About NanoViricides

NanoViricides, Inc., is a publicly traded company (NYSE American: NNVC) (the "Company"), and a clinical stage, leading global pioneer in the development of broad-spectrum antivirals based on host-mimetic nanomedicine technology that viruses and their variants cannot escape. Its clinical stage, broad-spectrum, antiviral drug NV-387 has been granted an "Orphan Drug Designation" (ODD) by the US FDA Office of Orphan Products Development (OOPD). This could provide 7 years market exclusivity, tax credits for clinical trial costs, and fee exemptions upon approval.
