3 Questions on NDA's: If we conservatively assume Cytodyn entered into one or more NDA's on 1 Feb 2022, when would we expect to hear something, assuming an agreement was reached?

Do companies usually wait until the expiration of the NDA blackout period before they announce the agreement?

Finally what is the "usual" length of an NDA; 60-90 days?

Just trying to set an expectation on when we might hear something.

Thanks!
