European Clinical Trials Information Network

The European Clinical Trials Information Network is transforming access to clinical trial information for patients across Europe. By overcoming language barriers, our platform allows everyone, regardless of their native language, to easily find relevant and comprehensible clinical trial data. This innovative service connects patients to cutting-edge treatments, creating a unified European community where health and progress transcend borders.

This service is not affiliated with the European Commission, the EMA, or the official CTIS system. Most information comes from publicly available international clinical-trial registries, supplemented by data from academic centres, national regulators, and commercial sponsors. We aim to keep all content accurate and up to date.
