Hydroxychloroquine: how an unproven drug became Trump’s coronavirus 'miracle cure'

Donald Trump has continued to promote hydroxychloroquine as a possible remedy for coronavirus.
Donald Trump has continued to promote hydroxychloroquine as a possible remedy for coronavirus.

This weekend, Donald Trump used his daily White House coronavirus briefings to again urge Americans to take hydroxychloroquine, an anti-malaria drug that has not been shown to be safe or effective against Covid-19.
“What do you have to lose? Take it,” the president said on Saturday as he boasted that the US had amassed 29m doses of the drug. On Sunday, facing questions from the press about his aggressive promotion of an unproven treatment, he argued against waiting for the completion of clinical trials. “In France, they had a very good test,” he said. “But we don’t have time to go and say, ‘Gee, let’s take a couple of years and test it out, and let’s go and test with the test tubes and the laboratories.’”
Meanwhile, Dr Anthony Fauci, the country’s top infectious disease doctor, has repeatedly warned that there is no conclusive evidence to support using the drug. Asked whether it should be considered a treatment for Covid-19, he said on 24 March: “The answer is no.”
The story of how hydroxychloroquine was anointed the Trump administration’s miracle drug for the coronavirus pandemic is a distinctly modern tale of misinformation within a global information ecosystem beset by widespread uncertainty, fear, media fragmentation and hyper-partisanship. Belief in the drug’s potential to cure patients infected with the virus followed an extraordinary trajectory from a small study conducted in France (Trump’s “very good test”) to Silicon Valley social media influencers, Fox News and the largest bully pulpit: the White House.
But it’s also a story as old as medicine itself. When an epidemic killed thousands in ancient Rome, said Aaron Shakow, a research associate at Harvard Medical School and historian of medicine, the chief physician of the emperor Nero circulated a recipe for an old miracle cure.
“It was an attempt by Nero to sustain his legitimacy in the midst of this catastrophic event,” Shakow said. “Epidemics are dangerous to rulers.”

A deeply flawed study

In early March, as the coronavirus pandemic accelerated its spread around the globe, a group of scientists in Marseille, France, launched an experiment to see whether hydroxychloroquine, a well-known old malaria drug, could be what everyone was searching for: a cure.
Most small scientific studies live and die within the rarified domain of academic journals, but the French trial had a much more auspicious debut. Before the study was even published, in the International Journal of Antimicrobial Agents (IJAA), a lawyer falsely claiming an affiliation with Stanford University appeared on Fox News’s Tucker Carlson Tonight to declare the results: a “100% cure rate against coronavirus”. From Fox News, it was only a matter of time (hours, in fact) before the drug was being hailed as a “game changer” by the president of the United States.
Trump made his first endorsement of hydroxychloroquine on 19 March. Export controlsshortagesoverdoses and scientific recriminations rapidly ensued, but the controversy could not extinguish the power of presidentially endorsed hope. Across the globe and throughout diverse communities on the internet, hydroxychloroquine had been anointed the miracle cure for Covid-19.
The only problem? The study that all this fervid hope is based on doesn’t show what its authors claim it does.
The gold standard for a clinical trial is a double-blinded, randomized controlled trial (RCT). What this means in plain English is that the study has been designed to reduce biases that would render its results meaningless. Neither the physician nor the patients knows whether they received the drug (“double-blinded”), a safeguard that reduces the possibility that the doctor will treat the two groups differently. The researchers also do not get to choose which patients go into which group (“randomized”) and the makeup of the two groups is roughly equivalent (“controlled”).
The French hydroxychloroquine study did not follow any of these rules.
The treatment group and the control group were drawn from separate populations: the treatment group were all patients at the institution where the researchers worked, the Méditerranée Infection University Hospital Institute in Marseille, while the control patients came from other hospitals in the south of France. The treatment group (mean age 51.2) was significantly older than the control group (mean age 37.3), introducing another variable that could undermine the meaning of the results. The study was “open label”, meaning the physicians and patients knew which treatment they were receiving. The French researchers also treated some but not all of the treatment group patients with azithromycin, a common antibiotic, another complicating factor that was not randomized.
But even more important than these shortcomings in the design of the study is how the researchers chose to measure and report their results. Forty-two patients were initially included in the study. Three were transferred to the intensive care unit; one died, one left the hospital, and one stopped taking the treatment due to nausea. The other 36 eventually recovered, and those who received the drug cleared the virus from the system faster than those who did not.
If you had only heard about this study from the Fox News assertion of a “100% cure rate”, you might assume that the four patients with poor clinical outcomes (the three ICU visits and one death) had been unlucky enough to be in the group that did not receive the “cure”.
And yet, those four patients, as well as the patient with nausea and the one who left the hospital early, were all part of the treatment group. They were excluded from the topline results of the study because of the way that the researchers chose to measure and report the results: strictly based on the measurable presence of viruses in nasal swabs taken each day of the study. Since the patients were in the ICU or dead, their samples could not be taken and they were left out of the final analysis. Based on the nasal swabs of just the 36 patients who completed the study, those who received the drug cleared the virus from their systems faster than those who did not.
This is how an experiment in which 15% of the treatment group and 0% of the control had poor clinical outcomes could end up being reported as showing a “100% cure rate”.

