The Dutch Trial Register (LTR) shows the studies that were registered in the former National Trial Register (NTR). All data as registered in the NTR have been added unaltered. If you want to adjust your data, you can use the guidelines set out below.
What to do with ongoing studies already registered in the NTR?
You can modify your study data by completing the form ‘Wijziging NTR registratie’ (in Dutch). You will receive a confirmation once this has been implemented.
The data as registered in NTR are automatically included in the International Clinical Trial Registry Platform (ICTRP) and can be consulted on ICTRP Search Portal. Thus, the investigator still fulfils the requirement of prospective registration as required by the International Committee of Medical Journal Editors (ICMJE) for publication in scientific journals. Modifications are also included automatically in the ICTRP.
What to do when registering new studies?
For the registration of new studies you may choose one of the WHO-approved registries, for example ClinicalTrials.gov. The full list of approved registries can be found at Primary registries in the WHO registry network.
In addition to studies from the former NTR, the Dutch Trial Register will eventually replace ToetsingOnline. Hereafter, studies from CTIS and Eudamed will be added to the register. In the long run it will also be possible to register new studies in the Dutch Trial Register. This will include both WMO as well as non-WMO studies.
