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   43871   clinical trials with a EudraCT protocol, of which   7290   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.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Este estudio es para evaluar el uso de letrozol frente a anastrozol en el tratamiento adyuvante en pacientes de elevado riesgo. La población en estudio son mujeres posmenopáusicas que recientemente hayan sufrido su primera cirugía de cáncer de mama y con afectación ganglionar y receptores hormonales. La primera cirugía puede haber sido una mastectomia total, una mastectomia parcial o una cuadrantectomia de su cáncer de mama primario.

    • To compare the general safety between the two treatment arms.
    • To compare the two treatment groups in a descriptive manner with the other indicators of efficacy including overall survival, breast cancer specific survival, time to development of distant metastases and time to development of contra lateral breast cancer.

    • serum creatinine ≤ 2 times ULN.
    E.4Principal exclusion criteria
    • presence of metastatic disease.
    • concomitant or prior bilateral breast cancer.
    • previous or concomitant other (non-breast cancer) malignancy within the previous 5 years.
    • presence of other non-malignant systemic diseases which may prevent prolonged follow-up.
    • if no history of previous coronary heart disease but has at least two other coronary heart disease risk factors: LDL ≥160 mg/dL OR if fewer than two other coronary heart disease risk factors: LDL ≥190 mg/dL.
    • total fasting cholesterol ≥ 240 mg/dL.
    • patients on lipid-lowering agents, diet, or other measures for hyperlipidemia at baseline.
    • progressed on neoadjuvant endocrine therapy
