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.

    General information about the trial
    Main objective of the trial
    To evaluate efficacy and safety of Sunphenon EGCG in early stage Alzheimer´s disease. Primary outcome: delay of progression of early stage Alzheimer´s Disease (AD), defined by the deterioration in the ADAS-COG 18 months after treatment compared to baseline - in comparison to placebo. A modified version of ADAS-Cog with only 8 subtests was used. The categories linguistic expression, linguistic comprehension and word finding discorders were not scored. The category of orientation was replayced by the sub-category orientation of MMSE. A maximum score of 57 possible points on the ADAS-Cog was achievable in the study.
    Protection of trial subjects
    Every 3 months, the participants underwent a total of 6 clinical visits according to a standerized schedule. For each visit medical history, the physical and neurological status, vital sign, the basic laboratory panel and the occurence of adverse events were assessed. There were also four telephone visits record adverse events.

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    The aim was to recruit 2x25 subjectsand then to recalculate the number of cases. Due to organizational reasons (change of personnel and recruitment problems) only 21 patients were enrolled. This resulted in changes to study protocol.
