Is the human lung tissue testing like the CV19 petri dish testing where they have some tissue having CV or some other problem and they are looking to see if upon entry into the petri dish Brilacidin can stop the condition?

Is there more to it than that?
Is info within 2 weeks of testing to be expected or far too short a time to acquire needed info?

I looked up on google and couldn't find answers to above.

Any info would be appreciated.

I thought it was already established that B worked on SARS and MERS and I wonder how they could have established that without knowing that it would not hurt the human lung tissue. I hope that is why so many feel this test should be a slam dunk success for B.
