New data on Gilead’s remdesivir, released by accident, show no benefit

The antiviral medicine remdesivir from Gilead Sciences failed to speed the improvement of patients with Covid-19 or prevent them from dying, according to results from a long-awaited clinical trial conducted in China. Gilead, however, said the data suggest a “potential benefit.”

A summary of the study results was inadvertently posted to the website of the World Health Organization and seen by STAT on Thursday, but then removed.

“A draft document was provided by the authors to WHO and inadvertently posted on the website and taken down as soon as the mistake was noticed. The manuscript is undergoing peer review and we are waiting for a final version before WHO comments,” said WHO spokesperson Tarik Jasarevic.

Gilead spokesperson Amy Flood said the company believes “the post included inappropriate characterization of the study.” Because the study was stopped early because it had too few patients, she said, it cannot “enable statistically meaningful conclusions.” However, she said, “trends in the data suggest a potential benefit for remdesivir, particularly among patients treated early in disease.”

The data (for details, see screenshot below) will be closely scrutinized but are also likely imperfect. The study was terminated prematurely, which could have affected the results. The context that would be provided by a full manuscript is missing, and the data have not been reviewed as normally occurs before publication.
