(Bloomberg) –
President Donald Trump has said that a remedy for coronavirus that reaches blood plasma donated through other people who have recovered from Covid-19 will prolong more Americans in poor health, expanding access to a promising cure before researchers fully sense how well it works.
“This is tough therapy,” Trump said at a press conference at the White House. “Today’s action will be greatly extended to this treatment.”
The U.S. Food and Drug Administration demonstrated Sunday that it has removed so-called convalescent plasma for use in some patients. The resolution would make it less difficult to obtain treatment, which Trump has promoted even if studies appear that his benefits have not been completed. Bloomberg News previously reported that the announcement is imminent.
Trump, who saturday accused regulators of slow action to reduce their chances of re-election, said the FDA had concluded that the treatment was “safe” and “very effective.” The full set of clinical trials required for drugs submitted for firm approval has not yet been submitted.
Senior Trump management officials said that even without a full clinical trial, the case for allowing more people to get convalescent plasma was strong and suggested that Americans with poor health donate plasma. Infusion to antibody patients collected from others has been used to treat infections after viral outbreaks for about a century.
“Convalescence plasma has been a proven healing remedy in past outbreaks,” Health and Human Services Secretary Alex Azar said at the press conference.
In addition, officials stated that the knowledge gathered from a large number of patients who obtained treatment through a program administered by the Mayo clinic had convincingly justified the authorization. FDA commissioner Stephen Hahn said researchers had discovered a 35% improvement in the survival of patients treated with convalescent plasma.
“We dream of the progression of the drug with anything with 35% relief in mortality,” Azar said. “This is a first step forward in treating patients.”
However, the statements exaggerated the actual results. In fact, patients treated with plasma containing the highest degrees of antibodies were 35% more likely than those with lower grade plasma.
It is not yet known whether patients treated with plasma are less likely to die than those who are not treated with this substance.
However, the authorization is in addition to a developing list of remedies that doctors must have to combat Covid-19. In May, the FDA granted emergency approval to remdesivir, an antiviral drug from Gilead Sciences Inc. And an older steroid, dexamethasone, has a widely used tool to fight the virus.
The shares of Grifols SA of Spain, which Equita analyst Gianmarco Bonacina described as one of the leading suppliers of blood products in the United States, rose 4%.
Blame the slowdown
Some infectious disease experts say scientists continue to examine the use of convalescent plasma in clinical trials before expanding access to treatment.
Thomas M. File, president of the Infectious Diseases Society of America, said in a statement that the organization “supports the ongoing collection of clinical trial knowledge to better perceive the benefits of the convalescent plasma remedy before authorizing its wider use in Covid-19 patients. . “
Several clinical trials are underway, but many have had disorders that recruited participants due to the expanded program at the Mayo Clinic, which provides treatment to all patients. In one clinical trial, some patients get a random placebo.
Trump staff leader Mark Meadows accused the feds the Sunday before of curbing America’s pandemic reaction to the virus pandemic, which has killed more than 175,000 Americans so far, before what had been announced as a “therapeutic advance.”
The coronavirus epidemic is weighing heavily on Trump’s prospects for re-election. About 58% of Americans disapprove of their control of the pandemic, while 40% approve, according to an average of RealClearPolitics surveys on the issue.
While the United States still has the number of deaths in the world, coronavirus-related deaths in the country have fallen below 1,000 for the first time in five days. Texas, Florida and Arizona reported decreases in cases and deaths.
After Trump claimed Saturday that FDA workers had planned delays to sabotage his re-election, Meadows said the president’s tweet reflected the “frustration” of the agency’s bureaucrats.
“They need to do things the way they have,” Meadows said in ABC’s “This Week.” “This president needs to reduce bureaucracy. That’s what tweet was all about.
Meadows warned that one component of the explanation for why Trump tweeted about the FDA is that he needs federal fitness agencies to “feel the heat” to get results. In “Fox News Sunday,” Meadows said, “The announcement that comes today was made several weeks ago.”
“It was a trial and error by several other people in the federal government who deserve to have done it differently, and having been personally involved, you have to make them feel the heat if they don’t see the light,” he said. says Array
Commercial distribution
Former FDAcommissioned Scott Gottlieb, who left the Trump administration in April 2019, said Sunday on CBS that there were “perceived delays” in allowing blood plasma due to considerations from senior fitness officials.
“It was reported this week that [the National Institutes of Health] had doubts about the FDA going ahead with this authorization. But there are reasons why other people have questions,” Gottlieb said in “Face the Nation.” “The trial, which will be based on 70,000 patients, is not a very vigorous trial.”
The emergency usage order will likely allow for greater distribution of advertising “and will make it less difficult for plasma product brands to cost,” he said. “But in the end, it’s widely available right now. Patients perceive it.”
Separately, the Financial Times reported Sunday that Trump plans to circumvent U.S. general regulatory criteria. To boost an experimental vaccine against UK coronavirus to be used in the US. Before the November election, through an US.
A HHS spokesman, who oversees the FDA, told the paper that any claim that an emergency use authorization would be issued prior to the election was “absolutely false.”
Data distinction
Data from the Mayo Clinic, published on an online page used through researchers to disseminate their findings before they are officially published, showed that patients who received plasma convalescent with the highest levels of antibodies were 35% more likely than those with decreasing grades. Matrix While the remedy with higher degrees of antibodies advanced in survival, all patients gained convalescent plasma.
The difference was documented at Trump’s press conference, where the president said the treatment had proven to be “very effective” and Hahn said the product itself, not its exact composition, stored lives.
“A 35% improvement in survival is a really extensive clinical benefit,” Hahn said. “What this means is that if knowledge continues to materializing, another hundred people with Covid 19, 35 would have been stored through plasma administration.”
The study showed that treating the other hundred people who would otherwise have died with higher levels of antibodies accumulated 35 lives, compared to giving them all the plasma sets with lower doses of antibodies. This does not allow us to know how they would have behaved in relation to popular treatment.
