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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    To prospectively evaluate the efficacy of rVWF prophylaxis in children based on the annualized bleeding rate (ABR) with intra-patient control (on-study compared to historical) for all bleeding episodes classified by the investigator as either spontaneous or traumatic while on prophylactic treatment with rVWF.
    Evaluar de forma prospectiva la eficacia de la profilaxis con rVWF en niños en función de la tasa anual de hemorragias (TAH) con control intrapaciente (en el estudio en comparación con el histórico) en todos los episodios hemorrágicos clasificados por el investigador como espontáneos o traumáticos durante el tratamiento profiláctico con rVWF.
    E.2.2Secondary objectives of the trial
    * To evaluate the long-term safety of rVWF as assessed by adverse events (AEs), including thrombogenicity, hypersensitivity, and immunogenicity, as well as by vital signs and clinical laboratory parameters
    * To evaluate additional efficacy of prophylactic treatment with rVWF
    * To assess the efficacy of rVWF for On Demand (OD) treatment of breakthrough bleeding episodes (spontaneous and traumatic) while on prophylactic treatment
    * To assess pharmacokinetics (PK) and pharmacodynamics (PD) of rVWF following long-term prophylactic treatment
    * Evaluar la seguridad a largo plazo de rVWF según la evaluación de los acontecimientos adversos (AA), incluidas la trombogenia, la hipersensibilidad y la inmunogenia, así como de las constantes vitales y los parámetros analíticos.
    * Evaluar la eficacia adicional del tratamiento profiláctico con rVWF.
    * Evaluar la eficacia de rVWF para el tratamiento a demanda de los episodios hemorrágicos intercurrentes (espontáneos y traumáticos) durante el tratamiento profiláctico.
    * Evaluar la farmacocinética (FC) y la farmacodinámica (FD) de rVWF después del tratamiento profiláctico a largo plazo.

    1. The subject has a documented diagnosis of severe VWD (baseline VWF:RCo <20 IU/dL) with a history of substitution therapy with VWF concentrate required to control bleeding and a diagnosis of VWD type 1, type 2 (2A, 2B, 2M, 2N), or type 3.
    Diagnosis is confirmed, as applicable, by genetic testing and/or by multimer analysis, which may be documented in patient’s history or tested at screening.
    2. The subject is <18 years of age at the time of screening.
    3. Prescreening treatment requirements:
    a. The subject has been receiving On Demand (OD) therapy with VWF products for at least 12 months (for subjects ≥2 years of age) prior to screening, has experienced at least 1 VWF-treated bleeding event (excluding menorrhagia/heavy menstrual bleeding, as applicable) in the last 12 months, and prophylactic treatment is recommended by the investigator (Prior OD subjects); or
    b. The subject has been receiving prophylactic treatment with plasma-derived (pd)VWF products for at least 12 months prior to screening (for subjects ≥2 years of age) and switching to prophylaxis with rVWF is recommended by the investigator (Switch subjects),
    c. For subjects <2 years of age, the required duration for prior OD therapy with VWF products or for prior prophylactic treatment with pdVWF products is at least 6 months. Prior OD subjects <2 years of age should have experienced at least 1 VWF-treated bleeding event during the last 6 months based on medical records and be recommended to receive prophylactic treatment by the investigator.
    4. For subjects ≥2 years of age, the subject has available records that reliably evaluate type, frequency, severity, and treatment of bleeding episodes for at least 12 months preceding enrollment. For subjects <2 years of age, the subject has available records that reliably evaluate type, frequency, severity and treatment of bleeding episodes for at least 6 months preceding enrollment.
    5. If ≥12 years old at the time of screening, the subject has a body mass index (BMI) ≥15 but <40 kg/m2. If ≥2 to <12 years old at the time of screening, the subject has a BMI of ≥5th and <95th percentile (per Centers for Disease Control and Prevention [CDC] clinical charts). For younger subjects who are <2 years old, the “weight-for-age” clinical charts (5th to 95th percentile) provided by the CDC should be utilized to ensure the subject has a body weight of ≥5th and <95th percentiles based on gender (for clinical charts provided by CDC, refer to: https://www.cdc.gov/growthcharts/clinical_charts.htm).
    6. Female subjects of childbearing potential (ie, had onset of menses/reached puberty) must have a negative blood/urine pregnancy test result at screening and agree to employ highly effective birth control measures (as defined in the protocol) for the duration of their participation in the study.
    7. The subject has voluntarily provided assent (if appropriate) and the legally authorized representative(s) has provided informed consent.
    8. The subject and/or legally authorized representative is willing and able to comply with the requirements of the protocol, which should also be confirmed based on a prescreening evaluation held between the investigator and the sponsor to ensure no eminent risk is present that could challenge the subject’s compliance with the study requirements.

    El diagnóstico se ha confirmado, según corresponda, mediante pruebas genéticas o mediante análisis de multímeros, que pueden estar documentados en los antecedentes del paciente o haberse realizado en la selección.
    2. El participante tiene <18 años en el momento de la selección.
    3. Requisitos del tratamiento previos a la selección:
    a. El participante ha estado recibiendo tratamiento a demanda con productos FVW durante al menos 12 meses (para los participantes ≥2 años) antes de la selección, ha presentado al menos 1 acontecimiento hemorrágico tratado con FVW (a excepción de la menorragia/menstruación profusa, según proceda) en los últimos 12 meses y el investigador recomienda tratamiento profiláctico (participantes con tratamiento a demanda previo); o
    b. El participante ha estado recibiendo tratamiento profiláctico con productos FVW derivados del plasma (pd) durante al menos 12 meses antes de la selección (para participantes ≥2 años) y el investigador recomienda el cambio a profilaxis con rVWF (participantes con cambio).
    c. En el caso de los participantes <2 años, la duración obligatoria del tratamiento a demanda previo con productos FVW o del tratamiento profiláctico previo con productos FVWpd es de al menos 6 meses. Los participantes <2 años con tratamiento a demanda previo deben haber tenido al menos 1 acontecimiento hemorrágico tratado con FVW durante los últimos 6 meses según la historia clínica y el investigador debe haberles recomendado recibir tratamiento profiláctico.