On 3 April, two weeks after the study was first published online, the International Society of Antimicrobial Chemotherapy, which publishes the IJAA, said in a statement that the group’s board “believes the article does not meet the Society’s expected standard, especially relating to the lack of better explanations of the inclusion criteria and the triage of patients to ensure patient safety”.
Didier Raoult, the corresponding author for the French study, did not respond to questions from the Guardian.
Andrew Noymer, a professor of public health at the University of California, Irvine, described the results of the French study as “meaningless”. “They should have done an RCT,” he said.
“This idea that we’re all manning the lifeboats and there’s no time for that is just absurd,” Noymer added. “They could have already done it. They could have had the answer by now … Doctors have always gone with their guts and saved many lives, but I don’t know. If they had done RCTs on Thalidomide” – a drug that caused birth defects – “they would have figured out its dangers a lot sooner.”

From Silicon Valley to Fox News

So how did one interesting but flawed study out of the south of France make its way to Fox News’s prime time and the White House?
It was not surprising that scientists were interested in testing hydroxychloroquine (and its close relative, chloroquine), a well-known and understood drug, as a potential treatment against Covid-19. It is one of a number of possible treatments that scientists in China and South Korea looked at in the early stages of the coronavirus outbreak, including in vitro (ie lab-based) experiments that showed promising (though not conclusive) results. The drug was also selected as one of four that the World Health Organization included in its large-scale international clinical trial.
These drugs are helping our coronavirus patients,” declared the headline of the Journal op-ed, which was written by two physicians from Kansas, Jeff Colyer and Daniel Hinthorn. The pair wrote that they had been treating patients with hydroxychloroquine and azithromycin, and encouraged others to do so too “as a matter of clinical practice” once a patient tests positive. They also recommended using the drug prophylactically for healthcare workers.
The doctors did not provide any data from their own patients, but referenced the French study, writing: “Researchers in France treated a small number of patients with both hydroxychloroquine and a Z-Pak, and 100% of them were cured by day six of treatment.”
Hinthorn, the director of the division of infectious diseases at the University of Kansas medical center, responded to queries from the Guardian about the op-ed’s mischaracterization of the French study: “You are correct. Any patient left out of any analysis makes us suspicious. But what this study told us was that this was a combination that might merit further evaluation.”
He acknowledged that it is unknown whether the drug is beneficial or harmful for Covid-19 patients, but said that since no drug has as yet been proven effective, “if there is any medication that might give hope, we prefer to try it” as long as it is safe. “We should know in the next few weeks whether such a regimen was a wise decision or not.”
Hinthorn did not respond to a follow-up question about whether the op-ed should be corrected to more accurately reflect the degree of uncertainty around hydroxychloroquine. Colyer, the former governor of Kansas and a plastic surgeon, did not respond to requests for comment. He has since written a second op-ed for the Journal, also promoting hydroxychloroquine.
