President Trump’s COVID-19 treatment includes an experimental antibody cocktail

After confirming early on Friday morning that President Donald Trump tested positive for SARS-CoV-2, White House physicians have sent mixed messages about the leader’s condition. Trump’s lead physician Sean Conley stated in a press conference on Saturday that the president had been sick for 72 hours, which would mean he’d attended several events after receiving a diagnosis on Wednesday morning. The White House has since said this is not the case, but reports remain confusing. While Chief of Staff Mark Meadows said on Saturday that the commander-in-chief’s vital signs were “very concerning,” tweets from President Trump and those close to him maintained that he was feeling well and reviewing documents from Walter Reed National Military Medical Center in Maryland. On Sunday, Trump’s medical team confirmed that his oxygen levels had dropped to concerning levels for a second time on Friday, and that he had suffered a high fever during that time, which seemed to contradict earlier statements.

One of the president’s treatments is quite controversial.

“I didn’t want to give any information that might steer the course of illness in another direction, and in doing so, you know, it came off that we were trying to hide something, which wasn’t necessarily true,” Conley said in a press conference on Sunday. He added that the president could return to the White House as early as Monday.

While we may not know for sure how the president is faring, we do know some of his treatment protocol. According to Conley, he’s received a single dose of an experimental antibody treatment from Regeneron Pharmaceuticals, as well as a multi-day course of the antiviral medication remdesivir. At a press conference on Sunday, his medical team announced that Trump had also received the steroid dexamethasone.

Remdesivir is a drug owned by the US pharmaceutical company Gilead, originally designed to combat Ebola. It’s an antiviral, and works not by killing the virus directly, but by inhibiting its development and replication. While remdesivir stands out as a particularly promising treatment among other potential therapies for COVID-19, its actual level of efficacy is still being determined. When speculating on possible treatments for President Trump with reporters from STAT, several clinicians noted that remdesivir would be a likely and reasonable choice if the president displayed symptoms. The National Institute of Health currently recommends that remdesivir only be administered to patients sick enough to require supplemental oxygen, which the White House previously claimed wasn’t the case for the commander-in-chief. His medical team has now confirmed that he received supplemental oxygen on Friday, but it is not clear whether he has required any since.

President Trump’s other therapies are more controversial. Regeneron’s product REGN-COV2, which is a combination of two antibodies designed to fight against the virus that causes COVID-19, has not yet received approval or authorization from the Food and Drug Administration. The president received
