Has FAH approach solved any other real world problems? Has its findings accelerated understanding of any particular disease or helped significantly in developing a cure?
Do keep in mind that 1. very few drug candidates make it through drug trials (iirc it's something around 1 in 1000), and 2. these trials takes 10+ years, and FAH has been around for only 19 years. It's very likely that a bunch of its results are in trial right now, and we'd only hear about it 10-20 years in the future
