I think we will start off with a phase2 and when early results come in, we can jump to EUA.
I wonder how long does it take for B to do it's job? How many days before they see results (i.e. viral load does 50%, patients are removed from ventilators, they get to go home, etc.).
Let's assume 5 days. I would venture to guess we would see EUA within 30 days of the start of phase2.
Once trial starts is when we will our share price no longer bound to gravity ($1B MC) and upon EUA ($3-5B MC) and then possible buyout after 1st of year.
