Hydroxychloroquine is looking a big swing and a miss.
"We found no evidence that use of hydroxychloroquine, either with or without azithromycin, reduced the risk of mechanical ventilation in patients hospitalized with COVID-19," the researchers wrote. "An association of increased overall mortality was identified in patients treated with hydroxychloroquine alone. These findings highlight the importance of awaiting the results of ongoing prospective, randomized, controlled studies before widespread adoption of these drugs."
A Brazilian study published on MedRxiv, a pre-print server for studies awaiting peer review, was also halted earlier this month after 11 of 81 coronavirus patients receiving high doses of hydroxychloroquine died.
Trump has suddenly gone quiet on the drug after repeatedly promoting it at his coronavirus news briefings. The president touted a small French study hyped by Fox News, claiming it had a 100% success rate using the drug in combination with azithromycin to treat the coronavirus. But the study's publisher has since said the research did not meet its standards, and The Guardian reported that researchers excluded several patients who died or were taken to the intensive care unit from the results.
The Centers for Disease Control and Prevention also quietly deleted "unusual" guidance for doctors about using the drug. The CDC now warns that "there are no drugs or other therapeutics approved by the U.S. Food and Drug Administration to prevent or treat COVID-19."
