French pharmaceutical giant Sanofi said Friday it would offer 100 million doses of hydroxychloroquine, a treatment for rheumatoid arthritis and lupus, to governments worldwide if studies show it can safely to be used to treat COVID-19 patients.
Both hydroxychloroquine, which Sanofi sells under the brand name Plaquenil, and the related compound chloroquine,
an anti-malarial drug, are being studied worldwide as potential weapons in the coronavirus fight.
But proposals to put them to use immediately for more patients have proven highly controversial, with many experts warning there is not yet enough evidence of their safety or effectiveness against COVID-19.
A French doctor in particular, Didier Raoult, has raised hopes by treating patients with a combination of hydroxychloroquine (HQC) and the antibiotic azithromycin, an initiative that many health officials refuse to endorse in the absence of more rigorous studies.
On Thursday, French President Emmanuel Macron met Raoult and his team in Marseille to discuss their latest findings, though the president did not comment publicly on the meeting afterward.
Sanofi acknowledged that "interpretations of the available preliminary data on hydroxychloroquine in the management of COVID-19 differ widely.
