US Food and Drug Administration ends emergency use of hydroxychloroquine for coronavirus

  • Trump had promoted use of antimalarial drug as Covid-19 treatment despite safety concerns
  • Agency now believes suggested dosing regimens ‘are unlikely to produce an antiviral effect’, FDA chief scientist says in letter announcing decision

The US Food and Drug Administration on Monday withdrew emergency use authorisations for two coronavirus treatments promoted by President Donald Trump despite concerns about their safety and effectiveness.

The agency revoked the authorisations for hydroxychloroquine and chloroquine after a request from Gary Disbrow, acting director of the Biomedical Advanced Research and Development Authority.

After reviewing new information from large clinical trials the agency now believes that the suggested dosing regimens “are unlikely to produce an antiviral effect”, FDA chief scientist Denise Hinton said in a letter announcing the decision.

Coronavirus: Trump says he takes malaria drug despite scientists’ concerns and no proven benefits

Critics have accused the agency of caving to political pressure when it authorised use of hydroxychloroquine and chloroquine in hospitalised Covid-19 patients in late March despite thin evidence.

More recent randomised controlled trials have found the drugs do not benefit coronavirus patients, and doctors have reported that hydroxychloroquine can cause heart problems.

Because hydroxychloroquine is approved for other uses – treating lupus and arthritis – doctors could still use it “off label” to treat coronavirus patients, and clinical trials examining their use against Covid-19 can continue.

The FDA noted that the version of chloroquine that had been authorised for emergency use is not approved in the US, so all use of that drug, donated by Bayer, will now end.

The administration’s focus on the malaria medicines in the early months of the pandemic deepened a divide between the White House and its health agencies.

Several administration officials told POLITICO they felt the drugs got outsize attention while the FDA scrambled for solutions in March. Other current and former Health and Human Services officials later said that the emergency authorities and White House demands cast a shadow on the FDA as it struggled to remain independent.

Rick Bright, the former BARDA director whom Disbrow replaced, has accused health officials of removing him from his role overseeing millions of dollars to develop treatments and vaccines because he raised health concerns about hydroxychloroquine and resisted its widespread use.

Drug makers donated millions of the pill to the government’s strategic national stockpile after Bright wrote to the FDA requesting for emergency use, a move he now says he was pressured to make.

In April, roughly a month after the FDA authorised emergency use of the drugs, the agency warned against using hydroxychloroquine outside hospitals and clinical trials because of potentially fatal cardiac side effects.

Trump toned down on mentions of the pills during his White House briefings around the same time, but in May told reporters he was taking a course of hydroxychloroquine after a White House aide was diagnosed with the coronavirus.

This month two randomised controlled trials, considered the gold standard for determining whether a drug is effective, concluded that the drug does not prevent coronavirus infection and did not help hospitalised patients.

Another study based on tens of thousands of patient records linked hydroxychloroquine to a higher risk of heart problems, but it was withdrawn after questions arose about the quality of the data it used. Doctors have anecdotally reported that the pills, especially when paired with antibiotic azithromycin, can cause heart problems like arrhythmia.

Though drug makers have donated millions of pills to federal and state governments, it is not clear how many have even been used.

Florida, for instance, is sitting on more than 980,000 unused doses from an April donation after just six hospitals put in requests for the drug.

Senate Democrats grilled FDA officials on the emergency use authorisation during a Finance Committee hearing this month. Senator Tammy Baldwin later wrote to Commissioner Stephen Hahn demanding answers on the decision and reasons it had not been revoked.
