About this study

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

The aim of this study is to assess the pharmacokinetics (PK), efficacy, and safety of Biostate® in subjects with Von Willebrand Disease (VWD).

Pharmacokinetic Component:

Read more

PK parameters will be determined from a subgroup of subjects. Subjects who complete the PK component will subsequently continue in the efficacy component of the study, either continuing on a previously established prophylaxis regimen or continuing to receive on-demand treatment with the occurrence of non-surgical bleeding (NSB) events.

Efficacy Component:

Three treatment arms are defined for the efficacy component of the study. (1) Subjects who are currently being treated on a set prophylaxis regimen with a VWF product at the time of study entry will be enrolled in the "Prophylaxis" arm. (2) Subjects not being treated on a set prophylaxis regimen at the time of study entry who require a VWF product for the treatment of NSB events will be enrolled in the "On-demand" arm and commence using Biostate in the treatment of NSB events. (3) Subjects enrolled in the "On-demand" arm have the possibility to enter the "Cross-over to Prophylaxis" arm to receive an additional 12 months of prophylactic treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Biostate®Biological

    Also called Human Coagulation Factor VIII / von Willebrand Factor

    80 IU vWF/kg administered as a bolus intravenous infusion on Day 1 and approximately Day 180

  • Biostate®Biological

    Also called Human Coagulation Factor VIII / von Willebrand Factor

    Frequency and dose will be determined by the Investigator based on the subjects clinical condition, previous VWF concentrate requirements, response to therapy, weight and reason for usage.

What is being measured

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

  1. Haemostatic efficacy at time of non-surgical bleeding (NSB) event

    Measured: From Day 1 until final study visit

  2. Haemostatic efficacy overall

    Measured: Monthly (prophylactic therapy) or once every 3 months (for on-demand use)

  3. Number of treatments with blood product transfusions required to resolve any bleeding event

    Measured: From Day 1 until final study visit

  4. vWF/FVIII concentrate usage (number of infusions, IU/kg per dose, per event, per month and per year)

    Measured: From Day 1 until final study visit

  5. Assessment of blood loss during any surgical procedure

    Measured: From Day 1 until final study visit

  6. Number of spontaneous or traumatic NSB events

    Measured: From Day 1 until final study visit

  7. Pharmacokinetic parameters for vWF and FVIII (PK arm only)

    Measured: Up to 72 hours following infusions on Day 1 and approximately Day 180

Secondary outcomes (2)
  1. Development of FVIII inhibitors

    Measured: From Day 1 until final study visit

  2. Development of vWF inhibitors

    Measured: From Day 1 until final study visit

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Biostate® in people with Von Willebrand Disease, run by CSL Behring at 5 sites in 4 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 4 inclusion and 12 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 3 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Poland, Bulgaria, Russia, Ukraine. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 at time of non-surgical bleeding (NSB) event (time frame: From Day 1 until final study visit). The study lists 7 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 3 Oct 2017.
