There are "right to try" laws both Federally and in 40+ states. It's unfortunate the author doesn't address those, I'm curious how they interact with his case.
"I do not live in a state with a Right to Try law. Can I still use Right to Try?
"Yes. S.204 makes Right to Try the law of the land. So long as a patient and treatment meet the qualifications of the federal law, Right to Try applies, regardless of whether the patient’s state adopted Right to Try."
