GigaGen announced that it is developing a recombinant polyclonal antibody therapy for the treatment of COVID-19, the pandemic coronavirus that has been sweeping the world and for which humans have no innate immunity. Based in South San Francisco, GigaGen spent the first seven years of its existence developing its single cell technology drug discovery and development platform, often raising money just on ideas during that period. It eventually came up with a powerful way to make recombinant polyclonal antibodies and now has a pipeline targeting infectious disease, transplant rejection, and checkpoint resistant cancers.
