While the world is transfixed by the high-stakes race to develop a COVID-19 vaccine, an equally crucial competition is heating up to produce targeted antibodies that could provide an instant immunity boost against the virus. Clinical trials of these monoclonal antibodies, which could both prevent and treat the disease, are already underway and could produce signs of efficacy in the next few months, perhaps ahead of vaccine trials. “If you were going to put your money down, you would bet that you get the answer with the monoclonal before you get the answer with a vaccine,” says Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases (NIAID).
“Antibodies have the potential to be an important bridge until the vaccine is available,” says Ajay Nirula, a vice president at Eli Lilly, one of several large companies investing in them. Likely to be more effective than the repurposed drugs now available, such as remdesivir and dexamethasone, antibodies could protect the highest risk health care workers from becoming infected while also lessening the severity of COVID-19 disease in hospitalized patients. But making monoclonals involves growing lines of antibodymaking B cells in bioreactors, raising concerns they could be scarce and expensive. On 15 July, Lilly, AbCellera, AstraZeneca, GlaxoSmithKline, Genentech, and Amgen jointly asked the U.S. Department of Justice (DOJ) whether they could share information about manufacturing their monoclonals without violating antitrust laws, “to expand and expedite production.”
