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   43865   clinical trials with a EudraCT protocol, of which   7286   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 Objective of the trial
    E.2.1Main objective of the trial
    To demonstrate the benefit of sequential chemo-immunotherapy in increasing the number of patients reaching a pathological complete response (pCR) at radical surgery in patients with locally advanced irresectable (stage cT4NxM0) or clinically node-positive (stage cTxN1-N3M0) UC whose disease did not progress on or following completion of platinum-containing chemotherapy. The primary end point is the pCR rate, which is defined as the proportion of patients with absence of residual urothelial cancer cells (carcinoma in situ is allowed) in the surgical resection specimen, stage ypT0N0 / ypTisN0.
    Het voordeel aantonen van sequentiële chemo-immunotherapie bij het verhogen van het aantal patiënten dat een pathologische complete respons (pCR) bereikt bij radicale chirurgie bij patiënten met lokaal gevorderd irresectabel (stadium cT4NxM0) of klinisch klier-positief (stadium cTxN1-N3M0) UC bij wie de ziekte geen progressie vertoonde tijdens of na voltooiing van platinabevattende chemotherapie. Het primaire eindpunt is de pCR, die wordt gedefinieerd als het percentage patiënten met afwezigheid van resterende urotheelkankercellen (carcinoma in situ is toegestaan) in het chirurgische resectiemonster, stadium ypT0N0 / ypTisN0.

    - Safety and tolerability of preoperative avelumab as assessed by the CTCAE v5.0.
    - Clavien-Dindo surgical complications within 30 and 90 days from date of surgery.
    - The rate of non-invasive urothelial cancer in the surgical resection specimen, stage ypT0N0/ypTisN0/ypTaN0/ypT1N0.
    - The proportion of patients in whom radical surgery is delayed >8 weeks after day 14 of the last administration of avelumab due to immune-related toxicity.
    - De progressievrije, kankerspecifieke en algehele overleving na twee jaar, gedefinieerd als de tijd vanaf de eerste toediening van avelumab tot de follow-up van twee jaar is voltooid of tot: overlijden, kankerspecifiek overlijden, radiologische progressie zoals beoordeeld door kruis -sectionele beeldvorming, of afzien van of het annuleren van radicale chirurgie als gevolg van peri-operatieve irresectabele primaire tumor of aanwezigheid van gemetastaseerde ziekte.
    - Veiligheid en verdraagbaarheid van preoperatief avelumab zoals beoordeeld door de CTCAE v5.0.
    - Clavien-Dindo chirurgische complicaties binnen 30 en 90 dagen na de operatiedatum.
    - Het percentage niet-invasieve urotheelkanker in het chirurgische resectiemonster, stadium ypT0N0/ypTisN0/ypTaN0/ypT1N0.
    - Het percentage patiënten bij wie radicale chirurgie >8 weken na dag 14 van de laatste toediening van avelumab wordt uitgesteld vanwege immuungerelateerde toxiciteit.
