more than 50% of the maximum expected blood loss for the type of procedure performed in a hemostatically normal subject (\>150%). None: Uncontrolled hemorrhage that was the result of inadequate therapeutic response despite proper dosing, necessitating a change of clotting factor replacement regimen.

Timeframe: PK measurements were done within 30 minutes pre-infusion, and post infusion at 30 (± 5) minutes, 60 (± 5) minutes, 6 (± 1) hours, 12 (± 1) hours, 24 (± 2) hours, 48 (± 2) hours and 72 (± 2) hours.Population: The PK analysis data set, including all participants who underwent PK assessment with data collected at the relevant time points, was used for analysis of this outcome measure.
This assessment is only required for subjects undergoing major surgery. Subjects will receive a PK infusion at a dose of 50±5 IU/kg rVWF:RCo within 42 days prior to surgery. The area under the plasma concentration/time curve from 0 to 72 hours post-infusion will be computed using the linear trapezoidal rule. For the calculation of AUC(0-72h) the levels at 72 hours will be linearly interpolated/extrapolated from the 2 nearest sampling time points. PK analysis was performed for the following analytes: VWF Ristocetin Cofactor Activity (VWF:RCo), VWF Antigen Activity (VWF:Ag), VWF Collagen Binding Activity (VWF:CB), VWF Activity Measured INNOVANCE VWF Ac Assay (VWF:Ac), FVIII Coagulation Activity (FVIII:C)

SECONDARY outcome
Timeframe: PK measurements were done within 30 minutes pre-infusion, and post infusion at 30 (± 5) minutes, 60 (± 5) minutes, 6 (± 1) hours, 12 (± 1) hours, 24 (± 2) hours, 48 (± 2) hours and 72 (± 2) hours.Population: The PK analysis data set, including all participants who underwent PK assessment with data collected at the relevant time points, was used for analysis of this outcome measure.
This assessment is only required for subjects undergoing major surgery. Subjects will receive a PK infusion at a dose of 50±5 IU/kg rVWF:RCo within 42 days prior to surgery. Vss will be calculated as the clearance multiplied with the mean residence time. PK analysis was performed for the following analytes: VWF Ristocetin Cofactor Activity (VWF:RCo), VWF Antigen Activity (VWF:Ag), VWF Collagen Binding Activity (VWF:CB), VWF Activity Measured INNOVANCE VWF Ac Assay (VWF:Ac)
