- AstraZeneca said its severe eosinophilic asthma treatment had received orphan drug designation from US Food and Drug Administration.

The FDA grants orphan drug designation (ODD) status to medicines and potential new medicines intended for the treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the US.

'Eosinophilic oesophagitis is an allergic inflammatory disease that can affect children and adults, and typically patients experience a range of debilitating symptoms including severe pain and difficulty swallowing food,' Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D.

'Currently, there are no FDA-approved treatments for eosinophilic oesophagitis. Because Fasenra depletes eosinophils in blood and tissue, it could become a potential new medicine to treat patients with this rare disease.'
