(“Bukwang”) announced that patent application of its antiviral agent Levovir (active ingredient: Clevudine) against SARS-Cov-2 virus isolated from a sample of a Korean coronavirus infectious disease-19 (COVID-19) patient has been granted on 11st August. The patent application which was filed in March this year was proceeded under expedited examination system, making it possible to be registered very quickly.

The registered patent was filed with Levovir’s experimental data in human lung cells (CALU-3 cells) where Remdesivir was used as positive control, and in non-human primate kidney cells (VERO cells) where lopinavir-ritonavir, and chloroquine were also tested.