But while hydroxychloroquine was garnering some interest in the early days of the pandemic, other possible treatments, such as Gilead’s antiviral Remdesivir, were drawing more. Google trends data shows that people were searching for Remdesivir more than hydroxychloroquine throughout most of February.
What Remdesivir lacked that hydroxychloroquine had, however, was a team of dedicated hype men who appeared more interested in publicizing the drug as a cure than they were in discovering whether the drug was effective.
Among these is Raoult, the French physician who co-authored the hydroxychloroquine study in Marseille. Before Raoult had even begun his clinical trial, in late February, he appeared in the press to promote the idea of chloroquine as a treatment, researchers with First Draft News found. A video of the appearance received more than a quarter-million views on Facebook.
Raoult also found a dedicated and effective English-language publicist in Gregory Rigano, the lawyer who appeared on Fox News with a chyron that falsely labeled him an “adviser” to Stanford medical school. Rigano wrote a Google document promoting the use of chloroquine with James Todaro, a blockchain investor who received a medical degree from Columbia University but does not appear to practice. (The document initially listed a third co-author, a retired biochemist who disclaimed any knowledge of it when contacted by Wired.)
The Google document, which was formatted in a way that made it appear to be a scientific paper, found an audience among Silicon Valley’s elite. It was shared on Twitter by a number of influential investors before it hit the virality motherlode: on 16 March, the billionaire entrepreneur Elon Musk tweeted the link to the document to his nearly 33 million followers.
“When someone who is newsworthy or notable that has an enormous network on social media tweets about something that could be as path-breaking as a medicine that could treat coronavirus, everyone is going to pay attention no matter if that person has expertise or not,” said Joan Donovan, director of the technology and social change research project at Harvard’s Shorenstein Center. “Elon Musk elevating and giving voice to this Google doc does act as a validating mechanism. Elon Musk is a tech entrepreneur best known as a car salesman, but nevertheless people look to him for what’s new, what’s next.”
Musk’s tweet received more than 13,000 retweets. (He did not respond to questions from the Guardian about his promotion of the document.) Search interest in chloroquine soared. Mainstream media outlets covered his apparent endorsement of the drug. An 85-year-old medication was well on its way to becoming a Covid-19 meme.

America’s right wing piles on

Once Trump declared himself a proponent of hydroxychloroquine, the scientific debate over the drug was drowned out by a decidedly partisan one.
Rightwing media outlets have followed Fox News’s lead (an analysis by Media Matters found that the cable news channel promoted using the drug 109 times between 23 and 25 March) to become staunch proponents of the drug, from digital outrage factories such as the Daily Caller and the Daily Wire to the opinion pages of the Wall Street Journal.
Researchers at the University of Minnesota Genomics Center investigate the drug.

The idea that hydroxychloroquine is “the cure” has taken off within certain online communities, including among anti-vaxxers and followers of QAnon, a rightwing conspiracy theory. The drug has also found support from the Association of American Physicians and Surgeons, a small, ultra-conservative organization that advocates against government involvement in medicine. The group launched a texting campaign to bombard physicians with demands to sign a petition against “red tape” that might prevent them from prescribing the drug, Reuters reported.

