Right-to-try is a niche law championed by the Goldwater Institute, a libertarian think tank. Contrary to what Goldwater suggests, right-to-try only covers a small number of niche therapies, namely: last-line personalised medicines (based on analysis of an individual's genetics) for terminally ill patients.

It doesn't have much bearing on medicine though, because the overwhelming majority of such drugs already fall under FDA's compassionate use regulations, and patients access these drug under those existing guidelines.

There have been a few niche cases where right-to-try allowed someone to buy an experimental drug that they would not have otherwise been allowed to buy under compassionate use guidelines. But I want to emphasize that the numbers are tiny.

Like anything in politics, most of the Goldwater Institute's arguments for right-to-try are pure propaganda, although I do think there is an interesting philosophical debate to be had on right-to-try. Nonetheless, the reality is this law has no virtually effect on the landscape of medical science.
