I lean towards yea simply because I believe this could be structured in a way that could still meet FDA standards. I would hate for this to open up doors to practitioners of pseudoscience convincing families that they can save the lives of their loved ones. However, if someone who is terminally ill has the option to do an experimental treatment where the data could be used as a part of a larger trial, then I'm okay with that. There would still need to be limits and regulations, these people shouldn't be put in a position of simply being experimented on or put in more pain. Of course it should always come down to their consent, and they should be able to back out or change their minds. Knowing you will die and making a choice to do an experimental treatment where it is likely that the best that will come of your participation is that someone else way down the line will survive is an incredibly generous and selfless choice to make. If there are people who are willing to make this choice, I believe we should let them. Our job is to create legation that protects them in making a choice like that.
