About this study

Official title: An Open-label, Multi-centre Post-marketing Study to Assess the Efficacy and Safety of Voncento® in Subjects With Von Willebrand Disease

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.

Receives: Biological: Voncento

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Assessed daily by the subject until the bleed stops, for the duration of the subject's participation in the study (approximately 12 months). Each bleeding event is also to be assessed retrospectively by the Investigator.

  2. Number of infusions - NSB event

    Number of infusions of Voncento required to treat an NSB event.

    Measured: For the duration of the subject's participation in the study (approximately 12 months).

  3. 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.

    Measured: For the duration of the subject's participation in the study (approximately 12 months).

  4. Number of NSB events per month

    Measured: From Day 1 until final study visit, approximately 12 months.

  5. Annual bleeding rate

    The number of bleeding events per year

    Measured: For the duration of the subject's participation in the study (approximately 12 months).

Secondary outcomes (7)
  1. Assessment of blood loss during a surgical procedure

    Measured: During surgery, for any surgical procedure during the subject's participation in the study (approximately 12 months).

  2. 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.

    Measured: Assessed during and after surgery until the bleeding stops, for any surgical procedure during the subject's participation in the study (approximately 12 months).

  3. Number of infusions - surgical bleeding event

    Number of infusions of Voncento required to treat a surgical bleeding event.

    Measured: For the duration of the subject's participation in the study (approximately 12 months).

  4. 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.

    Measured: For the duration of the subject's participation in the study (approximately 12 months).

  5. Overall adverse events

    Overall number of subjects with: adverse events (AEs), serious AEs, AEs related to Voncento administration, and adverse events of special interest.

    Measured: From Day 1 until the final study visit for each subject (approximately 12 months)

  6. Number of subjects with VWF or FVIII inhibitors

    Measured: At screening, Day 1 and approximately Months 3, 6, 9 and 12, for each subject.

  7. 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.

    Measured: Approximately every month (subject assessment) and every 3 months (Investigator assessment) for the duration of the subject's participation in the study (approximately 12 months).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Voncento in people with Von Willebrand Disease, run by CSL Behring at 12 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United Kingdom, Poland, Germany, Austria, Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Haemostatic efficacy - NSB event (time frame: Assessed daily by the subject until the bleed stops, for the duration of the subject's participation in the study (approximately 12 months). Each bleeding event is also to be assessed retrospectively by the Investigator.). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2018.