Calls for further research

Away from the rancor of the partisan media, scientists and physicians continue to study the effects of the drug. In some states, including the hard-hit New York, hospitals are following Hinthorn’s rationale and using the drug since no proven therapy exists.
A group of French researchers published a refutation of the Raoult study in Médecine et Maladies Infectieuses on 30 March. The researchers, at Saint Louis hospital in France, followed the same regimen of hydroxychloroquine for 11 patients, and did not have similar results. “We found no evidence of a strong antiviral activity or clinical benefit of the combination of hydroxychloroquine and azithromycin for the treatment of our hospitalized patients with severe Covid-19,” they wrote. “Ongoing randomized clinical trials with hydroxychloroquine should provide a definitive answer regarding the alleged efficacy of this combination and will assess its safety.”
But another study – this time a randomized controlled trial – out of Wuhan, China, has sparked hope since it was circulated ahead of publication on 31 March. The trial of 62 patients found that patients with mild cases of Covid-19 who were treated with hydroxychloroquine recovered faster than those who did not – and none of them progressed to “severe” illness. The study has not yet been peer-reviewed.
The authors of the study urged further research and large-scale clinical trials to better understand how the drug operates and how best to use it.

The danger of presidential misinformation

The hype around hydroxychloroquine has not been without casualties.
Heightened demand for the drug has left longtime patients – including lupus patients who have long used it as an anti-inflammatory – forced to go without. Overdoses have also been reported in the US and Nigeria as frightened individuals attempt to self-medicate.
Social media companies, who have been proactive about policing misinformation about coronavirus, have taken some steps to counter the spread of false claims. Google took down the Google document by Rigano , though the company has not responded to numerous requests for an explanation. Twitter has also deleted tweets by the Brazilian president, Jair Bolsonaro, Trump attorney Rudy Giuliani, and the Fox News personality Laura Ingraham that touted the efficacy of hydroxychloroquine.
But it’s hard to see how these small enforcement actions by internet platforms can have much of an impact when the president of the United States continues to use his platform to promote the drug, as he did during his daily briefings on Saturday and again on Sunday.
Trump’s promotion of the drug has raised questions about his motivation, and on Monday the New York Times reported that the president holds “a small personal financial interest” in Sanofi, the company that makes a brandname version of hydroxychloroquine. (The drug’s patent has expired so other pharmaceutical companies can manufacture generic versions.)
As a piece of viral misinformation, the hydroxychloroquine meme has amassed an extraordinary list of validators, starting with its placement in a respectable peer-reviewed journal. (Though misinformation stemming from academia is not without precedent; the paper that touched off the false belief in a link between autism and the measles vaccine was published in one of the most respected publications in medicine, and only retracted 12 years later.) It’s also very difficult to refute, because none of the hydroxychloroquine narrative’s critics can or will say anything definitive about its efficacy. Uncertainty and a call to await further study is a weak sword to bring to a fight against an overly confident propagandist.
Trump’s unscientific embrace of hydroxychloroquine is not common, but there are historical examples of heads of state spreading misinformation during pandemics. One recent, tragic example is the HIV-denialism of the South African president Thabo Mbeki, who rejected the use of antiretroviral drugs for his country’s citizens and instead promoted nutritional remedies such as beetroot juice and garlic. Researchers at the Harvard school of public health ultimately placed the death toll of Mbeki’s policies at approximately 330,000.

Noymer, the UC Irvine epidemiologist, said that the two situations were not quite analogous, since hydroxychloroquine has a “plausible mechanism” to combat the coronavirus, while beetroot juice never did.
Still, Noymer said that the influence that a president can have over a population’s attitude toward a medicine or drug is significant. He recalled President Gerald Ford publicly receiving a flu shot in 1976, amid fear that a new swine flu could lead to a pandemic.
“There was a photograph of him rolling up a sleeve and getting a shot, and the uptake on the flu shot was enormous,” Noymer said. “When the president of the United States does something, it’s quite the endorsement.”
As for Trump, it does not appear likely that he will stop hyping the drug anytime soon, nor that he will take responsibility if anything goes wrong.
“What do you have to lose?” he said on Sunday. “They say, take it. I’m not looking at it one way or the other … If it does work, it would be a shame if we didn’t do it early. I’ve seen things that I sort of like, so what do I know?
“I’m not a doctor.”


