If I said that I do not like surprises, or if it's not possible, I would be a liar.
That being said, my previous point stands: If they did, don't you think NWBO would WANT to inform us of an FDA submission?
The following is an excerpt from the attachment you provided:
NWBO has made it known in the past that they would let us know when they submit to the MHRA, and they did. I do not expect any different when they eventually file for the FDA.
I like surprise, but NWBO never gave us any surprise during past 5-8 years. So I believe there is no surprise at all. We just need to wait for MHRA approval at this moment, then wait for next step from the company.
