Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   41039   clinical trials with a EudraCT protocol, of which   6717   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    chart, will be used for statistical analysis purposes. The change from
    baseline in each eye will be the primary response of interest
    E.5.1.1Timepoint(s) of evaluation of this end point

    E.5.2Secondary end point(s)
    ETDRS visual acuity (quantitative score) over the follow-up period

    scores will be used for statistical analysis purposes.
    Response status to treatment at Week 48 and 96 after IVT injection.
    Responder will be defined by an improvement of at least 15 letters in the visual acuity score obtained with ETDRS or being greater than a Snellen acuity equivalent of 20/200.
    Measure of parameters of high resolution SD-OCT of the posterior
    pole and optic nerve at Week 48 and Week 96 .
