@Rube,
@Marlene One word: money.
@attheedgeofscience explained many pages ago that companies like Autifony are not big pharmaceuticals, they are small firms with a few staff members and just enough funding from big pharma to carry out their work. If they get a hit drug, sure, they're hugely profitable, but right now all they have is smart doctors and an animal-tested theory.
You notice that all the emails we've had answered were from two of the top people in the company, the CEO and CMO? They don't employ enough people to have underlings field questions.
If and when they have a good UK trial, we'll get our US trial. Just hope I'm old enough to participate!
