The trials being put on hold by the World Health Organization are investigating its use as a treatment for patients who are hospitalized with COVID-19, not as a drug to prevent the disease.
However Dr Tedros confirmed that the three other arms of the trial will be continuing, including treatment with remdesivir, lopinavir/ritonavir, and lopinavir/ritonavir with interferon beta-1a.
Tedros said the executive group behind WHO's global "Solidarity" trial met on Saturday and chose to conduct a comprehensive review of all available data on hydroxychloroquine and that its use in the trial would be suspended for now.
The report in the journal Lancet is not a rigorous test of hydroxychloroquine or chloroquine, but it is by far the largest look at their use in real world settings, spanning 671 hospitals on six continents.
He then repeated the claims on Twitter. Only the hydroxychloroquine part of the trial is being put on hold. The FDA has moved mountains - Thank You!
The drugs have now been shown to be tied to a greater risk of death and heart rhythm problems in the study of almost 100,000 patients around the world.
Early study of Covid-19 vaccine developed in China sees mixed results
Two weeks after vaccination, participants in all three groups showed some level of an immune response to the virus. We said earlier in the year that there was an 80% chance of developing an effective vaccine by September.
Officials say they found out the researchers excluded data on patients who didn't respond well to the treatment and that they did not clarify what they meant when they said patients were 'virologically cured'. However, weeks later, the International Society of Antimicrobial Chemotherapy (ISAC) addressed in a statement a few concerns in the research.
Last week, Trump said he'd been taking the malaria drug for a week-and-a-half to stave off the virus. "Finished, just finished", he said in an interview that aired on Sinclair Broadcasting on Sunday. To the best of my knowledge, here I am'. Nevertheless, it has been actively promoted by Trump, who even took a two-week hydroxychloroquine course as a safety measure towards the coronavirus.
'I believe in it enough that I took a program because I had two people in the White House that tested positive, ' he said.
"A lot of good things have come out".
In fact, patients had a higher risk of death and heart rhythm problems than patients who were not given the medicines.
Hydroxychloroquine, which Trump has repeatedly touted as a potential game changer in fighting the coronavirus, is an anti-malarial drug that's also used by doctors to treat rheumatoid arthritis and lupus.
