That’s really interesting. How early or late in the development process do they kill off drugs? Or does it just depend

Can be anytime really and there’s lots of “go/no-go” checks along the way but the vast majority get killed off before human clinical trials. That is one of the largest costs for drug R&D

Yeah, I remember seeing stat a few years back that for every drug that makes it to market, close to 19 are cancelled before that point. Partially why completed drugs are priced so high before the patent runs out
