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   43931   clinical trials with a EudraCT protocol, of which   7307   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.

    End point title
    Changes in SUV
    End point description
    Percentaged changes (proposed reductions) in the SUVs of PET images after one week of therapy as compared with the baseline assessment were compared with the response outcome (i. e., PD vs non-PD) in the first restaging procedure after six weeks of com-bined therapy. The related changes were analyzed using a responder-operator-characteristics (ROC) curve and the corresponding area under the curve (AUC). The maximal Youden-indices found in these analyses were then taken as cut-off values for Kaplan Meier analyses regarding PFS. Further, we tested predefined cut-off values (20%, 30% reductions in PET activities) regarding their potential role in discriminating patients with benefit from therapy as seen in prolonged PFS.

    Sample size calculation
    Statistical analysis description
    Assumptions: (1) 20% responder, 40% progressers; thus 60% non-progressers (2) Primary variable is the ‘area under the ROC curve (AUC, )’ (3) Type-I-error 0.043; type-II-error 0.20 (4) True accuracy (AUC) is at least 0.70 (alternative hypothesis; some common diagnostic tests have an AUC greater than 0.70) The sample size in the following table was calculated using formulae (6.3) and (6.6) in [118]. Thus, assuming Sigma1 = 0.75, about 40 patients are needed to reject the null hypothesis.
