Enter one or several search terms directly into the search box and filter the search according to different criteria. A full-text search is carried out across all clinical trials registered in the federal and the WHO databases.
Where does the trial information come from?
The data are entered by the respective researchers themselves. The researchers are solely responsible for data accuracy. A search enquiry will produce, on the one hand, data that are registered in a World Health Organization (WHO)-approved primary register for clinical trials and, on the other hand, the data – on the same trial – as entered in the supplementary federal database (the SNCTP). The federal database contains additional data that apply specifically to Switzerland and provide information about the trial in a layperson’s language.
My search request only produced a few hits or none at all. What can I do?
Try varying the search term, for example, by entering the technical term instead of the lay term or by entering the English equivalent of the term you are searching for. Use of an English search term for a trial is most likely to produce a result, as the standard entries of trials in a WHO primary register are in English. In the supplementary federal database, trial data are recorded by the researchers in German, French or Italian.
My search request produced a large number of hits. What can I do?
You can reduce the number of search results by restricting your search to a specific recruitment status or age group. To do this, choose the appropriate criteria.
