About Dutch Trial Register
The site provides the Overview of Medical Research in the Netherlands (OMON), where visitors can search for medical research involving human participants. Professionals can register, submit and manage studies through the Research Portal.
OMON includes records from the former National Trial Register (NTR), ToetsingOnline, the Research Portal and the public portal of CTIS. Former NTR information is available in English only, other information is generally in Dutch and English, and details such as recruitment status may be outdated, so users are asked to confirm current status with the submitting party.
