Do such people partake in dangerous medical trials today? I couldn’t find anything about it from some quick googling but if such practices don’t already exist, I doubt we would be able to start them for what would be, in most cases, an intervention not designed to cure a disease or treat a disability.
What do you mean by challenge trials in this context?
In the vaccine context, a challenge trial is a trial where you expose people who get the vaccine to the virus.
That makes little sense in the context of intelligence improvement.
E.g. pay people who are planning on Euthanasia to undergo the treatment, and if it fails then handle the euthanasia.

I’m not sure why you would call that a challenge trial.
I would also be surprised if that’s something you can effectively do.
