From May 15th, 2023 it will be possible to change data of studies previously registered in the National Trial Register (NTR). These data were transferred to the Dutch Trial Register (Landelijk Trial Register; LTR) at the end of 2022. For more information see our previous news item about the Dutch Trial Register.

You can modify your study data by completing the form ‘Wijziging NTR registratie’ (in Dutch). The CCMO will then process your modifications. You will receive a confirmation once this has been implemented.

For more information see the website of the CCMO.