  1. your all idiots. this was not just the france test. It was used in Korea, China and against SARS and other similar viruses with complete success. Its effectiveness is proven at the biological levell

  2. This drug has been used in the past SARS outbreaks and showed excellent effectiveness in a wide range of studies over a decade ago. It was precisely that information that prompted infectious disease experts to attempt its use during this outbreak (SARS is a Corona virus after all.) A number of studies from all over the world then and now demonstrate an obvious and effective treatment that is also cheap, well documented in side effects (from use in other conditions) and easy to manufacture and distribute. Trump, a man who sleeps about 4 hours a day and works nearly the other 20 has likely talked to more and better trained experts than the hack author of this utterly deceptive propaganda piece (remember propaganda always clothes an AGENDA) in the last few weeks concerning the current Corona virus than this hack could even have access to. And what did he say? Something to the effect of "we don't have years to wait for a pack of over rated academics to award themsevles tens of millions in grant money to study a treatment to their satisfaction. Does any one else have a better idea? Didn't think so... let's try this. " Omg! Trump said what!? Quickly now let the pearl clutching on mainstream news commence (underwritten massively by the death merchants of our friends in big Pharma, funny no one knows their names.) Really now... as people lay dying on ventalators you're running around with your hair on fire screetching about "Presidential misinformation" becuase he suggested a well known and studied drug likely brought to his attention by some of the best trained minds in the business?

    I doubt you're in-fact that stupud; thus I suspect mal-intent, which under the circumstances is an all time low, even for you.

    1. Thanks this is important information.

      Here is a natural, harmless, FDA approved for food sanitation, substance that appears to me to have a similar mechanism of action.


  3. "I'm not a doctor, but I got common sense" … Trump

    1. Common sense is not allowed in the USSA.

  4. Dr Zelenko treated 700 patients with the following regime.

    hydroxychloroquine 200 mg twice a day for 5 days
    azithromycin 500 mg once a day for 5 days
    zinc sulfate 220 mg once a day for 5 days
    Then Governor Cuomo shut down Dr Zelenko's practice.The governor did not want anyone but doctors in hospitals who participated in his drug trial to prescribe it so people got sicker every day and flooded into hospitals. This allowed the governor to grandstand and rant about poor healthcare. This meant that half of all covid-19 deaths in America were in New York and New Jersey. Why is Zinc Sulfate so important? Because it is the zinc inside the cell that stops the virus from reproducing itself. All
    hydroxychloroquine does is to transport the zinc across the lipid barrier of the cell so the zinc can get inside the cell and cure you. That French doctor and Dr Oz following him left out the zinc. Not Good. Dr Z's patients had such a low viral load that they could not transmit the disease.

    1. All the while an unelected technocrat famous for spying on his customers and forwarding the info the federal government known as Bill Gates (a man with no training or experience in any form of healthcare) is cruising the news talk circut telling everyone the only hope is total electronic monitoring of EVERYONE along with forced vaccination and constant "testing" of EVERYONE. And of course we'd all have to be microchiped like cattle facilitate all of these wonderfuly scientific ideas. No mention is made of the fact that a vaccine for a rapidly mutating RNA virus is a freaking unicorn that would take years to develop if even possible. It would ruin all the sciencey talk to mention such inconvenient details. You're not one of those science denying heretics in a MAGA hat are you? Wonder how your next Bill Gates provided COVID test will turn out if word gets around you don't trust all the sciencey talk.

  5. "The gold standard for a clinical trial is a double-blinded, randomized controlled trial"

    You know or should know a Big Pharma type test will take MONTHS and thousands could die. This drug has been used by MANY physicians as a perfectly legal "off label" FDA Approved drug to TREAT COVID-19 patients; most have had excellent results, with a typical result being their patient was out of ICU in ONE or TWO days.

    Your knowledge of clinical medicine is not up to high school standards.

  6. Years ago a cure for several diseases was developed by Fauci (look it up) and double-blind clinical trials have never been performed even to this day. It is correctly said that aspirin has never received a double-blind clinical trial. This is scienticism at its worst. Hydrozy plus zinc works. It is working all over the world. Articles like this are ignorant fear mongering.

  7. So why did the CDC gave approval if it doesnt work?
