I understand where you're coming from, but as the parent of someone in the field of pharmaceutical research they have a different view.
First, human beings aren't Guinea pigs. Yes, the FDA is slow - for damn good reasons. We didn't use to do things this way and then we changed it to fix problems. There are reasons things are the way they are and it's very well-understood in the medical field. Medicine is not a move fast and cause pain and suffering kind of field or move fast and kill people kind of field. They're very conservative.
Two, since human beings aren't Guinea pigs when we do do experiments on them with drugs that have been through a very thorough and extensive pipeline already, they're looking for very specific things. This tends to make a very small population of patients eligible for a trial.
Three, trials are expensive. These aren't drugs that have been scaled-out in production. The costs tend to be exceedingly exorbitant. The medical field is very well aware of the inelastic demand for their services and this opens up new avenues for the unscrupulous to prey on people. Like the used to do in the "good ol' days."
Finally, the fact the treatment you would like to pursue is still "stuck" in clinical trials is indicative they're not convinced of the efficacy of the treatment. I can tell you lots of "promising" treatments never make it out of clinical trials. That's the nature of the beast. Most ideas are dead-ends.
My advice? Don't chase unicorns. Sadly, I've watched too many people in my family die while chasing unicorns and getting obsessed with treatments that are in trial. There are always treatments in trial. Live your life and enjoy what time you have to the fullest.
