About this study

Official title: A Phase II, Multicentre, Double-blinded, Randomised, Cross-over Study to Evaluate Efficacy, Safety and Pharmacokinetics of Biostate® in Subjects With Haemophilia A.

The aim of this study are to

  • assess the efficacy of Biostate® [Study Product (SP)] in subjects with Haemophilia A
  • compare the pharmacokinetics of Biostate® [SP] with the previously marketed product Biostate® (here referred to as Biostate® [Reference Product (RP)]).

This study is divided into 3 parts:

Part 1: Cross-over pharmacokinetic (PK) component. PK subjects will be randomised to determine the order in which they receive the two study products. This part of the study is double-blinded.

Part 2: Efficacy component. All subjects will receive Biostate® [SP] as required to manage their haemophilia condition for an estimated period of 6 months (or minimum of 50 exposure days) to assess efficacy and safety of the product. This part of the study is open-label.

Part 3: Repeat pharmacokinetic assessment. Subjects who participated in Part 1 (PK component) will undergo a repeat PK assessment on Day 180 following administration of Biostate® [SP].

What participants receive

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

  • Biostate® [SP]Biological

    Also called Human Coagulation Factor VIII / von Willebrand Factor

    Single bolus intravenous dose of 50 IU/kg

  • Biostate® [SP]Biological

    Also called Human Coagulation Factor VIII / von Willebrand Factor

    The dose is dependent on the reason for use and may consist of repeated bolus doses as required to manage haemophilia condition.

  • Biostate® [RP]Biological

    Also called Biostate®, Human Coagulation Factor VIII / von Willebrand Factor

    Single bolus intravenous dose of 50 IU/kg.

What is being measured

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

  1. Haemostatic efficacy

    Measured: Monthly, until final study visit

  2. Number of treatments/units required to resolve any bleeding event

    Measured: From Day 1 until final study visit

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

    Measured: From Day 1 until final study visit

  4. Assessment of blood loss during any surgical procedure

    Measured: From Day 1 until final study visit

  5. Pharmacokinetics of FVIII activity

    Measured: Up to 48 hours following infusions (Part 1 and Part 3 only)

Secondary outcomes (2)
  1. The nature, frequency and incidence of adverse events

    Measured: From Day 1 until final study visit

  2. Development of FVIII inhibitors

    Measured: From Day 1 until final study visit

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Biostate® [SP] and Biostate® [RP] in people with Hemophilia A, run by CSL Behring at 14 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 7 inclusion and 11 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 11 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Poland, Bulgaria, Russia, North Macedonia. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 (time frame: Monthly, until final study visit). 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 11 Feb 2011.
