The treatment is “super promising, and all of us are excited from a theoretical perspective,” Dr. Ranney said. “But it’s just too early,” she added, to tell if theory will translate into practice.
Monoclonal antibodies are synthetic, mass-produced mimics of the molecules the human body produces in response to an infection. Some antibodies are powerful enough to block the coronavirus from infiltrating cells. Administered to people battling the coronavirus, the monoclonal antibodies could help naturally produced immune molecules fend off the virus.
Just days before Mr. Trump tested positive for the coronavirus and was admitted to the hospital, Regeneron announced a batch of preliminary results, collected from ongoing trials, via news release. They suggested Regeneron’s monoclonal antibody cocktail could tamp down the amount of virus found in the nasal cavity, and
