CTIS for sponsors

The sponsor workspace in the Clinical Trials Information System (CTIS) assists clinical trial sponsors and other organisations involved in running clinical trials in preparing and compiling clinical trial applications and dossiers to submit for assessment by Member States in the European Union (EU) and European Economic Area (EEA).

The revised CTIS transparency rules will become applicable on 18 June 2024, with the launch of a new version of the CTIS website. Support materials and more information are available under Transparency: Questions and Answers.
