On May 18, 2022, the U.S. National Institutes of Health announced it had awarded approximately $577 million to establish nine Antiviral Drug Discovery (AViDD) Centers for Pathogens of Pandemic Concern.

The AViDD centers will conduct innovative, multidisciplinary research to develop candidate COVID-19 antivirals, especially those that can be taken in an outpatient setting, as well as antivirals targeting specific viral families with high potential to cause a pandemic in the future. These include paramyxoviruses, bunyaviruses, togaviruses, filoviruses (including Ebola viruses and Marburg virus), picornaviruses (including enteroviruses and other cold-causing viruses), and flaviviruses (including the viruses that cause yellow fever, dengue and Zika).

The AViDD centers will conduct research on the early-stage identification and validation of novel viral targets, with an eye to identify small molecules and biotherapeutics that directly block viral targets. As drug candidates are identified and evaluated for properties such as potency and breadth, the most promising will enter late-stage preclinical development. Importantly, the centers can draw on the resources of their industry partners to accelerate research, making use of the companies’ chemical libraries and expertise in moving candidates into the product development pipeline.
