Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    The main objective of this study was to prospectively evaluate the annualised bleeding rate (ABR) for spontaneous bleeding episodes while on prophylactic treatment with recombinant von Willebrand factor (rVWF) and to compare it to the subject’s historical ABR for spontaneous bleeding episodes.
    Protection of trial subjects
    The study was conducted in accordance with the ethical principles that have their origins in the Declaration of Helsinki and in compliance with all applicable industry regulations, International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) Guideline E6 (1996), European Union (EU) Directive 2001/20/EC, as well as all applicable national and local laws and regulations.

    Arm description
    Subjects who had taken only on-demand von Willebrand factor (VWF) prior to the current study received rVWF (vonicog alpha) initial prophylactic treatment at a dose range of 50 plus minus (+/- ) 10 international unit per kilogram (IU/kg), intravenous infusion, twice per week for a planned period of 12 months. Dose escalation to higher dose (up to 80 IU/kg per infusion) or frequency (up to 3 times a week) was based on medical indication and investigator judgment. During this prophylactic treatment period, any breakthrough bleeding episodes requiring replacement therapy with VWF concentrate was treated with rVWF with or without ADVATE (recombinant Factor VIII [rFVIII]); the dose was determined according to the bleeding type and severity, and was adjusted based on the subject’s clinical response.

    Ratio of Annualized Bleeding Rate (ABR) (On-study ABR / Historical ABR) for Spontaneous Bleeding Episodes (BEs) Assessed by Investigator During Prophylactic Treatment With rVWF Through Month 12 [1]
    End point description
    ABR for treated spontaneous BEs while on prophylactic treatment with rVWF through Month 12 treatment period/observation period (in years), where an observation period = (date of completion/termination – date of first dose + 1)/365.2425. BEs occurred at the same anatomical location with the same etiology within 24 hours after onset of first bleed were considered single BE. BEs occurred at multiple locations related to same injury were considered as single BE. Observation period for historical BEs was 365 days prior to first dose of study drug. On-study observation period started from first administration of study drug and continuing through the date of completion/discontinuation from study. The comparison of the two ABRs (on-study and historical) for spontaneous BEs (not related to trauma) during prophylactic treatment with rVWF was reported as a ratio of mean ABRs (on-study ABR/historical ABR). Full analysis set (FAS) composed of all subjects who received prophylactic IP treatment.

    The sABR was the number of spontaneous bleeds divided by the observation period in years, where an observation period = (date of completion/termination–date of first dose+1)/365.2425.sABR was categorized based on number of BEs as 0, greater than (>) 0 through 2,>2 through 5,>5 during the prophylactic treatment with rVWF (vonicog alfa) through 12 months. Bleeding at multiple locations related to the same injury was counted as single bleeding episode. BEs of unknown cause were counted as spontaneous bleeds. Observation period for historical BEs was 365 days prior to first dose of study drug. The baseline sABR for treated BEs was based on historical BE data and on-study sABR was based on treated spontaneous BEs during prophylaxis with rVWF through Month 12. On-study observation period started on the day of first administration of study drug continuing through the date of completion/discontinuation from study. Number of participants based on categorized sABR was calculated and reported.

    End point description
    An AE is defined as any untoward medical occurrence in a subject administered IP that does not necessarily have a causal relationship with the treatment. TEAEs were events which occurred on or after the date and time of administration of the first dose of study medication. TEAEs included both serious AEs and non-serious AEs. Severity of TEAEs was determined by following definitions: Mild: No limitation of usual activities; Moderate: Some limitation of usual activities and may required therapeutic intervention; Severe: Inability to carry out usual activities with sequelae, which required therapeutic intervention. Subjects were counted by considering the maximum severity of TEAEs. SAS composed of all subjects who received any amount of IP (rVWF, vonicog alpha).

    An AE was defined as any untoward medical occurrence in a subject administered IP that does not necessarily have a causal relationship with the treatment. TEAEs were events which occurred on or after the date and time of administration of the first dose of study medication. TEAEs included both serious AEs and non-serious AEs. For each AE, the investigator assessed the causal relationship between the IP and the AE based on clinical expertise and judgment according to the following circumstances of the AE: Not related, Unlikely related, Possibly related, or Probably related. A related TEAE was defined as any TEAE indicated as 'possibly related' or 'probably related'. Number of subjects with TEAEs based causality was reported.

    Switch Subjects
    Reporting group description
    Subjects who had taken prophylactic treatment with pdVWF prior to current study and switched to rVWF (vonicog alpha); received rVWF at an initial prophylactic dose of +/- 10 % of weekly pdVWF dose received prior to this study. Dose escalation to higher dose (up to 80 IU/kg per infusion) or frequency (up to 3 times a week or once a week depending on the total weekly dose and the dosing regimen used in their previous pdVWF prophylaxis regimen) was based on medical indication and investigator judgment. During this prophylaxis treatment period, any bleeding episodes requiring replacement therapy with VWF concentrate was treated with rVWF with or without rFVIII (ADVATE); the dose was determined according to the bleeding type and severity, and was adjusted based on the subject’s clinical response.

    Reporting group title
    On-Demand Subjects
    Reporting group description
    Subjects who had taken only on-demand VWF prior to the current study received rVWF (vonicog alpha) initial prophylactic treatment at a dose range of 50 +/- 10 IU/kg, intravenous infusion, twice per week for up to 12 months. Dose was escalated up to 80 IU/kg infusion, dosing frequency up to 3 times a week based on medical indication and investigator judgement. During this prophylaxis treatment period, any bleeding episodes requiring substitution therapy with VWF concentrate was treated with rVWF with or without rFVIII (ADVATE); the dose was determined according to the bleeding type and severity, and was adjusted based on the subject's clinical response.
