Nah... I see how that might seem logical, but here are a couple things that need to be taken into account...
First, if you recall, the way that drug works is completely different than RLF100... RLF100 hits the lungs directly and protects the ACE2 cells and knocks out all the deadly side effects. Their drug does not... which is why it isn't very effective.
The other thing to consider is that we need a MUCH lower number of cases, because our P-Value is exceptional, due to the superior efficacy... so statistically, we don't need nearly as many cases to get a very strong P-Value.
