Netherlands Trial Register (NTR) No Longer Available
As per an update posted on Central Committee on Research Involving Human Subjects (CCMO) website on June 24, 2022, the NTR is no longer available. The National Trial Register, in which the CCMO register and the NTR will be merged, is not yet ready for use.
Guidelines provided to researchers for the time being are as below:
- For ongoing investigations that were already reported to the NTR: The data as registered in NTR are automatically included in the International Clinical Trial Registry Platform (ICTRP) and can be consulted on the ICTRP Search Portal. The researcher thus still meets the requirement of prospective registration as required by the International Committee of Medical Journal Editors (ICMJE) for publication in scientific journals. Unfortunately, the data can no longer be edited. If adjustment of the data is nevertheless necessary, the research will have to be registered again with another recognized register, see below. A reference to the trail ID of NTR must be included.
- For registering new trials: New studies can be registered on any WHO recognized registers, such as ClinicalTrials.gov. The full list of recognized registries can be found at Primary registries in the WHO registry network.
As soon as this situation changes, the CCMO will inform researchers. Click here for more information.
