New Dutch Trial Register online
The website of the new Dutch Trial Register (‘Landelijk Trial Register’; LTR) is available. The ultimate aim of the LTR is to provide a clear overview of all clinical research in the Netherlands in one register. Currently, the LTR only contains the data from the former National Trial Register (NTR). Gradually, the LTR will be expanded with data from other registers.
Data in the LTR
The LTR currently includes only the studies registered in the old National Trial Register (NTR). All data have been imported unchanged into the new register and cannot be modified. Functionalities are being built in so that this will eventually be possible. If you need to make changes in a specific study now, please consult the LTR website.
New registration
It is currently not possible as yet to register new research in LTR. To register a new study, you can choose one of the approved WHO registries such as ClinicalTrials.gov. The full list of approved registries can be found at Primary registries in the WHO registry network.
LTR in the future
The LTR will import all data from ToetsingOnline in addition to all data from the NTR. Next year, studies from CTIS will also be added. Also, it will eventually be possible to register new research in the LTR, both studies subject to the Dutch WMO (Medical Research involving Human Subjects Act) and non-WMO studies. In future, studies from Eudamed will be added as well. Once the LTR is fully realised, CCMO will apply for WHO-approval of the register. Changes in the LTR will be reported on the LTR website.
