After President Trump praised the effectiveness of the antibody mixture, Regeneron filed for emergency use with the US Food and Drug Administration.
In a 5-minute video, Trump praised Regeneron’s antibodies for making him healthy. “This is a treatment,” he said, along with the promise that all hospitals would soon have this antibody.
When the body is invaded by a virus, the immune system produces antibodies, which are proteins that can recognize and destroy the virus. Regeneron’s antibody mix, called REGN-COV2, consists of an antibody invented by the company and another from patients cured with Covid-19. The combination is believed to increase your ability to react and fight the virus.
Initial data from a clinical trial show that the amount of nCoV is reduced in patients. However, the company has not released detailed data and the tests are not yet complete. Experts argue that more data is needed to assess the effectiveness of the treatment before it is widely used.
After Trump was treated for Covid-19 with a mixture of antibodies, many patients wanted to take it and register for the trial. The company said it can currently serve 50,000 patients.

Dr. Gary Kleiner, a pediatric immunologist at Miami Miller University School of Medicine and Regeneron’s antibody testing investigator, said many patients have seen and are looking forward to it in the past week.
Dr. Dirk Sostman, chief of research at the Houston Methodist Hospital, which tests antibodies from the companies Regeneron and Eli Lilly, says more and more patients are asking to participate. You are concerned about the lack of details in the press release and should be careful to use it widely.
America’s top infectious disease specialist, Dr. Anthony Fauci, said he was “very skeptical” about Regeneron’s efficacy in Trump’s Covid-19 treatment. Serious research is needed to show real effectiveness, he stressed.
Dr. Edward Jones-Lopez, infectious disease specialist at the University of Southern California Los Angeles School of Medicine, commented: “In the short term, but Mr. Trump has responded and is in better health, possibly because action of antibodies “.
Regeneron spokeswoman Alexandra Bowie said in an emailed statement: “Patients who respond to the antibody test have health conditions similar to those of President Trump.”
The federal government has invested $ 500 million in the development and production of the Regeneron antibody blend. The money is part of the Operation Warp Speed project, an effort to bring in potential Covid-19 vaccines and treatments and distribute them with the license.
The company plans to provide Covid-19 to 300,000 patients for free over the next several months, according to an agreement with the federal government. In August, Regeneron partnered with Roche to boost production to 250,000 doses per month over the next year.
