Once again, on 20 May, on the occasion of World Clinical Trials Day, the Spanish Association of Orphan and Ultra-Orphan Drug Laboratories (AELMHU) presents its Annual Report on Clinical Trials in Rare Diseases in Spain.

This report shows that Spain continues to exponentially increase its commitment to research in clinical trials focused specifically on rare diseases, with 225 studies authorised. This means that 23% of new studies are focused on rare diseases.
