Fujifilm Holdings Corp. announced on October 22, 2020, that it has partnered with Shanghai-based Carelink Pharmaceutical Co. to seek approval in China for the antiviral medication Avigan to treat both COVID-19 and influenza.
Avigan selectively inhibits RNA polymerase necessary for influenza virus replication. Due to this mechanism of action, it has been expected that Avigan may have an antiviral effect on the novel coronavirus SARS-CoV-2, as they are RNA viruses of the same type as influenza viruses.
