Where does this information come from?

How this page is built
Everything on this page is copied from public registry records — it is not written from memory, and nothing here describes the organisation beyond its registered trials. Each trial links to its own record so you can check it yourself.
- ClinicalTrials.gov (U.S. National Library of Medicine) ↗ Trial IDs, titles, lead sponsor, phase, overall status, start date, conditions and intervention names
- EU Clinical Trials Information System (CTIS) ↗ EU trial numbers, titles, sponsor, phase, status, therapeutic area and member-state countries
This page is built automatically: a daily sync job reads the registry records behind our trial registers and groups every current trial by its lead sponsor name, ignoring legal-form suffixes such as Inc. or Ltd. A small, hand-checked list joins the same organisation's different registry names (for example its EU legal entity). There is no AI drafting and no per-sponsor editorial pass. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The the registries data on this page was last retrieved on 10 Nov 2026. How every register is built: methodology · fixes we have made: corrections log.
