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.

    General information about the trial
    Main objective of the trial
    To estimate the efficacy of induction chemotherapy followed by chemoradiotherapy, or the other way round, before surgery in patients with locally advanced rectal cancer. As primary endpoint, the rate of patients with pathological complete remissions (pCR) will be compared exploratively between the treatment arms and to expectations derived from historical data.
    Protection of trial subjects
    A Data Safety and Monitoring Board with at least three members will be established, consisting of experts in medical, surgical or radiotherapeutic oncology specializing in rectal cancer, and a statistical expert. The DSMB will receive regular information on safety results of the trial, namely a list of reported SAEs/SUSARs.

Surgery should be performed about 6 weeks later, i.e. around day 123.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 311 patients were randomized but 5 patients were excluded because of constent withdrawel or protocol entry violation. All further analyses were performed within the 306 patients. [https://doi.org/10.1200/JCO.19.00308]
