US FDA Authorised Plasma Treatment for Coronavirus
Washington: US President Donald Trump on Sunday (Aug 23) hailed the US Food & Drug Administration (FDA) authorisation of a coronavirus treatment that uses blood plasma from recovered patients, a day after accusing the agency of impeding the rollout of vaccines and therapeutics for political reasons.
The FDA announcement of its "emergency use authorisation" of the treatment came on the eve of the Republican National Convention, where Trump will be nominated to lead his party for four more years.
"This is what I’ve been looking to do for a long time," Trump told an unusually brief White House news conference. "Today I’m pleased to make a truly historic announcement in our battle against the China virus that will save countless lives."
The FDA, explaining its decision, cited early evidence suggesting blood plasma can decrease mortality and improve the health of patients when administered in the first three days of their hospitalisation.
The agency also said it determined this was a safe approach in an analysis of 20,000 patients who received the treatment.
So far, 70,000 patients have been treated using blood plasma, the FDA said.
"It appeared that the product is safe and we’re comfortable with that and we continue to see no concerning safety signals," Peter Marks, director of the FDA’s Centre for Biologics Evaluation and Research, told reporters in a conference call.
A day before the FDA's announcement, Trump tagged the agency's Commissioner Stephen Hahn in a tweet and said, "The deep state, or whoever, over at the FDA is making it very difficult for drug companies to get people in order to test the vaccines and therapeutics."
"Obviously, they are hoping to delay the answer until after November 3rd. Must focus on speed, and saving lives!"
Trump is looking to boost his lagging poll numbers during the Republican convention this week, and progress in treatments or an effective vaccine to gain control of the virus would aid his re-election chances.
At least 5,686,377 cases of Covid-19 have been reported in the United States, according to a Reuters tally, and more than 176,000 Americans have died.
Mr Michael Steele, who served as chairman of the Republican National Committee from 2009 to 2011, said the Trump administration was putting politics ahead of science.
"This is not about good science or even your health, it’s about his re-election," Mr Steele wrote on Twitter.
Plasma is the element of blood that carries water, enzymes and blood cells throughout the body. It also carries the antibodies humans form to fight off disease and boost immunity.
Covid-19 patients have been receiving convalescent plasma for several months through clinical trials at medical centres such as New York’s Mount Sinai Hospital and Johns Hopkins.
Supplies of plasma are limited because they require that a recovered Covid-19 patient donate blood and that it matches the blood type of the recipient.
Reuters reported that Covid-19 plasma supplies are dwindling, with the American Red Cross saying its stockpile of plasma for Covid-19 patients declined 70 per cent in July.
US regulators provided emergency authorisation for Gilead Science Inc’s remdesivir as a therapeutic treatment for Covid-19 earlier this year.
Reuters reported that a senior administration official said therapeutic drugs that are being studied specifically for Covid-19 could be authorised for use and making doses by fall.
