Synairgen is a drug discovery and development company founded by University of Southampton Professors Stephen Holgate, Donna Davies and Ratko Djukanovic.


The business, focused primarily on severe asthma and COPD, uses its differentiating human biology BioBank platform and world-renowned international academic Key Opinion Leader network to discover and develop novel therapies for respiratory disease.

Leveraging its scientific and clinical facilities at Southampton General Hospital, the Company uses in vitro and ex vivo models to progress opportunities into clinical development. The BioBank of human samples is used in these models to increase confidence in the likelihood of successful drug development.

Core to Synairgen’s business strategy is the realisation of value via licensing transactions – as demonstrated through the out-licensing of SNG001 to AstraZeneca in 2014.

Synairgen is quoted on the London Stock Exchange (LSE:SNG).
