Information on Clinical Trials in the European Union and European Economic Area

The website provides limited information on individual clinical trials in the European Union (EU) and European Economic Area (EEA), with plans to gradually include more data as clinical trial sponsors and regulators use it post the launch on 31 January 2022. However, clinical trials with decisions issued after mid-August 2022 that involve deferrals are not currently published on the Clinical Trials Information System (CTIS) as a temporary measure until the full restoration of the public portal functionalities.

For detailed information regarding clinical trials initiated before 31 January 2022, individuals can refer to the European Union Clinical Trials Register. The CTIS allows clinical trial sponsors and organizations managing trials to apply for and oversee trials across 30 countries in the EU and EEA. Regulatory authorities like national competent authorities and ethics committees in EU Member States and EEA countries can also participate in assessing and overseeing trials through CTIS.

The platform is part of an extensive initiative aiming to improve the clinical trials environment in the EU/EEA, supporting large clinical trials across various European countries to enhance medical innovation and patient outcomes. Clinical trials are essential studies that evaluate the safety and efficacy of medicines, and in the case of human medicines, these studies involve human volunteers. The overarching goal is to streamline the process of conducting clinical trials in the EU and EEA, benefiting medical advancements and patients seeking innovative treatment options.
