Hey, Rockleo,
1) my recollection is that a sneak peek at 50 people was built into the approved study design and does not have to be requested.
2) I don't think the front line doctors have the info to say who is getting placebo. They may ethically want to throw additional treatments at waning patients, but I don't think they have the perspective to say "damn, he needs leronlimab."
I really doubt they would (or could) break the protocol that way. And that's one reason it's hard to get people into a clinical trial. It's a cost of advancing science.
