Gilead is also trying the same with remdesivir. https://www.scmp.com/tech/science-research/article/3048579/c...

Sample size of 1, but in both cases, the patient appears to have gone from very sick to normal vitals in 48 hrs.

The really nice thing about lopinavir/ritonavir if it works will be... we've already got a lot of it.

Edit: Both cases being the separate administrations of remdesivir & lopinavir/ritonavir.
