RE:Unofficial Trials
No. Doing so comes across as very ethically dodgy. If you do a trial in many locations, that happen to include a third world country then that would be ok. Doing it by itself in some place would make the company look like they went somewhere where they could bribe researchers, regulators and all the data would be suspect. Plus doing it that way would make the company look sleazy.
I know it would be great to fly some rutherrin down and utilize a simple xray maching to cure some cancer but too many reasons not to do it.
