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   42880   clinical trials with a EudraCT protocol, of which   7063   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) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.5 End points
    E.5.1Primary end point(s)
    Overall incidence of adverse events will be evaluated for each dose level (9xE09 vg, 3xE10 vg or 9xE10 vg), and for the study as a whole. Similarly, the incidence of serious adverse events will be monitored. An interim complete safety analysis will be performed at 24 weeks of follow-up after the injection of the last subject of the 4rd cohort. In addition, a full analysis will be done 48 weeks after the injection of the last included subject.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Interim analysis = 24 weeks
    Full analysis = 48 weeks
    E.5.2Secondary end point(s)
    Efficacy by measuring the central visual function as assessed by the visual acuity and visual field 48 weeks after the injection (ETDRS scale, vision test, Computerized visual field)
    Efficacy on visual criteria overtime, relative to baseline measured by:
    - Computerized visual field (Humphrey 24.2) to measure visual field (threshold and mean deviation)
    - Computerized visual field (Octopus) to measure central scotoma
    - Fundus perimetry measured with micro perimeter
    - Optical Coherence Tomography (OCT) to measure 360° and each quadrant thickness of peripapillary retinal nerve fiber layer (RNFL)
    - Visual evoked potential (VEP) to measure latency and amplitude
    - Pattern Electroretinogram (PERG) to measure peak time and amplitude
    - Color vision measured by Computer graphic method
    Evaluation of the eye fundus by OCT and fundus imaging overtime, relative to baseline
    Cellular and humoral (total and/or neutralizing antibodies) response to AAV2 will be measured
    E.5.2.1Timepoint(s) of evaluation of this end point
    Secondary endpoints will be assessed 48 weeks after the injection of GS010.
