Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Voncento

Arm Description

The frequency and dose of Voncento administration will be determined by the investigator using the information included in the Voncento Summary of product characteristics (SmPC)

Outcomes

Primary Outcome Measures

Haemostatic efficacy - NSB event
Subject's and investigator's assessment of haemostatic efficacy of Voncento in its usage for a non-surgical bleeding (NSB) event. Assessments of haemostatic efficacy will be based on a 4-point ordinal scale of Excellent, Good, Moderate or None.
Number of infusions - NSB event
Number of infusions of Voncento required to treat an NSB event.
Total dose of Voncento - NSB event
Total dose of Voncento (in international units of Von Willebrand Factor: Ristocetin Cofactor) required to treat an NSB event.
Number of NSB events per month
Annual bleeding rate
The number of bleeding events per year

Secondary Outcome Measures

Assessment of blood loss during a surgical procedure
Haemostatic efficacy - surgical event
Investigator's or surgeon's assessment of haemostatic efficacy of Voncento in its usage for a surgical bleeding event. Assessments of haemostatic efficacy will be based on a 4-point ordinal scale of Excellent, Good, Moderate or None.
Number of infusions - surgical bleeding event
Number of infusions of Voncento required to treat a surgical bleeding event.
Total dose of Voncento - surgical bleeding event
Total dose of Voncento (in international units of Von Willebrand Factor: Ristocetin Cofactor) required to treat a surgical bleeding event.
Overall adverse events
Overall number of subjects with: adverse events (AEs), serious AEs, AEs related to Voncento administration, and adverse events of special interest.
Number of subjects with VWF or FVIII inhibitors
Haemostatic efficacy - prophylaxis
Subject's and investigator's assessment of haemostatic efficacy of Voncento as prophylaxis therapy. Assessments of haemostatic efficacy will be based on a grading scale with outcomes of excellent, good, moderate, none.

5. Study Description

Brief Summary
This is a multi-centre, open-label, single-arm, phase 4, post-marketing study to further investigate the efficacy and safety of Voncento in subjects with Von Willebrand Disease (VWD) in whom treatment with a Von Willebrand Factor (VWF) product is required as on-demand therapy, for prophylactic therapy, or during surgery. Subjects will be treated with Voncento either as an on-demand regimen (eg, to treat a non-surgical spontaneous or traumatic bleeding event) or prevention regimen (eg, to prevent an anticipated bleeding event) at a dose prescribed by the Investigator in accordance with the Voncento Summary of Product Characteristics (SmPC), or with a prophylaxis regimen (regular treatment with Voncento at a frequency of 1-3 times per week). Voncento will also be given to prevent and treat any surgical bleeding events.
