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   43857   clinical trials with a EudraCT protocol, of which   7284   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.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is the onset of a symptomatic venous thromboembolic event, during the hospitalization stay (and limited to D28 of hospitalization), as defined by a:
    - Symptomatic deep venous thrombosis, whatever the site and confirmed by a compression ultrasonography or an abnormal computed tomography angiogram with venous opacification
    or

    - Symptomatic pulmonary embolism, confirmed by:
    • a computed tomography angiogram,
    • or a V/Q scan,
    • or the presence, in a patient with a recent worsening dyspnea, of a deep venous thrombosis and/or a right ventricular dysfonction diagnosed by a transthoracic echocardiography in an unstable patients unable to benefit from a CT angiogram (2019 European Society of Cardiology Guidelines)
    or

    - Unexplained death when a pulmonary embolism cannot be excluded.

    The primary endpoint is a composite measure of clinical events and/or survival, as recommended by the WHO guidelines on COVID-19 Therapeutic Trial Synopsis (february, 2020).

    For each included patient, the onset of each event considered in the composite primary endpoint will be evaluated by a blinded independant endpoint adjudication committee.
    Le critère d’évaluation principal est la survenue d’un ETEV symptomatique, entre l’inclusion du patient et la fin de l’hospitalisation (28 jours maximum), défini par un événement parmi :

    - Thrombose veineuse profonde (TVP) symptomatique quel que soit le site veineux et confirmée par une échographie veineuse de compression ou un angioscanner (temps tardif) anormal
    ou

    - Embolie pulmonaire symptomatique, confirmée par :
    • un angioscanner thoracique spiralé,
    • ou une scintigraphie pulmonaire de ventilation/perfusion,
    • ou la présence, chez un patient présentant une dyspnée d’aggravation récente, d’une thrombose veineuse profonde et/ou d’une hypertension pulmonaire avec cœur pulmonaire aigu diagnostiquée à l’échocardiographie chez un patient pour lequel une imagerie en coupe est irréalisable (recommandations de l’European Society of Cardiology),
    ou

    - Décès inexpliqué pour lequel une EP ne peut être exclue.

    Il s’agit bien d’un critère composite associant différents paramètres cliniques et/ou la survie, tel que recommandé par l’OMS

    La survenue (ou non) chez chaque patient inclus des événements correspondant au critère d’évaluation principal sera revue à l’aveugle du bras de randomisation par un comité d’adjudication indépendant

    • a bleeding in a critical area or organ such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome, and/or
    • fatal bleeding.

    2d. The onset of a clinically-relevant non major bleeding as defined by the International Society on Thrombosis and Haemostasis as any sign or symptom of hemorrhage (e.g., more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for the ISTH definition of major bleeding but does meet at least one of the following criteria:
    • requiring medical intervention by a healthcare professional, and/or
    • needing a temporary cessation of the study treatment, and/or
    • causing discomfort for the patient such as pain.
    The clinically-relevant non major bleeding may be : macroscopic haematuria, gastrointestinal bleeding, hemoptysis, muscle hematoma, spontaneous subcutaneous hematoma > 25 cm2 or provoked subcutaneous hematoma > 100 cm2, multiple source bleeding, hematoma / bleeding from other site.

    • thrombosis of an extracorporeal membrane oxygenation (diagnosed by a dysfunction of the circuit)
    • deep vein thrombosis in other sites (eg. upper limb, splanchnic vein thrombosis, cerebral thrombophlebitis)
    These thromboses must be confirmed by a reference gold standard test according to most recent guidelines.

    3b. The onset of symptomatic arterial thrombosis, whatever the arterial site:
    • stroke, and/or
    • acute coronary syndrome, and/or

    These thromboses must be confirmed by a reference gold standard test according to most recent guidelines.

    4. All-cause mortality.

    5. Same outcome as the primary outcome

    6. Variables associated with the occurrence of venous thromboembolism that will be recorded are: age, gender, cardiovascular risk factors, past medical history, treatments, clinical characteristics, laboratory parameters recorded during patient management.

    The occurrence (or not) of the secondary outcomes in each included patient will be reviewed blindly of the randomization arm by an independent adjudication committee.
