No effect when given in late stage severe cases. Unsure effect when given earlier in disease progression but a reduction in “days to improve” in the early administration cohort merits additional research. This happens a lot with covid drug research. Many times treatments given too late have no effect on improving outcomes. That is, if you give it too late, it cannot save you. However, there does appear to be some drugs that improve outcomes when given early in disease progression. Think of it like tamiflu. If you take it 2-3 days post onset, it works. If you take it past that timeframe, it does not work.
