The company offers zanamivir, a neuraminidase inhibitor for the treatment and prevention of influenza, which it markets under the Relenza brand name through a licensing agreement with GlaxoSmithKline. It also provides influenza diagnostics test kits, such as BioStar OIA FLU that detects influenza and assists the physician to differentiate influenza from other respiratory infections which may display similar symptoms; and Biostar OIA FLU A/B, a differentiated flu test. In addition, the company develops nucleoside analogues designed to treat hepatitis C virus infections, licensed to Boehringer Ingelheim; and a series of candidate drugs aimed at the treatment of respiratory syncytial virus disease.
