The public part of the DRKS-register is freely accessible to all interested users. You can use the function "study search" to search for clinical studies that have already been registered.
The "Search term" field allows you to search for one or more words. The following fields are searched and the studies found are displayed sorted by relevance:

• Title of the study
• Brief summary in scientific language
• Brief summary in lay language
• DRKS ID

You can narrow the search down using further search filters from the areas "General", "Recruitment" or "Study design". You can select search filters individually or in combination.

Please note that studies conducted in Germany may also be listed in other registries. You can find more information in the FAQ - In which other registries are studies conducted in Germany registered?
