US President Donald Trump’s remarks came hours after the US Food and Drug Administration revoked its emergency use authorization for hydroxychloroquine to treat Covid-19.
The US Food and Drug Administration on Monday revoked its emergency use authorization for hydroxychloroquine to treat Covid-19 after ignoring all positive studies of HCQ worldwide. President Donald Trump commented “only US agencies have failed to grasp its benefit in fighting the coronavirus.”
The FDA also warned that the drugs have been shown in lab studies to interfere with Gilead Sciences Inc’s antiviral drug remdesivir – a drug that showed some benefit against Covid-19 in a non peer reviewed preprint.
Oxford University that have secured a place in a $ 1 billion funding grant to develop a vaccine, “surprisingly” halted a trial after deciding that hydroxychloroquine was “useless” at treating Covid-19 patients. The trials lead seemed to have hydroxychloroquine confused with a similar drug for amoebic dysentery. That may explain why they had been dosing at 4 times the recommended dosage, a rate that was potentially fatal, with 34 times worse outcome than other studies.
“I took it and I felt good about taking it. I don’t know if it had an impact, but it certainly didn’t hurt me,” Trump said.U.S. President Trump
Trump said there had been “great reports” out of France, Spain and other places, without offering any evidence or further explanation. France is one of the countries that has already stopped using the drug for Covid-19 patients.
US Secretary of Health and Human Services Alex Azar said the drug is still being studied for possible use at an earlier stage of the disease.
“A lot of the data that has come out that was more negative was people who were quite ill in the hospital,” he said.Alex Azar U.S. Secretary of Health and Human Services
The drug can still be used with a doctor’s prescription, Azar noted. Any drug with US approval can be used in any way a doctor sees fit regardless of what it has been approved for.
Hundreds of trials testing hydroxychloroquine or chloroquine as interventions for Covid-19 are still underway, including a US study designed to show whether hydroxychloroquine in combination with azithromycin can prevent hospitalization and death from Covid-19.
There have been dozens of positive studies that main stream media are incapable of sourcing.
