Remdesivir keeps cropping up in the research into the authors of Proximal Origin (especially Scripps) as well as WIV (who have applied to patent it for use in China). Nothing necessarily suss about that but it's worth bearing in mind that Covid-19 will make some people in the drug business supremely wealthy. If you can get your drug up as a possible cure then you've instantly hit the jackpot, regardless of whether your drug actually works in the long run.
In some ways Remdesivir is the gift that keeps on giving. According to wiki:
"Remdesivir was originally developed to treat hepatitis C and was then tested against Ebola virus disease and Marburg virus disease, but was ineffective for all of these viral infections."
On each occasion it would have received funding at the very least.
Now it's being taken for a spin around the block once more with Covid-19, involving massive world-wide sales.
