EU Clinical Trial Map
The European Medicines Agency (EMA) has launched the EU Clinical Trial Map, offering real-time data from the EU Clinical Trials Information System (CTIS).
This interactive tool helps patients, caregivers, and healthcare professionals easily search for clinical trials across Europe in simple language.

How to Use the EU Clinical Trial Map to Find PNH Trials
- Navigating: Drag the map with your mouse, zoom in/out, or click the home button to reset the view.
- Searching for PNH Trials: enter “Paroxysmal Nocturnal Hemoglobinuria” or “PNH” in the search bar under “Medical condition” to display all trial locations (both recruiting and not recruiting) on the map.
- To find trials which are recruiting: Trials recruiting PNH patients are marked in yellow. Check the “Only show recruiting” box to filter these.
- Searching by Location: Use the “Country” drop-down to select regions or countries.
- Viewing Trial Details: Click the yellow or blue dots on the map for trial information, including contact details and eligibility. Access full trial records via the EU CTIS portal.
