CCMO register: on and OMON

The public CCMO register contains both the core data and the results of research involving human subjects. Anyone can find which clinical studies in the Netherlands have been reviewed. This data is visible on and also in the Overview of Medical Research in the Netherlands (OMON) on

You can look in the CCMO register for study data by, for example, keyword, study number, research area or intervention and the type of condition. In ToetsingOnline you may find the study results under 'M. Sectie - Onderzoeksresultaten' in the overview of study data (the so-called ABR form). In OMON you may find the study result under ‘Results’. Not all results of clinical studies are disclosed. The sponsor may have objected to the disclosure, or the results may not have been disclosed as yet.
