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.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Age ≥18 years (except in regions in which the minimum age for subject participation is >18 years).

    Patients with HER2-overexpressing advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma that has progressed on or after a prior HER2-directed agent and fluoropyrimidine- or platinum-containing chemotherapy (2nd-line or 3rd-line). HER2 overexpression (in a tissue sample taken after the patient’s most recent HER2-directed therapy) is determined by HER2 protein overexpression and/or HER2 gene amplification in tumor specimens assessed with FDA-approved (and local regulatory authority-approved) tests specific for gastric cancer. (HER2 positivity will be centrally assessed for eligibility in Phase 3.)


    Patients must have at least one measurable lesion as defined by RECIST version 1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.

    Adequate bone marrow, renal, liver, cardiac (via ECG), clotting (INR/PT and PTT) function.

    Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) must be 0 or 1.

    Resolved acute effects of any prior therapy.

    Patients of childbearing potential must be non-pregnant and must agree to use a highly effective method of contraception throughout the study.

    Consent to the study and study procedures.
    La edad debe ser ≥18 años (excepto en regiones en las que la edad mínima para participar en el estudio es >18 años).

    Pacientes con adenocarcinoma gástrico o de la unión gastroesofágica (UGE) avanzado o metastásico con sobreexpresión de HER2 que ha progresado durante o después de un tratamiento previo con un agente dirigido a HER2 y una quimioterapia basada en fluoropirimidinas o un derivado del platino (de segunda o tercera línea). La sobreexpresión de HER2 (en una muestra de tejido tomada después del tratamiento dirigido a HER2 más reciente del paciente) se determina mediante la sobreexpresión de la proteína HER2 o la amplificación del gen HER2 en muestras tumorales evaluadas con pruebas específicas para el cáncer gástrico aprobadas por la FDA (y por las autoridades reguladoras locales). (Se evaluará de forma centralizada la positividad de HER2 para la elegibilidad en la fase 3).

    Los pacientes deben tener al menos una lesión neoplásica medible según los criterios definidos por el método RECIST versión 1.1. Las lesiones situadas en una zona previamente irradiada se consideran medibles si se ha demostrado la progresión en dichas lesiones.

    Actividad adecuada de médula ósea, renal, hepática, cardíaca (mediante ECG), de coagulación (INR/TP y TTP).

    Estado funcional del Grupo Oncológico Cooperativo de la Costa Este (Eastern Cooperative Oncology Group, ECOG) de los EE. UU. de 0 o 1.

    Efectos agudos resueltos de cualquier tratamiento previo.

    Las pacientes con capacidad de concebir no deben estar embarazadas y deben aceptar el uso de un método anticonceptivo altamente eficaz a lo largo del estudio.

    Consentimiento para el estudio y los procedimientos del estudio.
