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   44334   clinical trials with a EudraCT protocol, of which   7366   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Adverse event(AE)=any untoward medical occurrence in clinical investigation participant administered drug;it does not necessarily have to have causal relationship with this treatment. AE can therefore be any unfavorable&unintended sign (example,clinically significant abnormal laboratory value),symptom/disease temporally associated with use of drug whether/not it is considered related to drug. TEAE=any event emerging/manifesting at or after initiation of investigational product or any existing event that worsens in either intensity or frequency following exposure to investigational product. SAE=any untoward clinical manifestation of signs, symptoms/outcomes(whether considered related to investigational product or not)&at any dose: results in death,is life-threatening,requires in-patient hospitalization/prolongation of hospitalization,results in persistent/significant disability/incapacity,results in congenital abnormality/birth defect,or is an important medical event.

    An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory value), symptom, or disease temporally associated with the use of a drug whether or not it is considered related to the drug. A TEAE is defined as any event emerging or manifesting at or after the initiation of the investigational product or any existing event that worsens in either intensity or frequency following exposure to the investigational product. The Safety Set (SAF) included all participants in the ITT Set who received at least 1 dose of VPRIV.

    SF-36 Version 2 is a multipurpose, participant completed, short-form health survey with 36 questions that consists of an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures. Physical component summary (PCS) is mostly contributed by physical function (PF), role physical (RP), bodily pain (BP), and general health (GH). Mental component summary (MCS) is mostly contributed by mental health (MH), role emotional (RE), social function (SF), and vitality (VT). Each component on the SF-36 item health survey is scored from 0 (best) to 100 (worst). Total score ranges from 0-100 for each component summary (i.e., PCS and MCS), where higher scores are associated with less disability and better quality of life. The SAF included all participants in the ITT Set who received at least 1 dose of VPRIV. Subjects analysed is the number of participants with data available for analyses.

    The CHQ-PF-50 is a 50-item questionnaire to be completed by the parents or guardians of children between 5 and 18 years of age. The 50 questions measure 14 domains (global health, physical functioning, role/social limitations (emotional/behavioral and physical), bodily pain/discomfort, behavior, global behavior, mental health, self-esteem, general health perceptions, change in health, parental impact (emotional and time), family activities, and family cohesion) which were summarized as the physical and psychological summary scores. Each summary score was transformed and could range from 0 to 100, with higher score indicating better physical and psychosocial health. A positive change from Baseline indicates improved well-being. The SAF included all participants in the ITT Set who received at least 1 dose of VPRIV. Subjects analysed is the number of participants with data available for analyses.

    Date
    Amendment
    02 Aug 2022
    The following changes were made as per Amendment 01: 1. Increased the frequency of the body weight test as body weight changes requires to recalculate the dose of investigational product. 2. Increased the number of clinical sites from ‘5 to 6’ to ‘at least 8’ to increase the recruitment capability. 3. Updated the previous inclusion criteria.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
