The drug EIDD-1931 was effective against SARS and MERS viruses in the laboratory, and a modified version (EIDD-2801) could potentially be valuable against 2019-nCoV.
An antiviral compound discovered at Emory University could potentially be used to treat the new coronavirus associated with the outbreak in China and spreading around the globe. Drug Innovation Ventures at Emory (DRIVE), a non-profit LLC wholly owned by Emory, is developing the compound, designated EIDD-2801.
In testing with collaborators at the University of North Carolina at Chapel Hill and Vanderbilt University Medical Center, the active form of EIDD-2801, which is called EIDD-1931, has shown efficacy against the related coronaviruses SARS (Severe Acute Respiratory Syndrome)- and MERS-CoV (Middle East Respiratory Syndrome Coronavirus). Some of the data was recently published in Journal of Virology.
EIDD-2801 is an oral ribonucleoside analog that inhibits the replication of multiple RNA viruses, including respiratory syncytial virus, influenza, chikungunya, Ebola, Venezuelan equine encephalitis virus, and Eastern equine encephalitis viruses.
“We have been planning to enter human clinical tests of EIDD-2801 for the treatment of influenza, and recognized that it has potential activity against the current novel coronavirus,” says George Painter, PhD, director of the Emory Institute for Drug Development (EIDD) and CEO of DRIVE. “Based on the drug’s broad-spectrum activity against viruses including influenza, Ebola and SARS-CoV/MERS-CoV, we believe it will be an excellent candidate.”
“Our studies in the Journal of Virology show potent activity of the EIDD-2801 parent compound against multiple coronaviruses including SARS and MERS,” says Mark Denison, MD, the Stahlman Professor of Pediatrics and director of pediatric infectious diseases at Vanderbilt University School of Medicine. “It also has a strong genetic barrier to development of viral resistance, and its oral bioavailability makes it a candidate for use during an outbreak.”
“Generally speaking, seasonal flu is still a much more common threat than this coronavirus, however, novel emerging coronaviruses represent a considerable threat to global health as evidenced by the new 2019-nCoV,” said Ralph Baric, PhD, an epidemiology professor at the University of North Carolina’s Gillings School of Global Public Health. “But the reason the new coronavirus is so concerning is that it’s much more likely to be deadly than the flu – fatal for about one in 25 people versus one in 1,000 for the flu.”
The development of EIDD-2801 has been funded in whole or in part with Federal funds from the National Institute of Allergy and Infectious Diseases (NIAID), under contract numbers HHSN272201500008C and 75N93019C00058, and from the Defense Threat Reduction Agency (DTRA), under contract numbers HDTRA1-13-C-0072 and HDTRA1-15-C-0075, for the treatment of Influenza, coronavirus, chikungunya, and Venezuelan equine encephalitis virus.

About Defense Threat Reduction Agency: The Defense Threat Reduction Agency (DTRA) was formally established on October 1, 1998. DTRA enables the Department of Defense, the United States Government and International partners to counter and deter weapons of mass destruction and improvised threat networks. As a Combat Support Agency and a Defense Agency, DTRA's mission is to counter the threats posed by the full spectrum of weapons of mass destruction (WMD), including chemical, biological, radiological, nuclear, and high-yield explosives; counter the threats posed by the growing, evolving categories of improvised threats, including improvised explosive devices, car bombs and weaponized consumer drones, as well as the tactics, technologies and networks that put them on the battlefield; and ensure the U.S. military maintains a safe, secure, effective and credible nuclear weapons deterrent.
