I am a smart person, and I am not remotely qualified to make decisions about the risks associated with an untested drug. I’d like to know when I get a prescription that someone else went through the process of being a willing volunteer in a clinical trial.
Frankly, I think most doctors aren't qualified to make such a decision by virtue of lacking PhDs: their expertise is in clinical care, not in evaluating research.
Sure, but the doctor doesn't have to do much research in this case. This is front-page news in the NY Times. And about "every single medication": this is the only approved medication to delay clinical decline due to Alzheimer's. And there are only a few medications to treat symptoms.
I know this isn't a perfect world, but it doesn't seem to be asking a lot for a doctor to know this. (Especially for a drug that currently costs $56K/year and presumably will cost more next year.)
