How this page is built

Every row is copied from the EMA's orphan designations data, reproduced with acknowledgement of the source. Each substance links to its official EMA page.

A daily job downloads the EMA's orphan designations JSON report and lists every designation, newest first. No AI drafting and no editorial pass. See our editorial standards. The the EMA data on this page was last retrieved on 27 Sep 2026.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician โ€” our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error?
